How to Use This Calculator

  1. Enter your initial investment rate (the rate at which your initial investment earns money)
  2. Specify the time period for which you want to calculate the reinvestment (in years)
  3. Enter the growth rate (how much your investment grows each year)
  4. Click the "Calculate" button to see the results

Understanding the Results

The calculator shows three key results:

  • Final Investment Value: The total value of your investment after the specified time period, including reinvested earnings
  • Total Interest Earned: The total amount of interest earned during the investment period
  • Reinvestment Rate: The rate at which your earnings are being reinvested (calculated as the growth rate)

Example

Suppose you have an initial investment of $1,000 at a 5% rate, and you want to calculate its value over 10 years with a 3% growth rate:

Initial Rate: 5%

Time Period: 10 years

Growth Rate: 3%

Result: Your investment would grow to approximately $1,744.54, with $744.54 in total interest earned, giving you a reinvestment rate of 3%.
