Markup vs Margin: The Difference That Protects Your Pricing
Markup and margin describe the same dollar profit from two different reference points. Confusing them is one of the most expensive pricing mistakes a business can make. This page provides the definitions, formulas, a clear table and the classic numerical example.
After you understand the difference, use the free Discount & Markup Calculator to compute either figure (or convert between them) from your actual costs and prices.
Definitions
Expressed as a percentage of cost.
Expressed as a percentage of selling price.
The numerator is identical. The denominator changes. That single change produces different percentages.
Classic Example
Cost = $50
Selling Price = $100
| Metric | Calculation | Result |
|---|---|---|
| Markup | (100 − 50) ÷ 50 | 100 % |
| Margin | (100 − 50) ÷ 100 | 50 % |
A 100 % markup is only a 50 % margin. Anyone who sets a “50 % markup” thinking they will earn a 50 % margin will actually earn a 33.3 % margin and may underprice relative to their true target.

When to Use Each
- Markup – convenient when starting from cost and building a selling price.
- Margin – the language of financial reporting, industry benchmarks and residual-profit analysis.
Most external comparisons use margin. Internal pricing often starts with markup and should be validated by converting to margin. See the markup calculator and profit margin calculator pages for the individual tools, and the retail pricing strategy page for how both fit into a broader pricing approach.
