How to read the result
CMGR is the steady monthly rate that would take you from the first number to the last. It smooths over what happened in between, so two very different years can share one CMGR.
It works for anything that compounds: revenue, users, organic traffic. For traffic, compare the same month a year apart to keep seasonality out of it.
The formula
RevenueCMGR = (ending value ÷ starting value) ^ (1 ÷ months) − 1.
Frequently asked questions
