What Is Markup?
Markup is the amount added to a product's cost to reach its selling price, expressed as a percentage of cost. Cost $60, sell $90 → markup amount $30, markup % 50%. Margin is the flip side: profit as a share of the selling price, not the cost. The two are not interchangeable — the same $30 profit is a 50% markup but only a 33.33% margin.
The Markup Formula
Markup amount = Selling price − Cost
Markup % = (Markup amount ÷ Cost) × 100
Rearranged, the same formula gives the other two directions: Selling price = Cost × (1 + Markup % ÷ 100) and Cost = Selling price ÷ (1 + Markup % ÷ 100). All three are supported by this calculator.
Worked Example
Cost $60, price $90:
- Markup amount = 90 − 60 = $30
- Markup % = (30 ÷ 60) × 100 = 50%
- Margin % = (30 ÷ 90) × 100 = 33.33%
- Cost % of price = (60 ÷ 90) × 100 = 66.67%
The same sale is a 50% markup and a 33.33% margin — the single most common source of pricing errors.
Markup vs Margin
Markup answers: how much am I adding on top of cost? Margin answers: what share of the selling price is profit? Because cost is smaller than price (assuming profit), markup is always the higher percentage. A 100% markup is a 50% margin. A 50% markup is a 33.33% margin.
Convert between them with percentages as decimals:
- Margin = Markup ÷ (1 + Markup)
- Markup = Margin ÷ (1 − Margin)
The Markup ↔ margin mode does both conversions at once.
Product Markup With Direct Costs
The cost you mark up is rarely just the purchase price. Shipping, packaging, and other direct costs land in the same bucket — they were incurred because you sold that unit, and if the selling price does not recover them, they come out of profit. Marking up a $60 purchase price when the true landed cost is $72 produces a price that looks profitable but is not. The Product total cost mode adds those costs before applying the markup.
Discounted Markup
A discount reduces the price the customer pays while the cost stays the same, so effective markup drops by more than the discount itself. On a $60 cost priced at $90 (50% markup), a 10% discount brings the price to $81 — a $21 profit and a 35% effective markup. That is a 15-point drop from a 10% discount. The Discounted markup mode isolates this so you can see the list price, net price, effective markup, and effective margin side by side.
Multiple Products
For a catalogue, the interesting number is the blended markup — total profit ÷ total cost, weighted by how much of each product you sell. That is not the simple average of the individual markups; a low-volume, high-markup product barely moves the blended number while a high-volume, low-markup product dominates it. The Multiple products mode reports both the per-product rows and the blended totals.
Limitations
Markup alone does not determine profitability. A product can carry a high markup and still generate low net profit once operating expenses, marketplace fees, payment processing, advertising, taxes, returns, and overhead are subtracted. This calculator handles the pricing side of the transaction. Use the Margin Calculator when you need the business-level gross, operating, and net margin view.
