Context-dependent: broad equity indexes have delivered ~7–10% nominal over long periods; a mature company growing revenue 10%+ is healthy; venture-stage startups are judged against 2–3× annual growth early on. A CAGR only means something against the risk taken to get it.

Worldwide — arithmetic, no local rules

CAGR between a start and end value over a period, plus the reverse projection — and why CAGR beats "average return" for judging any investment or revenue history.

The numbers

CAGR: 12.47%
Total growth: +80%
Growth multiple: 1.8×

The operator’s read

Worth knowing

CAGR is geometric, so it already accounts for compounding — unlike the arithmetic "average annual return," which overstates volatile series (+50% then −50% averages to 0% but is really −13.4% CAGR). Compare investments and revenue histories on CAGR, always.

Methodology

CAGR = (end ÷ start)^(1/years) − 1. It is the constant annual rate that would produce the same endpoint — the geometric mean of the yearly returns.
