Indexed universal life, explained honestly

Online, IUL is either the answer to everything or something nobody should ever buy. Neither helps you decide. This guide explains the moving parts plainly, so you can judge a policy on its own terms.

The parts of a policy

An IUL policy has four working parts:

• A death benefit, paid to your beneficiaries, less any loans outstanding.
• Premiums that are flexible within limits. Paying more than the minimum is what builds cash value; paying too little is how policies get into trouble.
• A cash value, held in one or more index accounts and usually a fixed account that earns a declared rate.
• Charges, deducted every month whatever the index does.

One point is easy to miss: your money is never invested in the index. The insurer uses the index only to calculate how much interest to credit. That is why a falling market is not credited as a loss, and also why the policy does not receive the market’s full gains.

How the interest credit works

Most index accounts look at the index’s change over a crediting period, often one year, and then apply three terms. Some apply a fourth, a spread.

The cap

The cap is the most interest that can be credited in a period. If the index rises 18% and the cap is 10%, the account is credited 10%. Insurers can change caps on existing policies, within limits stated in the contract, so the cap you start with is not the cap you will always have.

Some index strategies are uncapped: there is no limit on the credit in a strong year. In exchange they usually credit a smaller share of the gain, through a lower participation rate, or take a spread off the gain first.

The participation rate

The participation rate is the share of the index’s gain that counts, before any cap applies. At 100%, the whole gain counts up to the cap. At 80%, a 10% rise counts as 8%.

The floor

The floor is the least that can be credited, often 0%. Some policies have a floor a little above zero, such as 0.75%. In a year the index falls, the account is credited the floor rather than a loss. The floor protects the interest credit. It does not stop the charges, so in a year credited at the floor the cash value can still go down.

Other features

A spread is a fixed percentage taken off the index’s gain, often in place of a cap. With a 5% spread, a 12% rise is credited 7%. Some policies offer bonuses or multipliers that raise the credit, usually in exchange for an extra charge. Ask what each feature costs, not only what it adds. Index crediting also follows the index’s price change, so the dividends that an index fund would collect are not included.

Assume a cap of 10%, a participation rate of 100% and a floor of 0%.

Index change in the year	Interest credited	Why
Up 15%	10%	The cap limits it
Up 6%	6%	Below the cap, so the full gain counts
Down 12%	0%	The floor applies

In every one of these years, including the year credited at 0%, the policy’s charges still come out.

The charges, and why they matter most

Crediting terms get most of the attention, but charges decide whether a policy works. The main ones are:

• Premium charges, a percentage of each payment.
• The cost of insurance, a monthly charge for the death benefit. It is based on your age, health and the amount of coverage, and it rises as you get older.
• Policy and administrative fees, often a flat monthly amount.
• Rider charges for any added benefits.
• Surrender charges if you end the policy in its early years, often for 10 to 15 years.

Because the cost of insurance rises with age, a policy that is not funded well can need much higher premiums later, or lapse. The trouble tends to build quietly: a few low-credit years, premiums paid at the minimum, and charges that slowly outgrow the cash value. A yearly review catches it while there is still time to adjust.

Reading an illustration

An illustration is the insurer’s projection for a specific policy, age, health rating and premium. Regulatory rules limit the rates it may assume, but it is still a projection, not a promise. When you review one:

• Read the guaranteed column, which shows the policy at the minimum credit and the maximum charges, as well as the illustrated one.
• Ask to see the policy at a lower crediting rate than the maximum the insurer may illustrate, and check that it still holds up.
• Look at the year-by-year cash value after surrender charges, not only the long-run total.

Loans and withdrawals

You can use the cash value through policy loans or withdrawals, beginning as early as policy year 3, for example to supplement income in retirement. Loans are borrowed from the insurer with the cash value as collateral, and interest accrues on them. Both loans and withdrawals reduce the death benefit.

You may hear policy loans described as tax-free income. They can be, but only while the policy stays in force and is not a modified endowment contract (MEC), a policy funded faster than federal limits allow. If the policy lapses or is surrendered with a loan outstanding, the gain can become taxable all at once. The death benefit itself is generally paid free of income tax, less any loans.

Who IUL can suit, and who it rarely suits

IUL can make sense if you:

• Need life insurance for the rest of your life, not just for a set number of years
• Want a guaranteed supplemental income at zero tax liability in retirement. A 401(k) is not a test to qualify: it is a separate bucket of money, and we still encourage contributing enough to get your employer’s full match
• Can fund the policy: for as little as 2 years when contributing the absolute maximum (the 7-pay limit), or with a regular premium for as long as you choose. We encourage funding for 15 years so the policy is fully endowed
• Want cash value you can borrow against later, and accept a cap on the good years in exchange for a floor on the bad ones
• Own a business and need permanent coverage for key person or buy-sell planning

It usually does not suit you if you:

• Only need coverage while children are young or the mortgage is unpaid; term is usually far cheaper
• Have not yet built an emergency fund
• Need the money back within the first two years. A portion of the cash value can be taken as a withdrawal or a loan beginning in policy year 3, so you don’t have to wait 10 years

A 401(k) or a Roth IRA is a separate bucket of money, and many people use both. Retirement accounts are built to grow savings at low cost, and we encourage everyone to take any employer match on offer. IUL is life insurance first: it pays a death benefit, and its cash value can supplement retirement income later. Whether it belongs alongside your 401(k) depends on whether you need permanent coverage and can fund it.

Questions to ask before you sign

• What are the cap (if any), participation rate, spread and floor, and how has this insurer changed them on its existing policies?
• What does every charge cost, year by year?
• What does the guaranteed column show, and when would the policy lapse at a lower crediting rate?
• What happens if I pay less than planned, or skip a year?
• How long do surrender charges last?
• How are policy loans charged, and is the policy designed to avoid becoming a MEC?

See the trade-off for yourself

The free IUL Cap & Floor Explorer replays real S&P 500 years with the cap (or none), participation rate, spread, floor and yearly charge you choose. It shows which years the cap cut short, which years the floor protected, and what charges take. Our indexed universal life guide compares IUL with term and whole life in more detail.

If you are weighing an IUL, or already own one and are not sure how it is doing, a free strategy session starts with whether you need permanent coverage at all.
