Markup vs Margin: The Difference Explained

These two terms get used interchangeably in casual conversation, but they're calculated from different bases and produce different prices for the same target percentage — a mix-up that has quietly underpriced a lot of products.

Why this mix-up causes underpricing

A seller aiming for a "30% profit" who applies a 30% markup instead of a 30% marginends up with an actual margin of about 23%, not 30% — a meaningful gap that compounds across every sale. Since "30% profit" is ambiguous phrasing that could mean either, always be explicit about which calculation you're using, especially when communicating a pricing target to someone else on your team or a supplier.

Frequently Asked Questions

What's the difference between markup and margin?
Markup is profit as a percentage of cost. Margin is profit as a percentage of selling price. Same dollar profit, different denominator — which means the same percentage number means something different depending on which one you're using.
Is a 50% markup the same as a 50% margin?
No. A 50% markup on a $20 cost item gives a $30 price (33% margin). A 50% margin on the same $20 cost item requires a $40 price (50% markup would only be $30). They diverge more as the percentage gets higher.
Which one should I use when pricing?
Margin is usually more useful for business planning since it directly tells you what percentage of revenue is profit. Markup is more common in retail/wholesale conversations. Know which one a supplier or partner means when they quote a percentage.
