Functional accounting definition
/What is Functional Accounting?
Functional accounting is a reporting format for financial results that clusters results based on the functions performed. This approach is most commonly used to cluster expenses by department, and is commonly used in larger or more complex organizations. For example, a company's expenses may be grouped together in the income statement as follows:
Accounting and finance department
Engineering department
Human resources department
Materials management department
Production department
Sales department
Expenses are clustered together in this manner in order to track and evaluate the performance of individual departments. Thus, functional accounting is a form of responsibility accounting, since the manager of a department is responsible for the expenses charged to his or her department. An example of the functional accounting approach in the presentation of a sample income statement is noted next, where department expenses are highlighted.
Chart of Accounts Numbering
In order to report expenses by function, it is necessary to restructure the chart of accounts of a business. For example, a normal chart of accounts might have a single rent expense account, with a single account code assigned to it. In a functional accounting environment, there must be a separate rent expense designation for each department, so that rent can be allocated to each department. This greatly increases the total number of accounts listed in the chart of accounts. An example follows.
Rent expense - Accounting (#7600-100)
Rent expense - Engineering (#7600-200)
Rent expense - Materials management (#7600-300)
Rent expense - Production (#7600-400)
Rent expense - Sales (#7600-500)
The report writing software in the accounting system then accumulates all expenses based on the department codes in the chart of accounts and uses it to assemble an income statement that is based on functional activities.
Problems with Functional Accounting
A concern with functional accounting is the manner in which expenses are allocated to a functional area. This may be based on a formula, such as the square footage occupied by an office in allocating the total amount of office rent to a department. The problem is that the manager of a functional area may have no input into the calculation of this allocation. Thus, a manager might be able to compress the floor space occupied by her department, and yet still be allocated the same amount of rent expense as before. Because of this lack of control over expense allocations, managers do not have an incentive to reduce certain types of expenses.
