Indexed Universal Life Insurance Pros and Cons
Indexed universal life insurance (IUL) is permanent life insurance whose cash value earns interest tied to a stock index. Every guide we write here starts from the math, and on an IUL the math turns on charges more than on the index. Gains are capped. A 0% floor keeps an index drop from cutting the credited rate, and the policy's own charges come out either way.
For most readers, an IUL is the wrong home for retirement money. Fill an employer match and a Roth account first. Indexed universal life insurance earns its place in a narrow set of situations, and every one of them starts with a permanent need for a death benefit.
How Indexed Universal Life Insurance Credits Interest
An IUL credits interest based on the movement of a stock index, and your money never goes into that index. The insurer holds the cash value in its own general account. You own a contract with the carrier, so you receive no shares and no dividends.
The cap sets the most a segment can earn in a crediting period, however far the index climbs. The participation rate sets what share of the index gain counts before the cap applies. A floor, usually 0%, stops an index decline from pushing the credited rate below zero.
Most IUL products track the price return of an index such as the S&P 500, which measures price change alone. Dividends paid by the companies in that index sit outside the measure. Over a long holding period those dividends make up a large share of the index's total return, and an IUL credits none of them.
The floor protects the credited rate. It does not protect the account balance. A year credited at 0% still has cost-of-insurance charges, administrative fees, and any rider charges deducted from cash value. The balance can fall in a year the policy earned nothing.
Cost of Insurance Charges Rise Every Year You Age
Cost of insurance (COI) is the charge your insurer deducts from cash value each month to pay for the death benefit, and its rate climbs as you get older. The Wisconsin Office of the Commissioner of Insurance states it plainly: as you age, the rate of the cost of insurance charge will increase.
That rising charge is the mechanism behind most universal life lapses. A policy funded at or near the minimum premium builds only a thin cash value in the early years. Decades later the monthly deduction is a multiple of what it was at issue, and the thin cash value cannot absorb it. The owner then gets a demand for a much larger premium, or a lapse notice.
Wisconsin's regulator describes exactly that pattern. Owners paid for years believing their premium would not change. Many then found the policy had lapsed with little or no value, or were told to pay large additional premiums to keep the coverage.
Overfund the policy and this does not happen. Pay well above the minimum so cash value stays ahead of the charges. Ask your insurer every year for a free in-force illustration and for the premium that keeps the policy going to age 100. Ask that question and you will find the shortfall while you can still fix it with money instead of losing the coverage.
Why an Illustrated Rate Is Not a Promise
An IUL illustration shows what the policy would do if a chosen crediting rate repeated for decades, and no carrier guarantees that rate will happen. The National Association of Insurance Commissioners (NAIC) limits what those projections may show through Actuarial Guideline XLIX-A, which covers index-based policies sold from December 2020 onward. The NAIC tightened its illustration limits in 2023 and added consumer disclosures in 2026.
A cap can also move after you buy. The Financial Industry Regulatory Authority (FINRA) notes that some indexed annuity contracts let the issuer change fees, participation rates, and interest caps from time to time. Indexed life products are built on the same crediting design. Read your own contract to see which terms the insurer may redeclare and what the guaranteed minimums are.
Ask for two illustrations before you sign: one at the rate the agent proposes, and one at the policy's guaranteed minimum crediting rate with the maximum contractual charges. The second version shows the worst outcome the contract permits. If that version lapses in your seventies, the plan only works while the non-guaranteed numbers hold. Our guide to IUL illustrations by carrier works through exactly how that guaranteed-versus-illustrated gap looks on the specific carriers people search for by name.
Why a 7702 Plan Is Not a Retirement Account
A 7702 plan is a marketing name for a cash-value life insurance policy, and no such account exists in the tax code. Section 7702 of the Internal Revenue Code sets the test a contract must pass to be treated as life insurance for tax purposes. The Legal Information Institute publishes the text of that statute. It draws a boundary around what counts as insurance. It does not create an account you can open with the Internal Revenue Service (IRS).
Passing that test earns the tax treatment sellers describe. The IRS says life insurance proceeds a beneficiary receives on the death of the insured are generally not includable in gross income. Cash value also grows without an annual tax bill while it stays inside the policy. A contract that fails the section 7702 test loses that treatment, and the income inside it becomes taxable.
There is a second boundary further in. Pay premiums too quickly in the early years and the policy becomes a modified endowment contract (MEC) under section 7702A, which changes how loans and withdrawals are taxed. Our guide to borrowing against life insurance works through MEC treatment and the tax bill a lapsed policy loan creates.
For a buyer, the label carries no information about price. "7702 plan" tells you nothing about the cap, the charges, or the premium the policy needs. The same product is also sold as a tax-free retirement account, so ask which contract you are being offered and price it as insurance.
Indexed Universal Life Insurance Pros and Cons
The case for indexed universal life insurance is a permanent death benefit paired with tax-deferred cash value and no annual contribution limit. The case against it is cost, and that cost is not fixed at purchase.
Coverage lasts for life, so a lifelong obligation stays covered instead of expiring at the end of a term. The 0% floor means an index decline does not cut the credited rate. The IRS sets no contribution cap on a life insurance policy, so a high earner who has already maxed every tax-advantaged account still has somewhere to put money. Premiums flex, so you can pay more in a strong year.
