How an FIA Earns Interest
Savings Account
Earns a fixed rate set by the bank. FDIC insured. Predictable but typically low returns.
Typical rate
~2%
Stock Portfolio
Direct gains and losses. Full market participation with no floor protection.
Range
-38% to +30%
Fixed Indexed Annuity
Index-linked credits with a 0% floor. Gains locked in annually. Never lose to market drops.
Typical range
0% to 9%+
Here's the fundamental concept: your money is not in the stock market. The insurance company holds your premium in their general account. They use a market index — like the S&P 500 — purely as a measuring stick to determine how much interest to credit to your account each year.
Because your money never touches the market, you can't lose it to market declines. The trade-off is that you don't capture 100% of the upside — your gains are shaped by the crediting method you choose.
The Annual Crediting Cycle
Every year on your contract anniversary, the insurance company measures the index and credits interest to your account. Here's how the cycle works:
How Interest Gets Credited Each Year
Anniversary Date
Starting index value is recorded as your baseline.
Crediting Period
1 year
The market moves throughout the year. Your account value is unaffected.
Measurement
Ending index value is compared to the start to determine the gain or loss.
Interest Credited
Gains are locked in (subject to cap/participation). 0% if the index was negative. New baseline is set.
Anniversary Date
Starting index value is recorded as your baseline.
Crediting Period

The market moves throughout the year. Your account value is unaffected.
Measurement

Interest Credited
Gains are locked in (subject to cap/participation). 0% if the index was negative. New baseline is set.
Once credited, those gains are permanent
Even a 40% market crash next year can't take away your previously credited interest. Each year's gains are locked in and become part of your new baseline. This is the annual reset feature that makes FIAs unique.
Crediting Methods Explained
Each crediting method shapes your returns differently. Here's how the most common strategies work, with typical rate ranges.
Fixed Account
2.5% – 3.5%Earns a declared rate each year, regardless of what the market does. Think of it like a CD inside your annuity — predictable and safe.
Annual Cap Rate
5% – 9.25%You earn the full index gain, up to a maximum cap. If the S&P 500 gains 15% and your cap is 9%, you receive 9%. If it gains 6%, you get the full 6%. Think of a bucket that fills to a maximum height — it captures all the rain up to the brim.
Uses annual point-to-point measurement. 0% floor in down years.
Participation Rate
25% – 160%+You earn a percentage of the index gain — like taking a slice of the pie. A 55% participation rate on a 20% S&P 500 gain gives you 11%. Rates vary dramatically by index: 25%–55% on the S&P 500, but 100%–160%+ on volatility-controlled indices.
Typically uncapped. 0% floor in down years.
Monthly Point-to-Point
1.95% – 2.30% monthly capEach month's index gain is capped, then all twelve months are summed. Positive months are capped, but negative months are uncapped — so a few bad months can offset many good ones. Works best in steadily rising markets with low volatility.
Uses monthly sum measurement. Annual result floored at 0%.
Two-Year Point-to-Point
50% – 215% participationMeasures the index over a 2-year period instead of annually. The longer measurement window often comes with higher participation rates. The trade-off is less frequent lock-in — your gains are only credited every two years.
Daily Average with Spread
2% – 5% spreadCalculates the daily average of the index over the year, then subtracts a fixed spread. The averaging smooths out short-term volatility, and the spread is the insurance company's cost. If the average gain is 8% and the spread is 3%, you earn 5%.
0% floor — you never owe the spread if the index is flat or down.
Inverse Performance Trigger
6% – 9.5%The contrarian strategy. Earns a declared rate in down years and 0% in up years. Sounds counterintuitive, but it provides consistent crediting during bear markets — exactly when other strategies earn nothing. Often paired with traditional strategies for diversification.

Understanding Index Options
The index you choose matters as much as the crediting method. Different indices carry different hedging costs for the insurance company, which directly affects the rates they can offer you.
S&P 500
Most recognized broad market index
The benchmark most people know. Higher potential volatility means higher hedging costs for the carrier, which translates to lower caps and participation rates (e.g., 5%–9.25% cap, 25%–55% participation).
Volatility-Controlled Indices
5% – 12% target volatility
Designed with built-in dampening mechanisms that reduce wild swings. Because they're cheaper to hedge, carriers offer significantly higher participation rates — often 100%–160% or more. The smoother ride comes with a shorter track record than the S&P 500.
Multi-Asset / Hybrid Indices
Equities + bonds + alternatives
Blend multiple asset classes for smoother performance. Diversification across equities, bonds, and sometimes commodities or real estate. Like volatility-controlled indices, they typically come with higher participation rates due to lower hedging costs.
Why higher participation doesn't always mean better returns
Higher participation rates on volatility-controlled indices reflect lower hedging costs for the carrier — not necessarily better outcomes. A 55% participation rate on the S&P 500 and a 140% rate on a vol-controlled index may produce similar long-term results. The right choice depends on your outlook and risk preference.

Notice 2018 and 2022: When the S&P 500 dropped -6.2% and -19.4% respectively, both FIA strategies credited 0%. Your account value held steady while unprotected portfolios suffered significant losses.
