1. What Is a Fixed Index Annuity?

A Fixed Index Annuity (FIA) is a retirement product that:

  • Protects your money from market losses
  • Earns interest based on an index (like the S&P 500)
  • Grows tax‑deferred
  • Can provide lifetime income

FIAs are not stock market investments. You do not own shares. Instead, the index is used as a measuring tool to calculate interest.

2. How Fixed Index Annuities Work

Zero Market Losses

If the index goes down, your return is never below 0%. Your principal is protected.

Market-Linked Growth

If the index goes up, you earn interest based on the index performance — up to certain limits.

Tax‑Deferred Growth

You don’t pay taxes until you withdraw money, allowing faster compounding.

Income Options

FIAs can be turned into guaranteed lifetime income, similar to a pension.

3. How Index Crediting Works

FIAs use several methods to calculate interest. The most common are:

1. Cap

A maximum interest rate you can earn for the year.

2. Participation Rate

You earn a percentage of the index gain.

3. Spread

A fee subtracted from the index gain.

4. Performance Trigger

If the index is positive at all, you earn a preset rate.

5. Multi‑Year Strategies

Some FIAs use 2‑year or 3‑year crediting periods for potentially higher returns.
