About this tool
This calculator finds the future value of an annuity, a series of equal payments made once a year. It uses the formula future value = payment times ((1 + r) raised to the power of n, minus 1) divided by r, where r is the annual rate and n is the number of years. It assumes each payment is made at the end of the year.
Frequently asked questions
What is an annuity?
An annuity is a stream of equal payments at regular intervals, such as annual contributions to a savings plan or yearly payouts from a retirement product.
What if the interest rate is zero?
Then the future value is simply the annual payment times the number of years, because no interest is earned. The calculator handles that case automatically.
