Calculate the Compound Annual Growth Rate (CAGR) to understand the average yearly growth of an investment over a specific period.
Last updated on: Jun 16, 2026
CAGR, or Compound Annual Growth Rate, is commonly used to evaluate returns from stocks, mutual funds, portfolios, and business revenue over a specified period. An online CAGR calculator simplifies the process and provides quick and accurate results.
CAGR stands for Compound Annual Growth Rate. It represents the average annual growth rate of an investment over a specified period, assuming the profits are reinvested every year.
CAGR provides a standardised annualised growth rate by expressing overall growth over a period as a single annual rate, which can be used for comparison across investments.
It is commonly used to evaluate:
Stock market investments
Mutual fund returns
Business revenue growth
Portfolio performance
Long-term financial projections
For example, if an investment grows from ₹1 Lakh to ₹2 Lakhs over five years, CAGR calculates the average yearly growth rate required to achieve that increase.
Unlike simple return calculations, CAGR considers the compounding effect over time.
A CAGR calculator works by using the starting value, ending value, and investment duration to determine the annual growth rate.
The process generally includes:
Entering the initial investment value
Entering the final investment value
Specifying the investment duration in years
Calculating the annualised growth rate using the CAGR formula
The calculator uses compounding principles to derive a consistent annual growth rate.
Key components involved are:
Beginning Value: Initial investment amount
Ending Value: Final investment value
Time Period: Total duration of the investment
The output is displayed as an annual percentage growth rate.
Using a CAGR calculator online is a simple process.
Follow these steps:
Enter the initial investment amount
Add the final investment value
Enter the investment duration in years
Click on the calculate option
Review the CAGR percentage displayed by the calculator
Most online calculators generate results instantly after receiving the required inputs.
The accuracy of the calculation depends on entering correct investment values and duration.
CAGR is calculated using a mathematical formula based on compounding principles.
The formula is:
CAGR = [(Ending Value ÷ Beginning Value) ^ (1 ÷ Number of Years)] − 1
Where:
Ending Value: It is the final value of the investment
Beginning Value: It is the initial amount invested
Number of Years: It is the total investment period
The result is usually expressed as a percentage.
CAGR provides a smoothed annual growth rate rather than showing year-to-year volatility.
The CAGR formula can be applied manually using the following process:
Divide the ending investment value by the beginning value
Raise the result to the power of 1 divided by the number of years
Subtract 1 from the result
Convert the figure into a percentage
This method helps determine the average annual growth rate over the investment period.
The following table shows a simple CAGR calculation example.
| Investment Detail | Value |
|---|---|
Beginning Investment |
₹1,00,000 |
Ending Investment |
₹1,80,000 |
Investment Period |
5 Years |
Using the formula:
CAGR = [(1,80,000 ÷ 1,00,000) ^ (1 ÷ 5)] − 1
The CAGR result is approximately 12.47%.
This means the investment grew at an average annual compounded rate of 12.47% over five years.
A reverse CAGR calculator works in the opposite direction of a standard CAGR calculator.
Instead of calculating the growth rate, it estimates:
The future investment value based on a target CAGR
The required starting value to achieve a future target amount
The investment duration needed to reach a financial goal
This type of calculator is useful for planning long-term investment targets and estimating required growth assumptions.
A reverse CAGR calculator uses the target CAGR along with investment duration to estimate future or required values.
The process generally includes:
Entering the expected CAGR percentage
Adding the current or target investment value
Specifying the investment duration
Calculating the missing financial variable
It is commonly used for financial planning and investment projections.
A stock CAGR calculator helps measure the average annual return generated by a stock investment over a specific period.
The calculation uses:
Purchase price of the stock
Current or selling price
Holding period
Stock CAGR calculation helps compare the performance of different stocks using a standardised annual growth rate.
For example, if a stock investment grows steadily over several years, CAGR helps show the average yearly growth instead of focusing on short-term volatility.
CAGR and absolute return measure investment performance differently.
| Aspect | CAGR | Absolute Return |
|---|---|---|
Meaning |
Annual compounded growth rate |
Total return over the investment period |
Time Factor |
Considers investment duration |
Does not consider duration |
Compounding Effect |
Included |
Not included |
Use Case |
Long-term investments |
Short-term performance evaluation |
Output |
Annual growth percentage |
Total gain percentage |
CAGR is generally more useful for evaluating long-term investment growth.
CAGR and XIRR differ based on the type of cash flows involved.
| Aspect | CAGR | XIRR |
|---|---|---|
Cash Flows |
Assumes single investment and redemption |
Handles multiple irregular cash flows |
Use Case |
Lump sum investments |
SIPs and staggered investments |
Complexity |
Simpler calculation |
More complex calculation |
Time Consideration |
Overall investment period |
Exact transaction dates |
XIRR is commonly used for investments involving multiple cash flows, while CAGR is commonly used for lump sum investments.
An online CAGR calculator offers several advantages.
Key benefits include:
Simplifies complex calculations
Saves time compared to manual computation
Provides quick annual growth estimates
Helps compare investment performance
Useful for financial planning and projections
Reduces calculation errors
These calculators are widely used for investment analysis and performance evaluation.
CAGR is used across various financial and business applications.
Common use cases include:
Measuring stock investment performance
Evaluating mutual fund growth
Analysing company revenue growth
Comparing portfolio returns
Financial forecasting and planning
Its standardised format makes CAGR useful for long-term growth comparisons.
The following table highlights the advantages and limitations of CAGR.
| Advantages | Limitations |
|---|---|
Smooths investment growth over time |
Ignores interim volatility |
Easy to compare investments |
Assumes constant growth |
Useful for long-term analysis |
Not suitable for irregular cash flows |
Simple interpretation |
Does not reflect investment risk |
Understanding these limitations helps interpret CAGR results more accurately
Certain points should be considered while using a CAGR calculator.
Important considerations include:
Use accurate beginning and ending values
Enter the correct investment duration
Understand that CAGR assumes steady growth
Consider additional metrics for volatile investments
XIRR is commonly used for investments involving multiple cash flows
These factors may influence the interpretation of CAGR calculations.
Reviewer
Yes, CAGR can be negative if the final investment value is lower than the initial investment amount over the specified period.
Annual return shows the return generated in a single year, while CAGR represents the average compounded annual growth rate over multiple years.
CAGR is generally not suitable for SIP investments because SIPs involve multiple cash flows at different dates. XIRR is commonly used instead.
A CAGR calculator requires the beginning investment value, ending investment value, and the investment duration.
An online CAGR calculator is generally accurate when the correct investment values and time period are entered.
Yes, CAGR is widely used to calculate the average annual growth rate of stock investments over a specified period.
One limitation of CAGR is that it assumes constant growth throughout the investment period and does not reflect short-term market volatility.
