ROI Calculator Explained
An ROI calculator measures return on investment by comparing how much you put in with how much you got back. It gives you both the net profit and the ROI percentage, which makes it easier to compare outcomes across projects, campaigns, or investments of different sizes. This is useful in business analysis, freelance work, marketing spend reviews, and personal finance planning. Instead of only looking at gross return, ROI helps you judge whether the gain was meaningful relative to the original cost.
