Static Budgets and Performance Reports

Hmm! Comparingstatic budgets withactual costs is likecomparing apples

and oranges. Static budgets are prepared for a single,

planned level of activity.

Performance evaluation is difficult when actual activity

differs from the planned level of

activity.Let’s look at CheeseCo.

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 which

is unfavorable. So, shouldn’t variable costs

be lower if actual activityis lower?


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

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



Flexible Budgets

Improve performance evaluation.

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

Show revenues and expensesthat should have occurred at theactual level of activity.

Reveal variances due to good costcontrol or lack of cost control.


Flexible Budgets

Central Concept

If you can tell me what your activity wasfor the period, I will tell you what your costs

and revenue should have been.


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 activityand how much is due tocost control?”




Machine hours 10,000 8,000 2,000 U




Static Budgets and Performance How much of the $11,650 is due to activity

and how much is due to cost control?



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

What causesthe cost

There are two primaryreasons for unfavorablevariable overhead variances:1. Spending too much for resources.2. Using the resources inefficiently.


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


Overhead Rates and Overhead Analysis – Example

Let’s look at overhead rates in a budget for ColaCo.


ColaCo prepared this budget for overhead:


Total Variable Total FixedMachine Variable Overhead Fixed Overhead

Hours Overhead Rate Overhead Rate2,000 4,000$ ? 9,000$ ?4,000 8,000 ? 9,000 ?

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.


Hours Overhead Rate Overhead Rate2,000 4,000$ 2.00$ 9,000$ ?4,000 8,000 2.00 9,000 ?



Hours Overhead Rate Overhead Rate2,000 4,000$ 2.00$ 9,000$ 4.50$ 4,000 8,000 2.00 9,000 2.25


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.



Overhead Variances

Let’s use the overhead rates, to determine variable and fixed overhead

variances.


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.

Compute the variable overhead spending and efficiency variances.

Overhead Variances

Now let’s turn our attention

to fixed overhead.




What is ColaCo’s fixed overhead rate for an estimated activity of 3,000 machine hours?






What is ColaCo’s fixed overhead rate for an estimated activity of 3,000 machine hours? Fixed Overhead Rate

FR = $9,000 ÷ 3,000 machine hours FR = $3.00 per machine hour




ColaCo’s actual production required 3,200 standard machine hours. Actual fixed overhead

was $8,450.

Compute the fixed overhead budget and volume variances.

Overhead Variances and Under- or Overapplied Overhead Cost

The sum of the overhead variancesequals the under- or overapplied

overhead cost for a period.

Favorablevariances are equivalentto overapplied overhead.

Unfavorablevariances are equivalent

to underapplied overhead.
