CAGR Calculator
Compound annual growth rate
For reference only. It assumes a constant annual return; actual returns vary year to year and future returns are not guaranteed.
How to use
Enter a starting value, an ending value and a period to find the constant annual rate that would grow one into the other. You can also work backwards to find how many years a target needs at a given return, or the value after a set number of years, and it shows the doubling time and the rule of 72 estimate.
Q. How is CAGR different from an average return?
A. A simple average adds up yearly returns and divides, while CAGR accounts for compounding and finds the single constant yearly rate that takes the starting value to the ending value. The gap grows the more uneven the returns are.
Q. What is the rule of 72?
A. Dividing 72 by the annual return in percent gives a rough number of years for money to double. The calculator shows both the exact figure and the rule of 72 estimate.
