A single life annuity pays guaranteed income for as long as one named person, the annuitant, is alive, and payments stop at that person's death even if it happens shortly after the contract starts.
What is a single life annuity?
A single life annuity is an income option that pays you for as long as one specific person, the annuitant, remains alive. The moment that person dies, the payments end completely, whether that happens decades into the contract or in the very first month. Because the insurance company is only insuring a single life expectancy instead of two, a single life payout produces the largest monthly check of any lifetime income structure.
How the payment amount is calculated
Carriers price a single life annuity using mortality tables alongside the annuitant's age, gender in most states, and the interest rate environment at the time of purchase. Age drives the math more than anything else. A 65-year-old man putting $100,000 into a single premium immediate annuity today might see roughly $580 a month for life, while a 75-year-old buying the identical contract would receive noticeably more, because the insurer expects to pay for fewer years. A 55-year-old would see a smaller check for the opposite reason.
Adding a period certain
Most carriers let you soften the all-or-nothing risk of a single life payout by adding a period certain, a guaranteed minimum stretch of payments, typically running 5, 10, 15 or 20 years. If you die before that window closes, whoever you named as beneficiary keeps collecting the remaining payments. Tacking a 10-year period certain onto a single life SPIA usually trims the monthly check by roughly 5% to 8%, in exchange for guaranteeing your heirs at least a decade of income if you pass away early.
Single life vs. joint and survivor
Choose single life when you are the only one who needs the income, or when your spouse already has separate guaranteed income of their own. Choose a joint and survivor annuity when both spouses depend on the same payments continuing. The right answer comes down to each spouse's full financial picture, not simply the household's total income today. Our immediate annuity calculator lets you compare single life, period certain and joint payout options side by side.
Frequently asked questions
What is a single life annuity?
It is a lifetime income option that pays you for as long as one named annuitant is alive. Payments stop entirely at that person's death, even if death occurs soon after the contract starts, which is why single life pays more per month than options covering two lives.
How does a period certain change a single life payment?
Adding a period certain, commonly 10 years, guarantees a minimum stretch of payments to your beneficiary if you die early, but it typically lowers your monthly check by roughly 5% to 8% compared with a pure single life payout.
When should you pick single life over joint and survivor?
Pick single life when you are the only person relying on the income, or your spouse already has separate guaranteed income. Pick joint and survivor when the household needs the payments to continue for whichever spouse lives longer.
