What this measures
Break-even ROAS is the return on ad spend at which a campaign makes exactly zero profit — every dollar of ad spend is recovered by the gross profit on the sales it drives, and nothing more.
It's the single most useful guardrail in paid acquisition. Any campaign running below its break-even ROAS is losing money, no matter how good the headline ROAS looks.
The formula
Break-even ROAS = 1 ÷ Gross profit margin (as a decimal).
Worked example
With a 60% gross margin, break-even ROAS = 1 ÷ 0.60 = 1.67×. You need at least $1.67 of revenue per ad dollar just to break even; below that, the campaign is unprofitable.
