Frequently Asked Questions(FAQ)

What is an Operating Expense?

Operating Expense, also known as OPEX, refers to the cost that a company incurs as a result of performing its normal business operations. This doesn’t include costs of goods sold (COGS) but typically includes rent, equipment, inventory costs, marketing, payroll, insurance, and funds allocated toward research and development.

Why are Operating Expenses important for a business?

Operating Expenses provide key insights into how efficiently a company is using its resources. High OPEX can indicate that a company is not managing its resources properly, which might impede profitability. On the other hand, low OPEX might indicate strong management and potential for higher profits.

Where on a financial statement can I find a company’s Operating Expenses?

On a company’s income statement, operating expenses are listed below gross profit and typically classified into several categories such as sales and marketing, general and administrative, and research and development.

How are Operating Expenses different from Capital Expenses?

While Operating Expenses are costs that a company incurs through its normal business operations, Capital Expenses (CAPEX) are funds used by a company to acquire, upgrade, and maintain physical assets. OPEX is regularly incurred and impacts the company’s short-term cash flow, while CAPEX is an investment for the company’s future returns.

Can Operating Expenses be minimized, and how?

Yes, Operating Expenses can be minimized through strategies such as process optimization, automation, outsourcing, cost negotiation, or even moving to a smaller office or less expensive location.

Is the cost of goods sold (COGS) part of Operating Expenses?

No, COGS and Operating Expenses are reported separately in the income statement. COGS is related to the direct cost of producing the goods or services a company sells, whereas Operating Expenses relate to the company’s operations.

How does Operating Expense impact a company’s profitability?

The lower the Operating Expenses, the higher the operating income and consequently, the higher the profitability. Less OPEX leads to more profits retained within the company, which could mean more capacity for growth and expansion.
