Quick answer

An indexed universal life illustration shows how a policy might look under stated assumptions. The guaranteed column is the conservative contractual path. Non-guaranteed columns use assumed caps, participation rates, and charges that can change. Read both, and do not treat a mid-range or current-assumption number as a promise.

If you have been shown an indexed universal life (IUL) policy, you have probably been shown an illustration: a multi-page projection of premiums, account value, and death benefit over many years. Illustrations are useful when you know what they are, and misleading when you treat a middle column as a forecast. The National Association of Insurance Commissioners (NAIC) has long warned consumers that illustrations are not guarantees, and that the policy contract — not the sales projection — controls what is actually guaranteed.

This article is a reading guide, not a prediction of returns and not a recommendation of IUL over term or whole life. For how IUL works in general, see IUL pros and cons, indexed universal life, and term versus whole life versus IUL. Premiums, caps, participation rates, and charges vary by product and can change on the terms in the contract.

Start with the guaranteed column

A complete illustration typically includes a guaranteed, or minimum, column. That path uses the contractual guarantees: often a 0% index floor in years the index credit is zero, guaranteed maximum charges, and the minimum interest or crediting treatment the contract requires. On that path, a policy can look much thinner than the “current” or “assumed” path sitting next to it. In some cases the guaranteed column shows the policy running out of money if planned premiums and charges do not keep it in force.

Read that column first, even if it is not the one that was highlighted. Ask, plainly: if only the guarantees came true, would this policy still be in force at the ages I care about, with the death benefit I think I am buying, at the premium I plan to pay? If the answer is no, you need a plan for paying more, reducing the death benefit, or choosing a different product. That is not a minor detail. It is the conservative picture the illustration is required to show.

Non-guaranteed columns are assumptions

Other columns use non-guaranteed assumptions: a credited rate based on a stated cap, participation rate, and spread; current (not maximum) policy charges; and sometimes a midpoint or an alternative scenario. Those numbers can look smooth and attractive over 20 or 30 years. They are not a history of the policy you are buying, and they are not a promise. Caps, participation rates, and charges can be changed by the insurer within the contract’s limits. An index can have years at the floor. A year of zero credit is not a rare theoretical event; the floor is there because it can happen.

When you compare two illustrations, look at whether they use the same assumed rate, the same premium pattern, and the same charges. A more aggressive assumed crediting rate can make one product look “better” without telling you anything reliable about which contract you should own. Ask for a comparable assumption, and ask to see a lower-than-current scenario as well as the illustrated current one.

Look at the charges and the planned premium, not only the ending value

IUL has cost of insurance charges, expense charges, and sometimes premium loads and rider charges. These come out of the policy account. In early years, and in later years if the insured’s cost of insurance has risen, charges can outweigh credited interest. That is how a policy with a 0% floor can still lose value or lapse. An illustration that holds a level premium while charges rise is only sustainable if the account value and the crediting assumptions keep up.

Ask which premium on the illustration is required to keep the policy in force on the guaranteed path, and which premium is only enough if the non-guaranteed assumptions hold. Those two numbers are often different. Paying the lower “planned” premium can be a problem if crediting or charges are worse than illustrated. If you see loans or withdrawals in the illustration, usually later in the policy, remember that those are also non-guaranteed in result: a loan reduces the death benefit, and poor performance can make a distribution plan unsustainable. This article will not walk through income-style illustrations as if they were a retirement paycheck. If that is how a policy was presented, slow down and have a licensed insurance broker and, if needed, a tax professional review it.

Questions to take to the meeting

  • Show me the guaranteed column at the ages I care about. Does the policy stay in force at my planned premium?
  • What cap, participation rate, and charges are assumed in the non-guaranteed column, and which of those can change?
  • Can I see the same illustration at a lower assumed crediting rate?
  • What happens if I miss a planned premium, or if I need to reduce the death benefit?
  • Which features are riders, and what do they cost?

Then compare IUL with the alternatives that might actually fit: term for a temporary need, whole life if you want more guarantees, or no permanent policy if the need is smaller than the complexity. A licensed insurance broker should be willing to put those options next to the illustration rather than asking you to judge IUL in isolation.

The bottom line

Read an IUL illustration as a set of scenarios, not as a forecast. Start with the guaranteed column, treat non-guaranteed values as assumptions that can change, and match the planned premium to a path you would still accept if crediting is lower or charges are higher than the middle column shows. The contract is the document that matters. A licensed insurance broker can sit with the illustration and the policy form and explain both before you apply.

Frequently asked questions

Is an IUL illustration a guarantee?

No. Illustrations are projections under stated assumptions. Only the guarantees in the policy contract — such as a floor and maximum charges — are guaranteed, and even then only as the contract describes them.

What is the guaranteed column on an IUL illustration?

It is the path that uses the contract's guarantees, including maximum charges and minimum crediting treatment. It is often less favorable than the current-assumption column and is the conservative picture you should read first.

Why can an IUL policy lose value if there is a 0% floor?

The floor typically limits index interest crediting, not policy charges. Cost of insurance and other expenses can still reduce the account value in a year the index credit is zero, and the policy can lapse if premiums and value do not keep it in force.

Should I compare IUL illustrations using the highest assumed rate?

No. Ask for comparable assumptions, and look at a lower-than-current scenario as well. A higher assumed crediting rate can make a policy look stronger without changing the contract.

Is IUL better than whole life because the illustration looks larger?

Not for that reason. Whole life and IUL are different contracts with different guarantees and risks. Compare the guarantees, the charges, and the need, not a single illustrated ending value.
