Markup vs Margin: What Is the Difference and Which Should You Use?

The core difference

Both metrics measure how much profit you make on a sale. The difference is the denominator. Markup asks: what percentage of my cost is my profit? Margin asks: what percentage of my revenue is my profit? Because cost is always lower than selling price, markup percentages are always higher than margin percentages for the same transaction. A product that costs 10.00 and sells for 15.00 has a 50% markup and a 33.3% margin - both describe the same 5.00 profit.

Markup formula

Example: cost 10.00, selling price 15.00. Markup = (15 - 10) / 10 x 100 = 50%. To find the selling price from a target markup: selling price = cost x (1 + markup / 100). To hit a 100% markup on a 10.00 item: 10 x (1 + 1.00) = 20.00. Markup is most commonly used in wholesale, manufacturing, and cost-plus pricing where you start with a known cost and add a percentage to arrive at your price.

Margin formula

Example: cost 10.00, selling price 15.00. Margin = (15 - 10) / 15 x 100 = 33.3%. To find the selling price from a target margin: selling price = cost / (1 - margin / 100). To achieve a 40% margin on a 10.00 cost: 10 / (1 - 0.40) = 16.67. Margin is used by most retailers, finance teams, and investors because it tells you directly what percentage of every sale you keep - which is the number that matters when planning profitability.

Conversion table

Here are common markup percentages and their equivalent gross margin percentages. The relationship is not linear - as markup increases, margin approaches 100% asymptotically but never reaches it.

• 25% markup = 20% margin
• 33% markup = 25% margin
• 50% markup = 33.3% margin
• 100% markup = 50% margin
• 150% markup = 60% margin
• 200% markup = 66.7% margin
• 400% markup = 80% margin

Which to use when

Use markup when you are starting from a known cost and need to arrive at a price quickly - it is the natural direction of travel for manufacturers, wholesalers, and contractors. Use margin when you are analysing profitability, reporting to stakeholders, or comparing your performance to industry benchmarks. Most industry profit benchmarks (gross margin of 40%, operating margin of 15%) use margin, not markup. If a business advisor asks about your margins, they mean margin.

Why the confusion matters

The most common mistake is targeting a 50% markup thinking it means keeping 50% of every sale. In reality, a 50% markup leaves you with 33.3% margin - and after operating costs, very little net profit. A product business targeting 30% net profit typically needs 55-70% gross margin to absorb marketing, fulfilment overhead, and returns. If you price using markup but benchmark against margin targets, you will systematically underprice.

Common mistakes

• Confusing the two in conversations - when a buyer asks for your margins, they mean gross margin. Quoting your markup instead makes your numbers look inflated.
• Applying markup in a margin-driven industry - retail benchmarks and investor metrics use margin. Convert before comparing.
• Forgetting that fees and returns reduce effective margin further - a 50% margin before fees becomes 43% after a 6.5% Etsy fee and a 2% returns allowance.
• Using cost-plus markup for e-commerce - the better approach is to work backwards from a target margin using the full pricing formula.

Use the calculators

The Markup Calculator lets you enter a cost and a markup percentage to find the selling price and resulting margin. The Profit Margin Calculator works in the other direction: enter a selling price and cost to see the gross profit, margin percentage, and markup. Use both to cross-check your pricing before you publish it.
