An Introduction to Return on Investment (ROI)
Learn the fundamental metric for judging the profitability of any investment.
What is Return on Investment (ROI)?
Think about baking a cake. You buy ingredients for $10 (your investment), and you sell the cake for $25 (your return). ROI answers a simple question: How much profit did you make in relation to what you spent?
You made a $15 profit on a $10 cost. ROI expresses this relationship as a percentage.
In business, ROI is a performance measure used to evaluate the efficiency or profitability of an investment. It tells you how much "bang for your buck" you got.
Calculating ROI: An Interactive Example
The formula is (Net Profit / Cost of Investment) x 100. Let's see how changing the numbers impacts the final ROI.
Net Profit
$5,000
Return on Investment (ROI)
50.0%
How to Use ROI: The Decision Rule
ROI is most powerful when used for comparison. You can compare an investment's ROI against a benchmark (e.g., a 10% target ROI) or against the ROI of other potential investments.
Positive ROI
ROI > 0%
The investment is profitable. If the ROI is higher than your target or other options, it's generally a good choice.
Negative ROI
ROI < 0%
The investment lost money. The final value was less than the initial cost. This should be avoided.
ROI: Strengths & Cautions
Strengths of ROI
- Universally Understood: Its simplicity makes it one of the most widely used and easily compared profitability metrics.
- Measures Profitability: It directly links the profit earned to the capital that was required to earn it.
- Versatile: You can calculate ROI for a marketing campaign, a new piece of equipment, or an entire company.
The Critical Flaws
- Ignores Time: A 20% ROI over one year is fantastic. A 20% ROI over ten years is poor. ROI doesn't account for the holding period of an investment.
- Can Be Manipulated: Different accounting methods can change the "Net Profit" or "Cost" figures, leading to different ROI results.
- Doesn't Account for Risk: A high-potential ROI often comes with high risk. ROI alone doesn't give you a sense of the chances of losing money.
