What your ads actually earn.

ROAS says how much revenue came back. Contribution margin says how much of it you keep once the product, the ads and the fees are paid for. Plug in last month and see where you stand.

Ad CM = Paid revenue − COGS − Ad spend − Fees

Break-even ROAS = Paid revenue ÷ (Paid revenue − COGS − Fees)

Paid revenue: orders your ad platforms attribute to ads, ideally checked against Shopify.
COGS: landed cost of the units sold, including freight, duty and royalties.
Fees: payment processing plus the shipping you pay for.
