Margin vs markup

Margin and markup are two different ways of expressing the same profit dollar amount as a percentage, and confusing them is one of the most common pricing mistakes retailers make. Margin is profit divided by selling price; markup is profit divided by cost. Mixing the two up, even briefly, tends to push prices lower than intended, and the error is easy to make because both terms sound interchangeable in everyday conversation.

How margin vs markup works

Every price a retailer sets carries both a margin and a markup value at the same time, whether or not anyone calculates the second one. Take a product that costs $60 and sells for $100. The profit is $40 in both cases, but expressed differently: markup divides that $40 by the $60 cost, giving 66.7%. Margin divides the same $40 by the $100 selling price, giving 40%. Because the denominators are different, markup will always be a larger percentage than margin for any profitable item. Retailers who set a target margin but calculate it using markup math will consistently price too low and erode profitability without realizing it, sometimes across an entire category.

The confusion tends to surface most often when a buyer negotiates cost with a supplier and then applies a familiar markup percentage out of habit, rather than checking what margin percentage that markup actually produces once the product reaches the customer.

• Markup = profit divided by cost
• Margin = profit divided by selling price
• Cost 60, price 100: markup is 66.7%, margin is 40%
• Markup is always higher than margin on a profitable item

Example

A buyer wants a 50% margin on a jacket that costs $80. Using markup math incorrectly, they might price it at $120 (a 50% markup), which actually delivers only a 33.3% margin ($40 profit over $120 price), not the intended 50%. To hit a true 50% margin, the price needs to be $160, since $80 profit over $160 price equals 50%. That gap between the two numbers, roughly $40 on this single item, is real money left on the table when repeated across an entire catalog of similar products.

Why it matters for retailers

Financial targets are almost always set in margin terms - gross margin percentage is what shows up on the P&L and what investors or lenders ask about - while many buyers and merchandisers still think in markup terms when setting individual prices. That mismatch, repeated across thousands of SKUs, can quietly drag overall profitability below plan even when every individual price felt reasonable at the time it was set, which makes it a hard problem to spot until the quarterly numbers come in. Training the whole pricing team to speak in the same terms removes one of the most common sources of avoidable margin loss.

How Retailgrid helps

Retailgrid's AI workspace calculates margin and markup side by side for every SKU so pricing decisions are never based on the wrong number by accident. The price optimization software lets teams set targets directly in margin terms and see the resulting price, and rules-based pricing can enforce a minimum margin floor automatically across the catalog.
