Gross margin only subtracts the direct cost of the product. Overheads like rent, wages, ads and fees come out of this afterward. Need the markup instead? Use the markup calculator.

Frequently asked questions

How do I calculate profit margin from cost and selling price?
Subtract cost from price to get profit, divide by the selling price, then multiply by 100. For a $150 cost and $200 price: (200 − 150) ÷ 200 × 100 = 25% margin.
What is the difference between margin and markup?
Margin is profit as a share of the selling price; markup is profit as a share of cost. The same dollar profit gives a lower margin % than markup %. To go the other way, use the markup calculator.
What is a good gross profit margin?
It varies by industry: grocery and electronics often run 10–25%, general retail 30–50%, and handmade or specialty goods can exceed 50%. Compare against your sector rather than a universal number.
Does gross margin include all my expenses?
No. Gross margin only subtracts the direct cost of the product. Rent, wages, ads and fees come out of that margin afterward and lower your net profit.
Is my data sent anywhere?
No. Every calculation runs in your browser. Nothing you type is uploaded, logged or stored, and the numbers reset when you close the tab.
