Traceable amount of the excess in each of the variances:
Direct Materials:
Materials price variance $0.54 U
Materials quantity variance $0.00 $0.54 U
Direct Labor:
Labor rate variance $0.46 F
Labor efficiency variance $0.36 U $0.10 F
Variable Overhead:
Variable overhead rate variance $0.46 F
Variable overhead efficiency variance $0.10 U $0.36 F
Excess of actual cost over standard cost per unit $0.08 U
Traceable amount of the excess apparent to inefficient use of labor time:
Labor efficiency variance $0.36 U
Variable overhead efficiency variance $0.10 U
Total amount attributable to labor inefficiency $0.46 U
Amount attributable to other variances:
Excess of actual over standard cost per unit $0.08 U
Less: Total amount attributable to labor inefficiency $0.46 U
Total amount attributable to other variances $0.38 F
In summary, if only the labor time was efficiently used, the variances
for the month would have resulted in a favorable variance of $0.38
instead of an unfavorable variance of $0.08.
No, even though the $0.08 excess cost is well within the 2%
limit set by the company for acceptable variances when we look
closer into the details, there is a large material price variance
that will require further investigation.
Further, when we traced back the source of the excess, Direct
Material Variance takes the biggest part on it with $0.54
Unfavorable variance per unit.
Also, there is an unfavorable labor inefficiency variance of
$4,320 and an unfavorable variable efficiency variance of
$1,200. These two variances signal that idle time may be
present resulting in an increase in labor hours. Thus, the
company should look into opportunities that will improve their
efficiency.
