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

Markup Markup = (Selling Price − Cost) ÷ Cost
Expressed as a percentage of cost.
Margin Margin = (Selling Price − Cost) ÷ Selling Price
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

MetricCalculationResult
Markup(100 − 50) ÷ 50100 %
Margin(100 − 50) ÷ 10050 %

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.

Conversion Formulas

Margin from Markup Margin = Markup ÷ (1 + Markup)
Markup from Margin Markup = Margin ÷ (1 − Margin)

These allow rapid movement between the two views. The markup calculation process is detailed on the how to calculate markup page; the margin process is on the how to calculate profit margin page.

When to Use Each

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.
