Margin vs Markup

Q: What is the difference between margin and markup?

Both measure profit on a sale, but they use different bases. Margin divides profit by the selling price. Markup divides profit by the cost. The same profit always produces a higher markup percentage than margin percentage.

Q: Which should I use to price my products?

Retailers typically think in margin because it directly tells you what percentage of revenue you keep. Wholesalers and manufacturers often use markup because they start with cost and need to know how much to add. Know which one you are using -- confusing them causes systematic under-pricing.

Q: How do I convert margin to markup?

Markup = Margin / (1 - Margin). Express margin as a decimal first. A 40% margin (0.40) becomes: 0.40 / (1 - 0.40) = 0.40 / 0.60 = 0.667, or 66.7% markup.

Q: How do I convert markup to margin?

Margin = Markup / (1 + Markup). Express markup as a decimal first. A 66.7% markup (0.667) becomes: 0.667 / (1 + 0.667) = 0.667 / 1.667 = 0.40, or 40% margin.

Q: Can margin ever equal 100%?

No. A 100% margin would mean you keep all revenue as profit -- meaning your cost was zero. Margin always stays below 100%. Markup, however, has no ceiling and can exceed 100% easily.

Q: What margin do I need to hit a specific markup?

Use the conversion formula: Margin = Markup / (1 + Markup). For a 100% markup: Margin = 1.0 / 2.0 = 50%. For a 50% markup: Margin = 0.5 / 1.5 = 33.3%.

Margin and markup both measure profit, but they divide by different numbers. Confusing them is one of the most common pricing mistakes in business -- and it compounds at scale.

The key difference

Both margin and markup start with the same profit figure -- revenue minus cost. The difference is what you divide that profit by.

Margin = (Profit / Selling Price) x 100

Markup = (Profit / Cost) x 100

Example: You buy a product for $60 and sell it for $100. Profit = $40. Margin = ($40 / $100) x 100 = 40%. Markup = ($40 / $60) x 100 = 66.7%.

The same profit always produces a higher markup percentage than margin percentage, because cost is always lower than selling price.

The pricing trap

If you target a 40% margin but accidentally apply 40% as a markup, you will chronically underprice. At 40% markup on a $60 cost, the price is only $84 -- and the actual margin is 28.6%, not 40%. This error compounds at scale.

Converting between margin and markup

You can convert between the two using these formulas. Express both as decimals (e.g. 40% = 0.40) before calculating.

Margin = Markup / (1 + Markup)

Markup = Margin / (1 - Margin)

Markup to margin: A 66.7% markup as a decimal is 0.667. Margin = 0.667 / (1 + 0.667) = 0.667 / 1.667 = 40% margin.

Margin to markup: A 40% margin as a decimal is 0.40. Markup = 0.40 / (1 - 0.40) = 0.40 / 0.60 = 66.7% markup.

Margin can never exceed 100% because you cannot keep more revenue than you collect. Markup has no ceiling and can easily exceed 100% -- a 100% markup simply means you doubled the cost.

Here are the most common margin and markup pairs for quick reference. Each row shows the equivalent values.

Margin	Equivalent Markup
10%	11.1%
20%	25%
25%	33.3%
30%	42.9%
33.3%	50%
40%	66.7%
50%	100%
60%	150%

Which one should you use?

Use margin if you think in terms of revenue -- what percentage of each sale do you keep? Retailers, service businesses, and anyone reading financial statements will encounter margin most often. It connects directly to income statements: gross margin, operating margin, and net margin are all margin calculations.

Use markup if you think in terms of cost -- how much do you add on top of what something costs you? Wholesalers, manufacturers, and contractors often use markup because they start with a known cost and need to calculate the selling price.

Neither is wrong. The critical rule is to be consistent and to know which one your number represents. A buyer and seller talking past each other -- one using margin, the other markup -- is a classic source of negotiation confusion.
