The Compound Annual Growth Rate (CAGR) is a valuable financial metric used to measure the average annual growth rate of an investment over a specified period, assuming the returns are reinvested. Calculating CAGR in Excel is simple and helps investors and analysts assess the growth of investments or businesses effectively. This guide will walk you through the process of calculating CAGR in Excel.
What is CAGR?
CAGR provides a single annual growth rate that represents the steady progress of an investment over a given time. Unlike irregular year-over-year growth rates, CAGR smooths fluctuations, offering a clearer picture of long-term performance.
Steps to Calculate CAGR in Excel
1. Input Your Data
Create a table in Excel with the following columns:
- Year: List the years (e.g., 2020, 2021, 2022).
- Value: Enter the corresponding values of the investment for each year.
For example:
| Year | Value |
|---|---|
| 2020 | 10,000 |
| 2023 | 15,000 |
2. Apply the CAGR Formula
To calculate CAGR, follow these steps:
- Identify the Beginning and Ending Values
- Use the first and last values in your data:
- Beginning Value: 10,000
- Ending Value: 15,000
- Use the first and last values in your data:
- Determine the Time Period (n)
- Subtract the start year from the end year to get the duration in years:
2023−2020=32023 – 2020 = 3.
- Subtract the start year from the end year to get the duration in years:
- Enter the Formula in Excel
In an empty cell, type:=(Ending Value / Beginning Value)^(1/Number of Years) - 1Using our example:
=(15000 / 10000)^(1/3) - 1 - Format the Result as a Percentage
- Select the cell with the formula.
- Go to the “Home” tab and click on “Percentage” to format the result as a percentage.
3. Use the POWER Function
Alternatively, you can use Excel’s POWER function to calculate CAGR:
=POWER(Ending Value / Beginning Value, 1/Number of Years) - 1
For the example:
=POWER(15000 / 10000, 1/3) - 1
Example Output
Using the above data, the CAGR is:
14.47%
Why Use CAGR?
CAGR simplifies complex growth rates into a single, understandable metric. It’s invaluable for:
- Comparing investment performances
- Assessing business growth
- Forecasting future trends
