An equity-indexed annuity, also known as a fixed-indexed annuity, is a retirement product designed to offer a balance between security and growth potential. It functions as a hybrid between fixed and variable annuities, providing a minimum guaranteed return (like fixed annuities) while tying part of your earnings to the performance of a market index (like variable annuities).
Because of this structure, equity-indexed annuities typically appeal to retirement savers who want greater growth potential than traditional fixed annuities without taking on full market risk. In rising markets, they can offer more upside than a fixed annuity. In downturns, they can also provide downside protection. But the structure can be complex and is subject to caps, fees, and limitations that are important to understand before committing.
This article will explain what equity-indexed annuities are, how they can grow, and whether they’re a smart fit for your retirement goals.

An equity-indexed annuity (EIA) is a type of fixed annuity that links your interest earnings to the performance of a market index. This structure protects your principal contribution from stock market losses, but you won't earn dividends or full returns. Instead, the insurer may caps your earnings based on a portion of the index’s gains, known as a participation rate.
In plain terms:
This makes EIAs a popular middle-ground strategy: You give up some of the upside in exchange for downside protection and guaranteed income options in retirement.
EIAs are typically linked various indexes such as the S&P 500 but depending on the product, they may offer other indexes like the Nasdaq Composite and Dow Jones Industrial Average.
These types of annuities can grow interest based on stock market index performance and guaranteed interest protections. But how much you earn with an EIA — and when — depends on a few key features. Depending on the annuity there are a few different ways in which interest is credited:
An insurer calculates and can pay interest to your annuity based on the crediting method the company or you decides to use. Common approaches include:
Each method determines when you receive interest and how much you earn over time. Your EIA won't realize the stock market's maximum return, but it does offer the potential for steady growth with downside protection and can offer a predictable minimum return, even when the market underperforms.
Equity-indexed annuities can work for people who want the potential for higher interest than a fixed annuity can offer — without being fully exposed to stock market risk. That balance of growth and protection is the appeal. But like any financial product, EIAs come with trade-offs.
EIAs may work wellas part of a comprehensive retirement strategy that focuses on ensuring you don’t outlive your money. Here are their main advantages:
Despite the upsides, EIAs may not be the best option for long-term savers. Consider the following disadvantages:
An equity-indexed annuity could be a fit if you’re a conservative-to-moderate investor seeking a blend of market upside and principal protection.
For example, the Gainbridge OneUp™ is a five-year fixed-indexed annuity that credits your account with up to 60% of the S&P 500's gains alongside principal protection. It can be ideal if you want more growth potential than a fixed annuity without exposing your base contribution to market decline.
The type of annuity you go with should align with your goals. Choose the structure that matches your appetite for returns, desire for security, and need for liquidity.
