Future value of an annuity is the sum total of a series of cash flows and the interest earned on these cash flows at a predetermined rate, over a certain period or years.

The formula for calculating the Future value of annuity at the end of ‘ n ‘ years is

= P * [ [ ( 1 + r ) ^{n } – 1 ] / r ]

Where

P = Annual cash flow ; r = Discount rate ; n = Number of years of annuity ;

In the calculator below insert the values of Annual cash flow, Discount rate and Number of years to arrive at the Future value of Annuity.
