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
