The basis of apportionment is critical in accounting and cost management, ensuring that overhead costs are distributed fairly among various cost centres within an organization. This concept plays a crucial role in providing accurate cost information for decision-making, budgeting, and financial reporting.
Historical Context
The concept of apportionment has evolved with the development of cost accounting practices. Historically, businesses recognized the need for a systematic approach to allocate indirect costs, such as rent and utilities, to various departments to reflect their actual resource usage. Over time, various methods and bases for apportionment have been developed to enhance fairness and accuracy.
Types of Apportionment Bases
- Floor Area: Used when costs such as rent need to be apportioned based on the space occupied by each department.
- Number of Employees: Applied in cases where costs like canteen expenses or HR-related costs are divided based on the employee count.
- Machine Hours: Utilized in manufacturing environments where costs are allocated based on the hours machines are in operation.
- Direct Labor Hours: Appropriate when costs are proportional to the time spent by workers in each department.
Key Events and Developments
- Industrial Revolution: Brought complexity to cost allocation with the rise of large-scale manufacturing.
- Introduction of Activity-Based Costing (ABC): Enhanced the precision of overhead allocation by focusing on activities that drive costs.
- Adoption of Technology: Modern accounting software has simplified and automated the apportionment process.

D --> |Floor Area| G[Allocated Cost]
Importance and Applicability
A proper basis of apportionment is crucial for:
- Accurate Costing: Ensures all departments are fairly charged for overheads.
- Performance Evaluation: Helps in assessing the efficiency and profitability of each department.
- Strategic Decision Making: Provides management with precise cost data to make informed decisions.
Examples
- Rent Apportionment: In a company with three departments, if Department A occupies 40% of the floor area, Department B 35%, and Department C 25%, the rent is apportioned accordingly.
- Utility Costs Apportionment: Using the number of employees, if Department A has 50 employees, Department B has 30, and Department C has 20, the utility costs are divided based on these numbers.
Considerations
- Fairness: The chosen basis should reflect actual usage to ensure equity.
- Simplicity: While the method should be straightforward, it should not compromise accuracy.
- Consistency: Use consistent apportionment bases for comparability over time.
Related Terms
- Allocation Base: The measure used to assign costs to cost centres or products.
- Overhead Costs: Indirect costs not directly traceable to a single product or department.
- Cost Centre: A unit within an organization to which costs are allocated.
Comparisons
- Apportionment vs Allocation: Allocation assigns costs directly to a cost centre, while apportionment distributes costs among several cost centres.
- Traditional Costing vs Activity-Based Costing (ABC): Traditional costing uses a single base, while ABC uses multiple bases to assign costs.

Summary
The basis of apportionment is a fundamental aspect of cost accounting that ensures the fair and equitable distribution of overhead costs among various cost centres. By employing different apportionment bases such as floor area, number of employees, machine hours, and direct labor hours, businesses can achieve accurate cost allocation, leading to better decision-making and financial management. The evolution of apportionment practices, especially with the advent of Activity-Based Costing (ABC) and technological advancements, underscores its significance in modern accounting. Through careful consideration of fairness, simplicity, and consistency, organizations can maintain precise and efficient apportionment systems.
