Markup and margin describe the relationship between cost and price from two different reference points. Markup expresses profit as a percentage of cost. Margin expresses profit as a percentage of revenue. The two figures are mathematically related but not interchangeable — and conflating them when setting prices produces systematic pricing errors that compress profitability.

Why this metric dictates profitability
A 50% markup does not produce a 50% margin. A business owner who targets a 50% margin but applies a 50% markup will consistently earn 33.3% margin instead — a gap that compounds across every sale. At $1,000,000 in annual revenue, the difference between 33.3% and 50% gross margin is $166,700 in foregone gross profit per year.
Equation and data inputs
Markup (profit as percentage of cost):
\text{Markup} = \frac{\text{Price} - \text{Cost}}{\text{Cost}} \times 100
Gross margin (profit as percentage of revenue):
\text{Margin} = \frac{\text{Price} - \text{Cost}}{\text{Price}} \times 100
Conversion: markup to margin:
\text{Margin} = \frac{\text{Markup}}{1 + \text{Markup}}
Conversion: margin to markup:
\text{Markup} = \frac{\text{Margin}}{1 - \text{Margin}}
Setting price from a target margin:
\text{Price} = \frac{\text{Cost}}{1 - \text{Target Margin}}
Benchmark ranges
| Target gross margin | Required markup | Example: $40 cost → Price |
|---|---|---|
| 20% | 25.0% | $50.00 |
| 30% | 42.9% | $57.14 |
| 40% | 66.7% | $66.67 |
| 50% | 100.0% | $80.00 |
| 60% | 150.0% | $100.00 |
| 70% | 233.3% | $133.33 |
Common variable mistakes
Applying a target margin percentage as a markup percentage. This is the single most common pricing error. A product that must deliver a 40% margin priced using a 40% markup over cost earns 28.6% margin instead.
Using inconsistent denominators across departments. When purchasing teams quote costs with markup included and the finance team tracks margin, the two figures represent different things. Aligning the organization on a single convention — markup or margin — and converting where necessary prevents systematic miscommunication.
Ignoring the effect of discounts on margin. A 10% discount on a product with a 40% margin reduces gross margin to approximately 33.3% — nearly a 7-point drop. At a 20% margin, a 10% discount produces a 12.5% margin — a 7.5-point drop that can turn a profitable SKU into a loss.
