How it works

• Profit per sale = price − cost per sale (product, packaging, shipping and fees).
• CPA = cost per click ÷ conversion rate, if you don't know your cost per purchase.
• Sales = budget ÷ CPA. Revenue = sales × price.
• ROAS = revenue ÷ budget. Break-even ROAS = price ÷ profit per sale.
• Max profitable CPA = profit per sale. Profit = sales × profit per sale − budget.

Profit is before fixed costs. These are estimates: switch to your real cost per purchase once you have a week or two of data.
