and
Variance Analysis
Slide 11-2
Standard Costs and Budgets
 Standard cost
 Cost that management believes should
be incurred to produce a product or
service under anticipated conditions
 Standard costs can be used by
manufacturing and service companies
 A tool manufacturer may set a standard
cost for producing a hammer
 A bank may set a standard cost for
processing a check
Slide 11-3
Learning objective 1: Explain how standard
costs are developed
Standard Costs and Budgets
 The term standard cost often refers to
the cost of a single unit
 The term budgeted cost often refers to
the cost, at standard, of the total
number of budgeted units
 The cost information contained in
budgets must be consistent with
standard costs
Slide 11-4
Learning objective 1: Explain how standard
costs are developed
Standard Costs and Budgets
 If materials budget indicates purchases of 5,000
pounds, standard cost is $25,000 (5,000 pounds
* $5 standard cost per pound)
 If labor budget is prepared for 1,000 units
produced, 3,000 labor hours are needed at a
standard cost of $30,000 (3,000 hours * $10)

Development of Standard Costs
 Standard costs for material, labor and
overhead are developed in a variety of
ways
 Standard quantity and price for
material may be specified:
 In engineering plans that provide a list
of material
 In recipes or formulas
 By time and motion studies
 In price lists provided by suppliers
Slide 11-7
Learning objective 1: Explain how standard
costs are developed
Development of Standard Costs
 Standard quantity and rate for direct
labor may be specified:
 By time and motion studies
 Through analysis of past data
 By management expectations of rates to
be paid
 In contracts that set labor rates
 Standard costs for overhead involves
procedures similar to those used to
develop predetermined overhead rates
Slide 11-8
Learning objective 1: Explain how standard
costs are developed
Ideal versus Attainable Standards
 In developing standard costs, some
managers emphasize ideal standards
while others use attainable standards
 Ideal standards assumes that no
obstacles to the production process will
be encountered
 Managers who support ideal standards
believe they motivate employees to
strive for the best possible control over
production costs
Slide 11-9
Learning objective 1: Explain how standard
costs are developed
Ideal versus Attainable Standards
 Attainable standards are standard
costs that take into account the
possibility that a variety of
circumstances may lead to costs that
are greater than ideal
 If equipment breakdowns and defects
are a fact of life, it makes sense to plan
for their associated costs
 Most managers support the use of
attainable standards

A General Approach to Variance
Analysis
 Companies that use standard costing
can analyze the difference between a
standard and an actual cost
 Called a standard cost variance
 Determines whether operations are
being performed efficiently
 The analysis is called variance analysis
 It generally involves breaking down the
differences between standard and
actual cost into two components

Interpreting Overhead Volume
Variance
 Volume variances do not signal that
overhead costs are in or out of control
 A volume variance signals that the
quantity of production was greater or
less than anticipated
 The usefulness of the volume variance
is limited
 It signals only that more or fewer units
have been produced than planned when
the standard overhead rate was set

Investigation of Standard Cost
Variances
 Standard cost variances do not provide
definitive evidence that costs are out of
control and managers are not
performing effectively
 They should be viewed as an indicator
of potential problem areas
 The only way to determine whether
costs are being effectively controlled is
to investigate the facts behind the
variances

Management by Exception
 Investigation of standard cost
variances is a costly activity
 A management by exception approach
is to investigate only those variances
that are considered exceptional
 Must determine criteria to measure
what is considered exceptional
 Absolute dollar value of the variance
 The variance as a percent of actual or
standard cost
Slide 11-33
Learning objective 6: Discuss how the management-by-exception approach is
applied to the investigation of standard cost variances
“Favorable” Variances May Be
Unfavorable
 The fact that a variance is favorable
does not mean that is should not be
investigated
 A favorable variance may be indicative
of poor management decisions
 A poor decision regarding the quality
of raw materials might result in an
unfavorable variance in material
quantity
Slide 11-34
Learning objective 7: Explain why a favorable variance may be unfavorable, how process
improvements may lead to unfavorable variances, and why evaluation in terms of variances may
lead to overproduction
Can Process Improvements Lead
to “Unfavorable” Variances?
 A firm may have an unfavorable
variance because it engaged in process
improvements
 They can lead to greater efficiency
which results in actual labor hours
being less than standard labor hours
 Firms should stimulate greater demand
to take advantage of the greater
production capabilities
Slide 11-35
Learning objective 7: Explain why a favorable variance may be unfavorable,
how process improvements may lead to unfavorable variances, and why
evaluation in terms of variances may lead to overproduction
Evaluation in Terms of Variances
Can Lead to Excess Production
 When bottlenecks exist, the department
in front of the bottleneck should not
produce more than the bottlenecked
department can handle
 If it does it will create excess work-inprocess inventory and result in a
negative impact on shareholder value
Slide 11-36
Learning objective 7: Explain why a favorable variance may be unfavorable,
how process improvements may lead to unfavorable variances, and why
evaluation in terms of variances may lead to overproduction
Responsibility Accounting and
Variances
 The central idea of responsibility
accounting is that managers should be
held responsible for only the costs they
can control
 Additionally, managers and workers
should only be held responsible for
variances they can control
