What is indexed universal life, and is it right for you?

How an IUL works, what the caps and floors mean, and what to ask before you sign an illustration.

Key points
  • You are not invested in the market and you do not receive dividends. You receive a formula tied to the index, with a floor, commonly 0 percent, and a cap on how much of an up year you get.
  • The illustration, the page of numbers an agent shows you, is a projection at an assumed rate. It is not a promise, and on most designs the company can change the caps later.
  • Ask any agent recommending an IUL to also quote the equivalent term policy. If they will not, that tells you something.

Indexed universal life, or IUL, is permanent life insurance, built to last your whole life. It holds a cash value, money that builds up inside the policy. The interest added to that money is tied to a market index, usually the S&P 500.

It gets sold hard, sometimes to people who needed a term policy. It is a real product with real uses, and it is also the one where reading the paperwork matters most.

How it works

Your premium, the money you pay in, covers the cost of insurance, what the company charges to keep the coverage in place, and the policy expenses. What is left goes into the cash value.

Each year the company credits interest based on how the index moved, inside two limits.

  • A floor, commonly 0 percent, so a down year in the index does not by itself reduce your cash value.
  • A cap, a ceiling on the interest you can be credited, or a participation rate, which gives you only a share of an up year.

That is why a good year in the index may not show up in your cash value. Anything above the cap is not yours, and the charges came out first.

You are not invested in the market and you do not receive dividends. You receive a formula tied to the index.

What the illustration is and is not

The illustration is the page of numbers an agent shows you. It is a projection at an assumed rate. It is not a promise, and on most designs the company can change the caps later.

Ask for it run at the guaranteed minimum rate too, the lowest the company can credit, and compare. If the policy only works at the optimistic number, it is fragile.

The cost that grows

The cost of insurance inside the policy rises as you age. In the early years the cash value absorbs it easily.

If the cash value grew less than the illustration showed, or you stopped paying in, those charges can eat the account in the later years. The policy can then lapse, which means it ends and the coverage is gone. That is how these policies fail.

Paying in too little is the most common way an IUL goes wrong.

When it makes sense

  • You have already put the maximum into your retirement accounts and want another tax advantaged place for money.
  • You need permanent coverage and want more upside than whole life, another permanent policy, offers.
  • You own a business and are using it for a buy-sell or key person arrangement.
  • You will pay into it consistently for decades, not for three years.

When it does not

If the main need is protecting a young family on a limited budget, term insurance covers far more for far less. A term policy runs for a set number of years and holds no cash value.

Buying a small IUL instead of a large term policy is the classic mistake. The family is underinsured in exactly the years the risk is highest.

Ask any agent recommending an IUL to also quote the equivalent term policy. If they will not, that tells you something.

Common follow-up questions

Can I lose money in an IUL?

Index performance will not push your cash value below the floor, but policy charges can. That is a real way to end up with less than you paid in, especially in the early years or if you stop funding it.

Can I borrow from the cash value?

Yes, and the loan is not taxed as income while the policy stays in force. Unpaid loans reduce the death benefit, the money paid to the person you named when you die. A large loan on a struggling policy can trigger a lapse and a tax bill.

Is an IUL a retirement plan?

No. It is life insurance with a savings component. It should not replace a 401(k) match or an IRA. Fill those first.

How much should it pay?

The death benefit is what your family receives. Most final expense policies here run between $5,000 and $25,000.
