Profit Margin vs Markup: Difference, Formulas and Examples

Profit margin and markup both describe profit, but they measure that profit against different numbers.

Profit margin measures profit as a percentage of the selling price. Markup measures profit as a percentage of cost. That difference is why the two percentages are not the same.

For example, suppose an item costs $50 and sells for $75.

Profit:

$75 − $50 = $25

Markup:

$25 ÷ $50 × 100 = 50%

Profit margin:

$25 ÷ $75 × 100 = 33.33%

The profit is still $25 in both cases. The percentage changes because markup uses cost as the base, while margin uses the selling price.

Profit Margin vs Markup at a Glance

Comparison	Profit Margin	Markup
Based on	Selling price	Cost
Formula	Profit ÷ Selling Price × 100	Profit ÷ Cost × 100
Main purpose	Measure gross profitability	Measure how much was added to cost
Example with $50 cost and $75 price	33.33%	50%
Can normally exceed 100%?	No, with positive cost and revenue	Yes

The easiest way to understand the difference between margin and markup is to remember the base used in each formula.

Margin uses the selling price. Markup uses the original cost.

The Main Difference Between Margin and Markup

Both calculations begin with the same profit amount.

Profit = Selling Price − Cost

The difference comes from what that profit is divided by.

Margin Uses the Selling Price

Profit margin measures the share of the selling price that remains as gross profit.

The formula is:

Profit Margin % = (Selling Price − Cost) ÷ Selling Price × 100

Suppose a product costs $80 and sells for $120.

Profit:

$120 − $80 = $40

Margin:

$40 ÷ $120 × 100 = 33.33%

This means 33.33% of the selling price is gross profit before other business expenses are considered.

Markup Uses Cost

Markup measures profit against the original cost.

The formula is:

Markup % = (Selling Price − Cost) ÷ Cost × 100

Using the same numbers:

Cost = $80
Selling price = $120
Profit = $40

Markup:

$40 ÷ $80 × 100 = 50%

So the same sale has:

• 33.33% margin
• 50% markup

For the same profitable sale with a positive cost, the markup percentage is higher because it uses the smaller base.

Profit Margin Formula With an Example

Suppose an item costs $90 and sells for $150.

First calculate the profit:

$150 − $90 = $60

Now divide the profit by the selling price:

$60 ÷ $150 × 100 = 40%

The profit margin is 40%.

The general formula is:

Profit Margin % = Profit ÷ Selling Price × 100

You can also write it as:

Profit Margin % = (Selling Price − Cost) ÷ Selling Price × 100

For your own numbers, use the Profit Margin Calculator.

Markup Formula With the Same Example

Keep the same example:

• Cost: $90
• Selling price: $150
• Profit: $60

Markup:

$60 ÷ $90 × 100 = 66.67%

So the same transaction produces:

• 40% margin
• 66.67% markup

The markup formula is:

Markup % = Profit ÷ Cost × 100

or:

Markup % = (Selling Price − Cost) ÷ Cost × 100

If you need to calculate markup from cost and selling price, use the Markup Calculator.

Why a 30% Markup Is Not a 30% Margin

A common pricing mistake is assuming a 30% markup produces a 30% margin.

It does not.

Suppose the cost is $100.

If You Add a 30% Markup

Selling price:

$100 × 1.30 = $130

Profit:

$130 − $100 = $30

Margin:

$30 ÷ $130 × 100 = 23.08%

So a 30% markup gives a margin of only 23.08%.

If You Want a 30% Margin

To reach a 30% margin, use:

Selling Price = Cost ÷ (1 − Margin)

Enter the percentage as a decimal:

$100 ÷ (1 − 0.30)

$100 ÷ 0.70 = $142.86

That means:

• 30% markup gives a selling price of $130
• 30% margin requires a selling price of $142.86

The difference is $12.86 per unit.

This is why businesses need to be clear about whether a pricing target refers to markup or margin.

How to Convert Markup to Margin

If you already know the markup percentage, you can convert it to margin without knowing the original cost or selling price.

Use:

Margin = Markup ÷ (1 + Markup)

Suppose the markup is 50%.

Convert 50% to decimal form:

0.50

Now calculate:

0.50 ÷ 1.50 = 0.3333

Convert the result back to a percentage:

33.33% margin

So:

50% markup = 33.33% margin

How to Convert Margin to Markup

To convert margin into markup, use:

Markup = Margin ÷ (1 − Margin)

Suppose the target margin is 40%.

