What are Operating Expenses (OPEX)? Operating Expenses (often abbreviated as OPEX) are the expenditures a business incurs as a result of its normal, ongoing operational activities, but which are not directly associated with the production of goods or services. These are the costs required to keep the business running day-to-day, separate from the Cost of Goods Sold (COGS). Common categories of operating expenses include Selling, General & Administrative (SG&A) expenses, such as rent, utilities, salaries for administrative and sales staff, marketing, insurance, and office supplies. The term Operating Costs is often used synonymously.

Operating Expenses (OPEX) are important for business owners because they represent the majority of costs involved in running a business, aside from the direct costs of producing goods or services. Effectively managing OPEX is crucial for maintaining profitability, as these expenses are deducted from Gross Profit to determine Operating Income (or operating profit). By tracking and controlling operating expenses, businesses can improve their efficiency, increase their operating profit margin, and enhance their overall financial performance. These figures are key components of the Income Statement.
