What is the Margin Calculator?
Calculate profit margin, markup percentage, and selling price with one tool. Enter cost and selling price to see gross margin, markup, and profit per unit, or work backwards from your target margin to find the right selling price.
The calculator also compares your margin against industry benchmarks for 30+ sectors, including retail, SaaS, manufacturing, restaurants, and e-commerce. It highlights when margin and markup are being confused—a common pricing mistake that can significantly impact profitability.
All calculations run directly in your browser. Your data never leaves your device, and the tool works offline after the first load.

What is the difference between margin and markup?
What is the difference between margin and markup?
Margin is the profit as a percentage of the selling price, while markup is the profit as a percentage of the cost. Example: If you buy a product for $50 and sell it for $100:
- Margin = ((100−50) / $100) × 100 = 50%
- Markup = ((100−50) / $50) × 100 = 100% Our tool automatically detects if you're confusing the two and warns you with a "markup trap" alert to prevent costly mistakes.

What is markup percentage, and how is it different from margin?
What is markup percentage, and how is it different from margin?
Markup % measures profit relative to cost:
- Markup % = ((Selling Price - Cost) / Cost) × 100 Margin % measures profit relative to selling price:
- Margin % = ((Selling Price - Cost) / Selling Price) × 100 Key Difference: Markup is always higher than margin for the same numbers. Example:
- Cost = 50,SellingPrice=100
- Markup = 100%
- Margin = 50% Our tool calculates both automatically, so you never have to guess.

We’re planning to add a batch mode in future updates for comparing multiple products side-by-side.
Why is my margin percentage higher than 100%?
Why is my margin percentage higher than 100%?
A margin cannot exceed 100% because it represents profit as a percentage of the selling price. If you see this, you may have:
- Swapped cost and selling price (enter the higher number as selling price).
- Used markup instead of margin (our tool warns you about this).
- Entered a negative number (check your inputs). The tool validates all inputs and shows an error if the calculation is impossible.
