Variance Analysis Exercises

Hi there,

Using the same old example from the previous posting of Standard Costing, I expanded the exercises and it looks like below

Example:

Setandet Kos Sdn Bhd manufactures mobile phone by the name of oPhone. Below is the budgeted cost information of oPhone for the month of October 2018 based on the budgeted production and sales of 5,000 units.
                            
    RM
Direct material:                                    
                             Plastic casings (10,000 kg)                       600,000
                             Wires (10,000 meters)                             120,000
                             Direct labour (8,000 hours)                      240,000
                             Variable overhead                                    100,000
                             Fixed overhead                                          60,000
The variable overhead cost is absorbed based on direct labour hours while the fixed overhead cost is absorbed based on number of units produced. The standard selling price of oPhone is RM1,200 per unit.

Calculate the standard cost for oPhone.



The actual data for the month is as follows:

Units produced and sold                          6,000
Selling price per unit                               RM1,000
Direct material:
Plastic casings purchased and used   12,500 kg@ RM58 per kg
Wires purchased and used                10,750 meters @ RM10 per meter
Direct labour                                         10,000 hours @ RM22 per hour
Variable overhead cost                           RM120,000
          Fixed overhead cost                               RM60,000


Analyse the following:

i)          Direct material price variance for plastic casings
ii)         Direct material usage variance for wires
iii)        Direct labour rate variance
iv)       Direct labour efficiency variance
v)        Variable overhead expenditure variance
vi)       Variable overhead efficiency variance
vii)      Fixed overhead expenditure variance
viii)     Fixed overhead volume variance
ix)       Sales margin price variance
x)        Sales margin volume variance
