Sum administrative, selling, and general operating expenses and measure OPEX-to-Revenue ratio.
Add up all your operating expenses from salaries to rent to utilities with this free calculator.
Operating expenses (OpEx) are the ongoing costs of running a business that are not directly tied to producing goods or services. They include rent, salaries (non-production), utilities, insurance, marketing, and professional fees.
Operating expenses are subtracted from gross profit to get operating profit.
Operating expenses are day-to-day running costs expensed in the period they occur. Capital expenditure (CapEx) is money spent on long-term assets like equipment and vehicles, which are depreciated over time.
Tracking them separately ensures accurate P&L and balance sheet reporting.
Operating expenses are within your control. Reducing unnecessary OpEx directly improves your operating profit without any change in revenue.
Regular OpEx tracking reveals unnecessary subscriptions, inflating costs, and efficiency opportunities.
Rent and premises costs, salaries and wages (non-production), utilities, internet and phone, software subscriptions, accounting and legal fees, insurance, marketing and advertising, travel, and office supplies.
Categorise each expense to identify where you spend the most.
Your selling prices must cover COGS plus operating expenses to achieve a net profit. Knowing your OpEx is essential for setting prices that make the business profitable at realistic volume levels.
