Break-even ROAS: the number your CFO needs before scaling spend
BAZ Commerce Engine — proprietaryOct 16, 2026 6 min
Vanity ROAS lies. Break-even ROAS = 1 / contribution-margin%. Below it, every dollar loses money.
Contribution margin = (price − COGS − fees − shipping) / price. Break-even ROAS = 1 / margin. A 55% margin means break-even ROAS 1.8 — spend is only profitable above that line. The BAZ Commerce engine prices media against margin, not revenue.
