What is the difference between a cost center and a profit center?

A cost center tracks expenses and is measured by how closely actual spending matches its budget. A profit center is accountable for both revenue and costs, with net income as its primary metric. IT, HR, legal, and corporate travel typically operate as cost centers; business units and product lines often operate as profit centers.

What are examples of cost centers in a company?

Common cost centers include IT, human resources, legal, marketing, accounting, research and development, facilities management, and corporate travel. Any department that incurs expenses in support of the business without directly generating sales qualifies as a cost center.

How do cost center codes work in expense management?

Cost center codes are assigned to every expense transaction so finance teams can attribute spending to the department that incurred it. Employees select a code when submitting expense reports, and finance uses those codes for budget variance analysis. Navan Expense pre-populates cost center codes based on a traveler's department profile, reducing the manual selection errors that create reconciliation work at month-end.

How many cost centers should a company have?

Most mid-market organizations operate effectively with 20 to 50 cost centers. More granular structures create assignment confusion and reconciliation complexity. Finance teams should match each cost center to one named budget owner, review the structure quarterly to retire obsolete codes, and avoid adding new cost centers without clear budget accountability.

What happens when cost center codes are wrong on expense reports?

Incorrect cost center codes send spending to the wrong departmental budget, requiring manual journal entries to correct the general ledger at month-end. Systematic miscoding obscures which departments are actually over budget. Navan Expense reduces this risk by pre-assigning cost center codes at the point of booking, before the expense report is even submitted, cutting down the correction cycle that follows close.

What Is a Cost Center? Types & Examples

Key Takeaways

A cost center is a department or functional unit within a company that incurs expenses but does not directly generate revenue. Finance teams use cost centers to track spending by department, allocate budgets, and evaluate how efficiently each unit operates. Navan connects expense data to cost centers automatically, giving finance teams real-time visibility into departmental spend.

Navan Expense auto-assigns cost center codes to transactions at the point of booking, reducing the manual coding errors that compound into reconciliation work at month-end close.
Cost centers differ from profit centers: cost centers manage spending without revenue responsibility, while profit centers are accountable for both revenue and costs simultaneously.
The Skift and Navan 2026 survey found 71% of travelers spend 30-plus minutes filing a single expense report, a burden that manual cost center coding compounds.
A Forrester TEI study commissioned by Navan found that automated expense workflows saved 80% of the time previously spent processing each expense report.

What is a Cost Center?

A cost center is a department, team, or functional unit within a company that tracks and incurs costs but does not directly generate revenue. The term is foundational in accounting and expense management, serving as the basic organizational unit for allocating, tracking, and controlling spend across a business.

Unlike a profit center (which is evaluated on net income), a cost center's performance is measured by how closely actual spending tracks against its allocated budget. Finance teams assign a cost center code to every transaction, from a hotel stay to a software subscription, so that spending can be attributed to the department that generated it. This attribution turns raw expense data into actionable budget analysis.

Cost center management is a core responsibility for any finance team running a travel and expense (T&E) program. When travel charges aren't tied to specific cost centers, finance can see total spending but can't determine which departments are over budget, which trips delivered value relative to cost, or where policy enforcement should focus.

Cost center vs. profit center vs. revenue center

The three organizational unit types are often confused, but they differ in accountability:

Cost center: Tracks expenses only. Performance measured against budget. Examples: IT, human resources, legal, marketing, travel operations.
Profit center: Accountable for both revenue and costs. Net income is the primary metric. Examples: product lines, business units, regional divisions.
Revenue center: Focuses on sales generation with limited cost responsibility. Examples: sales teams with quota targets but centralized cost allocation.

Most corporate departments operate as cost centers. Travel managers, finance teams, and HR don't sell products, but they incur significant spend in support of the business.

Types of cost centers

Cost centers generally fall into two main categories. Service cost centers support the rest of the business without producing a sellable output. Human resources, IT, legal, accounting, corporate travel, and facilities management are common examples. Their costs are often allocated to other departments through internal charge-back mechanisms.

