Campaign safety check
Know the minimum ROAS before a campaign can be profitable
Break-even ROAS connects advertising performance to margin. It helps you spot campaigns that look impressive in revenue reports but are unlikely to produce profit after costs.
Reference points
Methodology
- Use gross margin after product cost, shipping support, platform fees, and expected returns.
- Divide 1 by gross margin percentage to estimate the ROAS needed to break even.
- Add a safety buffer before scaling because attribution and real costs are rarely perfect.
Practical examples
- At 50 percent gross margin, break-even ROAS is 2.0x.
- At 25 percent gross margin, break-even ROAS rises to 4.0x before overhead.
- If an account reports 3.0x ROAS but your break-even is 3.6x, the campaign likely needs improvement before scaling.
Common mistakes to avoid
- Do not use product margin alone if shipping, returns, or payment fees are meaningful.
- Do not apply one break-even ROAS target across products with very different margins.
- Do not ignore cash flow timing when spend happens before revenue clears.

FAQ
Why can break-even ROAS change over time?
Fee mix, discounts, shipping costs, and product margin changes all shift the margin available to cover ad spend.
Should I include retention in break-even ROAS?
Only if your repeat purchase behavior is stable and measured. Otherwise, use a conservative zero-retention assumption.
Can I run below break-even ROAS?
Sometimes for intentional acquisition campaigns, but only with clear payback tracking and limited budget exposure.
