How Compound Interest Builds Wealth

Compound interest is the interest you earn on both your original money and the accumulated interest. Often called "interest on interest," it can significantly accelerate your savings growth over time. Our calculator helps you visualize this powerful financial concept.

How to Use the Calculator:

  • 1. Initial Investment: Enter the starting amount of money you have to invest.
  • 2. Monthly Contribution: Enter the amount you plan to add to your investment each month.
  • 3. Length of Time: Specify the number of years you plan to let your investment grow.
  • 4. Estimated Interest Rate: Input the annual interest rate you expect to earn. This is an estimate and can vary.

Understanding the Results

As you adjust the parameters, the **Future Value** and the **Projected Growth** chart will update instantly. The chart provides a clear visual of how your investment is projected to grow year over year, demonstrating the accelerating power of compounding.
