About Future Value Calculator
Formula
FV = PV × (1 + r/n)n·t where r is the annual rate, n the compounding periods per year, and t the time in years.
Compounding effect
Higher compounding frequency raises the effective rate slightly. Going from annual to monthly compounding at 7% turns 7.000% into ~7.229% effective.
For periodic deposits
This calculator handles a single lump sum. For regular monthly contributions, use the Compound Interest Calculator.
