Snappy 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 $54,400 and 32,000 hours, respectively, for the year. In July, Job #334 was completed at a cost of $2,736 in direct materials and $1,664 in direct labor. The labor rate is $5.20 per hour. By the end of the year, Snappy had worked a total of 37,000 direct labor-hours and had incurred $64,650 actual manufacturing overhead cost. If Job #334 contained 120 units, the unit product cost on the completed job cost sheet would be:

Unitary cost= $41.2

Explanation:

First, we need to calculate the predetermined overhead rate:

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= (54,400/32,000)

Predetermined manufacturing overhead rate= $1.7 per direct labor hour

Now, we can allocate overhead based on actual direct labor hours:

Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base

Direct labor hours= 1,664 / 5.2= 320

Allocated MOH= 1.7*320= $544

Finally, the total cost and unitary cost:

Total cost= 544 + 1,664 + 2,736

Total cost= $4,944

Unitary cost= 4,944 / 120

Unitary cost= $41.2
