How it works
Break-even ROAS is the return on ad spend at which an order pays exactly for itself — the point where the profit left after goods, shipping and fees covers the ad spend that produced the order. A $89 product costing $31 in goods, $9 in shipping and 3% in fees keeps $46.33; dividing price by that margin gives a break-even ROAS of about 1.92x. Any campaign reporting less is buying revenue at a loss no matter how impressive the dashboard looks, which is why this number — not a generic target — is the floor every scaling decision stands on. The arithmetic is simple; the discipline is not. Platform-reported ROAS runs hot under generous attribution, so hold campaigns to your break-even multiple under the same window you use internally. Discounting raises the bar viciously: cut the price 20% and the contribution margin shrinks far faster in proportion, pushing the required ROAS past what most campaigns can deliver. The calculator also states the same fact in CPA language — maximum ad cost per order — and, given your current ad cost per order, shows actual ROAS and profit or loss on each sale. Remember the boundary: break-even covers variable costs only. Rent, payroll and software sit outside this math, so a store hovering at break-even ROAS is funding its ads, not itself.Formula
Break-even ROAS = price / (price - product cost - shipping - payment fees)
Tips
- Set campaign target ROAS above break-even, never equal to it — fixed costs exist.
- Recalculate after every price change; discounting raises break-even sharply.
- Convert to max CPA for bidding: it is the same number advertisers bid against.
- Compare platform ROAS to break-even under one attribution window, always.
- Above break-even, profit per order tells you how much testing budget you truly have.
Frequently asked questions
What is break-even ROAS?
The return on ad spend at which an order exactly pays for itself: ad revenue where the margin left after goods, shipping and fees equals the ad cost. Below it, every incremental order loses money however good revenue looks.
How do you calculate break-even ROAS?
Divide selling price by contribution margin per order. A $89 product with $31 goods, $9 shipping and 3% fees keeps $46.33, so break-even ROAS is $89 / $46.33 = 1.92x. Equivalently, max profitable CPA equals the margin itself.
What is a good break-even ROAS?
Lower is better — it is a hurdle, not a score. Thin-margin products can demand 4x-6x before breaking even; high-margin ones clear profitability under 2x. Knowing yours turns vague ROAS targets into a real go/no-go line.
Does hitting break-even ROAS mean I'm profitable?
No. Break-even covers variable costs only — rent, salaries and software still need covering. Treat it as the floor beneath which ads destroy money, then aim meaningfully above it so operations get funded too.
Why does discounting raise break-even ROAS?
Because the margin shrinks faster in proportion than the price. Cut a 20%-margin product's price by 20% and contribution collapses toward zero, so the ROAS needed to cover a given ad spend can double — killing the very campaigns the discount was meant to feed.