Against that, COI charges rise with age and come straight out of cash value. The insurer can lower the cap and the participation rate on a policy already in force. The index pays dividends your policy never credits. Surrender charges in the early years mean an early exit returns far less than the statement balance suggests. Comparing two IUL policies takes a full illustration from each carrier rather than a rate sheet.
Nearly everyone publishing about IUL also sells it. When we read the pages currently ranking for indexed universal life insurance, all but one belonged to a company in that business, including Nationwide, Guardian Life and Transamerica. Investopedia was the exception. A pros-and-cons list written by a seller tends to be accurate on the mechanics and quiet on the charges, including how much of the first-year premium the selling agent keeps — see our guide to how IUL agent commission works for that number.
How an IUL Compares to a 401(k) or Roth IRA
A 401(k) and a Roth individual retirement account (IRA) beat an IUL on cost for the same dollar, because neither one charges you for a death benefit. Employer matching money is an immediate return no insurance policy can match, and index funds inside those accounts receive dividends and face no cap.
The IUL advantage is narrow and real. There is no annual contribution limit, so someone who has already filled a 401(k) and a mega backdoor Roth still has room. The death benefit also passes to a beneficiary generally free of income tax, which a traditional retirement account does not.
Run both sides before you commit money. Our 401(k) calculator and Roth IRA calculator show what the same annual premium would do inside a tax-advantaged account over the same years. For the full head-to-head, see IUL vs 401(k) and IUL vs Roth IRA. If you are weighing IUL against whole life instead, whole life vs universal life insurance sets out which guarantees each contract gives you.
Who Indexed Universal Life Insurance Fits
An IUL fits someone with a permanent death benefit need and every tax-advantaged account already maxed. It also takes the cash flow to fund the policy well above its minimum premium for life. That usually means a high earner holding coverage for estate or business-continuity reasons. It can also mean a parent providing for a child with a disability who will need money after both parents are gone.
It does not fit a reader buying it as a retirement plan. If your employer match is unfilled, your Roth IRA is not maxed, or your emergency fund is thin, those come first and the gap is not close. Term life covers the years your family depends on your income for a small fraction of the premium. Our guide on how much life insurance you need sizes that coverage, and whole life vs term life insurance covers the permanent-versus-temporary decision.
It also does not fit anyone who might stop paying. An IUL funded at the minimum and abandoned in year six returns very little, and the coverage goes with it. The same contract is sold under other names, including infinite banking and private placement life insurance, so the same funding discipline applies to each.
What Would Change Our Answer
Two product changes would move indexed universal life insurance up our list. The first is a contract that guarantees the cap instead of letting the insurer redeclare it, because the cap decides whether the credited rate ever covers the charges. The second is a policy that guarantees COI rates at the current scale for life rather than at a higher contractual maximum.
A tax change would do it too. If Congress cut the contribution room in 401(k) and Roth accounts, the absence of a limit on a life insurance policy would matter far more.
Until one of those happens, treat indexed universal life insurance as an insurance purchase first. Ask any carrier you are considering for an illustration run at the guaranteed minimum. Then compare that indexed universal life insurance quote against term coverage plus the same money in a Roth IRA.
Frequently asked questions
How much money do you need to start an IUL?
Each carrier sets its own minimum premium, and no law sets one, so the figure varies by insurer and by the death benefit you apply for. The number that matters more is the premium that keeps the policy funded above its charges for life, which is well above the minimum the carrier will accept. Ask for both figures in writing, and fund toward the second one.
How much does a $1,000,000 life insurance policy cost per month?
The premium depends on your age, health, tobacco use, and whether you buy term or permanent coverage. Quotes for the same $1,000,000 death benefit vary widely between two applicants. A $1,000,000 term policy costs a small fraction of a $1,000,000 IUL, because the term policy builds no cash value and covers only a set number of years. Get quotes from several carriers on identical coverage before comparing, and use our life insurance needs guide to check whether $1,000,000 is the right amount for you.
Which one is better, IUL or 401(k)?
A 401(k) is better for retirement saving for almost everyone, mainly because of the employer match and the absence of insurance charges. An IUL only becomes worth considering after the 401(k) is maxed, a Roth is maxed, and you still have a permanent death benefit need. See IUL vs 401(k) for the side-by-side numbers.
What does Dave Ramsey say about indexed universal life insurance?
Ramsey Solutions advises against IUL, calling it a poor wealth-building tool because of its fees and its capped returns. Their published recommendation is to buy term life insurance for income replacement and invest separately in growth stock mutual funds. Their objection is to combining insurance with investing in one contract, the same structural point the cost-of-insurance math makes.
What are the downsides of indexed universal life insurance?
The main downside is cost-of-insurance charges that rise every year you age and are deducted from cash value, which causes underfunded policies to lapse decades in. Beyond that, the insurer can lower your cap and participation rate after you buy. Index dividends never reach your policy, and surrender charges in the early years make an early exit expensive. The illustration you are shown at purchase is a projection under a non-guaranteed rate, so ask for one run at the guaranteed minimum as well.
What does Suze Orman recommend for life insurance?
Suze Orman recommends term life insurance and keeping insurance separate from investing. She describes term as cheap, with "no investing angle to it," and warns that fees inside a cash-value policy run higher than a low-cost index fund or exchange-traded fund (ETF). She and Ramsey Solutions give the same advice: buy term, and invest the difference elsewhere.
