What Is ROI and Why Does It Matter?
ROI (Return on Investment) is a general performance metric that shows, as a percentage, how profitable an investment was. The formula is: ((Gain − Investment Cost) ÷ Investment Cost) × 100. Unlike ROAS, ROI isn't limited to ad spend — it can be used to evaluate a website investment, a software project, or any business decision.
A positive ROI means your investment covered its cost and turned a profit, while a negative ROI means you took a loss. Defining your target ROI before starting a project — a corporate website, a mobile app, or ad management — helps you manage your budget correctly.
