How is an immediate annuity payout calculated?
An insurer prices a SPIA from three things: how long it expects to pay (your age and sex against its mortality table), the interest it can earn on your premium while it pays you, and its costs. Older buyers get more per month because fewer checks are expected. Women get less than men of the same age because they live longer on average. A payout rate is not an interest rate: most of each early check is your own principal coming back.
This calculator does not run its own actuarial model. It reads the survey table for your age, sex and option, multiplies by your premium ÷ $100,000, and interpolates between surveyed ages.
Worked example: what does a 70-year-old woman get for $250,000?
Survey average for a 70-year-old woman, life-only: $662 a month per $100,000. Scaled to $250,000 that is $1,655 a month, or $19,860 a year. At that rate the checks add up to her $250,000 after about 12.6 years, around age 83. With 10 years certain the average drops to $1,620 a month, and if she dies in year three her beneficiary receives the remaining seven years of payments.
Which payout option should I pick?
- Life only pays the most and stops at death. Nothing goes to heirs.
- Life with 5, 10, 15 or 20 years certain guarantees payments for that period even if you die early. At 65 the 10-year guarantee cost a man about $13 a month on average; at 80 it cost $139.
- Cash refund pays a beneficiary a lump sum of any premium not yet paid back. Installment refund does the same through continued payments.
Are immediate annuity payments taxable?
Bought with IRA or 401(k) money, every payment is ordinary income. Bought with after-tax money, each payment is split by an exclusion ratio (IRC §72(b)): the return-of-premium part is tax-free until you have recovered your premium, and the rest is ordinary income. The insurer reports it on Form 1099-R. More: non-qualified annuity taxes.
What are the downsides of an immediate annuity?
- It is usually irrevocable. Once payments start you generally cannot get the lump sum back.
- Most payouts are level, so inflation erodes them over a 20-year retirement.
- Payments depend on the insurer; they are guaranteed by the issuing insurer’s claims-paying ability, backed up to limits by your state guaranty association.
- Life-only leaves nothing to heirs if you die early.

What the guarantee is. Fixed annuity and MYGA guarantees are guaranteed by the issuing insurer’s claims-paying ability. Annuities are insurance contracts, not bank deposits: they are not FDIC-insured, not bank-guaranteed and not a CD. State guaranty association protection has limits and varies by state. Surrender charges and, on many contracts, a market value adjustment apply to withdrawals above the free amount during the surrender period. Withdrawals of earnings are taxed as ordinary income and, before age 59½, may also owe a 10% federal additional tax (IRC §72(q)).

Frequently asked questions
How much does a $100,000 annuity pay per month for life?
In the September 9, 2026 ImmediateAnnuities.com survey, life-only: $639 a month average for a 65-year-old man and $612 for a woman; $714 and $662 at 70; $831 and $773 at 75. Best quotes ran higher. These are illustrative survey figures, not quotes.
How much does a $500,000 immediate annuity pay?
Scale the $100,000 figure by five: a 65-year-old man averaging $639 per $100,000 would get about $3,195 a month life-only, based on the September 9, 2026 survey. Large premiums can sometimes be split across insurers to stay within state guaranty association limits.
Why do women get lower annuity payouts?
Women live longer on average, so the insurer expects to pay them for more years and pays less per month for the same premium.
Can I get my money back from an immediate annuity?
Usually not. Most SPIAs are irrevocable once issued. A period-certain or refund option protects heirs, and some contracts allow a limited commutation of guaranteed payments, but you should treat the premium as spent.
Is an immediate annuity guaranteed?
Payments are guaranteed by the issuing insurer's claims-paying ability, and state guaranty associations provide backup coverage up to limits that vary by state. It is not FDIC insurance.
