What is Return on Investment (ROI)?
Return on Investment (ROI) is a performance measure used to evaluate the efficiency or profitability of an investment compared to its cost. Think of it as the financial version of a performance appraisal but without awkward conversations or bad coffee.
Definition
ROI is expressed as a percentage and is calculated by dividing an investment’s net profit (or loss) by its initial cost or outlay. It helps investors decide whether to hold an investment, buy more, or use the cash elsewhere—like flipping a house versus flipping pancakes (but pancakes are usually tastier).
The basic ROI formula is:
\[ \text{ROI} = \frac{\text{Net Profit}}{\text{Cost of Investment}} \times 100 \]
ROI vs. Other Metrics
Here’s a comparison between ROI and another popular metric, Net Present Value (NPV), because who doesn’t love a good comparison?
| Metric |
ROI |
Net Present Value (NPV) |
| Definition |
Measures percentage profit of an investment |
Measures total value of all future cash flows |
| Time Factor |
Ignores the time value of money |
Considers the time value of money |
| Expression |
Expressed as a percentage |
Expressed in currency (e.g., dollars) |
| Usage |
Quick comparison of profitability |
Comprehensive assessment of profitability over time |
Example
Let’s say you purchased stocks for $1,000, and after one year, you sold them for $1,500. Your net profit would be $500.
Using the ROI formula:
\[ \text{ROI} = \frac{500}{1000} \times 100 = 50% \]
Congratulations! You’ve made a 50% return. And you can now afford that shiny new smartphone (or maybe a few fancy coffees).
- Net Profit: Total revenue minus total expenses.
- Investment Cost: The initial amount of money invested.
- Opportunity Cost: The potential benefits missed from not choosing the next best investment alternative.
Fun Facts About ROI

- Some investors joke that their ROI stands for “Return on Imagination,” because sometimes thinking outside the box may yield unexpected profits!
