CAGR Calculator
Compound annual growth rate between a beginning and ending value.
Formula: CAGR = (End / Begin)^(1/years) − 1
About the CAGR Calculator
The CAGR Calculator gives you an instant answer from just a few inputs — beginning value, ending value, years. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install. Under the hood it applies the formula CAGR = (End / Begin)^(1/years) − 1.
Worth Knowing
CAGR smooths a bumpy multi-year growth path into a single steady annual rate that would have produced the same ending value — it's the geometric average, not the arithmetic one, and the two can differ substantially when returns are volatile. That smoothing is exactly why CAGR is useful for comparing investments over different time periods, but also why it can mask large swings — a fund with a smooth 8% CAGR and one that crashed 40% then rallied 80% can post identical CAGRs despite a very different ride.
How to Use
- Enter Beginning value into the first field of the CAGR Calculator.
