A fixed indexed annuity (FIA) credits interest based on the performance of a market index, with a floor that protects your principal from market losses. It aims for more growth potential than a fixed annuity while still protecting principal.

This cornerstone guide explains the mechanics — caps, participation rates, and crediting methods — in plain English.
