CAGR Calculator
Compute the compound annual growth rate that turns a starting capital into an ending capital over a period.
Quick answer: The compound annual growth rate is the single yearly rate that, compounded each year, grows the starting capital into the ending capital over the given number of years. It smooths away the bumps of individual years into one representative rate. The tool raises the ratio of ending to starting capital to the power of one over the years and subtracts one.
How to use it
Enter the capital you started with, the capital you finished with, and the number of years between them. The output is the compound annual growth rate as a percentage, plus the total growth over the whole period. CAGR assumes smooth compounding and says nothing about the volatility or drawdowns along the way.
Formula
CAGR = ( Ending รท Starting ) ^ ( 1 รท Years ) โ 1
Multiply by 100 to express as a percentage. Years may be fractional.
