- Invested $15,000, returned $22,000 over 4 years → ROI 46.67% ($7,000 profit), annualized ≈ 10.05%
Formula
ROI = (returned − investment) / investment × 100%. Annualized ROI = ((returned / investment)1/years − 1) × 100%. Always annualize when comparing investments held for different lengths of time.
