How to use the CAGR Calculator
- Enter the starting value.
- Enter the ending value.
- Set the number of years between them.
- View the CAGR percentage and year-by-year projection.
Formula and method
CAGR = (End / Start)1/years − 1
Frequently asked questions
How is CAGR different from average return?
Simple average adds yearly returns and divides by years. CAGR accounts for compounding — it is the rate that would produce the actual end value from the start value.
Can CAGR be negative?
Yes. If the end value is lower than the start value, CAGR will be negative, reflecting annualised decline.
Is CAGR suitable for volatile investments?
CAGR gives the smoothed rate. It hides volatility. For risk assessment, look at standard deviation or maximum drawdown alongside CAGR.
