The Perils of Allocating Common Fixed Costs
The allocation of common fixed costs to a product line is fraught with potential pitfalls, capable of distorting profitability, obscuring accuracy, hindering performance evaluation, and demotivating personnel.
Key Facts
- Misrepresentation of profitability: Allocating common fixed costs to a product line can make the line appear less profitable than it actually is. This is because common fixed costs are costs that cannot be directly traced to a specific product or department, and allocating them based on arbitrary methods can distort the true profitability of the product line.
- Lack of accuracy in cost allocation: The choices made regarding the allocation base, rate, and order may not accurately reflect the cause-and-effect relationships or the benefits received by products or departments. This can result in arbitrary, subjective, and inconsistent allocation results, further distorting the true costs associated with the product line.
- Distortion of performance measures: Allocating common fixed costs that are not related to the cost driver or cost behavior can distort the performance measures of products or departments. If the allocation base does not align with the actual cost drivers, it can lead to inaccurate assessments of the efficiency and effectiveness of the product line.
- Disincentives for managers and employees: Allocating a large portion of common fixed costs that are beyond the control of managers can create demotivation and resentment. On the other hand, allocating a small portion of common fixed costs that are easy to control can remove incentives for managers to reduce costs. This can hinder the overall performance and cost management efforts of the product line.
Misrepresentation of Profitability
Allocating common fixed costs can paint an inaccurate picture of a product line’s profitability. These costs, not directly attributable to a specific product or department, are often assigned based on arbitrary methods, leading to distorted profitability assessments.
Lack of Accuracy in Cost Allocation
The allocation of common fixed costs is often based on subjective criteria, such as the allocation base, rate, and order. These choices may not accurately reflect the cause-and-effect relationships or the benefits received by different products or departments, resulting in arbitrary and inconsistent allocation results.
Distortion of Performance Measures
Allocating common fixed costs that are not related to the cost driver or cost behavior can distort performance measures. This misalignment can lead to inaccurate assessments of a product line’s efficiency and effectiveness, hindering informed decision-making.
Disincentives for Managers and Employees
Allocating a large portion of common fixed costs that are beyond the control of managers can create a sense of demotivation and resentment, while allocating a small portion of common fixed costs that are easy to control can remove incentives for cost reduction. This can negatively impact the overall performance and cost management efforts of the product line.
Conclusion
In conclusion, the allocation of common fixed costs is a complex and challenging task fraught with potential pitfalls. Organizations must carefully consider the allocation methods and criteria to ensure accurate cost allocation, reliable performance measures, and motivated personnel.

FAQs
How can allocating common fixed costs distort profitability?
Allocating common fixed costs to a product line can make the line appear less profitable than it actually is, as these costs are not directly traceable to specific products and their allocation is often based on arbitrary methods.
What is the impact of inaccurate cost allocation?
Inaccurate cost allocation can lead to arbitrary, subjective, and inconsistent allocation results, further distorting the true costs associated with a product line.
How does allocating common fixed costs affect performance measures?
Allocating common fixed costs that are not related to the cost driver or cost behavior can distort performance measures, leading to inaccurate assessments of a product line’s efficiency and effectiveness.
Why can allocating common fixed costs demotivate managers and employees?
Allocating a large portion of common fixed costs that are beyond the control of managers can create demotivation and resentment, while allocating a small portion of common fixed costs that are easy to control can remove incentives for cost reduction.
What are some of the challenges in allocating common fixed costs?
Challenges in allocating common fixed costs include the lack of a direct relationship between the cost and the product, the subjectivity of allocation criteria, and the potential for distorted information leading to faulty decision-making.
How can organizations mitigate the risks associated with allocating common fixed costs?
Organizations can mitigate risks by carefully selecting allocation methods and criteria, ensuring that allocations are based on relevant and accurate data, and regularly reviewing and adjusting allocation methods as needed.
Are there alternative methods to allocating common fixed costs?
Yes, alternative methods include variable costing, direct costing, and segmented reporting, which can provide different perspectives on product profitability and cost allocation.
What are some best practices for allocating common fixed costs?
Best practices include using multiple allocation bases, considering activity-based costing, and employing the dual-rate method to enhance the accuracy and fairness of cost allocation.
