About this extension
Margin and markup are not the same number, and mixing them up is the most common way makers underprice their work. Enter what an item costs you, then work from a target margin, a target markup, or a price you already have, and this gives you the selling price, the margin, the markup and the profit on each one.
Made for Etsy sellers, craft fairs and anyone pricing what they make: a 75% markup on a 30 dollar cost is a 52.50 price, and that is only a 42.86% margin.
Everything is calculated in your browser. Nothing you type is uploaded, and the extension asks for no permissions. It is the same calculator as makerkiln.com/markup-margin-calculator.
