Future Value of Annuity Calculator

An annuity is a series of equal payments made at regular intervals, such as a regular contribution to a retirement or savings fund. This calculator works out the future value of an annuity: what a stream of equal yearly payments will be worth after a set number of years, given a fixed interest rate. It helps with decisions relating to the time value of money. Enter the regular payment you make each year, the interest rate earned, and the number of years. We assume each payment is made at the end of the year (an ordinary annuity) and a static interest rate, since predicting future rate movements is almost impossible. The future value is the sum of every payment compounded forward to the end of the term, calculated as payment times ((1 + rate) to the power of years, minus 1) divided by the rate.
