How Future Value Is Calculated

The future value calculation combines the growth of an initial lump sum with the accumulated value of periodic payments, both earning compound interest.

The Formula

FV = PV(1 + r)n + PMT × [((1 + r)n - 1) / r]

  • PV = Present Value (initial deposit)
  • PMT = Payment per period
  • r = Interest rate per period (annual rate / payments per year)
  • n = Total number of periods (years × payments per year)

For an annuity due (payments at the beginning of each period), the payment portion is multiplied by (1 + r), giving a slightly higher future value since each payment earns interest for one additional period.
