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.
