Learn the crucial difference between profit margin and markup, why businesses confuse them, and how to calculate both correctly.

Here's a confusing situation many business owners face: Your accountant says your profit margin is 25%, but you calculated a 33% markup. Are you confused? You're not alone.
Profit margin and markup are not the same thing — and confusing them can lead to serious pricing mistakes. A business owner recently told me "I mark everything up 100%, so I make 100% profit." That's wrong. A 100% markup actually equals a 50% profit margin.
In this guide, we'll explain the difference clearly, show you the math with real examples, and help you use our calculators to get your pricing right.
Let's start with the basics:
Markup = Percentage you add to your cost
Profit Margin = Percentage of revenue that's profit
Notice: Same scenario, but 50% markup ≠ 33% profit margin. This is the confusion.
| Aspect | Markup | Profit Margin |
|---|---|---|
| Definition | Percentage added to cost | Percentage of revenue that's profit |
| Base | Cost | Revenue/Sale Price |
| Formula | (Profit / Cost) × 100 | (Profit / Revenue) × 100 |
| Always | Higher than margin | Lower than markup |
| Purpose | Pricing decisions | Profitability assessment |
The key insight: Markup and margin use different bases (cost vs. revenue), which is why they're never the same number.
You buy shoes for $40 and sell them for $75:
Markup Calculation:
Markup = ($75 − $40) / $40 × 100 = $35 / $40 × 100 = 87.5%
Profit Margin Calculation:
Profit Margin = ($75 − $40) / $75 × 100 = $35 / $75 × 100 = 46.7%
Same $35 profit, but 87.5% markup vs. 46.7% margin. The retailer uses an 87.5% markup to achieve a 46.7% profit margin.
A store owner thinks: "All my products are marked up 100%, so I must be making 100% profit."
Reality check:
On $100 in sales with 100% markup:
The 100% markup only generates 50% profit margin. This is the most common math mistake in business.
Your profit margin should account for all business expenses, not just product cost:
True Profit Margin = (Revenue − COGS − Operating Expenses − Taxes) / Revenue
Real Example: Restaurant with $10,000 in Daily Sales
Many restaurant owners mark up food 300-400% (yes, 300%!), thinking they'll make 75% profit on food. But after salaries and overhead, they end up with only 5-15% bottom-line profit margin. Understanding this difference prevents business failure.
Markup (%) = (Selling Price − Cost) / Cost × 100
Or rearranged to find selling price:
Selling Price = Cost × (1 + Markup%)
Profit Margin (%) = (Selling Price − Cost) / Selling Price × 100
Or rearranged:
Profit Margin (%) = (Revenue − COGS − Expenses) / Revenue × 100
If you know markup, here's the profit margin (for products with no other expenses):
| Markup % | Profit Margin % |
|---|---|
| 10% | 9.1% |
| 20% | 16.7% |
| 33% | 25% |
| 50% | 33.3% |
| 75% | 42.9% |
| 100% | 50% |
| 150% | 60% |
| 200% | 66.7% |
| 300% | 75% |
See the pattern? Markup is always higher than profit margin for the same product.
It depends on your industry. Higher-cost industries need different markups:
Retail (Clothing)
Restaurants
Wholesale
Software/Services
The key: Don't compare your markup to other industries. Compare your profit margin instead. A restaurant with 10% profit margin might be healthy; a software company with 10% profit margin is failing.
Markup % = (Selling Price − Cost) / Cost × 100
This tells you: "I'm adding X% to my cost"
Profit Margin % = (Selling Price − Cost − Expenses) / Selling Price × 100
This tells you: "Of every dollar in sales, I keep X% as profit"

Q: Which should I focus on for pricing? A: Focus on profit margin, not markup. Markup is how much to add; margin tells you if you're actually profitable. You could have high markup but negative margin if expenses are too high.
Q: Can I have negative margin? A: Yes, if expenses exceed profit. This means you're losing money per sale. This happens if:
Q: Should I increase markup or decrease costs? A: Ideally both. For immediate profit, decrease costs (negotiate supplier prices, reduce waste). For sustainable growth, increase prices (premium positioning) and decrease costs.
Q: Do I need a different markup for different products? A: Yes. Popular items can have lower markup; specialty items need higher markup to offset lower volume. Use our markup calculator to test different prices.
Q: How often should I review my margins? A: Monthly. Costs change, competition changes, and you need to adjust prices accordingly. Even a 1% improvement in margin adds thousands to annual profit.
Q: What if competitors have higher markups than me? A: They might operate at lower volumes, have lower costs, or are less profitable. Don't compare markup. Compare value to customers and profit margin health.
