An indexed universal life (IUL) policy credits interest to its cash value based on:

Explanation

An indexed universal life policy ties its interest crediting to the movement of a market index (such as the S&P 500), but it applies a cap that limits the upside and a floor (often zero percent) that protects against index losses, so the cash value can grow with the market while being shielded from negative returns. It is not a single fixed rate, not the dividend scale of a participating policy, and not simply the prime rate. The index-linked crediting with a cap and floor is the essence of IUL.
