01
What is break-even ROAS?
Break-even ROAS is the return on ad spend at which advertising neither earns nor loses money. It depends on one number only — your profit margin. The formula: break-even ROAS = 1 / margin. With a 25% margin you need ROAS 4.0 just to break even; every sale below that loses money.
Margin here means what is left of the selling price after cost of goods, payment fees, shipping and packaging — everything that scales with each order. Fixed costs like salaries or rent are not part of break-even ROAS.
02
Why ROAS 3.0 can still lose money
A ROAS of 3.0 sounds healthy: every dollar of ads brings three dollars of revenue. But revenue is not profit. If your margin is 30%, those three dollars contain only 0.90 of gross profit — while the click cost a full dollar. You are paying 10 cents for every "successful" sale.
That is why comparing ROAS between businesses is meaningless without margins. An electronics store with 12% margin needs ROAS 8.3; a cosmetics brand with 70% margin is profitable from ROAS 1.4. Know your own break-even before judging any campaign.
