What Is The Primary Benefit Of Activity Based Costing?

limitations of activity based costing

A limited number of cost drivers may not fully explain the cost behavior of different items in the cost pool. In some cases finding the activity that causes the cost is impractical. For example, factory insurances, factory manager’s salary, rent, rates and taxes of the factory premises. In these cases, it is better to allocate costs on the basis of arbitrary volume. Accuracy in Product Cost – ABC system ascertains accurate product cost due to better understanding of the cost behaviour. Of course the apportionment of indirect cost to cost objectives is required. This is a continuous improvement process in terms of analysing the cost, to reduce or eliminate the non-value-added activities and to achieve an overall efficiency.

  • It can be considered as the modern alternative to absorption costing, allowing managers to better understand product and customer net profitability.
  • On the other hand, they underscore the importance to consider the cost of capital in order to bring strategy back into performance measures.
  • The gas dispensing pool included costs for storage tanks, all of which were the same size, as well as gas pumps and signs.
  • Strategic cost information of which long-term profitability decision for a product can be taken.
  • As you can see in Figure 3.6 “SailRite Company Product Costs Using Activity-Based Costing”, overhead is a significant component of total product costs.
  • Technical hitches due to the introduction of sophisticated machineries have increased.

Since product pricing is based on total costs, having a good understanding of manufacturing costs will result in better product pricing and, therefore, higher profits. These levels include batch-level activity, unit-level activity, customer-level activity, organization-sustaining activity, and product-level activity. Activity-based costing is a costing method that assigns overhead and indirect costs to related products and services. This accounting method of costing recognizes the relationship between costs, overhead activities, and manufactured products, assigning indirect costs to products less arbitrarily than traditional costing methods. However, some indirect costs, such as management and office staff salaries, are difficult to assign to a product. Mr. Birch must determine if the benefits of implementing ABC outweigh the limitations.

In conclusion, it is significant to keep in mind that the goals should be met at the minimum cost and difficulty in order to intend an activity based costing system. To be successful, the last activity based costing system should give the right type of information at the right level of detail. In addition to this the design of the system should be as simple as feasible without being too easy since it may report inaccurate costs if it is too easy. The answer is to strike a balance between simplicity and difficulty. In addition to this, performance calculates should be recognized at procedure level and for key activities.

Likewise, when assessing the costs of products and services, ABC can illustrate the costs of them and help in establishing the profitability of the individual products and services. This can be particularly useful in modern economies where companies are increasingly trying to differentiate and personalise both products and services and tailor them to individual needs and requirements. Management of overhead cost is achieved by coupling the costs to the activities that ‘drive’ or ’cause’ them. That means, overhead expenses are initially identified with the cost centres (i.e., departments, divisions, branches, etc.) and then, they are identified with, and charged to, the products. It may be noted here that the prime costs are identified with, and charged directly to, the products.

Activity-based costing enhances the costing process in three ways. First, it expands the number of cost pools that can be used to assemble overhead costs. Instead of accumulating all costs in one company-wide pool, it pools costs by activity. Assign each cost pool activity cost drivers, such as hours or units. ABC focuses attention on cost drivers, the activities that cause costs to increase. Traditional absorption costing tends to focus on volume-related drivers, such as labour hours, while activity-based costing also uses transaction-based drivers, such as number of orders received.

Just take the total cost of each cost pool and divide it by the overall activity in the activity driver. You can now allocate the cost per unit to the cost objects based on the usage by the activity driver. Activity-Based Costing is used to a greater degree in the manufacturing industry as it helps to improve the reliability of cost data. It allows a firm to create viable pricing strategies that prove fruitful for them.

This step will help to convert the results that you have derived from the Activity Based Costing process into reports. These are specially meant for the management and will provide a full cost view of the results. It acknowledges the relationship between costs, manufactured products and overhead activities. ABC costing system does not comply with the GAAP and a company has to produce its reports for internal and external purposes by using traditional and ABC costing system both at a time. Compared with the plantwide approach, activity-based costing showed a lower cost per gallon for regular gas and a higher cost per gallon for the other two grades of fuel. Once the ABC information was presented, the case was settled, and the initial injunction was lifted.

Reports generated by this systems do not conform to generally accepted accounting principles . Consequently, an organization involved in activity based costing should have two cost systems – one for internal use and one for preparing external reports. Figure 3.9 “The Three Methods of Overhead Allocation” presents the three allocation methods, using SailRite as an example. Notice that the three pie charts in the illustration are of equal size, representing the $8,000,000 total overhead costs incurred by SailRite.

These activities are common to a variety of products and are most difficult to produce specific activities. It is usually quite easy to segregate overhead costs at the plant-wide level, so you can compare the costs of production between different facilities. ABC can be difficult and time-consuming to collect data about activities and cost drivers. Activity Based Costing is used to sort overhead costs at the plant itself.

