How much of your ad spend never comes back?

Three numbers you already know. You get your break-even ACOS and what your ad-attributed sales earn or lose, monthly and annualised.

  • Your break-even ACOS, which is the number most reports never show you
  • What your ad-attributed sales actually earn after the spend that bought them
  • The annualised figure, which is usually the one that changes the decision

Gross margin means what is left after COGS, Amazon referral and FBA fees, and freight. Before any advertising.
