(Predetermined OH rates; capacity measures) Albertan Electronics makes inexpensive GPS navigation devices and uses a normal cost system that applies over- head based on machine hours. The following 2010 budgeted data are available: Variable factory overhead at 100,000 machine hours $1,250,000
Variable factory overhead at 150,000 machine hours 1,875,000
Fixed factory overhead at all levels between 10,000 and 180,000 machine hours
1,440,000
Practical capacity is 180,000 machine hours; expected capacity is two-thirds of practical.
a. What is Albertan Electronics’ predetermined variable OH rate?
b. What is the predetermined FOH rate using practical capacity?
c. What is the predetermined FOH rate using expected capacity?
d. During 2010, the firm records 110,000 machine hours and $2,710,000 of overhead costs. How much variable overhead is applied? How much fixed overhead is applied using the rate found in part (b)? How much fixed overhead is applied using the rate found in part (c)? Calculate the total under- or over applied overhead for 2010 using both fixed FOH rates.

Explanation:

a) Available 2010 budgeted data:

Variable factory overhead at 100,000 machine hours $1,250,000 ($12.50)

Variable factory overhead at 150,000 machine hours 1,875,000 ($12.50)

Fixed factory overhead at all levels between 10,000 and 180,000 machine hours  = 1,440,000 ($8.00)

Practical capacity is 180,000 machine hours; expected capacity is two-thirds of practical (120,000) = $12 ($1,440,000/120,000)

Predetermined Overhead Rate:

Variable factory overhead =         $12.50

Fixed factory overhead =                 8.00

Predetermined overhead rate = $20.50

During 2010, the firm records 110,000 machine hours and $2,710,000 of overhead costs. How much variable overhead is applied? How much fixed overhead is applied using the rate found in part (b)? How much fixed overhead is applied using the rate found in part (c)? Calculate the total under- or overapplied overhead for 2010 using both fixed FOH rates.

Variable overhead applied = $12.50 * 110,000 =    $1,375,000

Fixed overhead applied with $8 * 110,000 =               880,000

Total overhead applied                                          $2,255,000

Underapplied overhead = ($2,710,000 -2,255,000) 455,000

Variable overhead applied = $12.50 * 110,000 =    $1,375,000

Fixed overhead applied with $12 * 110,000 =           1,320,000

Total overhead applied                                          $2,695,000

Underapplied overhead = ($2,710,000 -2,695,000)    15,000
