CAGR (Compound Annual Growth Rate) Calculator
Calculates the average annual growth rate of an investment over a specified number of years.
Calculates the average annual growth rate of an investment over a specified number of years. Enter your Beginning Value, Ending Value, Number of Years to get an instant compound annual growth rate (cagr). Formula: (pow(ending_value / beginning_value, 1 / number_of_years) - 1) * 100.

How It Works
How It Works
This calculator measures the average yearly growth of an investment over a specific period of time. It shows how fast your money grew each year, assuming the growth happened at a steady rate.
It uses your beginning value, ending value, and number of years in a mathematical formula to calculate a single annual percentage rate. This rate represents the consistent yearly growth that would take your starting amount to your final amount.
- Divides the ending value by the beginning value to find total growth
- Takes the root based on the number of years to find the annual rate
- Subtracts 1 to convert growth into a rate
- Multiplies by 100 to display the result as a percentage
Understanding the Results
The result shows the average annual growth rate of your investment over the selected time period. It smooths out year‑to‑year changes and presents a steady growth rate.
For example, if the result is 8%, it means your investment grew at an average rate of 8% per year during the time period you entered.
- Higher percentages mean faster average growth
- A negative result means the investment decreased in value
- The result assumes steady yearly growth
- Useful for comparing different investments over time
Frequently Asked Questions
What does the CAGR calculator measure?
The CAGR calculator measures the average annual growth rate of an investment over a specific period of time. It shows the constant yearly rate at which an investment would have grown from its beginning value to its ending value. This helps smooth out fluctuations and provides a clear long-term performance indicator.
When should I use a CAGR calculator?
You should use a CAGR calculator when you want to evaluate the performance of an investment over multiple years. It is especially useful for comparing different investments with varying time horizons. CAGR provides a standardized annual growth rate for easier comparison.
What inputs are required to calculate CAGR?
You need three numeric inputs: the Beginning Value (initial investment), the Ending Value (final value), and the Number of Years the investment was held. All values must be positive numbers. The calculator then applies the mathematical formula to compute the annual growth rate.
How is CAGR different from average annual return?
CAGR assumes the investment grew at a steady rate each year, even if actual returns fluctuated. In contrast, a simple average annual return does not account for compounding. CAGR provides a more accurate representation of long-term investment growth.
Can CAGR be negative?
Yes, CAGR can be negative if the Ending Value is less than the Beginning Value. This indicates that the investment decreased in value over the specified time period. A negative CAGR reflects an average annual loss.
What is an example of how CAGR works?
If you invest $1,000 and it grows to $2,000 over 10 years, the calculator determines the consistent annual growth rate required to double the investment in that time. Using the formula, the result would be approximately 7.18% per year. This means the investment effectively grew at an average rate of 7.18% annually.
