Definition
Break-even ROAS is the return on ad spend at which a campaign covers its costs exactly, calculated as 1 divided by gross margin. At a 50% gross margin break-even is 2.0x, at 40% it is 2.5x, and at 25% it is 4.0x. Any campaign running below its break-even ROAS is losing money regardless of how the figure looks in the ads dashboard.
How it is calculated
Break-even ROAS = 1 ÷ Gross margin
What to know
Gross margin here should include everything that scales per order: product cost, packaging, shipping and payment processing. Leaving those out produces a break-even number that is wrong in the optimistic direction.
Because it is a ratio, break-even ROAS is awkward to act on inside a campaign. The same fact expressed as maximum CPA, which is gross profit per order, is usually easier to manage against.
