What is ROAS? The definition, formula, and the break-even number your margin demands
Eightx Free Beginner
Cleanly separates 'break-even ROAS' from 'target ROAS,' a distinction most benchmark posts skip straight past.
- Break-even ROAS is the floor; target ROAS should sit meaningfully above it to fund overhead and profit.
- A 3x ROAS is healthy at a 60% contribution margin and a slow leak at a 25% contribution margin, same number, opposite outcome.
- Category margin norms differ a lot, for example many apparel brands net only 18 to 22% CM after returns, which pushes their real break-even closer to 5x.
