Definition
Return on Investment (ROI) is a financial metric used to evaluate the efficiency or profitability of an investment. It measures the amount of return on an investment relative to the investment’s cost. ROI is expressed as a percentage and is calculated by dividing the net profit by the initial cost of the investment, multiplied by 100.
\[ \text{ROI} = \left ( \frac{\text{Net Profit}}{\text{Cost of Investment}} \right ) \times 100 \]
Examples
-
Simple Example: If an investor invests $1,000 in a project and after one year sells the investment for $1,200, the net profit would be $200. Therefore, the ROI is:
\[ \text{ROI} = \left ( \frac{$200}{$1,000} \right ) \times 100 = 20% \]
-
Business Example: A company invests $50,000 in new machinery to increase production. The increased production results in additional revenues of $70,000 and additional costs of $10,000. The net profit from this investment is $70,000 - $10,000 - $50,000 = $10,000. Therefore, the ROI is:
\[ \text{ROI} = \left ( \frac{$10,000}{$50,000} \right ) \times 100 = 20% \]
Frequently Asked Questions (FAQs)
What is a good ROI?
A “good” ROI varies by industry and risk tolerance but generally, a higher ROI indicates a more favorable investment. Typically, a ROI above 15% is considered good in most commercial sectors.
How is ROI different from ROE (Return on Equity)?
ROI measures the return on the total investment, whereas ROE measures the return on shareholders’ equity. ROE = Net Income / Shareholder’s Equity.
Can ROI be negative?
Yes, an ROI can be negative if the costs exceed the gains from the investment, indicating a loss.
How often should ROI be calculated?
ROI should be calculated periodically, such as monthly, quarterly, or annually, to assess the ongoing performance of investments.
What are limitations of ROI?
ROI does not consider the time value of money, risk factors, or secondary costs and benefits, which can lead to oversimplified investment decisions.
- Rate of Return (RoR): The gain or loss on an investment over a specified period, expressed as a percentage of the investment’s cost.
- Return on Invested Capital (ROIC): A measure of the return earned on capital invested in a business, calculated by dividing the net income after taxes by the total invested capital.
