ROI = (Final Value - Initial Investment) ÷ Initial Investment × 100. E.g., invest $10,000, sell for $13,000 → ROI = 30%.
Annualized ROI adjusts the return to a per-year basis, useful for comparing investments held for different durations.
Divide 72 by the annual return rate to estimate years to double. At 8% return, money doubles in ~9 years (72÷8=9).
