What Is an ROI Calculator?
An ROI (Return on Investment) Calculator is a financial tool that calculates how much profit or loss you earn from an investment relative to its cost.

ROI Formula (Basic Math Behind It)
The calculator is based on this simple formula:ROI=CostGains–Cost×100
Where:
- Gains = Money you earned from the investment
- Cost = Money you spent on the investment

This means you earned a 25% return on your investment.
