STANDARD COSTING

By SUPRIYA SEHGAL

1

STANDARD COSTING SYSTEM The management evaluates the performance of a company by comparing it with some predetermined measures

Therefore, it can be used as a process of measuring and correcting actual performance to ensure that the plans are properly set and implemented

2

PROCEDURES OF STANDARD COSTING SYSTEM Set the predetermined standards for sales margin and production costs

Collect the information about the actual performance

Compare the actual performance with the standards to arrive at the variance

Analyze the variances and ascertaining the causes of variance

Take corrective action to avoid adverse variance

Adjust the budget in order to make the standards more realistic

3

FUNCTIONS OF STANDARD COSTING SYSTEM Valuation Assigning the standard cost to the actual output

Planning Use the current standards to estimate future sales volume and

future costs

Controlling Evaluating performance by determining how efficiently the current

operations are being carried out

4

Motivation Notify the staff of the management’s expectations

Setting of selling price

5

VARIANCE6

VARIANCE ANALYSIS

A variance is the difference between the standards and the actual performance

When the actual results are better than the expected results, there will be a favourable variance (F)

If the actual results are worse than the expected results, there will be an adverse variance (A)

COST VARIANCE11

COST VARIANCE

12

•Cost variance = Price variance + Quantity varianceCost variance is the difference between the standard cost and the Actual cost

•Price variance = (standard price – actual price)*Actual quantity A price variance reflects the extent of the profit change resulting from the change in activity level

•Quantity variance = (standard quantity – actual quantity)* standard cost

A quantity variance reflects the extent of the profit change resulting from the change in activity level

THREE TYPES OF COST VARIANCE Material cost variance


Variable overheads variance

13

MATERIAL AND LABOUR VARIANCE

14

MATERIAL COST VARIANCE Material price variance

= (standard price – actual price)*actual quantity

Material usage variance

= (Standard quantity – actual quantity)* standard price

= (Standard quantity for actual production – actual quantity production) * standard price

15

LABOUR COST VARIANCE



Labour efficiency variance= (standard quantity – actual quantity)*standard price= Standard quantity for actual production – actual quantity used) *

standard price

ABC Ltd. makes and sells a single product. The company uses a Standard marginal costing system. It plans to produce and sell 1000 units in May 2005. A budget statement is produced as follow:

Budgeted income statement for the month ended 31 May 2005$ $

Sales ($50*1000) 50000Less: Variable cost of goods sold

Direct materials ($3*4000) 12000Direct labour ($5*3000) 15000Variable overheads ($2*3000) 6000 33000

Budget contribution 17000Fixed overhead 3000Budget profit 14000

19

The actual sales and production is 800 units. The actual income statement is shown as follows:

Income statement for the month ended 31 May 2005$ $


Direct materials ($3.2*2400) 12000Direct labour ($6*3200) 15000Actual Variable overheads 5500 32380

Material cost variance

Material price variance


= ($3 - $3.2)*2400

= $480 (A) Material usage variance

= (Standard quantity – actual quantity)* standard price

= (Standard quantity for actual production – actual quantity production) * standard price

= (4*800 – 2400)*$3

= $2400 (F)

Material usage variance $2400 (F)

Total Material cost variance $1920 (F)

= ($5 - $6)*3200

Labour efficiency variance= (standard quantity – actual quantity)*standard price

= Standard quantity for actual production – actual quantity used) * standard price

= (3* 800 – 3200)*$5

OVERHEADS VARIANCE

OVERHEADS VARIANCE


Fixed overheads variance

25

VARIABLE OVERHEADS VARIANCE Variable overheads variance is the difference between the standard variable overheads absorbed into the actual output and the actual overheads incurred

CALCULATION ON OVERHEAD ABSORBED Step 1

Step 2

28

POAR = Budgeted overheads

Budgeted activity level in standard hours

Overhead absorbed = POAR * Standard hours for actual number of units produced

VARIABLE OVERHEADS VARIANCE


= variable overheads absorbed – actual variable overheads incurred

Variable overheads expenditure variance

= standard variable overheads for actual hours worked – Actual variable overheads incurred

Variable overheads efficiency variance

= Standard variable overheads for standard hours of output – Actual variable overhead absorbed

= (standard hours for actual output – Actual hours worked)* standard price 29

33

POAR = Budgeted overheads

Budgeted activity level in standard hours

Overhead absorbed = POAR * Standard hours for actual number of units produced

= $2 *3 hr per unit * 800 units

= $6000 3000

= $2

Standard hr per unit = 3000 hr /1000 units



= variable overheads absorbed – actual variable overheads incurred

= $4800 - $5500

= $700 (A)

Variable overheads expenditure variance

= standard variable overheads for actual hours worked – Actual variable overheads incurred

= ($2* 3200 hr) - $5500

= $900 (F)34

Variable overheads efficiency variance

= Standard variable overheads for standard hours of output – Actual variable overhead absorbed

= (standard hours for actual output – Actual hours worked)* standard price

= (3 hr *800 units – 4 hr *800 units)*$2

= $1600 (A)

35

Actual hour per unit = $3200 hr/800 units


Variable overheads expenditure variance $900 F

FO VARIANCE IN MARGINAL AND ABSORPTION COSTING In marginal costing: Fixed overheads are charged as period costs instead of charging to

product in marginal costing. It is assumed that the fixed overheads remain unchanged with the

change in the level of activity. Single fixed overhead expenditure variance will be used

56

In absorption costing Fixed overheads are charged to the products and included in the

valuation of closing stock. Total fixed overheads variance is divided into fixed overheads price

variance and fixed overheads volume variance

57

PROFIT RECONCILIATION

STATEMENT58

PROFIT RECONCILIATION STATEMENT Profit reconciliation statement is used to sum up all variances

It can help the top management to explain the major reasons for the difference between budgeted and actual profits

The sales margin variance and fixed overheads variance are different between absorption and marginal costing system

59

REASONS FOR VARIANCES Material price variance Price changes in market conditions Change in the efficiency of purchasing dept. to obtain good terms

from suppliers Purchase of different grades or wrong types of materials

60

REASONS FOR VARIANCES Materials usage variance More effective use of materials/ wastage arising from the efficient

production process Purchase of different grade or wrong types of materials Wastage by the staff Change in production methods

61

REASONS FOR VARIANCES Labour rate variance Non-controllable market changes in the basic wage rate Use of higher/lower grade of workers Unexpected overtime allowance paid

62

Labour efficiency variance Purchase of different grade or wrong types of materials Breakdown of machinery High/low labour turnover Changes in production method Introduction of new machinery Assignment wrong type of worker to work Adequacy of supervision Changes in working condition Change in motivation methods

63

Reasons for variances

Variable overheads expenditure variance It may be caused by the non-controllable change in the price level of indirect wages or utility rates since the predetermined rate is set

It is meaningless to interpret this kind of variance on its own. One should look various components of the fixed overheads

64


Variable overheads efficiency variance Both the variable overheads and direct labour cost vary with the

direct labour hours worked

65


Fixed overheads expenditure It is meaningless to interpret this kind of variance on its own. It may be caused by the change in the price levels of rent, rates

and other fixed expenses

66


Fixed overhead volume variance When the level of activity is higher than the budgeted level, there is

a favourable variance

67


Sales margin price variance Change in the pricing strategies of the company Response to the change of pricing policies of its competitors Higher profit margin with growing demand for the product Lower profit margin for simulating sales

68


Sales margin volume variance Change in prices and demand Change in the market share of its competitiors
