An auto loan calculator estimates your monthly car payment and the total cost of financing a vehicle. The calculator above gives you both numbers in seconds. Just enter the vehicle price, down payment, interest rate (APR), and loan term. For example, financing a $35,000 car with $5,000 down at 7.5% APR over 60 months results in a monthly payment of $601.14.

This mortgage calculator estimates your monthly principal and interest (P&I) payment and shows the full amortization schedule for your home loan. Enter your home price, down payment, interest rate, and term in the calculator above to see your number instantly. You can also include property taxes and homeowners insurance to see your full monthly payment, known as PITI (principal, interest, taxes, and insurance), the number that actually hits your bank account.

A retirement calculator is a free planning tool that estimates how much money you'll have saved by your target retirement age and how long those savings will last once you begin making withdrawals. Enter your age, current savings, monthly contribution, and expected return in the calculator above to see your projected balance. It also shows your balance in today's dollars, so inflation doesn't fool you. For example, a 35-year-old saving $500 a month could have about $1,097,072 by age 67.

This investment calculator shows how your money could grow over time based on your starting balance, regular contributions, and chosen annual return. Enter your numbers above to see your estimated future balance. For example, if you start with $10,000 and contribute $500 a month at a 7% annual return, your balance grows to about $300,851 over 20 years. You put in $130,000, and compounding adds $170,851 in growth.

This portfolio calculator estimates your investment mix's expected return, risk, and long-term growth based on how your money is divided among stocks, bonds, real estate, and cash. Enter your holdings above to see your projected return, volatility, and Sharpe ratio in seconds. The figures are based on long-run historical averages used as model assumptions, so treat them as estimates, not guarantees. Use the calculator to see how changes to your asset mix affect the balance between risk and reward. It models only an unleveraged mix. If you're borrowing against the account itself, see our guide to portfolio margin and leverage to understand how that risk works instead.

The rental property calculator above helps you determine whether a single-family rental is a smart investment. Enter the purchase price, rent, loan terms, and expenses, and you'll see the cash flow, cap rate, cash-on-cash return, and long-term ROI in seconds. It's designed for first-time buyers and seasoned landlords alike. The detailed guides below explain each metric so you can read your results with confidence.

Use this free net worth calculator to add up your assets, subtract your debts, and see how you compare with Federal Reserve benchmarks. In the calculator above, enter your cash, investments, retirement accounts, home equity, and vehicles, then add your mortgages, loans, and credit card balances. In seconds, you will see your total net worth, your liquid net worth, and your debt-to-asset ratio.

A budget calculator gives every dollar a plan by dividing your take-home pay among needs, wants, and savings. The calculator above uses the popular 50/30/20 rule: 50% of income goes to needs, 30% to wants, and 20% to savings and debt payoff. It also includes a zero-based mode for budgeting every dollar to zero. Enter your monthly income and spending to see your targets, where you're over, and how much you have left to assign. For example, if you take home $5,000 a month after tax, the 50/30/20 rule allocates $2,500 to needs, $1,500 to wants, and $1,000 to savings.

A tax resolution calculator matches your IRS debt with the specific relief program most likely to work: Offer in Compromise, installment agreement, Currently Not Collectible, penalty abatement, or Innocent Spouse Relief. The calculator above does this in seconds. Just enter how much you owe, your monthly income, your allowable living expenses, your net asset equity, and whether the debt is joint. For example, if someone owes $42,000, has $700 a month in disposable income, and has $8,000 in equity, their IRS Reasonable Collection Potential is $16,400, the floor for a viable Offer in Compromise.

An estate planning calculator uses your family and asset situation to identify the specific documents you need, from a simple will to a full estate plan with irrevocable trusts. The calculator above gives you a recommendation in seconds based on six inputs: state, net worth, marital status, kids, cross-state property, and any special-needs dependents. For a married couple with kids and $850,000 in net worth living in California, it recommends a will with guardianship nomination, durable powers of attorney, and healthcare directives. The attorney cost is $750 to $2,500, compared with $199 to $299 through online services like Trust & Will or LegalZoom. For the full document checklist, help with the DIY-vs-attorney decision, and the right order to tackle everything, see our first-time estate planning guide.

A probate calculator estimates how much it will cost (and how long it will take) to probate an estate in your state. That includes attorney fees (statutory in 9 states and reasonable-fee in ~41), executor commission, court filing fees, and any ancillary probate required for out-of-state real property. Where an actual state fee schedule exists, the calculator above applies it. California follows Cal. Prob. Code §10810, with 4%/3%/2%/1%/0.5% tiers. Florida follows Fla. Stat. §733.6171, with a $1,500 base plus tiered percentages. Another 7 states have their own statutes. For a moderate California estate valued at $750,000, the total probate cost runs about $36,000 to $42,000 over 15 to 30 months. By comparison, a revocable living trust that would have avoided probate entirely costs $2,025 to $6,750.

