Why is direct labor a poor base for allocating overhead in many companies? Direct labor is often replaced by machines; and decrease in direct labor leads to an increase in overhead. Overhead costs are driven by factors such as product diversity and complexity as well as volume.
When activity-based costing is used for internal decision-making the costs of idle capacity should be assigned to products?
The costs of idle capacity should be assigned to products in activity-based costing. In activity-based costing, some manufacturing costs can be excluded from product costs. Batch-level activities are performed each time a unit is produced.
What costs are not assigned to products?
Period costs are all costs not included in product costs. Period costs are not directly tied to the production process. Overhead or sales, general, and administrative (SG&A) costs are considered period costs.
What types of costs should not be assigned to products in an activity-based costing system explain?
What types of costs should not be assigned to products in an activity-based costing system? Organization-sustaining costs, customer-level costs, and the costs of idle capacity should not be assigned to products.
Which of the following is a limitation of activity-based costing?
(4) Difficult to evaluate cost on the basis of activities. The choice of both activities and cost drivers might be inappropriate. Activity-based costing data may easily be misinterpreted and so it should be handled with care when used in making decisions. (5) Not suitable for small manufacturing concerns.
What are the two stages of the allocation of overhead costs in Activity-Based Costing?
The first stage of allocation determines the cost of each occurrence of an overhead event during the process. The second stage allocates the cost of each occurrence to individual items produced by the business.
When activity-based costing is used for internal decision-making?
When activity-based costing is used for internal decision-making, the costs of idle capacity should be assigned to products. Direct labor costs are usually included in the costs that are allocated to activity cost pools in an activity-based costing system.
What are some of the limitations of activity-based costing systems?
Disadvantages of Activity-Based Costing Collection and preparation of data is time-consuming. Costs more to accumulate and analyze information. Source data isn’t always readily available from normal accounting reports.
What causes traditional and activity-based costing systems?
What causes traditional and activity-based costing systems to report different product margins? Traditional cost systems allocate all manufacturing overhead costs to products. The ABC system assigns nonmanufacturing overhead costs to products on a cause-and-effect basis as appropriate.
Which stage in activity-based costing uses activity rates to apply overhead costs to products?
Activity rates are used to apply overhead costs to products and customers in the (1)-stage allocation.
What are the benefits of Activity-Based Costing?
Activity-based costing provides a more accurate method of product/service costing, leading to more accurate pricing decisions. It increases understanding of overheads and cost drivers; and makes costly and non-value adding activities more visible, allowing managers to reduce or eliminate them.
What’s the difference between activity-based costing and traditional?
The differences are in the accuracy and complexity of the two methods. Traditional costing is more simplistic and less accurate than ABC, and typically assigns overhead costs to products based on an arbitrary average rate. ABC is more complex and more accurate than traditional costing.
What is Activity Based Costing what are its advantages and limitations?
What are the stages of activity-based costing?
The five steps are as follows:
- Identify costly activities required to complete products.
- Assign overhead costs to the activities identified in step 1.
- Identify the cost driver for each activity.
- Calculate a predetermined overhead rate for each activity.
- Allocate overhead costs to products.
Why would an activity-based costing system that is designed for internal decision making?
An activity-based costing system that is designed for internal decision-making will not conform to generally accepted accounting principles because: some manufacturing costs (i.e., the costs of idle capacity and organization-sustaining costs) will not be assigned to products.
What is the benefit of activity-based costing?
What is a limitation of ABC?
Disadvantages of ABC: It is impossible to allocate all overhead costs to specific activities. The choice of both activities and cost drivers might be inappropriate. ABC can be more complex to explain to the stakeholders of the costing exercise. The benefits obtained from ABC might not justify the costs.
