Return on Investment (ROI)

ROI measures the profitability of an investment as a percentage of the initial cost. Annualized ROI accounts for the time period to enable fair comparisons.
ROI = (Final Value - Initial Investment) ÷ Initial Investment × 100% Annualized ROI = [(Final ÷ Initial)^(1/Years) - 1] × 100%
