Margin vs. Markup: The Difference and How to Convert Between Them

Markup is profit as a percentage of cost. Margin is profit as a percentage of the selling price. Buy an item for $40 and sell it for $60, and the $20 profit is a 50% markup ($20 ÷ $40) but only a 33.3% margin ($20 ÷ $60). Both describe the same sale; they just divide by different numbers. Mixing them up is one of the most common pricing mistakes in small businesses, and it always errs in the direction of charging too little.

The formulas

Converting between them:

Use decimals in the conversions (25% = 0.25). The margin calculator and markup calculator solve for any missing value.

Worked example

You buy a jacket wholesale for $40 and sell it for $60.

• Gross profit: $60 − $40 = $20
• Markup: $20 ÷ $40 = 50%
• Margin: $20 ÷ $60 = 33.33%
• Check with the conversion: 0.50 ÷ 1.50 = 0.3333, which matches

Margin is always the smaller number because the price is always larger than the cost when you make a profit.

Pricing to hit a target margin

If you know the margin you need, divide the cost by (1 − margin):

For a 40% margin on a $40 cost: $40 ÷ 0.60 = $66.67.

The tempting shortcut, $40 × 1.40 = $56, applies a 40% markup, and the margin is only $16 ÷ $56 = 28.6%. On $500,000 of annual sales, that difference between a 40% and a 28.6% margin is about $57,000 of gross profit. The price calculator and selling price calculator solve for price from either a markup or a margin.

Why businesses use one or the other

• Markup is convenient on the buying side. A retailer can apply a standard markup to every invoice cost, and keystone pricing (doubling the cost, a 100% markup) is a long-standing retail habit.
• Margin is what appears on financial statements. Gross margin on an income statement is gross profit ÷ revenue, so lenders, investors and accountants think in margin. Budgets and targets are usually set in margin terms.

Pick one convention for your team and label it clearly. “We need 30%” means very different prices depending on which one you mean.

Gross, operating and net margin

The margin in this guide is gross margin: it subtracts only the direct cost of the item. Other margins go further down the income statement:

A product can have a healthy 50% gross margin while the business has a thin net margin once overhead is paid. The profit margin calculator works out all three. To see how many units you must sell to cover overhead, read how to calculate a break-even point.

How discounts eat margin

Discounts come straight out of profit, not out of cost. Take the $66.67 price with a 40% margin and run a 20% off sale:

• Sale price: $66.67 × 0.80 = $53.33
• Profit: $53.33 − $40 = $13.33 (down from $26.67)
• Margin: $13.33 ÷ $53.33 = 25%

Profit per unit is cut in half, so you must sell twice as many units just to earn the same gross profit. Before running a promotion, divide the old profit per unit by the new one to see the sales lift you need.

Markups along a supply chain

Markups compound as goods move from maker to shelf. Suppose a manufacturer’s cost is $20 and it sells to a distributor at a 50% markup ($30). The distributor adds 30% ($39), and the retailer applies keystone pricing, doubling it to $78. Each business earns a respectable margin (33.3%, 23.1% and 50%), yet the shelf price is 3.9 times the original cost. This is why cutting out one layer, by buying direct or selling direct, can change the economics so much.

Services: billing rate vs. labor cost

The same math applies to labor. A contractor pays a technician $35 an hour including payroll taxes and benefits and bills the customer $75 an hour. The markup on labor is $40 ÷ $35 = 114%, but the margin is $40 ÷ $75 = 53%. That 53% still has to cover unbilled hours, vehicles, insurance, software and office staff, so service businesses often need gross margins well above what a retailer would consider healthy.

Common mistakes

1. Using a markup percentage when you meant margin. It underprices every item.
2. Calculating margin on cost. Margin is always divided by price.
3. Leaving out landed costs. Freight, duties, packaging and payment processing fees belong in cost; leaving them out inflates both markup and margin.
4. Forgetting shrink and returns. Damaged, stolen or returned goods reduce the margin you actually realize.
5. Comparing your markup with an industry margin. Industry benchmarks are almost always gross margins.

Quick reference

• Know cost and price? Markup = profit ÷ cost; margin = profit ÷ price.
• Know cost and target margin? Price = cost ÷ (1 − margin).
• Know cost and markup? Price = cost × (1 + markup).
• Know price and margin? Cost = price × (1 − margin).

Sales tax is added on top of the price and does not count toward margin; see how to calculate sales tax.
