Selling online looks simple until fees, ads and returns take their cut. This calculator shows your true profit per order after product cost, shipping, platform fees, advertising and returns — plus the break-even ROAS your ads must beat to make money.

Profit per order, margin and break-even ROAS for online sellers.
How it works
Platform fee = price × fee%. Profit per order = price − product cost − shipping − platform fee − ad cost. The returns adjustment multiplies that profit by (1 − returns%), a simple way to spread the cost of returned orders across all orders. Break-even ROAS = price ÷ (price − product cost − shipping − platform fee): below this return on ad spend, ads lose money.
