Enter your price and costs to see profit per order, gross margin and the net margin that actually pays your bills.
Your margin per order
Net margin after fees, shipping and ad cost is the number that actually pays your bills.
Indicative estimate based on your inputs. Real margins vary with returns, discounts, taxes and how you allocate ad spend across orders.
How the ecommerce margin calculator works
Many online sellers track gross margin (price minus cost of goods) and assume the rest is profit. In reality, payment processing, platform fees, shipping and advertising each take a cut before anything reaches your bank account. This calculator layers all of those costs onto a single order so you can see what is genuinely left.
Gross margin shows the headroom you have before selling costs. Net margin is what survives after the payment and platform fee percentage, the shipping cost, and the ad spend attributed to that order. A product can show a healthy 60% gross margin and still lose money once a €6 ad cost and a €4 shipping bill are subtracted, which is why the net figure is the one to watch when you set prices or plan discounts.
Gross margin is (selling price minus cost of goods) divided by price. Net margin also subtracts payment and platform fees, shipping and ad cost per order, then divides the remaining profit by price. Net margin reflects what you actually keep.
