Profit margin
Definition
Gross margin vs net margin
Gross margin is revenue minus cost of goods sold, as a percentage. It tells you whether the products themselves have room to make money. Net margin takes out everything else too - payment fees, shipping you absorb, returns, ad spend and fixed costs - and tells you whether the business makes money.
The gap between the two is where stores get surprised. A 60% gross margin can shrink to a single-digit net margin once ads and shipping are counted, and the store owner watching gross margin never sees it happen.
What is a good profit margin for a Shopify store?
There is no universal number, and be suspicious of anyone quoting one. Margin depends on what you sell and how you sell it: digital products carry almost no product cost, dropshipping stacks thin margins against paid traffic, and own-brand physical products sit in between, with ad spend usually the deciding cost.
A more useful test than any benchmark: is your net margin positive after every cost including ads, is it stable or improving month over month, and does it survive your return rate? A store that can answer yes to all three is healthy at almost any absolute number. Compare against your own history - it is the only benchmark built on your actual costs.
How to calculate yours
Net margin is net profit divided by revenue, times 100. The maths is trivial; the work is collecting every cost so the profit number is real. Miss the payment fees or the returns and your margin reads a few points better than it is.

Example
A $100 order: $40 product cost gives a 60% gross margin. Take out a $3 payment fee, $8 shipping and $15 ad spend and net profit is $34 - a 34% net margin on that order.
