What the result shows

The most you can spend to generate one order before that order stops covering its own costs.

How it is calculated

Subtract product, payment, shipping, fulfilment, returns, and other variable costs from order revenue. Divide order revenue by the amount left for ads.

How to use it

Use this as the minimum ROAS needed to cover the costs entered. Do not treat it as a profitable campaign target.

What this result leaves out

Tax, fixed overhead, and profit from later orders are not included. If repeat purchases are expected to recover acquisition cost, check customer lifetime value and payback separately.
