CHAPTER 8
FLEXIBLE BUDGETS, OVERHEAD COST VARIANCES, AND
MANAGEMENT CONTROL
8-1 Effective planning of variable overhead costs involves:
1. Planning to undertake only those variable overhead activities that add value for
customers using the product or service, and
2. Planning to use the drivers of costs in those activities in the most efficient way.
8-2 At the start of an accounting period, a larger percentage of fixed overhead costs are locked-
in than is the case with variable overhead costs. When planning fixed overhead costs, a company
must choose the appropriate level of capacity or investment that will benefit the company over a
long time. This is a strategic decision.
8-3 The key differences are how direct costs are traced to a cost object and how indirect costs
are allocated to a cost object:
Actual Costing
Standard Costing
Direct costs
Actual prices
× Actual inputs used
Standard prices
× Standard inputs allowed for actual output
Indirect costs
Actual indirect rate
× Actual inputs used
Standard indirect cost-allocation rate
× Standard quantity of cost-allocation base
allowed for actual output
8-4 Steps in developing a budgeted variable-overhead cost rate are
1. Choose the period to be used for the budget.
2. Select the cost-allocation bases to use in allocating variable overhead costs to the
output produced.
3. Identify the variable overhead costs associated with each cost-allocation base.
4. Compute the rate per unit of each cost-allocation base used to allocate variable
overhead costs to output produced.
8-5 Two factors affect the spending variance for variable manufacturing overhead:
a. price changes of individual inputs (such as energy and indirect materials) included in
variable overhead relative to budgeted prices
b. percentage change in the actual quantity used of individual items included in variable
overhead cost pool, relative to the percentage change in the quantity of the cost driver
of the variable overhead cost pool
8-6 Possible reasons for a favorable variable-overhead efficiency variance include:
Workers are more skillful in using machines than budgeted.
Production scheduler was able to schedule jobs better than budgeted, resulting in
lower-than-budgeted machine-hours.
Machines operated with fewer slowdowns than budgeted.
Machine time standards were overly lenient.
page-pf2
8-7 A direct materials efficiency variance indicates whether more or less direct materials were
used than was budgeted for the actual output achieved. A variable manufacturing overhead
efficiency variance indicates whether more or less of the chosen allocation base was used than was
budgeted for the actual output achieved.
8-8 Steps in developing a budgeted fixed-overhead rate are
1. Choose the period to use for the budget.
2. Select the cost-allocation base to use in allocating fixed overhead costs to output
produced.
3. Identify the fixed-overhead costs associated with each cost-allocation base.
4. Compute the rate per unit of each cost-allocation base used to allocate fixed overhead
costs to output produced.
8-9 The relationship for fixed-manufacturing overhead variances is:
There is never an efficiency variance for fixed overhead because managers cannot be more
or less efficient in dealing with an amount that is fixed regardless of the output level. The result is
that the flexible-budget variance amount is the same as the spending variance for fixed-
manufacturing overhead.
8-10 For planning and control purposes, fixed overhead costs are a lump sum amount that is not
controlled on a per-unit basis. In contrast, for inventory costing purposes, fixed overhead costs are
allocated to products on a per-unit basis.
8-11 An important caveat is what change in selling price might have been necessary to attain
the level of sales assumed in the denominator of the fixed manufacturing overhead rate. For
example, the entry of a new low-price competitor may have reduced demand below the
denominator level if the budgeted selling price was maintained. An unfavorable production-
volume variance may be small relative to the selling-price variance had prices been dropped to
attain the denominator level of unit sales.
8-12 A strong case can be made for writing off an unfavorable production-volume variance to
cost of goods sold. The alternative is prorating it among inventories and cost of goods sold, but
this would “penalize” the units produced (and in inventory) for the cost of unused capacity, i.e.,
for the units not produced. But, if we take the view that the denominator level is a “soft” number
i.e., it is only an estimate, and it is never expected to be reached exactlythen it makes more sense
to prorate the production volume variancewhether favorable or notamong the inventory stock
and cost of goods sold. Prorating a favorable variance is also more conservative: It results in a
Flexible-budget variance
Spending variance
page-pf3
8-
3
lower operating income than if the favorable variance had all been written off to cost of goods
sold. Finally, prorating also dampens the efficacy of any steps taken by company management to
manage operating income through manipulation of the production volume variance. In sum, a
production-volume variance need not always be written off to cost of goods sold.
8-13 The four variances are
Variable manufacturing overhead costs
spending variance
efficiency variance
Fixed manufacturing overhead costs
spending variance
production-volume variance
8-14 Interdependencies among the variances could arise for the spending and efficiency
variances. For example, if the chosen allocation base for the variable overhead efficiency variance
is only one of several cost drivers, the variable overhead spending variance will include the effect
of the other cost drivers. As a second example, interdependencies can be induced when there are
misclassifications of costs as fixed when they are variable and vice versa.
8-15 Flexible-budget variance analysis can be used in the control of costs in an activity area by
isolating spending and efficiency variances at different levels in the cost hierarchy. For example,
an analysis of batch costs can show the price and efficiency variances from being able to use longer
production runs in each batch relative to the batch size assumed in the flexible budget.
8-16 (20 min.) Variable manufacturing overhead, variance analysis.
Esquire Clothing is a manufacturer of designer suits. The cost of each suit is the sum of three
variable costs (direct material costs, direct manufacturing labor costs, and manufacturing overhead
costs) and one fixed-cost category (manufacturing overhead costs). Variable manufacturing
overhead cost is allocated to each suit on the basis of budgeted direct manufacturing labor-hours
per suit. For June 2014, each suit is budgeted to take 4 labor-hours. Budgeted variable
manufacturing overhead cost per labor-hour is $12. The budgeted number of suits to be
manufactured in June 2014 is 1,040.
Actual variable manufacturing costs in June 2014 were $52,164 for 1,080 suits started and
completed. There were no beginning or ending inventories of suits. Actual direct manufacturing
labor-hours for June were 4,536.
Required:
1. Compute the flexible-budget variance, the spending variance, and the efficiency variance for
variable manufacturing overhead.
2. Comment on the results.

