Indexed universal life insurance (IUL) is a permanent life insurance policy that combines lifelong coverage with cash value growth linked to a market index, such as the S&P 500. IUL policies offer flexible premiums and tax-advantaged cash value accumulation, making them attractive for long-term protection, retirement planning, and estate planning strategies.
Indexed Universal Life Insurance: Complete Guide to Coverage, Costs & Providers
Indexed universal life insurance (IUL) is a form of permanent life insurance that provides lifelong coverage while allowing policyholders to build cash value tied to the performance of a market index. Because of its flexibility and growth potential, IUL has become a popular option among individuals seeking both insurance protection and long-term financial planning opportunities.
Unlike term life insurance, IUL policies can remain in force for life if adequately funded. Unlike traditional universal life insurance, cash value growth is linked to an external market index rather than a fixed interest rate.

Indexed universal life insurance is a permanent life insurance policy that includes:
