Profit margin and markup are closely related, but they answer different pricing questions. Margin measures profit as a percentage of selling price, while markup measures profit as a percentage of cost.
That difference matters because teams often discuss prices, discounts, and targets using the wrong metric. The result can be pricing decisions that look healthy in conversation but miss the real margin goal.
The Simple Difference
Profit margin tells you how much of the sale price you keep as profit after direct cost. Markup tells you how much you added on top of cost to arrive at the selling price.
Because the denominator changes, the percentages are never interchangeable. A 50% markup does not mean a 50% margin.
- Margin = profit / selling price
- Markup = profit / cost
- Markup is always higher than margin for the same item when cost is greater than zero
When Teams Usually Use Margin
Margin is better for business planning because it reflects how much profit remains from each sale. It is the clearer metric when you are tracking profitability, comparing products, or setting gross-margin targets.
- Pricing reviews and profitability reporting
- Comparing product lines or service tiers
- Communicating targets to finance or leadership
When Markup Is Still Useful
Markup is useful when you start from cost and need to calculate a practical selling price. It is common in quoting, wholesale pricing, and procurement-driven workflows where cost is the first known number.
- Building a quote from supplier cost
- Setting retail or resale price from a landed cost
- Explaining pricing logic to teams that think in cost-plus terms