Convert 40% to decimal form:

0.40

Now calculate:

0.40 ÷ 0.60 = 0.6667

Convert that to a percentage:

66.67% markup

So:

40% margin = 66.67% markup

Margin and Markup Conversion Table

Here are some common markup percentages and their equivalent margins.

Markup	Equivalent Margin
10%	9.09%
20%	16.67%
25%	20.00%
33.33%	25.00%
50%	33.33%
75%	42.86%
100%	50.00%
150%	60.00%
200%	66.67%

If you start with a target margin instead, the required markup looks like this:

Target Margin	Required Markup
10%	11.11%
20%	25.00%
25%	33.33%
30%	42.86%
33.33%	50.00%
40%	66.67%
50%	100.00%
60%	150.00%

The higher the target percentage becomes, the larger the gap between margin and markup.

When Should You Use Margin and When Should You Use Markup?

Margin and markup answer different business questions.

Use Margin When You Want to Measure Profitability

Margin helps answer:

How much of the selling price remains as gross profit?

It is useful when reviewing:

• gross profitability
• revenue performance
• pricing performance
• cost changes
• financial reports

Use Markup When You Are Building a Price From Cost

Markup helps answer:

How much should be added above cost?

It is useful when:

• setting a selling price
• applying a pricing rule
• preparing quotes
• comparing price with acquisition cost
• pricing products from known cost

A business may use both measures because they describe different sides of the same sale.

Gross Profit Margin vs Markup

In most pricing discussions, the word “margin” refers to gross profit margin.

Gross profit is:

Gross Profit = Sales − Cost of Goods Sold

Gross profit margin is:

Gross Margin % = Gross Profit ÷ Sales × 100

Markup is:

Markup % = Gross Profit ÷ Cost × 100

The difference is still the denominator.

Gross margin uses sales.

Markup uses cost.

Gross margin should also not be confused with net profit margin.

Net profit margin takes a wider range of business expenses into account, while gross margin focuses mainly on sales and the cost of goods sold.

Why Markup Can Exceed 100% but Margin Usually Cannot

Markup and margin also differ in their possible range.

Suppose:

• Cost = $50
• Selling price = $150
• Profit = $100

Markup:

$100 ÷ $50 × 100 = 200%

Margin:

$100 ÷ $150 × 100 = 66.67%

The markup is 200%, but the margin is only 66.67%.

With a normal sale where both cost and revenue are positive, gross profit remains below the selling price. Because of that, gross margin stays below 100%.

Markup can go above 100% because the profit can be greater than the original cost.

Common Margin and Markup Mix-Ups

Treating 50% Markup as 50% Margin

A 50% markup is not the same as a 50% margin.

For example:

Cost = $100
50% markup = $50

Selling price:

$150

Profit:

$50

Margin:

$50 ÷ $150 × 100 = 33.33%

A true 50% margin would require a selling price of $200.

Adding the Target Margin Directly to Cost

If the target is a 30% margin, multiplying cost by 1.30 gives a 30% markup, not a 30% margin.

For a 30% margin, use:

Selling Price = Cost ÷ 0.70

Using an Incomplete Cost Figure

Markup and margin depend on the cost figure being used.

If important costs are left out, the resulting percentage may not reflect the economics of the sale accurately.

Confusing Gross Margin With Net Margin

Gross margin focuses on sales and cost of goods sold.

Net margin considers a wider range of expenses.

A business can have a healthy gross margin while having a much lower net margin after operating expenses are considered.

A Simple Way to Remember Margin vs Markup

Use these two questions:

Markup: How much did I add to cost?

Margin: How much of the selling price is gross profit?

A simple memory shortcut is:

Markup starts with cost. Margin measures against sales.

If you remember which base each formula uses, the difference becomes much easier to understand.

Frequently Asked Questions

Margin and Markup Are Different Views of the Same Sale

The main difference in profit margin vs markup is the number used as the base.

Markup = Profit ÷ Cost

Margin = Profit ÷ Selling Price

Markup helps show how far the selling price sits above cost.

Margin helps show how much of the selling price remains as gross profit.

Keeping those two ideas separate helps prevent pricing mistakes and makes both calculations easier to understand.

If you also need to determine how much revenue or how many units are required to cover fixed and variable costs, use the Break-Even Calculator.
