What does ROI stand for and what does it measure?

The correct choice defines ROI as "Return on Investment" and clarifies that it measures the gain or loss generated on an investment. This metric is crucial in evaluating the efficiency and profitability of an investment by comparing the net profit to the initial cost.

ROI is a widely used performance measure across various sectors because it allows investors and businesses to assess the potential returns from their investments relative to their costs. It helps stakeholders make informed decisions on whether or not to pursue a specific investment by understanding how much they are earning or losing as a percentage of what they invested.

This understanding of ROI is essential for making sound financial decisions, as it provides a clear framework for analyzing the success of investments, comparing various opportunities, and allocating resources effectively.
