What break-even ROAS actually tells you
Most stores judge ads against a target somebody else made up — 3x because an agency said so, 4x because it feels safe. Break-even ROAS replaces the guess with your number: the exact return where a campaign stops losing money after product cost, shipping, payment fees, and refunds. Above it, every order contributes margin. Below it, you're paying for the privilege of shipping boxes. Ad platforms won't show you this line, because they don't know your costs. You should know it before you set a single budget.
How it's calculated
Break-even ROAS is the inverse of your contribution margin. Step one: contribution margin per order — AOV minus COGS, shipping and fulfillment, payment processing, a refund allowance, and any other per-order costs. Step two: break-even ROAS = AOV ÷ contribution margin per order. Example: an $80 AOV with $28 COGS, $7 shipping, 2.9% + $0.30 processing, and a 3% refund rate keeps $39.98 per order — a 50.0% margin. Break-even ROAS = 80 ÷ 39.98 = 2.00x. A campaign reporting 2.0x in Ads Manager looks fine and earns exactly nothing.
How to read your number
Under your break-even, every attributed order loses money. At it, you're covering variable costs and contributing zero to payroll, rent, software, or profit. That's why break-even is a floor, not a target — set your working target with the profit field above. One more trap: platform ROAS blends new and returning customers. Returning customers who would have bought anyway inflate the number, which means your true bar for acquisition campaigns is higher than the blended figure. To see what a customer is worth beyond the first order, run the LTV & CAC payback calculator. For the full worked example, read how to calculate break-even ROAS.
Typical ranges
Stores keeping 50–60% contribution margin break even around 1.7–2.0x. At 40% margin the line moves to 2.5x. Below 30% margin you need 3.3x or better just to tread water — at that point most paid programs struggle, and the fix is margin (pricing, COGS, shipping) before media.

And if platform ROAS and your own numbers keep disagreeing, that gap is attribution — we unpack it in Shopify attribution without the theater.

Frequently asked questions
Break-even ROAS is the minimum return on ad spend at which ad-driven revenue exactly covers your variable costs — product, shipping, payment fees, and refunds. Below it a campaign loses money; above it, it contributes profit. The math is AOV ÷ contribution margin per order.
Break-even ROAS is the inverse of your contribution margin, so margin does most of the work. At 50% margin you break even at 2.0x; at 33% margin the line moves to 3.0x. A higher AOV only helps if the extra revenue keeps the same margin percentage — raising AOV with heavier, costlier orders can leave the threshold unchanged.
No. Break-even is where you stop losing money — treat it as the kill line. Target ROAS is break-even plus the profit you actually want: 1 ÷ (contribution margin % − desired profit %). Run campaigns against the target, not the floor.
Compare every campaign to it and cut what sits below the line for long enough to be real. Then look past the first order: the channel with a mediocre ROAS can still be your best if it produces repeat buyers. That's a journey and lifetime-value question, not a platform-report question.
