Markup and margin both describe profit relative to another number. The difference is the denominator: markup compares profit with cost, while margin compares profit with selling price.
Markup starts with cost
Markup equals selling price minus cost, divided by cost. If an item costs $40 and sells for $60, profit is $20 and markup is 50%.
Markup is useful when building a price from a known unit cost, but the selected markup must still cover overhead, payment fees, returns, and other costs not included in the unit figure.
Margin starts with revenue
Margin equals selling price minus cost, divided by selling price. For the same $40 cost and $60 price, the margin is 33.3%.
A 50% markup therefore does not create a 50% margin. Confusing them can produce prices that miss profitability targets.
- Markup % = profit ÷ cost × 100
- Margin % = profit ÷ selling price × 100
- Profit per unit = selling price − unit cost
Define cost consistently
A gross margin calculation commonly uses cost of goods sold, while net profit incorporates broader operating expenses. Label the metric so readers know which costs are included.
For service work, direct labor and subcontractor costs may play the role of unit cost. Owner compensation, nonbillable time, software, insurance, and taxes still need deliberate treatment.
Use the percentage for the decision
Use markup when applying a pricing rule to cost. Use margin when evaluating how much revenue remains after the defined cost. Use break-even analysis when deciding whether total sales can cover fixed expenses.
No single percentage proves that a price is good. Customer value, competition, capacity, demand, cash flow, and risk remain part of the decision.
Markup divides by cost; margin divides by selling price. Always state which costs are included.
Frequently asked questions
Is a 50% markup the same as a 50% margin?
No. A 50% markup on a $40 cost produces a $60 price and a 33.3% margin. Markup divides profit by cost; margin divides profit by selling price.
Which percentage should be used for pricing?
Markup can build a price from cost, while margin evaluates how much revenue remains after the defined cost. Neither replaces a complete profitability and market analysis.
