ROI vs. annualized return
ROI = (Final value − Cost) ÷ Cost × 100. It tells you the total percentage gain but ignores time: a 50% ROI is spectacular over one year and mediocre over fifteen. Annualized return (CAGR) fixes this by expressing the growth as a constant yearly rate: CAGR = (Final/Initial)^(1/years) − 1.
When comparing investments with different durations, always compare CAGR, not raw ROI. Include all costs — fees, taxes, maintenance — in the invested amount for an honest figure.
Frequently Asked Questions
▸What is a good ROI?
Context matters: long-run stock market CAGR is about 7–10%; real estate and small businesses vary widely. Compare against alternatives of similar risk, not a universal number.
▸What is the difference between ROI and CAGR?
ROI is the total percentage return over the whole period. CAGR is the equivalent constant annual growth rate, which makes investments of different durations comparable.
