CAGR is the constant rate that would take a starting value to an ending value over N years if compounded annually. It smooths out bumps in returns.

CAGR = (ending value / beginning value)^(1/years) − 1

$10,000 grows to $15,000 over 5 years: (15000/10000)^(0.2)-1 = (1.5)^0.2 - 1 ≈ 0.08447, so 8.45% CAGR.

Assumes growth was compounded over the period and there were no contributions or withdrawals. Past performance doesn't guarantee future results.

A high CAGR over a short period can be misleading; compare over similar time horizons.
