Activity Based Costing Formula

activity based costing steps

ABC is designed to track the cost of activities, so you can use it to see if activity costs are in line with industry standards. If not, ABC is an excellent feedback tool for measuring the ongoing cost of specific services as management focuses on cost reduction. To finally achieve activity costs, compute the number of hours/parts/units etc. used by the activity and multiply the same with the cost driver rate.

The cost structure is changing especially when making direct labour component to small proportion. The traditional fixed verses variable cost split is often unrealistic since, as business grows they often become more complex. Moving of production to other places, which will increase cost instead of decrease in costs.

They can also use it to manage product and process design. As allocations are broken down/determined, the use of resources becomes transparent from a process standpoint, allowing managers to improve operations as needed. A good example could be quality control wherein one could find out the very cost of quality control by counting the number of inspections made and the total what are retained earnings number of units produced. In the table given here, have been mentioned these two activities- cost pool and cost driver. Select the activities to use for assigning indirect costs to the products through using a cost-allocation base. Identify the indirect costs connected to each activity of the process. Activity-based costing helps you identify where you’re wasting money.

Identify The Total Costs

Use of resources for a batch-level activity is independent of number of units in the batch. Example of batch-level activity is setting up a machine for a new production run. Batch- level costs are independent of the number of units processed in the batch but vary with the number of production runs, the number of purchase orders, or the number of invoices. Thus, overheads are aggregated at the production cost centre level and are assigned to units produced. Assignment is based on average rate determined by dividing the overhead expenses by the volume of units produced or a surrogate for the same.

Those using ABC also had a higher level of automation. The complexity of production processes and products tended to be higher for those using ABC, and ABC companies operated at capacity more frequently.

However, in conventional costing the distribution of that total to individual products is based on an indirect measure of that cost. The activity-based formula simply gives us the dollar value of amount per activity which is then can be multiplied to determine the cost of the total products assigned or produced in that particular cost pool. By computing and using this method of activity-based costing the manufacturing company can successfully and more accurately determine the various product cost and hence can have a detailed cost analysis report.

Under the traditional budgeting method, the company will estimate the cost of goods sold in the upcoming month to be $4,400 [$4,000 + ($4,000 x 10%)]. On the other hand, a new start-up doesn’t have years of historical financial information at its disposal. It may be worthwhile for the newer start-up to inspect each cost driver and their corresponding activity levels to make more accurate financial projections. For example, a more established retail business, such as Walmart, has made changes to optimize its strategy for profitability over many years. Their profits are going to remain at a relatively even growth rate, and they know exactly what their cost drivers are.

Therefore cost drivers signify factors, forces or events that determine the costs of activities. The activity based cost information can be used to identify the products or activities which are useful for the organization.

The cost driver rates are required to be calculated on a suitable basis. Such costs are common to all the products manufactured. Overhead costs are no longer a mere burden to be minimised. Overhead functions such as product design, quality control, customer service, production planning and sales order processing are as important to the customer as physical processes on the shop floor.

Other Uses For Cost Allocation

ABC has been defined by CIMA as ‘cost attribution to cost units on the basis of benefit received from indirect activities e.g. ordering setting up, assuring quality’. According to Horngren, Foster and Datar ‘ABC is not an alternative costing system to job costing or process costing. Rather ABC is an approach to developing the cost numbers used in job costing or process costing systems. The distinctive feature of ABC is its focus on activities as the fundamental cost objects. In contrast most traditional approaches used in job and process costing systems rely on general purpose accounting systems, not tailored to the activities found in individual organisations. The ABC approach has the potential to provide managers with information they find more useful for costing purposes’. In traditional cost accounting (production volume-based allocation), an accurate measure of total overhead cost is accessible.

It helps in eliminating non-value added activities thereby reducing the per unit cost of product. It leads to more accurate cost information because of easy traceability of cost according activity based costing steps to activities cost driver. 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.

The cost information is normally reported too late to support improvement efforts and it is not reported by activity. The traditional approach is more suitable when the contribution of overhead costs to production costs is relatively small.

The departmental overhead rate is defined as an expense rate for every department in a factory production process. Cost accounting is a form of managerial accounting that aims to capture a company’s total cost of production by assessing its variable and fixed costs. 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. Increased knowledge of production activities leads to process improvements and reduced costs. ABC requires identifying the activities involved in the production process and assigning costs to these activities .

