Indexed Universal Life is a form of permanent life insurance. If you remember only one thing, remember this: it is a life insurance contract, not a share of the stock market.

Premiums typically split into two jobs. One job is to pay for the insurance protection and the company’s expenses. The other job, if the policy is funded that way, is to build cash value.

The cash-value portion may be credited with interest linked to a market index. You do not own the index. The insurer uses a formula that can include a cap (a maximum credit), a participation rate (how much of the index change is used), and a floor (often 0% for that segment).

A floor can help explain why some people look at IUL when they worry about market drops. It does not mean the policy cannot lose value. Charges continue. Poor funding, loans, or a long period of low credited interest can put a policy under stress.

Suitability matters. Health, budget, time horizon, and the need for life insurance all belong in the conversation. If someone presents an IUL as a guaranteed retirement paycheck, ask for the illustration, the assumptions, and the list of charges.
