What is a fixed indexed annuity?
A fixed indexed annuity (FIA) is a contract with an insurance company that offers the growth potential of a market index — like the S&P 500 — while guaranteeing that your principal is 100% protected from market losses.
You are not investing directly in the stock market. Your money stays with the insurer. The index is simply used as a benchmark to calculate how much interest gets credited to your account.
The core trade-off
Think of an FIA as a way to participate in some of the market's upside without risking any of your principal on the downside.
You trade unlimited growth potential for the guarantee that you'll never lose money to a market crash.
How a fixed indexed annuity works
You fund the annuity
You make a lump-sum premium payment (minimums typically $10,000–$25,000), then choose how to allocate among available index-linked crediting strategies and/or a fixed interest account.
The index tracks performance
During each crediting period (typically 1 year), the insurer tracks your chosen index. If the index gained, interest is credited and locked in permanently. If it lost value, you receive 0% — your account value is unchanged.
Interest is locked in (annual reset)
Most FIAs use an annual reset: at the end of each period, your gains are locked in and become your new starting point. Even if the market drops the following year, your previous gains are protected.
You access your money
At the end of the surrender period (typically 5–10 years), you can withdraw, roll into a new annuity, or annuitize into a guaranteed income stream. Most contracts allow penalty-free withdrawals of up to 10% per year.
How your returns are calculated
The insurer uses crediting methods to determine how much of the index's return is credited to your account. Understanding these is essential to evaluating any FIA.
Cap Rate
A cap sets the maximum interest your annuity can earn in a single crediting period.
Example
Your FIA has an 8% cap. The S&P 500 gains 12% → you receive 8%. If the index gained 5%, you'd receive the full 5%. Caps typically range from 5%–12%.
Participation Rate
A participation rate is the percentage of the index's gain that gets credited to your annuity.
Example
Your FIA has a 70% participation rate. The S&P 500 gains 10% → you receive 7%. Rates can exceed 100% on some products, especially proprietary indexes.
Spread (Margin / Asset Fee)
A spread is a fixed percentage subtracted from the index gain before interest is credited.
Example
The S&P 500 gains 9%. Your FIA has a 3% spread → you receive 6%. If the index gains less than the spread, you receive 0% — not a loss.
Combination Strategies
Some FIA contracts apply multiple limits simultaneously (e.g., an 80% participation rate with a 9% cap).
Example
80% participation with a 9% cap: index returns 10% → 80% × 10% = 8%. Index returns 12% → 80% × 12% = 9.6%, but capped at 9%.

Key benefits of fixed indexed annuities
Protection With Growth Potential
Your money is never at risk from market declines, yet can earn meaningful returns when markets rise.
Annual Reset Locks in Gains
Once credited, interest is yours permanently. Future market declines can't take back prior years' gains.
Tax-Deferred Compounding
Interest grows without annual taxation — a significant advantage over taxable accounts over long horizons.
Optional Lifetime Income
Income riders can guarantee lifetime income regardless of what happens to your account value.
No Annual Fees on Base
The base FIA carries no annual fees. Fees only apply if you elect optional riders.
Diverse Index Strategies
Choose from multiple indexes and crediting methods to diversify growth potential within one contract.
