Business Loan Payoff Calculator
A business loan payoff calculator shows how much faster you can clear a standard term loan — like an SBA 7(a) or bank loan — by adding extra money to your monthly payment. Enter your remaining balance, rate, remaining term, and any extra amount in the calculator above.
For example, a $100,000 balance at 9.5% APR with 60 months left pays off 9 months sooner and saves $4,187 in interest with a $300 extra payment each month.
How it works
This calculator rebuilds your loan's amortization schedule — the same month-by-month breakdown your lender uses. Each month, interest is charged on your remaining balance first, and the rest of your payment reduces principal. Because interest is calculated on a shrinking balance, applying extra money to principal today reduces every future interest charge, not just the current one.
Pick your goal above the calculator. "I can pay extra each month" compares your original schedule to that same payment plus a fixed extra amount, showing the months and interest you save. "I want a payoff date" works backward instead: tell it how many months until you want to be debt-free, and it solves for the exact extra monthly payment that gets you there. This is a standard amortizing-loan calculation — it does not apply to a merchant cash advance or invoice factoring, which are priced by a fixed factor rate instead of an annual interest rate; see our merchant cash advance calculator for that math.
Before sending extra principal, confirm two things with your lender in writing: that extra payments are applied to principal (not just credited toward next month's payment), and that your loan has no prepayment penalty. SBA 7(a) loans over $500,000 with a term of 15+ years, and many bank term loans in their early years, sometimes carry one.
Frequently asked questions
How does a business loan payoff calculator work?
It rebuilds your loan's amortization schedule month by month, charging interest on your remaining balance first and applying the rest of the payment to principal. Adding a fixed extra amount every month is applied straight to principal, which shrinks the balance faster and lowers every future month's interest charge. Switch to "I want a payoff date" if you'd rather work backward from a target timeline to the required payment.
Does paying extra on a business loan always save money?
On a standard amortizing loan (fixed rate, interest charged on the declining balance), yes — extra principal payments always reduce total interest, as long as your lender applies the extra to principal rather than future payments and there's no prepayment penalty. Confirm both with your lender before paying extra.
What's the difference between this and a merchant cash advance payoff?
A term loan charges interest on your declining balance, so paying early genuinely reduces the total cost. A merchant cash advance uses a fixed factor rate applied once to the full advance, so the total payback is generally fixed regardless of timing. Use the merchant cash advance payoff calculator for that math instead.
Should I pay off my business loan early or invest the extra cash?
Compare your loan's interest rate to your realistic after-tax return on alternative uses of that cash. If your loan rate is higher than what you'd confidently earn elsewhere, paying it down is the safer, guaranteed return. If your rate is low and the business has a strong growth use for the cash, reinvesting may win — run both scenarios before deciding.
What should I check before making extra payments on a business loan?
Four things: whether your lender has a prepayment penalty, whether extra payments are applied to principal (get this in writing), whether you're keeping enough cash reserve for payroll and emergencies before sending extra money to the loan, and the loan's tax treatment — interest on a business term loan is generally deductible as a business expense, so paying it off faster also shrinks that deduction going forward.
