How a Lifetime Annuity Works and What You Receive Each Month

A lifetime annuity pays you a fixed amount every month for the rest of your life, no matter how long you live

A lifetime annuity is a contract with an insurance company where you give them a lump sum of money upfront, and they send you a regular payment every month until you die. The insurance company bets that you will not live as long as the average person in your age group; you bet that you will. If you live longer than expected, you win — the company keeps paying. If you die sooner, the company keeps what is left.

The monthly payment amount is fixed when you buy the annuity and never changes, even if inflation rises or interest rates fall. That predictability is the main reason people choose lifetime annuities: you know exactly what will arrive in your bank account on the same day each month, for as long as you live.

Lifetime annuities are different from other retirement income sources. Social Security also pays for life, but the government sets the amount and you do not control when you start. A pension works the same way — fixed payments for life, but your employer or union controls the terms. With a lifetime annuity, you decide how much to invest and when to start receiving payments, though an insurance company calculates what your monthly check will be.

Key Takeaways

• You pay an insurance company a lump sum once, and they send you the same monthly payment for the rest of your life, regardless of how long you live.
• The monthly payment is locked in when you buy the annuity and does not increase with inflation or change if interest rates move.
• If you die before receiving back the amount you paid in, most lifetime annuities do not refund the difference to your heirs unless you chose a refund option at purchase.
• The insurance company's financial strength matters because they must be able to pay you for decades; check their ratings before buying.
• Lifetime annuities work best for people who have other sources of income and want to may provide a portion of their retirement spending will never run out.

How the insurance company calculates your monthly payment

The insurance company uses three main factors to decide how much to send you each month: how much money you give them, how old you are when payments start, and current interest rates.

If you are younger when you buy the annuity, your monthly payment will be smaller because the company expects to pay you for more years. A 55-year-old who invests $100,000 will receive less per month than a 75-year-old who invests the same amount. The company also looks at interest rates — when rates are higher, they can earn more on your money, so they can afford to pay you more each month.

Your health and family history do not usually affect the payment amount in a standard lifetime annuity. Some insurance companies offer medically underwritten annuities, where they ask about your health and may pay you more if you have a condition that shortens life expectancy, but these are less common and cost more to set up.

What happens to your money if you die early

This is the biggest trade-off with a lifetime annuity. If you die one year after buying the annuity, the insurance company typically keeps the remaining balance. You do not get a refund, and your heirs receive nothing — unless you paid extra for a refund option when you bought the contract.

Some people add a period-certain option to their annuity, which guarantees payments for a set number of years (often 10 or 20 years) even if you die. If you choose a 10-year period-certain and die in year 3, your heirs receive the remaining 7 years of payments. This option lowers your monthly payment because the insurance company's risk is reduced.

Another option is a joint-and-survivor annuity, where payments continue to a spouse or named beneficiary for their lifetime after you die. This also reduces your monthly payment, sometimes significantly, because the company expects to pay two people instead of one.

The difference between lifetime annuities and other retirement income

A term annuity (or period-certain annuity) pays you for a fixed number of years — say, 20 years — and then stops, regardless of whether you are still alive. A lifetime annuity has no end date; it pays until you die. Term annuities usually offer higher monthly payments because the insurance company knows exactly when their obligation ends.

A variable annuity ties your monthly payment to the performance of investments you choose, so the amount can go up or down. A lifetime annuity payment never changes. Variable annuities are more complex and carry investment risk; lifetime annuities shift all the risk to the insurance company.

Social Security is similar to a lifetime annuity in that it pays for life, but you cannot control the amount or when you receive it (within a narrow window). A pension is also a lifetime payment, but your employer or union controls the terms. A lifetime annuity gives you control over how much to invest and when to start, but an insurance company controls the monthly amount.

When a lifetime annuity makes sense for your situation

A lifetime annuity works best if you have already saved enough to cover your basic living expenses and want to lock in a may provide income stream for the rest of your life. It is useful if you are worried about outliving your savings or if you do not want to manage investments in retirement.

A lifetime annuity is less useful if you need access to your money — once you buy it, you cannot get the lump sum back. It is also less useful if you have serious health problems and expect to die soon, because you may not receive back what you paid in. If you have a family history of longevity and expect to live into your 90s, a lifetime annuity can be a good hedge against that risk.

Many financial advisors suggest using a lifetime annuity for only a portion of your retirement savings — enough to cover essential expenses like housing, food, and utilities — and keeping the rest in investments you can access or adjust as needed.

Checking the insurance company's ability to pay

Because an insurance company must send you payments for potentially 30 or 40 years, their financial strength matters. If the company fails, your payments are at risk. Before buying a lifetime annuity, check the insurance company's ratings from agencies like A.M. Best, Moody's, or Standard & Poor's. These ratings tell you how likely the company is to meet its obligations.

Most states also have a guaranty association that protects annuity holders if an insurance company becomes insolvent. The protection amount varies by state but is often $250,000 per person per company. This is not a may provide that you will receive all your payments, but it does provide a safety net. You can find your state's guaranty association through the National Organization of Life & Health Insurance Guaranty Associations (NOLHGA) website.

Taxes on lifetime annuity payments

How you are taxed depends on where the money came from. If you bought the annuity with after-tax money (money you already paid income tax on), part of each payment is a return of your original investment and is not taxed; the rest is taxed as ordinary income. If you bought it with pre-tax money from an IRA or 401(k), the entire payment is taxed as ordinary income.

The insurance company will send you a 1099-R form each year showing how much of your payment is taxable. You report this on your tax return. If you bought the annuity before age 59½ with pre-tax retirement money and start taking payments before that age, you may owe an additional 10 percent early withdrawal penalty, though some exceptions explore.

Frequently Asked Questions

Can I change my mind after I buy a lifetime annuity?

Most lifetime annuities cannot be cancelled or exchanged once you buy them. Some contracts include a short free-look period (usually 10 to 30 days) where you can return the annuity and get your money back. After that window closes, you are locked in. Always read the contract terms before you commit.

What if inflation rises and my payment stays the same?

Your purchasing power will decline because your monthly payment does not increase. Some annuities offer an inflation-adjusted option that starts with a lower payment but increases by a set percentage each year. This costs more upfront but protects you against rising prices over time.

Do I have to buy a lifetime annuity with a lump sum, or can I use monthly payments?

Most lifetime annuities require a single lump-sum payment upfront. Some insurance companies offer deferred annuities, where you make payments over time and then start receiving income later. These are less common and have different rules, so ask your insurance agent about the options available.

What happens if the insurance company goes out of business?

Your state's guaranty association will typically step in and continue your payments up to the state's protection limit, often $250,000. If your annuity is worth more than that, you may lose the excess. This is why checking the insurance company's financial ratings before you buy is important.

Is a lifetime annuity the same as an when ready annuity?

An when ready annuity is one where you pay a lump sum and start receiving payments right away, usually within 30 days. A lifetime annuity describes how long the payments last — for your entire life. Most when ready annuities are also lifetime annuities, but you can have a lifetime annuity that is deferred (payments start later) instead of when ready.
