Annuity Payment Calculator — Free
Find equal payments either to amortize a present balance or accumulate a future target. The model uses an ordinary annuity paid at period end, rather than quoting an insurance annuity product.

How to use this tool
Choose PV repayment or FV accumulation, then amount, annual rate, years and payments per year. Duration times frequency must be a whole number; the modes answer different questions even with identical inputs.
Results and examples
At zero interest, a target of 1200 over twelve payments requires 100 each time. At a positive rate, repayment incurs interest while earlier savings payments grow, so the two modes diverge.
Limitations
- Beginning-of-period payments, irregular dates and product fees are excluded.
- Mortality credits, insurance riders and inflation-linked payouts are not represented.
