How long your annuity lasts depends on the type you buy
An annuity's duration is determined by the contract you sign with the insurance company, not by how long you live or how much money you put in. Some annuities pay you for the rest of your life no matter how long that is. Others pay for a set number of years — 10, 20, or 30 — and then stop. A third type pays as long as you live, but guarantees a minimum number of payments to your beneficiary if you die early. The length you choose affects how much each payment will be.
The insurance company calculates your payment amount based on actuarial tables that estimate how long people in your age group typically live. If you choose lifetime payments, the company spreads your money across a longer expected period, so each check is smaller. If you choose a 10-year payout, the company divides your money across fewer years, so each check is larger. You decide which trade-off makes sense for your situation before you buy.
Key Takeaways
- A life annuity pays you monthly or quarterly for as long as you live, regardless of how long that is or whether you outlive the company's predictions.
- A term-certain annuity pays for a fixed period — typically 10, 15, 20, or 30 years — and then stops, even if you are still alive.
- A life annuity with period certain guarantees a minimum number of payments; if you die before that period ends, your beneficiary receives the remaining payments.
- Your monthly payment amount is locked in when you buy the annuity and does not change based on market performance or how long you actually live.
- Once you start receiving payments, you cannot change the payout duration or get your remaining balance back as a lump sum.
Life annuities: payments for as long as you live
A life annuity (also called a straight life annuity) pays you a fixed amount each month for the rest of your life. The payments stop when you die. This is the simplest and usually the highest monthly payment, because the insurance company does not have to set aside money for a beneficiary if you die early.
The trade-off is that if you die one year after buying the annuity, your beneficiary receives nothing. The insurance company keeps the remaining balance. This makes a straight life annuity risky if you have dependents or if you die younger than expected. Many people avoid this type for that reason.
Life annuities are common for people who have no dependents, who are in good health and expect to live into their 90s, or who want the highest possible monthly income. The payment is may provide by the insurance company's claims-paying ability, not by a government fund.
Term-certain annuities: payments for a fixed number of years
A term-certain annuity pays you a fixed amount each month for a set period — usually 10, 15, 20, or 30 years. After that period ends, payments stop, even if you are still alive. If you die before the period ends, your beneficiary receives the remaining payments in a lump sum or as continued monthly payments, depending on the contract.
Term-certain annuities are useful if you need income for a specific purpose — to bridge the gap until Social Security starts, to cover a mortgage that will be paid off in 15 years, or to fund a child's education. They also protect your beneficiary: if you die in year 3 of a 20-year contract, your estate or named beneficiary gets the value of the remaining 17 years of payments.
The monthly payment is higher than a life annuity would be, because the insurance company knows exactly when its obligation ends. However, you bear the risk that you will outlive the payments. If your 20-year term ends at age 85 and you live to 95, you have no income from that annuity for the last 10 years.
Life annuities with period certain: a hybrid approach
A life annuity with period certain combines the two types. You receive payments for life, but the insurance company guarantees a minimum number of payments — typically 10, 15, or 20 years. If you die before that period ends, your beneficiary receives the remaining payments.
For example, a life annuity with 15 years certain pays you monthly for life. If you die in year 8, your beneficiary receives payments for the remaining 7 years. If you live past year 15, you continue receiving payments for life, and your beneficiary receives nothing after you die.
This type costs less per month than a straight life annuity (because the company may have to pay your beneficiary) but more than a term-certain annuity (because the company may have to pay you for 30+ years). It appeals to people who want lifetime income but also want to leave something to their heirs if they die early.
What happens if you die before the annuity ends
The outcome depends on your contract type. With a straight life annuity, your beneficiary receives nothing — the remaining balance stays with the insurance company. With a term-certain annuity or a life annuity with period certain, your beneficiary receives the remaining payments or their present value as a lump sum.
Some annuities include a refund feature, which guarantees that if you die, your beneficiary will receive at least the amount you paid in, minus any payments you already received. This costs more per month but protects against the risk of dying very early. Ask the insurance company whether your contract includes this before you buy.
You name your beneficiary when you set up the annuity. You can usually change the beneficiary later, but you cannot change the payout duration or switch to a different type of annuity once payments have started.
How inflation affects the length of your annuity's purchasing power
Your monthly payment amount is fixed when you buy the annuity and does not increase. This means that if you receive $2,000 per month in year one, you will receive $2,000 per month in year 20, even though inflation will have reduced what that money can buy.
Some annuities offer a cost-of-living adjustment (COLA), which increases your payment by a set percentage each year or ties it to inflation. A COLA annuity costs more upfront (your first payment is lower), but your purchasing power is protected over time. This matters most if you are buying a life annuity and expect to receive payments for 30 or 40 years.
Without a COLA, a life annuity that lasts 40 years will feel like it is paying less and less as time goes on. With a COLA, your payment grows, but you start with a smaller amount. You decide which trade-off suits your situation before you buy.
Frequently Asked Questions
Can I change my mind about the payout duration after I buy the annuity?
No. Once you have signed the contract and payments begin, you cannot switch from a life annuity to a term-certain annuity, add a period certain, or change the length of the period. The duration is locked in. If you are unsure, take time to decide before you buy.
What if I need a lump sum instead of monthly payments?
Most annuities do not allow you to withdraw the remaining balance as a lump sum once payments have started. Some contracts include a small withdrawal allowance (typically 10% per year), but this is rare. If you think you might need access to the money, discuss this with the insurance agent before you buy.
Does the insurance company have to keep paying if it goes out of business?
Each state has a guaranty fund that protects annuity payments if an insurance company fails. The coverage limit varies by state but is typically $250,000 or more per person per company. This is not a government may provide — it is a fund supported by insurance companies themselves. Ask the company about your state's guaranty fund coverage.
Is a life annuity a good choice if I have a family history of living into my 90s?
A life annuity may make sense if you expect to live well past age 85 and have no dependents who need an inheritance. If you have dependents, a life annuity with period certain or a term-certain annuity protects them. If you are unsure about your health or longevity, a hybrid option is usually safer than a straight life annuity.
Can I buy multiple annuities with different durations?
Yes. Some people buy one annuity that pays for 10 years to cover when ready expenses and another that pays for life to cover expenses after age 75. This approach lets you customize your income stream, but each annuity has its own fees and terms. Discuss your goals with a financial professional before buying multiple contracts.
