O'Reilly Corporation uses direct labor-hours to calculate its annual plantwide predetermined overhead. For the current period's estimated level of production, O'Reilly Corporation estimated that 39,000 direct labor-hours would be required. Estimated fixed manufacturing overhead cost is $599,000 for the current period and variable manufacturing overhead cost of $3.00 per direct labor-hour. O'Reilly Corporation's actual manufacturing overhead cost for the period was $788,379 and its actual total direct labor was 39,500 hours. Required: Compute the company's plantwide predetermined overhead rate for the year. (Round your answer to 2 decimal places.) Answer is complete but not entirely correct. Predetermined overhead $ .

Predetermined manufacturing overhead rate= $18.36 per direct labor hour

Explanation:

Giving the following information:

Estimated overhead cost for the period= $599,000

Variable overhead rate= $3 per DLH

Number of estimated direct labor hours= 39,000

To calculate the predetermined manufacturing overhead rate we need to use the following formula:

Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base

Predetermined manufacturing overhead rate= (599,000 / 39,000) + 3

Predetermined manufacturing overhead rate= $18.36 per direct labor hour

OR:

Fixed overhead rate= 599,000/39,000= $15.36 per DLH

Variable overhead rate= $3 per DLH

Plantwide overhead rate= $18.36 per direct labor hour
