Operating Expenses and Revenues

Operating revenues and expenses are the income and recognized costs associated with a company’s ordinary business activities. Revenue is the top-line amount earned from providing goods or services. Cost of goods sold and operating expenses are deducted through the income statement to arrive at operating income.

The labels are not simply cash received and cash paid. Revenue can be recognized before collection, expenses can be accrued before payment, and cash spent on inventory or long-lived assets can affect profit in later periods.

Key Takeaways

• Operating revenue, cost of goods sold, and operating expenses occupy different income-statement layers.
• Operating expenses commonly include selling, administration, research, and other support costs not included in COGS.
• Fixed and variable describe cost behavior, not whether a cost belongs in COGS or operating expense.
• Interest and income tax are generally below operating income for non-financial companies, but industry classifications differ.
• Revenue growth does not guarantee operating-profit growth if cost and expense ratios rise.
• Accrual revenue and expense should be reconciled with cash collection, payment, working capital, and capital spending.

Income-Statement Relationship

For a conventional non-financial company:

Combining the equations:

If the statement contains other operating income or expense, impairment, restructuring, or unusual classifications, a simple subtraction may need additional lines.

Worked Example: Revenue to Operating Income

Assume a company reports:

If interest expense is $0.4 million and income tax expense is $0.425 million, pretax income is $1.7 million and net income is $1.275 million. Interest and tax affect bottom-line profit but do not change the $2.1 million operating-income subtotal in this example.

What Is Operating Revenue?

Operating revenue comes from the activities that define the business. Examples include product sales for a manufacturer, subscription fees for a software company, freight charges for a carrier, and interest income for a lender whose ordinary business is lending.

Revenue presentation can include:

• gross sales less returns, discounts, and allowances;
• service or subscription revenue recognized over time;
• contract revenue recognized as performance obligations are satisfied;
• rental or licensing revenue when those are ordinary activities; and
• intersegment revenue that is eliminated in consolidated statements.

Interest or rental income may be operating for one company and non-operating for another. The business model and reporting policy determine the classification.

What Are Operating Expenses?

Operating expenses support ordinary activities but are not included in the cost of units sold under the issuer’s classification. Common examples include:

• selling and marketing;
• general and administrative costs;
• research and development;
• office and support-function salaries;
• professional fees and insurance;
• maintenance of administrative or selling assets;
• depreciation and amortization assigned to operating functions; and
• stock-based compensation assigned to those functions.

Manufacturing labor, materials, factory depreciation, and factory maintenance may enter inventory and cost of goods sold rather than operating-expense lines. Classification by function can therefore hide the nature of a cost inside broader subtotals.

Cost Behavior vs. Statement Classification

Rent may be a fixed operating expense, while raw materials are a variable cost in COGS. A sales commission may be variable and classified as selling expense. “Fixed” is not a synonym for overhead, and “variable” is not a synonym for COGS.

Revenue, Expense, and Cash Flow

Revenue differs from cash collected when receivables, deferred revenue, refunds, or contract assets change. Expense differs from cash paid when payables, accruals, prepayments, inventory, provisions, or capitalized assets change.

For cash conversion analysis, review:

• days sales outstanding and bad-debt trends;
• deferred revenue and customer advances;
• inventory and accounts payable;
• accrued compensation and other liabilities;
• capitalized software, development, and contract costs;
• depreciation and other noncash expenses; and
• capital expenditures and asset disposals.

An improving operating margin can coexist with weaker Operating Cash Flow when receivables or inventory consume cash.

How to Analyze Operating Performance

1. Build a common-size income statement with each line as a percentage of revenue.
2. Separate revenue growth into price, volume, mix, currency, and acquisition effects.
3. Bridge gross margin, operating-expense ratios, and operating margin.
4. Identify reclassifications, capitalization changes, and adjusted exclusions.
5. Normalize for seasonality and changes in consolidation scope.
6. Compare similar business models and accounting policies.
7. Reconcile accrual results to operating cash flow and capital expenditure.

Risks and Common Mistakes

• Treating operating revenue as cash collected from customers.
• Calculating operating expenses as revenue minus net income and COGS, which incorrectly mixes financing, tax, and non-operating items.
• Assuming all variable costs are in COGS or all fixed costs are operating expenses.
• Excluding depreciation from operating expenses without changing the measure to EBITDA or another label.
• Comparing expense ratios without checking capitalization and functional classification.
• Treating interest as non-operating for every industry, including lenders.
• Assuming a lower expense ratio is sustainable without checking deferred maintenance or growth investment.
• Using revenue growth alone as evidence of stronger economics.

Operating revenue and expense analysis depends on the issuer’s reporting framework and business model. This article is educational and is not accounting, audit, tax, valuation, or investment advice.
