Duration-Based Costing

Gee Manufacturing produces two models of camshafts used in the production of automobile engines: Regular and High Performance. Gee currently uses an ABC system to assign costs to the two products. For the coming year, the company has the following overhead activities, costs, and activity drivers:

Activity	Expected Cost		Activity Driver	Activity Capacity
Setups	$214,612		Setup hours	10,000
Machining	$420,000		Machine hours	20,000
Moving	$112,500		Move hours	5,000
Total OH	$747,112

At practical capacity, the expected activity demands for each product are as follows:

	Regular Performance Model		High Performance Model
Units completed	30,000		8,000
Setup hours	8,000		2,000
Machine hours	6,000		14,000
Moving hours	1,000		4,000

The production cycle time for the regular performance camshaft is 0.50 (hours per unit) and that of the high performance camshaft is 2.5 (hours per unit).

1. Calculate the consumption ratios for each activity. Use these consumption ratios to assign the total overhead to each camshaft model and then calculate the overhead cost per unit for each model (round unit cost to two decimal places).

Unit overhead cost:

2. Calculate the total and per unit overhead assigned to each model using DBC (assume you only know cycle time, total overhead costs, and units at practical capacity). Round the overhead rate to four decimal places.
