How does an annuity work?
If you've been hearing more about annuities lately, you're not alone. As more Americans consider how to make their retirement savings last, annuities have become an increasingly common part of financial planning conversations. According to the 2025 Protected Retirement Income and Planning Study conducted by the Alliance for Lifetime Income by LIMRA, 54% of Baby Boomers and Gen X investors say they're worried about outliving their assets in retirement.¹ This worry brings a curiosity about how annuities actually work.
What is an annuity?
An annuity is a contract between you and an insurance company. You make a payment, either as a lump sum or through a series of contributions, and in return, the insurer agrees to pay you back, either right away or at a future date of your choice. Understanding the basics is a good step toward a more productive conversation with your financial professional.
Annuities are designed to supplement other retirement income sources—like Social Security, personal savings and pensions. The amount you receive depends on factors like the type of annuity, how much you invest and prevailing interest rates. Because there are several types, each with its own features and benefits, working with a financial professional can help you determine which might work best based on your specific needs.
Types of annuities
There are several types of annuities, each designed to address different stages of life and varying degrees of risk tolerance. Variable annuities carry more risk but offer the potential for more growth, while registered index-linked annuities (RILAs) offer levels of protection alongside options for growth. For those seeking less market exposure, fixed index annuities provide downside protection, and fixed annuities offer steady growth potential through a fixed rate of return.
Key benefits of an annuity
With fewer traditional pensions available, creating your own reliable income stream in retirement has become more important than ever. Annuities can help address that need in a few beneficial ways.
Tax deferral:* any gains within an annuity are not taxed until you begin taking withdrawals, which means your money has the opportunity to grow without being reduced by taxes along the way. The higher the amount you start with, the more potential it has to grow over time.
Guaranteed† lifetime income:‡ for those who want income that lasts no matter how long they live, some annuities offer guaranteed lifetime income through an add-on benefit§ available for an additional cost. It's a feature that directly addresses one of the most common concerns in retirement planning—the possibility of outliving your savings.
Death benefit protection: for those looking to leave a legacy, some annuities offer an add-on death benefit for an additional cost. It can be a way to make sure the people you care about are taken care of even after you're gone.
How annuities work across different stages of life
No two investors are the same, and the role an annuity plays in a retirement plan often depends on where you are in life. Annuities are designed to meet different needs at different life stages, so understanding the variety of ways they can work is a useful place to start.
Stage 1: growth
Accumulation stage: pre-retirement, early in career
In the earlier stages of your career, retirement may feel far away—but the decisions you make now can have a lasting impact. An annuity at this stage is primarily for growth and accumulation, giving your money the opportunity to grow tax-deferred over time. This stage may resonate if you:
- Are focused on building enough to retire comfortably.
- Have an IRA or 401(k) and are looking for additional ways to save.
- Feel uncertain about investing in the market and want some level of protection.
- Are balancing retirement savings with other financial priorities like educational planning.
Stage 2: guarantee
Income distribution stage: entering retirement
As retirement approaches (or begins), the conversation starts to shift from building wealth to protecting what you have and generating a reliable income. For those without a pension or a guaranteed income stream, an annuity can help fill that gap. This stage may resonate if you:
- Don't have a pension or a guaranteed income source beyond Social Security.
- Are looking for a reliable income stream to supplement your savings.
- Want to manage how taxes will affect your nest egg in retirement.
Stage 3: giving
Legacy protection stage: Fully in retirement
Once fully in retirement (whatever that looks like for you), priorities often shift toward what you want to leave behind. An annuity with a death benefit can help make sure the people you care about are taken care of, even if you don't need to draw income every year. This stage may resonate if you:
- Want to leave assets to children, grandchildren or a charity.
- Prefer the option to take income without being required to do so annually.
- Have a diverse** portfolio and are primarily focused on legacy planning.
Is an annuity right for you?
Annuities can be a valuable part of a retirement income plan, but they aren't right for every investor or every situation. Like most financial products, they come with costs worth understanding. You'll typically pay a contract charge related to the product you purchase, along with additional charges for any add-on benefits you choose. Depending on the type of annuity, your financial professional may also charge an advisory fee. If you think you may need access to your funds before a contract's surrender period ends, it's important to discuss what early withdrawal fees could cost.
Many people find real value in what annuities can offer: stability, income protection and options that can be tailored to where you are in life. Whether or not an annuity is the right fit for you, the best place to start is a conversation with a financial professional who can evaluate your full retirement picture and help you determine whether an annuity supports your personal retirement goals.
