An annuity is not the right move for everyone, and the decision depends on your age, how much money you have, and what you need the money to do

An annuity converts a lump sum of money into regular payments that last for a set period or for your whole life. The appeal is straightforward: you trade liquidity for certainty. You know exactly what you will receive each month. The catch is equally straightforward: once you hand over the money, you cannot get it back, and if you die soon after buying the annuity, your heirs may receive nothing.

Whether you should buy one depends on three concrete facts: how old you are, whether you have other sources of income you can count on, and whether you can afford to lock money away. If you are in your 50s with a pension and Social Security coming, an annuity may be unnecessary. If you are 75 with no pension and savings you need to stretch across 20 or 30 years, an annuity may solve a real problem. The decision is not about whether annuities are good or bad in general—it is about whether this particular tool fits your particular situation.

Key Takeaways

  • An annuity makes the most sense if you are in your mid-70s or older, have a large sum to invest, and want to stop worrying about whether your money will last.
  • If you already receive a pension or have substantial other retirement income, an annuity may duplicate protection you already have.
  • Annuities lock your money away permanently, so you should only buy one with funds you will not need for emergencies or unexpected costs.
  • The type of annuity matters enormously: when ready annuities are simpler and cheaper, while variable and indexed annuities carry higher fees and more complexity.
  • You should get quotes from at least three different insurance companies before deciding, because the monthly payment you receive varies significantly by company.

When your age makes an annuity worth considering

The older you are when you buy an annuity, the more sense it makes financially. An insurance company prices an annuity based on how long they expect to pay you. If you buy at 55, they expect to pay for 30 or 40 years. If you buy at 80, they expect to pay for 10 or 15 years. That means the monthly payment is much higher relative to what you put in.

Most financial advisors suggest that annuities become worth considering around age 70 or 75, when you have a clearer picture of your life expectancy and when the monthly payment is substantial enough to matter. Before 65, you usually have other options that give you more flexibility. After 80, an annuity can be one of the few ways to turn a large sum into may provide income without managing investments yourself.

Your health also matters. If you have a serious illness that shortens your life expectancy, an annuity is a poor trade—you may not live long enough to recover your initial investment. If you are in good health and your family history suggests longevity, an annuity protects you against the risk of living longer than your money lasts.

How much may provide income you already have

Before you buy an annuity, list every source of income you will receive in retirement that you cannot control or lose: Social Security, a pension from a former employer, rental income from property you own outright. Add those up. That number is your may provide baseline income.

Now estimate your monthly expenses in retirement. Subtract your may provide baseline from that number. The gap is what you need to cover with savings, investments, or an annuity. If the gap is small—say $500 or $1,000 a month—an annuity may be overkill. If the gap is large and you have a lump sum that could cover it, an annuity becomes practical.

The reason this matters is that an annuity is insurance against outliving your money, not a way to get rich. If you already have enough may provide income to cover your basic needs, an annuity does not add much value. If you have a gap that worries you, an annuity fills it.

Whether you can afford to lock money away

An annuity is permanent. Once you buy it, you cannot change your mind and get your money back. Some annuities allow you to withdraw a small percentage each year without penalty, but most do not. This means you should only buy an annuity with money you are certain you will not need for emergencies, medical costs, or helping family members.

A common mistake is buying an annuity with your entire savings. If you have $300,000 saved and you put all of it into an annuity, you have no cushion left. A major car repair, a dental emergency, or a health crisis that is not covered by insurance can force you to take a withdrawal penalty or borrow money at high interest. A safer approach is to buy an annuity with part of your savings—perhaps 40 or 50 percent—and keep the rest in liquid investments you can access.

This is especially important if you are younger than 70. The longer your time horizon, the more likely you are to face an unexpected expense that requires access to cash.

when ready annuities versus complex annuities

An when ready annuity is straightforward: you give an insurance company a lump sum, and they send you a fixed payment every month for life. There are no moving parts, no investment choices, no fees hidden in the fine print. You know exactly what you will receive. The insurance company bears the investment risk and the longevity risk.

