What is the Difference Between Absorption Costing and Activity Based Costing?

🆚 Go to Comparative Table 🆚

Absorption costing and activity-based costing are two different methods used to allocate costs to products in cost accounting. The main differences between these two methods are:

  1. Approach: Absorption costing assigns costs to individual units, while activity-based costing focuses on company activities as a central cost and then attempts to assign indirect costs to units.
  2. Allocation: Absorption costing uses a single base to allocate all costs, whereas activity-based costing uses multiple cost bases for cost allocation.
  3. Time Consumption and Accuracy: Absorption costing is less time-consuming and less accurate, while activity-based costing is time-consuming but has increased accuracy.
  4. Usage and Popularity: Absorption costing is a traditional costing system and is widely used, while activity-based costing is a modern method of cost allocation and is preferred by many managers due to its nature and relevance of information.
  5. Implementation: Traditional costing is easy to implement and is the most common costing method used, whereas activity-based costing can be extremely complicated and difficult to implement.

In summary, absorption costing is a simpler and more widely used method for allocating costs, while activity-based costing provides a more accurate and detailed picture of costs but can be more complex and time-consuming to implement.

Comparative Table: Absorption Costing vs Activity Based Costing

The main differences between Absorption Costing and Activity-Based Costing are as follows:

Feature Absorption Costing Activity-Based Costing
Method Assigns costs to individual units based on a single cost base Focuses on company activities as a central cost, then assigns costs to individual units using multiple cost bases
Time Period Less time-consuming and less accurate More time-consuming but has increased accuracy
Usage and Popularity Traditional costing system, less popular Modern method of cost accounting, gaining fast popularity
Allocation of Overhead Costs Allocates fixed overhead costs to each unit of product Allocates overhead costs based on various resources used to make the product
Orientation Cost-driven Process-driven

Absorption costing is a traditional method that assigns costs to individual units based on a single cost base, such as direct labor or machine hours. It is less time-consuming and less accurate compared to activity-based costing. This method is more suitable when direct labor is a large portion of the product cost.

On the other hand, activity-based costing is a modern method that focuses on company activities as a central cost and then assigns costs to individual units using multiple cost bases. It is more time-consuming and costly to implement but provides increased accuracy. This method is more suitable when technology is a large portion of the product cost.
