Online tools > Gross margin calculator


Whether you're a small start-up or a large multinational corporation, understanding gross margin means having a reliable guide to moving forward in your commercial activities. This calculation helps companies in all sectors to understand the profitability of their products or services. By analyzing the percentage of net revenue you get to keep per sale after the cost of goods sold (COGS) is deducted, the gross margin provides a clear vision of opportunities and potential profits. Gross margin is much more than a simple mathematical formula: it's a strategic tool that informs, guides, and inspires effective, well-thought-out management!


Our gross margin calculation tool allows you to calculate the gross margin that you’ll be able to recover from the sale of a product or service in just one click. The formula for calculating gross margin is quite simple and often used in finance and accounting. Gross margin represents the difference between the sales revenue and the COGS, divided by the sales price, all multiplied by 100.

💵 Sales Price ($)Price at which the product will be sold
🔨 Purchase / Production Cost ($)Initial cost of purchasing or manufacturing the product
📊 Gross Margin (%)Percentage indicating the profitability of the product or service after deducting the cost of purchase or production


The formula takes the following data into account:

  • Sales price: the price at which a product or service is sold to the customer.
  • Cost of goods sold (COGS): the total cost of producing a good or providing a service. This includes direct costs, such as raw materials and labor, and the purchase price of the product from the supplier, but it does not include indirect costs such as overhead expenses.
  • Difference between the sales price and COGS: subtracting the COGS from the sales price gives the gross profit on the product or service.
  • Division by sales price: the gross profit is then divided by the sales price to obtain a ratio.
  • Multiplication by 100: expressing the gross margin as a percentage makes for a more intuitive interpretation and facilitates comparison with other indicators.

Gross margin is a performance indicator that must always be optimized to ensure that your company's sales are always profitable. But what are the key points to monitor in order to constantly improve your breakeven point?

  • Cost analysis: cost analysis can reveal opportunities for savings. By reducing costs without compromising quality, you can increase margins.
  • Pricing strategy: setting prices strategically can help you maximize your margin, while offering attractive deals to your target market.
  • Supplier management: negotiating with suppliers to obtain better prices on raw materials can reduce production costs.
  • Quality improvement: offering a quality product or service can justify a higher selling price, thus increasing profit without increasing costs.
  • Process optimization: efficiency in production and distribution can reduce costs and increase profit. Think automation!
  • Monitor your market: knowing your customers' needs and expectations will help you position your products to maximize perceived value and, consequently, your selling price. Keep an eye on your conversion rate too: a high rate means you're effectively converting prospects into customers, which can boost your margins without necessarily increasing sales volume.


What is gross margin?

Gross margin is a financial indicator that measures the profitability of a product or service. This metric is often used by companies to assess the profitability of their products or services, and to make decisions concerning pricing, production, and overall business strategy.

What gross margin do you need to be profitable?

The type of product or service, the sector of activity, the cost structure and the competition in the market are all factors that influence gross margin. In general, a gross margin of 30% is considered a good rate. However, there’s no universal rate that guarantees profitability in all cases.

What’s a good gross margin?

A good gross margin is one that supports the company's financial health, aligns with its strategy, and enables continued growth and innovation. To better understand the subtleties of gross margins, you can work with finance or industry professionals to analyze the specifics of your business and determine the optimal rate.

What are the consequences of an unsuitable gross margin?

If the gross margin is too low, this can lead to a reduction in profits, as the company doesn't earn enough on each sale. With a low margin, the company may find it difficult to invest in research, development or marketing, thus limiting its competitiveness. A low gross margin can expose the company to financial risks in the event of market fluctuations or cost increases. To maintain a low margin, the company may have to reduce the quality of its products or services.

On the other hand, a gross margin that’s too high can mean higher prices for consumers, which can reduce demand. If competitors offer similar products at lower prices, a high markup can leave the company vulnerable to losing market share. A high margin can be perceived as greed, which can damage the company's reputation with consumers.
