ROI Calculator

ROI (Return on Investment) is calculated as ((return value - investment cost) / investment cost) x 100. A positive ROI means your investment generated profit, while a negative ROI indicates a loss. For example, investing $1,000 and receiving $1,500 back yields a 50% ROI.

A good ROI depends on the context. Stock market investments historically average 7-10% annually. Real estate may target 8-12%. Marketing campaigns often aim for 200-500% ROI. Any positive ROI means you earned more than you invested.

The payback period estimates how long it takes to recover your initial investment. When you provide monthly revenue, the calculator divides the investment cost by the monthly revenue to determine the number of months needed to break even.

This calculator provides a simple ROI calculation without adjusting for inflation or time value of money. For time-adjusted returns, you would need to use metrics like NPV (Net Present Value) or IRR (Internal Rate of Return).
