Future Value Calculator
Enter a starting balance, a monthly deposit, an annual return and a time period. Starting with $10,000 and adding $200 a month at 6 percent for 15 years grows to $82,704.68.
How the future value calculator works
Future value is what money you have now, plus regular deposits, will be worth later at a given interest rate. This calculator compounds monthly and assumes you deposit at the end of each month.
The formulas
Example: Start with $10,000, add $200 a month, earn 6 percent a year for 15 years. Total deposits are $46,000.00, the future value is $82,704.68 and interest earned is $36,704.68.
Notes and limits
- The rate is assumed constant. Real returns change from year to year.
- Taxes, fees and inflation are not included.
- For the same math in Excel use =FV(rate/12, years*12, -deposit, -balance).
Figures are estimates for planning and are not financial advice. Check your own agreement or statement for exact terms.
