Break-even ROAS calculator
Find the ROAS required to recover spend after variable costs.
Adjust gross margin for shipping or fulfillment, then compare the resulting threshold with current campaign return.

Treat the output as a decision input
A calculator makes assumptions visible. It does not replace attribution quality, margin context or direct account review.
Questions before the audit.
- What is break-even ROAS?
- It is the attributed revenue per dollar of ad spend required to recover that spend at the selected effective margin.
- Why subtract shipping from margin?
- This calculator treats shipping or fulfillment as a variable share of revenue that is unavailable to recover ad spend.
- Can the result be negative?
- Gross profit after ad spend and the gap from break-even can be negative when the current return is below the selected threshold.
Calculate from your numbers.
Effective margin is gross margin minus shipping or fulfillment rate. Break-even ROAS is 100 divided by effective margin. Gross profit subtracts ad spend from revenue after effective margin.
Pressure-test the return threshold.
We will review the margin inputs and attribution evidence used to guide spend.
