Demystifying annuities: Fixed, variable and beyond

A clear look at how annuities work and when they might fit into a broader retirement income strategy.

5 min read

Summary

  • An annuity is a contract, usually with an insurance company, that can help your savings grow and, if you choose, turn your money into a series of payments that will last as long as you live.
  • Fixed annuities provide guaranteed growth and predictable income.
  • Variable annuities provide growth potential with market exposure, but also come with the risk of a market downturn.
  • Index annuities can serve as a middle ground between fixed and variable.
  • Common choices in annuity payouts include when your income begins (immediately or deferred to a later date), how long your income will last (for your lifetime or for a fixed period), and how you access the annuity (through a workplace retirement plan or on your own).
  • Decide if an annuity is right for you by considering how close you are to retirement, how you feel about market uncertainty, how involved you want to be in managing your money, and what your other retirement income sources will be.

For millions of people, retirement isn’t a finish line, it’s a question mark. Will my savings last? What happens if the market drops at the wrong time? What if I run out of money?

These questions are more common than you might think. In fact, nearly two-thirds of Americans say retiring between 65 and 70 is unattainable.1 When retirement feels uncertain, many people look for ways to create more stability. That’s where annuities frequently enter the conversation.

Annuities can sound complicated at first. The terminology can be technical, and there are several types. But the core idea is straightforward: in retirement, annuities are designed to help turn savings into income.

What is an annuity?

An annuity is a contract, usually with an insurance company, that can turn your savings into income. In general, annuities work in three stages:

  • The saving stage: You invest money that can grow over time.
  • The conversion stage: You convert some or all of your savings into income—this is called annuitization.
  • The payout stage: You can begin receiving income (aka retirement checks).

The three main types of annuities

Beyond the default investment, most employer plans also offer choices that let you build your own investment mix. Common investment types (also known as “asset classes”) include:

  • Fixed annuities
  • Variable annuities
  • Index annuities

The differences largely come down to how your money grows and how much market risk you take on. Fixed and variable annuities are the most common annuities people compare, so we’ll focus on these.

Fixed annuities: guaranteed growth and predictable income

With a fixed annuity, the insurance company agrees to pay a set interest rate during the saving phase and, if you choose, provide a steady stream of income in retirement. They can do this because instead of investing your money and paying you based on growth, your payments come from a pool of money the company has in reserve. Like all insurance products, the ability to satisfy guarantees is subject to what’s called the “claims-paying ability” of the insurance company that issues the contract. TIAA is proud to be one of only three insurance groups in the United States to currently hold the highest possible rating from all four leading insurance company rating agencies for its stability, claims-paying ability and overall financial strength.

Fixed annuities offer certainty. As you save, you know exactly how fast your money will grow. During retirement, you know your payments will remain steady for the rest of your life. Since annuities are designed for stability, growth may be more modest compared to long-term market investing. But that’s the point: a fixed annuity provides predictability. Your balance increases every day no matter what.

In a retirement plan, fixed annuities provide security because you know you’ll always have money coming, no matter how long you live.

Variable annuities: growth potential with market exposure

Variable annuities invest your money in the market. Since the market rises and falls , both your growth rate and the size of your retirement payouts can vary (hence the name “variable annuity”). You don’t receive guaranteed growth or predictable retirement income like with a fixed annuity. But you gain the potential for higher returns and larger payouts. For people comfortable with risk and focused on growth, this trade-off can be appealing.

In a retirement plan, variable annuities can help your retirement savings keep up with inflation. If prices rise over time, your dollars may not stretch as far in the future. Variable annuities may provide growth that can help address that concern, but the results aren’t guaranteed.

Fixed and variable annuities: A combined approach

Some people use both. A fixed annuity can provide dependable income, while a variable annuity offers growth potential. Together, they can balance security and opportunity. In fact, TIAA invented the variable annuity in 1952 for just this reason.

Index annuities: a middle-ground option (in some cases)

An index annuity is often described as sitting between fixed and variable annuities. Index annuities are linked to the performance of a market index (such as the S&P 500). But unlike direct stock investing, index annuities may limit how much you can earn or lose.

In a retirement plan, an index annuity can combine some of the benefits of fixed and variable annuities. Some index annuity contracts protect you from certain losses, but since they’re tied to a stock-market index, they have more growth potential than fixed annuities.

