Cost Centers: Functions, Types, and Benefits
By Markets & Investing DeskUpdated Nov 10, 2026
Definition
A cost center is a department or unit of a business that incurs expenses without directly generating revenue, such as HR, IT, accounting or legal, and whose costs are tracked separately.
Key takeaways
- A cost center manager is judged on actual spending versus budget, since the unit has no revenue to measure profit.
- A budget variance equals actual cost minus budgeted cost, so a positive figure signals overspending.
- An internal order collects costs for a one-off job and is closed later, while a cost center is permanent.
- In the IT example, switching from headcount to support tickets shifts $120,000 from Sales to Engineering.
A cost center is a department, function or other defined unit of a business that incurs expenses but does not directly generate revenue. Human resources, IT, accounting and legal are typical examples. The business tracks the unit’s costs separately so it can budget for them, hold a manager accountable for spending and, where needed, charge those costs to the parts of the company that earn revenue. In British English the term is spelled cost centre. The meaning is the same.
What is a cost center in accounting?
In accounting, a cost center is a label attached to expenses so they can be collected, reported and compared in one place. An invoice for software licenses is coded to the IT cost center. Each employee’s pay is coded to the cost center on that person’s record in the payroll and HR systems. An employee whose time is split between teams may have pay divided across more than one cost center by percentage.
Treating supporting units such as HR, customer support or office maintenance as cost centers shows management what each support function costs and whether that cost is reasonable for what it delivers.
Cost centers belong to a broader system called responsibility accounting, which classifies units by what their managers control:
| Responsibility unit | Manager is accountable for | Typical measure |
|---|---|---|
| Cost center | Costs only | Actual spending vs. budget |
| Revenue center | Revenue | Sales vs. target |
| Profit center | Revenue and costs | Operating profit |
| Investment center | Revenue, costs and capital invested | Return on investment or a similar return measure |
A cost center manager cannot be judged on profit because the unit has no revenue to set against its expenses. An investment center manager is also responsible for the assets employed, so return measures such as return on equity apply at that level.
How cost centers work
- Set a budget. Before the period starts, the cost center receives a spending budget covering salaries, supplies, software, travel and other expenses.
- Record costs. During the period, every expense is coded to the cost center that incurred it.
- Compare actual to budget. At month-end or quarter-end, finance compares actual spending with the budget. The difference is a variance: actual cost minus budgeted cost. A positive figure means overspending (an unfavorable variance), a negative one means underspending (favorable).
- Investigate and adjust. The manager explains significant variances, and the company decides whether to change the budget, the spending or the process.
- Allocate. Where useful, the cost center’s total costs are distributed to the revenue-generating units that rely on it, so each product line or division shows its full cost.
Finance teams typically draft budget templates, consolidate cost center budgets and run the allocation, while each cost center manager owns the spending decisions inside the budget. In enterprise resource planning (ERP) software, cost centers are usually arranged in a cost center hierarchy, for example individual teams rolling up into a department, then a division, then the whole company, so costs can be reported at any level.
Types of cost centers
Service cost centers
Service cost centers provide internal services that other teams depend on. Examples include:
- Mailroom and courier services, which handle internal and external correspondence and deliveries
- Travel and logistics, which arrange employee travel and the movement of goods
Production cost centers
Production cost centers contribute to making a product without selling it. Quality control inspects output against safety and regulatory standards, which helps prevent recalls and customer complaints. Maintenance keeps machinery and production lines running, reducing downtime. In manufacturing cost accounting, production departments themselves are often treated as cost centers that accumulate costs before those costs are assigned to units of product.
Administrative cost centers
Administrative cost centers handle the organization’s internal management. Records management organizes and stores company documents. Business continuity planning prepares and carries out plans to keep the business running after disruptions such as natural disasters or attacks. Accounting, legal and executive offices also commonly sit in this group.
Cost center vs. cost object vs. internal order
- Cost center: an organizational unit that collects costs over time, such as the legal department.
- Cost object: anything whose cost you want to measure, such as a product, customer, contract or project. Cost center costs are often allocated to cost objects.
