Annuity Payout Calculator
Calculate annuity income for a fixed term or the duration of a chosen payout.
Solve a fixed payout amount or how long a fixed payment can last.
Result
Payouts occur at period end. The final payout drains the remaining balance; a partial final period earns only its fractional-period return and can have a different payout. No tax or insurance fees are modeled.

How to use this calculator
Solve a fixed payout amount or how long a fixed payment can last. Enter amounts in the units shown, select the applicable options, and click Calculate. Use Reset to restore the starting values.
Calculation formula
Payout = principal / annuity present-value factor.
Assumptions and accuracy
Review timing, rates, fees and result notes when comparing scenarios. Future returns and rates are assumptions rather than guaranteed outcomes. Monetary display follows the currency’s precision; intermediate calculations retain additional digits.
Choose what to calculate
How long will my annuity payments last calculator
Estimate how long a fixed annuity payment can last, or solve a payment for a chosen term. The final payment is capped at the remaining balance.

Open this calculationUnderstanding this calculation
Estimate a regular withdrawal from a balance over a term, or solve for duration given a payment. Payment frequency determines how the annual rate is translated into periods.
Worked examples
Monthly withdrawals from a zero-return annuity balance
Illustrative inputs are specified in the steps below; the example link loads the complete settings. Unmentioned settings use the linked defaults.
- A 12,000 balance divided over 12 monthly withdrawals gives 1,000 per month, exhausting the balance after one year.
Payment each period: 1,000 USD.
Try these inputsCommon questions
Will an annuity payout last for life?
A fixed-term balance-depletion calculation is not a life-contingent insurance promise. Actual lifetime products require different assumptions.
Why does a higher withdrawal shorten duration?
More principal is used each period after growth. If withdrawals exceed sustainable growth, the balance eventually runs out.
Scope and assumptions
The model assumes a deterministic return and does not price an insurer's lifetime guarantee or mortality pooling.
