Activity-based costing definition

What is activity based costing

An activity-based costing system (also known as ABC System) is a two-stage procedure for assigning overhead costs to products, which focuses on the major activities performed in the production process. However, as the percentages of indirect or overhead costs rose, this technique became increasingly inaccurate, because indirect costs were not caused equally by all products. Consequently, when multiple products share common costs, there is a danger of one product subsidizing another.

For instance, a manager may aim at reducing cost of transporting the product from Rs. 5 per unit to Rs. 4.50 per unit. Use existing accounting and financial data, which includes labour and capital equipment expenses and any other resource that can be changed or eliminated. Some reports to analyse include budget, general ledger, supplier invoices.

What is activity based costing

Beyond such selective application of the concept, ABC may be extended to accounting, hence proliferating a full scope of cost generation in departments or along product manufacturing. Such extension, however requires a degree of automatic data capture that prevents from cost increase in administering costs. However, application of an activity based recording may be applied as an addition to activity based accounting, not as a replacement of any costing model, but to transform concurrent process accounting into a more authentic approach. Core activities—or the organization’s primary activities—are those with high costs and play an important role in relation to the activity’s total cost. The cost structure is always changing, and as indirect costs increasingly take up a larger slice of the pie.

Activity-Based Costing (ABC): Method and Advantages Defined with Example

Activity-based costing is used to get a better grasp on costs, allowing companies to form a more appropriate pricing strategy. A major advantage of using Activity based costing (ABC) is that it avoids or minimizes distortions in product costing that result from arbitrary allocations of indirect costs. Using ABC, overhead costs are traced to products and services by identifying the resources, activities and their costs and quantities to produce output. Workflows have become more automated through technological advancements and machine learning instead of labor-dependent. Additionally, products have become more unique and specialized as markets have become more saturated.

The state of the art approach with authentication and authorization in IETF standard RADIUS gives an easy solution for accounting all workposition based activities. That simply defines the extension of the Authentication and Authorization (AA) concept to a more advanced AA and Accounting (AAA) concept. Respective approaches for AAA get defined and staffed in the context of mobile services, when using smart phones as e.a.

Steps to Follow in Activity-Based Costing

Activity Based Management (ABM) differs from Activity Based Costing (ABC). Activity Based Costing (ABC) establishes relationship between overheads costs and activities in order to ensure that the overheads costs are more precisely allocated to products, services or customers segments. While Activity Based Management (ABM) focuses on managing activities, reducing costs and improving customer value. Identification of cost during activities and their causes not only help in computation of more accurate cost of a product or a job but also eliminate non-value added activities. The elimination of non-value added activities would drive down the cost of the product.

The potential problem with ABC, like other cost allocation approaches, is that it essentially treats fixed costs as if they were variable. This can, without proper understanding, give some people an inaccurate understanding which can then lead to poor decision making. For example, allocating PPE to individual products, may lead to discontinuation of products that seem unprofitable after the allocation, even if in fact their discontinuation will negatively affect the bottom line. Activity-based costing records the costs that traditional cost accounting does not do. More accurate information on the product’s cost provides more activity-based costing aimed at measurement and decision-making purposes.

  1. Applicability of ABC is bound to cost of required data capture.[1] That drives the prevalence to slow processes in services and administrations, where staff time consumed per task defines a dominant portion of cost.
  2. Conversely, it is of less use in a streamlined environment where production processes are abbreviated, so that costs are easy to assign.
  3. It may be noted that the technique of Activity Based Management should be used by management keeping in mind the fact that decision made should in the benefit of the whole organization and not only for a particular department or division.
  4. Generally, the scope of an ABC project should be kept fairly narrow, to make the project easier to manage and more cost-effective.
  5. An example of a cost pool could be the cost of a maintenance department or a quality control department.
  6. (b) It charges overhead cost to product according to activities involved in the product instead of using average overhead distribution rate as in case of traditional method.

Thus, in ABC, overhead cost is attributed to the cost centre or unit on the basis of number of activities undertaken in production. It uses activities as the basis for determining the costs of products or services. 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. This can lead to the reapportionment of production work to those facilities incurring lower overhead costs, and possibly the shut-down of unusually high-cost facilities. Convert the results of the ABC system into reports for management consumption. For example, if the system was originally designed to accumulate overhead information by geographical sales region, then report on revenues earned in each region, all direct costs, and the overhead derived from the ABC system.

Activity Based Costing – ABC Approach and Example of the Steps Needed to Develop ABC Data

Activity-based costing provides this structure and allows for a business to access a more accurate measurement for the cost of each unit they produce, be it material or a service. ABC provides more accurate and informative product costs which in turn help the management to take decisions about pricing, product lines and market segments. Nevertheless, since there are usually more activities than cost centers and often cost driver rates are more justifiable than the rates used by absorption costing, an ABC system, most of the times, produces more accurate results. 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. Cost of activity will be charged to the product using cost driver rate according to the requirement of activities of each product.

Identify Costs of Low-Volume Products

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. (d) Strategic cost information of which long-term profitability decision for a product can be taken. Therefore it is one of the effective methods of exercising cost control and can be used in designing either job costing system or process costing system. ABC is based on George Staubus Activity Costing and Input-Output Accounting.

ABC systems are notoriously difficult to install, with multi-year installations being the norm when a company attempts to install it across all product lines and facilities. For such comprehensive installations, it is difficult to maintain a high level of management and budgetary support as the months roll by without installation being completed. Success rates are much higher for smaller, more targeted ABC installations. When ABC is reportedly used in the public administration sector, the reported studies do not provide evidence about the success of methodology beyond justification of budgeting practise and existing service management and strategies. After this, we will identify a set of sub-activities with low costs compared to the activities’ basic or main costs. Indirect costs are the majority component of the cost structure; direct expenses, including salaries, account for a large proportion of it.

Integrating EVA and process based costing

Unit costing is used to calculate the cost of banking services by determining the cost and consumption of each unit of output of functions required to deliver the service. The basic feature of functional departments is that they tend to include a series of different activities causing different costs that behave in different ways. Thus, the activity based system system uses activities instead of functional departments (Cost Centers) for absorbing overheads. There is a simple, three-step method for calculating the cost-per-activity using activity-based costing.
