Detailed Explanations

Definition and Formula

ROI is a performance measure used to evaluate the efficiency or profitability of an investment. The basic formula is:

$$ \text{ROI} = \frac{\text{Net Profit}}{\text{Investment Cost}} \times 100 \% $$

Where:

• Net Profit: The gain from the investment minus the cost of the investment.
• Investment Cost: The total cost spent on the investment.

Importance and Applicability

ROI is a crucial metric for:

Examples

• Financial Example: An investor buys stocks worth $1,000. After a year, the stocks are worth $1,200. The ROI is \(\frac{200}{1000} \times 100 % = 20% \).
• Marketing Example: A company spends $5,000 on an ad campaign, generating $7,500 in sales. The ROI is \(\frac{2500}{5000} \times 100 % = 50% \).
