Markup Calculator

Markup is the percentage added to the cost of a product to arrive at its selling price. Margin is that same profit expressed as a percentage of the selling price. People mix these up constantly, and it is not a harmless slip. They describe one transaction from two different ends, and the markup number is always the larger of the two.

Markup formula: Selling Price = Cost × (1 + Markup% / 100) Profit = Selling Price − Cost Markup% = (Profit / Cost) × 100

Margin formula: Margin% = (Profit / Selling Price) × 100 Margin% = Markup% / (100 + Markup%) × 100 Markup% = Margin% / (100 − Margin%) × 100

Worked example: A product costs $60 to produce. You apply a 40% markup. Selling Price = $60 × 1.40 = $84 Profit = $84 − $60 = $24 Margin% = ($24 / $84) × 100 = 28.6%

So a 40% markup is only a 28.6% margin. Same $24, same transaction, two very different-looking numbers.

Markup vs. Margin comparison table:

Notice the shape of that table. Margin approaches 100% but can never reach it, because the profit is a slice of a price that always includes the cost. Markup has no ceiling at all.

Industry typical markups:

• Grocery retail: 10 to 30% markup, which is why supermarkets live on volume
• Clothing and apparel: 100 to 300% markup, the origin of the “keystone” rule of doubling cost
• Restaurants: 200 to 500% on food cost, and considerably more on a glass of wine
• Software and subscription products: effectively unlimited, since the cost of one more copy is near zero

Where the confusion costs real money

A shop owner told to hold “a 30% margin” who applies a 30% markup instead is pricing at $1.30 per $1 of cost, when a 30% margin needs $1.43. That is a 13 cent shortfall on every dollar of goods, and it does not announce itself. It shows up months later as a business that is busy and still not making money.

The direction of the error is always the same: markup applied where margin was meant will underprice you. Convert deliberately with the formulas above rather than reaching for the number that sounds right.

Covering your fixed costs

Gross markup on a single unit is not profit. Rent, wages, and insurance come out of the total gross profit across everything you sell, so the question is how many units at this markup cover those costs. If a product returns $24 of gross profit and fixed overhead runs $6,000 a month, 250 units a month is where you break even. Below that, a healthy-looking markup still loses money.
