Topic Objectives
KAL1013 Chapter Eleven 3
Outline The usage of standard costing
Setting of standard cost and types of
standard
Calculation of variance: Direct material
Direct labor
Factory overhead
KAL1013 Chapter Eleven 4
Standard Costing The cost that has been pre-determined after considering other factors.
Those are estimated costs which are considered to be ideal for each of the cost component ( direct
material, direct labor and factory overhead ).
The standard cost system enable the management to determine how much a product should cost.
KAL1013 Chapter Eleven 5
The usage of standard costing Planning and controlling:
Product costing:
Compare actual cost & budgeted cost
Improve performance
Increase efficiency
Provide readily available unit cost
information
KAL1013 Chapter Eleven 6
Setting of Standard Cost
Analysis on the historical cost experience:Provide initial guidelines for standard setting
Engineering studies:Determine the most efficient way to operate
Input from operating personnel:Accountable for meeting the standards
Involve joint efforts on:
KAL1013 Chapter Eleven 7
Types of Standards Ideal standard
Normal standard
Maximum efficiency
Can be achieved if everything operates perfectly.
Currently attainable standard
Allowance is made for breakdown, interruptions etc..
KAL1013 Chapter Eleven 8
Variance Analysis
Variances are the difference between the actual manufacturing cost and the standard cost at the actual level of production.
The significance of the variance for each element in manufacturing cost needs further analysis to determine the corrective actions.
KAL1013 Chapter Eleven 9
Calculation of variance
Direct material
Direct labor
Factory overhead
KAL1013 Chapter Eleven 10
Standard Cost

KAL1013 Chapter Eleven 14
Direct Material Variance
Direct Material Price Variance
Direct Material Usage (Quantity) Variance
To measure the difference between the actual cost and the standard cost of direct materials.
KAL1013 Chapter Eleven 15
1. Direct material price variance
(Actual Price x Actual Quantity) - (Standard Price x Actual Quantity)
Simplified to be:
Actual Quantity (Actual Price – Standard Price)
AQ ( AP – SP )
KAL1013 Chapter Eleven 16
2. Direct material usage (quantity) variance
(Standard Price x Actual Quantity) - (Standard Price x Standard Quantity)
Simplified to be:
Standard Price (Actual Quantity – Standard Quantity)
SP ( AQ – SQ )
KAL1013 Chapter Eleven 17
Actual Price x Actual Qty Std Price x Actual Qty Std Price x Std Qty

Direct material variance
KAL1013 Chapter Eleven 18
Illustration 2
The followings are the actual price and quantity for direct material used by the company in producing 10,000 bottles of peanut butter:
Actual Price Actual Quantity
Peanut RM2.70/kg 1,400kg
Butter RM2.505/kg 1,200kg
Sugar RM1.18/kg 2,300kg
KAL1013 Chapter Eleven 19
Direct material price variance:
Peanut: 1,400 (2.70 – 2.80) = 140 (F)
Butter: 1,200 (2.505 – 2.70) = 234 (F)
Sugar: 2,300 (1.18 – 1.20) = 46 (F)
420 (F)
AQ ( AP – SP )
KAL1013 Chapter Eleven 20
Direct material usage variance:
Peanut: 2.80 (1,400 – 1,500) = 280 (F)
Butter: 2.70 (1,200 – 1,000) = 540 (U)
Sugar: 1.20 (2,300 – 2,500) = 240 (F)
20 (U)Therefore ,
Total direct material variance = 420 (F) + 20 (U)
= 400 (F)
SP ( AQ – SQ )
KAL1013 Chapter Eleven 21
Direct Labor Variance
Direct Labor Rate Variance
Direct Labor Efficiency Variance
Measures the differences between the actual cost and the cost that suppose to be paid to the labor.
KAL1013 Chapter Eleven 22
1. Direct Labor Rate Variance
(Actual Hour x Actual Rate) - (Actual Hour x Standard Rate)
Simplified to be:
Actual Hour ( Actual Rate – Standard Rate )
AH ( AR – SR )
KAL1013 Chapter Eleven 23
2. Direct Labor Efficiency Variance
(Standard Rate x Actual Hour) - (Standard Rate x Standard Hour)
Simplified to be:
Standard Rate ( Actual Hour – Standard Hour )
SR ( AH – SH )
KAL1013 Chapter Eleven 24
Actual Hour x Actual Rate Std Hour x Actual Rate Std Hour x Std Rate
Rate Variance Efficiency Variance
Direct Labor Variance
KAL1013 Chapter Eleven 25
Illustration 3:
The followings are actual rate and labor hour in the production of 10,000 bottles of peanut butter:
Actual labor rate Actual labor hour
Machine operator RM3.90/hour 190 hours
Packaging RM2.81/hour 110 hours
KAL1013 Chapter Eleven 26
Direct Labor Rate Variance:
Machine Operator: 190 (3.90 – 4.00 ) = 19 (F)
Packaging: 110 (2.81 – 3.00) = 21 (F)
40 (F)
AH ( AR – SR )
KAL1013 Chapter Eleven 27
Direct Labor Efficiency Variance:
Machine Operator: 4.00 (190 – 200) = 40 (F)
Packaging: 3.00 (110 – 100) = 30 (U)
10 (F)
SR ( AH – SH )
Therefore,
total direct labor variance: = 40 (M) + 10 (M)
= 50 (M)
KAL1013 Chapter Eleven 28
Factory Overhead Variance
Factory Overhead Flexible Budget Variance
Factory Overhead Volume Variance
Measures the differences between the actual cost and the supposed related cost of factory overhead.
KAL1013 Chapter Eleven 29
1. Factory Overhead Flexible Budget Variance
Actual Overhead Costs - Flexible Overhead Costs
Flexible OH Costs = Variable OH + Fixed OH
= (Variable OH rate x Actual production) +
(Fixed OH rate x Standard production)
KAL1013 Chapter Eleven 30
2. Factory Overhead Volume Variance
Flexible OH Costs - Standard OH at actual production
Standard OH at actual production
= Variable OH + Fixed OH
Variable OH rate x Actual production=
+ Fixed OH rate x Actual production
KAL1013 Chapter Eleven 31
Actual OH Costs Flexible OH Costs Std OH at actual prod.

KAL1013 Chapter Eleven 32
Illustration 4
The followings are the actual factory OH costs incurred in producing 10,000 unit / bottles of peanut butter:
Variable OH costs RM560
Fixed OH costs RM1,440
Note: Standard fixed OH costs per unit is calculated based on normal capacity of 12,000 units.
KAL1013 Chapter Eleven 33
Flexible budget variance:
Variable OH:
Actual cost - (Std OH per unit x actual production )
560 - (0.05 x 10,000)
60 (U)
=
=
Fixed OH : Actual cost - (Std OH per unit x std production )
=
= 1,440 - (0.12 x 12,000)
0
Total flexible budget variance = 60 (U)
KAL1013 Chapter Eleven 34
Production volume variance:
Variable OH :
Flexible OH costs - (Std OH per unit x actual production )
500 - (0.05 x 10,000)
0
=
=Fixed OH :
Flexible OH costs - (Std OH per unit x actual production )
=
= 1,440 - (0.12 x 10,000)
240 (U)
Total production volume variance = 240 (U)
KAL1013 Chapter Eleven 35
Total factory OH variance :
Flexible budget variance + Production volume variance
= 60 (U) + 240 (U)
= 300 (U)
