Arbitrary Allocation refers to a method of cost allocation where the chosen allocation base does not accurately reflect the real cost distribution among different cost objects. This practice often leads to skewed financial reports and managerial decisions.
Historical Context
The traditional methods of cost allocation have frequently been criticized for their inaccuracies, which led to the development of more precise systems like Activity-Based Costing (ABC). Arbitrary allocation methods were common before more sophisticated allocation techniques were developed.
Types/Categories
- Fixed Allocation: Costs are spread evenly, regardless of actual usage.
- Proportional Allocation: Costs are allocated based on a proportionate method, often unrelated to the actual cost incurrence.
- Random Allocation: Costs are allocated randomly, usually in the absence of a logical base.
Key Events
- 1980s: Introduction and popularity of Activity-Based Costing (ABC), aiming to avoid arbitrary allocations.
- 1990s: Increased focus on precision in cost accounting due to global competition.
- 2000s: Widespread adoption of sophisticated cost management software.
Detailed Explanations
Mathematical Models
Let’s consider a hypothetical scenario where $C$ is the total cost to be allocated, $n$ is the number of cost objects, and $x_i$ represents the allocation base for the $i$-th cost object.
For arbitrary allocation:
Where:
- \(A_i\) is the allocated cost to the $i$-th cost object.
However, if $x_i$ is not a good representation of the cost driver, the allocation is considered arbitrary.

Importance and Applicability
The precise allocation of costs is crucial for accurate financial reporting and decision-making. Arbitrary allocation can misrepresent profitability, leading to poor business decisions. Fields like manufacturing, education, and healthcare particularly benefit from accurate cost allocation.
Examples and Considerations
Examples
- Education: Allocating the total salary of lecturers based on the number of students can lead to arbitrary cost distribution.
- Manufacturing: Using machine hours instead of setup costs to allocate overheads can be misleading.
Considerations
- Always seek a cause-and-effect relationship between costs and their allocation bases.
- Evaluate the cost-benefit of implementing more precise allocation methods like ABC.
Related Terms

- Cost Driver: A factor that causes the cost of an activity to increase.
- Direct Cost: Costs that can be directly attributed to a cost object.
Comparisons
Arbitrary Allocation vs. Activity-Based Costing:
- Accuracy: ABC is generally more accurate.
- Complexity: Arbitrary allocation is simpler to implement.
Interesting Facts
- Many companies in the 1980s realized their costing systems were arbitrary and shifted to ABC, which led to significant cost savings.
- Modern ERP systems can handle complex cost allocations, reducing the prevalence of arbitrary methods.
Inspirational Stories
Toyota: Shifted from traditional to ABC costing and improved their cost management, maintaining their edge in the competitive automotive market.

Summary
Arbitrary Allocation may simplify cost distribution but can significantly distort financial reporting and decision-making. Modern costing methods like Activity-Based Costing offer more accurate and beneficial alternatives, improving the quality of financial information and operational efficiency.
