Poehling Medical Center expects to use the operating room an average of eight hours per day, seven days per week. In addition, the operating room will be shut down two weeks per year for general repairs. a. Calculate the estimated number of operating room hours for the year. hours b.

The actual overhead costs incurred for January were $80,000. Determine the overapplied operating overhead or underapplied operating overhead for the period. Enter your answer as a positive number. $

Answer 1

a)

Estimated number of operating room hours for the year = Number of operating hours in a day x Operating days in week x Number of operating weeks

= 8 x 7 x 50

= 2,800

b)

Predetermined overhead rate = Estimated overheads/Estimated operating room hours

= 1,232,000/2,800

= $440 per operating room hour

c)

Overhead applied = Actual operating room hours used x  Predetermined overhead rate

= 7 x 440

= $3,080

d)

Overhead applied in January = Actual operating room hours used x  Predetermined overhead rate

= 186 x 440

= $81,840

Actual overheads = $80,000

Over applied overhead = Overhead applied - Actual overhead

= 81,840 - 80,000

= $1,840
