What Is a Fixed Index Annuity? Plain-English Guide

The Basics

A fixed index annuity (FIA) is a contract with an insurance company that protects your principal while letting you earn interest based on a market index like the S&P 500.

When the index goes up, you earn a portion of the gain (subject to a cap or participation rate). When the index goes down, you earn zero — but you never lose money. Your principal is always protected.

How the Interest Is Calculated

FIAs use crediting methods like annual point-to-point, monthly averaging, or monthly cap. The most common is annual point-to-point: they compare the index value at the start and end of each year. If it went up, you earn a portion of that gain.

Most FIAs have a 'cap' (e.g., 8-12%) that limits how much you can earn in a good year, and a 'floor' (typically 0%) that protects you in bad years. Some use a 'participation rate' instead of a cap — for example, you might earn 50% of the index gain with no cap.

Who Should Consider an FIA?

FIAs are best for people who want more growth potential than a traditional fixed annuity or CD, but can't afford to lose money. They're especially popular with pre-retirees (ages 55-70) who have 5-10+ years before they need income.

If you want guaranteed lifetime income, many FIAs offer optional income riders that create a guaranteed paycheck for life — regardless of how the market performs.
