Fixed Indexed Annuities Explained: How They Work

A fixed indexed annuity (FIA) is an insurance contract that earns interest based on the performance of a market index, such as the S&P 500, while protecting your principal from market losses. Unlike direct stock market investments, you do not actually invest in the index. Instead, the insurance company uses the index as a benchmark to calculate the interest credited to your account.

The key feature that distinguishes FIAs from other financial products is the 0% floor. This means that even if the linked index declines in value, your account will not lose money due to market performance. In years when the index performs well, you earn interest up to certain limits. In years when the index declines, you simply earn 0% for that period, and your previous gains are locked in.

FIAs are regulated as insurance products, not securities. They are not insured by the FDIC or any federal agency. All guarantees are backed by the financial strength and claims-paying ability of the issuing insurance company.

Understanding how interest is calculated is essential to evaluating any FIA. Insurance companies use several crediting methods to determine how much index-linked interest you earn.

Point-to-Point: This is the most common method. It compares the index value at the start of a crediting period (usually one year) to the value at the end. If the index gained 10% and your cap is 7%, you earn 7%. If the index lost 5%, you earn 0% (the floor).

Monthly Sum (or Monthly Average): This method tracks the index change each month and adds them together. Monthly caps apply to each month individually. This method can produce different results than point-to-point because large single-month gains may be capped.

The crediting method you choose can significantly affect your returns. Your advisor can help you understand which method aligns best with your goals and market outlook.

FIAs use several mechanisms to limit the maximum interest credited to your account. Understanding these terms is critical before purchasing any FIA product.

Cap Rate: The maximum interest you can earn in a crediting period. For example, if the cap is 7% and the index gains 12%, you earn 7%. Caps are set by the insurance company and can be adjusted at renewal, though they cannot go below a guaranteed minimum stated in the contract.

Participation Rate: The percentage of the index gain that is credited to your account. If the participation rate is 80% and the index gains 10%, you earn 8%. Some FIAs offer participation rates above 100% on certain index strategies.

Spread (or Margin): A percentage subtracted from the index gain before interest is credited. If the spread is 2% and the index gains 10%, you earn 8%. Spreads are sometimes used instead of or in combination with caps.

It is important to note that these rates are illustrative examples only and do not represent any specific product. Actual rates vary by carrier, product, and market conditions. Your advisor can help you compare current offerings from multiple insurance companies.

Consider Margaret, 63, a retired school principal with $300,000 in savings. She wants growth potential but cannot afford to lose principal this close to retirement. She works with her advisor to purchase a hypothetical FIA with a 7% cap, point-to-point crediting, and a 0% floor.

In Year 1, the S&P 500 gains 15%. Margaret earns 7% (the cap), and her account grows to $321,000. In Year 2, the market drops 20%. Margaret earns 0% (the floor), and her account stays at $321,000, with her previous gains locked in. In Year 3, the market recovers 12%. Margaret earns 7% again, bringing her account to $343,470.

This example is purely hypothetical and does not represent any specific product or guarantee of future results. Actual results will vary based on the product, crediting method, and market conditions. However, it illustrates the core concept: participation in market gains with protection from market losses.

Get Matched with an Advisor

Many FIAs offer optional riders that add features to the base contract, typically for an additional annual fee (often 0.5% to 1.5% of the account value).

Guaranteed Lifetime Withdrawal Benefit (GLWB): This rider guarantees you can withdraw a certain percentage of a benefit base each year for life, regardless of your actual account value. The benefit base may grow at a guaranteed rate during the deferral period, which is separate from your actual account value.

Death Benefit Rider: This rider can provide your beneficiaries with a guaranteed minimum death benefit, which may be more than the account value at the time of death. For more on how beneficiary designations work with annuities, see our guide on annuity beneficiary rules.

Riders add cost and complexity to an FIA. Not everyone needs them. Your advisor can help you determine whether the additional cost of a rider is justified based on your specific retirement income needs. For a comparison of FIAs with MYGAs, read our article on MYGA vs FIA.

FIAs are designed for people who want growth potential with downside protection. They tend to work best for retirees or near-retirees who have a moderate risk tolerance and a time horizon of at least 5 to 10 years.

An FIA may be a good fit if you want to participate in market gains without risking your principal, you are looking for tax-deferred growth, you want the option to convert your savings into guaranteed lifetime income, or you have already maximized other tax-advantaged accounts.

An FIA may not be the best choice if you need full liquidity for your savings in the near term, you are comfortable with market risk and want maximum growth potential (in which case direct market investments may be more appropriate), or you have a very short time horizon.

The best way to determine if an FIA fits your retirement plan is to speak with a qualified advisor who can evaluate your complete financial picture. Learn how to choose the right annuity advisor for your needs.
