Blast it!” said David Wilson, president of Teledex Company. “We’ve just lost the bid on the Koopers job by $3,000. It seems we’re either too high to get the job or too low to make any money on half the jobs we bid.”
Teledex Company manufactures products to customers’ specifications and uses a job-order costing system. The company uses a plantwide predetermined overhead rate based on direct labor cost to apply its manufacturing overhead (assumed to be all fixed) to jobs. The following estimates were made at the beginning of the year:
Department | ||||||||
Fabricating | Machining | Assembly | Total Plant | |||||
Manufacturing overhead | $ | 381,500 | $ | 436,000 | $ | 98,100 | $ | 915,600 |
Direct labor | $ | 218,000 | $ | 109,000 | $ | 327,000 | $ | 654,000 |
Jobs require varying amounts of work in the three departments. The Koopers job, for example, would have required manufacturing costs in the three departments as follows:
Department | ||||||||||||
Fabricating | Machining | Assembly | Total Plant | |||||||||
Direct materials | $ | 4,800 | $ | 500 | $ | 3,200 | $ | 8,500 | ||||
Direct labor | $ | 6,400 | $ | 800 | $ | 8,000 | $ | 15,200 | ||||
Manufacturing overhead | ? | ? | ? | ? | ||||||||
Required:
1. Using the company's plantwide approach:
a. Compute the plantwide predetermined rate for the current year.
PREDETERMINED OVERHEAD RATE____________% OF DIRECT LABOR COST
b. Determine the amount of manufacturing overhead cost that would have been applied to the Koopers job.
MANUFACTURING OVERHEAD COST APPLIED______________
2. Suppose that instead of using a plantwide predetermined overhead rate, the company had used departmental predetermined overhead rates based on direct labor cost. Under these conditions:
a.Compute the predetermined overhead rate for each department for the current year.
FABRICATING DEPARTMENT_____% OF DIRECT LABOR COST
MACHINING DEPARTMENT _____% OF DIRECT LABOR COST
ASSEMBLY DEPARTMENT ____% OF DIRECT LABOR COST
b. Determine the amount of manufacturing overhead cost that would have been applied to the Koopers job.
MANUFACTURING OVERHEAD COST APPLIED ______
4. Assume that it is customary in the industry to bid jobs at 150% of total manufacturing cost (direct materials, direct labor, and applied overhead).
a.What was the company’s bid price on the Koopers job using a plantwide predetermined overhead rate?
COMPANY'S BID PRICE __________
b.What would the bid price have been if departmental predetermined overhead rates had been used to apply overhead cost?
