Cost and profit centres
Cost and Profit Centres
This topic is assessed in IBDP Business Management at Higher Level (HL) only.
As businesses grow in size and complexity, managing financial performance at the level of the whole organisation becomes increasingly difficult. A single profit and loss account tells a managing director whether the business as a whole is profitable — but it cannot easily reveal which products, departments, or regions are generating value and which are consuming it. Cost centres and profit centres are management accounting tools that divide a business into identifiable units for the purpose of financial monitoring and control.
Cost centres
A cost centre is a section of a business to which costs can be specifically attributed and monitored, but which does not directly generate revenue. Cost centres are typically support or operational functions whose expenditure can be tracked and compared against a budget.
Examples of cost centres include: a human resources department (incurs costs — salaries, recruitment, training — but does not directly sell products), a maintenance department (incurs labour and materials costs), a regional distribution hub (incurs logistics and storage costs), or a research and development team (incurs project costs before any resulting product generates revenue).
The value of designating a cost centre is that it creates accountability: the manager of the cost centre knows exactly what budget they are responsible for, and actual costs can be compared against budget to identify variances. Without cost centre accounting, the total costs of running a large HR function or a distribution network can become invisible within aggregate company accounts.
Profit centres
A profit centre is a section of a business that generates both revenue and costs, enabling a profit (or loss) to be calculated specifically for that unit. Profit centres are typically distinct product lines, geographic territories, business divisions, or retail locations where both income and expenditure can be attributed.
Examples of profit centres include: a supermarket chain where each store is a profit centre (each store has its own revenue from sales and its own costs — staff, rent, utilities); a media company where each magazine title is a profit centre; a manufacturer where each product range is a profit centre; or a professional services firm where each client account is a profit centre.
Profit centres enable management to identify which parts of the business are performing well and which are loss-making. A business that appears profitable at the consolidated level may contain individual profit centres that are loss-making — cross-subsidised by stronger performers. Identifying this is essential for strategic resource allocation.
| Feature | Cost centre | Profit centre |
|---|---|---|
| Financial measure | Costs only | Revenue, costs, and profit (or loss) |
| Generates revenue? | No — support or operational function | Yes — sales or fee income attributed directly |
| Management focus | Keeping costs within budget | Growing revenue and managing costs to maximise profit |
| Typical examples | HR, IT, maintenance, R&D, distribution hubs | Product lines, store locations, regional divisions, client accounts |
| Accountability | Cost centre manager accountable for expenditure | Profit centre manager accountable for profit contribution |
Thornfield Bakeries Ltd operates twelve retail bakery outlets across the south of England, a central production facility, and a head office with shared service functions (HR, finance, marketing). The finance director has designated each of the twelve retail outlets as a profit centre: each outlet records its own sales revenue from bread, pastries, and hot drinks, and its own direct costs (staff, ingredients, packaging, rent). A profit contribution can be calculated for each outlet individually, revealing that ten outlets are profitable, one is breaking even, and one is generating a consistent loss.
The central production facility is designated a cost centre: it does not sell directly to customers; it produces goods that are transferred to the retail outlets at an internal transfer price. Its performance is measured against a production cost budget — whether it produces to specification within agreed cost per unit. The head office functions (HR, finance, marketing) are also cost centres: they incur costs allocated across the business, with each department tracked against its own budget.
This structure allows Thornfield's board to make informed decisions: the loss-making outlet can be investigated, challenged to improve, or closed; the cost centre budgets can be reviewed for efficiency; and the profitable outlets can be used as benchmarks for the others. Without this structure, all performance data would be aggregated into a single P&L that obscures the variation.
Key Takeaways
- A cost centre is a business unit to which costs are attributed and monitored; it does not directly generate revenue.
- A profit centre is a business unit to which both revenue and costs are attributed, enabling a profit or loss to be calculated for that specific unit.
- Both tools create accountability by linking specific financial performance to specific managers or teams.
- Profit centres reveal which parts of the business are performing well and which are loss-making — information obscured by consolidated accounts.
- The same business function can be a cost centre in one organisation and a profit centre in another, depending on how revenue and costs are attributed.
