How break-even ROAS works

Allowable ad spend is contribution after the entered referral fee and order costs. Target ROAS reserves the desired profit before calculating affordable ad spend.

The editable 15% referral fee is a planning example, not a standard rate. Walmart referral fees vary by category and selling price; verify your category rate.
