CAGR, or Compound Annual Growth Rate, is a financial metric that represents the mean annual growth rate of an investment over a specified time period longer than one year. It describes the rate at which an investment would have grown if it had grown at a steady rate, which rarely happens in reality. CAGR smooths the returns and provides a clearer picture of investment performance.
CAGR = (Ending Value / Beginning Value)(1 / Number of Years) - 1
Let's say you invested $10,000 in a stock, and after 5 years, your investment is worth $16,105. To calculate the CAGR:
Using the CAGR formula: CAGR = ($16,105 / $10,000)(1/5) - 1 = 0.10 or 10%
This means your investment grew at an average annual rate of 10% over the 5-year period.
The mathematical formula for CAGR is straightforward but powerful for investment analysis:
CAGR = (End Value / Start Value)(1 / Years) - 1
Let's break down each component of this formula:
Suppose you purchased a property for $200,000 and sold it 7 years later for $350,000. Let's calculate the CAGR manually:
CAGR = ($350,000 / $200,000)(1/7) - 1
CAGR = (1.75)(0.142857) - 1
CAGR = 1.083 - 1 = 0.083 or 8.3%
This means your property appreciated at an average annual rate of 8.3% over the 7-year period.
Excel provides several methods to calculate CAGR, each with its own advantages. Here are the most common approaches:
The POWER function is the most direct way to calculate CAGR in Excel, as it directly implements the CAGR formula:
Example: If your starting value is in cell B1, ending value in B2, and years in B3, the formula would be:
Remember to format the result as a percentage to make it easier to read.
The RATE function is another Excel function that can calculate CAGR, especially useful when dealing with multiple periods:
Example: With the same cell references as above:
Note that the starting value needs to be negative in the RATE function to represent an outflow of cash (investment).
You can also calculate CAGR using basic arithmetic operations in Excel:
Example: With the same cell references:
This method is essentially the same as using the POWER function but may be more intuitive for some users.
For more complex scenarios, you might need to perform advanced CAGR calculations. Here are some techniques:
If your time period isn't in whole years, you can adjust the CAGR formula to account for the exact number of days:
This formula calculates the annualized growth rate based on the exact number of days between the start and end dates.
To calculate CAGR across multiple periods with different values, you can use the GEOMEAN function:
This approach is useful when you have year-over-year growth rates and want to calculate the overall CAGR.
Rolling CAGR calculates the CAGR for overlapping periods, which can help identify trends in performance:
This formula calculates the CAGR for the most recent N-year period, which can be dragged across a row to create a rolling CAGR series.
The CAGR Calculator Excel tool has numerous practical applications across various domains:
CAGR is widely used in investment analysis to compare the performance of different assets over time. By using a CAGR Calculator Excel tool, investors can:
Businesses use CAGR to measure growth across various metrics:
CAGR can be used in financial planning to:
While CAGR is a useful metric, it has several limitations that users should be aware of:
CAGR smooths out the volatility of returns, which can be misleading. An investment with high volatility might have the same CAGR as one with steady growth, but the risk profiles are different.
CAGR is a backward-looking metric and doesn't guarantee future performance. Past growth rates may not continue in the future.
CAGR doesn't account for intermediate cash flows. For investments with regular contributions or withdrawals, other metrics like IRR (Internal Rate of Return) may be more appropriate.
CAGR measures growth between two points in time and ignores what happens in between. Two investments could have the same CAGR but very different growth paths.

The most direct CAGR formula in Excel uses the POWER function: =POWER(End_Value/Start_Value, 1/Years) - 1. Alternatively, you can use the RATE function: =RATE(Years, 0, -Start_Value, End_Value). Both will give you the same result when formatted as a percentage.
The average growth rate simply divides the total growth by the number of years, ignoring compounding effects. CAGR accounts for compounding by calculating the consistent rate that would take you from the beginning value to the ending value over the specified period. CAGR is generally considered more accurate for measuring investment performance over multiple periods.
For monthly data, use the formula: =(End_Value/Start_Value)^(12/Months) - 1. For quarterly data: =(End_Value/Start_Value)^(4/Quarters) - 1. This annualizes the growth rate regardless of the time period used in the calculation.
Yes, CAGR is an excellent metric for comparing companies, especially when they have been in business for different time periods. By calculating the CAGR of revenue, profit, or other key metrics for each company over the same time frame, you can make meaningful comparisons of their growth performance.
A "good" CAGR depends on the asset class, risk level, and market conditions. Historically, the S&P 500 has delivered a CAGR of approximately 10% before inflation. Higher-risk investments might aim for 15-20% CAGR, while more conservative investments might target 4-7%. It's important to compare CAGR to relevant benchmarks and consider the risk involved.
CAGR assumes a single initial investment and a single final value, with no intermediate cash flows. IRR (Internal Rate of Return) accounts for multiple cash flows at different times. For simple scenarios with only beginning and ending values, CAGR and IRR will be the same. For complex scenarios with multiple cash flows, IRR is more appropriate.
Yes, CAGR can be negative if the ending value is less than the beginning value. This indicates an average annual decline in value over the measurement period. For example, if an investment decreases from $10,000 to $8,000 over 3 years, the CAGR would be approximately -7.2%.
