Breakdown
About this calculator
Future value applies compound growth to a single lump sum. Because returns compound, the difference between 5% and 8% over twenty years is far larger than most people expect.
Worked example
calculated with the default values below
Present value 10,000 $ · Annual return 7 % · Number of years 10 years Future value 19,671.51 $ · Total growth 9,671.51 $ · Growth multiple 1.97 x

Formula and variables
FV = PV x (1 + r/100)^t; growth = FV - PV; multiple = FV / PV
- PV
- present value
- r
- annual interest rate %
- t
- years
- FV
- future value
- growth
- total growth
Annual compounding with the rate entered as a percent; the multiple is FV/PV (0 if PV = 0).
Frequently asked questions
How does a higher annual rate change future value?
The tool computes present value × (1 + annual rate)^years. For $10,000 over 20 years, 5% gives about $26,533 and 8% gives about $46,610, roughly 1.76 times as much, not three times. It models a single initial amount without later contributions, fees, taxes or inflation.
