(a) Compute all of the variances for (1) direct materials and (2) direct labor.
(b) Compute the total overhead variance.
(a) 1. Total materials variance:
( AQ X AP ) (11100
X $2.10) |
– – |
( SQ X SP ) (10300
X $1.95) |
= |
$3225 U |
Materials price variance:
( AQ X AP ) (11100
X $2.10) |
– – |
( AQ X SP ) (11100
X $1.95) |
= |
$1665 U |
Materials quantity variance:
( AQ X SP ) (11100 X $1.95) |
– – |
( SQ X SP ) (10300
X $1.95) |
= |
$1560 U |
2. Total labor variance:
( AH X AR ) (15000
X $10*) |
– – |
( SH X SR ) (15300
X $9.5**) |
= |
$4650 U |
*$150000 / 15000 = 10 **$145350 ÷ 15300 = 9.5
Labor price variance:
( AH X AR ) (15000
X $10*) |
– – |
( AH X SR ) (15000
X $9.5) |
= |
$7500 U |
Labor quantity variance:
(AH X SR ) (15000
X $9.5) |
– – |
( SH X SR ) (15300
X $9.5) |
= |
$2850 F |
(b) Total overhead variance:
Actual Overhead $232308 |
– – |
Overhead |
= |
$2700 F |
*Overhead is applied on the basis of standard machine hours. 3.20 hours of machine time are required for each direct labor hour.
*15300 X 3.20 = 48960 machine hours
**Overhead rate
Variable overhead rate per machine hour |
$3.20 |
Fixed overhead rate per machine hour |
$1.60 |
Overhead rate |
