It depends on your margin. Break-even ROAS = 1 ÷ profit margin, so at a 40% margin you need 2.5× just to break even; profitable campaigns clear that.

ROAS = revenue ÷ spend (a ratio). ROI = (revenue − spend) ÷ spend as a percent. This tool shows both.

What Is the ROAS Calculator?

The ROAS Calculator shows your return on ad spend (revenue ÷ ad spend), your advertising ROI, and — given your profit margin — the break-even ROAS you need just to cover costs, so you instantly see whether a campaign is actually profitable rather than just generating revenue.

How It Works

Enter the revenue a campaign generated, the ad spend, and your profit margin. ROAS, ROI and break-even ROAS update instantly with a profitability verdict.

When to Use It

When evaluating paid campaigns on Google, Meta, TikTok or Amazon, setting target ROAS bids, or explaining to a client why a 3× ROAS can still lose money at a low margin.
