Flexible Budgets and Overhead Analysis

Chapter Eleven


Static Budgets and Performance Reports

Static budgetsare prepared fora single, plannedlevel of activity.

Performance evaluation is difficult when actual activity

differs from the planned level of

activity.

Hmm! Comparingstatic budgets withactual costs is likecomparing apples

and oranges.


Flexible Budgets

Improve performance evaluation.

May be prepared for any activity level in the relevant range.

Show costs that should have beenincurred at the actual level ofactivity, enabling “apples to apples”cost comparisons.

Reveal variances related tocost control.

Let’s look at CheeseCo.


CheeseCo



U = Unfavorable variance CheeseCo was unable to achieve

the budgeted level of activity.

CheeseCo



CheeseCo

F = Favorable variance that occurs when actual costs are less than budgeted costs.



Since cost variances are favorable, havewe done a good job controlling costs?

CheeseCo



I don’t think Ican answer thequestion usinga static budget.

Actual activity is belowbudgeted activity.

So, shouldn’t variable costsbe lower if actual activity

is lower?



The relevant question is . . .“How much of the favorable cost variance is due to lower activity, and how much is due to good cost control?”

To answer the question,we mustthe budget to theactual level of activity.



Preparing a Flexible Budget

To a budget we need to know that: Total variable costs change

in direct proportion to changes in activity.

Total fixed costs remainunchanged within therelevant range. Fixed

Let’s prepare budgets for CheeseCo.

Fixed costs areexpressed as atotal amount.

Variable costs are expressed as a constant amount per hour.

$40,000 ÷ 10,000 hours is$4.00 per hour.

Remember the question: “How much of the total variance is due to lower activity and how much isdue to cost control?”



Static Budgets and Performance How much of the $11,650 favorable variance is due to lower activity and how much is due to cost control?


Difference between original static budgetand actual overhead = $11,650 F.

The Measure of Activity– A Critical Choice

Three importantfactors in selecting an

activity base for an overheadflexible budget

Activity base andvariable overhead

should becausally related.

Activity base shouldnot be expressed

in dollars orother currency.

Activity base shouldbe simple and

easily understood.


Variable Overhead Variances –A Closer Look

If flexible budgetis based onactual hours

If flexible budgetis based on

standard hours

Only a spendingvariance can be

computed.

Both spendingand efficiency

variances can be computed.


ColaCo’s actual production for the period required 3,200 standard machine hours. Actual variable overhead incurred for the period was $6,740. Actual machine hours worked were 3,300. The

standard variable overhead cost per machine hour is $2.00.

Compute the variable overhead spending variance

first using actual hours. Then use standard hours allowed to calculate the variable overhead

efficiency variance.

Activity-based Costingand the Flexible Budget

It is unlikely that allvariable overhead will bedriven by a single activity.

Activity-based costingcan be used when multiple

activity bases drivevariable overhead costs.


Overhead Rates and Overhead Analysis

Overhead from theflexible budget for the

denominator level of activityPOHR =

Recall that overhead costs are assigned to products and services using a predetermined

overhead rate (POHR):

Assigned Overhead = POHR × Standard Activity

Denominator level of activity


The predetermined overhead ratecan be broken down into fixed

and variable components.

The variablecomponent is useful

for preparing and analyzingvariable overhead

variances.

The fixedcomponent is useful

for preparing and analyzingfixed overhead

variances.

Overhead Rates and Overhead Analysis


Normal versus Standard Cost Systems

In a normal costsystem, overhead isapplied to work inprocess based onthe actual numberof hours worked

in the period.

In a standard costsystem, overhead isapplied to work inprocess based onthe standard hours

allowed for the outputof the period.

ColaCo applies overhead basedon machine-hour activity.

Let’s calculate overhead rates.


Rate = Total Variable Overhead ÷ Machine Hours

This rate is constant at all levels of activity.

Rate = Total Fixed Overhead ÷ Machine Hours

This rate decreases when activity increases.

The total POHR is the sum ofthe fixed and variable ratesfor a given activity level.




ColaCo’s actual production required 3,200 standard machine hours. Actual fixed overhead was $8,450. The predetermined overhead rate is

based on 3,000 machine hours.
