THREE NUMBERS. KNOW THE MOST YOU CAN PAY FOR A CUSTOMER.

Enter one product’s selling price, what that order costs to deliver and what you currently pay to acquire a customer. See the ROAS required to break even—and the real profit or loss on each sale.

Use one typical order, enter every amount in the same currency and keep every figure on the same tax basis.

Break-even CPA = selling price − cost per order before advertising. For a positive margin, break-even ROAS = selling price ÷ break-even CPA. Profit or loss after ads = selling price − cost per order − CPA.

If the order costs as much as or more than its selling price before advertising, no positive advertising budget can make that order profitable. Losses remain visible in the calculator.
