Annuity Payout Calculator
Estimate a fixed annuity withdrawal by payout term or calculate how long a fixed payment can last using a starting balance, return rate, and payout frequency.
Annuity Payout Calculator
Use this free annuity payout calculator to estimate how much you can withdraw from a lump sum over time, or how long a fixed payout can last at a chosen return rate. It is designed for retirement-income planning, drawdown analysis, and comparing payout assumptions before you move into deeper retirement modeling. For more context, compare it with the Present Value Calculator, the Future Value Calculator, the Social Security Calculator, or the full Financial Calculators category.
Rough annual return at the selected rate: $30,000.00. Current payout frequency: monthly.
Use fixed length when you know how long the income stream should last. Use fixed payment when you know the withdrawal amount you want and need to estimate how long the annuity may hold up under a constant return assumption.

This payout plan still benefits from investment return, but principal remains the main source of withdrawals. Small changes in the assumed rate can still shift the ending result.

What is an annuity payout calculator?
An annuity payout calculator is a retirement-income planning tool that turns a starting balance into a structured withdrawal estimate. It helps answer two practical questions: how much can I withdraw for a chosen period, and how long will a chosen payment amount last?
That makes it useful for retirement drawdown planning, pension comparisons, and income-bridge analysis before Social Security or other income starts. If you want to connect the result to today's value or future income targets, continue into the Present Value Calculator, the Future Value Calculator, or other Financial Calculators.
How this calculator works
In fixed-length mode, the calculator uses the standard annuity payout formula to solve for the payment that amortizes the balance over the selected number of periods at the assumed return rate. In fixed-payment mode, it simulates each payout period and determines how many periods it takes for the balance to reach zero.
The year-by-year table then groups the simulation into annual snapshots so you can inspect beginning balance, projected return, and ending balance side by side. To compare this with retirement benefits or broader household planning, also review the Social Security Calculator and the Finance Calculator.
Worked example
The default example uses a $500,000 starting balance, a 6% return, and monthly payouts. It is useful for checking both the fixed-length and fixed-payment modes quickly.
Fixed-length example
With a starting balance of $500,000.00, a 6% annual return, and a 10-year payout term, the calculator estimates a withdrawal of about $5,551.03 per month. Total projected withdrawals reach $666,122.80, including about $166,122.80 of projected return.
Fixed-payment example
Keeping the same starting balance and return rate but fixing the payout at $5,500.00 per month produces an estimated payout life of about 10.2 years. This is useful when you are working backward from a target retirement paycheck rather than a target timeline.
Frequently asked questions
An annuity payout calculator estimates how much you can withdraw from a starting balance based on an assumed rate of return, a payout frequency, and either a target payout length or a fixed periodic withdrawal amount.
