A.B.C
• What is A.B.C?• How A.B.C is developed?
(Steps Involved)• Comparison of unit costs(A.B.C and traditional department product costing)
Developing activity Based Costing
• Step I: Identify the activities• Step II: Identify the cost drivers• Step III: Compute the cost driver rates• Step IV: Assign Cost using activity based costing

Step I: Identify the activities
• Setting up equipment• Machining• Moving materials• Inspecting products
Step II: Identify the cost drivers
Activities Cost drivers
Setting up equipment No. of set ups
Machining Machine hours
Moving materials No. Of moves
Inspecting products Inspection hours
Step III: Compute the cost driver rates
• Formula: estd. indirect cost / estd. volume of activity base
• Setting up equipment: 240000/100(setups) = 2400 per set up
• Machining: 200000/90000(machine hours) = 2.22 per mach. hr
• Inspecting: 160000/18000(inspection hours) = 8.89 per insp. Hr
• Moving materials: 120000/300(moves) = 400 per move
