The Oakman Company manufactures products in two departments: Mixing and Packaging. The company allocates manufacturing overhead using a single plantwide rate with direct labor hours as the allocation base. Estimated overhead costs for the year are $810,000, and estimated direct labor hours are 360,000. In October, the company incurred 20,000 direct labor hours.

Requirements

1. Compute the predetermined overhead allocation rate. Round to two decimal places.

Short Answer

Expert verified

Predetermine overhead allocation rate is $2.25.

Step by step solution

01

Predetermine overhead allocation rate

Predetermine overhead allocation rate is the per-unit overhead cost on the basis of the allocation base. It is calculated by dividing the total overhead cost by the estimated quantity of allocation base.
