What is an Annuity?

An annuity is a series of payments made at equal intervals. Examples include structured settlements, lottery payouts, and retirement funds.

Ordinary Annuity vs. Annuity Due

This calculator uses the Ordinary Annuity formula, which assumes payments are made at the end of each period (monthly).

Present Value formula

PV = PMT × [1 - (1 + r)^-n] / r

Future Value formula

FV = PMT × [(1 + r)^n - 1] / r