A single representative activity driver can be used to assign costs from the activity cost pools to cost objects. Such linking of total costs to cost objects is generally based on the activity driver rate. You won’t find such an approach in a traditional costing system.

A Unit

These pools will each have some contribution to object cost. ABC continues with activity analysis, clearly identifying the processes which support a product and avoiding some of the systemic inaccuracies of traditional costing.

Note that the purpose of ABC is to provide information for decision support and planning. ABC by itself usually has little or no impact on the structure of the firm’s financial accounting reports normal balance . This impact is minimal because both ABC and traditional costing ultimately assign costs to the same existing accounts. The two approaches merely use different mathematics to do so.

But in case of ABC, set up and adjustment time is determined for each department and its cost is directly charged to each department. Therefore ABC tries to ascertain the factors which are responsible for each major activity, costs of these activities and relationship between activities and products.

An average product manufacturing requires more than 3 to 4 processes. To deal complications in costing created due to processes, ABC is a blessing in disguise.

The manufacturing support activities such as ordering materials and its inspection constitute the batch level activities. A cost pool including costs to entertain clients and make sales calls is a ______ activity. ABB provides stronger links between an organization’s strategic objectives and the objectives of the individual activities within a business for which departmental managers are responsible. Additionally, important strength of ABB is its ability to tackle cross-organizational issues by a participative approach and activity analysis techniques, all of which promote continuous improvement. Some costs are incurred at production level for the whole of the batch rather than for individual products. Some costs are incurred primarily in relation to production process and relationship can be established with the number of units produced. In product costing applications, ABC allows costs to be apportioned to products by the actual activities and resources consumed in producing marketing, selling, delivering and servicing the product.

However, since both methods make assumptions about the behaviour and cause of costs, it cannot be said with certainty that ABC shall always produce more precise results than traditional costing. A cost pool is a collection of overhead costs that are logically related to the tasks being performed.

Therefore, in order to trace overhead costs to products or services, appropriate cost drivers should be identified. A cost driver is taken as on activity which generates cost. After identifying the overhead cost with each cost centre, the cost per unit of cost driver can be ascertained and cost assigned to jobs on the basis of number of activities required for their accomplishment. Thus, ABC serves as a basis for product costing besides aiming for managing overhead cost. Activity based costing is a method of cost attribution to cost units on the basis of benefits received from indirect activities. Since no correlation is seen between direct labor and overhead costs incurred, predetermined overhead rates based on direct labor are used, which is inappropriate.

Abc Vs Traditional Costing, Results Compared

Better Reporting – ABC system provides better reporting of cost of activities and their performance which will help in taking suitable decision and in 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.

  • It is also easy to allocate costs for each process as they are all taken separately and account for only a small part of the whole production process.
  • Managers also explore the possibility of doing value-added and non-value-added essential activities more efficiently by simplifying the internal process.
  • Examples of duration drivers are set-up hours and inspection hours.
  • It can be quite difficult to maintain this extra database, since it calls for significant extra staff time for which there may not be an adequate budget.
  • ABC recognizes the cost behaviour and identifies the value added and non-value added activities.
  • Managers are more likely to focus on improving efficiency in the most costly activities, thereby reducing costs.

There has been a significant increase in indirect costs with the advent of technology. Against the only cost i.e. labor, there are fixed costs of machinery replacing the labor cost. Technical hitches due to the introduction of sophisticated machineries have increased. With the growth and development of industry and business, the complications in the processes of manufacturing or providing services have increased significantly.

More Accurate Product Pricing

The culmination of that thought is an accurate per unit calculation of profitability. Here, you will fill in the Metrics data for each product based on the Activities entered in the Identify Activities section of the Activity Information worksheet. Since activity-based costing is, by its nature, more accurate. The costs do match in the Spreadsheets for Business Operating Budget Workbook and this ABC workbook. The hypothetical company is assumed to have only five products . Try to keep the percentages entered into the Unallocated column to a minimum.

The more in Sales units a product has, the less the impact of unallocated costs. The temptation might be to burden the high volume products with the unallocated costs– since they’re the ones that can bear it. Item margin per unit reflects the gross profitability of each item.
