Annuity Payout Calculator Online
Find the regular payout a lump sum can provide over a set period, right in your browser. Estimates only, not financial advice.
The Annuity Payout Calculator runs entirely in your browser. The principal, rate and term you enter stay on your device and are never uploaded to ArrayKit. Results are estimates only, not financial advice.
Annuity Payout Calculator turns a starting lump sum into the level payment it can support over a chosen number of years at a given rate. Enter the principal, an annual rate, the payout period, and how often you want to be paid — monthly, quarterly or annually — and it solves the standard annuitization formula for the payout amount, then totals what you would receive and how much of that total is interest. It is handy for sizing an income annuity quote, comparing a structured settlement offer, planning a retirement drawdown, or checking how long a lump sum could last at a target payment. These are estimates only, not financial advice — real annuity contracts add fees, taxes and provider-specific crediting rates, so confirm the exact figures with your provider. Everything runs locally in your browser; your numbers are never uploaded.

Common errors & troubleshooting
The Annuity Payout Calculator shows an error instead of a payout. — Make sure the principal and payout period are both greater than 0 and the rate is 0 or more — a blank or negative field triggers the error banner.
The rate was entered as 0.04 instead of 4. — Enter the annual rate as a percentage number, e.g. 4 for 4%, not the decimal fraction 0.04 — the decimal form would understate the payout by roughly 100x.
The payout looks lower than a quoted annuity offer. — This calculator assumes a level, fixed-rate payout with no fees or mortality credits — an insurer's annuity pricing can differ because it pools longevity risk across many policyholders and may include riders or fees.
Switching payout frequency changes the total payout amount. — That's expected: more frequent payouts compound the remaining balance more often within the year, so monthly, quarterly and annual payouts on the same principal, rate and term produce slightly different totals.
Frequently asked questions
What does the Annuity Payout Calculator solve for?
Given a starting lump sum, an annual rate, a payout period and a payment frequency, it solves for the level payout per period that fully draws down the principal — plus interest earned — by the end of the term.
What formula does the Annuity Payout Calculator use?
It uses the standard annuitization formula PMT = P × i / (1 − (1 + i)⁻ⁿ), where P is the principal, i is the periodic rate and n is the total number of payments — the same math behind a loan payment, applied in reverse to spend down a balance instead of paying one off.
How is the Annuity Payout Calculator different from a retirement or pension calculator?
The Annuity Payout Calculator focuses on one question — what regular payment can a known lump sum support at a given rate and term — rather than projecting savings growth or modeling a full retirement plan.
Can the Annuity Payout Calculator handle a 0% rate?
Yes. At a 0% annual rate the payout is simply the principal divided evenly across the number of payments, since there is no interest to add.
Is the Annuity Payout Calculator's result financial advice?
No. The Annuity Payout Calculator produces estimates only, not financial advice. Real annuity contracts add fees, taxes and provider-specific terms — confirm the exact payout with your annuity provider before deciding.
Does the Annuity Payout Calculator send my numbers anywhere?
No. The Annuity Payout Calculator runs entirely in your browser. The principal, rate and term you enter stay on your device and are never uploaded to ArrayKit.
