ROI Calculator

An ROI (Return on Investment) calculator measures the profitability of an investment by comparing the gain or loss relative to its cost. ROI is expressed as a percentage, making it easy to compare the efficiency of different investments.

This free calculator instantly computes your ROI and net profit or loss. It's useful for evaluating stocks, real estate, business investments, marketing campaigns, or any financial decision where you want to measure returns.

A positive ROI means you made money; a negative ROI means you lost money. The higher the ROI percentage, the more profitable the investment.

1. Enter the amount invested — Your initial investment cost.
2. Enter the amount returned — The total value you received back.
3. View your ROI — See the percentage return and net profit/loss.

ROI = ((Amount Returned - Amount Invested) / Amount Invested) × 100

Example: Invested $10,000, returned $15,000 → ROI = (($15,000 - $10,000) / $10,000) × 100 = 50%
