Summary
Operating costs are the costs of running a business’s core activities. They include both the direct costs of delivering a product or service and the operating expenses required to support the business. Operating expenses are the overhead portion, such as marketing, office rent and administrative salaries. Separating the two helps you understand gross profit, operating profit and where you can improve efficiency.
What are operating costs?
Operating costs are the expenses associated with a business’s normal, revenue-generating activities. In this article, the term includes two main categories:
1. Direct costs: Costs of producing goods or delivering services, often reported as cost of goods sold (COGS), cost of sales or cost of services.
2. Operating expenses: Costs of running and supporting the business that are not directly assigned to the goods or services sold.
For example, a flooring company might count the materials and installation labour for a customer job as direct costs. Its office rent and advertising are operating expenses. Together, those categories make up its operating costs under the definition used here.
Interest on a loan and income taxes generally appear separately from operating profit on an income statement. A major equipment purchase also should not automatically be treated as a current-period operating expense; how it is recorded depends on the applicable accounting rules.
What are operating expenses?
Operating expenses, often called OpEx, are the costs of keeping a business running that are not directly tied to producing or delivering a specific sale.
Common examples include:
· Marketing and advertising
· Administrative wages and benefits
· Office rent and utilities
· Business insurance
· Accounting and legal fees
· Software used for general administration
A cost’s purpose matters more than its label. Employee wages, for example, may be a direct service cost when the employee delivers client work, while a payroll administrator’s wages are usually overhead. Shared costs may need a consistent allocation method.
Operating costs vs. operating expenses at a glance
| Question | Direct costs of goods or services | Operating expenses |
| What do they cover? | Producing or delivering what customers buy | Supporting and managing the business |
| Common examples | Materials, direct labour, job-specific subcontractors | Marketing, office rent, administrative staff |
| Where do they appear? | Above gross profit | Below gross profit and above operating profit |
| What do they help explain? | Gross profit and the cost of delivery | Overhead and operating profit |
Both columns are part of operating costs as that term is used in this article. Many income statements show the categories separately because they answer different management questions.
How do you calculate operating costs?
Use figures from the same accounting period and avoid counting any cost twice:
Operating costs = cost of goods sold or services + operating expenses
Suppose a service business has the following results for one month:
| Income statement item | Amount |
| Revenue | $50,000 |
| Direct cost of delivering client work | $20,000 |
| Gross profit | $30,000 |
| Operating expenses | $18,000 |
| Operating profit | $12,000 |
Its operating costs are $20,000 + $18,000 = $38,000. Gross profit is $50,000 − $20,000 = $30,000. Operating profit is $30,000 − $18,000 = $12,000, before any separately reported non-operating items and income taxes. These figures are illustrative.
For a service business, the direct-cost line may be called cost of services or cost of revenue instead of COGS. Use the labels and classifications in your own books consistently so that comparisons over time remain meaningful.
Why does the difference matter
You can price work with a clearer view of delivery costs.
If a project brings in $5,000 but requires $4,000 in labour and subcontractor costs, it leaves only $1,000 in gross profit to cover overhead and contribute to profit. Revenue alone would make the job look healthier than it is.
You can see whether the problem is delivery or overhead.
If direct labour costs rise faster than revenue, review estimates, scheduling, and how long projects take. If operating expenses rise, review recurring subscriptions, administrative processes, rent, and marketing spend. Different causes call for different fixes.
You can make better hiring and capacity decisions.
Accurate labour hours help show when overtime is climbing, which jobs routinely exceed estimates and where administrative tasks consume staff time. That information can guide staffing and process changes without assuming that every higher cost is waste.
How time tracking helps you manage operating costs
Time tracking adds detail to one of the most important cost drivers: labour. Recording hours against clients and projects can help a business compare planned work with actual work and understand what it takes to deliver a service. Tracking hours for payroll and reviewing overtime can also help managers spot changes earlier.
eBillity’s Time Tracker Workforce offers employee time tracking, timesheet approvals, overtime tracking and workforce reports. Businesses that also need job costing, project tracking, expenses and billing can explore Time Tracker Premium. Your accounting system and bookkeeper or accountant still determine how those hours and expenses are classified on the income statement.
Turn clearer costs into better decisions.
Start by separating direct delivery costs from overhead on your income statement. Then review both categories alongside revenue each month. Look for patterns: rising cost per project, repeated overtime, or overhead that grows without a clear return. Once you know which costs are changing, you can address the cause and measure whether the change improves your margins.

FAQs
Are operating costs and operating expenses the same thing?
No. In this definition, operating costs include both direct costs of goods or services and operating expenses. Operating expenses are the overhead portion of operating costs.
Is payroll an operating cost or an operating expense?
It depends on the work performed. Labour directly involved in producing goods or delivering a service may be classified as a direct cost. Administrative, sales or management payroll is generally an operating expense. Follow a consistent method for employees whose time spans both activities.
Is rent an operating expense?
Office rent is generally an operating expense. Rent for a production facility or another space used directly to deliver goods or services may be treated differently depending on how the business accounts for direct costs.
What is the difference between gross profit and operating profit?
Gross profit is revenue minus the direct costs of goods or services. Operating profit is gross profit minus operating expenses. The first shows what remains after delivery costs; the second shows what remains after overhead.
How can a service business track its operating costs more accurately?
Record employee hours by client or project, capture job-specific expenses, reconcile those records with payroll and accounting data, and review direct costs and overhead each month. Consistent records make it easier to spot work that takes longer or costs more than expected.
