Operating profit is the income a company earns from its core business during a period, after subtracting the costs of running that business but before interest, taxes and income from investments or other side activities. It answers a narrow question: did selling the company’s goods or services, at the prices it charged and the costs it incurred, make money? When core expenses exceed core income, the result is an operating loss.

The figure is also called operating income, and it appears on the income statement, usually as the line between gross profit and the interest and tax lines.

How operating profit is calculated

The formula

The standard operating profit formula works down from revenue in two steps:

Gross profit = Revenue − Cost of goods sold (COGS)

Operating profit = Gross profit − Operating expenses − Depreciation − Amortization

Combined into one operating profit equation:

Operating profit = Revenue − COGS − Operating expenses − Depreciation − Amortization

Many income statements do not show depreciation and amortization as separate lines. They are often folded into COGS (for factory equipment) or into selling, general and administrative expenses (for office assets). In that case, subtracting COGS and total operating expenses from revenue already gives operating profit, and deducting depreciation again would count it twice. Read how the company presents its costs before applying the formula line by line.

What counts as an operating expense

Operating expenses are the costs required to keep the business running that are not part of producing the goods themselves. Typical examples:

• Salaries and wages for staff outside production, including executive pay
• Rent, utilities and insurance
• Marketing and advertising
• Research and development
• Office supplies and general administrative costs

Wages of workers who make the product usually sit in cost of goods sold instead. Either way, salaries reduce operating profit. The only difference is whether they are deducted above or below the gross profit line.

Gross profit does not include operating expenses. It subtracts only the direct costs of producing what was sold, which is why gross profit is always larger than operating profit for the same company, unless operating expenses are zero.

Depreciation and amortization are included because they spread the cost of assets the business uses (machinery, buildings, software, patents) over their useful lives. Those assets are consumed by operations, so their cost belongs in an operating measure even though no cash leaves the company when depreciation is recorded.

What operating profit excludes

Anything that does not come from the core business sits below the operating profit line:

A few rules here are frequently misunderstood. Selling a long-term asset such as a warehouse or a production line is not operating revenue, because disposing of equipment is not what the business exists to do. Items made for sale as part of the core business are the exception: a homebuilder’s houses are inventory, not fixed assets, so their sale is revenue.

Income from a partial stake in another company is also excluded, even when that other company operates in the same industry. The earnings come from owning shares, not from running operations.

Interest on debt is left out even when the borrowing funds day-to-day operations. Operating profit deliberately ignores how the business is financed.

Classification of unusual items such as legal settlements, restructuring costs or inventory write-downs varies. Some companies report them within operating expenses; others show them separately. Comparing two companies therefore means checking where each places these items.

Operating profit example

Hypothetical example. A furniture maker reports the following for one year:

• Revenue: $2,000,000
• COGS (wood, hardware, factory wages): $1,100,000
• Selling, general and administrative expenses: $450,000
• Depreciation on equipment (reported separately): $80,000
• Amortization of a design patent (reported separately): $20,000
• Interest on a bank loan: $60,000
• Gain on selling an old delivery truck: $15,000

Gross profit is $2,000,000 − $1,100,000 = $900,000. Operating profit is $900,000 − $450,000 − $80,000 − $20,000 = $350,000.

The $60,000 of interest and the $15,000 gain on the truck do not enter this figure. They appear further down the income statement on the way to pretax income and net income.

A real company. Walmart reported total revenues (net sales plus membership and other income) of $648.12 billion for fiscal year 2024. Cost of sales was $490.14 billion, and operating, selling, general and administrative expenses were $130.97 billion. Subtracting both from revenue gives $27.01 billion, which matches the operating income Walmart reported for that year. Walmart’s statement does not break out depreciation separately, so the two expense lines cover it.

Operating profit margin

Operating profit in dollars is hard to compare across companies of different sizes. The operating profit margin (sometimes called the operating profit ratio) scales it to revenue:

Operating profit margin = Operating profit ÷ Revenue × 100

In the furniture example, $350,000 ÷ $2,000,000 = 17.5%. For Walmart’s fiscal 2024 figures, $27.01 billion ÷ $648.12 billion is about 4.2%. The margin shows how many cents of operating profit each dollar of revenue produced. Low-margin, high-volume retail and high-margin software businesses can both be healthy, so margins are most informative when compared within an industry or across a company’s own periods.

How operating profit is used

Because it strips out financing, taxes and investment activity, operating profit isolates how well management runs the business itself. Two companies with identical operations but different debt levels or tax situations will show similar operating profit and very different net income.

Common uses include:

• Trend analysis. Rising revenue is a good sign only if costs do not rise faster. Operating profit growing alongside revenue shows the company is converting extra sales into earnings; operating profit falling while revenue climbs points to cost pressure or discounting.
• Peer comparison. Operating margin lets analysts compare competitors with different capital structures.
• Segment analysis. Large companies often report operating income by division. Divisional operating income is calculated the same way, using the revenue and costs attributed to that segment, though shared corporate costs may be allocated or left unallocated depending on the company.
• Valuation and lending. Operating profit feeds into ratios such as interest coverage (operating profit ÷ interest expense), which lenders use to judge whether a company can service its debt.

Limitations of operating profit

Operating profit is not cash. It includes non-cash charges like depreciation and is based on accrual accounting, so revenue may be booked before customers pay. Free cash flow is the better measure of cash the business actually generates.

It also ignores obligations the company must meet. A firm with heavy debt can show a solid operating profit while interest payments push it into a net loss. For that reason, companies sometimes highlight operating profit in their communications because it can look stronger than the bottom line. Positive operating profit describes the period just ended; it does not guarantee future profitability.

Finally, accounting choices affect the figure. Depreciation methods, how costs are split between COGS and operating expenses, and where unusual items are placed all change the result, which limits comparisons between companies that make different choices.

Operating profit vs. other profit measures

Operating profit vs. gross profit

Gross profit subtracts only the direct costs of producing goods sold. Operating profit goes further and also deducts selling, administrative and other operating costs plus depreciation and amortization. Gross profit shows the economics of the product; operating profit shows the economics of the whole business.

Operating profit vs. EBIT

Operating profit is often used as a synonym for earnings before interest and taxes (EBIT), and the two are equal when a company has no non-operating income or expenses. They diverge when there are items such as investment income or a gain on an asset sale, because EBIT is frequently calculated from net income by adding back interest and taxes, which leaves those non-operating items inside it. Operating profit excludes them.

Operating profit vs. EBITDA

EBITDA adds depreciation and amortization back to operating profit:

EBITDA = Operating profit + Depreciation + Amortization

It is used as a rough proxy for operating cash generation. Operating profit, by keeping those charges in, recognizes that equipment and intangible assets wear out and must eventually be replaced.

Operating profit vs. net profit

Net profit, the bottom line, starts from operating profit and then adds non-operating income (investment returns, gains on asset sales) and subtracts non-operating costs (interest, taxes, unusual charges). Everything below the operating profit line reflects financing, taxation and activities outside the core business, which is why net profit can move sharply in a year when operations barely changed.

FAQs

The Bottom Line

Operating profit matters most to investors, analysts and lenders who want to judge how well a company runs its core business, apart from debt and taxes. It works best for tracking trends and comparing margins within an industry. Check how each company classifies depreciation and unusual items, and pair the figure with free cash flow and net income, since solid operating profit can still coexist with weak cash generation or a net loss.
