2. Job Order Costing – Application of Overhead using a pre-determined OH rate (4pts): Skaro, Ltd. is a manufacturer that uses a job-order costing system. Assume Skaro uses a single plantwide predetermined Factory OH rate to apply overhead, and bases their predetermined OH rate on machine hours (Mh). At the beginning of 2020, the firm made the following estimates for the upcoming year:
Estimated Direct labor hours (DLh) |
5,100 DLh |
Estimated Machine hours (Mh) |
22,000 Mh |
Estimated total Variable Factory OH cost |
$295,600 |
Estimated total Fixed Factory OH cost |
$126,800 |
PART A (1pt): Calculate the predetermined OH rate. Round your final answer to 2 decimal places.
PART B (3pts): During January 2020, Skaro started and completed 2 jobs: PC12 and JW13. Each job had the following information, according to their job cost sheets:
Job PC12: |
Job JW13: |
|||

DM costs |
$1,305 |
DM costs |
$982 |
|
DL costs |
$135 |
DL costs |
$105 |
Calculate the total manufacturing cost assigned to each job.
Answer: | ||
A) | ||
Predetermined OH rate = Estimated total Factory OH cost / Estimated Machine hours = ( $ 295,600 + $ 126,800 ) / 22,000 Mh = $ 422,400 / 22,000 |
$ 19.20 per Mh | |
B) | ||
Particulars | Job PC12 | Job JW13 |
DM costs | $ 1,305 | $ 982 |
DL costs | $ 135 | $ 105 |
Applied OH Costs |
$ 672 ( 35 Mh x $ 19.20) |
$ 556.80 (29 Mh x $ 19.20 ) |
Total manufacturing cost assigned | $ 2,112 | $ 1,643.80 |
