How the Annuity Payout Calculator Works
An annuity payout converts a lump sum into a stream of fixed periodic payments over a set term, with each payment including both a return of principal and interest earned.
This annuity payout calculator computes:
- Payment Amount — your fixed periodic payment
- Total Payments Received — the sum of all payments over the term
- Total Interest Earned — how much of your payout is interest, not principal
- Number of Payments — total number of payments you’ll receive
Annuity Payout Formula
Payment = P × r ÷ [1 − (1 + r)^(−n)]
Where: - P = Principal (premium paid) - r = Periodic interest rate (annual rate ÷ payments per year) - n = Total number of payments

Frequently Asked Questions
What is an annuity payout?
An annuity payout is the fixed periodic payment an annuity holder receives in exchange for a lump-sum premium, calculated so that the principal plus interest is paid out evenly over the chosen term.
How is the annuity payment calculated?
The payment is calculated using the annuity payment formula, which amortizes the principal plus interest evenly across all payments over the payout term at the given interest rate.
What’s the difference between a period-certain and lifetime annuity?
A period-certain annuity pays out over a fixed number of years regardless of whether the holder is alive, while a lifetime annuity pays for as long as the holder lives, which involves actuarial calculations based on life expectancy rather than a fixed term.
Are annuity payments taxed?
For non-qualified annuities purchased with after-tax dollars, a portion of each payment (the return of principal) is typically tax-free, while the interest/earnings portion is taxable as ordinary income. Qualified annuities (funded with pre-tax dollars) are generally fully taxable.
