What the result means
Break-even ROAS is 1 divided by the contribution margin percentage available to cover ad spend. For example, a 40% contribution margin implies a 2.5 ROAS break-even point.
Important considerations
- Use contribution margin, not a headline margin that excludes fulfilment, payment or product costs.
- The result excludes fixed costs, cash timing and attribution differences.
- A target ROAS above break-even is not automatically profitable at business level.
Worked example
If contribution margin is 40%, break-even ROAS is 2.5 before fixed costs and other overheads.
