Predetermined overhead rate is a rate used to charge overhead cost to jobs in production; the rate is established in advance for each period by use of estimates of total manufacturing overhead cost and of the total allocation base for the period.redetermined overhead rate is a rate used to charge overhead cost to jobs in production; the rate is established in advance for each period by use of estimates of total manufacturing overhead cost and of the total allocation base for the period.
These estimates are based on the previous yearâs overhead costs and direct labor hours and are adjusted for expected increases in demand the coming year. The predetermined overhead rate is $32 per direct labor hour (= $8,000,000 Ã· 250,000 direct labor hours).Thus, as shown in Figure 3.1 Using One Plantwide Rate to Allocate SailRite Companyâs Overhead , products are charged $32 in overhead costs for each direct labor hour worked.nswer: The choice of an allocation method depends on how managers decide to group overhead costs and the desired accuracy of product cost information. Groups of overhead costs are called cost poolsA collection of overhead costs, typically organized by department or activity. .
