Time Value of Money Formulas

Future Value: FV = PV(1 + r)^n

Present Value: PV = FV / (1 + r)^n

FV of Annuity: PMT × [((1 + r)^n - 1) / r]

PV of Annuity: PMT × [(1 - (1 + r)^-n) / r]

Where: r = rate per period, n = total periods

About This Calculator

Present Value / Future Value Calculator is designed to reduce manual errors and give repeatable outputs when you need quick, reliable answers.

Translate money across time horizons by converting present value to future value (and reverse) under chosen discount rates.

If your workflow expands, pair this calculator with Compound Interest Calculator and NPV-IRR Calculator to cross-check assumptions and build a stronger analysis chain.

Formula

Future Value = Present Value * (1 + r)^n; Present Value = Future Value / (1 + r)^n
