Margin vs. Markup: The Complete Guide
Published September 1, 2026
Margin and markup describe the same profit against different denominators, which is why they are so easy to swap and so expensive to swap. Margin divides profit by the selling price. Markup divides it by the cost. On the same item, markup is always the larger number — so quoting a markup figure as though it were margin always overstates how profitable you are, and the gap widens as the numbers grow.
This guide gives you both formulas, the conversion in each direction, a reference table you can read off, and the two places the confusion does real damage: pricing to a target, and reporting to anyone who asks how the business is doing.
The short answer
Margin = profit ÷ selling price. Markup = profit ÷ cost. An item costing $60 and selling for $100 has a 40% margin and a 67% markup — the same $40 profit, two denominators. Convert with margin = markup ÷ (1 + markup), or markup = margin ÷ (1 − margin), using decimals.
The two formulas, on one example
Take an item that costs you $60 and sells for $100. The gross profit is $40 either way; only the base changes.
Margin: 40 ÷ 100 = 0.40, or 40%. Markup: 40 ÷ 60 = 0.667, or 66.7%. Margin can never exceed 100%, because profit is a share of the price and the price is the ceiling. Markup has no ceiling at all — a $1 cost sold at $10 is a 900% markup and a 90% margin.
| Figure | Calculation | Result |
|---|---|---|
| Cost | — | $60.00 |
| Selling price | — | $100.00 |
| Gross profit | 100 − 60 | $40.00 |
| Margin | 40 ÷ 100 | 40.0% |
| Markup | 40 ÷ 60 | 66.7% |
Conversion table
Both conversions use decimals: margin = markup ÷ (1 + markup), and markup = margin ÷ (1 − margin). The ladder below is the one worth pinning above a desk, because the two columns diverge faster than intuition expects.
| Markup | Margin | Price on a $100 cost |
|---|---|---|
| 10% | 9.1% | $110.00 |
| 20% | 16.7% | $120.00 |
| 25% | 20.0% | $125.00 |
| 30% | 23.1% | $130.00 |
| 50% | 33.3% | $150.00 |
| 66.7% | 40.0% | $166.70 |
| 100% | 50.0% | $200.00 |
| 150% | 60.0% | $250.00 |
| 300% | 75.0% | $400.00 |
The mistake that costs the most
The expensive version of this confusion is pricing to a target margin by adding the margin to the cost. If you need a 40% margin on a $60 cost and you add 40%, you charge $84 — which is a 28.6% margin, not 40%. You are $16 per unit short of your own target, and nothing in your paperwork flags it.
The correct move is to divide rather than add: cost ÷ (1 − target margin). $60 ÷ 0.60 = $100. Across a catalogue priced by the wrong method, the shortfall compounds quietly — every SKU misses target, and the gap is largest on the items you make the most on.
| Method | Price | Actual margin | Profit per unit |
|---|---|---|---|
| Add 40% to cost (wrong) | $84.00 | 28.6% | $24.00 |
| Divide by (1 − 0.40) (right) | $100.00 | 40.0% | $40.00 |
Which one to use, and when
Neither measure is more correct; they answer different questions. Markup is an instruction — it tells someone what to do to a cost. Margin is a result — it tells you what share of revenue you keep. Most businesses that price well set targets in margin at the strategy level and hand staff a markup rule to apply.
- Use markup for day-to-day quoting, especially with many SKUs or a parts matrix: it converts a cost into a price in one step.
- Use margin for reporting, comparison and targets: it is what appears on a P&L and what industry benchmarks are quoted in.
- Convert once, at the point you set policy — a 40% margin target becomes a 66.7% markup rule — then let staff apply the markup without re-deriving it.
- Label every percentage in writing. "40% margin" and "40% markup" are different prices, and the ambiguity is where the money leaks.
- Remember markup applies to direct cost only: it must be large enough to cover overheads and still leave profit, or rent comes out of what looked like profit.
Gross, net, and what these numbers do not tell you
Both measures here are gross: they count the direct cost of what you sell — materials, packaging, shipping, the labour hours on that specific job — and nothing else. Net margin subtracts everything else too: rent, salaries, marketing, interest, tax.
That gap is where a healthy-looking business fails. A 40% gross margin with overheads consuming 45% of revenue is a loss, and no amount of markup discipline on individual items will show it. Work out what share of revenue your fixed costs consume before deciding whether a markup rule is adequate, and check the volume you need with a break-even calculation rather than assuming.

Frequently asked questions
- What is the difference between margin and markup?
- They compare the same profit to different bases. Margin divides profit by the selling price; markup divides it by the cost. On a $60 item sold for $100, margin is 40% and markup is 66.7%. Markup is always the larger figure.
- How do I convert markup to margin?
- Margin = markup ÷ (1 + markup), in decimals. A 0.60 markup gives 0.60 ÷ 1.60 = 0.375, or 37.5% margin. Going the other way, markup = margin ÷ (1 − margin), so a 40% margin needs a 66.7% markup.
- What markup gives a 50% margin?
- 100%. Doubling the cost is the only markup that leaves exactly half the price as profit, which is why keystone pricing and a 50% margin are the same decision described two ways.
- How do I price a product to hit a target margin?
- Divide the cost by (1 − target margin as a decimal). A $60 cost at a 40% target is 60 ÷ 0.60 = $100. Adding 40% to the cost instead gives $84 and only a 28.6% margin — the single most common pricing error.
- Can margin be more than 100%?
- No. Margin is profit as a share of the price, so it approaches 100% as cost approaches zero but never reaches it. Markup has no ceiling — a $1 cost sold at $10 is a 900% markup.
- Is a 30% markup good?
- It depends entirely on the sector and on what your overheads consume. A 30% markup is a 23.1% gross margin, which is comfortable in grocery distribution and far too thin for a business whose fixed costs eat 30% of revenue. Compare against your own industry and your own cost base.
- Should labour be included in the cost?
- For gross margin, include costs directly tied to producing or delivering the unit, including the labour hours spent on that specific job. Leave out general overheads like rent and admin salaries — those belong in net margin.
