Profit Margin vs. Markup: What Is the Difference?
By Markets & Investing DeskUpdated Nov 10, 2026
Key takeaways
- Both terms use the same two inputs: selling price and cost of goods sold (COGS).
- Margin = (price − cost) ÷ price. Markup = (price − cost) ÷ cost.
- A 30% margin and a 30% markup produce different prices, and confusing them underprices a product.
- Margin can never reach 100%. Markup has no upper limit.
- Neither figure accounts for overhead, so a healthy markup can still leave a business unprofitable.
Profit margin and markup measure the same dollar amount, the gap between a product’s selling price and its cost, against different bases. Profit margin divides that gap by the selling price (revenue). Markup divides it by the cost. A product that sells for $100 and costs $70 earns $30 either way, which is a 30% margin but a 42.9% markup. Because the bases differ, the markup percentage on any profitable sale is always higher than the margin percentage.
The terms behind both formulas
Three accounting terms carry the calculation:
- Revenue is the gross amount a business receives from selling its goods or services.
- Cost of goods sold is what it spends to produce or provide those goods or services, such as materials, components and direct labor.
- Gross profit is the revenue left after subtracting COGS.
When people say “margin” in a pricing discussion, they usually mean gross margin: gross profit as a share of revenue. Profit itself is a broader idea, and the difference between revenue and profit matters once operating expenses and taxes enter the picture.
Worked example
Take the product above: selling price $100, cost $70.
- Gross profit: $100 − $70 = $30
- Margin: $30 ÷ $100 = 30%
- Markup: $30 ÷ $70 = 42.9%
The dollar profit is identical. Only the denominator changes. Margin answers “what share of each sales dollar do I keep?” Markup answers “how much did I add on top of what I paid?”
Converting between margin and markup
With margin and markup written as decimals, each converts directly to the other:
- Markup = margin ÷ (1 − margin)
- Margin = markup ÷ (1 + markup)
Some common pairs:
| Margin | Equivalent markup |
|---|---|
| 20% | 25% |
| 28.6% | 40% |
| 30% | 42.9% |
| 33.3% | 50% |
| 50% | 100% |
| 75% | 300% |
A 100% markup (doubling the cost) is only a 50% margin. As margin approaches 100%, markup rises without limit, because the cost becomes a smaller and smaller share of the price.
Setting a price from a target
The two formulas lead to different pricing methods:
- From a target markup: price = cost × (1 + markup)
- From a target margin: price = cost ÷ (1 − margin)
The cost/(1 − margin) formula is the one to use when a business plans around margins. Here is the error it prevents. Suppose a seller wants a 30% margin on a $70 item but applies a 30% markup instead: $70 × 1.30 = $91. The gross profit is $21, and $21 ÷ $91 is only a 23.1% margin. The correct price for a 30% margin is $70 ÷ 0.70 = $100.
The same logic works in reverse for finding cost of sales. If a business knows its sales and its markup on cost, cost of sales = sales ÷ (1 + markup). With $100,000 of sales at a 25% markup, cost of sales is $80,000.
How the difference shapes pricing strategy
Markup is the natural tool at the product level. A retailer or contractor knows what an item or job costs and adds a percentage to reach a price. That makes markup quick to apply across many items.
Margin is the natural tool for planning and comparison. Because it is measured against revenue, it lines up with the income statement and can be calculated for a single product, a product line, a division or an entire company. Lenders, investors and managers compare margins, not markups.
Trouble starts when the two are mixed: a pricing team using markups while the budget assumes margins will consistently fall short of the plan by the gap shown in the conversion table above.
What the formulas leave out
Several factors change how useful either number is:
- Direct costs move. A direct cost is anything a product cannot exist without, like an ingredient in a restaurant dish. These costs can be fixed or variable and can rise with inflation. A fixed markup on an outdated cost quietly erodes margin.
- Overhead is excluded. Rent, salaries and marketing sit outside COGS. Gross margin and markup say nothing about whether those are covered; net margin does.
- The market sets limits. Pricing depends on internal factors such as COGS and external ones the seller has little control over: competitors’ prices, demand and supply, and inflation. A price far above competitors’ can cost sales and market share over time; one set too low gives away profit.
- Services are harder to cost. For services, the “cost” is mostly labor time, so markup is often applied to an hourly labor cost. The margin and markup math is the same, but the result is only as accurate as the time estimate.
FAQs
Is contribution margin the same as markup or profit margin?
No. Contribution margin is the selling price minus variable costs only, often expressed per unit or as a percentage of price. Gross margin subtracts all of COGS, which can include some fixed production costs. Markup uses the same profit figure as gross margin but divides by cost instead of price.
What is a good markup?
There is no universal figure. A good markup is one that, after converting to margin, covers overhead and leaves a profit at a price customers will pay. Low-cost, high-volume goods can work with thin markups, while products with high overhead or slow sales need larger ones.
The Bottom Line
Anyone who sets prices or reviews budgets needs to know which base a percentage uses, because a 30% markup on a $70 item yields only a 23.1% margin. Price from a target margin with cost divided by one minus the margin, and keep costs current. Since neither figure covers rent, salaries or marketing, check net margin before calling a product profitable.