Annuitization: An important step to receive lifetime income

A commonly overlooked but important aspect of annuities is that payouts don’t automatically start when you retire—you have turn them on through a process called “annuitization.” If you don’t activate payments your money stays in the annuity with the same growth-rate or investments it had before you retired. You can still withdraw money, but you won’t receive regular income.

If you decide to annuitize (i.e. turn on payments) you’ll likely have choices about how you’ll receive your payouts, for example, when you want payments to start, how much of your savings you want to turn into income, and who receives the money (just you, you and a spouse or partner).

If your annuity is inside a workplace retirement plan or IRA, your annuity payments count towards your required minimum distributions (RMDs), which can make these annual requirements easier to fulfill.

The important thing to remember is that you have choices—annuitization isn’t an all-or-nothing decision. You can annuitize all of your savings or just part. Or you can choose to leave the money in your account.

Common options in annuity payouts: immediate vs deferred, lifetime income vs fixed period & in-plan vs retail

In addition to the three main categories—fixed, variable, and index—annuities are often described using additional terms. These typically refer to the payouts you receive if you decide to annuitize.

Immediate vs. deferred annuities

This refers to when income begins.

  • Immediate annuity: Payments start relatively soon after purchase.
  • Deferred annuity: Your money grows for a period of time before income begins.

Deferred annuities often suit people who are still working and planning ahead. Immediate annuities are more common for those near or in retirement.

Lifetime vs. fixed period annuities

This refers to how long your income lasts.

  • Lifetime: Income continues as long as you live.
  • Fixed period: Income lasts for a set amount of time, such as 10 or 20 years.

Lifetime income can help protect against longevity risk—the chance of outliving your money. Fixed period income may appeal to someone who want predictable payments during a set period of time, for example, before Social Security or other income begins.

In-plan vs. retail annuities

This refers to how you purchase your annuity.

  • In-plan annuity: Access through an employer retirement plan like a 401 (k) or 403 (b).
  • Retail annuity: Access through an individual account like an IRA.

How you access an annuity can affect costs, options, and how it fits into your overall financial plan. Annuities do not provide any additional tax-deferral advantage over other types of investments within a qualified plan.

How to decide whether an annuity is right for you

Annuities are tools, not one-size-fits-all solutions. The best way to think about them is as one option among many. Here are a few questions that can help guide your decision.

How close are you to retirement?

Time matters. People who are decades away from retirement may focus more on growth and saving. People closer to retirement may focus more on protecting what they’ve built and turning some of their savings into income.

How do you feel about market uncertainty?

Some people can tolerate market ups and downs without losing sleep. Others prefer stability. If market swings make you uneasy—especially if you’ll need income soon—a fixed annuity or other stable option may feel more comfortable. If you’re comfortable with risk and want growth potential, you may prefer investment-based strategies, including variable annuity options.

Do you want to manage your retirement income yourself?

Some people enjoy being hands-on: monitoring investments, adjusting withdrawals, and staying engaged with financial planning. Others prefer a more structured plan that requires less decision-making. Annuities may appeal to people who want fewer moving parts.

What are your other investments and retirement income sources?

While you’re saving, think about what other investments you have, and the role an annuity would pay in your portfolio (your total mix of investments). Consider where your retirement income will come from: Social Security, workplace plans, IRAs, savings and more. An annuity may complement these sources by adding predictable or variable income.

Take action: next steps

If you’re curious whether an annuity fits your retirement strategy, start here.

1. Find out if you already have an annuity.

Some workplace plans come with an annuity already built in. Employers are beginning to include annuities to help provide stability during the saving phase and the opportunity for guaranteed income during retirement. If you’re a TIAA participant, you may already be saving in annuity. Log in to your account to find out.

2. Get clear on your income needs

A helpful starting point is to estimate what your basic monthly expenses might be in retirement, and what retirement income sources you already expect (like Social Security). This can help you understand whether you may need additional predictable income.

3. Ask questions before making decisions

If you speak with a financial professional, ask questions like:

What problem is this annuity meant to solve?

  • When does income begin?
  • What parts are guaranteed, and what parts are not?
  • What happens if I need access to money early?
  • What fees or costs apply?

Even if you choose not to purchase an annuity, these questions can sharpen your thinking.

4. Use tools and guidance available through your plan

Many employer retirement plans offer education tools, retirement income calculators, and access to guidance. These resources can help you understand how different income options might fit together.

5. When you’re ready to turn on retirement payments, consult a professional

The process of converting some or all of your annuity savings into regular payouts (called annuitization) can be complex. Some companies offer specialized help to guide you through the process.
