How to use
- Enter the beginning value and the ending value.
- Give the length as a number of years, or enter the start and end dates.
- Read the compound annual growth rate.
- Check the notes on short periods and on what a smoothed rate hides.
What it checks and how it works
CAGR = (ending value / beginning value) ^ (1 / years) - 1, the formula the Corporate Finance Institute gives. When you enter dates, the span is converted to years at 365.25 days per year.
CAGR is a smoothed rate. It ignores the path between the two ends, so a bumpy history and a steady one can share the same CAGR, and it says nothing about volatility. It is undefined for a zero or negative beginning or ending value, because the formula takes a root of the ratio. Over a period shorter than a year it annualises a short stretch and exaggerates any jump, so the tool warns and suggests comparing the plain change instead.

Questions
About this tool
When the values swing from year to year, when the beginning or ending value is zero or negative, or when the period is very short. In those cases show the actual values by year.
An average of yearly growth rates ignores compounding and can overstate what happened. CAGR is the single rate that would take the beginning value to the ending value over the same period.
Yes, for any positive quantity measured at two points, such as sessions, revenue or customers. Use the same definition at both ends.
