Chapter Outline
I. Plantwide Overhead Rate Method
A. Cost Flows under Plantwide Overhead Rate Method
1. Uses one overhead rate to allocate overhead costs to products.
3. The rate is determined using volume related measure, such as
direct labor hours, machine hours, or direct labor cost dollars.
B. Applying the Plantwide Overhead Rate Method
1. Total budgeted overhead costs are combined into one cost pool
2. The cost pool is divided by the selected allocation base (direct
3. The rate is then applied to assign costs to all products based on
the allocation base such as direct labor hours or machine hours
required to manufacture each product.
II. Activity-Based Costing
A. Cost Flows under Activity-Based Costing
1. Attempts to better allocate overhead costs to proper users of
overhead activities by focusing on activities.
2. Activity-based costing flows three steps:
3. a. Identify activities and assign costs to activity cost pools.
5. First Step:
a. Identify activities involved in processing the product or
service and then form activity cost pools by combining
6. Second Step:
a. Activity rates are computed as follows:

B. Advantages and Disadvantages of Activity-Based Costing
1. ABC uses more allocation bases than a traditional cost system
2. ABC is very effective when the same department produces
many different types of products. More complex products
3. ABC encourages managers to focus on activities and the use of
those activities.
4. ABC helps managers identify the activities which cause costs
5. ABC requires managers to look at each item and encourages
them to manage each cost to increase the benefit from each
6. ABC requires more effort to implement and maintain than a

Appendix C Alternate Demonstration Problem
Plata Company manufacturers 2 printer models: Deluxe and Cheapie. A single
plantwide cost driver (150% of direct labor cost) is used to apply the $24,000 of
overhead costs to the products. The following information is available:
Deluxe
Cheapie
Quantity to be produced

1. Using the plantwide overhead rate method, compute the cost per unit, the
gross profit per unit and gross profit rate per unit.
The company decided to apply the activity based costing (ABC) method to see if they
can get a better allocation of overhead costs. The following data was collected:
