Frequently asked questions
Why is my profit lower than the price minus my cost?
Platforms charge a commission on the sale price, often a fixed fee per order, and sometimes tax on those fees. This calculator adds all of them so you see the net amount.
Where do I find my commission rate?
Each marketplace publishes its commission table by category. Enter that rate here. Rates change, so check them before you set prices.
