Income from Operations

Income from operations is the profit a business earns from its main, ongoing activities during a period. It is calculated by taking revenue and subtracting cost of goods sold and all operating expenses, such as selling, general and administrative costs, research and development, and depreciation. It excludes interest income and expense, gains and losses on investments, other non-operating items and income taxes. The figure is also called operating income or operating profit, and it is often close to, though not always identical with, earnings before interest and taxes.

Because it focuses on the core business and leaves out financing and tax effects, income from operations is one of the most useful measures for comparing how well companies run their businesses. It appears on a multiple-step income statement between gross profit and pre-tax income. The concept and its uses in valuation are also discussed in the entry on operating income.

The basic formula is:

Here $\text{Net sales}$ is revenue after returns, allowances and discounts, $\text{Cost of goods sold}$ is the cost of the products or services delivered, and $\text{Operating expenses}$ covers all other costs of running the business, including selling, administrative expenses, research and development and depreciation and amortization not included in cost of sales.

A home appliance maker reports the following for the year:

• Net sales of $25,000,000 and cost of goods sold of $15,500,000, giving gross profit of $9,500,000.
• Selling expenses of $3,200,000, general and administrative expenses of $2,100,000 and research and development of $1,200,000, a total of $6,500,000.
• Income from operations is therefore $9,500,000 minus $6,500,000, which equals $3,000,000, an operating margin of 12 percent.
• Below the operating line, it has interest expense of $600,000 and a $200,000 gain on sale of investments, giving income before taxes of $2,600,000. After taxes of $546,000, net income is $2,054,000.

The comparison shows that the business generates $3 million from its core activities, but a heavy debt load consumes a fifth of that through interest. A competitor with the same operating income and no debt would report much higher net income.

US GAAP does not strictly define operating income, and the SEC's Regulation S-X does not require it as a separate line, so companies have some discretion over where to draw it. Items such as restructuring charges, impairments and gains on sale of equipment are often included, but practices vary, which makes careful reading of the notes important. Gains and losses from discontinued operations are always shown separately below income from continuing operations.

Under IFRS, there has been no required operating profit line until recently. IFRS 18, Presentation and Disclosure in Financial Statements, issued in April 2024 and effective for periods beginning on or after 1 January 2027, introduces a defined "operating profit" subtotal and new categories of operating, investing and financing income and expenses, with the aim of making results more comparable across companies.

Analysts use income from operations to calculate the operating margin, which shows how much profit each dollar of sales produces before financing and tax. Lenders compare it with interest expense in the interest coverage ratio. Adding back depreciation and amortization gives EBITDA, a common starting point for valuation. Managers track it by business segment to see which divisions earn their keep.

The measure has limitations. Because companies classify items differently, operating income is not always comparable. It ignores the cost of capital, so a company can show strong operating income while destroying value if it uses too much capital to earn it. It is also an accrual measure, so it can differ markedly from operating cash flow when receivables, inventory or payables change sharply. Companies sometimes publish "adjusted" operating income that excludes costs they regard as unusual; these are non-GAAP figures and should be compared with the reported number.
