At a glance

Coverage type

Permanent life insurance — does not expire if the policy stays funded

Death benefit

Contractually guaranteed as long as the policy remains in force

Cash value floor

Often 0% — meaning credited interest cannot go negative in a down index year

Illustrated growth

Not guaranteed — only the guaranteed column in an illustration must be honored

What IUL Insurance Actually Is

Indexed universal life insurance is a form of permanent life insurance with a flexible premium. Unlike term insurance, it does not expire after a set period, which is why estate planners sometimes consider it. The policy builds cash value over time, and that cash value earns interest credited according to a formula tied to the performance of a market index such as the S&P 500.

Critically, your money is never placed directly into the stock market. The insurer uses the index only as a reference point for calculating how much interest to credit. A floor — often set at zero percent — means a bad index year does not reduce your cash value through negative crediting. A cap or participation rate, set by the insurer and subject to change, limits how much of any index gain you actually receive.

Why Permanent Coverage Matters for Estate Planning

Term life insurance ends. If your estate planning goal requires a death benefit to be available decades from now — to equalize an inheritance among heirs, fund a trust, or cover estate settlement costs — a policy that might lapse before you die defeats the purpose. Permanent insurance, when properly funded, is designed to stay in force for your lifetime.

The death benefit paid to named beneficiaries generally passes outside of probate, which can simplify the transfer of assets to heirs. Working with an estate attorney alongside a licensed insurance professional helps ensure the policy ownership and beneficiary structure align with your overall plan. AskLily can connect you with a licensed independent insurance professional; estate tax and legal strategy questions belong with a qualified attorney.

• Death benefit passes directly to named beneficiaries, bypassing probate
• Permanent coverage can remain in force regardless of future health changes
• Policy ownership structure matters — an attorney should review it
• IUL is one tool; it rarely stands alone in a complete estate plan

The Costs and Risks You Must Understand

Every month, the insurer deducts the cost of insurance, administrative charges, and any rider fees directly from your cash value — whether or not any interest was credited that month. In years when the index performs poorly and the floor prevents negative crediting, those charges still come out. If cash value erodes far enough, the policy can lapse unless you pay additional premium.

FINRA has noted that IUL policies are complex products and that consumers should review illustrations carefully before purchasing. The guaranteed column in an illustration assumes the minimum credited rate and the maximum charges the insurer is allowed to apply. That column is the only performance scenario the contract must deliver. Non-guaranteed columns showing higher growth are projections, not promises.

Ask any licensed professional you work with to run the illustration at multiple assumed rates — including zero percent — and show you how long the policy stays in force under each scenario. Understanding the downside is just as important as understanding the potential upside.

• Monthly charges reduce cash value regardless of index performance
• Caps and participation rates can be changed by the insurer over time
• Underfunding is a leading reason IUL policies lapse prematurely
• Non-guaranteed illustrated values are projections only
• A policy lapse can have tax consequences — discuss with a tax advisor

Who IUL for Estate Planning May Be Worth Exploring

IUL is generally worth a serious conversation for adults who need permanent life insurance coverage, have already funded available retirement accounts, and are looking for additional ways to build long-term cash value with some protection against negative index years. It tends to fit people with a longer time horizon who can commit to consistent funding.

It is typically not the right starting point for someone whose primary need is affordable income replacement over a defined period, or who has not yet addressed foundational financial priorities. The NAIC's consumer guides recommend comparing several policy types and asking a licensed professional to explain the differences before deciding.

• Already maxing out retirement account contributions
• Need permanent — not temporary — coverage for estate goals
• Comfortable with policy complexity and ongoing monitoring
• Working with both a financial professional and an estate attorney

How to Read an IUL Illustration Before You Sign

Every IUL illustration contains a guaranteed column and one or more non-guaranteed columns. Focus first on the guaranteed column: it shows what happens if the insurer credits the minimum rate and applies maximum charges for the entire life of the policy. If the policy lapses in the guaranteed column before your expected lifetime, that is a meaningful risk signal.

Then compare the assumed rate in the non-guaranteed column to the current cap on the policy. If the illustration assumes six percent annual crediting but the cap is nine percent, that scenario requires the index to perform strongly most years. Ask the licensed professional to show you results at four percent and at zero percent as well, so you can see the range of realistic outcomes before committing.

What to do next

1. Step 1: Clarify Your Estate Planning GoalWrite down what you need the death benefit to accomplish — equalizing an inheritance, funding a trust, covering final expenses, or something else. A clear goal helps a licensed professional determine whether IUL, another permanent product, or a combination is the right fit.
2. Step 2: Coordinate With Your AttorneyPolicy ownership and beneficiary designations have legal and potential tax consequences. Before applying for any permanent life insurance for estate purposes, share the plan with a qualified estate attorney. AskLily connects you with licensed insurance professionals; legal and tax advice come from separate advisors.
3. Step 3: Review the Full IllustrationRequest the guaranteed column and at least two non-guaranteed scenarios at different assumed credited rates. Ask how long the policy stays in force under each. The NAIC recommends consumers review illustrations carefully and understand what is and is not guaranteed before signing any application.