Production cost centers are directly involved in creating goods or delivering services. Manufacturing lines, quality control, and order fulfillment all qualify. These remain cost centers as long as performance is measured by cost efficiency rather than output revenue.

Some organizations add a third category for project-based or geographic cost centers, where a temporary initiative or regional office is tracked separately until it generates revenue, closes, or merges into an existing reporting structure.

Why cost centers matter for T&E programs

Corporate travel is one of the most visible expense categories managed at the cost center level. A sales director who books a client trip generates travel spend that belongs to the sales cost center, not to the IT budget or the HR function. Without cost center tracking, a finance team sees total travel spending but can't answer which departments are over budget or where to focus spend visibility efforts.

Global business travel spending is projected to reach $1.57 trillion by end of 2025, per GBTA's 2025 Business Travel Index [1]. For companies running T&E programs at that scale, assigning every booking, hotel stay, and meal to the right cost center isn't optional. Accurate cost center attribution is the foundation of any meaningful spend analysis.

How cost center coding works in expense management

Every expense management workflow depends on cost center codes to route spending to the right departmental budget. The practical challenge is that employees don't always know which code applies, and finance teams spend time chasing corrections after month-end close.

The Skift and Navan 2026 State of Corporate Travel and Expense survey found that 71% of travelers spend 30 minutes or more submitting a single expense report [2]. Manual cost center selection is one of the friction points embedded in that process. Employees must look up the correct code, apply it to each line item, and hope they've chosen correctly, a step that becomes error-prone for those who travel across multiple projects or departments.

Navan Expense addresses this by auto-assigning cost center codes based on a traveler's department profile. Employees can override the default when a trip serves a different cost center, such as when a team member books travel for a cross-functional project. This default-assignment approach cuts down the coding errors that create reconciliation work at month-end. A Forrester TEI study commissioned by Navan found that automated expense workflows saved 80% of the time previously spent processing each expense report [3]. Expense report automation that includes cost center pre-assignment reduces the manual correction cycle that consumes finance teams during close.

Best practices for cost center management

Finance teams that manage cost centers effectively share a few common approaches:

Keep the code list manageable: A cost center structure with hundreds of granular codes creates more confusion than clarity. Most mid-market organizations operate effectively with 20 to 50 cost centers, adding more only when a business unit or initiative genuinely requires separate tracking.
Match codes to budget owners: Every cost center should have one named owner. Ambiguity about who controls a cost center's budget guarantees disagreements during variance reviews.
Review allocations quarterly: Cost centers that were logical when defined often outlive the organizational structure that created them. A quarterly review identifies codes that have become obsolete, merged, or split.
Connect to booking data: By the time an employee submits an expense report, the money is already spent. Integrating cost center codes at the point of booking gives finance teams spend data before the fact rather than reconstructing it weeks later.

When should you reconsider your cost center structure?

Cost center structures tend to outlive the organization that designed them. A company that grows through acquisition may inherit a different cost center taxonomy. Merging the two without deliberate reconciliation creates double-counting and gaps in spend attribution. Similar issues arise after reorganizations that move departments under new leadership while cost center codes remain mapped to old reporting lines.

Cost center proliferation is the opposite problem: finance teams add new codes for every project, initiative, or geography until the taxonomy has hundreds of entries and employees can't reliably assign the correct code. The fix is periodic rationalization, collapsing similar codes and setting governance for creating new ones.

For T&E programs specifically, a misaligned cost center structure shows up as a general ledger that doesn't reconcile to departmental budgets, forcing manual journal entries to correct travel spend at the end of every reporting period.

Expense report: The document or digital submission employees use to claim reimbursement or reconcile card charges; every line item on an expense report maps to a cost center code.
Accounts payable: The function that processes vendor invoices and employee reimbursements; cost center codes on invoices determine where the liability posts in the ledger.
Fiscal year: The 12-month accounting period within which cost center budgets are allocated, tracked, and reported against actual spending.
