How it works
- Enter your goal, starting balance, target date, and estimated annual interest rate.
- The calculator accounts for monthly compounding and divides the remaining target across your deposits.
- Use the monthly figure as a starting plan and adjust it as your savings or timeline changes.
The method
It solves the future-value formula for a series of equal monthly deposits, after allowing the existing balance to compound.
