OpEx

Operating expenses; ongoing costs of running a business.

Operating expenses, commonly known as OpEx, represent the day-to-day costs a business incurs to keep its core operations running. These expenses include items such as rent, utilities, employee salaries, marketing, research and development (R&D), and general administrative costs. Unlike capital expenditures (CapEx), which are investments in long-term assets, OpEx represents immediate costs that are fully expensed in the period they are incurred. Investors analyze OpEx to understand how efficiently a company is managed. By comparing operating expenses to total revenue over time, analysts can determine if a company is scaling efficiently. If revenue is growing faster than operating expenses, the company is demonstrating operating leverage, which typically leads to higher profit margins. While a lower OpEx relative to revenue is generally positive, excessively low operating expenses can sometimes indicate a pitfall. For instance, if a company underfunds its research and development or cuts its marketing budget too deeply to artificially boost short-term profits, it may damage its long-term competitive positioning and future growth prospects.

Company A generates $1,000,000 in revenue. Its cost of goods sold (COGS) is $400,000. It also incurs $200,000 in employee salaries, $50,000 in rent and utilities, and $50,000 in marketing. The operating expenses (OpEx) are calculated by adding these administrative and selling costs together: $200,000 + $50,000 + $50,000 = $300,000.
