The target keeps your entered contribution before fixed overhead and taxes. It does not establish net profit.

A dash means the ratio has no valid denominator or no positive allowable ad budget.

WHAT TO DO WITH THISUse the target as a test boundary.

Compare observed order cost against your economics over a consistent period. Account for attribution lag and refunds before reallocating spend.

THE METHOD / WHAT IS INCLUDED

Understand the number
before you act on it.

Contribution before ads = revenue − product, delivery, fees, and return costs. Break-even ad cost per order equals positive contribution before ads. Target ad cost subtracts the contribution you want to keep. Revenue ROAS thresholds divide revenue per order by the relevant positive ad budget. Campaign contribution = orders × contribution before ads − ad spend. This excludes fixed overhead, taxes, repeat purchases, and costs not entered. Cost per order is not necessarily customer acquisition cost.

Defaults are illustrative, not industry benchmarks. Choose inputs from the same reporting scope. A calculated opportunity is a question to test, not a guaranteed result.
