Cost Centres and Profit Centres
When a business has one shop, the owner knows exactly where the money went. With forty shops, three product lines and a head office, that gets impossible. Cost and profit centres are how a large firm breaks itself into pieces small enough to measure.
What you need to know
A cost centre is a part of the business that incurs costs but does not generate revenue.
A profit centre is a part that generates revenue and incurs costs, so it can be judged on profit.
Typical cost centres: human resources, IT support, administration, research.
They exist to improve organisation and control, budget autonomy, accountability and motivation.
Most large firms use both at the same time.
The difference in one line
Ask whether that part of the business sells anything to a customer. If it does, it can be judged on profit. If it does not, it can only be judged on how well it controls its costs. That is the whole distinction.
The same head office function is a cost centre in every firm. What changes between firms is how finely the profit centres are cut.
Type
What it is
How the manager is judged
Cost centre
A department or unit that spends money but earns no revenue of its own
On whether costs stayed within budget
Profit centre
A unit that earns revenue and has costs, so it can cover itself and make a profit
On the profit it produces, and on the full financial result
A supermarket chain runs each store as a profit centre and its head office marketing and HR teams as cost centres. Same company, both systems, different questions being asked of each manager.
What they are actually for
These four roles are the ones examiners expect you to name, so learn them as a set.
Organisation and control
Managers can set a budget for each section and monitor it separately. Performance can be tracked over time and compared between units, which is impossible if all the costs sit in one pile.
Budget autonomy
Budget holders make their own spending decisions without asking head office every time. Decisions are quicker and are made by people who actually know the local situation.
Accountability
Because each unit has its own numbers, a manager’s performance can be measured against how well costs and revenues were handled. That feeds straight into appraisal.
Motivation
Delegating a budget is a real responsibility, and responsibility motivates. Good performance can be seen clearly, so it can be recognised and rewarded.
Advantages and disadvantages
Advantages
Disadvantages
The performance of each part of the business can be assessed, so effort goes where it is needed
Centres may compete with each other, damaging working relationships
Financial decisions are made locally, so prices can suit local market conditions
A “win at all costs” culture can hurt quality or customer service
The people who spend the money are the ones controlling it, which improves cost control
Splitting shared costs fairly between centres is genuinely difficult
Delegation raises responsibility and can motivate lower-level employees
Budget holders need financial skills and training, on top of their normal job
Jobs become more varied and interesting
Training costs money and takes people away from their work
The allocation problem is the strongest evaluation point. How much of the head office electricity bill belongs to the online shop? Any answer is a judgement, and an unfair split makes a good manager look bad.
Exam tip
Learn one clear example of each type. HR is the safest cost centre; an individual store is the safest profit centre.
Say why a unit is one or the other: does it earn revenue directly from customers?
Link centres to motivation theory if you can — delegated budgets give responsibility and recognition.
Multi-site and multi-product firms benefit most, so check the size of the firm in the case study.
In evaluation, weigh better control and motivation against rivalry and unfair cost allocation.
Remember that most large firms use both types together, so do not present it as a choice.
Common mix-up
Thinking a cost centre is a waste. HR and IT are essential; they simply have no revenue of their own.
Assuming every department can be a profit centre. If it does not sell to customers, it cannot be.
Confusing a cost centre with a fixed cost. One is a part of the organisation, the other is a type of cost.
Ignoring the rivalry drawback. Competing centres can hoard information and undercut each other.
Forgetting the training cost. Budget holders are not automatically good with numbers.
Saying centres always improve motivation. An unrealistic target has the opposite effect.
