Cost allocation is the process that includes identification, aggregation, and a sum of the cost assigning the cost to some cost object.
The cost object can be anything for which the business wants to know the cost incurred. It may be some project, product, activity, department, region, location, or any other object.
The business needs to allocate the cost to different cost objects to measure and analyze the cost. An appropriate allocation of the cost to the cost objects enables a business to identify if a certain cost object (product/project) is making losses or profits for the company. Let’s discuss different types of the cost with perspective to allocation.
Direct cost allocation
Direct cost can be allocated to the specific cost object under consideration. It does not need to be allocated as the entire cost is related to the same cost object.
For instance, the wages paid to direct workers on the plant producing product-A can be entirely allocated to product-A. Hence, there is no need to allocate the cost.
The concept of allocation arises when the cost objects share cost drivers. In other words, the cost same cost is shared by different cost objects.
Indirect cost is the cost that is incurred to facilitate the production but can not be traced directly with the cost object.
Consider a machine that is used for manufacturing multiple products, this machine requires periodic repairs, maintenance, cleaning, and other related expenses.
It is clear that the machine is used for manufacturing different products. Hence, the cost is allocated among different products by identifying the number of units produced for each product.
Overheads are the supportive cost for the production. These costs can not be directly allocated to the units manufactured.
For instance, the canteen department of the company serves employees of different departments like sales, production, accounting, and operations.
The cost of the canteen department needs to be allocated to these departments as the company’s canteen does not earn revenue as it’s just a cost center.
So, the cost of the canteen department can be allocated based on the number of employees in each of the departments.
Steps of cost allocation
Following are the steps of cost allocation for the cost object. The complexity of the allocation process increases with an increase in the cost drivers and basis of allocation.
1- Cost identification
Cost identification is the process of identifying all the costs associated with the cost driver. It’s a manual exercise that requires managers to closely observe the process for the manufacturing. So, all the costs associated with the cost object can be identified.
2- Identify the basis of allocation
An appropriate basis of allocation helps to fairly allocate the overheads between different cost objects. For instance, the overhead cost related to machines can be allocated based on the machine hours.
Similarly, the overhead cost for production in a labor-intensive environment can be allocated based on the number of hours.
3- Cost allocation
This is the stage of allocating the identified cost based on the identified allocation base. If the portion of allocation is higher for a specific cost object, the amount of the cost allocated will be higher and vice versa.
Examples of cost allocation
- The periodic depreciation expense of the production facility is allocated to the different products produced in the period under consideration.
- The cost of electricity is allocated among different departments of the company. The allocation basis may be square fit occupancy of the departments or some other appropriate basis depending on the usage of the electricity.
- The salary of the CFO can be allocated among different functions/departments of the business.
The basic purpose of the cost allocation is to bring transparency between different cost objects of the company. It helps to understand which cost object consumes more benefit brought by the cost driver and allocates the cost.
Hence, allocating the cost based on usage brings transparency. This helps to improve overall reporting as well.
2- Decision making
The cost allocation helps to identify the total cost of the cost objeclt like department, project, or product, etc. It helps to identify which cost object consumes more proportion of the funds.
Hence, knowing what product or department is taking a greater proportion of funds is important for weighing alternatives and making a decision on which cost object should be given priority.
Although, related revenue brought by the cost object needs to be considered before making any final decision for the extension/closure of the cost object.
3- Waste reduction
The cost allocation enables us to identify the potential wastage of the organizational resources. For instance, if the allocated cost of the stationary is higher for the accounting department than other departments, the business needs to analyze If the accounting department is using stationary for business purposes or if there is any wastage.
4- Enhanced reporting
The allocation process helps to get the valuation for the different items of the finished goods and work in process.
These items are reported in the financial statement. Hence, managers might not be able to report valuation for the inventory without using cost allocation.
The process of cost allocation can be difficult in the real world. There may be gretar number of the cost drivers and cost pools that need to be allocated.
Further, the process of the alloction requires selection of the basis for allocation. This can be really complex and judgmental.
Traditional vs ABC system of cost allocation
The main difference between ABC costing and traditional system of the allocation is bases for the allocation.
ABC system of allocation considers different basis of allocation for the different cost drivers. Oon the contrary, the trandtional system of allocation uses singl basis which may be not accurate.
ABC system is considered to be more fair and transparent considering the fair bases for the allocation of the cost.
On the contrary, the traditional system of the cost allocation is considered to be arbitrated method of cost allocation.
