Calculation Formula
Net profit = selling price - product cost - shipping - packaging - platform fees - ad cost - refund loss - other costs.
Net margin = net profit / selling price. The break-even price includes percentage-based fees such as commission, payment fees, and refund loss.
If you also have storage fees, creator commission, exchange loss, or withdrawal fees, add them to fixed fees or other costs.
FAQ
How do I calculate ecommerce net profit?
Subtract product cost, shipping, packaging, platform commission, payment fees, ad cost, refund loss, and other order-level costs from the selling price.
What is the difference between gross margin and net margin?
Gross margin only compares selling price and product cost. Net margin includes marketplace fees, logistics, packaging, ads, and after-sales loss, so it is closer to real profit.
Why calculate the break-even price?
The break-even price is the minimum price where net profit is zero. It helps avoid promotions or ads that generate sales but lose money per order.
