What is gross margin?
Gross margin is a financial metric that measures a company's profitability before operating expenses, interest, and taxes are taken into account. It is expressed as a percentage of revenue and represents the portion of revenue that remains after the company pays the direct costs of producing or purchasing the goods sold. These direct costs, also known as cost of goods sold (COGS), include raw materials, direct labor, and other direct costs related to the production of the goods or services sold by the company.
In other words, gross margin is the difference between sales revenue and cost of goods sold. It gives an indication of how efficiently a company uses its materials and labor in the production process. The higher the gross margin, the more efficient the company is considered. However, a high gross margin does not necessarily mean high profitability, as other factors such as operating expenses and interest must also be considered.
How to Calculate a Company's Gross Margin
To calculate a company's gross margin, subtract the cost of goods sold (COGS) from sales revenue. COGS includes the direct costs associated with producing the goods or services the company sells, such as raw materials, direct labor, and other direct costs.
Once you subtract COGS from revenue, you get the gross margin in dollars. To get the gross margin percentage, divide the gross margin in dollars by revenue and multiply by 100. This gives you the gross margin percentage, which indicates how much of the revenue the company keeps after paying direct costs of production.
What is the formula for calculating gross margin?
The formula to calculate gross margin is: Gross Margin = Revenue – Cost of Goods Sold (COGS). To get gross margin as a percentage, divide gross margin in dollars by revenue and multiply by 100.
This formula is used to measure how efficiently a company uses its resources to produce goods or services. The higher the gross margin, the more efficient the company is considered. However, a high gross margin does not necessarily mean high profitability, as other factors such as operating expenses and interest must also be considered.
How to interpret gross margin?
Gross margin is a measure of how efficiently a company uses its resources to produce goods or services. A high gross margin indicates that the company is able to produce goods or services at a relatively low cost compared to the selling price, which may indicate efficient management of resources.
However, a high gross margin does not necessarily mean high profitability. Other factors, such as operating expenses and interest, must also be considered. If these expenses are high, they can eat up a large portion of the gross margin, which can result in low profitability despite a high gross margin.
Here is a numerical example:
- Turnover: €100
- COGS (Cost of Goods Sold): €60
- Operating expenses: €25
- Interest and other expenses: €5
What is the difference between gross margin and net margin?
Gross margin and net margin are two profitability indicators used in financial analysis. Gross margin measures a company's profitability before taking into account operating expenses, interest, and taxes. It is calculated by subtracting the cost of goods sold (COGS) from sales.
Net margin, on the other hand, takes into account all expenses, including operating expenses, interest, and taxes. It is calculated by subtracting all these expenses from sales. Net margin therefore gives a more complete picture of a company's profitability.
How can gross margin help analyze a company's profitability?
Gross margin can help analyze a company's profitability by providing an indication of how efficiently the company is using its resources to produce goods or services. A high gross margin indicates that the company is able to produce goods or services at a relatively low cost compared to the selling price, which may indicate efficient management of resources.
However, gross margin only tells part of the profitability picture. To get a complete picture of profitability, other factors, such as operating expenses, interest, and taxes, must also be considered. These factors can eat up a large portion of the gross margin, which can lead to low profitability despite a high gross margin.
What are the elements to include in the calculation of gross margin?
The items to include in calculating gross margin are revenue and cost of goods sold (COGS). Revenue is the total revenue generated from the sale of the company's goods or services. COGS includes direct costs related to the production of the goods or services sold by the company, such as raw materials, direct labor, and other direct costs.
To calculate gross margin, subtract COGS from revenue. The result is gross margin in dollars. To get gross margin as a percentage, divide gross margin in dollars by revenue and multiply by 100.
Here is a numerical example:
- Turnover: €150
- Cost of goods sold (COGS): €90
How to improve a company's gross margin?
There are several strategies to improve a company's gross margin. One of them is to increase the selling price of the goods or services. This can increase the gross margin if the demand for the goods or services is inelastic, that is, if an increase in the price does not lead to a significant decrease in demand.
Another strategy is to reduce the cost of goods sold (COGS) by improving production efficiency. This can be achieved by optimizing resource utilization, negotiating better prices with suppliers, or improving inventory management.
Is it possible to have a negative gross margin?
