ROI stands for Return on Investment, and it is a measure used to evaluate the efficiency or profitability of an investment. It is calculated by dividing the net profit of the investment by the initial cost of the investment, and then expressing the result as a percentage. A higher ROI indicates a more profitable investment, while a lower ROI indicates a less profitable investment. It is an important metric for businesses and investors to assess the success of their investments and make informed decisions about future investments. **
