What is Gross Margin?
Gross margin is a financial indicator that shows the percentage of revenue remaining after deducting the direct costs of producing or acquiring a product (COGS - Cost of Goods Sold). It's a fundamental metric for evaluating your business's profitability and pricing strategy efficiency.
For example, if you sell a product for $100 and it costs $60 to produce or acquire, your gross margin is 40%. This percentage is what you have available to cover operating expenses (rent, salaries, marketing) and generate net profits.
Margin vs Markup: The Critical Difference
Margin
Percentage of SELLING PRICE
Margin = (Price - Cost) / Price
Example: Cost $60, Price $100 → Margin = 40%
Markup
Percentage of COST
Markup = (Price - Cost) / Cost
Example: Cost $60, Price $100 → Markup = 66.7%
Confusing margin and markup is one of the most costly mistakes in business. If you want a 40% margin but apply a 40% markup, you'll end up with a real margin of only 28.6%. Our calculator helps you avoid this common error.

Typical Margins by Industry
Retail / E-commerce: 25-50%
Varies significantly by product. Electronics: 15-25%. Apparel: 40-60%. Jewelry: 50-70%.
Software / SaaS: 70-90%
High margins because the marginal cost of each additional unit is nearly zero after initial development.
Restaurants: 60-70%
High gross margin but operating expenses (staff, rent) typically consume much of it, leaving net margins of 3-9%.
Manufacturing: 20-35%
Tighter margins due to raw material costs, labor, and equipment.
How to Use This Calculator
Our calculator offers three modes to adapt to different needs:
- Calculate Margin: Enter cost and selling price to get the resulting margin and markup.
- Price by Margin: Enter cost and desired margin, and we calculate the required selling price.
- Price by Markup: Enter cost and desired markup, and we calculate the resulting price and margin.
You can also add variable expenses (commissions, shipping, payment processing) that are included in the total cost calculation for a more accurate analysis.
