How to Calculate Operating Costs for Your Business

Operating costs represent the routine expenses a business incurs from its normal day-to-day activities. These are the expenditures required to keep the business running and generate revenue. This figure excludes the direct costs of producing goods or services sold, known as Cost of Goods Sold (COGS), and also separates out non-operating expenses. This article explains how to identify, gather, calculate, and interpret these fundamental business costs.

Understanding Operating Cost Categories

Operating costs generally fall into two broad categories: fixed and variable. Fixed operating costs remain relatively constant regardless of the business’s activity level within a given period. Examples include monthly rent payments for office or retail space, which typically involve a lease agreement outlining a consistent amount. Annual insurance premiums for general liability or property coverage also represent a predictable fixed expense. Salaries paid to administrative staff, such as office managers or human resources personnel, are usually considered fixed as they do not fluctuate with sales volume. Depreciation, the systematic expensing of an asset’s cost over its useful life, is also a fixed operating cost, even though it is a non-cash expense.

Variable operating costs, in contrast, fluctuate directly with the level of business activity or sales volume. Utility expenses, such as electricity and water for a manufacturing facility, will typically increase with higher production levels. The cost of office supplies, like paper or printer ink, will rise as more administrative work is performed. Sales commissions paid to employees are a direct example of a variable cost, as these payments are usually a percentage of sales revenue. Marketing expenses, including advertising campaigns or promotional materials, often vary based on sales goals or market conditions.

Operating costs are distinct from Cost of Goods Sold (COGS), which covers direct production costs like raw materials and labor. They also exclude non-operating expenses, such as interest on loans or income taxes, and losses from asset sales. These are explicitly excluded from operating costs.

Gathering the Necessary Financial Information

To accurately calculate operating costs, businesses must first gather the necessary financial data for a specific accounting period. The primary document for this purpose is the company’s income statement, also known as a profit and loss (P&L) statement. This statement summarizes a company’s revenues, expenses, and profits over a period, such as a month, quarter, or year. Operating expenses are usually grouped together on this statement, often appearing after the Cost of Goods Sold.

Businesses can locate specific expense line items like rent, utilities, salaries, marketing, and office supplies on the income statement. For a more detailed breakdown, other financial records like the general ledger, individual invoices, payroll records, and bank statements can offer granular information. Selecting a consistent accounting period, such as the most recent fiscal quarter or year, is important to ensure the data is comparable and provides a relevant snapshot of operational spending.

Step-by-Step Calculation of Operating Costs

The calculation of total operating costs involves a straightforward process once financial information has been gathered. The first step is to list every identified operating expense for the chosen accounting period. This includes all fixed costs like rent, insurance premiums, and administrative salaries, as well as variable costs such as utilities, office supplies, and marketing expenditures. Businesses should use the exact figures recorded in their financial statements for accuracy.

The next step involves reviewing the listed expenses to exclude any items that do not qualify as operating costs. This means removing Cost of Goods Sold (COGS) and any non-operating expenses, such as interest paid on debt or income taxes. For example, a one-time loss from selling an old delivery truck would also be excluded from operating costs.

After excluding non-operating and direct production costs, the final step is to sum all the remaining qualifying operating expenses. For instance, if a business had $2,500 in rent, $300 in utilities, $4,000 in administrative salaries, and $500 in marketing expenses for a month, the total operating costs would be $2,500 + $300 + $4,000 + $500, equaling $7,300. This sum represents the total expenditure incurred to run the core business operations for that specific period.

Interpreting Your Operating Cost Calculation

The calculated operating cost figure represents the total expense required to run the core business operations for a defined period. This number provides a clear understanding of the financial outlay necessary to maintain daily activities, separate from production costs or financial obligations. It directly reflects how much it costs to keep the doors open and the business functioning.

Businesses often compare this total operating cost to their revenue to gauge operational efficiency. Expressing operating costs as a percentage of revenue reveals how much of each dollar earned is consumed by daily operations. Monitoring this percentage over several accounting periods can indicate trends in business expenditure, showing if costs are rising or falling relative to sales. A consistent increase in this percentage without a corresponding increase in revenue could signal inefficiencies.

Understanding operating costs also contributes to a business’s overall profitability assessment. The calculated figure is a direct input into determining operating income. Operating income is derived by subtracting total operating costs from the revenue generated during the same period. This calculation, Revenue minus Operating Costs, highlights the profit a business generates from its core operations before accounting for interest and taxes.
