What it means
Every business carries costs that cannot be traced to a product or a customer. The finance team, the human resources department, the chief executive's salary, the head office lease, audit fees and the accounting system all consume money without directly producing anything to sell.
Administrative accounting captures those costs in the general and administrative section of the income statement, then organises them into budgets, cost centres and variance reports. The point is accountability: an office manager who owns a $340,000 budget behaves differently from one who does not.
Its second job is allocation. When a head office serves three divisions, someone must decide how much of the cost each division carries, using drivers such as headcount, floor space, revenue or transaction volume, and that choice changes which divisions appear profitable.
Allocation is also a reliable source of argument. Divisional managers resent being charged for costs they cannot influence, so well-designed reports separate controllable costs from allocated ones and judge managers only on the first group.
The standard health check is the administrative expense ratio, administrative costs divided by revenue. There is no universally correct level, but a ratio drifting upward while revenue is flat is a dependable early warning that the back office is growing faster than the business it supports.
In practice
Real-world examples.
Example
A charity with $8,000,000 of donation income reports administrative costs of $880,000, or 11%, in its annual accounts. The board watches the ratio closely because major donors treat it as a crude efficiency test, even though an underfunded back office creates problems of its own.
Example
A manufacturer with four plants charges group insurance, audit and legal fees to sites by floor space. The newest plant, physically large but lightly staffed and highly automated, ends up carrying 40% of the charge, and its manager successfully argues for headcount as a fairer driver.
Example
A growing software company holds administrative headcount flat for two years while revenue rises from $6,000,000 to $10,000,000, so administrative costs of $1,200,000 fall from 20% to 12% of revenue. The board reads the improvement as evidence that the model scales rather than as a cost cut.
Formula
Calculation
Administrative expense ratio = administrative expenses / revenue
Allocated administrative cost = total administrative cost x (division's driver units / total driver units)
A services group has revenue of $12,000,000 and administrative expenses of $1,560,000, giving an administrative expense ratio of $1,560,000 / $12,000,000 = 13%.
The group allocates head office costs to its two divisions by headcount. Total headcount is 120, split 45 in consulting and 75 in managed services, so the rate is $1,560,000 / 120 = $13,000 per employee. Consulting is charged 45 x $13,000 = $585,000 and managed services 75 x $13,000 = $975,000, and $585,000 + $975,000 = $1,560,000 confirms the whole cost has been spread.
Change the driver and the answer changes with it. If the group allocated by revenue instead, and consulting produced $7,200,000 of the $12,000,000, consulting would carry $1,560,000 x ($7,200,000 / $12,000,000) = $936,000, which is $351,000 more than under headcount, on exactly the same underlying costs.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Marlow and Fenn Group, an invented professional services firm with three offices, allocated $2,400,000 of head office cost across its offices by share of revenue. The northern office generated $3,000,000 of the group's $12,000,000, so it was charged 25% of the cost, or $600,000. Against its own direct profit of $520,000 that produced a reported loss of $520,000 - $600,000 = -$80,000, and the board began drafting a closure plan.
The managing partner asked for the allocation to be tested before anyone acted. A review found the northern office employed 9 of the group's 90 staff, generated 6% of finance transactions, used no central marketing support and ran its own small administration team. Reallocating on headcount gave a charge of $2,400,000 x (9 / 90) = $240,000, which turned the reported loss into a profit of $520,000 - $240,000 = $280,000.
The fictional group changed its driver to headcount, kept the office open, and started reporting controllable profit above the allocated charge so that managers could see both numbers. The illustrative lesson is that administrative accounting is not neutral bookkeeping: an allocation rule chosen for convenience almost closed the group's second most profitable office.
Watch out
Common mistakes.
- Treating allocated head office charges as controllable and holding divisional managers accountable for costs they have no power to change.
- Picking an allocation driver because the data is easy to obtain rather than because it reflects what actually causes the cost.
- Chasing a lower administrative expense ratio by cutting finance and compliance staff, which usually reappears later as errors, late reporting and audit findings.
Questions
People also ask.
How is administrative accounting different from management accounting?
Management accounting is the broader discipline of producing internal information for decisions, while administrative accounting is the narrower job of recording, budgeting and allocating the organisation's general running costs.
What is a reasonable administrative expense ratio?
It varies enormously by sector, so the useful comparison is against your own trend and close competitors rather than any published benchmark.
Should administrative costs be allocated at all?
Not always, since some groups report divisional results before central costs and hold head office accountable for its own budget, which avoids arguments but can hide the true cost of serving each division.
