Exercise 11A-2 (continued)
3. Variable overhead rate variance:
Exercise 11A-3 (15 minutes)
1. The total overhead cost at the denominator level of activity must be
determined before the predetermined overhead rate can be computed.
Total fixed overhead cost per year .................................
$250,000
Total variable overhead cost
($2 per DLH × 40,000 DLHs) ......................................
80,000
Total overhead cost at the denominator level of activity ..
$330,000
Overhead at the denominator level of activity
Predetermined =
overhead rate Denominator level of activity
$330,000
= = $8.25 per DLH
40,000 DLHs
2.
Standard direct labor-hours allowed for
the actual output (a) ...........................
38,000
DLHs
Predetermined overhead rate (b) ...........
$8.25
per DLH
Overhead applied (a) × (b) ....................
$313,500
Solutions Manual, Appendix 11A 53
Exercise 11A-4 (10 minutes)
Company A:
This company has a favorable volume variance because the
standard hours allowed for the actual production are greater
than the denominator hours.
Company B:
This company has an unfavorable volume variance because
the standard hours allowed for the actual production are less
than the denominator hours.
Company C:
This company has no volume variance because the standard
hours allowed for the actual production and the denominator
hours are the same.

Total standard cost per unit ..............................................
$80.00
*30,000 DLHs ÷ 10,000 units = 3 DLHs per unit.
