Profit Margin vs. Markup: What's the Difference?
5 min read · Related calculators: Profit Margin · Markup
Profit margin and markup are two of the most commonly confused terms in business. They both describe the relationship between cost and price, and they both involve the same numbers — but they are calculated differently and mean different things. Confusing them is one of the most common and costly pricing mistakes a business can make.
The Short Answer
- Markup is the amount added to cost, expressed as a percentage of cost.
- Profit margin is the profit expressed as a percentage of revenue (selling price).
Same numbers, different bases. That's the entire difference — but it has significant practical consequences.
A Simple Example
You buy a product for $60 and sell it for $100. Your profit is $40.
Same transaction. Same profit. But the markup is 66.7% and the margin is 40%. Neither number is wrong — they're just measuring different things.
Why the Difference Matters
The confusion becomes a real problem when you use one formula but think you're using the other. Here's the classic mistake:
A business owner wants a 30% profit margin. Their product costs $50. They think: "I'll add 30% to my cost." So they set the price at $50 × 1.30 = $65.
But wait — what's the actual margin at $65?
Profit = $65 − $50 = $15. Margin = $15 ÷ $65 = 23.1% — not 30%.
By applying a 30% markup instead of a 30% margin, they've underpriced by nearly 7 percentage points. On a high-volume product, this can mean thousands of dollars in lost profit every month.
The Conversion Formulas
If you know one, you can calculate the other:
Example: 50% markup → 50% ÷ 150% = 33.3% margin
Example: 40% margin → 40% ÷ 60% = 66.7% markup
Quick Reference Table
| Markup % | Profit Margin % |
|---|---|
| 10% | 9.1% |
| 25% | 20% |
| 33.3% | 25% |
| 50% | 33.3% |
| 100% | 50% |
| 200% | 66.7% |
| 400% | 80% |
Which One Should You Use?
Both are valid — the key is to be consistent and to know which one you're using at any given time.
Use markup when:
- You're working in a wholesale or retail context where you buy at a cost price and need to set a retail price
- Your industry uses markup as the standard (e.g., many retail and manufacturing businesses)
- You're calculating prices from cost upward
Use profit margin when:
- You're reporting financial performance (investors and accountants typically use margin)
- You're comparing profitability across different products or businesses
- You're working with a target margin set by your financial plan or investor requirements
The most important thing is to never mix them up. If your accountant says "we need a 40% margin" and you apply a 40% markup, you'll fall short of the target every time.
How to Set a Price for a Target Margin
If you know your cost and want to achieve a specific profit margin, use this formula:
Example: Cost = $50, Target Margin = 30% Price = $50 ÷ (1 − 0.30) = $50 ÷ 0.70 = $71.43
Verify: Profit = $71.43 − $50 = $21.43. Margin = $21.43 ÷ $71.43 = 30%. ✓

Key Takeaways
- Markup is profit as a percentage of cost. Margin is profit as a percentage of revenue.
- The same profit produces a higher markup percentage than margin percentage — always.
- Applying a markup when you meant to apply a margin will result in underpricing.
- To price for a target margin, use: Price = Cost ÷ (1 − Margin %).
- Be consistent — pick one and use it throughout your pricing model.
