Margin and markup are two of the most commonly confused terms in business. While they both measure profitability, they do so from different perspectives—and mixing them up can lead to serious pricing errors that cost your business thousands of dollars.
This guide will clearly explain the difference between margin and markup, show you when to use each, and provide conversion formulas so you never confuse them again.
The Critical Difference: Margin is calculated as a percentage of the selling price, while markup is calculated as a percentage of the cost. This fundamental difference means that a 50% markup is NOT the same as a 50% margin.
What is Margin?
Gross profit margin (often just called "margin") expresses profit as a percentage of your selling price. It answers the question: "What percentage of each sales dollar is profit?"
Margin Example:
You sell a product for $100
Your cost is $60
Your profit is $40
Margin = ($40 ÷ $100) × 100 = 40%
This means 40% of your selling price is profit.
Why Margin Matters
- Shows true profitability: Tells you what percentage of revenue you keep
- Industry standard: Most financial analysis uses margin, not markup
- Easier to compare: Allows apple-to-apple comparisons across products and industries
- Better for planning: Helps forecast profit from sales projections
What is Markup?
Markup expresses profit as a percentage of your cost. It answers the question: "How much am I adding to my cost to determine the selling price?"
Markup Example:
Using the same numbers as before:
Selling price: $100
Cost: $60
Profit: $40
Markup = ($40 $60) × 100 = 66.67%
This means you're adding 66.67% to your cost to reach the selling price.
Why Markup Matters
- Simpler for pricing: Easy to calculate selling price from cost
- Traditional retail tool: Many retailers think in markup terms
- Inventory valuation: Helps calculate potential revenue from inventory
- Quick mental math: "I'll apply 50% markup" is easier than calculating backwards from margin
Side-by-Side Comparison
| Aspect | Margin | Markup |
|---|---|---|
| Based On | Selling Price (Revenue) | Cost |
| Formula | Profit ÷ Selling Price | Profit ÷ Cost |
| Maximum | 100% (if cost is zero) | Unlimited |
| Common Use | Financial analysis, reporting | Pricing, quick calculations |
| Question Answered | What % of sales is profit? | How much to add to cost? |
| Industry Preference | Finance, accounting, analysis | Retail, wholesale, manufacturing |

This is where businesses get into trouble. Many people assume a 50% markup equals a 50% margin, but they're very different:
Example: $60 Cost Product
If you apply 50% markup:
Selling Price = $60 × 1.50 = $90
Profit = $30
Margin = ($30 ÷ $90) × 100 = 33.33%
If you want 50% margin:
$60 cost needs to be 50% of selling price
Selling Price = $60 ÷ 0.50 = $120
Profit = $60
Markup = ($60 ÷ $60) × 100 = 100%
See the difference? A 50% markup gives you only a 33.33% margin, while a 50% margin requires a 100% markup!

Quick Reference Conversion Table
| Markup % | Margin % | Example: $60 Cost |
|---|---|---|
| 25% | 20% | Sell at $75 |
| 50% | 33.33% | Sell at $90 |
| 75% | 42.86% | Sell at $105 |
| 100% | 50% | Sell at $120 |
| 150% | 60% | Sell at $150 |
| 200% | 66.67% | Sell at $180 |
When to Use Each
Use Margin When:
- Analyzing profitability: Comparing products or business performance
- Financial reporting: Creating income statements or reports for stakeholders
- Setting targets: "We need to achieve 40% margins"
- Benchmarking: Industry standards are typically reported in margin
- Calculating from revenue: You know sales and want to know profit
Use Markup When:
- Setting prices: "Take cost and add 60% markup"
- Quick calculations: Simpler math for frontline staff
- Inventory pricing: Marking up wholesale costs to retail
- Traditional retail: Many retail systems are built around markup
- Calculating from cost: You know cost and want to determine price
Pro Tip
Many successful businesses use both: markup for daily pricing decisions (easy for staff to apply), and margin for financial analysis and reporting (better for understanding true profitability).
Common Scenarios
Scenario 1: You Know Cost and Desired Margin
Question: Product costs $50, you want 40% margin. What's the selling price?
Scenario 2: You Know Cost and Want to Apply Markup
Question: Product costs $50, you apply 80% markup. What's the price and margin?
Scenario 3: You Know Selling Price and Cost
Question: Selling at $100, costs $60. What are markup and margin?
Avoiding Costly Mistakes
Here are the most common errors businesses make:
- Using markup when you mean margin: "I need 50% margins" but applying 50% markup gives you only 33% margin
- Inconsistent terminology: Sales uses markup, finance uses margin, leading to miscommunication
- Wrong discounting math: A 20% discount on a 20% margin product doesn't break even—it loses money
- Not tracking both: Understanding both provides complete picture of pricing and profitability
Conclusion
Understanding the difference between margin and markup is essential for pricing products correctly and analyzing profitability accurately. Remember:
- Margin is profit as % of selling price (better for analysis)
- Markup is profit as % of cost (easier for pricing)
- They measure the same profit but from different starting points
- A given markup percentage will always yield a lower margin percentage
- Use both strategically: markup for pricing, margin for analysis
