Organization Design

Profit Centers, Cost Centers, and the Accountability Each Creates

Choose what each unit in your company is accountable for — cost, revenue, profit, or return on capital — knowing in advance which behaviour each choice produces, and stop asking managers to be responsible for numbers they cannot move.

What decision this helps you make: What financial measure each unit is held to, which lines belong above and below that measure, whether a capital charge appears at all, and what to do when the honest answer is that a unit is not really a profit centre no matter what the reporting pack calls it.

What this topic is

Responsibility accounting is the practice of holding each unit accountable for a defined slice of the financial outcome. There are four standard slices. A cost centre is accountable for the cost of producing an agreed output. A revenue centre is accountable for sales at prices it does not set. A profit centre is accountable for revenue minus cost. An investment centre is accountable for profit relative to the capital it uses. Each slice hands the manager a different set of decisions, and each produces a distinct and predictable pattern of behaviour.

Why it matters

The label decides what a manager optimises for the next three years. Call a unit a cost centre and it will minimise cost, including cost that was buying something valuable. Call it a profit centre without giving it price authority and it will spend the year arguing about transfer prices and allocations instead of selling. Call it an investment centre and measure it on return percentage and it will decline good projects to protect its average. None of these are failures of character; they are the measure working exactly as specified.

Who should learn it

Executives designing or redesigning a reporting structure; finance leaders who own the divisional P&L format; and unit managers who suspect their scorecard is asking them for something their authority does not reach.

What you will understand

  • The controllability principle, and why almost every reporting pack violates it
  • Why a return-on-investment measure makes good divisions reject good projects
  • How residual income fixes that, and the new problem it introduces
  • How to tell a real profit centre from a cost centre wearing a profit centre's report

Prerequisites

Common misconception

"Making a unit a profit centre gives its manager ownership and sharpens accountability." It does that only when the manager controls both sides of the number. A profit centre whose prices are set centrally, whose volume is delivered by a corporate sales force, whose main input arrives at a transfer price it did not negotiate, and whose report carries an allocated share of head-office cost is accountable for a figure that moves mostly for reasons outside its reach. What sharpens is not accountability but grievance: the manager learns that the fastest route to a better number is a better allocation formula, and spends the year in the finance department rather than with customers.
