The management of Spotted Cow Dairy Company now plans to use the multiple production department factory overhead rate method. The total factory overhead associated with each department is as follows:

Blending Department $342,000
Department 324,000
Total $666,000

Determine the multiple production department factory overhead rates, using machine hours for the Blending Department and direct labor hours for the Packing Department.

total overhead costs for blending department = $342,000

total machine hours blending department = 2,960

overhead rate per machine hour = $342,000 / 2,960 hours = $115.5405405 per machine hour

total overhead costs for packaging department = $324,000

total direct labor hours packaging department = 800

overhead rate per direct labor hour = $324,000 / 800 hours = $405 per machine hour

product             blending department             packaging department

Whole milk       1,210 x $115.54 = $139,804     260 x $405 = $105,300

Skim milk          980 x $115.54 = $113,230       280 x $405 = $113,400

Cream               770 x $115.54 = $88,966       260 x $405 = $105,300

total                       $342,000                                 $324,000
