Tying cash value to a market index

Published May 30, 2026

Indexed universal life (IUL) is a form of universal life insurance whose cash-value growth is linked to a market index rather than a fixed rate. Caps and floors limit both the gains and the losses, which makes it more complex than other permanent policies.

How the indexing works

Your cash value earns interest based on the performance of an index, but with a cap that limits the upside and a floor that limits the downside, often at zero. You are not directly invested in the market.

The trade-offs

IUL can offer more growth potential than a fixed universal life policy, but caps, participation rates, and fees can reduce returns. Like other universal life, it can lapse if the cash value is not maintained.

Who it may suit

IUL is generally for people who want permanent coverage with some growth potential and are comfortable with complexity. It is usually not the first choice for someone who simply needs affordable coverage.

Frequently asked questions

Is my money invested in the stock market with an IUL?

No. The cash value earns interest based on an index's performance, but you are not directly invested. Caps and floors limit how much the value can rise or fall.

What are caps and floors?

A cap limits how much interest your cash value can earn in a period, and a floor limits how much it can lose, often at zero. Together they shape the policy's growth.

Is IUL right for most people?

Not necessarily. It is complex and carries fees and limits. People who simply need affordable protection often choose term life instead.
