Savings Calculator
Growth of savings and the monthly amount to hit a goal. Change the numbers and the result updates instantly.
How it works
Enter what you have saved, what you add each month, the interest rate and the number of years. The calculator shows the future balance and, separately, the monthly amount you would need to save to reach a goal. Interest is assumed to compound monthly.
Example
Example: $2,000 plus $300 a month at 4% for 10 years grows to about $47,100. To reach $50,000 in that time you would need to save about $320 a month.
Tips
- Change one input at a time to see what moves the result most.
- Use realistic rates. Check current averages before you decide.
- Results are estimates and do not replace advice from a licensed professional.
