ROAS and ROI are often used as if they were interchangeable, but they answer different questions. ROAS focuses on revenue generated by ad spend. ROI asks whether the investment produced profit after costs.
Use the ROAS Calculator when the question is advertising efficiency. Use the ROI Calculator when you need a broader return view.
What ROAS tells you
ROAS shows revenue divided by ad spend. If you spend 1,000 and generate 5,000 in revenue, ROAS is 5x. This is useful for campaign monitoring, but it ignores margin and other costs.
What ROI tells you
ROI includes gain compared with investment. It is better when you need to judge whether a campaign, project, or channel was actually profitable.
Which one should you use?
Use ROAS for quick paid media comparisons. Use ROI for final decisions. If two campaigns have the same ROAS but different margins, ROI can tell a very different story.
