Definition
Cost apportionment, also referred to as cost allocation, is the process of assigning a cost, or a group of costs, to different departments, products, or periods. This distribution is done based on specific, logical criteria that reflect the consumption or usage of resources. The aim is to allocate indirect costs (overheads) such as rent, utilities, and administrative expenses in a way that accurately reflects their contribution to various cost centers within an organization.
Examples
-
Rent Allocation: A company rents a building for $10,000 a month. If the company operates three departments (production, sales, and administration), the rent might be apportioned based on the square footage occupied by each department. If production uses 50% of the space, sales uses 30%, and administration uses 20%, the rent apportioned to each department would be $5,000, $3,000, and $2,000 respectively.
-
Utilities Cost Allocation: An organization’s monthly utility bill is $1,200. If the production department accounts for 60% of the utility usage, the sales department 25%, and the administration 15%, the utilities cost will be apportioned as $720 for production, $300 for sales, and $180 for administration.
-
Administrative Salaries Distribution: If the administrative salaries total $5,000 and need to be allocated across three departments (manufacturing, marketing, finance), based on the hours spent by the administrative team supporting each department, the cost can be apportioned proportionally. If 50%, 30%, and 20% of the administrative effort goes into these respective departments, the apportioned costs will be $2,500, $1,500, and $1,000 respectively.
Frequently Asked Questions (FAQs)
What is the difference between cost apportionment and cost allocation?
While often used interchangeably, cost apportionment typically refers to the distribution of costs among several cost centers, while cost allocation is the process of assigning costs directly to specific cost units.
Why is cost apportionment important in accounting?
Cost apportionment ensures that each department or product bears a fair share of the indirect costs, leading to more accurate product costing and financial reporting. It aids in expense accountability and can highlight areas for cost management improvements.
What criteria are commonly used for cost apportionment?
Common criteria include floor space, number of employees, usage levels, machine hours, and direct labor hours. The choice of criterion depends on what most fairly represents the consumption or generation of overhead costs by each department or product.
How does cost apportionment impact financial statements?
Accurate cost apportionment affects the cost of goods sold (COGS) and overhead reported in the financial statements, providing a realistic picture of profits and expenses and enabling better financial decision-making.
Can cost apportionment methods vary between companies?
Yes, companies may use different methods depending on their specific circumstances, industry standards, and managerial discretion.
What are the common challenges in cost apportionment?
Common challenges include identifying an appropriate basis for apportionment, dealing with changes in operational activities, and ensuring consistency in cost distribution over time.
What are some common methods of cost apportionment?
Common methods include direct allocation, step-down allocation, reciprocal allocation, and activity-based costing (ABC), each suitable for different operational and financial contexts.
Is cost apportionment relevant only to manufacturing industries?
No, cost apportionment is relevant across various industries, including services, healthcare, education, and logistics, wherever indirect costs must be distributed among different cost centers.
How frequently should costs be apportioned?
Costs can be apportioned monthly, quarterly, or annually based on the company’s accounting cycle and reporting needs.
