Field note
Markup vs Margin: The Difference That Changes Your Price
Understand the two percentages, convert between them, and avoid common pricing mistakes.
The useful distinction
Margin is profit as a share of selling price. Markup is profit as a share of cost. A 50% markup does not create a 50% margin: a $10 cost with 50% markup sells for $15, a 33.3% margin.
A simple working method
To price from a target margin, divide cost by one minus the margin. To convert markup to margin, divide markup by one plus markup. These small distinctions prevent underpricing.
Worked example
An item costs 80 and sells for 120. Profit is 40. Markup is 40 divided by 80, or 50%. Margin is 40 divided by 120, or 33.33%. Both describe the same sale from different reference values.
Common mistakes
- Calling a markup percentage a margin
- Dividing profit by cost when reporting margin
- Using a target margin of 100%, which has no finite price
When this number can mislead
A healthy percentage does not guarantee enough profit dollars. Low volume, returns, overhead and long delivery time can still make an offer unattractive, so review both the rate and absolute contribution.
Frequently asked questions
How do I price from a target margin?
Divide cost by one minus the target margin expressed as a decimal.
Why do businesses use markup?
Markup is convenient when you start with a known cost and need a selling price; margin is useful for comparing profitability against sales.
What is the fastest conversion?
Margin equals markup divided by one plus markup. Markup equals margin divided by one minus margin. Convert percentages to decimals first.
Decision checklist
- Name the denominator in every percentage.
- Show profit dollars alongside percentages.
