Markup and the margin it produces
Margin produced by a markup follows margin = markup ÷ (1 + markup). The table shows the standard conversions.
| Markup applied | Margin produced | Price on $100 cost |
|---|---|---|
| 10% | 9.1% | $110 |
| 25% | 20% | $125 |
| 50% | 33.3% | $150 |
| 100% (keystone) | 50% | $200 |
| 150% | 60% | $250 |
| 300% | 75% | $400 |
- Markup and margin converge for small percentages but diverge sharply as prices rise.
- Cost should include all direct costs (freight, duty, packaging), not just the supplier invoice.
- Competitive positioning, perceived value and price elasticity matter as much as arithmetic — cost-plus is a floor, not a strategy.
What is markup?
Markup is a cost-plus pricing convention: the seller adds a fixed percentage of cost on top of cost. It is popular because it is easy to apply across a catalogue — every item gets cost × (1 + markup) — and because purchasing systems record costs directly.
The resulting margin is always lower than the markup percentage, because margin divides the same profit by the (larger) selling price. A 100% markup (doubling cost) produces a 50% margin. Retail trades often speak in 'keystone pricing', a 100% markup, particularly in apparel and giftware.
Cost-plus pricing guarantees cost recovery per unit but ignores demand: it can underprice scarce products and overprice competitive ones. Many businesses use markup as a starting point and adjust for market conditions.
How to use this markup calculator
- Enter the unit cost of the item.
- Enter the markup percentage you want to apply to cost.
- Read the selling price, absolute profit and the gross margin the markup produces.
The formula behind markup pricing
Worked example: cost $50, markup 40%. Price = 50 × 1.40 = $70. Profit = $20. Resulting margin = 20 ÷ 70 × 100 = 28.6%. To find the markup implied by an existing price, compute (price − cost) ÷ cost × 100.
Common mistakes
- Treating markup as margin: a 40% markup is only a 28.6% margin — reporting it as '40% margin' overstates profitability.
- Basing markup on incomplete cost (omitting freight, duty, payment fees).
- Using one blanket markup across categories with very different overhead and return rates.
- Forgetting that discounts come off price, not cost — a 20% sale on keystone pricing cuts margin to 37.5%.
常见问题
What is keystone pricing?
A traditional retail convention of applying a 100% markup — selling at double the cost. It produces a 50% gross margin. Common in apparel and giftware, less so in groceries and electronics where margins are thinner.
What markup do I need for a 30% margin?
Markup = margin ÷ (1 − margin). For a 30% margin: 0.30 ÷ 0.70 = 42.9% markup. A $70 cost item would be priced at $100.
Why is my margin lower than my markup?
Because margin divides profit by the selling price while markup divides it by the smaller cost figure. The same $20 profit on a $50 cost is a 40% markup but only a 28.6% margin at the $70 price.
Should markup include VAT or sales tax?
No. Apply markup to net cost to reach a net selling price, then add any VAT/GST/sales tax separately — tax collected is remitted to the government and is not profit.
Is a higher markup always better?
Not necessarily. Price affects demand: a markup that prices you above the market can reduce total profit even though per-unit profit rises. Markup guarantees cost recovery; it does not guarantee competitiveness.
