What is break-even ROAS?
Break-even ROAS is the minimum ROAS needed before ad spend stops losing money on a variable-cost basis.
Direct answer
Break-even ROAS is usually calculated as 1 divided by contribution margin rate. If contribution margin is 40%, break-even ROAS is 2.5.
Why this matters
It converts finance reality into a media-buying threshold so teams can scale campaigns without guessing.
What to check
Use this term as an operating checkpoint, not just a glossary definition.
- Use contribution margin after product cost, payment fees, shipping subsidy, and expected refunds.
- Set different thresholds for hero products, bundles, and clearance items.
- Review the threshold whenever costs, prices, or return rates change.
Common mistake
The mistake is calculating break-even ROAS from gross margin only and forgetting shipping, payment fees, returns, and discounts.
FAQ
Is break-even ROAS the same as target ROAS?
No. Break-even ROAS is the floor. Target ROAS should be higher when you need profit, cash buffer, or budget for future growth.
Should every SKU use the same break-even ROAS?
No. Different SKUs have different cost, shipping, return, and upsell profiles.
How do discounts affect break-even ROAS?
Discounts reduce contribution margin, so the required break-even ROAS rises unless conversion rate or AOV improves enough.
