What is Profit Margin?
Definition
Profit margin measures the percentage of revenue that becomes profit after expenses. It comes in several forms — gross margin, operating margin, and net margin — each measuring profitability at a different stage of the income statement.
Detailed Explanation
There are three main types of profit margins. Gross margin (revenue minus COGS divided by revenue) measures the profitability of core production. Operating margin (operating income divided by revenue) adds selling, general, and administrative expenses. Net margin (net income divided by revenue) includes all expenses, taxes, and interest.
Margin analysis reveals a company's pricing power, cost structure, and operational efficiency. Improving margins over time suggest a company is gaining scale advantages, increasing prices, or cutting costs. Declining margins may indicate rising competition, input cost inflation, or loss of pricing power.
Margins vary enormously by industry. Software companies often achieve gross margins of 70-85% and net margins of 20-35%. Grocery retailers have gross margins of 25-30% and net margins of 1-3%. The key is not the absolute level but the trend and comparison to peers. A retailer with 3% net margin in an industry averaging 2% is outperforming.
Margin expansion is one of the most powerful drivers of stock price appreciation. When a company improves margins while growing revenue, earnings grow faster than revenue (operating leverage). This is why companies transitioning from growth to profitability often see dramatic stock price increases.
Formula
Net Profit Margin = Net Income / Revenue x 100Example
A company with $50B in revenue and $10B in net income has a 20% net profit margin. If the industry average is 15%, this company has superior profitability.
