How to Calculate Markup
Markup is the amount added to the cost of a product to produce its selling price. It is expressed as a percentage of the cost, distinguishing it from gross margin, which is expressed as a percentage of the selling price. Understanding this distinction is essential for anyone setting prices, negotiating with suppliers, or analyzing business profitability.
The Markup Formula
There are two core markup formulas depending on what you are solving for:
Formula 1: Find Selling Price from Cost
Selling Price = Cost × (1 + Markup% ÷ 100)
Or equivalently:
Markup Amount = Cost × Markup% ÷ 100
Selling Price = Cost + Markup Amount
Example: A retailer buys a shirt for $80 and wants a 25% markup.
Formula 2: Find Markup % from Cost and Selling Price
Markup % = (Selling Price − Cost) ÷ Cost × 100
Gross Margin % = (Selling Price − Cost) ÷ Selling Price × 100
Example: A product costs $80 and sells for $120. What is the markup?
Markup vs. Gross Margin: The Key Difference
This is the most commonly confused pair of business metrics. Both describe the same dollar profit, but from different reference points:
| Metric | Formula | Example (Cost $80, Price $100) |
|---|---|---|
| Markup % | Profit ÷ Cost × 100 | $20 ÷ $80 × 100 = 25% |
| Gross Margin % | Profit ÷ Price × 100 | $20 ÷ $100 × 100 = 20% |
Markup is always a larger number than the equivalent gross margin because it divides by the smaller denominator (cost). When someone says "I need 30% margin," they almost always mean gross margin — but if a supplier says "I'm marking this up 30%," that is a markup calculation. Mixing the two up can cost you real money when setting prices.
Markup ↔ Margin Conversion Formulas
Margin % = Markup % ÷ (100 + Markup %) × 100
Markup % = Margin % ÷ (100 − Margin %) × 100
| Markup % | Gross Margin % | Price on $100 Cost |
|---|---|---|
| 10% | 9.09% | $110 |
| 20% | 16.67% | $120 |
| 25% | 20.00% | $125 |
| 33% | 24.81% | $133 |
| 50% | 33.33% | $150 |
| 100% | 50.00% | $200 |
| 200% | 66.67% | $300 |
Retailer Markup Example
A hardware store owner purchases garden tools from a supplier at wholesale prices and needs to determine the appropriate retail price. Here is how a complete markup analysis looks for three products:
| Product | Cost | Markup % | Selling Price | Gross Margin |
|---|---|---|---|---|
| Hammer | $12.00 | 75% | $21.00 | 42.86% |
| Saw | $45.00 | 50% | $67.50 | 33.33% |
| Wheelbarrow | $120.00 | 35% | $162.00 | 25.93% |
The owner uses a higher markup on small, high-velocity items (hammer) and a lower markup on large, expensive items (wheelbarrow) where customers are more price-sensitive. Total blended gross margin on these three items:
Markup and Selling Price Strategy
There are three main pricing strategies, each with a different markup logic:
- Cost-plus pricing: Start with cost, apply a fixed markup. Simple and predictable, but ignores market demand. Used heavily in manufacturing and government contracting.
- Competitive pricing: Set price based on competitors, then work backward to determine if the resulting markup covers your costs. Common in commodity retail and e-commerce.
- Value-based pricing: Price based on what the customer is willing to pay (perceived value), then check if the implied markup is acceptable. Results in the highest markups when executed well.
For small business owners, cost-plus pricing is the most reliable starting point. Know your landed cost (including shipping, duties, and handling), apply a markup that covers your fixed overhead and delivers your target net margin, and adjust based on market feedback.
Frequently Asked Questions
What is the difference between markup and margin?
Markup is the percentage added to cost to arrive at the selling price, calculated as (Profit ÷ Cost) × 100. Margin (gross margin) is the percentage of the selling price that is profit, calculated as (Profit ÷ Selling Price) × 100. A 25% markup on a $80 item gives a $100 selling price and a 20% gross margin. Markup is always a larger number than the equivalent margin because it uses the smaller cost as the denominator. The two figures describe the same dollar profit from different perspectives.
How do I convert markup percentage to gross margin?
Use the formula: Gross Margin % = Markup % ÷ (100 + Markup %) × 100. For a 25% markup: Margin = 25 ÷ (100 + 25) × 100 = 25 ÷ 125 × 100 = 20%. Conversely, to convert margin to markup: Markup % = Margin % ÷ (100 − Margin %) × 100. For a 20% margin: Markup = 20 ÷ (100 − 20) × 100 = 20 ÷ 80 × 100 = 25%.
What markup percentage should I use for my business?
Markup varies widely by industry. Grocery and supermarkets use 10–20% markups on most items. Clothing retailers typically mark up 100–300%. Electronics often carry 20–50% markup. Restaurants mark up food 200–400% (3× to 5× food cost). The correct markup for your business depends on your fixed costs, competition, volume targets, and desired net profit margin. A useful starting point: calculate your break-even markup first, then add the profit margin you need above break-even.
How do I calculate the selling price if I know the cost and desired margin?
If you want a specific gross margin, the formula is: Selling Price = Cost ÷ (1 − Margin%). For a $80 cost with a desired 30% margin: Selling Price = $80 ÷ (1 − 0.30) = $80 ÷ 0.70 = $114.29. This is different from applying a 30% markup to the cost ($80 × 1.30 = $104.00, which yields a 23.1% margin, not 30%). When a buyer says "I need 30% margin," they mean gross margin — use the division formula.
What is keystone pricing in retail?
Keystone pricing is a traditional retail rule of thumb: set the retail price at double the wholesale cost, producing a 50% markup (and a 50% gross margin). Example: a retailer buys a product for $25 and prices it at $50. Keystone is easy to apply and covers most retail overhead when turnover is adequate. However, it is a poor fit for commodity goods where margins are compressed by competition, or for high-cost luxury goods that can support margins above 50%. Many retailers use keystone as a baseline and then adjust by category.
