80. Fixed Overhead Variances
• Total fixed overhead variance
– Difference between actual fixed overhead
costs and the standard fixed overhead
costs that are applied to good units
produced using the standard fixed
overhead rate

82. Fixed Overhead Variances (cont’d)
At Cambria Company, each leather bag requires 2.4 standard direct
labor hours and the standard fixed overhead rate is $3.25 per direct
labor hour. During August, the company incurred $1,600 of actual
fixed overhead costs
Overhead applied to good units produced
Standard fixed rate × standard direct labor hours allowed =
$3.25 per hour × (180 bags × 2.4 hours per bag) =
$3.25 per hour × 432 hours = $1,404
Less actual cost

83. Fixed Overhead Variances (cont’d)
• Total fixed overhead cost variance must
be broken into two parts to find the
cause of the variance
– Fixed overhead budget variance
– Fixed overhead volume variance

84. Fixed Overhead Variances (cont’d)
• Fixed overhead budget variance
– Difference between the budgeted and
actual fixed overhead costs
– Also called budgeted fixed overhead
variance
Fixed OH Budget Variance = Budgeted Fixed Overhead −
Actual Fixed Overhead
= $1,300 − $1,600
= $300 (U)

85. Fixed Overhead Variances (cont’d)
• Fixed overhead volume variance
– Difference between budgeted fixed
overhead costs and manufacturing
overhead costs applied to production using
the standard fixed overhead rate
Standard fixed OH applied for 432 direct labor hours
$3.25 per direct labor hour × (180 bags × 2.4 hours per bag)
Less total budgeted fixed overhead

86. Fixed Overhead Variances (cont’d)
• A volume variance will occur if more or less
than normal capacity is used
– Fixed overhead volume variance measures the
use of existing facilities and capacity
– Favorable overhead volume variance
• Capacity exceeds the expected amount
– Unfavorable overhead volume variance
• Company operates at a level below normal capacity
– May be in best interest of company during periods of slow
sales
– Means company is not building up excess inventory

90. Using Cost Variances to Evaluate Managers’
Performance
• Objective 7
– Explain how variances are used to
evaluate managers’ performance

22–90
91. Using Cost Variances to Evaluate Managers’
Performance
• The effectiveness and fairness of a
manager's performance evaluation
depends on
– Human factors
– Company policies
• Should be based on input from managers and
employees
• Should specify procedures that managers are
to use
Copyright © Houghton Mifflin Company. All rights reserved.
22–91
92. Using Cost Variances to Evaluate Managers’
Performance (cont’d)
• Procedures that should be specified for
managers
– Preparing operational plans
– Assigning responsibility for carrying out the
operational plans
– Communicating operational plans to key personnel
– Evaluating performance in each area of
responsibility
– Identifying causes of significant variances from the
operational plan
– Taking corrective action to eliminate problems

93. Using Cost Variances to Evaluate Managers’
Performance (cont’d)
• Variance analysis
– Provides detailed data about differences
between standard and actual costs
• Effective at pinpointing efficient and inefficient
operating areas
– Basic comparison of budgeted and actual data not
as effective
Copyright © Houghton Mifflin Company. All rights reserved.
22–93
94. Using Cost Variances to Evaluate Managers’
Performance (cont’d)
• Effective managerial performance reports
based on standard costs and related
variances should
– Identify
• Causes of the differences
• Personnel involved
• Corrective actions taken
– Be tailored to the manager’s specific areas of
responsibility
• Explain clearly and accurately in what way the manager’s
department did or did not meet operating expectations
Managers should only be held accountable for cost areas under their control

22–94
95. Using Cost Variances to Evaluate Managers’
Performance (cont’d)
• Managerial performance reports should
– Summarize all cost data
– Include variances for direct materials,
direct labor, and manufacturing overhead
– Identify
• Causes of variances
• Corrective actions taken
Copyright © Houghton Mifflin Company. All rights reserved.
22–95
96. Using Cost Variances to Evaluate Managers’
Performance (cont’d)
• The occurrence of a variance does not
indicate poor performance
• If a variance consistently occurs, its
cause is not identified, and no
corrective action is taken, it may
indicate poor performance on the part
of the manager

97. Discussion
Q. What items should be included in an
effective managerial performance
report?
A. Summarization of all cost data
Variances for direct materials, direct
labor, and manufacturing overhead
Identification of the causes of the
variances, personnel involved, and any
corrective actions taken
Copyright © Houghton Mifflin Company. All rights reserved.
22–97
98. Time for Review
1. Define standard costs and describe
how managers use standard costs in
the management cycle
2. Explain how standard costs are
developed and compute a standard
unit cost
3. Prepare a flexible budget and describe
how variance analysis is used to
control costs

99. And Finally…
4. Compute and analyze direct materials
variances
5. Compute and analyze direct labor
variances
6. Compute and analyze manufacturing
overhead variances
7. Explain how variances are used to
evaluate managers’ performance