2. Esquire had a favorable spending variance of $2,268 because the actual variable overhead
rate was $11.50 per direct manufacturing labor-hour versus $12 budgeted. It had an unfavorable
efficiency variance of $2,592 U because each suit averaged 4.2 labor-hours (4,536 hours ÷ 1,080
suits) versus 4.0 budgeted labor-hours.
8-17 (20 min.) Fixed-manufacturing overhead, variance analysis (continuation of 8-16).
Esquire Clothing allocates fixed manufacturing overhead to each suit using budgeted direct
manufacturing labor-hours per suit. Data pertaining to fixed manufacturing overhead costs for June
2014 are budgeted, $62,400, and actual, $63,916.
Required:
1. Compute the spending variance for fixed manufacturing overhead. Comment on the results.

The fixed manufacturing overhead spending variance and the fixed manufacturing flexible
budget variance are the same––$1,516 U. Esquire spent $1,516 more than the $62,400 budgeted
amount for June 2014.
The production-volume variance is $2,400 F. This arises because Esquire utilized its
capacity more intensively than budgeted (the actual production of 1,080 suits exceeds the budgeted
1,040 suits). This results in overallocated fixed manufacturing overhead of $2,400 (4 × 40 × $15).
Esquire would want to understand the reasons for a favorable production-volume variance. Is the
market growing? Is Esquire gaining market share? Will Esquire need to add capacity?
8-18 (30 min.) Variable manufacturing overhead variance analysis.
The French Bread Company bakes baguettes for distribution to upscale grocery stores. The
company has two direct-cost categories: direct materials and direct manufacturing labor. Variable
manufacturing overhead is allocated to products on the basis of standard direct manufacturing
labor-hours. Following is some budget data for the French Bread Company:

3. Spending variance of $176,400 U. It is unfavorable because variable manufacturing
overhead was 35 percent higher than planned. A possible explanation could be an increase in
energy rates relative to the rate per standard labor-hour assumed in the flexible budget.
Efficiency variance of $56,000 F. It is favorable because the actual number of direct
manufacturing labor-hours required was lower than the number of hours in the flexible budget.

Labor was more efficient in producing the baguettes than management had anticipated in the
budget. This could occur because of improved morale in the company, which could result from an
increase in wages or an improvement in the compensation scheme.
Flexible-budget variance of $120,400 U. It is unfavorable because the favorable efficiency
variance was not large enough to compensate for the large unfavorable spending variance.
8-19 (30 min.) Fixed manufacturing overhead variance analysis (continuation of 8-18).
The French Bread Company also allocates fixed manufacturing overhead to products on the basis
of standard direct manufacturing labor-hours. For 2014, fixed manufacturing overhead was
budgeted at $4.00 per direct manufacturing labor-hour. Actual fixed manufacturing overhead
incurred during the year was $272,000.
Required:
1. Prepare a variance analysis of fixed manufacturing overhead cost. Use Exhibit 8-4 (page 304)
as a guide.
2. Is fixed overhead underallocated or overallocated? By what amount?
3. Comment on your results. Discuss the variances and explain what may be driving them.
SOLUTION
1. Budgeted standard direct manufacturing labor used = 0.02 per baguette
Budgeted output = 3,200,000 baguettes
Budgeted standard direct manufacturing labor-hours
= 3,200,000 × 0.02
= 64,000 hours
Budgeted fixed manufacturing overhead costs
= 64,000 × $4.00 per hour
= $256,000
Actual output = 2,800,000 baguettes
Allocated fixed manufacturing overhead
= 2,800,000 × 0.02 × $4

2. The fixed manufacturing overhead is underallocated by $48,000.
3. The production-volume variance of $32,000 U captures the difference between the budgeted
3,200,0000 baguettes and the lower actual 2,800,000 baguettes producedthe fixed cost
capacity not used. The spending variance of $16,000 U means that the actual aggregate of
fixed costs ($272,000) exceeds the budget amount ($256,000). For example, monthly leasing
rates for baguette-making machines may have increased above those in the budget for 2014.
