A CAGR calculator is a useful tool that simplifies the process of calculating the CAGR of an investment. It takes the initial investment value, the ending value, and the time period into account and gives you with the CAGR percentage.

How CAGR Calculator work with example

  • Step 1: Gather Information
  • Collect the initial value (IV) of your investment.
  • Determine the ending value (EV) of your investment.
  • Identify the number of years (n) over which the investment has grown.

Step 2: Use the CAGR Formula

  • Put the values into the CAGR formula:
  • [CAGR = \left(\frac{EV}{IV}\right)^{\frac{1}{n}} – 1\]

Step 3: Calculate

  • Divide EV by IV.
  • Raise the outcome to the power of (1/n).
  • Subtract 1 from the above result.


  • Initial Investment (IV): $10,000
  • Ending Value (EV): $15,000
  • Time Period (n): 5 years
  • [CAGR = \left(\frac{15,000}{10,000}\right)^{\frac{1}{5}} – 1\]
  • [CAGR = \left(1.5\right)^{0.2} – 1\]
  • CAGR = 0.2281 or 22.81%

In this example, the CAGR is around 22.81%, which shows that the investment grew at an average annual rate of 22.81% over 5 years. This calculation helps investors understand the yearly growth rate of their investments
