ROI Calculation Formula
ROI is calculated as follows:
ROI = (Gain from Investment - Cost of Investment) / Cost of Investment
This formula is simple to understand, and you don’t need to be a math genius to get it. If you’re still struggling, think of it as a recipe for a delicious cake, where the gain from investment is the taste, and the cost of investment is the ingredients and labor.
Categories of ROI Calculations and Results Interpretation
It’s important to understand the interpretation of ROI results. The following table outlines different categories/types/range/levels of ROI calculations:
Category | Range / Type / Level | Interpretation |
---|---|---|
Good | 100% or more | You’re making a profit! |
Average | 0% to 99% | You’re breaking even or making a small profit. |
Bad | Negative ROI | You’re losing money. Quick, change your strategy! |
Examples of ROI Calculations
To help you understand better, let’s look at some examples of ROI calculations:
Individual | Investment | Gain | Cost | ROI Calculation |
---|---|---|---|---|
John | $500 | $750 | $500 | ($750 – $500) / $500 = 50% |
Sarah | £1000 | £1200 | £1000 | (£1200 – £1000) / £1000 = 20% |
Bob | €5000 | €4000 | €5000 | (€4000 – €5000) / €5000 = -20% |
As you can see, John’s investment resulted in a 50% ROI, which means he made a profit. Sarah’s investment resulted in a 20% ROI, which is still good, while Bob’s investment resulted in a negative ROI, which means he lost money.
