Indexed Universal Life Insurance Explained for Working Families

An IUL is permanent life insurance whose cash value earns index-linked interest, capped on the upside and floored at 0%, while policy charges come out every month.

Indexed universal life insurance (IUL) is permanent life insurance with a cash value account that earns interest tied to a stock index, usually the S&P 500, with a cap on the upside and a 0% floor on the index credit. Every month the insurer deducts the cost of insurance and other charges from that account before any interest is credited, which is why an IUL can lose cash value in a flat year even though the index credit cannot be negative. This guide covers where each premium dollar goes, the three dials, what the carrier can change, loans and lapse, funding levels, cost next to term, illustrations under AG 49-A, and who it fits.

Key takeaways

• An IUL is a universal life policy whose interest credits follow an index such as the S&P 500; FINRA says it “is generally not considered a security,” so state insurance departments regulate it, not the SEC (FINRA).
• The 0% floor applies to the index credit only. Cost of insurance, policy fees and rider charges come out every month regardless, so cash value can fall in a down year and an underfunded policy can lapse (National Life; Texas Department of Insurance, December 2025).
• Caps, participation rates and spreads are non-guaranteed elements; the NAIC advertising model requires disclosure that the insurer “reserves the right to change any such element at any time and for any reason” (NAIC Model 570, 2015).
• Policy loans need no credit check, accrue interest and are subtracted from the death benefit if unpaid; a lapse with a loan outstanding can make the policy’s gain taxable (NAIC; IRS Publication 525, 2025).
• A critic who sat through a pitch puts IUL at 10 to 20 times the cost of term for the same death benefit; for scale, a $500,000 20-year term policy averaged $32.21 a month for a 35-year-old male in October 2025 (White Coat Investor; Policygenius).
• Under AG 49-A the illustrated rate on the benchmark S&P 500 account cannot exceed the lesser of a 25-year lookback average and 145% of the insurer’s net earnings rate, and policies sold on or after April 1, 2026 must show an Alternate Scale ledger with equal prominence (NAIC AG 49-A, adopted December 11, 2025).

What is indexed universal life insurance, in plain words?

Indexed universal life is a universal life policy, meaning a death benefit, flexible premiums and an account value, where the interest credited to the account follows a stock index instead of a rate the insurer sets. It has been sold since 1997 (Wikipedia). The NAIC’s Actuarial Guideline 49-A defines the reference design, the “Benchmark Index Account,” as one credited on “the percent change in S&P 500 Index value only, over a one-year period” with “an annual cap” (NAIC AG 49-A). Dividends paid by the companies in the index are generally not part of the credit (Policygenius).

New IUL policies brought in a record $4.5 billion of premium in 2025, and NerdWallet, citing LIMRA, ties part of that to social media clips that “only tell half the story” (NerdWallet). This article is the other half. For what coverage a tradesperson needs first, start with the guide to life insurance for blue collar workers.

Where does each premium dollar go?

Each premium dollar pays the policy’s charges first, and only what is left reaches the cash value to earn an index credit. FINRA describes the mechanism: for universal life, the cost of insurance and other costs are deducted from the policy account value (FINRA), and a carrier explainer footnotes that the monthly policy fee, expense charge, cost of insurance and rider charges are deducted regardless of the interest credited (National Life). The example figures below are one critic’s published schedule for one policy, not an industry price list (Personal Finance Club).

Charge	What it is	One published example
Premium expense charge	A percentage taken off every premium before it reaches the account	6% of each premium
Monthly policy fee	A flat administrative charge	$12 a month
Per-thousand expense charge	Based on the death benefit, heaviest in the early years	$0.59 a month per $1,000 of death benefit
Cost of insurance (COI)	The price of the pure death benefit, set by age, sex, health and rating class; it rises every year you age	Rises with age; no single figure
Index account charge	A charge on money in the indexed account	0.06% a month
Rider charges	Charges for riders the carrier prices	Varies by rider
Surrender charge	Charged if you cancel or withdraw heavily in the early years	Typically 10 to 15 years (Ethos)
Withdrawal fee	A fee on partial withdrawals	$25 per withdrawal

Two rows explain most of the regret posts on trade forums: the front-loaded premium and per-thousand charges keep cash value thin for years, and the cost of insurance rises with age, so a policy funded at the minimum in your 30s faces charges in your 60s that a thin account may not cover. A roofer or a lineman in a higher rating class pays more cost of insurance inside an IUL, just as with term (see does your job make life insurance more expensive).

