Margin vs Markup: What's the Difference?
Margin and markup use the same two numbers — cost and price — yet give completely different percentages. Confusing them is one of the most expensive mistakes in pricing. Here is the difference, clearly.
The Core Difference in One Sentence
Markup is profit measured against your cost. Margin is profit measured against your selling price. Same profit, different denominator — which is why the percentages never match.
Margin % = (Profit ÷ Selling Price) × 100
Worked Example (the numbers that prove it)
A product costs $60 and sells for $90. The profit is $30 either way. But:
- Markup = $30 ÷ $60 × 100 = 50%
- Margin = $30 ÷ $90 × 100 = 33.3%
Same product, same $30 profit — but "50%" and "33.3%" describe it depending on which base you use. A business owner who sets a "50% margin" but actually applies a 50% markup is silently under-pricing every single product.
Markup to Margin Conversion Table
| Markup % | Equivalent Margin % |
|---|---|
| 10% | 9.1% |
| 25% | 20.0% |
| 50% | 33.3% |
| 75% | 42.9% |
| 100% | 50.0% |
| 150% | 60.0% |
| 200% | 66.7% |
Markup is always the bigger number. If someone quotes you a "40% margin" but means markup, your real margin is only 28.6% — a gap that wipes out profit at scale.
The Conversion Formulas
Markup % = Margin ÷ (100 − Margin) × 100
Example: a 50% markup → 50 ÷ 150 × 100 = 33.3% margin. A 33.3% margin → 33.3 ÷ 66.7 × 100 = 50% markup. The two always round-trip.
Which Should You Use?
- Use markup when setting a price up from a known cost ("cost plus 50%"). Quick for purchasing and quoting.
- Use margin when analysing profitability, reporting, or comparing products. Margin is what accountants, investors and P&L statements use.
Most pricing errors come from setting prices with markup but reporting and forecasting with margin, without converting between them.
Stop guessing — calculate both
Our calculators show markup and the resulting margin side by side so you never confuse them again.

What is the difference between margin and markup?
+Markup is profit as a percentage of cost; margin is profit as a percentage of selling price. For a $60 cost sold at $90, markup is 50% but margin is 33.3% — same $30 profit, different base.
Is markup or margin higher?
+Markup is always higher than margin for the same product, because cost is always lower than selling price, making the markup denominator smaller.
How do you convert markup to margin?
+Margin % = markup ÷ (100 + markup) × 100. A 50% markup becomes 50 ÷ 150 × 100 = 33.3% margin.
How do you convert margin to markup?
+Markup % = margin ÷ (100 − margin) × 100. A 33.3% margin becomes 33.3 ÷ 66.7 × 100 = 50% markup.
Why does confusing margin and markup lose money?
+If you intend a 50% margin but apply a 50% markup, you only achieve a 33.3% margin — under-pricing every sale and eroding profit across the whole business.
