Cap Rate
A cap rate is the maximum interest that can be credited to an indexed annuity in a given crediting period, regardless of how high the underlying index moves. Caps are most commonly applied to annual point-to-point crediting methods on broad-market indices like the S&P 500. The cap is set at the contract's issue date but is typically reset annually by the carrier within a contractual range, with a minimum guaranteed cap (often 1% to 2%) below which the carrier cannot drop the cap during the contract's surrender period.
A 7% annual cap is applied to an S&P 500 indexed annuity. In year one, the S&P 500 returns 14%. The contract credits 7% (capped). In year two, the index returns 5%. The contract credits 5% (below cap, full credit). In year three, the index returns -8%. The contract credits 0% (floor). Over the three years, the consumer received 12% total — versus a direct index investment that would have produced approximately 10.6% over the same period (including the negative year). The cap protected the down year but limited the up years.
Why it matters
The cap rate is the single most important number in a fixed indexed annuity. It determines how much of the index upside the consumer actually captures. Two contracts with identical surrender schedules and identical carrier ratings can have wildly different long-term returns depending on the cap. A 5% cap in a 10% market environment produces meaningfully different outcomes than an 8% cap in the same environment.
How to evaluate
Compare current caps across carriers (most quote 3% to 9% for annual point-to-point S&P 500 caps). Read the minimum guaranteed cap — the contractual floor under future cap declarations. A 7% current cap on a contract with a 1% minimum guaranteed cap is materially different from a 7% current cap with a 4% minimum guaranteed cap.
In the contract
Look for "interest crediting parameters," "annual cap," "minimum guaranteed annual cap," and "renewal rate." The renewal-rate provision specifies when and how the carrier can change the cap.
