Future Value of Annuity Calculator
Compare future values of equal payments at each period end or beginning with a fixed periodic rate.
Formula
Ordinary FV = PMT×[(1+r)^n−1]/r; due FV = ordinary FV×(1+r); r=periodic%/100
End-of-period payments FV (money) ≈ (100)×((1+(0.01))^(12)-1)÷(0.01) · Beginning-of-period payments FV (money) ≈ (1,268.250301)×(1+(0.01)) · Total payments (money) ≈ (100)×(12)
How to use

- Enter the rate per period and number of periods.
- Compare end-of-period and beginning-of-period values.
Examples
- Two payments of 100 at 10% per period give 210 ordinary or 231 due.