An elder care planning calculator uses your age, assets, income, and long-term care outlook to identify the specific planning steps that can protect assets from the median nursing home cost of $115,000 per year while preserving Medicaid eligibility. The calculator above uses the 2026 federal figures: a Community Spouse Resource Allowance of $32,532-$162,660, an MMMNA minimum of $2,644, an institutional income cap of $2,982/month, and the 60-month lookback under 42 U.S.C. §1396p(c). For a married couple, both age 62, with $550,000 in countable assets and possible LTC needs within 5 years, the recommendation is to fund a Medicaid Asset Protection Trust now, attorney-drafted for $3,000-$6,000. Every month of delay compresses the lookback window and shifts assets from protected to countable.

A Trump Account calculator shows how the new $1,000 federal seed, along with the contributions you make each year, could grow by the time your child turns 18. Enter your child's age, the seed amount, and the annual contributions from your family and any employer in the calculator above to see the projected value. For example, a newborn's $1,000 seed, plus $200 a month at a 7% annual return, grows to about $89,657 by age 18: $44,200 put in and $45,457 in tax-deferred growth.

A 529 savings calculator shows how much your college fund could grow by the time your child turns 18 and whether it will cover the cost of college. In the calculator above, enter your child's age, current balance, monthly contribution, and expected return. For example, starting with $0 and saving $300 a month at a 6% return grows to about $116,206 over 18 years, $64,800 in contributions and $51,406 in tax-free growth. Add a college-cost target, and the tool will also show your projected coverage and the monthly amount needed to fully fund it.

A Coast FIRE calculator shows whether your current retirement savings will grow into a full retirement nest egg by your target retirement age without any additional contributions. Enter your age, current savings, expected return, and desired retirement spending in the calculator above. For example, a 35-year-old with $150,000 saved who plans to retire at 65, expects a 7% return, and wants to spend $60,000 a year needs $197,051 invested today to coast. That saver is not quite there yet and needs to keep contributing.

A business loan payoff calculator shows how much sooner you can pay off a standard term loan (such as an SBA 7(a) or bank loan) by putting extra money toward your monthly payment. Enter your remaining balance, rate, remaining term, and any extra amount in the calculator above. For example, if you have a $100,000 balance at 9.5% APR with 60 months left, paying an extra $300 each month pays off the loan 9 months sooner and saves $4,187 in interest.

A personal loan calculator estimates your monthly payment on an unsecured personal loan. When used correctly, it also shows the loan's true cost after fees. Enter your loan amount, interest rate, and term in the calculator above to see your payment instantly. For example, a $15,000 loan at 12.5% APR over 48 months costs $398.70 per month. But if the lender charges a 3% origination fee, you receive only $14,550 up front, pushing your real effective APR above the stated 12.5% rate.

An interest per day calculator shows how much interest a balance earns (or how much a loan costs) in a single day. Enter a balance and its annual rate above to instantly see the daily, weekly, and monthly dollar amounts. For example, $10,000 at a 4.5% annual rate earns about $1.23 a day, $8.63 a week, and $36.99 over a 30-day month. Most day-rate tools stop there. This one also shows the effective annual yield (APY) when that daily rate compounds daily, the number that actually appears in your account balance a year later.

A taxable vs. tax-deferred calculator compares how much your money could grow in a regular brokerage account and a tax-deferred account, such as a traditional 401(k) or IRA, using the same starting balance, contributions, and return. Enter your numbers above to see the final balances side by side. For example, if you start with $10,000 and add $6,000 a year for 25 years at a 7% return, taxed at 24%, the tax-deferred account ends up meaningfully larger than the taxable one, even though it owes a bigger one-time tax bill at the end.

A credit card payoff calculator shows how long it will take to clear a balance and how much interest you'll pay, based on your APR and monthly payment. Enter your balance and APR in the calculator above, along with either a monthly payment or a target payoff date. For example, a $6,000 balance at 24% APR, paid at $250 a month, is paid off in 34 months and costs $2,255.61 in interest. The calculator also automatically shows the minimum-payment-only path. With the same balance and rate, making minimum payments alone takes 252 months (about 21 years) and costs $10,886.92 in interest. That's over $8,600 more than the $250-a-month plan for the same starting balance.

This IUL calculator projects an indexed universal life (IUL) policy year by year, showing what the cap and the cost of insurance actually take out of it. Every guide we write here starts with the math. For an indexed universal life policy, that math turns on charges the sales illustration tends to leave in the footnotes, the same charges that fund the commission an agent earns for selling the policy in the first place. Enter your premium, death benefit, and the cap and participation rate you were quoted. The calculator's year-by-year projection table shows the cash value, surrender value, and death benefit through the age you choose. Alongside it, the calculator puts the same premium into a 401(k) or a taxable brokerage account, letting you see both paths at once. The calculator is free to use, with no signup and no Excel file to download. As you change the premium, cap, participation rate, or cost-of-insurance inputs, the table updates using the numbers you enter rather than one carrier's hard-coded rates. Using the numbers loaded above, a 40-year-old who pays $12,000 a year for 20 years into a $500,000 policy reaches a surrender value of $583,785 at age 70. With no cap, the same policy would have reached $1,277,172. The cap cost $693,386, while the cost of insurance took another $49,109.

