Markup calculator
Turn a cost into a price with a markup, check the markup on a price you already have, or translate markup into margin. Then see how much of it survives the platform fee.

Markup formulas
- Markup % = (price − cost) ÷ cost × 100
- Price = cost × (1 + markup)
- Margin = markup ÷ (1 + markup)
Example: a pair of boots bought for $12 at a thrift store, marked up 150%, lists at $30. The gross margin is 60%. After eBay’s 13.6% and $0.40, $13.52 of the $18 gross profit is left, before the shipping label.
Same dollars, two percentages
Margin divides profit by the price. Markup divides it by the cost. Drag the sliders and watch the profit block stay the same size while the two percentages drift apart.
Profit$20.00
Margin (÷ price)40.0%
Markup (÷ cost)66.7%
A 50% markup is only a 33.3% margin. Margin can never reach 100%; markup has no ceiling.

Questions sellers ask
How do you calculate markup?
Markup = (price − cost) ÷ cost × 100. An item bought for $20 and sold for $30 has a 50% markup.
How do I find the price from a markup?
Price = cost × (1 + markup). A $20 item with a 150% markup sells for $50.
Is a 100% markup the same as a 50% margin?
Yes. Doubling the cost (100% markup) means half the price is profit, a 50% margin, before fees.
Why is my markup high but my profit low?
Markup usually ignores selling costs. A 100% markup on a $10 item sold on eBay leaves about $5.70 after the 13.6% fee and $0.40 order fee, before shipping.
What markup do resellers use?
Thrift and garage-sale resellers often aim for 3× to 5× cost (200%–400% markup) on cheap items so that fees, shipping and unsold stock are covered. Retail commonly uses keystone pricing, a 100% markup.
