ABC ltd is a circuit board producer and produces two products, L1 & L2. The company currently uses traditional costing system for making business decisions. However, recently the company is considering a move towards the Activity-Based Costing (ABC) system. As one of the company’s accountant’s you have been asked to prepare a statement comparing both the costing methods for the next company board meeting. Your supervisor has given you the following quarterly data: -
Total Indirect Costs for the quarter:
Assembly RM630,000 Soldering RM270,000 Inspection RM160,000
L1 L2
Direct costs (materials, labour) RM162,400 RM178,240
Machine hours (assembly) 480 1,080
Number of units produced (soldering) 6,000 4,000
Testing hours (inspection) 6,000 8,000
In the traditional system, the Inspection department (support department) and its costs were shared by the Assembly and Soldering departments (production departments) i.e. 60% cost allocated to Assembly and 40% cost allocated to Soldering.
Under the traditional system, calculate the following: Manufacturing cost per unit for L1 and L2
L1 RM97.697; L2 RM203.614
L1 RM203.614; L2 RM97.697
L1 RM200,400; L2 RM133.600
None of the above
Answer: L1 RM97.697 ; L2 RM203.614 |
Calculation:
1. Overhead cost
Particulars | Assembly | Soldering |
Overhead cost | RM630,000 | RM270,000 |
Inspection cost (RM160,000 * 60%) (RM160,000 * 40%) | RM96,000 | RM64,000 |
Total Overhead cost | RM726,000 | RM334,000 |
2. Predetermined overheads rate
Predetermined overhead rate = Total Overhead cost / Total Base quantity
Assembly
Overhead cost = RM726,000
Total Machine hours = 480 + 1,080 = 1,560
Assembly = RM726,000 / 1,560 machine hours = RM465.38 per machine hours
Soldering
Overhead cost = RM334,000
Total number of units = 6,000 + 4,000 = 10,000
Soldering = RM334,000 / 10,000 units = RM33.40 per unit
3. Allocation of overhead cost to product
L1 = (480 machine hours * RM465.38) + (6,000 Units * RM33.40) = RM423,782
L2 = (1,080 machine hours * RM465.38) + (4,000 Units * RM33.40) = RM636,210
4. Manufacturing cost per unit
Particulars | L1 | L2 |
Direct cost (materials, labour) | RM162,400 | RM178,240 |
Indirect cost (overhead cost) | RM423,782 | RM636,210 |
Total manufacturing cost | RM586,182 | RM814,450 |
/ Number of Units | 6,000 | 4,000 |
Manufacturing cost per unit | RM97.697 | RM203.614 |
All the best...