This MCA calculator shows the true cost of a merchant cash advance in seconds. Enter your advance amount, factor rate, and estimated term, and the tool will calculate your total payback, cost of capital, and true effective APR. Here's the default example: A $50,000 advance with a 1.30 factor rate and an estimated 12-month term results in a total payback of $65,000. That includes $15,000 in cost of capital. With daily payments of $257.94 (about $5,416.67 per month across 252 payments) the effective APR is 54.81%.

This invoice factoring calculator shows exactly how much cash you'll get now, and what the factoring deal really costs. Enter the invoice amount, advance rate, factoring fee, and how quickly your customer pays. The calculator then gives you your upfront cash, the reserve held back, total fees, and true annual cost. For example, with a $100,000 invoice, an 85% advance rate, and a 1.5% fee per 30 days, you receive $85,000 in cash now and hold a $15,000 reserve. If your customer pays in 45 days, the total factoring fee is $3,000, your $12,000 rebate is released, and your net proceeds are $97,000, an effective APR of 28.63%.

This business line of credit calculator shows your monthly payment and the true cost of the money you draw. Just enter your draw amount, APR, repayment term, and any draw fee. Because a line of credit is revolving, you pay interest only on the amount you actually draw, not your full credit limit. For example, if you draw $50,000 at a 12% APR over 24 months with a 2% draw fee, your monthly payment is $2,353.67. You pay $6,488.17 in interest, plus a $1,000 draw fee. That puts the total cost of the money at $7,488.17, with an effective APR of 14.05% once the fee is counted.

A PTO cash-out calculator converts unused paid time off, vacation, or leave days into a dollar amount. It calculates your daily pay rate, then multiplies that rate by the number of days you choose to sell back. Enter your salary or hourly rate, the number of leave days you have available, and how many you want to cash out. The calculator above will show your gross payout, an estimated net payout based on a simple flat tax-rate estimate, and what those same days would have been worth as paid time off instead. For example, someone earning $72,000 a year on a standard five-day work week has a daily rate of about $276.92. Selling 5 days would produce a gross payout of about $1,384.62, or roughly $1,080 after a 22% tax-rate estimate.

A zakat calculator works out the 2.5% you owe on your zakatable wealth once it clears the nisab threshold, the minimum amount that must be reached before zakat becomes due. In the guides we publish here, every calculator is built around a number you can verify today. This one uses today's gold or silver price to derive the nisab threshold live, rather than hardcoding a dollar figure that can go wrong within days of a price move. Enter your cash, investments, gold, and silver, add any money owed to you, and subtract debts and bills due now. The calculator above then returns your zakatable wealth, your nisab threshold, and the zakat due if you clear it.

A life insurance needs calculator determines the total death benefit required to protect your dependents if your income disappears. The math is straightforward. At ModernWallet, we calculate recommended coverage by adding future income needs to existing debts and subtracting liquid household assets. Consider an illustrative household. Assume you need to replace $70,000 in annual income for 15 years. You also carry $10,000 in personal debt and a $250,000 mortgage balance. You budget $15,000 for final expenses and $60,000 for a child's college fund. These obligations total $335,000 on top of your income replacement. Your income replacement does not require a simple multiplication of $70,000 by 15 years. Invested lump sums earn returns over time. Discounted at a 3% real annual rate, that 15-year income stream equals roughly $835,655 today. Now subtract your existing resources. If you have $50,000 in current coverage and $30,000 in liquid savings, your family holds $80,000 in assets. Combining those figures leaves a recommended policy amount of approximately $1,090,655. This worked scenario reflects our baseline assumptions, but your own coverage target will depend entirely on your specific household balance sheet.

Self-employment tax is 15.3% — 12.4% for Social Security and 2.9% for Medicare — charged on 92.35% of your net business profit, which works out to an effective 14.13% of profit. The calculator above applies the 2026 figures (a $184,500 Social Security wage base and the current federal brackets) and answers the question people actually have: what share of each payment isn't yours to spend. On $60,000 of net profit, a single filer owes $8,477.73 in self-employment tax and about $12,037 in total federal tax — roughly 20.1% of profit, or $3,009 per quarter.

An operating cash flow calculator measures the net cash a business generates from its regular operations over a given period. Net income records revenue and expenses when earned or incurred, but operating cash flow tracks the actual dollars moving into and out of your bank account. For example, a business with $120,000 in net income, $25,000 in depreciation, and $5,000 in amortization has $30,000 in non-cash add-backs. If accounts receivable grew by $15,000, inventory grew by $10,000, and accounts payable grew by $8,000 during the same period, working capital tied up $17,000 in net cash. Adding the $30,000 in non-cash expenses and subtracting the $17,000 working capital change leaves $133,000 in operating cash flow. At ModernWallet, we built this operating cash flow calculator to help operators evaluate real liquidity before taking on debt or signing a bank covenant. Commercial lenders evaluate this metric closely. Accounting profit cannot service monthly loan payments if customers have not paid their invoices. Enter your net income, non-cash charges, and working capital movements above to calculate your cash from operations instantly.