A variable annuity ties your monthly payment to the performance of investments you choose—stocks, bonds, mutual funds. If those investments do well, your payment increases. If they do poorly, your payment decreases. Variable annuities also carry annual fees that can run 1 to 3 percent of your account value, which is substantially higher than the cost of buying index funds on your own. Unless you have a specific reason to want variable payments, an when ready annuity is simpler and usually cheaper.

An indexed annuity ties your payment to a stock market index like the S&P 500, but with a cap on how much you can gain and a floor that protects you from losses. These sound appealing but are complex, expensive, and often sold with high commissions. The insurance company's marketing materials make them sound better than they usually are in practice.

If you decide an annuity makes sense for you, start by getting quotes for when ready annuities from at least three different insurance companies. Compare the monthly payment each one offers for the same lump sum. The differences are often substantial—sometimes 10 or 15 percent—so shopping around matters.

What happens to your money if you die soon

A basic when ready annuity pays you for life, and when you die, the payments stop. If you die one month after buying the annuity, your heirs receive nothing, and the insurance company keeps the rest of your money. This is the trade-off for getting a higher monthly payment.

You can reduce this risk by choosing a period-certain annuity, which guarantees payments for a set number of years—usually 10, 15, or 20 years—even if you die. If you die before that period ends, your heirs receive the remaining payments. The cost is a lower monthly payment, because the insurance company's risk is lower.

A joint-and-survivor annuity continues payments to your spouse after you die, usually at a reduced rate. This protects your spouse but lowers your monthly payment while you are both alive. If you are married and your spouse has little income of their own, this option is worth the cost.

Before you buy, think about what would happen to your spouse or dependents if you died in the first year. If they would struggle, a period-certain or joint-and-survivor option is worth the lower payment. If they have other income and do not depend on you, a straight life annuity gives you the highest monthly payment.

The role of inflation in your decision

Most when ready annuities pay the same amount every month for the rest of your life. If you buy an annuity at 75 and live to 95, the $2,000 monthly payment you receive at 95 will buy far less than it did at 75, because inflation erodes its purchasing power.

Some annuities offer inflation-adjusted payments, which increase each year by a set percentage or by the actual inflation rate. These cost more upfront—your initial monthly payment is lower—but your payment keeps pace with rising costs. Whether this makes sense depends on your age and how long you expect to live. If you are 80 and expect to live to 90, inflation may not be a major concern. If you are 70 and expect to live into your 90s, inflation protection becomes more valuable.

Ask for quotes both with and without inflation adjustment. Compare the initial payment, the payment at age 85, and the payment at age 95 to see the real difference over time.

Frequently Asked Questions

Can I buy an annuity with money from my IRA or 401(k)?

Yes. You can roll money from a traditional IRA or 401(k) into an annuity without triggering taxes, as long as the annuity is held inside the IRA or 401(k). If you withdraw money first and then buy an annuity outside the retirement account, you will owe income tax on the withdrawal. Talk to a tax professional before moving retirement account money into an annuity.

What if the insurance company goes out of business?

Each state has a guaranty fund that protects annuity holders if an insurance company fails. The protection limit varies by state but is usually $250,000 or more per person per company. Before you buy, check your state's insurance department website to see what protection applies to you, and consider spreading large sums across multiple insurance companies.

Is there a penalty if I need to withdraw money early?

Most when ready annuities do not allow withdrawals at all—the money is gone once you buy the annuity. Some offer a small annual withdrawal right (often 10 percent of your account value per year) without penalty. If you withdraw more than that, you typically pay a surrender charge that can be 5 to 10 percent of the amount withdrawn. Read the contract carefully before you buy.

Should I buy an annuity if I have a lot of debt?

No. Pay off high-interest debt first. An annuity locks your money away, so if you still owe money on credit cards or loans, you are paying interest on one side while locking money away on the other. Once your debt is paid off and you have an emergency fund, then consider an annuity.

How do I know if a salesperson is pushing an annuity I do not need?

Annuities pay high commissions to the people who sell them—often 5 to 10 percent of the amount you invest. This creates an incentive to sell annuities even when they are not the best choice for you. If someone is pushing you to buy quickly, using pressure language, or suggesting you put all your savings into an annuity, get a second opinion from a fee-only financial advisor who does not earn commissions.
