Activity Based Costing Accounting Explained

An activity is an event, task, or unit of work with a specific purpose, whether it be designing products, setting up machines, operating machines, or distributing products. Therefore, activity-based costing considers all the potential activities instead of relying on just one variable (for example, labor hours or machine hours). Second, it creates new bases for assigning overhead costs to items such that costs are allocated based on the activities that generate costs instead of on volume measures, such as machine hours or direct labor costs. Nowadays production processes are far more complex where direct labour costs are insignificant as compared to total costs.

As such, ABC has predominantly been used to support strategic decisions such as pricing, outsourcing, identification and measurement of process improvement initiatives. As an activity-based costing example, consider Company ABC that has a $50,000 per year electricity bill. For the year, there were 2,500 labor hours worked, which in this example is the cost driver. Calculating https://activeanglesey.com/2015/06/index.html the cost driver rate is done by dividing the $50,000 a year electric bill by the 2,500 hours, yielding a cost driver rate of $20. Activity-based costing is a method used to allocate overhead production costs. The ABC system breaks down manufacturing overhead into cost pools such as machines, raw materials, salaries, utilities and anything else that costs money.

What is Activity Based Costing (ABC)?

Each cost pool is then filled with individual cost objects (items) like electric, water, gas and all the rest that goes into making a product. Activity-based costing focuses on identifying the activities required to make products, on forming cost pools for each activity, and on allocating overhead costs to the products based on their use of each activity. ABC does not confined itself to the allocation to indirect costs to departments as it is done in the conventional costing but it identifies individual activity as the lowest unit for indirect cost allocation. Costs allocated to each activity represent the resources consumed by it. Unlike the traditional costing method, which allocates overhead costs based on broad categories, the ABC system offers a more accurate understanding of how you use resources and incur different types of costs.

• Therefore, there is no reason to assign any cost in an arbitrary manner.
• By understanding which activities drive the most costs, you can identify areas to improve efficiency and reduce waste.
• For example, the procurement or purchase of materials is made on the basis of a requisition note sent by a manufacturing department or stores.
• Cost-benefit analysis of each and every activity may be undertaken to judge the worthiness of activity.
• Kaplan (1998) suggested that scholars should wait before assessing the effect of ABC.

The cost per setup is calculated to be $500 ($200,000 of cost per year divided by 400 setups per year). Under http://www.mariabueno.org/indextemp.php/trousseau-davis-cup-and-rolex-frattina/, $200,000 of the overhead will be viewed as a batch-level cost. This means that $200,000 will first be allocated to batches of products to be manufactured (referred to as a Stage 1 allocation), and then be assigned to the units of product in each batch (referred to as Stage 2 allocation). For example, if Batch X consists of 5,000 units of product, the setup cost per unit is $0.10 ($500 divided by 5,000 units). If Batch Y is 50,000 units, the cost per unit for setup will be $0.01 ($500 divided by 50,000 units). For simplicity, let’s assume that the remaining $1,800,000 of manufacturing overhead is caused by the production activities that correlate with the company’s 100,000 machine hours.

Instead of using one plantwide overhead rate to allocate (or apply) overhead to products, an ABC system uses several overhead rates to allocate overhead. 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. Consequently, the use of arbitrary bases for apportionment and absorption of overhead expenses to different departments and by different products distorts the cost amounts attributable to the products. He opined, the traditional managerial accounting is at best useless, and at worst dysfunctional and misleading. 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.

However, simplicity does not justify the production and use of information that might be wrong or misleading. Step 4 then requires us to use the costs per unit of cost driver to absorb costs into each product based on how much the product uses of the driver. The cost pool for the purchasing materials activity will include costs for items such as salaries of purchasing personnel, rent for purchasing department office space, and depreciation of purchasing office equipment. ABC systems and traditional systems often result in vastly different product costs.

There are definitely advantages to running ABC systems over more traditional costing methods. Manufacturing companies that use activity-costing systems alongside lean management systems can see reduced waste, time saved and increased profits. Of course, implementing this system will take time and money to maintain, but the pros of ABC certainly outweigh the cons. By using an activity-based costing system, you can paint a better picture of where company finances are going and what your total cost drivers are. Digging deep into each product you make by looking at the tools and resources used during production and their costs can help you better plan your finances. These developments in manufacturing and marketing mean that the conventional way of treating fixed overheads might not be good enough.

• This lack of accuracy has led cost accountants to search for new, fairer ways to charge production units for their share of indirect expenses.
• Cost of activity will be charged to the product using cost driver rate according to the requirement of activities of each product.
• Hence, there is a need for more systematic and accurate system for cost ascertainment and cost control.

An ABC system can sort through these additional overhead costs and help you determine which customers are actually earning you a reasonable profit. This analysis may result in some unprofitable customers being turned away, or more emphasis http://www.hipergroup.com/page.php?id=148 being placed on those customers who are earning the company its largest profits. Create cost pools for those costs incurred to provide services to other parts of the company, rather than directly supporting a company’s products or services.
