Indexed Universal Life Insurance Is Not for Everyone: Who Should Not Buy an IUL

IUL gets pitched to young professionals, families, business owners, retirees, and pretty much everyone in between. The message is always consistent: this product can solve your financial problems, provide market upside with downside protection, and generate tax-free retirement income. One product, all things to all people.

For most people, IUL is the wrong tool entirely.

Not because it’s fraudulent. Not because it can’t work for anyone. But because there’s a fundamental mismatch between how it’s sold and who it actually serves. And that mismatch shows up in the data. 

According to a 2021 study by Gottlieb and Smetters, published in the American Economic Review (1) and drawing on SOA and LIMRA persistency data, nearly 88% of universal life policies never pay a death benefit. That figure covers all universal life products, including IUL. 

And IUL was built specifically to fix the lapse problems of earlier UL products. It hasn’t. The chassis is the problem.

This article is a profile-by-profile look at the people who should not buy an IUL, the data that supports why, and a fair look at the narrow group for whom it might make sense. We’re not taking sides. We’re giving you the information you need to make a decision that actually fits your life.

Key Takeaways:

• IUL is built on a one-year renewable term chassis, meaning internal insurance costs rise every single year as the policyholder ages
• Nearly 88% of universal life policies (including IUL) never pay a death benefit, with 57% of permanent policies (particularly universal life) lapsing in the first 10 years
• IUL cannot endow and cannot be converted to reduced paid-up status, meaning premiums are required indefinitely
• The product demands a level of behavioral consistency over 30 to 40 years that most people, including the most disciplined, cannot sustain
• IUL is not compatible with Infinite Banking because it lacks the guaranteed, predictable cash value growth the strategy requires
• The narrow group IUL actually serves is sophisticated, high-net-worth individuals using it specifically for estate planning leverage

What IUL Actually Is, and Why the Chassis Matters

Indexed universal life insurance is a form of permanent life insurance where cash value growth is linked to a market index, typically the S&P 500. 

The policyholder isn’t actually invested in the market. The insurance company credits growth based on index performance, subject to a cap (the maximum you can earn) and a floor (usually 0%). You participate in some of the upside. You’re protected from direct index losses. That’s the pitch.

The One-Year Renewable Term Problem

The structural reality is different from the marketing version. Unlike whole life insurance, which spreads insurance costs evenly across a lifetime so the premium never changes, IUL is built on a one-year renewable term chassis. That means the cost of insurance increases every single year as the insured ages. In the early years, you barely notice. Over decades, and especially in retirement, it becomes a serious structural pressure on the policy’s cash value.

The flexible premium feature, often marketed as a benefit, is part of the same structural reality. Flexibility sounds good. But it means the policy requires ongoing management and can deteriorate if premiums are reduced or skipped. 

The policy doesn’t just sit there working for you. It demands attention, funding, and active monitoring year after year.

For a deeper look at the structural risks, internal charges, and illustration problems with IUL, see our posts on the dangerous truths about IUL risks and Todd Langford’s analysis of IUL math.

Who Should Not Buy an IUL Policy

This is the core question. Not “is IUL good or bad?” but “is the person buying it actually a match for what the product demands?” Seven profiles. If you recognize yourself in any of them, that’s information worth taking seriously.

Anyone who hasn’t mastered the financial basics

IUL is an advanced financial product. It should not be anyone’s first or second financial move. Before using a structure that combines insurance, investing, and tax planning, a person needs the basics in place: spending less than they earn, building consistent positive cash flow, and saving habitually.

Parkinson’s Law, the tendency for expenses to rise to meet income at every level, is real. IUL does not fix a cash flow problem. It adds complexity on top of one. If you haven’t overcome the basic discipline of keeping your income above your expenses and putting the gap into savings, a complex product isn’t a solution. It’s a distraction from the actual problem.

Anyone who needs guarantees and predictability

If you need to know with certainty what your policy will be worth in 10, 20, or 30 years, IUL cannot give you that. There is no guaranteed cash value dollar amount in an IUL. The crediting depends on index performance, caps that can change annually, and internal costs that increase over time.

If your financial planning requires a predictable future asset base for retirement, a major capital need, or a legacy strategy, a product built on variables is the wrong foundation. The middle class, upper middle class, and anyone with fluctuating income fall into this category. And that’s most people.

Anyone practicing or planning Infinite Banking

IUL is actively marketed as a vehicle for Infinite Banking. It is not. 

Infinite Banking requires a pool of capital that is predictable, guaranteed, and always growing. The arbitrage that makes policy loans powerful, earning in two places at once, only works when the policy’s growth is reliable.

In a year where the index earns zero, a policy loan doesn’t just cost the loan interest. It costs the loan interest with no offsetting policy growth. 

The banking system breaks down exactly when it should be working hardest. For a full breakdown, see our post on why IUL is incompatible with Infinite Banking.

Anyone without a high, stable, long-term income

IUL requires consistent, maximum funding over a very long time horizon to have any chance of performing as illustrated. Life disruptions like job changes, business downturns, family expenses, and medical costs interrupt premium payments. And because the policy relies on the index to help fund its own rising costs, any gap in funding creates a cascade effect that’s very difficult to reverse.

Even Nelson Nash, the creator of Infinite Banking, once missed funding PUAs on one of his own policies, causing the rider to close. If the creator of the strategy had trouble keeping up with premiums, the expectation that ordinary policyholders will fund an IUL perfectly for 30 to 40 years is unrealistic.

Anyone who cannot handle the lapse risk

Nearly 88% of universal life policies never pay a death benefit, and IUL is part of that picture. That number should stop anyone from considering this product and make them ask: why? 

The answer is structural. Rising internal costs, non-guaranteed crediting, and the behavioral reality of managing a complex financial product over decades.

