WIP – FOH12,000

During the month the cost of material purchased was $120,000, direct labor cost incurred was $160,000 and factory overhead applicable to production was $60,000, on April 30 inventories were:

$
Raw Material46,000
Finished Goods44,000
WIP – Material10,000
WIP – Labour18,000
WIP – FOH8,000

Problem No. 2: (Charging Actual FOH to Jobs)

The Moon Manufacturing Co. has a partial job order cost system instead of predetermining a factory overhead rate. The company computes a separate factory overhead rate at the end of each month and this rate is used to charge factory overhead to the jobs worked on during that month using the number of direct labour hours used on the jobs as the basis of such allocation. In the following table, the actual factory overhead costs and the direct labour hours for the past two months are listed.

MayJune
Actual Factory Overhead Costs$6,000$12,000
Actual direct labour hours15,00020,000

During this two month period one customer sent in an identical order each month, calling for the production of 1,000 units, requiring 400 direct labour hours at $1.00 per hour and material $750.

Required:

Compute (a) The total and the unit cost for the job in each of the two months and (b) Give your comments regarding this method of charging actual factory overhead costs to jobs.

Solution

(a).

Computing Actual FOH to Jobs

(b). Comments:

It is clear from the above calculation that charging actual FOH Costs to Jobs gives inaccurate and misleading results. The company should use predetermined FOH rates for correct computation and control.
