About the CAGR Calculator

The CAGR Calculator calculates compound annual growth rate between a starting and ending value over any number of years. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Reporting revenue growth over several years as one number.

The maths behind it

This tool uses CAGR = ((ending ÷ beginning)^(1 ÷ years) − 1) × 100. Every intermediate value is shown on screen, so the result can be checked by hand.

Frequently asked questions

Is the CAGR Calculator free?
It is free, with no account, no trial and no daily cap. Every calculators tool on inputtesthub.com works the same way: open the page and use it.
Can you see what I put into this utility?
No. The CAGR Calculator runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
What is the equation behind the CAGR Calculator?
It uses CAGR = ((ending ÷ beginning)^(1 ÷ years) − 1) × 100. The full working is printed under the result, so you can follow every step rather than trusting a black box.
What problem does the CAGR Calculator solve?
The most common reasons people reach for it: comparing the growth of two investments fairly. Reporting revenue growth over several years as one number. Sanity-checking a fund's advertised returns. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Can I rely on this for exact work?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
