What this number means
Break-even ROAS is gross order value divided by the ad spend the order can still afford. It is a unit-economics limit, not a platform target suggestion.
Test a promotion
Change price, creator commission or return assumptions to see whether the offer still has room for advertising.
Compare to actual performance
Use the result with the profit calculator when you want to translate an observed ROAS into per-order profit.

Break-even ROAS questions
These answers describe the visible calculator inputs and its limits.
What is break-even ROAS?
It is gross order revenue divided by the maximum advertising spend the order can absorb before profit becomes zero.
How are returns treated?
The model removes the contribution from returned orders and subtracts the entered return cost, so returns increase the break-even ROAS.
Does this calculator include fixed costs?
No. Staff, software and other fixed costs are not included because this is a per-order unit-economics calculation.
Is my information uploaded?
No. The calculator runs locally in the browser and does not upload the values entered.
