Jmes Graham Manufacturing is a small manufacturer that uses machine-hours as its
activity base for assigned overhead costs to jobs. The company estimated the
following amounts for 2019 for the company, for Job 62 and Job 63:
Company Job 62 Job 63
Direct materials $60,000 $4,500 $7,100
Direct labor $25,000 $2,500 $4,200
Manufacturing
overhead costs $72,000
Machine hours 90,000 1,350 3,100
During 2019, the actual machine-hours totaled 95,000, and actual overhead costs were $71,000. Job 62 consisting of 1,000 units and Job 63 consisting of 2000 units were completed during the month.
Instructions:
A) Compute the predetermined overhead rate.
B) Compute the total manufacturing costs for Job 62 and Job 63.
C) Compute the unit cost of Jobs 62 and 63.
D) How much overhead is over or underapplied for the year for the company? State amount and whether it is over- or underapplied.
E) If Graham Manufacturing sells Job 62 for $14,000 and $18,000 for Job 63, compute the gross profit.

Instructions are below.

Explanation:

Giving the following information:

Company - Job 62 - Job 63

Direct materials: $60,000 - $4,500 - $7,100

Direct labor: $25,000 - $2,500 - $4,200

overhead costs $72,000

Machine hours: 90,000 - 1,350 - 3,100

During 2019, the actual machine-hours totaled 95,000, and actual overhead costs were $71,000. Job 62 consisting of 1,000 units and Job 63 consisting of 2000 units were completed during the month.

A) To calculate the estimated manufacturing overhead rate we need to use the following formula:

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

Estimated manufacturing overhead rate= 72,000/90,000

Estimated manufacturing overhead rate=  0.8 per machine-hour

B) Total manufacturing cost= direct material + direct labor + allocated overhead

Job 62:

Total manufacturing cost= 4,500 + 2,500 + 0.8*1,350

Total manufacturing cost= $8,080

Job 63:

Total manufacturing cost= 7,100 + 4,200 + 0.8*3,100

Total manufacturing cost= $13,780

C) Unitary cost= total cost/ number of units

Job 62:

Unitary cost= 8,080/1,000= $8.08

Job 63:

Unitary cost= 13,780/2,000= $6.89

D) First, we need to apply overhead for the company as a whole:

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

Allocated MOH= 0.8*95,000

Allocated MOH= $76,000

Now, we can calculate the over/under applied overhead:

Under/over applied overhead= real overhead - allocated overhead

Under/over applied overhead= 71,000 - 76,000

Overapplied overhead= $5,000

E) Job 62= 14,000

Job 63= 18,000

Gross profit= sales - cost of goods sold

Job 62:

Gross profit= 14,000 - 8,080= $5,920

Job 63:

Gross profit= 18,000 - 13,780= $4,220
