Setting Standards – Direct Materials

In some manufacturing processes, a certain amount of defective production or spoilage is normal.

Example: 1,000 liters of chemicals are normally required in a chemical process in order to obtain 800 liters of good output. If total good output in February is 5,000 liters, what is the standard allowed quantity

of input?

Good output quantity = 80% X Input quantity

Good output quantity ÷ 80% = Input quantity allowed

5,000 liters of goodoutput ÷ 80%

= 6,250 liters of input allowed

Using Standard-Costing Systems for Control

Favourable VariancesVariances are either favourable or adverse (unfavourable)

Favourable variances impact favourably on the profitExpense:when actual expenses is less than standardexpense, the variance is favourable

Revenue:when actual revenue is greater than standard revenue, the variance is favourable

Unfavourable VariancesUnfavourable or adverse variances impact

unfavourably on the profit

Expense:when actual expenses is greater than standardexpense, the variance is unfavourable

Revenue:when actual revenue is less than standardrevenue, the variance is unfavourable

Unfavourable Variances

Unfavourable variances measure a business's failure to meet its plans and large unfavourablevariances represent large failures.

It is worthwhile reporting a variance to a manager only if that manager can exercise some control over the cost (or revenue) being reported.

Broadly controllable costs should be those which the manager is responsible for budgeting.

Control through Management by ExceptionVariance analysis is a tool for alerting management to the fact that there are problems and narrowing down the sources.

It directs the scarce resource of management time to the areas where it is most needed.

The practice of using the variance analysis in this manner is called management by exception (MBE).

MBE refers to the process of delegating all routine functions by means of procedures and focusing management attention on only those items which fall outside those procedures.

and when to ignore it?

Standard Cost Variances

Cost Variance Analysis

Basic ConceptsA budget relates to the cost for the total activity, whereas standard relates to a cost per unit of activity.Static (Master) Budget – is based on the output planned at the start of the budget periodStatic-Budget Variance (Level 1) – the difference between the actual result and the corresponding static budget amountFavorable Variance (F) – has the effect of increasing operating income relative to the budget amountUnfavorable Variance (U) – has the effect of decreasing operating income relative to the budget amount

VariancesVariances may start out “at the top” with a Level 1 analysis. This is the highest level of analysis, a super-macro

view of operating results. The Level 1 analysis is nothing more than the difference between actual and static-budgetFurther analysis decomposes (breaks down) the Level 0 analysis down into progressively smaller and smaller components Answers: “How much were we off?”

Levels 2, and 3 examine the Level 1 variance into progressively more-detailed levels of analysis Answers: “Where and why were we off?”

Flexing variable costsThe variable costs can be calculated using the

original budget information but when this is not available, the budgeted variable costs are

adjusted in direct proportion to the change in volume. The new variable cost for each item can be determined

by dividing the budget cost (variable)by budget volume (to get cost per unit) and then multiplying by actual

volume

Standard Quantities allowedThe following information applies to a vehicle

production plant:

Budgeted production = 1,000 vehiclesBudgeted quantity of tyres per vehicle = 5Actual production = 960 vehiclesActual quantity of tyres that were used = 4,850Calculate:a) Budgeted quantity of tyres that could be usedb) Standard quantity of tyres that should have

been used for the actual production

1,000 x 5 = 5,000b) Standard quantity of tyres that should have

Level 1 Analysis, Illustrated

Flexible BudgetFlexible Budget – shifts budgeted revenues and costs up and down based actual operating results (activities)Represents a blending of actual activities and budgeted dollar amountsWill allow for preparation of Level 2 and 3 variances Answers the question: “Why were we off?”

Level 2 Analysis, Illustrated

Level 2 VariancesWhat might have caused the sales-volume variance? Demand is not growing Competitors are taking market share The firm did not adapt its products to customer

preferences Quality problemsWhat causes flexible budget variances? Change in selling price Using more inputs (material and labor) than expected The inputs had a higher price per unit than expected

Level 3 VariancesDeals with the variances of cost items (e.g. labor, material and overhead).

What caused Koala to spend more than theanticipated amount on direct material?

First, the company purchased fabric at a higher price ($8.15 persquare meter) than the standard price ($8.00 per square meter).

Direct-material price variance = (PQ X AP) - (PQ X SP) = PQ(AP - SP) where: PQ = Quantity purchased

AP = Actual priceSP = Standard price

Koala’s direct- material price variance for June is computed as follows:Direct-material price variance = PQ(AP - SP)= 40,000 ($8.15 - $8.00) = $6,000 unfavorable

Direct-Material Variances

Second, the company used more fabric than the standard price. (36,400 sq. meters actually used, Instead of the standard amount of 36,000 sq. meters)

Direct-material quantity variance =(AQ X SP) - (SQ X SP) = SP(AQ - SQ) where:

AQ = Actual quantity used SQ = Standard quantity allowed

Koala’s direct- material quantity variance for June

=$3,200 unfavorable

Koala’s direct- material quantity variance for June is computed as follows:

Direct-material quantity variance = SP(AQ - SQ)= $8.00(36,400 - 36,000)

Analysis of Direct-Labour Variances

What caused Koala to spend more than theanticipated amount on direct labor?

Direct instead of the standard amount of $18 per hrFirst, the company incurred a cost of $19 per hour for

Direct labour instead of the standard amount of $18 per hr

Direct-labor rate variance = (AH X AR) - (AH X SR) =

SR = Standard rate per hour

Direct-labor rate variance = (AH X AR) - (AH X SR) =AH(AR - SR) where:

AH = Actual hours used AR = Actual rate per hour

SR = Standard rate per hour

Koala’s direct-labor rate variance for June is computed as follows:

Direct-labor rate variance = AH(AR - SR)= 5,900 ($19 - $18)

=$5,900 unfavorable

Direct-Labour Variances

Koala used only 5,900 hours of direct labour, which is <

offset the unexpectedly high wage rate.

Koala used only 5,900 hours of direct labour, which is < standard quantity of 6,000 hours, given actual output of

3,000 tents. The increased efficiency does not fully offset the unexpectedly high wage rate.

Direct-labour efficiency variance = (AH X SR) - (SH X SR) =

SH = Standard hours allowed

Direct-labour efficiency variance = (AH X SR) - (SH X SR) =SR(AH - SH) where:

AH = Actual hours used SH = Standard hours allowed

Koala’s direct - labour efficiency variance for June is computed as follows:

Direct - labor efficiency variance = SR(AH - SH)= $18 (5,900 - 6,000) = $1,800 favorable

When there are several types of direct material or direct labour, price and quantity variances are computed for

each type, and then added to obtain a total price variance and a total quality variance

Multiple Types Of Direct Material Or Direct Labour

Mix and yield variances

The quantity variance can be sub-divided into a mixture variance and a yield variance where more than one type of raw material is used for the manufacture of a product. The total of the two latter variances should however add up to the quantity Variance.

organization than one that is not

Favorable VariancesIt is as important to

investigate significant favorable variances as well as

significant unfavorable variances

Cost and Benefits of Investigation

The decision whether to investigate a variance is a

Behavioural Effects Of Standard Costing

individuals and departments

They can profoundly influence behavior whenthey are used to determine salary increases,

bonuses, and promotions

Generally results from using a different mix of employees than that anticipatedwhen the standard were set

Motivating employees toward production goals and effective work schedulesimproves efficiency

expense accounts, and

they are closed out at the end of the
