The calculator

Target CPA Calculator

Use averages from your last 3 months. Per-order numbers, not totals.

Total store revenue ÷ number of orders, over your last 3 months.
What the products in one average order cost you to buy or make. Product cost only — no ad spend, salaries, or tools.
Your average out-of-pocket shipping + packaging cost per order. If customers pay for shipping and it covers your cost, enter 0.
Your costs are higher than your AOV. You lose money on every order before you spend a dollar on ads. Fix the offer before you fix the ads.
