Expense allocation definition
/What is an Expense Allocation?
An expense allocation occurs when indirect costs are assigned to cost objects. Expense allocations are required by several accounting frameworks in order to report the full cost of inventory in the financial statements.
A cost object is anything for which a cost is compiled. Examples of cost objects are products, product lines, customers, sales regions, and subsidiaries. An indirect cost is a cost that is not associated with a single activity. Examples of indirect costs are facility rent, utilities, and office supplies.
A company may allocate its indirect costs in order to determine the entire cost of a cost object on a full absorption basis. Full absorption refers to the assignment of all possible costs to a cost object, so that the costs of all activities are considered. This approach is required under the Generally Accepted Accounting Principles (GAAP) and International Financial Reporting standards (IFRS) accounting frameworks.

Expense Allocation Inaccuracies
By its definition, an allocation is bound to be imprecise. Thus, the resulting full absorption costing of a cost object is inherently inaccurate. If a business does not require an overly precise expense allocation, it can rely upon a simple formula that is easy to derive. This approach is commonly taken when using expense allocation to comply with the dictates of an accounting standard. However, if considerably more precision is needed, perhaps to make a management decision, then a more complex allocation method can be used, such as the activity-based costing system.
Types of Expense Allocation Methods
Types of several types of expense allocation methods are noted below:
Direct labor hours. Factory overhead costs are routinely allocated to products based on the number of direct labor hours used in the production of the products. The resulting allocation can be quite inaccurate, but is easy to derive. This approach is commonly used, because many organizations already have processes in place for tracking how direct labor hours are used.
Revenue-based allocations. The cost of corporate headquarters may be allocated to subsidiaries based on their revenue. The reasoning behind this allocation is that the subsidiary with the highest activity level can afford to bear the burden of corporate overhead. However, this logic ignores whether subsidiaries are earning a profit.
Square footage-based allocations. If a cost object (such as a production line) takes up a fair amount of square feet, those expenses related to facilities costs can be allocated based on the square feet used by the cost object. This is not difficult to do, since the square footage used rarely changes.
Staffing-based allocations. If the bulk of a company's costs are related to personnel costs, consider allocating the indirect costs of personnel based on the number of employees or the number of labor hours consumed. This approach works best in a services business, where there are many employees and the bulk of all expenses are related to personnel.
Example of Expense Allocation
A company operates three departments, which are manufacturing, sales, and administration. The company incurs $60,000 annually for building rent, which benefits all departments. To allocate the rent expense fairly, the company decides to use floor space (square footage) as the allocation basis. Manufacturing occupies 50% of the space, Sales occupies 30%, and Administration uses the remaining 20%. Based on this allocation, Manufacturing will be assigned $30,000 (50% of $60,000), Sales will receive $18,000 (30% of $60,000), and Administration will be charged $12,000 (20% of $60,000). This allocation process ensures that each department reflects its share of the rent expense in its financial records.