- Internal order: in ERP systems such as SAP, a temporary collector for costs of a specific job or event, such as a trade show or a one-off system upgrade. It is closed when the job ends, while a cost center is a permanent part of the organizational structure. Some companies use temporary cost centers for similar short-lived purposes, named with a prefix or suffix so they can be closed later.
Methods for allocating costs
Allocation spreads a cost center’s expenses across the units that benefit from it. The goal is a basis that reflects actual use and that department heads accept as fair.
- Direct allocation: costs go straight to the department that uses the service. If only one sales team uses a particular software tool, that team is charged its full cost.
- Step-down allocation: support departments allocate costs in sequence, starting with the one that serves the most other units. IT might allocate to HR first, then HR allocates its enlarged total to the remaining departments. Once a department has allocated its costs, it receives no further allocations.
- Activity-based costing (ABC): costs are assigned based on a measured driver of resource use, such as support tickets, machine hours or transactions, rather than spread evenly.
Worked example (hypothetical)
Assume an IT cost center spends $300,000 a year and supports three departments:
| Department | Headcount | Share of headcount | IT support tickets | Share of tickets |
|---|---|---|---|---|
| Sales | 50 | 50% | 200 | 20% |
| Engineering | 30 | 30% | 700 | 70% |
| Operations | 20 | 20% | 100 | 10% |
Allocating by headcount charges Sales $150,000, Engineering $90,000 and Operations $60,000. Allocating by tickets, an activity-based approach, charges Sales $60,000, Engineering $210,000 and Operations $30,000.
The total is $300,000 either way, but the choice of base moves $120,000 between Sales and Engineering. If managers are evaluated on the costs charged to them, the method directly changes how their performance looks. A base that does not match actual use can also make a division look more or less profitable than it is, which can mislead pricing or investment choices.
Benefits of cost centers
Better resource allocation. Seeing where money goes exposes spending that is out of line with results. If marketing costs are high relative to what campaigns achieve, part of that budget can move to areas producing higher returns.
Risk detection. Close monitoring makes irregular spending visible sooner. An unexplained rise in a cost center can then be traced and corrected before it grows into a larger problem.
Accountability and coordination. When each department owns a budget, managers have reasons to discuss spending, resource needs and priorities with one another. Cost center reporting also feeds budgeting, product pricing and strategic decisions by showing the full cost of each part of the business.
Limitations of cost centers
They are easy targets for cuts. Because cost centers produce no direct revenue, some companies treat them as a drag on results and cut them first in a downturn. Savings can backfire: an underfunded IT department may leave staff on outdated systems that slow work and raise costs through lost productivity.
Performance is hard to measure. Sales teams have revenue targets, but cost centers lack an equally clear output measure. Their contribution has to be judged through defined criteria such as service levels, response times, error rates or qualitative feedback, not only whether they stayed under budget.
Staying under budget is not the same as performing well. A cost center can hit its budget by delaying maintenance or cutting service quality, pushing larger costs into later periods or onto other departments.
Allocations can blur accountability. Allocated costs are usually outside the receiving manager’s control. If a department head is judged on costs that include an allocation they cannot influence, the evaluation reflects the allocation formula as much as their decisions. Many companies report controllable and allocated costs separately for this reason.
FAQs
Is marketing a cost center or a profit center?
Marketing is usually treated as a cost center, because its spending supports sales rather than producing revenue on its own. Some companies set it up as a revenue or profit center when they can attribute sales directly to marketing activity.
Can a cost center become a profit center?
Yes. If a support function starts charging outside customers, or charges internal users at market-based transfer prices, management can measure its revenue and costs together and treat it as a profit center.
The Bottom Line
Managers, finance teams and executives who set budgets or evaluate departments rely on cost center reporting to see what each support function costs. The allocation base should match actual use, because it changes how divisions and their managers appear. Judging cost centers on service levels and error rates as well as budget, and reporting controllable and allocated costs separately, gives a fairer picture than spending totals alone.