How do the cap, participation rate and floor work?

Three dials decide how much of an index move reaches your cash value: the cap is the most you can be credited in a period, the participation rate is the share of the index change that counts, and the floor is the least you can be credited, 0% on most policies. A carrier explainer states both ends: “the least interest you are ever credited is 0%” and “The cap determines the maximum interest you can earn in a period” (National Life). Some policies also subtract a spread from the index change before crediting.

Dial	Worked example (sourced)	Credited
Cap	Index up 10%, cap 6% (National Life)	6%
Cap in a modest year	Index up 8%, cap 4% (Policygenius)	4%
Participation rate	Index up 8%, participation 60% (National Life)	4.80%
Participation rate, more examples	Index up 10% at 80% (Policygenius); index up 10% at 50% (Forbes Advisor)	8%; 5%
Participation above 100%	Index up 8%, participation 140%, usually paired with a lower cap or an account charge (National Life)	11.20%
Floor	Index down 15% in a year with a 0% floor	0%, and every month’s charges still come out

Why “your cash value only moves up” is false

The 0% floor protects the index credit, not the account. In a year the index falls, the policy credits 0% and the cost of insurance, policy fee and expense charges are still deducted every month, so cash value goes down by the amount of those charges. The Texas Department of Insurance adds that if a universal life policy’s cash value reaches zero, the policy could lapse (Texas DOI, December 2025). The honest sentence: interest credited from the index cannot be negative, but policy charges are still deducted, so cash value can fall. A pitch that leaves off the second half describes a product that does not exist.

A 0% year in an IUL is not a zero year: the index credits nothing, and the charges still come out.

What can the carrier change after you sign?

The carrier can lower the cap, lower the participation rate, widen a spread and raise the cost of insurance up to the contract maximum, all after you sign, because each is a non-guaranteed element. The NAIC advertising model defines nonguaranteed elements as premiums, credited rates, charges and formula elements “that are subject to company discretion,” and requires any ad that mentions one to say the insurer “reserves the right to change any such element at any time and for any reason” (NAIC Model 570, 2015). What cannot move is the set of guaranteed elements printed in the contract: the guaranteed minimum interest rate, the maximum charges, and the death benefit so long as the policy is funded on its terms.

Policygenius shows the squeeze: an 8% S&P year under a 4% cap credits 4%, and critics note caps can drop after purchase (Policygenius; Forbes Advisor). The owner’s defense is the annual in-force illustration. Texas’s Office of Public Insurance Counsel tells universal life owners to “Review your policy every year” and “Ask for an ‘inforce illustration’” because “you may need to adjust your premiums to avoid losing your death benefit or cash value” (Texas OPIC).

How do IUL policy loans work, and how does a policy lapse?

A policy loan lets you borrow from the insurer against your cash value with no credit check; interest accrues, and any unpaid balance plus interest is subtracted from the death benefit (MoneyGeek; NAIC). Designs vary: one carrier’s help page describes a fixed participating loan at “a fixed loan rate of 5%” where the loaned money keeps earning index credits, a variable-rate loan, and a “wash loan” where the rate charged equals the rate credited (National Life). Terms differ by carrier, product and state.

Policy loans and withdrawals up to basis are generally not subject to income tax while the policy stays in force and is not a modified endowment contract (MEC). If the policy lapses or is surrendered with a loan outstanding, the loan is repaid from the cash value and, in the IRS’s words, “you must include in income any proceeds that are more than the cost of the life insurance policy,” even though you receive no cash (IRS Publication 525, 2025). Cash value grows tax-deferred while the contract qualifies as life insurance, and the death benefit is generally income-tax-free to beneficiaries under 26 U.S.C. 101(a).

How a lapse happens:

1. Charges outrun credits: cost of insurance rises with age, a down year credits 0%, and a loan balance compounds.
2. The insurer’s annual report estimates how long the policy may last (Texas DOI).
3. Cash value hits zero, a premium comes due, and the usual 31-day grace period runs out.
4. Reinstatement is usually possible within five years with back premium, interest and possibly health questions.
5. If there was a loan and a gain, the gain is taxable in the year of the lapse (IRS Publication 525).

Some carriers offer an overloan protection rider that turns a heavily borrowed policy into paid-up insurance. New York’s regulator notes a typical condition of “usually 15 years” in force and requires the warning that “Neither the IRS nor the courts have ruled on the tax consequences of exercising the overloan protection rider” (NY Department of Financial Services, 2013).

