Example and tips

A store with a $72 AOV and a 58% gross margin makes $41.76 of margin per order. To keep a third of that as profit, it can spend up to about $28 to acquire a customer. Any campaign with a CPA above $28 is losing money on the first order.

  • Set your max CPA from margin, not revenue. A $72 sale at 58% margin only funds a $28 acquisition, not $72.
  • Decide if you optimize for first-order profit or break-even acquisition. Repeat-purchase brands can afford a higher CPA.
  • If your actual CPA sits above the target, fix conversion rate or AOV first. Cutting ad spend alone rarely closes the gap.
