A cost center is a unit of an organization, a department, a function, a team or a single piece of equipment, that a business collects costs against and holds one manager accountable for. That manager controls the unit’s spending but is not accountable for the revenue those costs help produce, or for the capital the unit employs. The managerial statement of it runs to one line: a cost center is an organizational segment in which a manager is held responsible only for costs (OpenStax, Principles of Accounting, Volume 2: Managerial Accounting, section 9.3).
The Two Senses of the Word
The word is used in two places, and the two uses are not the same claim about the business.
The first sense is a scope of managerial accountability. It belongs to responsibility accounting, the system that assigns financial accountability for a segment of the business to a named manager, and it reports inward rather than to any outside reader, so it sits inside managerial accounting. Calling a unit a cost center in this sense says what its manager will be judged on, and nothing else.
The second sense is a segment of the account code. Here the cost center is a dimension carried on the expense posting alongside the account itself, so every dollar of spend lands with a label naming the unit it belongs to. The federal managerial cost accounting standard describes that use directly: a network of cost centers can be established within a segment to accumulate costs, and cost centers can be structured along different dimensions, such as organizational units, operating processes, and activities (FASAB, Statement of Federal Financial Accounting Standards 4, paragraph 88).
A Cost Center Collects Cost, It Does Not Spread It
The purpose of a cost center is accumulation. It is the place costs are gathered, not a rule for dividing them up, and the two acts are separate steps that happen in that order.
Spreading is the second step, and it runs on different machinery. Which costs can be tied to one recipient in the first place is the traceability question worked through in direct cost and overhead. The act of assigning a pooled cost to a recipient on a stated basis is allocation. The measure that decides how much each recipient carries, and the rate built on it, sit in costing overheads, and splitting one rate into several by activity is activity based costing. A cost center can exist and report for years without any of that running against it.
What a Cost Center Is Not
A profit center adds revenue accountability to the same structure, because a profit center is an organizational segment in which a manager is responsible for both revenues and costs (OpenStax, Principles of Accounting, Volume 2: Managerial Accounting, section 9.3).
An investment center adds capital on top of that, since its manager is accountable for profits, meaning revenues minus expenses, and the invested capital used by the segment (OpenStax, Principles of Accounting, Volume 2: Managerial Accounting, section 9.3).
A department is a unit on the org chart, which is a different kind of thing again, and it may map to one cost center, to several, or to none. The federal standard is explicit that the two do not have to line up: a cost center can be at any level of an organization and may not report to the top management directly (FASAB, Statement of Federal Financial Accounting Standards 4, paragraph 82), and management may define sub-units, functions, projects, business processes, activities, or a combination of them as cost centers to accumulate costs (FASAB, Statement of Federal Financial Accounting Standards 4, paragraph 194).
Cost Centers Inside a US CPA Firm
The split in a firm follows what bills. Tax, audit and advisory carry revenue as well as cost, so under this scheme they are profit centers rather than cost centers. Administration, information technology, marketing and firm management do not bill anyone, so they are usually run as cost centers, and their spend is recovered across the practice areas that do bill.
Coding the ledger that way is what makes departmental spend reportable on its own. Once every invoice, subscription and salary carries a center, a firm can say what administration cost last month without running a single allocation, and it can hold one person to that number. Charging those costs out to the billing units is a later decision the firm may or may not make.
Common Questions
It means a unit the business collects costs against and holds one manager accountable for. The manager answers for what the unit spends, and not for revenue or for the capital it uses.
A department is an organizational unit on the chart, while a cost center is a costing and reporting unit. They often line up, but one department can hold several cost centers, and a cost center can be a process or an activity rather than a department at all.
There is no exact synonym. It is one member of the family of responsibility centers, and the British spelling is cost centre. It is emphatically not a revenue center, which carries the opposite accountability: a revenue center is an organizational segment in which a manager is held accountable only for revenues (OpenStax, Principles of Accounting, Volume 2: Managerial Accounting, section 9.3).
An information technology function is the standard example, because it consumes salaries, licenses and hardware while billing nobody outside the business. A maintenance department is another, as is a firm’s administrative team, and so is a marketing function whose spend supports sales it does not book. A single machine or one building can be a cost center too, since the unit is chosen for how the business wants to report cost rather than for its place on the chart.
