Annuity calculator

Solve any one annuity value, payment, present or future value, rate, or term, from the other four, with a full per period balance schedule.

Fill in the four known values to solve the fifth.

The closed forms are the same ones Excel and Google Sheets use for PMT, PV, FV and NPER, so answers line up with a spreadsheet. When you solve the interest rate there is no closed form, so the tool narrows a fixed search range by bisection until the four given values balance; the same applies to a solved term when the answer is not a whole number of payments. What it does not do: fees or charges, tax, index-linked or stepped payments, overpayments, payment holidays, or day-count date arithmetic. Interest compounds once per period, and the annual rate is nominal, not effective.
