Southern Rim Parts estimates its manufacturing overhead to be $418,500 and its direct labor costs to be $930,000 for year 1. The first three jobs that Southern Rim worked on had actual direct labor costs of $52,000 for Job 301, $77,000 for Job 302, and $110,000 for Job 303. For the year, actual manufacturing overhead was $464,000 and total direct labor cost was $847,000. Manufacturing overhead is applied to jobs on the basis of direct labor costs using pre-determined rates. Required:
A. How much overhead was assigned to each of the three jobs, 301, 302, and 303?
B. What was the over- or underapplied manufacturing overhead for year 1?

Results are below.

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= 418,500/930,000

Predetermined manufacturing overhead rate= $0.45 per direct labor dollar

Now, we can allocate overhead yo Job 301, 302, 303:

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

Job 301= 0.45*52,000= $23,400

Job 302= 0.45*77,000= $34,650

Job 303= 0.45*110,00= $49,500

Finally, we allocate overhead for the whole company and calculate the under/over allocation:

Allocated MOH= 0.45*847,000= $381,150

Under/over applied overhead= real overhead - allocated overhead

Under/over applied overhead= 464,000 - 381,150

Under/over applied overhead= $82,850 underallocated

answer; the correct answer should be (demonstrations); good luck
