What Is a Profit Margin?

“A company can report billions in sales and still struggle to earn a profit. That’s why profit margins matter.”

The profit margin is a financial ratio that measures the percentage of sales a business retains as earnings after deducting expenses. For example, a 25% profit margin indicates that a business retains $0.25 from each dollar of sales. By factoring in business expenses, the profit margin indicates how well a company manages expenses relative to sales, making it a good indicator of a company’s profitability and overall financial health. 

Role of Profit Margins in Business

The profit margin is a widely used profitability metric across businesses, whether they’re billion-dollar enterprises or a taco stand on the sidewalk. The profit margin has essentially become the globally adopted standard measure of a business’s profit-generating capacity and is considered a top-level indicator of its potential. It is one of the first few key figures quoted in the quarterly results reports companies issue.

Business owners, company management, and consultants use it internally to address operational issues and study seasonal patterns and corporate performance. Low profit margin indicates a struggling business that can’t manage its expenses or achieve good sales.

Enterprises operating multiple business divisions, product lines, stores, or facilities that are geographically dispersed may use profit margins to assess each unit’s performance and compare units against one another. 

Role of Profit Margins in Investing

Profit margins help companies to identify issues, raise funds, and attract investors. Profit margins often come into play when a company seeks funding. Large corporations issuing debt to raise capital must disclose how they intend to use the proceeds, which can provide investors with insights into the profit margin they might achieve through cost-cutting, increased sales, or a combination of both. 

Profit margins are a significant consideration for investors. When comparing two or more companies, investors often hone in on their respective profit margins. If a company has a higher profit margin than its peer group, it suggests it is better run and capable of generating greater returns for investors.

Comparing Profit Margins

Profit margins are commonly used to compare a company’s current performance against its past performance and with other companies. This only really works, though, when looking at similar companies operating in the same sector. What is an acceptable or good profit margin in one industry may be low or high in another. There is no magic formula, but as a general rule of thumb, 5% is considered a low margin, 10% an average profit margin, and 20% a high margin.

Businesses like retail and transportation will usually have high turnover and revenue, which can mean overall high profits but low profit margins. Startups or new businesses may have lower profit margins than more established companies because they may have smaller economies of scale, charge lower prices, or need to offer discounts to gain market share.

Industries with the highest profit margins are banking, financial services, and pharmaceuticals. Makers of luxury goods and software-as-a-service (SaaS) companies also tend to consistently generate high profit margins. This is because these industries tend to have lower operational overheads and lower inventory levels, and can gain an advantage by branding or patenting their products or by providing services with little to no competition. 

Mark Notes

Earnings, revenue, and the bottom line are the primary focus of investors when selecting stocks. However, profit margins are another useful tool for comparing companies within an industry and monitoring the overall health of the business.
