How Does This Calculator Work?
ROI is calculated as (gain − cost) ÷ cost × 100, expressing your net profit as a percentage of what you originally invested.
ROI is one of the most common ways to evaluate whether an investment paid off. This calculator gives you the percentage return from your total gain and original cost.
Example Calculation
Investment Example
