ROI vs annualized return — which matters more?
Annualized. A 50% ROI over 10 years is only ~4%/year — barely beating inflation. A 20% ROI in 1 year is a great annualized 20%.
What's a good ROI?
Depends on risk. Savings account: 4-5%. Stock market avg: 7-10%. Real estate: 6-12% inc. rent. Business investment: 15%+ (higher risk, higher expected return).
Should I include fees and taxes?
Yes. True ROI = (Final − Cost − Fees − Taxes) / Cost. Ignoring these overstates returns by 10-30%.
