Markup and margin are two of the most commonly confused terms in business pricing. Both express profit as a percentage, but they use different denominators, which means the same transaction produces two different numbers.
Mixing them up leads to real pricing mistakes. If you intend to achieve a 40% margin but accidentally apply a 40% markup, your actual margin will be 28.6%. At scale, that gap erodes profitability fast.

The Core Difference
Markup = profit as a percentage of cost Margin = profit as a percentage of selling price
Both measure the same profit in pounds (or dollars, euros, etc.) but express it relative to different bases. Because cost is always lower than selling price, markup is always a higher percentage than margin for the same transaction.
They are never equal unless profit is zero.
The Formulas
Markup:
Markup % = (Selling Price - Cost) / Cost x 100
Margin:
Margin % = (Selling Price - Cost) / Selling Price x 100
Converting markup to margin:
Margin % = Markup % / (1 + Markup %)
Converting margin to markup:
Markup % = Margin % / (1 - Margin %)
A Worked Example
You buy a product for £40 and sell it for £60.
- Gross profit: £60 - £40 = £20
- Markup: £20 / £40 = 50%
- Margin: £20 / £60 = 33.3%
Same £20 profit. Two different percentage expressions.
Now imagine you told your buyer "we apply a 50% margin" when you meant a 50% markup. They might calculate £40 x 1.50 = £60 (correct for markup) but if they interpreted it as margin, they would calculate that 50% of £60 is £30, meaning cost = £30 not £40. The confusion compounds quickly across supply chains.
Common Conversion Table
This table shows the relationship between markup and margin for common values:
| Markup % | Margin % |
|---|---|
| 10% | 9.1% |
| 20% | 16.7% |
| 25% | 20.0% |
| 33% | 24.8% |
| 50% | 33.3% |
| 75% | 42.9% |
| 100% | 50.0% |
| 150% | 60.0% |
| 200% | 66.7% |
Notice that even at a 100% markup (you doubled your cost), your margin is only 50%.
When to Use Markup vs Margin
Use markup when:
- Pricing from a cost-up basis (manufacturing, wholesale, retail)
- Communicating with suppliers or procurement teams
- Setting pricing for products where cost is the starting point
Use margin when:
- Analysing profitability against revenue
- Comparing performance across product categories or periods
- Reporting to investors or management (financial statements use margin)
- Setting targets in finance and accounting
Most businesses use both: markup at the pricing stage, margin at the performance analysis stage.
Industry Margin Benchmarks
Gross margin varies enormously by sector. Knowing your benchmark helps you evaluate whether your pricing is competitive or whether you are leaving money on the table.
| Industry | Typical Gross Margin |
|---|---|
| Software / SaaS | 70-90% |
| Consulting / services | 50-70% |
| Retail (fashion) | 40-60% |
| Food service / restaurants | 60-70% (gross) but 5-10% (net) |
| Manufacturing | 20-40% |
| Grocery retail | 20-30% |
| Construction | 15-25% |
These are gross margin figures. Net margin (after operating costs) is typically much lower.
Why Pricing Mistakes Happen
Most markup/margin confusion stems from this scenario: a manager sets a policy of "we aim for a 40% margin on all products." A junior employee interprets this as adding 40% on top of cost, applying a 40% markup instead. The actual margin achieved is 28.6%.
Over a year with £500,000 in revenue, the difference between a 40% margin and a 28.6% margin is £57,000 in profit.
The fix is simple: always clarify which measure you mean, and use both numbers together as a sanity check.
How to Set Your Target Price
If you know your cost and want to achieve a specific margin:
Selling Price = Cost / (1 - Target Margin %)
Example: Cost is £25, target margin is 40%.
Selling Price = £25 / (1 - 0.40) = £25 / 0.60 = £41.67
Check: Margin = (£41.67 - £25) / £41.67 = £16.67 / £41.67 = 40%. Correct.
If you use the markup formula instead:
Selling Price = £25 x 1.40 = £35
That gives a markup of 40%, but a margin of only 28.6%.
The Impact of Increased Costs
One area where margin thinking is critical is when your costs rise. A retailer running on a 33% margin who sees costs rise by 10% needs to increase prices by more than 10% to maintain the same margin.
At cost = £100, selling price = £149.25, margin = 33%. If cost rises to £110, to maintain 33% margin: £110 / 0.67 = £164.18. That is a 10% cost increase requiring a 10% price increase to hold the same margin. In this case they balance, but that is not always the case.
The Markup vs Margin Calculator lets you experiment with different cost and price combinations to understand the impact on both measures.
Summary
Markup and margin both express profit as a percentage, but they are different calculations with different uses.
- Markup: profit divided by cost. Always higher than margin.
- Margin: profit divided by selling price. Always lower than markup.
- Use markup to set prices from cost upward.
- Use margin to measure and compare profitability.
- Never mix the two in the same conversation without clarifying which you mean.
The fastest way to avoid confusion is to always show both numbers together, which is exactly what the calculator does.
