How Much Admin Expense Should a Firm Incur?

Marc Rosenberg, CPA / Dec 15, 2014

profitabilityA reader whose firm traditionally measures admin expense as a percentage of revenue recently queried whether we could share any industry benchmarks along these lines.

There are 3 metrics used for measuring admin expense: (a) Admin personnel as a percent of total headcount, (b) Overhead expenses as a percentage of revenue and (c) Overhead expenses per person. Let’s examine each.

Admin personnel as a pct of total simply measures the appropriateness of the number of admin people a firm has in comparison to total personnel.  For years we have seen firms’ admin personnel hover right around 20% of total personnel  So, if a firm has 30 FTEs, one would expect 6 admin staff, with a range of 5 to 7.

A firm with admin staff at 15% or below is usually one where partners and professional staff do admin work themselves. Most firms find that professionals doing admin work is a misguided use of time and skills.

Firms whose admin staff is higher than 25% of total headcount may have efficiency problems. There could be some “sacred cows” on board – people being retained out of loyalty whose skill sets haven’t kept pace with the firm’s growth. Firms with multiple offices might also have duplicate positions in each office that wouldn’t be incurred otherwise.

Overhead expense as a percent of revenues as measured in The Rosenberg Survey comes in for most firms at around 20-25% of revenue. Overhead expense is defined as ALL expenses of the firm EXCEPT salaries and benefits of professional staff and admin personnel. Main components are rent, insurance, computer expenses, training, bad debts expenses, marketing, etc.  

Overhead expenses per person is another way to measure the reasonableness of a firm’s admin expenses.   For most firms, this is $35,000 to $45,000.

One final thought:  While meaningful, comparing your firm to statistical norms comes with a caveat.  The more profitable firms (those with income-per-partner in excess of $500,000) will always show various income statement items as a lower percentage of revenue than less profitable firms, simply because their revenues are higher (the metrics correlating the strongest to profitability are revenue per partner and revenue per person).  And the opposite is true:  less profitable firms (say firms with IPP less than $250K) will show their income statement items as a higher percent of revenues than more profitable firms.  Example:  Take the case of two identical firms in terms of number of personnel, salaries paid to those personnel and amount of overhead expenses.  One firm’s revenue is 20% higher than the other because they are more productive, charge higher rates, better at business-getting, get higher realization due to superior management, etc etc. The firm with the higher revenues will always show their admin expenses lower as a percent of revenues. That’s the way the math works!

The most profitable CPA firms in the country enjoy an income per partner (IPP) of $909,000. The least profitable firms have IPP of $200,000. That’s a 4.5 to 1 spread of high to low. What are the most profitable firms doing right and what are the least profitable firms doing wrong? The answer – actually there are roughly 50 answers – lies within the covers of What Really Makes CPA Firms Profitable.
