A 50% markup and a 50% margin are not the same thing — a routine pricing mistake that comes from expressing the identical profit against two different bases.
How it works
Markup divides profit by cost; margin divides the same profit by price. Because price is always higher than cost on a profitable sale, margin is always the smaller of the two numbers for the same transaction.
Why the mix-up is costly
Pricing to hit a “50% margin” by simply adding 50% to cost actually produces a 33% margin, not 50% — a business that doesn’t distinguish the two can price meaningfully below its actual target without realizing it.
How to use this calculator
- Enter the cost and the selling price.
A worked example
Cost $60, selling price $90 → profit $30. Markup = 30 ÷ 60 = 50%. Margin = 30 ÷ 90 = 33.33% — the same $30 profit, two different percentages depending on which base it’s divided by.
What the terms mean
| Term | Divides profit by | In the example |
|---|---|---|
| Markup | Cost | 50% |
| Margin | Price | 33.33% |
Edge cases worth knowing
Margin can never exceed markup for a profitable sale. Since price is always higher than cost, dividing the same profit by the larger number (price) always gives the smaller percentage.
Targeting “50% margin” by adding 50% to cost is a common, costly mistake — that actually produces a 33% margin, not 50%, exactly the trap this calculator’s own opening line describes.
Frequently asked questions
Which one should I use to set prices?
Margin is what typically matters for profitability targets and financial statements; markup is often more intuitive when pricing directly off cost — both describe the same profit.
Can margin ever be higher than markup?
No, for a profitable sale — margin divides by the larger number (price), so it’s always the smaller percentage of the two.