What do minimum, target and maximum funding mean?

Minimum funding pays just enough premium to cover current charges, target funding pays the premium the carrier’s illustration shows carrying the policy to maturity at its illustrated rate, and maximum funding pays as much as the tax code allows for that death benefit without crossing the MEC line. This design choice is behind most of the horror stories.

• Minimum funded: the lowest premium that keeps the policy alive today, usually stretched across the largest death benefit it can carry. Cash value stays thin and the rising cost of insurance eats it later; the NAIC warns, “If you take cash value out, there may not be enough to pay premiums” (NAIC). It is how $400 a month and about $11,000 paid in ends as roughly $2,000 of surrender value, as one family member described on r/personalfinance (r/personalfinance).
• Target funded: the illustration’s premium, which holds only if the illustrated rate holds and the cap is not lowered, so it needs an in-force illustration every year.
• Funded toward the MEC line: the most premium the policy can take. Under 26 U.S.C. 7702A a policy becomes a MEC if premiums paid in the first seven years exceed seven level annual premiums that would pay it up (the 7-pay test). Below the line, charges are a smaller share of the account and cash value builds faster. Cross it and loans and withdrawals are taxed income-first with a 10% additional tax before age 59 1/2 (26 U.S.C. 72). Raising the death benefit later restarts the 7-pay test.

Even a maximum-funded policy carries real insurance: under the guideline premium test the death benefit must stay at or above a set percentage of cash value (26 U.S.C. 7702). An independent licensed agent can run all three funding levels on the same death benefit; check what you qualify for in about a minute and ask for exactly that.

What does an IUL cost compared with term insurance?

An IUL costs many times what term costs for the same death benefit, because the premium funds a cash value account and a policy expected to pay out, not a limited period of risk. The reference point: a $500,000, 20-year term policy for a 35-year-old male non-smoker averaged $32.21 a month across 13 carriers as of October 1, 2025, and $43.52 at age 40 (Policygenius Price Index, published February 2026). There is no public price index for IUL; premiums are flexible within contract limits, so any “average IUL costs $X a month” claim has no source.

What critics publish, with the caveat that they are critics: a physician who declined a pitch reports IUL often costs 10 to 20 times a term policy for the same death benefit, first-year fees of 50% to 100% of first-year premium, break-even typically 10 to 15 years and loan interest of about 5% to 6% (White Coat Investor). Personal Finance Club’s model of $200 a month for 40 years, which assumes a 13.75% cap and gives the death benefit no value, shows 16 years before cash value returns the premiums paid and total fees of $78,729 (Personal Finance Club; the author sells investing courses). The NAIC’s consumer page says it plainly: “It may be very costly if you quit during the early years of the policy” (NAIC).

An IUL sits beside a 401(k) or a pension; it does not replace either. The trade-offs are in IUL vs 401(k), Roth IRA and pension, and the critics’ full case, where it is right and where it is sloppy, is in the honest answer to the objection discourse.

What is an IUL illustration, and what does AG 49-A require?

An illustration is a carrier-generated projection of premiums, charges, cash value and death benefit at an assumed crediting rate; it is not a prediction, a quote or a promise. The NAIC illustration model bars implying that non-guaranteed elements are fixed, bans the phrase “vanishing premium” and bans lapse-supported illustrations (NAIC Model 582).

The rules exist because illustrations ran hot. In December 2014 three large insurers cited a Kansas Department of Insurance survey showing most IUL policies illustrated above 7%, with a median above 8% (InsuranceNewsNet, December 2014). AG 49 arrived in 2015, and InvestmentNews reports average illustrated rates fell from 7.3% in August 2015 to 6.35% a few years later (InvestmentNews). AG 49-A replaced it for policies sold on or after December 14, 2020 and was revised again on December 11, 2025 (NAIC Center for Insurance Policy and Research, January 2026). Today it does three things:

1. Caps the illustrated rate. On the benchmark S&P 500 account the illustrated credit cannot exceed the lesser of the 25-year historical lookback average and “145% of the Annual Net Investment Earnings Rate” of the insurer’s general account (NAIC AG 49-A, Sections 3.B and 4.B). One actuary’s backcast for a 2026 illustration puts that ceiling near 5.84% at a 9% cap and 6.83% at an 11% cap, an estimate of a ceiling, not a return (actuary.info, October 2026).
2. Limits the loan math. The rate credited on loaned money may exceed the loan rate by no more than 50 basis points, down from 100 under the 2015 version (Section 6). That retired the “borrow at five, earn at seven” slide.
3. Adds disclosures for policies sold on or after April 1, 2026: an Alternate Scale ledger “alongside the ledger using the illustrated scale with equal prominence,” a table of minimum and maximum 25-year lookback rates, a 25-year table of actual index changes, and the sentence “Historical index changes shown in this illustration are not indicative of future returns” (Section 7).

