CAGR Calculator
Measure annualized growth between starting and ending values.
About This Tool
CAGR Calculator helps you measure annualized growth between a starting and ending value. It is designed for investment and wealth planning and keeps the calculation simple enough to compare scenarios without confusion.
Use this calculator when you want a quick view of cagr, absolute gain, ending value before making a money decision. The result updates in your browser, so you can test different assumptions without reloading the page.
How to Use This Calculator
- Enter the values that match your real situation, not just ideal numbers.
- Review the main result first, then look at the supporting figures and chart where available.
- Change one input at a time so you can see what actually moves the result.
- Compare at least two scenarios, such as conservative and optimistic assumptions.
How the Calculation Works
The calculator converts total growth over several years into a single annualized growth rate.
The calculator converts growth from starting value to ending value into a smoothed annual growth rate.
Formula Used
CAGR = (Ending Value / Starting Value)^(1 / Years) - 1.
Input Field Explanation
Starting Value
Enter the starting value of the investment or portfolio.
Ending Value
Enter the ending value you want to compare against the starting value.
Years
Enter the number of years for the estimate. A longer period can change the result significantly.
Example Calculation
For example, an investment that doubles over several years will show the steady annual rate needed to reach that result.
If an investment grows from 100,000 to 200,000 over several years, CAGR shows the steady annual rate behind that growth. Replace the sample values with your own numbers before using the estimate for planning.
Benefits of Using This Tool
- Makes multi-year returns easier to compare.
- Useful for portfolio and business growth review.
- Smooths uneven growth into one annual figure.
- It helps you compare long-term scenarios before committing money.
Common Mistakes to Avoid
- Treating CAGR as the return earned every year.
- Ignoring cash flows added during the period.
- Comparing CAGR across different risk levels blindly.
- Do not assume the same return every year just because a calculator uses a steady rate.
- Do not treat the estimate as a guaranteed final outcome.
Things to Consider
- CAGR does not show volatility.
- It works best when start value, end value and period are clear.
- Use XIRR-style methods for irregular cash flows.
- Market-linked investments can move up and down, so use a range of assumptions.
- Confirm important numbers with official documents or a qualified professional when needed.
Frequently Asked Questions (FAQ)

No. Actual yearly returns can be higher or lower than the CAGR.
Is the CAGR Calculator free to use?
Yes. You can use it free on The Market Side Tools without creating an account.
What does the CAGR Calculator calculate?
It calculates cagr, absolute gain, ending value based on the values you enter.
Does this tool save my data?
Values entered into this calculator are processed in your browser for quick estimates.
How accurate is the result?
The math follows the formula, but real-world results can differ because rates, taxes, fees and timing can change.
