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.
