ROI (Return on Investment)

What is ROI (Return on Investment)?

ROI is a metric that expresses how much money a company has earned compared to how much it has invested. It is used to evaluate the effectiveness of investments in marketing, technologies, employees, or projects. ROI is usually expressed as a percentage, which allows easy comparison of different investments. It does not focus only on revenue, but on real profit after deducting costs. It is one of the most important indicators of successful business decisions.

Why It Matters

ROI helps companies understand which activities bring real value and which do not. It enables rational, data-driven decisions instead of emotional ones. Thanks to ROI, an entrepreneur can determine whether it is worth investing in advertising, a website, or a new product. It helps optimize budgets and shift investments where they have the greatest impact. Monitoring ROI is absolutely crucial for company growth.
