Definition
Operating Expenses (OPEX) represent the costs a business incurs through its normal business operations. These expenditures are not directly tied to the production of a specific product or service but are necessary for the overall functioning of the company. Also known as selling, general, and administrative (SG&A) expenses, OPEX covers a wide range of costs from rent and utilities to employee salaries and marketing.
OPEX is a primary component of a company's income statement, or profit and loss statement (P&L). It is subtracted from gross profit to determine the operating income, which reflects the company's ability to generate profit from its core business activities. Consistent monitoring and analysis of operating expenses are fundamental to financial planning and budgeting processes.
It is important to distinguish operating expenses from Capital Expenditures (CAPEX), which are funds used to acquire, upgrade, and maintain long-term physical assets like property, buildings, or equipment. While OPEX appears on the P&L as it is incurred, CAPEX is capitalized on the balance sheet and depreciated over time.
