Gross Margin
The gross margin shows how much of a company's revenue remains after subtracting the direct costs of the goods or services sold. It is expressed as a percentage and serves as a quick indicator of how profitable a business model is at its core.
A company earns money when it sells something. This income is called revenue. But to be able to sell, it must itself spend money: on materials, on components, on production. If you subtract these direct costs from revenue, what remains is the gross profit. The gross margin states how large this remainder is in relation to revenue, measured in percent. If a company sells goods for 100 euros and pays 40 euros to produce them, the gross margin is 60 percent.
What a high margin reveals about a business model
The gross margin separates two very different types of business. A supermarket buys goods and resells them with a small markup. Its gross margin is often between 20 and 30 percent. A software company, on the other hand, writes its program once and sells it a thousand times over. Every additional copy costs almost nothing. Such companies reach 70 to 90 percent.
For investors, this is an important metric. A high gross margin means: the company has room to breathe. It can invest in research, run advertising, or lower prices without immediately incurring losses. A low margin means that even small price wars become dangerous.
Even more telling is how it develops over time. If the gross margin falls over several quarters, something is off. Perhaps purchase prices have risen. Perhaps the company has to give discounts because competition has intensified. Such shifts show up in the gross margin earlier than in overall profit.
Which costs are included – and which are not
The calculation is simple: revenue minus direct costs, divided by revenue, times a hundred. Direct costs are all expenses that are directly tied to a unit sold. For a carmaker, that’s steel, tires, and wages on the assembly line. For a cloud provider that rents out computing power over the internet, it’s electricity and server costs.
Not included are costs that arise independently of the quantity sold. This includes management salaries, as well as rent for administration, marketing, and research. These items are only deducted later. That’s why the gross margin is always higher than the final profit.
This is exactly where a common misconception lies. A gross margin of 80 percent does not mean the company earns 80 percent. Many technology companies have brilliant gross margins and still post losses because they pour enormous sums into development and advertising. Anyone who wants to see the actual surplus must look at the operating margin or the net profit.
Gross margin in quarterly figures and AI news
Every publicly listed company publishes figures every three months. The gross margin is almost always listed near the top. Analysts compare it with the previous year and with their expectations. If it deviates by a single percentage point, the stock price can react significantly.
In the AI industry, this metric has become especially interesting. Chatbot operators earn money through subscriptions but pay for computing time in the data center for every single answer. This computing time is a direct cost item. The more people use the service, the more it weighs on the gross margin. Classic software scaled almost for free; AI services do not.
That’s why reports often contain sentences like: The provider is working on cheaper computing technology to improve the margin. On the other side stand the chip manufacturers. Whoever supplies the coveted processors for AI can charge high prices and achieves gross margins of over 70 percent. A glance at this number quickly reveals who is really making the money during a boom phase.