The business standard mileage rate for 2026 is 72.5 cents per mile from January 1 through June 30 and 76 cents per mile from July 1 through December 31 — the IRS raised it mid-year. Any calculator that multiplies your annual miles by a single rate gives the wrong answer, so the tool above takes each half of the year separately. A driver with 5,000 business miles in the first half and 7,000 in the second deducts $8,945, at a blended 74.54 cents per mile. In the 12% bracket that deduction is worth $2,337 — because it cuts self-employment tax as well as income tax.

A cash conversion cycle calculator measures the number of days a business takes to convert inventory investments into cash collections from customers. It tracks your working capital timeline. For example, take a business with $600,000 in annual cost of goods sold and $1,000,000 in annual revenue. It maintains $90,000 in average inventory, $110,000 in average receivables, and $70,000 in average payables over a 365-day year. Its inventory sits for 54.8 days. Customer payments take 40.2 days to arrive. The company takes 42.6 days to pay its own suppliers. This produces a cash conversion cycle of 52.4 days. Every dollar invested in inventory remains tied up for over seven weeks before flowing back into the company. At ModernWallet, we see business owners use this metric to decide how much financing they need to bridge operating gaps. That 52.4-day span is a funding gap. You have paid your vendors, but customer cash has not yet arrived. Without cash reserves, you must finance those 52.4 days of operations. Many owners guess their financing needs and take on excess debt. This cash conversion cycle calculator provides an exact day count based on your financial statements. You can immediately see whether collections, inventory turnover, or vendor terms drain working capital.

A freelance rate has to cover more than a salary does: both halves of Social Security and Medicare, every hour you work but cannot bill, your own unpaid time off, and your overhead. The calculator above works backwards from the take-home pay you want to the hourly rate that produces it, using real 2026 tax figures instead of a rule-of-thumb markup. To take home $70,000 while billing 25 hours a week for 46 weeks with $6,000 of overhead, you need $95,016 of revenue — an hourly rate of $82.62, or $661 a day.

A home equity line of credit (HELOC) calculator shows how much borrowing power your home equity supports and what your monthly payment will be during both the draw and repayment periods. Enter your property value, remaining mortgage balance, the lender's combined loan-to-value (CLTV) limit, your planned draw, and your annual percentage rate (APR) in the tool above. For example, consider a $400,000 home with a $250,000 mortgage balance and a lender combined loan-to-value cap of 85%. The most your equity supports is $90,000. If you draw $50,000 at 8.5% APR with a 10-year draw period and a 20-year repayment period, your combined loan-to-value after the draw is 75%. During the draw period, an interest-only payment is $354.17 a month, totaling $42,500 in interest over 10 years. In the repayment period, the monthly payment increases by $79.74 to $433.91, generating $54,138.79 in interest over 20 years. That brings the total interest across 30 years to $96,638.79.

An S corporation election lets you split business profit into a salary, which pays payroll tax, and a distribution, which does not. The saving is real, but it is smaller than the usual pitch suggests, because two costs come off it: running payroll, and the qualified business income deduction you give up on every dollar moved into salary. On $120,000 of profit with a $60,000 salary, the election avoids $7,775 of payroll tax — but forfeits an $8,242 QBI deduction and costs $1,200 in payroll. The honest net saving is $4,171.

A commercial mortgage calculator shows the monthly payment, the balloon balance due when the term ends, and how property income covers annual debt service. For example, purchase a $1,000,000 property with a 75% loan-to-value (LTV) ratio. The loan amount is $750,000, and the down payment is $250,000. Apply a 7% interest rate (APR) over a 25-year amortization schedule with a 10-year loan term. The monthly principal-and-interest payment is $5,300.84, which equals $63,610.13 in annual debt service. Over the 10-year term, principal paid down equals $160,249.53, while total interest reaches $475,851.75. When the 10-year term ends, the remaining balloon balance owed is $589,750.47. If the property generates $100,000 in net operating income (NOI), the debt service coverage ratio (DSCR) is 1.57x, and the debt yield is 13.3%.

A CD calculator shows the final balance and total interest earned on a certificate of deposit based on your deposit, rate, and term. For example, take a $10,000 deposit at a 4.5% APY for 12 months. That balance reaches $10,450.00 at maturity, producing $450.00 in total interest. At a 22% tax rate, the interest after tax comes to $351.00. That return averages $37.50 in monthly earnings across the full term.

An emergency fund calculator turns your essential monthly bills and the number of months you choose into a savings target. Enter your must-pay expenses across the seven categories, the months you want covered, your current savings, your planned deposit, and an optional savings yield in the calculator above. For example, monthly essential costs of $3,000 covered for 6 months create an emergency fund target of $18,000. If you have $3,000 saved so far, that balance covers 1.0 month of bills. The remaining gap is $15,000 to save. Adding a deposit of $400 a month with no yield reaches that target in 38 months, or 3 years 2 months. If your goal is to finish saving within 12 months with no yield, the required monthly deposit is $1,250.

