ROI Calculator
Calculate return on investment in seconds. Enter the amount you invested and the amount you got back to see your net profit and ROI percent.
Return on investment in plain terms
ROI tells you how much you earned compared to what you put in. You find it by dividing your net gain by the amount invested. An ROI of 60 percent means you made 60 cents for every dollar you spent. It works for ad campaigns, equipment, hiring, or any spend where you can measure what came back.
Use ROI to compare options
ROI shines when you compare choices. A campaign that returns 40 percent beats one that returns 15 percent, even if the bigger one moved more cash. The percent puts every option on the same footing. The return multiple shown here is another quick read: a 1.6x return means you got 1.6 dollars back for every dollar in.
How to use it
Enter the amount invested and the total you received back. The tool shows your ROI percent, your net gain in dollars, and the return multiple. For marketing spend specifically, the ROAS Calculator frames the same idea as revenue per ad dollar.
