What is ROI and Why Does It Matter?
Return on Investment (ROI) is one of the most important metrics in finance and business. It measures how much profit or loss you made relative to what you invested. Whether you are evaluating a stock, a business idea, a marketing campaign, or real estate — ROI tells you if it was worth it.
