Learn About Operating Income and Profit Margin
Analyzing an Income Statement
Operating income, also called operating profit, represents the total pre-tax profit a business has generated from its operations. Investors and analysts often use operating profit information to assess the desirability of companies as investment candidates. For a business like Papa John's Pizza, for example, it represents the pre-tax profit the company generates from selling pizzas.
The operating income shows, in terms of dollars, what remains for the owners after deducting all of the expenses related to producing the pizzas and operating the business.
The profit margin represents a view, in percentage terms, of the operating income left over after all expenses, making it easier to compare to the profit margin percentage of other, similar companies.
Gauging a Company's Operational Performance
Operating income can be used to gauge the general health of a company's core business or businesses. All else being equal, profits count as of the most important figures to review when you consider buying an ownership stake in a business through the purchase of common stock, or when deciding whether to lend your money to a business through an investment in its corporate bonds.
Unless a firm has a lot of assets it can sell, any money that it pays out to shareholders as dividends must be generated by selling a product or service. If a company experiences declining operating income, this means it has less money for owners, for expansion, debt reduction, or anything else management hopes to achieve.
Lenders and shareholders tend to watch operating profit closely. This can present certain challenges, as some businesses have operating income that fluctuates wildly with economic conditions.
These types of firms are known as cyclical companies. They consist of businesses such as steel mills, aluminum manufacturers, automobile manufacturers, heavy equipment manufacturers, hotels and resorts, home builders, and many luxury item manufacturers, such as fine jewelry companies.
These enterprises may still make a good deal of money, but they won't have a smooth, upward trend in operating income because the business will likely contract during recessions and depressions.
When gauging the value of cyclical companies, a single year of operating profit in isolation won't tell you what you need to know, so work with at least two or three years' worth of historical data before drawing your conclusions.
What's Operating Income?
Gross profit results from subtracting a company's cost of goods from its gross revenue. Below gross profit on the income statement, you'll find the firm's operating expenses. These include items such as compensation-related expenses, sales and marketing costs, and miscellaneous office expenses like utilities and office supplies.
Use the following formula to calculate operating income with inputs from the income statement:
Calculating the Operating Margin
To calculate the operating margin, divide your operating income result from above by total revenue.
Operating Income / Sales = Operating Margin
The percentage result that qualifies as a good operating margin depends on the industry. However, you can also get a frame of reference by comparing a company's operating profit margin to the S&P 500, which represents the average, or market rate of return.
If your target company's profit margin exceeds the S&P 500's return, you have found a company that is beating the market.
Interpreting the Results
Companies review their operating margin, or operating profit margin, as a measurement of management efficiency. The profit margin calculation provides a result that helps compare the quality of a company’s financial activity to its competitors.
A business with a higher operating margin than other firms in its industry generally has better performance, as long as the gains didn't come from taking on large amounts of debt or by taking speculative risks with shareholders' money.
The most common reason companies experience high operating margins relative to their competitors stems from a low-cost operating model, where the company has found a way to deliver merchandise or services to customers at much cheaper prices than its competitors and still make a profit.
A classic example is Wal-Mart, which can get everything from toothpaste to socks into its stores at far lower prices than the competition due to the efficiency of its warehouse distribution system.
