Markup vs margin

Markup is based on cost: (price − cost) ÷ cost. Margin is based on price: (price − cost) ÷ price. That’s why markup is always the bigger number: a 100% markup is a 50% margin, and a 50% markup is a 33% margin.

To con­vert: margin = markup ÷ (1 + markup); markup = margin ÷ (1 − margin).

100% = 50%
a 100% markup is a 50% margin: an item that costs $10 sells for $20

Break-even

Fixed costs — rent, soft­ware, ads — don’t change with how much you sell. To cover them you need fixed costs ÷ profit per unit in sales. Ev­ery­thing above that is profit before tax.

03

What’s not included

Margin here is before taxes, mar­ket­place fees and card pro­cess­ing. If you sell on Etsy or take cards, add those per­cent­ages to your cost.

How we calculate

Markup = (price − cost) ÷ cost. Margin = (price − cost) ÷ price. Price from markup = cost × (1 + markup); from margin = cost ÷ (1 − margin). Break-even = fixed costs ÷ profit per sale.
