How to Use This Calculator

This calculator helps you visualize the growth of your investments over time through compound interest. Compound interest is when you earn interest on both your initial investment and on the interest you've already earned.

  • Adjust the Initial Investment to set your starting amount
  • Set your Monthly Contribution - the amount you'll add each month
  • Modify the Annual Interest Rate based on your expected returns
  • Change the Investment Period to see how your money grows over different timeframes
  • Select the Compound Frequency to see how different compounding schedules affect growth

The chart and results will update automatically as you adjust the values. Watch how small changes in contribution or interest rate can dramatically affect your long-term results!
