What an IUL illustration is really showing you

An indexed universal life illustration is a long document full of columns, and it is the single most misread piece of paper in this business. It is not a projection of what will happen. It is a picture of what the policy would do if a specific set of assumptions held true for decades. Once you understand which parts are contractual and which are assumed, the document becomes genuinely useful.

First, what an IUL actually is

Indexed universal life is permanent life insurance with a flexible premium and a cash value whose interest is linked to the movement of a market index. You do not own the index, you are not invested in the market, and you do not receive dividends from it. The insurer credits interest according to a formula in the contract, which typically includes a cap or a participation rate that limits the upside and a floor that limits the downside. Policy charges, including the cost of insurance, come out of the cash value regardless of how the index performed.

The columns that matter

Most illustrations show at least two scenarios side by side. One is the guaranteed scenario: the worst the contract allows, using the minimum crediting rate and the maximum charges the insurer is permitted to apply. The other is a non-guaranteed scenario built on a chosen crediting rate and today’s current charges. Some illustrations add a mid-point. The guaranteed page is the only one that describes what the company is contractually obliged to do.

1. Find the guaranteed columns first. Read the year the policy would lapse under those assumptions.
2. Find the assumed crediting rate on the non-guaranteed pages, and note that it is a single flat rate applied every year — real index returns are not flat.
3. Look at the annual policy charges column. It is usually there, and it usually rises with age.
4. Check the premium the illustration assumes you pay, and for how many years. Illustrations often assume perfect, uninterrupted funding.
5. Look at the age at which coverage is shown ending. Many illustrations stop at a chosen age rather than at life expectancy.

Why a small change in assumption moves everything

The cash value in an IUL is what is left after charges each year, compounded. Because charges are deducted from the value and the value is what earns interest, a lower crediting rate does not reduce the outcome proportionally — it compounds against you. That is why the same policy can look excellent at one assumed rate and fail decades later at a rate only slightly lower. Ask for the illustration to be re-run at a materially lower rate. If it only works at the optimistic one, you have learned something important.

What the document cannot tell you

An illustration cannot tell you what the index will do, what the insurer will set caps at in twenty years, or whether you will keep funding the policy through a job change or an illness. Those three unknowns determine most of the outcome. An IUL that is funded consistently at an adequate level and reviewed regularly is a very different thing from the same contract funded at the minimum and never looked at again.

This product is life insurance, not an investment or a bank account, and it is not right for everyone. Tax treatment depends on how the policy is structured, whether it stays in force and your own circumstances, so speak with your own tax adviser. If you already own a policy, do not cancel or reduce it based on an illustration for a new one — ask for both to be reviewed side by side first.
