Compound Interest Calculator

Enter your initial investment, monthly contribution, expected annual return, and investment period. The calculator estimates how your money could grow over time through compound interest.

Your results separate the amount you contributed from the investment growth, making it easier to see how time, regular contributions, and compounding can affect the final balance.

Try changing the inputs to compare different scenarios. Small changes in time, contributions, or return can make a substantial difference over longer periods.
