Calculate profit per order after supplier cost, shipping, fees, ads and other variable costs — plus margin, ROAS and break-even ad limits.
The calculator starts with selling price and subtracts supplier/product cost, supplier shipping, percentage and fixed payment or platform fees, a returns/refund reserve, advertising cost per sale, and other variable costs. The result is estimated net profit and net margin for one order.
Break-even CPA is the contribution profit available before advertising and represents the maximum modeled ad cost per sale. If your CPA rises above that amount, the modeled order becomes unprofitable. This makes it useful when deciding how much you can afford to pay Meta, TikTok, Google or another ad channel for one purchase.
Actual ROAS is selling price divided by ad cost per sale. Break-even ROAS is selling price divided by break-even ad spend. If actual ROAS is below the break-even level, the modeled order loses money after ads.
Either approach can work as long as you do not count it twice. This calculator separates supplier product cost and supplier shipping so the cost structure is easier to inspect.
Use your expected or observed cost per purchase (CPA). If you have spend and orders instead, divide ad spend by attributed purchases.
Yes. Set ad cost to $0. The calculator will still show pre-ad contribution profit and the maximum amount the order could theoretically support for acquisition.
This version focuses on per-order economics. This version focuses on per-order economics. Use the Break-even ROAS Calculator for dedicated ad-efficiency planning; a monthly profit tracker is planned as a separate tool.
