CAGR Calculator
Free CAGR calculator: the compound annual growth rate between a beginning and an ending value, the total growth, the years to double and a yearly table.
No currency is shown on purpose: the figures come out in whatever unit you type in.

What it does
CAGR is the steady yearly growth rate that takes a beginning value to an ending value over a number of years: (ending ÷ beginning)^(1 ÷ years) − 1. It is used for revenue, users, investments and prices because it smooths out the ups and downs of single years into one comparable number.
How to use it
- Type the beginning value and the ending value.
- Type the number of years between them; fractions such as 2.5 are fine.
- Read the CAGR, the total growth, the years to double and the value each year at that rate.
The arithmetic runs in your browser. Nothing you type is sent anywhere and nothing is stored, so you can use these with real numbers.
Frequently asked questions
Why not just average the growth of each year?
Because averages of percentages mislead. Going from 100 to 150 (+50%) and then to 144 (−4%) averages +23% a year, but 100 growing 23% a year for two years would reach 151. The CAGR is 20.00%: 100 × 1.2 × 1.2 = 144.
Can the CAGR be negative?
Yes. If the ending value is below the beginning value, the CAGR is the steady yearly rate of decline. A value that halves in 3 years has a CAGR of about −20.6%.
What does the CAGR hide?
The path. Two investments with the same CAGR can have very different ups and downs along the way. It also depends on the start and end dates chosen: starting at a low point or ending at a peak inflates it.
Can I use the CAGR to project the future?
As a rough scenario, yes: the table shows the value each year at that rate. But past growth does not guarantee future growth, and high rates rarely last for long.
