Markup vs. Margin: Difference, formulas & live converter (2026)
Introduction
Understanding the difference between markup and margin is essential for any business owner who wants to price products correctly and protect their profit. While the two terms are often used interchangeably, they actually measure profitability in different ways, and confusing them can lead to costly pricing mistakes.
This guide will explain both formulas, show you how to convert between them, provide a handy conversion chart, and share industry benchmarks so you can price your products with confidence.
Markup vs. Margin: A quick comparison table
| Markup | Margin |
What it measures | Profit as a % of cost | Profit as a % of selling price |
Denominator (the base) | Cost | Selling price |
Formula | (Price - Cost) / Cost | (Price - Cost) / Price |
$10 cost, $15 price | 50% | 33.3% |
For the same sale | Always the larger % | Always the smaller % |
Both percentages come from the same $5 of profit (the $15 price minus the $10 cost). What changes is the number you divide that $5 by. Markup uses the $10 cost; margin uses the $15 selling price. Since the selling price is the bigger number, margin always works out smaller, which is why the same sale is a 50% markup but a 33.3% margin.
Markup formula
Markup is profit measured against cost:
Markup % = ((Selling Price - Cost) / Cost) × 100
A product that costs $10 and sells for $15 carries $5 of profit, which is a 50% markup ($5/$10). Markup is the number you use when you are building a price up from a cost, because it tells you exactly how much to add. In practice, it is often faster as a multiplier: a 50% markup is 1.5 times cost, and a 100% markup is 2 times cost.
Margin formula
Margin is the same profit measured against the selling price:
Margin % = ((Selling Price - Cost) / Selling Price) × 100
The same $10 product sold for $15 has a 33.3% margin ($5/$15), not 50%. Margin is the number that lands on your profit and loss statement. Markup and margin describe the same $5; they just answer different questions. This is why two people in the same business can quote "40%" and mean different things.
Live markup-to-margin converter
Enter a markup and the converter returns the margin it produces. Enter a target margin and it returns the markup you need, plus the selling price for a cost you type in. It runs both conversions:
Margin = Markup / (1 + Markup) · Markup = Margin / (1 - Margin)
If you would rather not run the formula each time, these are the conversions you will use most:
Markup % | Margin % |
10% | 9.1% |
20% | 16.7% |
25% | 20.0% |
30% | 23.1% |
50% | 33.3% |
75% | 42.9% |
100% | 50.0% |
150% | 60.0% |
200% | 66.7% |
The two numbers drift further apart as they climb. A 25% markup is only 5 points off its margin; a 100% markup is 50 points off.
Industry markup benchmarks
Use these to sanity-check your own pricing, with one caution: The figures below are gross margins and their markup equivalents, not the profit you keep after rent, payroll, and marketing. Grocery is the cleanest example, running a 20–25% gross margin but only about 1–3% net. The numbers come from public-company data compiled in NYU Stern's industry dataset.
Category | Typical gross margin | Equivalent markup | Why it sits there |
Apparel & fashion | ~50–57% | ~100–135% | Keystone (doubling cost) is the norm; fat margins fund heavy seasonal markdowns and brand building. |
Jewelry & specialty | ~40–50%+ | keystone+ | Low price-comparability and high perceived value support premium markups on slow-moving stock |
Furniture & home | ~40–45% | ~65–80% | Slow turnover and bulky, costly logistics are paid for with a fatter margin per sale |
General ecommerce | ~30–50% | ~45–100% | It looks healthy on paper, then acquisition cost, shipping subsidies, and returns quietly eat it |
Consumer electronics | ~teens to low 20% | ~20–35% | Brutal price comparison: many hero items sell near cost as traffic drivers |
Grocery | ~20–25% (1–3% net) | ~25–33% | Razor-thin; the whole model wins on volume and velocity, not margin per item. |
Gross margins reflect public-company medians (NYU Stern/Damodaran and company filings). These are gross margins; single stores usually run several points lower.
Read them as a compass, not a target. Your own costs and customers set your number. If you are tracking margin across a large catalog, inventory software such as Zoho Inventory can calculate it per SKU and flag products that slip below a floor you set, so you are not running these conversions by hand.
Common mistakes
Setting prices in markup but reporting or targeting in margin
This is the costly one, and it only errs in one direction. Since markup is the larger number, treating a markup figure as a margin always means you priced too low, never too high. A "we want 40% margins" instruction typed into a markup field underprices the entire range.
Assuming equal percentages mean equal profit
A 50% markup and a 50% margin are different sales. A 50% markup is a 33.3% margin; a 50% margin needs a 100% markup.
Marking up only the invoice cost
Your markup has to cover more than the supplier's price. Freight, duties, payment fees, and returns are part of your real cost, and a markup set on the invoice alone leaves a thinner margin than it looks.
Pricing below your contribution margin
Contribution margin is what each sale leaves after the variable costs of making it. A price under that and a healthy-looking markup still lose money on every unit.
Frequently Asked Questions
Both describe the same profit on a sale, but against different bases. Markup measures it against cost; margin measures it against the selling price. Since the selling price is always higher than the cost, the margin percentage is always lower than the percentage for the same sale.
Divide the markup by one plus the markup: Margin = Markup / (1 + Markup)
A 50% markup (0.50) becomes 0.50/1.50 = 33.3%
To go the other way, Markup = Margin/(1-Margin).
No. A 50% markup produces a 33.3% margin. A 50% margin needs a 100% markup, which means doubling your cost. Equal percentages almost never describe the same sale.
Subtract the cost from the selling price, divide by the cost, and multiply by 100.
A $10 cost sold for $15 is ($15 - $10)/$10 x 100 = 50%.