Yes, it is possible to have a negative gross margin. This occurs when the cost of goods sold (COGS) is higher than the revenue. This can happen if production costs are very high or if the selling price of the goods or services is too low.
A negative gross margin indicates that the company is losing money on each sale. This can be a sign of financial problems and requires immediate action to cut costs or increase prices.
How is gross margin represented in the income statement?
On the income statement, gross margin is typically presented as a separate line item below revenue. It is calculated by subtracting cost of goods sold (COGS) from revenue.
Gross margin is often expressed as a percentage of sales. This percentage indicates the proportion of sales that remains in the company after paying direct production costs. The higher this percentage, the more efficient the company is considered.
What is the role of gross margin in financial management?
Gross margin plays an important role in financial management because it provides an indication of how efficiently a company is using its resources to produce goods or services. A high gross margin indicates that the company is able to produce goods or services at a relatively low cost compared to the selling price, which may indicate efficient management of resources.
Additionally, gross margin can help identify potential profitability issues. If gross margin is low or negative, it may indicate that production costs are too high or selling prices are too low. In this case, steps should be taken to reduce costs or increase prices.
How to compare gross margin between different companies?
When comparing gross margin between different companies, it is better to use gross margin as a percentage rather than as a dollar amount. Gross margin as a percentage indicates the proportion of sales revenue that remains for the company after paying direct production costs. This allows for a fairer comparison between companies of different sizes.
It is also important to compare companies in the same sector or industry, as gross margin can vary significantly from one sector to another. For example, service companies typically have higher gross margins than manufacturing companies because they have fewer direct costs of production.
What are the factors that can affect gross margin?
There are several factors that can affect gross margin. One of them is the cost of goods sold (COGS), which includes the direct costs associated with producing the goods or services sold by the company. If these costs increase, gross margin may decrease.
Another factor is the selling price of the goods or services. If the selling price decreases, the gross margin may also decrease. Finally, the gross margin can be affected by changes in demand for the company's goods or services. If demand decreases, the company may be forced to reduce its prices, which can reduce the gross margin.
How does gross margin relate to revenue?
Explanation of the graph:
- COGS (light red) : It represents the cost of goods sold, which is a subtraction from sales revenue to obtain the gross margin.
- Gross margin (light green) : This is the portion of revenue that remains after deducting COGS. In this example, gross margin is 40% of total revenue.
Gross margin relates to revenue in that it is calculated by subtracting the cost of goods sold (COGS) from revenue. The result is the gross margin in dollars. To get the gross margin as a percentage, divide the gross margin in dollars by revenue and multiply by 100.
Gross margin percentage indicates the proportion of sales that remains for the company after paying direct production costs. The higher this percentage, the more efficient the company is considered.
What strategies can be used to increase gross margin?
There are several strategies that can be used to increase gross margin. One of them is to increase the selling price of the goods or services. This can increase gross margin if the demand for the goods or services is inelastic, that is, if an increase in price does not result in a significant decrease in demand.
Another strategy is to reduce the cost of goods sold (COGS) by improving production efficiency. This can be achieved by optimizing resource utilization, negotiating better prices with suppliers, or improving inventory management.
7 Corrected Applications on How to Calculate Gross Margin
TechSolutions Application
States :
Lucas is the manager in charge of the workshop "TechSolutions", a small business that sells electronic parts. He is tasked by his director with monitoring the financial results of the workshop. To do this, he must understand how the gross margin is calculated. The electronic parts are purchased for a total annual cost of €20,000 excluding VAT and are sold for a sales price excluding tax (SRP) of €50,000.
Work to do :
1) How to calculate gross margin in amounts?
2) What is the margin rate?
3) What is the markup rate?
4) If the purchase price excluding tax (PA HT) is reduced to €18,000, what would be the impact on the gross margin in amounts?
5) What would be the impact of this reduction in the HT PA on the margin rate and on the brand rate?
Proposed correction:
1) Gross margin in amounts is calculated by deducting the total purchase cost for the year from the sales price excluding taxes.
For TechSolutions, the gross margin will therefore be €50,000 – €20,000 = €30,000.
2) The margin rate is calculated using the formula: Margin rate = ((PV HT – PA HT) ÷ PA HT) x 100.
For TechSolutions, the margin rate is therefore: ((€50,000 – €20,000) ÷ €20,000) x 100 = 150%.
