Q 4 Abdulkarim Company is using job costing system. The allocation base for overhead is number of machine hours. The company uses normal costing to compute the overhead allocation rate.
The following data are available for 2017 year:
Estimated total overhead cost $270,000
Estimated total number of machine-hours 200,000
Actual total overhead cost $290,000
Actual total number of machine-hours 220,000
Job 630 used 14, 000 machine hours.
The company had job 630 and other jobs during the year.
a. Calculate the estimated overhead allocation rate.
b. Compute the overhead allocated to job 630.
c. Calculate total allocated overhead and analyze the value of allocated overhead.
d. Explain the Concept of Job Costing?
a)
Estimated overhead allocation rate = Estimated total overhead cost /Estimated total number of machine-hours
= $270000/200000 = $1.35
b)
The overhead allocated to job 630 (estimated) = $1.35*14000 = 18900
c)
Total allocated overhead (Actual) = Actual total overhead cost/Actual total number of machine-hours *(Machine hours used by Job 360)
= 290000/220000 * 14000 = $18454.55
Actual overhead allocated to job 360 is $18454.55 and estimated overhead allocated to job 360 is 18900. It means that there is under application of overhead as per estimation.
d)
Job Costing is also termed as Terminal Costing or Specific Order Costing. Job costing is a type of costing method in which there are specific orders or contracts and the work consists of separated contracts, batches and jobs.