A debt consolidation calculator shows whether replacing multiple existing balances with one fixed-rate loan lowers your monthly payment and your total interest after fees. For example, take three debts. The first is $8,000 at 24% annual percentage rate (APR), paid at $250 a month. The second is $5,000 at 19% APR, paid at $150 a month. The third is $3,000 at 29% APR, paid at $100 a month. Together, those balances total $16,000 and require $500 a month in payments. Keeping those debts as they are takes 55 months to clear the last balance and costs $9,469.39 in interest. Now take a 48-month consolidation loan at 12% APR with a 3% origination fee. It produces a $434.37 monthly payment. That payment is $65.63 less each month, and consolidating costs $4,619.50 less overall once the fee is counted.

An inflation calculator shows what an amount of money will cost or buy in the future at an average annual inflation rate you choose. Enter an amount in today's dollars, a number of years, and an inflation rate in the calculator above. You can also add an optional annual return if the money is invested. The tool has no historical price data built in. For measured price changes, use the Consumer Price Index (CPI) data from the Bureau of Labor Statistics (BLS). For example, enter $10,000, a 3% inflation rate, and 10 years. The same purchases then cost $13,439. Held unchanged, the $10,000 buys only what $7,441 buys today. That is a 25.6% loss of buying power. Kept as cash, the money has a real return of -2.91% a year. Add a 5% annual return and the real return after inflation becomes 1.94% a year. The balance grows to $16,289, which is worth $12,121 in today's dollars.

An expense ratio calculator shows how much a fund's annual fee costs over time by comparing the ending balances of two funds that differ only in their expense ratio. Enter your starting balance, monthly contribution, years invested, an assumed return before fund costs, and the expense ratio of Fund A and Fund B in the calculator above. It returns each fund's ending balance, the dollar gap between them, the growth each ratio takes compared with a no-fee benchmark, and the total you put in. For example, start with $10,000, add $500 a month, and invest for 30 years. Assume a 7% return before fund costs, then give Fund A a 0.05% expense ratio and Fund B a 1% ratio. Fund A ends at $654,429 and Fund B ends at $544,691, a gap of $109,738 from the same deposits.

A Social Security break even calculator finds your break-even age, which is the age past which claiming later instead of earlier has paid you more in total. For anyone born in 1960 or later, full retirement age is 67. Waiting from 62 to full retirement age breaks even at age 78 and 8 months. Waiting from full retirement age to 70 breaks even at age 82 and 6 months. Enter your own benefit, birth year and two claiming ages in the calculator above to find your break-even age. For example, take a $2,000 monthly benefit at full retirement age for someone born in 1962. Claiming at 62 pays $1,400 a month, and claiming at 67 pays $2,000. Claiming at 70 pays $2,480 a month. By age 80, the claim at 62 has paid $302,400 in total. The claim at 67 has paid $312,000 by then. By age 85, those totals reach $386,400 and $432,000.

A mileage reimbursement calculator works out what you're owed by multiplying business miles by a rate per mile. Unless your employer sets its own rate, use the Internal Revenue Service (IRS) business rate: 72.5 cents a mile for January through June 2026, and 76 cents a mile from July 1. Enter your miles for each half of the year in the calculator above, plus your employer's rate if it has one. Under an accountable plan, a reimbursement at or below the IRS rate is not taxable wages. For example, say you drive 1,200 business miles from January to June and 1,000 miles from July to December. At the IRS rates, the first half pays $870 and the second half pays $760. That's a total reimbursement of $1,630, a blended rate of about 74.09 cents a mile. If your employer pays 80 cents a mile instead, you get $1,760. The $130 above the IRS-rate amount counts as taxable wages. At 60 cents a mile, you get $1,320, which is $310 less than the IRS-rate amount.

A portfolio rebalancing calculator shows how much to buy or sell in each holding: multiply the holding's target percentage by the portfolio total, then subtract what the holding is worth now. A positive result is the dollar amount to buy, and a negative result is the amount to sell. Enter the current value and target percentage for Stocks, Bonds, Real estate / other, and Cash in the calculator above, plus any new money you plan to invest. For example, take a portfolio with $70,000 in Stocks, $25,000 in Bonds and $5,000 in Cash. That is a total of $100,000, and the current split is 70% / 25% / 5%. Say the target is 60% Stocks, 35% Bonds and 5% Cash. The calculator says to sell $10,000 of Stocks and buy $10,000 of Bonds, while Cash needs no trade. If you would rather not sell, check the new-money-only box: adding $30,000 lands the portfolio exactly on target without a single sale.

