Why breakeven ROAS matters more than ROAS
Breakeven ROAS = 100 ÷ gross margin %. At 40% margin you need 2.5x just to break even - so a "3x ROAS" campaign is only clearing a thin real profit, and a 2x campaign is losing money while looking respectable. This single number is why two stores can run identical ads and one gets rich while the other quietly bleeds.
