What is ROI?

ROI stands for Return on Investment. It is a financial metric that measures the potential gain made on an investment concerning its cost. ROI is usually expressed as a percentage or a ratio of the amount of money gained relative to the cost of the investment.

Calculate Return on Investment

The formula for calculating ROI is straightforward. ROI is calculated by dividing the gain made from an investment by its cost and then expressing it as a percentage.

ROI = (Gain from Investment – Cost of Investment) / Cost of Investment x 100

For instance, let’s say you invested $10,000 in a stock and sold it for $11,000 after two months. The gain from this investment was $1,000, and the cost of investment was $10,000. Therefore, the ROI on this investment was (1,000 / 10,000) x 100 or 10%.

Interpreting ROI

The ROI percentage indicates the potential to make a profit on an investment in terms of the cost of that investment. A positive ROI percentage indicates that the investment has the potential to earn a profit. On the other hand, a negative ROI percentage suggests a loss on the investment. A higher ROI percentage means a higher potential return, while a smaller ROI means a lower return.

What ROI Means for Investors

Investors use ROI as a basic tool to evaluate the profitability of an investment, and it helps them compare the profitability of multiple investments. ROI helps investors to determine the most profitable investments concerning the cost. Aside from monitoring and evaluating ongoing investments, ROI can also be used to evaluate potential investments.


ROI is an essential concept in the finance industry that every investor should understand. It is a metric used to measure the potential gain made on a particular investment concerning its cost. While the formula for calculating ROI is simple, the interpretation of the ROI percentage is crucial as it indicates whether the investment is profitable or not. ROI can be used to make investment decisions, assess profitability, and compare between different investment options. By understanding how ROI works, you can make better investment decisions that can grow your wealth over time.