A hurricane deductible calculator turns a Florida hurricane deductible into dollars by multiplying the deductible percentage by the dwelling coverage limit. Enter the dwelling limit, the deductible option, and the amount of covered hurricane damage in the calculator above, plus any part of the deductible an earlier hurricane already used this year and your policy's all-other-perils deductible (it starts at $1,000, the figure in the Florida CFO example). It returns the deductible, what you pay, what the insurer pays, and the balance left for any later hurricane this calendar year. For example, take a $300,000 dwelling limit. A 2% hurricane deductible on that limit comes to $6,000. At 5% the same limit carries a $15,000 deductible, and the 10% option raises it to $30,000. Say a hurricane causes $40,000 of covered damage and the policy carries the 5% option. You pay the $15,000 deductible and the insurer pays the remaining $25,000. Under the 10% option, $9,000 of damage falls short of the $30,000 deductible, so you pay all of it and the insurer pays nothing.

An annuity calculator finds one of three numbers: what a lump sum pays out each period, what level deposits grow to, or what a stream of payments is worth as one sum today. Pick the question in the calculator above, then enter the amount, the interest rate, the term in years, and how often payments happen. You also choose whether each payment falls at the end of the period or at the start. For example, take a $100,000 lump sum paid out over 20 years at 5% a year, with a payment at the end of each month. The calculator returns $659.96 a month across 240 payments. Those payments total $158,389.38, and $58,389.38 of that is interest. Shorten the term to 10 years and the payment rises to $1,060.66 a month. The 5% rate is a placeholder, so replace it with the rate you want to test.

A credit card interest calculator finds one billing cycle's interest by dividing your annual percentage rate (APR) by the days in the year, then multiplying that daily rate by your average daily balance and by the number of days in the cycle. Enter your starting balance, APR, cycle length and 365- or 360-day basis in the calculator above. You can also add a payment made during the cycle and the day it posts. The calculator then shows the daily periodic rate, the average daily balance, the yearly cost if the balance stays flat, and the effective annual rate with daily compounding. For example, take a $5,000 balance at 24% APR with no payment during the cycle. The cycle runs 30 days, and the daily rate uses a 365-day year. That gives a daily rate of 0.0658%, an average daily balance of $5,000, and interest of $98.63 for the cycle. If a $1,000 payment posts on day 11, interest for the same cycle drops to $85.48. That payment saves $13.15 compared with paying nothing during the cycle.

A loan payment calculator works out the monthly payment, total interest and total cost of a fixed-rate installment loan from three inputs: the loan amount, the annual percentage rate (APR) and the term in years. Enter the amount, rate and term from a lender's offer in the calculator above, replacing the placeholder figures it starts with. Add an optional extra monthly payment to see how much sooner the loan ends and how much interest that extra money saves. For example, take a $25,000 loan at 8% APR over 5 years. The payment is $506.91 a month, so you pay $30,414.59 in total, and $5,414.59 of that is interest. Adding $100 a month clears the loan 11 months sooner and cuts total interest by $1,089.30.

The account with the higher annual percentage yield (APY) earns more, as long as the savings rate holds for your term. This HYSA vs CD calculator compares a certificate of deposit (CD) with a high-yield savings account (HYSA) on the same deposit and term, then shows the savings rate that would tie them. The starting APYs are placeholders, so enter your deposit, your term in months and the rates on the CD and savings account you are weighing. Take a $25,000 deposit held for 12 months. The CD pays 4.25% APY and the HYSA pays 4.00% APY. The CD earns $1,062.50 and the HYSA earns $1,000.00, so the CD comes out $62.50 ahead if both rates hold.

Yes, a child can have both a Trump Account and a 529. The account that should get this year's money depends on whether the money will pay for college. For college, the 529 usually leaves more because qualified education withdrawals are free of federal income tax, while the Trump Account taxes the seed and the growth. If the money is cashed out at 18 for something else, the Trump Account can leave more. Enter your child's age, yearly savings, expected return and tax rate in the Trump Account vs 529 calculator below to see which account leaves more for your family. Take a newborn who gets the $1,000 seed, with $2,400 a year going in at a 7% return. The money pays for college, and the tax rate on the withdrawal is 12%. The 529 reaches $86,144.21 at 18 and owes no tax. The Trump Account reaches $89,656.74, but $5,574.81 of tax leaves $84,081.94. The 529 comes out $2,062.27 ahead.

A recast lowers your monthly payment by spreading a smaller balance over the same months left at the same rate. Enter your current balance, interest rate, months left and lump sum in the mortgage recast calculator below, along with any recast fee your servicer charges. The calculator returns the new payment, the interest saved and the months a fee takes to earn back, and it also shows the same lump sum prepaid without a recast. For example, take a $238,000 balance at 6.875% with 312 months left. The payment is $1,639.33 a month in principal and interest. A $30,000 recast cuts it to $1,432.69, which is $206.64 a month less.

