Annuities can be a valuable tool for ensuring a steady income stream and managing financial risk, particularly during retirement. One important aspect of certain annuities is the trigger rate. The trigger rate plays a significant role in determining the growth and performance of the investment. Knowing how the trigger rate is calculated, along with its benefits and drawbacks, can help inform your strategy.
A financial advisor can review different types of annuities to help you choose the best fit for your retirement budget.
What Is the Trigger Rate of an Annuity?
A trigger rate is a predetermined percentage that an annuity’s benchmark index must reach for the annuity to credit interest to the account. If the index performance meets or exceeds the trigger rate, the annuity will credit a specified rate of interest to the account value. However, if the index performance falls below the trigger rate, no interest will be credited for that period.
Trigger rates are most commonly associated with indexed annuities. (Credit interest is based on the performance of a specified market index, such as the S&P 500.) Some variable annuities may also employ trigger rates in their guaranteed living benefit riders. This can provide a minimum level of income regardless of market performance.
At the beginning of each crediting period (typically annually), the annuity issuer will compare the performance of the specified index to the trigger rate. If the index performance equals or surpasses the trigger rate, the annuity will credit a predetermined rate of interest to the account. This credited interest is then locked in and cannot be lost due to future market downturns. If the index performance is below the trigger rate, no interest will be credited for that period. (The account value will not decline.)
In short, a trigger rate annuity works by offering a guaranteed minimum return, typically ranging from 1% to 4%, while also providing the potential for higher returns if the market performs well.
How the Trigger Rate Is Calculated
The trigger rate for an indexed annuity is determined by a combination of factors, including the participation rate, cap rate and spread. Let’s break down the formula to see how each component contributes to the final trigger rate:
- Participation rate: This represents the percentage of the index’s performance that will be credited to the annuity. For example, if the participation rate is 80% and the index gains 10%, the annuity would be credited with 8% (80% of 10%).
- Cap rate: The cap rate sets the maximum rate of return that can be earned. If the index’s performance exceeds the cap rate, the annuity’s return will be limited to the cap rate.
- Spread: The spread is a percentage that is subtracted from the index’s performance before calculating the trigger rate. This acts as a form of “fee” that the insurance company charges.
Here’s what the formula would look like.
Trigger Rate = the lesser of the ((Participation Rate x Index Performance) – Spread) or the Cap Rate
During years of robust market performance, trigger rates for indexed annuities may be higher, presenting greater potential returns for annuity holders. Conversely, during years of weak or negative market performance, trigger rates may be lower or even zero, restricting the potential returns.
Benefits of Trigger Rates in Annuities
Trigger rate annuities can offer a unique combination of guaranteed returns and the potential for higher growth. (You will want to check the annuity contract to make sure there’s a guaranteed minimum rate despite index performance.) This makes them an attractive option for those seeking a balance between security and opportunity in their retirement planning.
In addition to the guaranteed minimum return, trigger rate annuities also offer the potential for higher returns when the market performs well. These annuities can be tied to various market indices, such as the S&P 500, Dow Jones Industrial Average or NASDAQ Composite Index. Market indices are essentially a collection of stocks or other securities that represent a particular market or sector.
Drawbacks and Limitations of Trigger Rate Annuities

While trigger rate annuities can provide a balance between growth potential and downside protection, they also carry several limitations. One of the main drawbacks is that no interest is credited if the benchmark index fails to meet the trigger rate during a given period. Even if the index gains slightly, investors may earn nothing for that term. This can reduce the cumulative value of the contract over time.
Although the principal is typically protected from losses, the absence of growth in multiple periods can erode purchasing power, particularly during times of modest or inconsistent market performance.
Another limitation is that insurance companies may reserve the right to adjust trigger rates, participation rates or caps periodically. These adjustments are often based on market interest rate changes or the insurer’s internal financial conditions. Over time, lower trigger rates or more restrictive caps can reduce the annuity’s ability to capture meaningful returns from the market. Because the investor has little control over these changes, future growth potential can be uncertain. This makes it important for annuity holders to review their contracts regularly and understand how rate adjustments may impact their overall performance.
Trigger rate annuities also limit participation in market upswings. Even when the underlying index performs well, the credited interest is constrained by the pre-set trigger formula and potential cap rates. This means investors may not fully benefit from strong bull markets. This could make total returns lower than those from direct investments in stocks or mutual funds. While the structure offers peace of mind through guaranteed minimums and protection from loss, it trades away some of the higher upside available in more market-sensitive products.
Liquidity is another concern. Like most annuities, trigger rate products typically impose surrender charges for early withdrawals made within the first several years of ownership. Accessing funds before the end of the surrender period can result in penalties and may also trigger income taxes on earnings. These restrictions make trigger rate annuities less flexible than other investment options. This is particularly important for individuals who may need access to cash for emergencies or changing financial circumstances.
How to Use a Trigger Rate Strategy
A trigger rate strategy is an annuity feature that offers the potential for higher interest earnings if a specified benchmark index, such as the S&P 500, performs well enough to reach a predetermined “trigger rate.” If the index meets or exceeds the trigger rate, the annuity pays a higher interest rate for that term.
This strategy can provide investors with the opportunity to benefit from strong market performance while still enjoying the protection of a guaranteed minimum return.
To implement a trigger rate strategy, follow these steps:
- Research types of annuities that offer a trigger rate feature and compare the trigger rates, associated interest rates and terms offered by different providers.
- Compare expenses and fees attached with annuity products when deciding. You may want to consult a financial advisor to see how it fits into your overall financial plan.
- Choose a reputable insurance company and carefully review the annuity contract to understand the specific terms and conditions.
- Once invested, monitor the performance of the selected index relative to the trigger rate.
- Consider adjusting your strategy if market conditions change significantly.
- Regularly review your annuity statements to ensure interest is correctly credited based on the trigger rate performance.
And remember that while trigger rate strategies offer the potential for higher returns compared to traditional fixed annuities, they can also have their drawbacks.
Bottom Line

A trigger rate is a predetermined threshold that a benchmark index must reach for the annuity to credit a higher rate of interest. This unique feature allows investors to benefit from strong market performance while still enjoying a guaranteed minimum return. It’s important to consider the interplay between the trigger rate, participation rate, cap rate and spread. Doing so can help investors make informed decisions about whether an indexed annuity aligns with their goals and risk tolerance.
