A 60.0% markup is only a 37.5% margin, because margin divides the same profit by the price.
How the markup calculation works
Markup is profit divided by cost
Subtract the cost from the price, then divide by the cost. A $25 item sold for $40 has $15 profit and a 60% markup.
Price is cost times (1 + markup)
For a 60% markup on a $25 cost: $25 × 1.60 = $40.
Margin is always lower than markup
Margin divides the same profit by the price instead of the cost. The $15 profit on a $40 price is a 37.5% margin.
A 100% markup doubles the cost
Doubling the cost is a 100% markup and a 50% margin. Keystone pricing in retail works this way.
Worked example. An item costs $25 and you add a 60% markup. The markup is $15, so the selling price is $40. Your margin on that price is $15 ÷ $40 = 37.5%.
Markup FAQ
How do I calculate a markup?
Multiply the cost by the markup percentage and add it to the cost. A 60% markup on $25 is $15, so the price is $40.
How do I calculate markup percentage from cost and price?
Take the price minus the cost, divide by the cost and multiply by 100. ($40 − $25) ÷ $25 = 60%.
What is the formula for markup percentage?
Markup % = (selling price − cost) ÷ cost × 100. Selling price = cost × (1 + markup %).
Is a 50% markup the same as a 50% margin?
No. A 50% markup on a $20 cost gives a $30 price and a 33.3% margin. A 50% margin needs a 100% markup.
What markup should a small business use?
It depends on your overhead and trade. For US listed retailers in January 2026, the average gross margin was 33.2% in general retail, about a 50% markup, and 26.3% in grocery, about a 36% markup (NYU Stern, Damodaran). Small shops often need more to cover rent, wages and fees.
What is keystone pricing?
Doubling the cost to set the price: a 100% markup, which is a 50% margin. A $25 item sells for $50. It is a common starting point in retail, adjusted for competition and how fast the item sells.
