📊 How This ROI Calculator Works

This ROI (Return on Investment) Calculator helps you quickly assess the profitability of your investments—whether you’re launching a new product, running a marketing campaign, or evaluating a new business tool.

It takes your total gain or revenue from the investment and subtracts the initial cost, then divides that by the cost, giving you a percentage that represents your return.

Formula Used:

ROI (%) = (Gain from Investment − Cost of Investment​ / Cost of Investment) × 100
