Frequently asked questions
How do markup and margin differ?
Markup divides profit by cost; margin divides profit by selling price. A cost of 40 and a selling price of 60 give 50% markup and 33.33% margin.
Are selling fees included?
No. These are gross figures before platform fees, shipping and overhead. Use a fee calculator to estimate profit after those costs.
