Break-Even ROAS
The specific ROAS a brand must hit to cover product costs without generating profit or loss, calculated as 1 divided by gross margin percentage.
Your campaign reports 3.2x ROAS and the algorithm is stable. Pull the actual margin on what sold and the number looks different. For a brand at 30% gross margin, 3.2x is breakeven.
The formula is: 1 ÷ gross margin %. A brand at 50% margins breaks even at 2x. A brand at 25% margins needs 4x just to cover product costs.
How it shows up in the wild
Purple Circle Digital (D2C fashion, Meta Ads case study, India): A kurta campaign at 4.2x ROAS was costing the brand money. A 38% return rate reduced net revenue to 62% of the Ads Manager figure, per the agency’s published case study. The campaign was paused after the break-even ROAS was recalculated on net revenue.
Vence Media (fashion brand, Meta + Google, cross-channel): A break-even ROAS of 1.56 was the floor set by the brand’s gross margin. The account hit 4.51x blended ROAS across Meta and Google, generating over €1 million in sales from €228,924 in spend. Knowing the floor before launch set the conditions for scaling.
Why it matters
Fashion and apparel D2C brands typically run gross margins of 25–35% after returns and discounts are netted out. My hunch is that most accounts running Meta or Google campaigns at 2.5–3.5x ROAS believe they are performing. At those margins, 2.5–3.5x is the breakeven zone, not a growth signal.
I think the most underused version is per-SKU break-even floors. A product at 60% margin and a product at 20% margin don’t share a floor. Blending them into one account-level ROAS target hides which campaigns are destroying value.

Frequently asked questions
Is break-even ROAS calculated on gross margin or contribution margin? Gross margin is the standard starting point. Contribution margin (gross margin minus shipping, returns, and transaction fees) gives a tighter floor. For high-return categories like fashion, the gap between the two can push the real break-even 1–2 ROAS points higher than the gross-margin formula suggests.
Can you run below break-even ROAS intentionally? Yes, when LTV significantly exceeds first-order margin. A subscription brand losing $10 per acquisition but earning $120 over 12 months is making a rational trade. The bet requires a verified LTV number — not an optimistic projection.
Does break-even ROAS change by platform? The formula is the same across platforms. What varies is which costs you include: some brands calculate it against COGS only; others fold in platform fees and fulfillment. A consistent internal definition matters more than which costs you include.
