The ABC (Activity-Based Costing) technique is a method used in managerial accounting to determine the cost of specific activities and allocate costs to products or services based on the resources they consume. It identifies activities that drive costs, estimates the costs driven by each activity, and states them as averages per unit of activity. This allows managers to understand the true costs of their products and make informed decisions to reduce costs and improve profitability.
What is Activity-Based Costing (ABC)?
Activity-based costing (ABC) is a cost-finding method grounded in the principle that activities drive costs within an organization. Unlike traditional costing methods that allocate costs based on volume, ABC focuses on identifying and assigning costs to specific activities, providing a more accurate picture of resource consumption.
How Does Activity-Based Costing Work?
The ABC technique involves several key steps:
- Identify Activities: Determine the specific activities that drive costs within the organization.
- Estimate Costs: Estimate the costs associated with each activity.
- Calculate Activity Rates: Calculate the average cost per unit of activity.
- Assign Costs: Assign costs to products or services based on their consumption of activities.
For example, machine hours averaging $12 per hour, production batches averaging $100 per batch, and material maintenance averaging $100 a year for each component part used. Therefore, a product assembled from six component parts incurs annual maintenance costs of 6 × $100 = $600, regardless of volume.
What are the Benefits of Using ABC?
- More Accurate Costing: ABC provides a more accurate understanding of the true costs of products and services.
- Better Decision Making: By understanding the drivers of costs, managers can make more informed decisions about pricing, product mix, and process improvements.
- Improved Cost Control: ABC helps identify areas where costs can be reduced or eliminated.
Activity-Based Costing vs. Traditional Costing Methods
Traditional costing methods, such as process costing and job-order costing, often allocate overhead costs based on volume-related measures like direct labor hours or machine hours. ABC, on the other hand, recognizes that many costs are driven by factors other than volume.

What are Some Examples of ABC Implementation?
For instance, consider a manufacturing plant with machine hours averaging $12 per hour and production batches costing $100 each. If a product requires 15 machine hours per batch of 1,000 units, the machine-driven costs average 15 × $12/1,000 = $0.18 per unit.
How Can ABC Improve Business Profitability?
By providing a more accurate understanding of costs, ABC enables businesses to identify areas for improvement and cost reduction. This can lead to increased efficiency, better pricing strategies, and ultimately, improved profitability.
In summary, the ABC technique is a valuable tool for businesses seeking to gain a deeper understanding of their costs and improve their decision-making processes. By focusing on activities and their associated costs, ABC provides a more accurate and
