Example 1
• Prime Furniture Sdn Bhd specialises in living room leather furniture
products. During the month of March, the company purchased RM105,000 of
raw materials. Direct labour hours worked during the period was 4,000
hours.The workers were paid RM10 per hour. Direct expenses (high
performance glue etc) of RM11,000 was incurred. Manufacturing overhead
for the month was RM36,000.
• Each set of leather sofa was sold for RM5,500. Prime Furniture also incurred
selling costs including sales commission of RM125,000 and administration
costs of RM18,000. Stock information for the period is as follows:
1 March 2017 31 March 2017
Raw material stock RM12,000 RM25,000
Work in process stock RM25,000 RM12,000
Finished Goods stock RM5,500 RM13,000

Required:
a) Determine the cost of raw materials consumed in
production and the prime costs.
b) Calculate the total of cost manufactured for the month of
March.
c) Calculate the cost of one set of leather sofa, assuming 75
were completed during March.
d) Prepare a cost of goods sold statement for the month of
March.
e) Prepare an income statement for the month of March.

• Second Technology Sdn Bhd specialises in computer products. During the
month of March, the company purchased RM105,000 of raw materials. Direct
labour hours worked during the period was 3,000 hours.The workers were
paid RM20 per hour. Direct expenses of RM12,000 was incurred.
Manufacturing overhead for the month was RM32,000.
• Each set of computer was sold for RM6,000. Second Technology also incurred
selling costs including sales commission of RM120,000 and administration
costs of RM10,000. Stock information for the period is as follows:
1 March 2023 31 March 2023
Raw material stock RM10,000 RM20,000
Work in process stock RM25,000 RM12,000

Semi variable costs
• Semi-variable costs have properties of both variable and fixed elements attached to the
total costs
• For semi-variable costs, the distinction between the fixed and variable costs
element is important for decision-making purposes.
• Cost estimation methods such as high-low method, scatter diagram and
regression analysis are used to separate the fixed and variable elements in
semi-variable costs.
• The high/low method is a ‘method of estimating cost behaviour by comparing the total
cost associated with two different level of outputs. The difference in costs is assumed to
be caused by the variable costs increasing, allowing unit variable costs to be calculated.
Following from this, since total costs is known, the fixed costs can be derived” (CIMA
Official Terminology).
• High/low method is a ‘method of estimating cost behaviour by comparing the total cost
associated with two different level of outputs.

Example 1
• The total cost of maintenance at Zack Sdn Bhd consists of both fixed and variable costs. The following information relates to the
last four months:
• Hours worked Total cost
• RM
• Month 1 9,300 115,000
• Month 2 9,200 113,600
• Month 3 9,400 116,000
• Month 4 9,600 116,800
• Required:
• Using the high- low method, estimate the total cost for Zack if 10,000 hours were worked in Month 5.
24/02/2025
Prof Dr Indra Devi
Solution
• Step 1
• From the previous four months costs, the following two periods are selected:
• The period with the highest volume (hours) of activity and its corresponding costs; and
• The period with the lowest level of activity and its corresponding costs
• Step 2
• The difference between the two costs at the two levels of activities will be the variable
costs.
• Step 3
• Thus, the variable costs per unit may be calculated by dividing the difference in total
costs by the difference in activity levels. Subsequently the fixed costs can be
determined by substituting the variable costs per unit into the formula, Total Costs
(TC)= Fixed Cost (FC) + (Variable Cost (VC) per unit x Volume), where total costs must
correspond to either the high level or the low level of activity.

24/02/2025
Prof Dr Indra Devi
Solution
In the example above this will be:
Hours worked
RM
Highest activity 9,600
116,800
Lowest activity 9,200
113,600
400
3,200
VC per unit = RM3200/400 = RM8
TC= FC + (VC per unit x Volume)
RM116,800= FC + (RM8 x 9600)
FC = RM116,800-RM76,800 = RM40,000.
Therefore, if 10,000 hours were worked, then the total cost for Month 5 will be:
TC= RM40,000 + RM8 x 10,000 = RM120,000
