Compound Annual Growth Rate Calculator

Compound Annual Growth Rate Calculator

Calculating the Compound Annual Growth Rate (CAGR) is a common financial task that can help you evaluate investments, business performance, and more.

What is CAGR?

CAGR, or Compound Annual Growth Rate, is a crucial financial metric used to determine the annual growth rate of an investment or business asset over a specified period. It provides a more accurate representation of growth when compared to simple annual growth rates. CAGR is particularly useful when analyzing investments with irregular growth patterns.

Understanding the CAGR Calculator

A CAGR calculator simplifies the process of finding the annual growth rate over a given period. It’s a user-friendly tool that takes three key inputs:

  1. Starting Amount: The initial value of your investment or asset.
  2. Ending Amount: The final value of your investment after the specified time.
  3. Number of Years: The time period over which the investment grew.

The calculator then uses a mathematical formula to determine the CAGR and provides you with the result, usually expressed as a percentage.

How the CAGR Formula Works

The CAGR formula is as follows:

CAGR = [(Ending Amount / Starting Amount) ^ (1 / Number of Years)] – 1

  • Ending Amount: The final value of the investment or asset.
  • Starting Amount: The initial value of the investment or asset.
  • Number of Years: The duration over which the investment grew.

Step-by-Step Calculation Using the Tool

Here’s a detailed breakdown of how to use a CAGR calculator tool:

  1. Input Data: Enter the “Starting Amount,” “Ending Amount,” and the “Number of Years” into the respective fields.
  2. Calculation: Click on the “Calculate CAGR” button. The tool performs the following calculations:
    • It divides the “Ending Amount” by the “Starting Amount.”
    • It raises this division result to the power of 1 divided by the “Number of Years.”
    • It subtracts 1 from this value.
  3. Displaying the Result: The calculator displays the CAGR as a percentage. It provides you with a clear understanding of the annual growth rate for your investment.

Practical Use Cases

CAGR is a valuable metric for assessing investments, whether you’re a financial analyst, a business owner, or an investor. Some practical use cases include:

  • Investment Analysis: Use CAGR to evaluate the growth of stocks, bonds, or any investment over time.
  • Business Growth: Assess your company’s growth rate over multiple years, making it easier to set performance goals.
  • Comparing Investments: Compare different investments to determine which one offers the best return.


In the world of finance and investment, the Compound Annual Growth Rate (CAGR) calculator is an indispensable tool. It simplifies complex calculations and provides a clear picture of annual growth rates. Understanding how to use this tool is essential for anyone dealing with investments, financial analysis, or business evaluation. Make sure to use it wisely to make informed decisions and drive your financial success.
