"Markup" and "margin" get used interchangeably in everyday conversation, but they're two different calculations that produce two different numbers from the same sale. Confuse them when setting prices, and you'll consistently end up with less profit than you planned for. Here's the distinction, with real numbers, so you never have to guess again.
The one-sentence version
Markup is profit expressed as a percentage of your cost. Margin is profit expressed as a percentage of your selling price. Same sale, same dollar profit — different percentage, because the number on the bottom of the fraction changes.
The core formulas
Buy something for $60 and sell it for $90. Your profit is $30 either way. But:
| Calculation | Result | |
|---|---|---|
| Markup | $30 ÷ $60 | 50% |
| Margin | $30 ÷ $90 | 33.3% |
Same transaction, same profit, two different percentages — because markup divides by the smaller number (cost) and margin divides by the larger number (selling price). Margin will always be a smaller percentage than markup on the same sale, for any positive profit.
The mistake this causes
The expensive version of this confusion: someone wants a 50% margin, but sets their price using a 50% markup instead, thinking the two are the same thing. On a $60 cost:
| Target | Method used | Selling price | Actual margin achieved |
|---|---|---|---|
| 50% margin | Correct: sell price = cost ÷ (1 − margin) | $120.00 | 50% |
| 50% margin (intended) | Mistake: applied 50% markup instead | $90.00 | 33.3% |
That mix-up leaves $30 of intended profit on every single sale, uncollected — not because of a math error, but because "50%" meant two different target prices depending on which formula was actually applied. At volume, that gap compounds into a serious shortfall against a business's real financial targets.
Converting between the two
If you know one, you can always get the other with a quick conversion — no need to start over from cost and price.
(Use markup and margin as decimals in these formulas — e.g., 25% = 0.25 — then multiply the result by 100 to get a percentage back.)

| Markup | Margin |

| 20% | 16.7% |
| 25% | 20.0% |
| 33.3% | 25.0% |
| 50% | 33.3% |
| 75% | 42.9% |
| 100% | 50.0% |
| 150% | 60.0% |
| 200% | 66.7% |

| Margin | Markup |

| 40% | 66.7% |
| 50% | 100.0% |
| 60% | 150.0% |
| 75% | 300.0% |
Notice how the gap between markup and margin widens as the percentages get bigger. At low percentages (10%, 20%) the two numbers are fairly close. Chasing a high margin (60%, 75%) requires a dramatically higher markup — which is exactly where the confusion does the most financial damage if the wrong formula gets used.
Which one should you actually use?
Both are legitimate — they just serve different purposes:
- Markup is usually easier to apply at the point of pricing: take your cost, add a percentage, done. It's common in retail and small-business pricing for exactly that reason.
- Margin is the standard for financial reporting and profitability analysis, because it expresses profit as a share of revenue — the figure that shows up on an income statement and that investors and accountants compare across a business.
Neither is "more correct" — but a business should be explicit about which one it's using, especially anywhere pricing targets, profitability goals, or reports are being communicated between people.
Quick reference: solving for any missing piece
| You know | You want | Formula |
|---|---|---|
| Cost + target markup | Selling price | cost × (1 + markup) |
| Cost + target margin | Selling price | cost ÷ (1 − margin) |
| Cost + selling price | Markup % | (price − cost) ÷ cost × 100 |
| Cost + selling price | Margin % | (price − cost) ÷ price × 100 |
Common mistakes
- Treating a markup percentage and a margin percentage as interchangeable — as shown above, they're never equal (except at 0%), and the gap grows as the percentage grows.
- Dividing by the wrong number. Markup always divides by cost. Margin always divides by selling price. Mixing these up mid-calculation is the single most common source of the error.
- Assuming a "reasonable" markup automatically gives a "reasonable" margin. A 100% markup — doubling the cost, which sounds aggressive — is only a 50% margin, which is a fairly standard target in many retail categories.
- Forgetting that margin has a ceiling markup doesn't. Margin approaches but can never reach 100% (that would mean a cost of $0), while markup is mathematically unbounded.

Frequently asked questions
What's the difference between markup and margin?
Markup is profit expressed as a percentage of your cost. Margin is profit expressed as a percentage of your selling price. The same dollar amount of profit produces a lower margin percentage than markup percentage, because the selling price is always larger than the cost.
Is a 50% markup the same as a 50% margin?
No. A 50% markup on a $60 cost gives a $90 selling price and a 33.3% margin. A 50% margin on that same $60 cost would require a $120 selling price instead. Treating the two as equivalent is one of the most common pricing errors.
How do I convert markup to margin?
Margin = markup ÷ (1 + markup), using markup as a decimal. For example, a 25% markup (0.25) converts to a margin of 0.25 ÷ 1.25 = 20%.
How do I convert margin to markup?
Markup = margin ÷ (1 − margin), using margin as a decimal. For example, a 20% margin (0.20) converts to a markup of 0.20 ÷ 0.80 = 25%.
