About CAGR Calculator
The CAGR Calculator works out the compound annual growth rate between a beginning value and an ending value — the single constant yearly rate that would have taken you from one to the other. It is the standard way to compare investments, revenue lines or user counts whose year-to-year paths look nothing alike.
The formula is CAGR = (ending ÷ beginning)^(1 ÷ years) − 1. Because it smooths out every peak and dip in between, a CAGR of 12% does not mean any single year returned 12%; it means the compounded result matches what a steady 12% would have produced.
The tool also runs in reverse. Solve for the final value from a rate and a number of years, or solve for how many years a given rate needs to reach a target — useful for goal setting and for sanity-checking growth claims. Alongside the rate it reports total growth, the growth multiple and the absolute gain.
