Departmental Overhead Rates

The overhead rate for the Grinding Department is computed as follows (assuming the normal level of activity is 71,000 MH):

OH rate = $355,000 71,000 = $5 per MH

The overhead rate for the assembly department is computed as follows (assuming the normal level of activity is 107,500 DLH):

OH rate = $215,000 107,500 = $2 per DLH