How to read one: find the guaranteed elements column (minimum interest rate, maximum charges), because that is the only page the carrier has signed; treat the illustrated column as the best the policy will ever look on paper; and ask for a rerun one or two points under the maximum rate with the cap lowered, since the carrier can do both after issue.

Who does an IUL fit, and who should pass?

An IUL fits a person who needs permanent coverage, wants accelerated benefit riders attached to it, and can fund the policy at or near target through slow months for 15 years or more without shorting a matched retirement plan. It does not fit a person who needs the most coverage per dollar today, who may stop paying through a winter, or who was told it is a retirement account.

It tends to fit when there is a permanent need (a lifelong dependent, a business buyout, a death benefit meant to pay whenever death comes); when living benefits matter, since accelerated benefit riders may let you access part of the death benefit after a qualifying illness or injury, with terms, triggers and availability varying by carrier and state and acceleration reducing the death benefit (they are not disability insurance and do not pay for an ordinary job-site injury; see living benefits life insurance explained); when the premium clears a January layoff or a strike, because a minimum-funded policy is the design that fails; and when surrender charges of 10 to 15 years (Ethos) and a critic’s 10 to 15 year break-even (White Coat Investor) fit the holding period.

It does not fit when the need is income replacement for 20 or 25 years on a tight budget, which level term does at a fraction of the price, including no-exam term for most dangerous jobs (no-exam life insurance for dangerous jobs); when the pitch used “investment,” “savings plan” or “private pension,” words the NAIC advertising model bans for a life policy because they mislead (NAIC Model 570, Section 4.B); when nobody depends on your income; or when nobody has shown you the guaranteed elements column and the charge schedule.

If a permanent policy is on the table, check what you qualify for in about a minute, then ask the independent licensed agent for the rerun under the maximum rate, the guaranteed elements column and the charge schedule in writing. Blue Collar Workers Covered is not an insurance company and not a licensed insurance agency; it connects consumers with independent licensed insurance agents, who provide all quotes, advice and coverage (how Blue Collar Workers Covered works).

Frequently asked questions

Can you lose money in an IUL?

Yes. Charges are deducted every month whether or not the index credits anything, so in a flat or down year cash value falls by the amount of those charges, and surrender charges in the first 10 to 15 years mean cashing out early returns less than you paid (National Life; Ethos). A lapse with a loan outstanding can add a tax bill on the gain (IRS Publication 525).

What happens if I stop paying IUL premiums?

The policy keeps drawing its monthly charges from the cash value until it runs out, then enters a grace period, usually 31 days, and lapses if the premium is still unpaid (Texas DOI, December 2025). A well-funded policy can coast through a slow season; a minimum-funded policy has little to coast on. Reinstatement is usually possible within five years with back premium, interest and possibly health questions.

Is IUL better than whole life?

Neither is better in general; they trade certainty for flexibility. Whole life has level premiums, a guaranteed cash value schedule and a guaranteed death benefit, which is part of why a $500,000 policy averaged $706 a month for a 40-year-old male as of October 2024 (Policygenius). IUL has flexible premiums and index credits with caps and participation rates the carrier can change, so it must be watched with in-force illustrations.

What is a cap rate in IUL?

A cap rate is the maximum interest the policy will credit for a crediting period, however far the index rises. If the index gains 10% and the cap is 6%, the policy credits 6% (National Life). The cap is a non-guaranteed element, so the carrier can lower it after issue; the cap quoted at sale is not the cap for life (NAIC Model 570).

Can my cash value go down in an IUL?

Yes. The 0% floor stops the index credit from being negative, but the cost of insurance, policy fee, expense charges and rider charges are deducted regardless, so cash value can fall in any year the charges exceed the credit (National Life; FINRA). If cash value reaches zero, the policy could lapse (Texas DOI).

Life insurance products are offered through independent licensed agents; product features, riders and availability vary by carrier and state. Cash value growth in an indexed universal life policy is not guaranteed, policy charges apply, and policy loans and withdrawals reduce the cash value and death benefit and may have tax consequences.
