How to Use This Compound Interest Calculator
Enter your initial investment, monthly contribution, expected annual interest rate, and investment period.
The calculator estimates how your money could grow when interest is compounded monthly and contributions are added at the end of each month.
It also separates the money you contributed from the interest earned, helping you understand the benefits of compounding.
For example, an initial investment of $10,000, monthly contributions of $200, and a 6% annual rate over 20 years could grow to approximately $114,000.
Results assume a constant annual interest rate with monthly compounding. Actual investment returns vary. Taxes, fees, and inflation are not included.