A Social Security cost-of-living adjustment (COLA) calculator finds your 2027 benefit by multiplying your current monthly benefit by 1.036 and rounding down to the dime. If a Medicare Part B premium comes out of your check, subtract it and round the payment down to the whole dollar. The Social Security Administration (SSA) set the 2027 COLA at 3.6%. Enter your benefit in the Social Security COLA calculator below to see your own 2027 amount. For example, take a $2,000 monthly benefit before any Medicare deduction. Multiplied by 1.036, it becomes $2,072.00 in 2027. That is $72.00 more a month and $864.00 more over 12 months. A $1,642 benefit, SSA's estimated average for all disabled workers before the raise, becomes $1,701.10. That is $59.10 more a month. A $2,095 benefit, the estimated average for retired workers, becomes $2,170.40, or $75.40 more each month.

On a $300,000, 30-year loan at 6.5%, biweekly payments end the mortgage about 70 months sooner. Enter your balance, rate, months left and any plan fees in the biweekly mortgage calculator below to see the result for your own loan. It returns the months saved, the interest saved and the half-payment, and it also shows the same 13th payment made with no biweekly plan. Take a $300,000 balance at 6.5% with 360 months left. At ModernWallet, we ran that loan three ways in an internal calculation: monthly, biweekly, and monthly with 1/12 of a payment added. The monthly payment is $1,896.20, and biweekly half-payments of $948.10 save $88,121.78 in interest. Adding $158.02 a month instead saves $87,256.29, which is $865.49 less and needs no plan. You can check every figure by changing the inputs in the calculator.

The Roth finishes ahead when your tax rate in retirement is higher than your rate today, the Traditional finishes ahead when it is lower, and the two finish even when the rates match. Enter your yearly deferral, tax rate today, retirement tax rate, annual return and years until withdrawal in the tool above to see who finishes ahead and by how much. For example, put $10,000 a year into a Traditional 401(k) at a 22% tax rate today, assuming a 7% annual return over 25 years. The equal-take-home Roth deferral is $7,800 a year. After 25 years, the tax-free Roth balance is $526,547, while the Traditional balance before tax reaches $675,060. If your retirement tax rate matches today's rate at 22%, the tax on the Traditional balance is $148,513, leaving $526,547 after tax. Both accounts finish even. If your retirement rate drops to 12%, the Traditional finishes $67,506 ahead; at 32%, the Roth does.

Pay off the mortgage when your expected return is below the break-even return. If your expected return is above it, invest the extra instead. Enter your balance, mortgage rate, months left, extra cash each month, expected annual return and tax rate on gains in the pay off mortgage or invest calculator below. It shows which path ends ahead after tax and by how much, the break-even return, the interest saved by paying off early and how much sooner the loan is gone. Take a $300,000 balance at 6.5% with 360 months left. You have $300 extra a month, expect a 7% return and pay 15% tax on gains. The monthly payment is $1,896.20. In our internal calculation, we followed the same $300 a month both ways, month by month. Paying off early ends $8,188.38 ahead because the 7% return sits below the 7.19% break-even. You can check the result by changing any input.

Florida Amendment 3 property tax savings equal your extra exempt value multiplied by your non-school millage rate. At the 10.5-mill statewide average, savings are about $1,035 in 2027 and about $2,085 in 2028 for homes assessed above $250,000. Lower-valued homes save less because the exemption cannot exceed the assessed value of the property. Take a home with an assessed value of $400,000 taxed at 10.5 mills. The non-school property tax bill today is $3,660.18 under the current $51,411 exemption. In 2027, the bill drops to $2,625.00 for a savings of $1,035.18. In 2028, the bill falls to $1,575.00, saving you $2,085.18 each year.

The government can take up to 15% of your disposable pay per paycheck for a defaulted federal student loan. Disposable pay is what remains after legally required withholdings are subtracted. On $2,000 of disposable pay every two weeks, that is $300 per paycheck. It adds up to about $650 a month and $7,800 a year. Enter your own balance, disposable pay, pay frequency, tax refund and Social Security benefit in the calculator above to replace its starting figures. For example, take a $30,000 defaulted balance with $2,000 of disposable pay every two weeks. Add an expected $3,000 federal tax refund and no Social Security. Wage garnishment takes $7,800 in the first year, and the refund offset takes the full $3,000. That puts first-year exposure at $10,800. Garnishment alone would need about 47 months to clear the balance.

Your tax bracket is the rate on your last dollar of taxable income. The tax bracket calculator above finds your taxable income by subtracting a deduction from your income before deductions. It uses the standard deduction unless you enter your own total. Add your filing status to see your 2026 federal bracket, estimated tax and effective rate, plus the room left before the next bracket starts. For example, take a single filer with $85,000 of income and the $16,100 standard deduction. Taxable income is $68,900, so the top dollars land in the 22% bracket and the tax comes to $9,870. That is an effective rate of 11.6%, with $36,800 of room before the 24% bracket starts.

Divide your monthly debt payments by your gross monthly income, then multiply by 100. The result is your debt-to-income (DTI) ratio, which the Consumer Financial Protection Bureau (CFPB) defines as all your monthly debt payments divided by your gross monthly income. Enter your income and each payment in the debt to income ratio calculator below to see your DTI, your housing-only ratio and your total monthly debt payments. It also shows how much more you could pay each month before reaching the 36%, 45% and 50% limits in the Fannie Mae Selling Guide. For example, take $6,500 of gross monthly income. Housing costs $1,650 and the auto loan costs $450. Student loans add $250 and card minimums add $120, for $2,470 a month. That is a 38.0% DTI, which is $130 over Fannie Mae's 36% limit on a manually underwritten mortgage. You still have $455 of room before the 45% line.

