OPEX Operating Expenses

opex meaning

Operating expenses or OPEX refer to the expenditures associated with operating or running a business. They are necessary in order for the company to produce revenue.
They are the muscle that makes things happen. Operating expenses consist of selling, general and administrative expenses (SG&A), research and development, and depreciation.

SG&A expenses are expenditures that are not directly tied to a service or product such as overhead costs.

Selling, general and administrative expenses (SG&A) include expenditures such as sales commissions, management salaries, office supplies, advertising, and accounting and legal fees. The amount of SG&A expenses does not mean much by itself but becomes more meaningful when compared either to total revenues or gross profits.

Generally, the best businesses spend fewer revenue dollars on these activities than their competitors do.

Some companies sell such a valuable product or service that they do not have to advertise much because customers do the selling through word of mouth. This is the best kind of advertising because it is free. If, on the other hand, a business is selling a product or service that is just average and people do not really need it, then a significant amount of resources needs to be spent convincing people to buy it.


COGS The cost of goods sold

The cost of goods sold represents the direct expenditures associated with manufacturing a product. These expenditures include the raw materials, labor, and manufacturing overhead. When reselling a product, the cost of goods sold represents the cost of purchasing it from the manufacturer. When the company provides a service instead of selling a product, the cost of goods sold is replaced with another term – the cost of revenue.

What is important to note is that the cost of goods sold only appears on the income statement when the company is actually “selling” or “reselling” its products or services. What if the company is not able to sell its products? The cost of goods sold does not appear on the income statement because the preparation of financial statements of publicly traded companies has to adhere to GAAP (Generally Accepted Accounting Principles). Under GAAP, companies must follow accrual basis accounting, which means that expenses must be matched with corresponding revenues. If the company is not able to sell its products, it does not have any revenues for the corresponding costs to be matched to, and therefore, the production costs are not expensed through the cost of goods sold on the income statement. Investors can prevent unpleasant surprises by monitoring inventory levels on the balance sheet and comparing them to total assets and revenues. A significant accumulation of products in inventory without a similar increase in revenues may mean that the company is unable to sell it products, and as a result, may need to write down the inventory costs through the income statement as a loss without a corresponding increase in revenues.


The Real Difference between Expenses and Cost of Goods Sold

Operating expenses and cost of goods sold measure various ways in which resources are spent in the process of running an operation.
When an income statement is generated, the COGS and OPEX are shown as separate line items subtracted from total revenue or sales.

Examples of operating expenses include:

  • Utilities
  • Rent
  • Legal costs
  • Insurance costs
  • Payroll
  • Office supplies
  • Sales and marketing

Examples of COGS include:

  • Depreciation of the manufacturing plant
  • Labor directly tied to production
  • Direct materials needed for the production of goods and services
  • Utilities of the facilities tied to production
  • Taxes on the production facilities
