Breakeven ROAS

What is breakeven ROAS? Breakeven ROAS is the minimum ROAS at which your ads stop losing money — calculated as 1 divided by your contribution margin percentage. A brand with 50% margins breaks even at 2x ROAS. A brand with 25% margins needs 4x. Below that point, every additional ad dollar loses money. It is the most underused metric in ecommerce advertising because most operators don't actually know their contribution margin.

Most media buyers set ROAS targets based on industry benchmarks or arbitrary round numbers rather than their actual cost structure. A brand targeting 3x ROAS because it sounds good might discover their breakeven is 3.2x — meaning every campaign they thought was profitable was losing money.

This calculator computes your exact breakeven using real per-order costs: COGS, shipping, payment processing, and additional variable costs. The output is the precise threshold that separates profit from loss. Set every campaign against this number. Anything above makes money. Anything below burns cash.

If your breakeven is uncomfortably high (above 4x), the solution is not higher targets — it is reducing your cost structure through better supplier pricing, lower shipping costs, or improved conversion rates that bring down effective CPA. Pair this with the Contribution Margin calculator to see exactly where your costs are highest.