And lapsing isn’t just losing the policy. When a policy lapses with outstanding loans and cash value above the cost basis (the total premiums paid), the gain is treated as taxable ordinary income in the year of lapse. That tax bill arrives at the worst possible time, often in retirement, when income is fixed and absorbing it is most painful.

Anyone who misunderstands what market risk means in an IUL

Many buyers hear “zero is your floor” and believe their money is protected from losses. This is technically true and practically misleading. The 0% floor only protects against index-linked losses. It does not protect against the internal drag of rising mortality costs, administrative fees, and hedging strategy expenses, all of which continue to come out of the cash value regardless of what the index does.

A zero-credit year is effectively a negative year once internal charges are factored in. And when markets perform poorly over multiple years, the insurance company’s cost of maintaining those hedges rises. They respond by lowering caps. Lower caps mean less upside potential. This cycle of poor performance, higher hedge costs, and lower caps compounds over time.

Anyone building a multi-generational legacy

Legacy planning requires certainty across decades and generations. A policy that cannot endow, cannot be converted to reduced paid-up status, and requires active management indefinitely is not a reliable foundation for generational wealth transfer.

Whole life policies endow at age 120 or 121. The cash value and death benefit converge, and the policy is contractually complete. IUL policies do not endow. Premiums are required for as long as the insured lives. There is no actuarial endpoint. 

For the Family Banking Formula and Seven Generations Legacy work we do at TMA, the guaranteed structure of whole life is not a preference. It’s a requirement.

The Data Nobody Shows You Before You Sign

LIMRA, the Life Insurance Marketing Research Association, has been tracking industry data for over 110 years. They have no stake in the IUL debate. Their numbers are the industry’s own.

The Headline Numbers

Nearly 88% of universal life policies never pay a death benefit. 57% of permanent policies (particularly universal life) lapse within the first 10 years. These aren’t TMA’s numbers. They come from a peer-reviewed study in the American Economic Review, drawing on SOA and LIMRA persistency data spanning decades. That is an extraordinary failure rate for a category of products marketed as cornerstones of financial planning.

A Pattern That Keeps Repeating

IUL was developed to solve the problems of regular universal life and variable universal life. Universal life was created in the 1970s when interest rates were rising. When rates fell, it stopped working. 

Variable universal life was the fix. When markets were volatile, VUL stopped working. IUL was the next fix. And universal life products as a category are still failing at 88%.

The pattern of “we tweaked it, it still doesn’t work” is worth naming for what it is: a structural problem with the chassis, not a problem that can be solved with another adjustment to the crediting mechanism.

Whole life also has surrender rates, but roughly a third lower. And a meaningful portion of whole life surrenders, according to LIMRA, occur because policyholders surrendered their whole life to purchase an IUL. Which means the actual organic lapse rate for whole life is lower still.

To Be Fair: Who IUL Actually Serves

IUL is not a scam. There are people who buy whole life who say it’s a scam. We are not saying that. We’re saying it’s a product that is systematically sold to the wrong buyers.

The Right Buyer Profile

The person IUL actually fits is a sophisticated, high-net-worth individual with high and stable income, substantial existing assets, a full understanding of the product’s risks, and the willingness and ability to fund the policy maximally for its entire life. That includes the potential to absorb significant premium increases in later years. This person is using IUL for estate planning leverage. Not for banking. Not for retirement income.

Bruce Wehner has sold approximately a dozen IUL policies in 15 years. All for estate planning. All to highly sophisticated clients. And always after attempting to talk the client out of it first. He documents every risk discussed in writing so clients can’t later say they weren’t warned. That’s how seriously the risks need to be taken, even for the small percentage of buyers for whom the product might actually work.

The problem is not that IUL exists. The problem is that it’s marketed to everyone as a one-size-fits-all solution, when the data shows it genuinely works for a very small percentage of buyers.

The Alternative Built for the Rest of Us

If the profiles above describe you, and statistically they describe the overwhelming majority of people being pitched IUL, the question becomes: what’s the alternative?

Why Endowment Matters

Whole life policies endow. The cash value and death benefit converge at age 120 or 121. This is not a technicality. It is the actuarial foundation that allows every whole life guarantee to exist. The guaranteed premium. The guaranteed cash value. The reduced paid-up option. All of it flows from the fact that the policy has a contractual endpoint.

IUL policies cannot endow because the cost of insurance keeps rising indefinitely. There is no actuarial endpoint, and that single fact is why none of the same guarantees can exist.

The Reduced Paid-Up Safety Net

If a whole life policyholder at any point can no longer pay premiums, or simply chooses not to, they can convert the policy to reduced paid-up status. The death benefit is reduced, no further premiums are required, and the policy remains in force for life. 

This option does not exist with IUL. IUL policyholders must pay premiums indefinitely. There is no off-ramp that preserves the policy without continued funding.

Behavioral Fit

Whole life’s level premium creates discipline by design. The premium is the same every year, forever. The policy does not require the policyholder to manage crediting rates, monitor cap changes, or increase contributions as they age. 

Simplicity is not a weakness. It’s what makes the strategy work across the full range of human behavior over decades.

The Decision Is Yours: Make It With the Full Picture

IUL is not a scam. It’s a product that works for a very specific buyer. The question is whether that buyer is you.

Before signing anything, ask yourself three questions:

Do I have the financial basics in place, with positive cash flow, consistent savings, and no dependence on this policy to fill gaps? 

Can I absorb a significant premium increase 15 to 20 years from now without disrupting my financial life? 

Do I fully understand the crediting mechanism, the cap structure, the hedging costs, and the lapse risk, not just the illustrated projections?

If the answer to any of those is unclear, that’s important information. And the conversation with an agent who is trying to sell you this product is not the place to get that clarity.
