ROI vs. CAGR
ROI is the total percentage gain regardless of time; CAGR spreads it into an equivalent yearly rate. A 40% ROI is excellent over 3 years (11.9% CAGR) and mediocre over 10 (3.4%). Always annualize before comparing investments held for different periods.
Count every cost
Honest ROI includes all cash out: fees, taxes, maintenance, and your time where relevant. Real estate 'doubled my money' claims often omit a decade of property tax, insurance, and repairs that cut the true CAGR by several points.
