The annuity payout calculator shows how much income a lump sum can generate over a fixed period. Enter your principal, interest rate, and payout duration to see the regular payment amount. It is one of the most important calculations in retirement planning — converting a savings balance into predictable monthly income that does not run out before the end of the chosen period.
How Annuity Payouts Are Calculated
A fixed annuity distributes both principal and interest earnings over a set number of periods. The payment formula divides the present value by the present value annuity factor, which accounts for the interest rate and number of payments. Higher interest rates produce larger payments because more interest earnings supplement principal. Shorter durations also produce larger payments because the same balance is spread over fewer periods. The key insight is that each payment is partially interest (on the remaining balance) and partially principal return.
Payment = PV × [r / (1 − (1 + r)^−n)] Where: PV = present value (lump sum) r = period interest rate (annual rate / 12 for monthly) n = total number of payments Example: $200,000 at 5% annual rate for 20 years (monthly): r = 0.05/12 = 0.004167 n = 240 payments Payment = $200,000 × [0.004167 / (1 − (1.004167)^−240)] ≈ $1,319/month
Fixed vs Variable Annuities
Fixed annuities pay the same amount every period regardless of market conditions, providing predictable income that is easy to budget around. Variable annuities tie payouts to investment performance, so income can rise in good markets but fall in bad ones. Indexed annuities offer partial market participation with a floor to prevent losses. This calculator models the fixed type, which is most appropriate for people who need certainty about their monthly income and cannot afford to absorb downside risk.

Annuity Payout vs Systematic Withdrawal
An annuity payout is mathematically similar to a systematic withdrawal from an investment account, but with important differences. A true annuity from an insurance company guarantees payments for life (with a lifetime option), meaning the risk of outliving your money is transferred to the insurer. A self-managed systematic withdrawal leaves longevity risk with the investor: if you live longer than expected or markets underperform, the money may run out. Most financial planners recommend a combination: annuitize a portion of retirement savings for guaranteed income covering basic needs, and keep the rest invested for growth and flexibility.
Frequently Asked Questions
What is an annuity payout?⌄
An annuity payout is a regular cash payment drawn from a lump sum over time. Each payment is a combination of a return of principal and interest earned on the remaining balance. Unlike a simple savings withdrawal where you just draw down the principal, an annuity payout is calculated to distribute both components in equal installments over the entire payout period, so the balance reaches exactly zero at the end of the term.
How long can an annuity last?⌄
Fixed-period annuities can be structured for any duration from one year to thirty or more years. Lifetime annuities continue payments until death and are issued by insurance companies, not calculated from a simple formula. For the fixed-period calculator, longer durations produce smaller individual payments but ensure the money lasts longer. Many retirees choose 20-30 year periods to cover their expected lifespan while still receiving meaningful monthly income.
Does a higher interest rate increase payouts?⌄
Yes, significantly. At 4% interest, $200,000 over 20 years pays about $1,212 per month. At 6% interest, the same balance over 20 years pays about $1,433 per month — nearly $220 more per month, or $52,000 more total. This is why rising interest rate environments generally produce better annuity payouts for new contracts, and why shopping around for rates matters when purchasing an insurance annuity.
What happens to remaining funds if I die before the annuity ends?⌄
For insurance annuities, the answer depends on the contract type. A life-only annuity stops payments at death with no residual value. A period-certain annuity guarantees payments for a specified period regardless of survival; if you die early, a beneficiary receives the remaining payments. A cash-refund annuity pays a beneficiary the difference between what was paid in and what was paid out. For self-managed systematic withdrawals, the remaining balance passes to your estate.
How is an annuity payout different from a pension?⌄
A pension is a defined benefit paid by an employer, funded by the company and often government-backed for certain plans. An annuity is a financial product you purchase (or calculate yourself) where a lump sum is converted to periodic payments. Functionally they pay out similarly, but pensions typically include cost-of-living adjustments and survivor benefits, while annuities vary by contract terms. Both solve the same fundamental problem: converting accumulated wealth into a reliable income stream.
