The core difference between markup and margin
Markup is the percentage added on top of a product's cost to set its price. Margin is the percentage of the final selling price that represents profit.
$$\text{Markup} = \frac{\text{Selling Price} - \text{Cost}}{\text{Cost}} \times 100$$ $$\text{Margin} = \frac{\text{Selling Price} - \text{Cost}}{\text{Selling Price}} \times 100$$
Because margin divides profit by the higher selling price, margin is always lower than markup on any profitable sale.

Side-by-side comparison table
This lookup reference illustrates how markups translate into realized gross profit margins:
| Cost | Desired Markup | Selling Price | Profit | Realized Margin |
|---|---|---|---|---|
| $50.00 | 25% | $62.50 | $12.50 | 20.0% |
| $50.00 | 33.3% | $66.67 | $16.67 | 25.0% |
| $50.00 | 50% | $75.00 | $25.00 | 33.3% |
| $50.00 | 100% | $100.00 | $50.00 | 50.0% |
| $50.00 | 150% | $125.00 | $75.00 | 60.0% |
| $50.00 | 200% | $150.00 | $100.00 | 66.7% |
The fatal discounting trap
A frequent retail error occurs when a merchant conflates markup with margin before launching a seasonal promotional discount:
- An item costs $100.
- The merchant adds a 50% markup, pricing it at $150. Profit is $50, which equals a 33.3% gross margin.
- During a holiday sale, the merchant advertises a 40% discount off retail price.
- Discounted selling price:
$150 − ($150 × 0.40) = $90. - Because the cost was $100, the business loses $10 on every single sale.
The merchant believed a 50% markup provided enough room for a 40% discount. In reality, the gross margin was only 33.3%, resulting in severe cash drain.
When to use each metric
- Use Markup for quoting and cost-plus contracts: Trade contractors, print shops, and manufacturers calculate materials and direct labor costs, then apply a standard markup (such as cost + 35%) to generate customer quotes.
- Use Margin for financial management: Cash flow projections, budget reviews, and investor reporting require gross margin. Operating expenses are paid from gross margin dollars, not markups.
