Understanding ABC Activity Based Costing

Activity-Based Costing (ABC) has emerged as an improvement to the traditional cost accounting system, offering advantages in the allocation of manufacturing overhead costs by focusing on the activities responsible for incurring these costs. To understand the full benefits of ABC, it is important to delve into its inception, development, and core principles.

The Genesis and Evolution of Activity-Based Costing

ABC was developed as a response to the shortcomings of traditional cost accounting systems, which typically allocated manufacturing overhead costs based on machine hours, leading to distorted and inaccurate cost representations. Companies with high overhead costs that did not directly correlate with production volumes, or those offering diverse product ranges and accommodating varying customer demands, necessitated a better approach to indirect cost allocation. As a result, the concept of ABC was born with the goal of providing a more accurate and logical foundation for assigning costs to activities that consume resources.

Defining Activity-Based Costing (ABC)

  1. Cost Accounting: ABC advances conventional cost accounting by allocating indirect costs based on the actual activities causing costs, rather than on arbitrary factors like machine hours.
  2. ABC inception: The advent of ABC reflects a focus on accurate cost representation and a departure from the inadequacies of traditional costing systems, driven by the evolving business landscape and resource-intensive production processes.
  3. Manufacturing Overhead Costs: ABC apportions manufacturing overhead costs to products based on the specific activities and resources they require, resulting in a more precise indirect cost allocation.
  4. Indirect Cost Allocation: By attributing costs to activities that consume resources, ABC disperses indirect costs more logically and accurately than traditional methods, leading to a clearer understanding of a product’s true cost structure.

By concentrating on the causal relationships between costs, activities, and outputs, ABC offers an effective method for aligning resources with their respective cost drivers while providing invaluable insights to drive informed decision-making and financial management strategies.

Core Principles of ABC Activity Based Costing

At the heart of the ABC method lies the concept of activities serving as cost drivers. Cost drivers are events or units of work that have specific goals or objectives, such as machine setups or processing purchase orders. By understanding the activities that drive costs, businesses can allocate overhead costs more accurately and ultimately make better-informed financial decisions.

ABC relies on two distinct types of activity measures: transaction drivers and duration drivers. Transaction drivers measure the number of times an activity occurs, while duration drivers record the time taken to complete the activity. By employing these two measures, ABC moves away from traditional volume-based cost allocation methods and more accurately links indirect costs to varying levels of activity required by different products or services.

  1. Transaction drivers: These measure the frequency of activities and help businesses understand the number of times a specific cost driver occurs. Some common examples of transaction drivers include the number of machine setups and the number of purchase orders processed.
  2. Duration drivers: These measure the length of time an activity takes to complete and assist in calculating the efficiency of a specific cost driver. Examples of duration drivers include the time spent on machine maintenance or the time required for a quality inspection.

By focusing on activities and their corresponding cost drivers, ABC enables a more accurate overhead cost analysis and a more direct cost allocation method. This helps businesses better understand the true costs of their products and services, facilitating more informed decision-making and strategic planning.

Activity-Based Costing in Action: A Scenario

Now that we have understood the basic principles of Activity-Based Costing (ABC), let’s explore its application with a practical costing scenario. This will provide valuable insights into the process of cost drivers identification and how a comprehensive costing analysis can be performed using ABC.

Identifying Cost Drivers in ABC

Imagine a manufacturing company that incurs a significant electricity bill, mainly due to labor hours. In this case, labor hours become the cost drivers, as they directly impact the total electric bill. With the ABC method, cost drivers are identified to allocate costs accurately, enabling businesses to pinpoint the source of their overhead expenses.

Examples of Calculating Costs with ABC

To demonstrate the allocation of costs using ABC, let’s consider a scenario where the company has three major cost drivers: machine setup, labor hours, and utilities (electricity and water). The first step involves creating a table to organize the cost pools and cost drivers associated with each.

Cost Pool
Overhead Cost
Cost Driver
Machine Setup
Number of setups
Labor Hours
Wage hours
kWh and Liters

With the cost pools and drivers in place, the next step is to calculate the cost driver rates for each cost pool. This can be done by dividing the total overhead cost of each cost pool by the total number of cost drivers. These rates allow for cost allocation to products based on the resources they consume.

  1. Machine Setup: $20,000 / 200 setups = $100 per setup
  2. Labor Hours: $30,000 / 2,000 hours = $15 per wage hour
  3. Utilities: $10,000 / 5,000 kWh = $2 per kWh and $10,000 / 2,000 Liters = $5 per Liter

Finally, we can utilize these cost driver rates to allocate costs to each product based on the resources they use. This comprehensive costing analysis can help businesses identify where their costs are coming from and optimize their manufacturing process accordingly.

Calculating Costs: The ABC Activity Based Costing Formula

Implementing the ABC formula to calculate overhead costs and allocate indirect costs can significantly contribute to a company’s financial management strategy. The process involves several stages that lead to a more transparent and accurate understanding of product costs.

  1. Identify and categorize the activities required for product creation into cost pools with specific overhead costs.
  2. Link cost drivers to each cost pool.
  3. Divide the total overhead cost of each cost pool by the total cost drivers to determine the cost driver rate.
  4. Multiply the cost driver rate by the amount of the cost driver utilized to allocate costs to products.

Once these steps are completed, a nuanced view of product costs based on real resource usage is achieved. This detailed costing methodology ensures that your organization can make more informed decisions in cost reduction and revenue optimization.

For instance, let’s examine an example calculation of overhead costs in a manufacturing company:

Cost Pool
Overhead Cost (USD)
Cost Driver
Total Cost Drivers
Cost Driver Rate (USD per driver)
Machine Setup
Number of Setup Hours
Number of Inspections
Number of Packages

In this example, the total overhead costs are allocated based on the cost drivers specific to each cost pool. Using these cost driver rates, an accurate indirect costs calculation can be carried out to properly allocate overhead costs to each product, giving you a better understanding of the profitability of each product line and how to optimize your organization’s activities.
