Markup Calculator
Turn your product cost and markup percentage into a selling price, and see the real margin you end up with.
How it works
Selling price = Cost × (1 + Markup ÷ 100)
A 100% markup doubles your cost (often called keystone pricing) but gives a 50% margin, not 100%. Sellers often mix up the two, which leads to underpricing. Check the margin line below the price before you publish a product.
