Opex (operating expenses)
Running costs that are not part of COGS.
Last reviewedWhat does Opex (operating expenses) mean?
Operating expenses are the costs of running the business that are not in cost of goods sold: selling, general and administrative costs (often called SG&A), and research and development. Gross profit minus operating expenses gives operating profit. In everyday use, "opex" also means day-to-day spending, as opposed to capex.