You figure the taxable amount from your provisional income. Provisional income is half your Social Security benefits plus all your other income and any tax-exempt interest. Above $25,000 (single) or $32,000 (married filing jointly), up to 50% of benefits is taxable. Above $34,000 or $44,000, up to 85% is taxable. The Social Security taxable benefits calculator below returns the taxable part, your provisional income, the share of benefits taxed and which tier applies. For example, take a married couple filing jointly with $42,000 of benefits and $30,000 of other income. Their provisional income is $51,000, and $11,950 of their benefits is taxable. That is 28.5% of the benefits.

Charitable donations lower your 2026 taxes only if your itemized deductions exceed the standard deduction, or through the non-itemizer cash allowance. Most households take the standard deduction, which is $16,100 for single filers and $32,200 for married couples filing jointly under IRS 2026 inflation adjustments. Non-itemizers can deduct cash gifts up to $1,000, or $2,000 on a joint return. Itemizers face a floor of 0.5% of adjusted gross income (AGI). The charitable donation tax deduction calculator below compares both routes, shows what your giving adds, and tests two-year bunching. For example, take a married couple filing jointly with $150,000 AGI who give $12,000 in cash and have $20,000 of other itemized deductions. Their deductible giving after the $750 floor is $11,250, bringing their itemized total to $31,250. The standard deduction plus the $2,000 cash allowance gives them $34,200, so the standard route wins. Giving adds $2,000 of deductions, which saves $440 at a 22% marginal tax rate.

You can deduct up to $10,000 of car loan interest each year if your income qualifies. The deduction phases out above $100,000 of modified adjusted gross income (MAGI), or $200,000 for married couples filing jointly. Every $1,000, or part of $1,000, of MAGI above those limits cuts the deduction by $200. The car loan interest deduction calculator below shows your allowed deduction, your phase-out reduction, and your federal tax savings. For example, take a single filer with $95,000 of MAGI who pays $4,200 in interest on an eligible vehicle loan. Because income is under the $100,000 threshold, no phase-out applies. They deduct the full $4,200, which saves about $924 in federal tax at a 22% marginal rate. At $120,001 of MAGI, that same interest yields no deduction.

Buy only if you will stay in the home past the break-even year. That year depends on your mortgage rate, your rent, how fast the home gains value and what your invested cash earns. The defaults are a $400,000 home, $2,200 monthly rent and a 7.32% mortgage rate. With those inputs, the modeled break-even is year 21, and a 5% rate moves it to year 5. The rent vs buy calculator below compares your net worth if you buy with your net worth if you rent and invest the same cash. It also shows the year buying pulls ahead. In our internal modeling, we took a buyer who puts 20% down on the default $400,000 home and pays 3% in closing costs. That is $92,000 of cash on day one and a $320,000 loan. At 7.32% over 30 years, the principal and interest payment is $2,198.18 a month. Adding property tax, insurance and maintenance brings the first-month cost of owning to $3,032. A similar rental costs $2,215 a month with renter's insurance. The renter invests the $92,000 and the $817 monthly difference at a 6% return. Seven years in, buying leaves $169,338 and renting and investing leaves $210,495, so renting leads by $41,156.

Your tax depends on how long you held the stock and how much other income you have. Stock held more than one year gets the long-term rates. Those rates are 0%, 15% or 20%, depending on where the gain lands on top of your other taxable income. A gain on stock held one year or less is taxed as ordinary income. High earners also add the 3.8% Net Investment Income Tax. The stock capital gains tax calculator below shows your gain, federal tax, surtax and proceeds after tax for 2026. In our internal calculation, we took a single filer with $85,000 of other taxable income. They sell stock bought for $30,000 for $50,000, which is a $20,000 gain. If they held it more than one year, the gain is taxed at 15%, so the tax is $3,000. If they held it one year or less, the same gain is taxed at 22% as ordinary income. That tax is $4,400. Holding past one year saves $1,400.

The typical homeowner pays $16,566 a year on top of the mortgage. That works out to about $1,380 a month for maintenance, property taxes and homeowners insurance. The figures come from the Zillow and Thumbtack release of October 22, 2026. Maintenance makes up about two-thirds of that total. The hidden cost of owning a home calculator below starts with those national typical amounts. Replace them with your own tax bill, insurance quote and maintenance reserve to see what owning costs you each month, each year and over five years. In our internal cost modeling, we ran a newer home that needs $3,000 a year of maintenance through the calculator. It keeps the typical $3,129 property tax bill and $2,266 insurance premium. Its hidden cost comes to $8,395 a year, or $699.58 a month. That is $8,171 a year below the national typical. Over five years at 3% yearly growth, the total is $44,570.
