How is Return on Investment (ROI) calculated and what does it indicate?

• A. ROI equals total revenue divided by initial investment cost.
• B. ROI equals operating income divided by initial investment cost.
• C. ROI is the ratio of net profit to total assets invested.
• D. ROI equals net profit divided by initial investment cost, indicating profitability and efficiency.

Answer: (D)

ROI measures how much profit you earn for every dollar you invest. It’s calculated by dividing net profit by the initial investment cost, giving a percentage that shows both profitability and how efficiently capital is used. Net profit is what remains after subtracting all costs, taxes, and expenses from revenue, so this metric reflects true financial return, not just sales. For example, if you invest $10,000 and your net profit is $2,000, ROI is 2,000 / 10,000 = 20%. This means you earned 20 cents of profit for every dollar invested, indicating the investment’s effectiveness. Using total revenue isn’t the best measure here because it ignores costs and expenses. Using operating income can miss non-operating items and taxes, so it doesn’t fully capture overall profitability. A similar ratio with a denominator like total assets owned is a related idea but isn’t the standard definition when the investment cost is the reference point.
