Understanding the financial health of a company is essential for investors. The gross profit margin is among the most important and useful financial metrics that give investors potentially game-changing information about a company's profitability. Let’s dive into what gross profit margin is, why it's important, and how to use it when analyzing a company's performance.
Gross profit margin is a measure of a company's profitability, usually expressed as a percentage. Yes, there is math to be done, but it’s very simple stuff.
First, you look up the company's gross profit, which is revenues minus the cost of goods sold. Most companies report this value near the top of their income statements; others leave this exercise for the reader. Once you have that number and the top-line revenue figure, you divide gross profit by total revenue. That’s all, folks!
What you get is the proportion of each dollar of revenue that the company retains as gross profit. The raw number is a decimal ratio, which you can convert into an easy-to-read percentage. Simply multiply it by 100.
A higher gross profit margin indicates that the company is generating more gross profit for each dollar of revenue, while a lower margin means it's retaining less profit at this stage.
Gross profit margin is a useful financial metric because it reveals a company's ability to generate profit from its core operations. By understanding the gross profit margin, investors can gain insights into a company's cost structure, pricing strategy, and operational efficiency.
A higher gross profit margin suggests that the company is efficiently managing its cost of goods sold. That could be a result of efficient production processes, strategic sourcing, or favorable pricing. On the other hand, a lower margin might indicate systemic trouble or a dramatically different business plan in the same categories.
You should also weigh a company's gross profit margin against those of its competitors. Can this company demand a much higher gross margin than its head-to-head rivals? Cool -- you’re looking at a market leader that can charge a premium price for its products or services.
You also should keep an eye out for large changes over time -- and especially for sudden jumps or drops. Dig deeper to find the underlying reasons for those unexpected shifts. In many cases, you’ll learn something important about the business model this way.
Here’s a simple method for analyzing a company’s gross margins:
Gross profit margin is a useful tool for financial analysis, but it should not be the only instrument in your toolkit. Other financial metrics and operating qualities should also be considered to complete your analysis of a prospective investment. That being said, the gross margin is often a great starting point for a deeper dive.

OK, it’s time to put all this theory to work with a real example. Netflix (NFLX -0.22%), the market-leading video-streaming service, is an interesting case of gross profit margins changing over time. So let's skim the company's gross margins as they evolved from 2019 to 2022. I’m sure there are lessons to be learned here.
In 2019, Netflix reported gross margin in the 37% to 38% range from 2018 to 2021. The economy and Netflix’s target market experienced massive upheaval in this period, and Netflix had to deal with limited content production as the COVID-19 pandemic reared its ugly head.
