What is the Annuity Calculator?
Estimate a mathematical level payout from a fixed starting balance. This tool is a present-value model, not an insurance-company annuity quote.
The calculation amortizes the entered balance into level payments over a fixed number of periods at a constant interest rate.
Formula and calculation method
PMT = PV × r ÷ (1 − (1 + r)^−n), adjusted for beginning-of-period payments.
The result uses only the values entered on this page. It does not fetch account balances, market prices, tax returns or provider quotes.
Important limitations
Financial projections simplify real life. Returns can vary, laws and limits can change, inflation is uncertain, and taxes or fees may apply. Review the result as a scenario—not a promise.
Financial scope: Educational estimates only; not financial, investment, tax, legal or insurance advice.
