Markup vs Profit Margin: What Is the Difference?
The short answer: markup is calculated as a percentage of cost, while profit margin is calculated as a percentage of revenue. Both numbers describe the same transaction, but they are not interchangeable — confusing them is one of the most common pricing mistakes in business.
| Dimension | Markup | Profit Margin |
|---|---|---|
| Definition | How much above cost you charge | How much of revenue is profit |
| Formula | (Revenue − Cost) / Cost × 100 | (Revenue − Cost) / Revenue × 100 |
| Base | Cost | Revenue (selling price) |
| Typical range | Can exceed 100% | Always between 0% and 100% |
| Best used when | Setting prices from a known cost | Reporting profitability to stakeholders |
What Is Markup?
Markup expresses the price increase applied on top of the cost of a good or service. A product that costs $40 to produce and sells for $60 has a markup of 50%, because the $20 profit is 50% of the $40 cost.
The formula is:
Markup % = (Selling Price − Cost) / Cost × 100
Markup is the natural language of purchasing and manufacturing departments: "We mark up every item by 40%." Use the Markup Calculator to find your selling price, cost, or markup percentage instantly.
What Is Profit Margin?
Profit margin (gross margin) expresses profit as a share of the selling price. The same $40 product selling for $60 has a profit margin of 33.3%, because the $20 profit is 33.3% of the $60 revenue.
The formula is:
Margin % = (Selling Price − Cost) / Selling Price × 100
Margin is the language of finance, accounting, and investors. Income statements show margin, not markup. Use the Profit Margin Calculator to convert between cost, revenue, and margin percentage.
Key Differences
Because markup and margin share the same numerator (profit) but divide by different denominators, a given markup always translates to a lower margin percentage. Examples:
- 25% markup → 20% margin
- 50% markup → 33.3% margin
- 100% markup → 50% margin
The relationship is: Margin = Markup / (1 + Markup) and Markup = Margin / (1 − Margin).
A business owner who wants a 30% margin but applies a 30% markup will under-price every item and earn only 23% margin instead.
Which Should You Use?
Use markup when you are building a price list from known costs. It is intuitive: "add 40% to cost" is easy to communicate across a team.
Use profit margin when you are analyzing or reporting financial performance. Margins are directly comparable across companies and industries because they are revenue-normalized.
The best practice is to set prices using markup, then verify the resulting margin meets your financial targets. Both the Markup Calculator and the Profit Margin Calculator show both figures side-by-side so you never have to convert by hand.
FAQ
Can markup be higher than 100%?
Yes. A product that costs $10 and sells for $25 has a 150% markup. Margin, by contrast, can never exceed 100% because profit cannot be larger than revenue.
Why do retailers use markup while investors use margin?
Retailers start from a known cost and add a markup to determine price. Investors and analysts receive the revenue figure first and want to know what fraction remains as profit, so they use margin.
Is gross margin the same as profit margin?
Gross margin excludes operating expenses and taxes; net profit margin deducts everything. The formulas above calculate gross margin. The Profit Margin Calculator handles both scenarios.
