How do you calculate Total operation expenses?

Total operating expenses are calculated by summing all costs associated with running a business's core operations, excluding costs related to production. This typically includes selling, general, and administrative expenses (SG&A), such as salaries, rent, utilities, and marketing costs. To calculate, simply add together all these expenses for a specific period, usually a month or a year. The resulting figure provides a clear view of the operating costs incurred during that timeframe.
