Model retirement savings, compound interest on a deposit, or the future balance of a recurring investment plan.
Step-by-step instructions
How to fv future value — 3 steps
Divide the annual rate by 12 to get the monthly compounding rate.
Multiply the investment horizon in years by 12 for total months.
Enter the monthly contribution as a negative number — FV treats payments as cash outflows, returning a positive future balance.
Example data
Worked example
| Parameter | Value |
|---|---|

Common mistakes
Errors to watch out for
FV returns a negative number
FV returns a negative result when payments are positive. Negate your payment input (-B3) or wrap the result in ABS() to get a positive future balance.
Rate and periods are mismatched
Use the same time unit for rate and nper. Monthly contributions need a monthly rate (annual/12) and total months (years×12).