3) The markup rate is calculated using the formula: Markup rate = ((PV HT – PA HT) ÷ PV HT) x 100.
For TechSolutions, the markup rate is therefore: ((€50,000 – €20,000) ÷ €50,000) x 100 = 60%.
4) If the purchase price excluding tax is reduced to €18,000, the gross margin in amounts will then be €50,000 – €18,000 = €32,000.
This represents an increase in gross margin in amounts of €2,000.
5) With a net PA of €18,000, the margin rate would become: ((€50,000 – €18,000) ÷ €18,000) x 100 = 178%.
The markup rate would then be: ((€50,000 – €18,000) ÷ €50,000) x 100 = 64%.
Which means an increase in both the margin rate and the markup rate.

The Delights of the Palace Application
States :
The company "Les Délices du Palais" specializes in the sale of bakery products. For the current year, the company provided the following information regarding one of their flagship products, "Bread Organic":
– The unit purchase cost excluding tax (PA HT) of organic bread is €1,5.
– The resale price excluding tax (PV HT) of organic bread is €3.
– The company sold a total of 5 organic loaves during the year.
The company wants to know the gross margin obtained on the sale of organic bread.
Work to do :
1. Calculate the total purchase cost excluding tax (CTA HT) of organic bread.
2. Calculate the total revenue from the sale excluding tax (RTV HT) of organic bread.
3. Calculate the unit margin on organic bread.
4. Calculate the overall annual margin on the sale of organic bread.
5. Calculate the margin rate and markup rate associated with this product.
Proposed correction:
- The total purchase cost excluding tax (CTA HT) of organic bread is obtained by multiplying the unit purchase cost excluding tax (PA HT) by the total quantity sold.
So, CTA HT = PA HT x Quantity = €1,5 x 5 = €000. - The total revenue from the sale excluding tax (RTV HT) of organic bread is obtained by multiplying the resale price excluding tax (PV HT) by the total quantity sold.
So, RTV HT = PV HT x Quantity = €3 x €5 = €000. - The unit margin is defined as the difference between the selling price excluding tax and the purchase price excluding tax.
Therefore, Unit Margin = PV HT – PA HT = €3 – €1,5 = €1,5. - The overall annual margin on the sale of organic bread is determined by multiplying the unit margin by the total quantity sold.
So, Overall Margin = Unit Margin x Quantity Sold = €1,5 x 5 = €000. - The margin rate is calculated as follows: Margin rate = ((PV HT – PA HT) ÷ PA HT) x 100 = ((3 € – 1,5 €) ÷ 1,5 €) x 100 = 100%.
And the markup rate is established at: Markup rate = ((PV HT – PA HT) ÷ PV HT) x 100
So we have: ((€3 – €1,5) ÷ €3) x 100 = 50%.

Techno-Logic Application
States :
Techno-Logic company specializes in selling computer equipment. Here is some information about one of the products they sell:
– Purchase price excluding tax (PA HT): €125
– Sales price excluding tax (PV HT): €200
– Quantity sold: 50 units
Work to do :
1. What is the unit margin on this product?
2. Calculate the overall margin.
3. What is the product's margin rate?
4. What is the markup rate of this product?
5. What does gross margin represent for a company?
Proposed correction:
- The unit margin is calculated by subtracting the purchase price excluding tax from the sale price excluding tax. This is therefore: PV excluding tax – PA excluding tax = €200 – €125 = €75.
- The overall margin is obtained by multiplying the unit margin by the quantity sold. This gives: Unit margin x quantity sold = €75 x 50 = €3750.
- The margin rate is calculated by dividing the margin by the purchase price excluding tax and multiplying the total by 100. This is therefore: ((PV HT – PA HT) ÷ PA HT) x 100 = ((200 € – 125 €) ÷ 125 €) x 100 = 60%.
- The markup rate is determined by dividing the margin by the sales price excluding tax and multiplying by 100. This is therefore: ((PV HT – PA HT) ÷ PV HT) x 100 = ((€200 – €125) ÷ €200) x 100 = 37,5%.
- Gross margin is the difference between sales revenue and the cost of purchasing the products sold, excluding tax. It therefore provides a measure of the profit generated on the products sold before taking into account other operating costs.
