Objectives 1. Identify three methods used for After studying this costs to allocating factory overhead products. chapter, you should be able to: 2. Use a single plantwide factory overhead rate for product costing. 3. Use multiple production department factory overhead rates for product costing. 4. Use activity-based costing for product costing.

Objectives 5. Use activity-based costing to allocate selling and administrative expenses to products. 6. Use activity-based costing in a service business.

Product Costing Allocation Methods Plantwide Overhead Rate Single Rate Multiple Department Rates Department Activity-Based Costing Activity P R O D U C T S

Single Plantwide Factory Overhead Rate

Computing Single Plantwide Factory Overhead Total budgeted factory overhead costs Total budgeted plantwide allocation base $1, 600, 000 $80 per hour = overhead rate 20, 000 direct labor hours

Computing Single Plantwide Factory Overhead Snowmobile: $80 per dlh x 10 direct labor hours = $800 Lawnmower: $80 per dlh x 10 direct labor hours = $800 Factory Overhead cost per unit

Plantwide factory overhead $1, 600, 000 $80 per direct labor hour x 10 direct labor hours Snowmobile $800 per unit x 10 direct labor hours Lawnmower $800 per unit

The greatest advantage of the single plantwide overhead rate is that it is simple and inexpensive to apply.

Production Department Factory Overhead Rates and Allocation Fabrication Department Overhead Rate: $1, 030, 000 10, 000 direct labor hours = $103 per hour Assembly Department Overhead Rate: $570, 000 10, 000 direct labor hours = $57 per hour

Production Department Factory Overhead Rates and Allocation Snowmobile: Fabrication: $103 x 8 dlh = $824 Assembly: $57 x 2 dlh = 114 $938 Lawnmower: Fabrication: $103 x 2 dlh = $206 Assembly: $57 x 8 dlh = 456 $662

Multiple Production Department Rate Method—Ruiz Company Fabrication Department $1, 030, 000 $103 x 8 dlh $938 per unit Assembly Department $570, 000 $57 x 2 dlh

Multiple Production Department Rate Method—Ruiz Company Fabrication Department $1, 030, 000 Assembly Department $570, 000 $103 x 2 dlh $57 x 8 dlh $662 per unit

Distortion in Product Costs—Single Plantwide versus Multiple Production Department Overhead Rates Factory Overhead Cost per Unit Single Plantwide Rate Snowmobile Lawnmower $800 Multiple Production Department Rates $938 662

Distortion in Product Costs—Single Plantwide versus Multiple Production Department Overhead Rates The single plantwide factory overhead rate distorts product cost by averaging high and low factory overhead costs.

Conditions for Product Cost Distortion—Ruiz Company Fabrication Department Condition 1: Differences in production department factory overhead rates $103 per direct labor hour Continued Assembly Department $57 per direct labor hour

Conditions for Product Cost Distortion—Ruiz Company Condition 2: Differences in the ratios of allocation-base usage 8 direct labor hours 2 direct labor hours 8 direct labor hours

Activity-Based Costing Method 1. Activity-based costing changes the way overhead costs are allocated. 2. When identifying specific activities, inefficiencies may be discovered and eliminated, reducing the product’s cost. 3. Traditional cost accounting undercosts complex products and overstates their profit margins. 4. ABC may be used for decision making but not necessarily for inventory valuation.
