Question

Ma Barker Company has a job-order costing system and uses a predetermined overhead rate based on direct labor-hours to apply manufacturing overhead to jobs. Manufacturing overhead cost and direct labor hours were estimated at $100,000 and 40,000 hours, respectively, for the year. In July, Job #334 was completed at a cost of $5,000 in direct materials and $2,400 in direct labor. The labor rate is $6 per hour. If Job #334 contained 200 units, the unit product cost on the completed job cost sheet would be:

Answer 1

Job 334 total cost: $ 8,400

Unit cost: 8,400 / 200 = $ 42

Step-by-step explanation:

Total cost: Material + Labor + Overhead

Material: 5,000

Labor: 2,400

Overhead:

`(Cost\: Of \:Manufacturing \:Overhead)/(Cost \:Driver)= Overhead \:Rate`

We distribute the expected cost over the expected base:

expected cost: 100,000

cost driver: 40,000 labor hours

cost per hour: 100,000 / 40,000 = 2.5 predetermined overhead

Now we multiply this rate by the hours of the job to know Applied Overhead:

job labor hours x overhead rate:

Job #334 had 2,400 labor cost / $6 rate per hour = 400 hours

400 x 2.5 = 1,000

Total cost: 5,000 + 2,400 + 1,000 = 8,400