Demerits Of Activity Based Costing Abc:

The ABC system will require a change due to changes associated with new products and new technology. This will put strain on the costing system and resources due to certain degree of inbuilt standardisation. Better Reporting – ABC system provides better reporting of cost of activities and their performance which will help in taking suitable decision and in cash flow improving efficiency. ABC helps managers to identify and control the cost of unused capacity. ABC has also enabled enterprises to model the impact of cost reduction and subsequently confirm the savings achieved. With ABC, any enterprise will have a built-in competitive cost advantage and can continuously add value to both its stakeholders and customers.

Notice that the total activity levels presented here match the estimated activity levels presented in step 4. This was done to avoid complicating the example with overapplied and underapplied overhead. However, a more realistic scenario would provide actual activity levels that are different than estimated activity levels, thereby creating overapplied and underapplied overhead for each activity. We described the disposition of overapplied and underapplied overhead in Chapter 2 “How Is Job Costing Used to Track Production Costs?”. Managerial Accounting has equal application in the service and manufacturing industry as well. There are three major an aspect for which managerial accounting is widely used.

Cost signify factors, forces or events that determine the costs of activities. Cost drivers are the links and they can link a pool of costs in an activity centre to a product.

Its use leads to better product pricing since the underlying cost to manufacture a product is more accurate. For example, using an ABC system, Mr. Birch may determine that it costs $250 to manufacture a coffee table, but he is only charging customers $260. Having better cost information would allow limitations of activity based costing Mr. Birch to adjust the price of the coffee table to ensure he’s making more profit. Activity-based costing system is a method of accounting you can use to find the total cost of activities necessary to make a product. The ABC system assigns costs to each activity that goes into production.

However, the circuit board for the aeroplane is tested for a longer time by highly paid technicians because it must be 100% error-free. Once processes are re-engineered, then the new costs must be tabulated.

Selecting Appropriate Cost Drivers

Setting-up of an information system which could help trace all the costs to cost objects. Cost are pooled not on the basis of departments but according to the activities involved in the production. Volume or quantity of production is not primary driving force for the consumption of overhead resources. Identify activities and drivers – Determine what drives what activity. Lean accounting methods have been developed in recent years to provide relevant and thorough accounting, control, and measurement systems without the complex and costly methods of manually driven ABC.

CIMA, the Chartered Institute of Management Accountants, defines ABC as an approach to the costing and monitoring of activities which involves tracing resource consumption and costing final outputs. Resources are assigned to activities, and activities to cost objects based on consumption estimates. The latter utilize cost drivers to attach activity costs to outputs. Using cost drivers also allows a company to identify business processes that are performing well and those that are not.


The term applied overhead is often used to describe this process. Activity based costing assigns manufacturing overhead costs to products in a more logical manner than the traditional approach of simply allocating costs on the basis of machine hours. Activity based costing first assigns costs to the activities that are the real cause of the overhead. Activity based costing is an accounting methodology that assigns costs to activities rather than products or services. This enables resources and overhead costs to be more accurately assigned to the products and the services that consume them. ABC is a systematic, cause-and-effect method of assigning the cost of activities of products, services, customers, or any cost object.

Activity-based costing simply provides a more refined way to allocate the same overhead costs to products. It improves product costing procedure as compared to traditional costing because it recognizes that many so called fixed overhead costs change in proportion to changes other than the production units. It means, under ABC, the other two activities-batch level and product level are assumed to influence fixed overhead costs and batch and product level, thus are accepted as non-unit based cost drivers. An effective cost accumulation system is required to generate relevant cost information for decision making.

Comparison Between Npv And Irr Method:

A wise manager will not focus on how to estimate product costs, but will focus more on why the costs were there in the first place. When intending an activity based costing system this should be utilized as a departure point. Job order costing or job costing is a system for assigning and accumulating manufacturing costs of an individual unit of output. The job order costing system is used when the various items produced are sufficiently different from each other and each has a significant cost.

What Are The Advantages And Disadvantages Of Job Order Costing?

The costs are grouped into cost pools and linked to a cost driver to develop a rate, which is then used to allocate overhead costs. Direct labour and materials are relatively easy to trace directly to products, but it is more difficult to directly allocate indirect costs to products.

Finally, the overhead costs of activities are charged to the products produced, and the product costs are ascertained more accurately. ABC technique provides due importance to non-manufacturing income summary cost which constitutes a substantial portion of total cost. Traditionally non-manufacturing costs have been allocated under volume basis and thus, high volume products have been overvalued.

This means that the data is far off compared to traditional costing systems. What are three advantages of activity-based costing bookkeeping over traditional volume-based allocation methods? Ease of use, more accurate product costing, and more effective cost control.

Where selling prices are fixed on the basis of cost plus formula, ABC provides more reliable data for fixing selling prices. It may become apparent that costs are not driven solely by output volumes, and, therefore the focus on managerial attention may be significantly broadened. This may encourage managers to adopt a holistic view of the organization. Accurate product cost due to understanding of the cost behaviour. Different products are using different activities and consume different resources.
