What Is Index Universal Life (IUL) Insurance?
Index Universal Life (IUL) insurance is a type of permanent life insurance designed to provide lifelong coverage with a cash value component. It combines death benefit protection with interest crediting tied to the performance of a market index, such as the S&P 500®, without direct market participation.
IUL policies are issued by insurance carriers and are structured to offer downside protection while allowing for potential interest accumulation based on index performance, subject to policy terms.

How Index Universal Life Insurance Works
Premiums paid into an IUL policy are allocated to cover insurance costs, policy expenses, and a cash value account. The cash value is credited interest based on a chosen index, but it is not invested directly in the market.
Interest crediting is governed by contract-defined features such as caps, participation rates, or spreads. These limits determine how much interest may be credited during a given period.
Individuals researching permanent life insurance options often seek a broader understanding of how these policies are structured and used in long-term planning.

Key Features to Understand

In addition to IUL policies, some individuals explore other insurance-based approaches when evaluating protection-focused strategies. One commonly reviewed option includes fixed indexed annuities, which are structured differently and serve distinct planning purposes depending on individual objectives.
Important Considerations
IUL insurance is not designed for short-term use. Policies may include surrender charges during the early years, and withdrawals or loans may reduce policy values and death benefits. Suitability depends on individual goals, time horizon, and financial circumstances. Policy provisions, fees, and limitations should be reviewed carefully.
