Return on Investment (ROI) is a universal financial metric used to evaluate the efficiency or profitability of an investment asset relative to its cost.
The financial equations are:
\(\text{Net Gain / Loss} = \text{Amount Returned} - \text{Amount Invested}\)
\(\text{Simple ROI (\%)} = \left(\frac{\text{Amount Returned} - \text{Amount Invested}}{\text{Amount Invested}}\right) \times 100\)
\(\text{Annualized ROI (CAGR \%)} = \left[ \left(\frac{\text{Amount Returned}}{\text{Amount Invested}}\right)^{\frac{1}{\text{Years}}} - 1 \right] \times 100\)
Comparing Short-Term vs Multi-Year Investments: Simple ROI works best for short-term trades. When holding assets across multiple years, using Annualized ROI (CAGR) allows direct comparison against market benchmarks like the S&P 500 (~10% CAGR).
