Future value calculator
Estimate the future value of a single deposit with reinvested interest.
Formula
Future value = principal × (1 + rate/(100 × periods))^(periods × years)
Future value ≈ (1,000)×(1+(5)÷100÷(12))^((12)×(5)) · Total interest ≈ (1,283.358679)-(1,000)
How to use
- Enter the starting amount and nominal annual rate.
- Set years and compounding periods per year.
- Read future value and total interest.
Examples
- 1,000 at 10%, compounded yearly for 2 years, becomes 1,210.
- 1,000 at 12%, compounded twice yearly for 1 year, becomes 1,123.60.
