ROI = [ (Final Value - Initial Investment) / Initial Investment ] × 100Explanation of Variables
| Symbol | Variable Name | Description & Role in Calculation |
|---|---|---|

Worked Calculation Examples
Stock Market Gain
Scenario: Purchased shares for $5,000 and sold them 2 years later for $7,500.
Business Venture Loss
Scenario: Invested $20,000 into a business project, terminating at $15,000 after 1 year.
Interpretation of Results
Return on Investment (ROI) expresses net profitability as a percentage of initial cost. While simple ROI indicates total percentage gain, annualized ROI (CAGR) normalizes performance across multi-year holding periods.
Total ROI (%)
The aggregate percentage return earned over the entire lifespan of the investment.
Key Context: Positive percentages indicate net profits; negative values indicate capital loss.
Annualized ROI (%)
The compound yearly rate of return required to generate the total gain over the given years.
Key Context: Allows direct apple-to-apples comparison against annual benchmark indices like the S&P 500.
