Indexed Annuity
An indexed annuity (also called a fixed indexed annuity, or FIA) credits interest based on the movement of a stated market index — most commonly the S&P 500, but increasingly proprietary "uncapped" indices designed for the annuity market. The consumer does not own shares of the index. The carrier uses the index level to calculate a credit at the end of each crediting period using a contractually defined formula (cap, participation rate, spread). The floor is typically zero, meaning a negative index period results in zero credited interest rather than a loss. Indexed annuities are not registered as securities; they are state-regulated insurance products. The principal is protected from market decline (the floor is zero) but the credited interest is capped or scaled to limit upside.
A 62-year-old places $150,000 in an FIA with a 7% annual point-to-point cap on the S&P 500 and a 0% floor. In year one, the S&P 500 returns 18%. The contract credits 7% (the cap) — $10,500. In year two, the index declines 12%. The contract credits 0% (the floor). In year three, the index returns 4.5%. The contract credits 4.5% (below the cap, no scaling). The contract value at the end of year three is $167,837.
Why it matters
Indexed annuities are designed for consumers who want principal protection combined with some upside participation in equity markets. The structure works well when the index has long flat or volatile periods (the floor protects principal) and works less well when the index has long sustained bull markets (the cap or participation rate limits gains). Over long horizons, indexed annuities historically underperform direct index investments but outperform pure fixed annuities — placing them between bonds and equities in expected return and risk profile.
How to evaluate
The crediting parameters (cap, participation rate, spread) drive returns. Equally important: how often the carrier can change them. Annual reset of caps gives the carrier the ability to lower the cap after the consumer has locked in the surrender period. Read the minimum guaranteed cap or participation rate in the contract — that is the floor under future renewals.
In the contract
Look for the "interest crediting" section, which lists each available crediting method (annual point-to-point, monthly sum, monthly average) and the current cap/participation/spread. The "rate renewal" or "minimum guaranteed rates" section specifies the contractual floors.
