Markup vs Margin
Same profit. Different denominators. Mixing them up is the most expensive pricing mistake in retail.
Take a product that costs $40 to make and sells for $60. The profit is $20. Now ask two questions: what percentage of the cost is the profit? And what percentage of the revenue is the profit? The profit is the same $20, but the answers are completely different. $20 is 50% of the $40 cost (markup). $20 is 33.3% of the $60 revenue (margin).
This confusion is not a beginner mistake. It shows up in pricing spreadsheets, supplier negotiations, investor decks, and financial reviews. The fix is simple once you understand the denominators: cost for markup, revenue for margin.
MARKUP
$20 ÷ $40
= 50%
Denominator: what you SPENT
MARGIN
$20 ÷ $60
= 33.3%
Denominator: what you EARNED

Same transaction, two denominators. Markup divides profit by cost. Margin divides the same profit by revenue.

|---|---|---|---|
| 10% | 9.1% | 100% | 50.0% |

| 80% | 44.4% | 1000% | 90.9% |
The Formulas — and Why They Work
Formula 1 — Markup
Markup % = (Selling Price − Cost) ÷ Cost × 100 Selling Price = Cost × (1 + Markup %) Example: $40 × 1.50 = $60; ($60 − $40) ÷ $40 = 50%.
Formula 2 — Gross Margin
Gross Margin % = (Selling Price − Cost) ÷ Selling Price × 100 Selling Price = Cost ÷ (1 − Gross Margin %) Example: $40 ÷ 0.667 = $60; ($60 − $40) ÷ $60 = 33.3%.
Formula 3 — Converting Between Them
Margin = Markup ÷ (1 + Markup) Markup = Margin ÷ (1 − Margin) 50% markup → 33.3% margin. 50% margin → 100% markup.
The Confusion Tax — How Much Has This Mistake Cost You?
If you have been applying margin targets as if they were markup targets, here is the real number.
The most common version: a business sets a 30% margin target but uses the markup formula to calculate prices, pricing as if 30% is markup instead of margin. The result is systematic underpricing.

Markup for Pricing. Margin for Reporting. Here's Why.
Use Markup When:
Use Margin When:
Markup is natural for pricing because you know cost first. Margin is natural for reporting because financial statements are structured around revenue. Neither is better. The problem only arises when one is used for the other's job.
