  • ABC assigns to products based on the activities that drive those costs
    • Identifies resource-consuming activities and assigns costs to those activities
    • Allocates activity costs to products based on each product's consumption of those activities (, )
  • methods allocate overhead costs based on a single cost driver (, )
    • May lead to inaccurate product costs when overhead costs are not proportional to the chosen cost driver
  • ABC recognizes that different products consume different amounts of overhead resources
    • Provides a more accurate representation of the true cost of producing each product (customized vs. standard)
  • Steps in ABC:
    1. Identify activities that consume resources (machine setups, )
    2. Assign costs to activities based on
    3. Identify for each activity (number of setups, number of inspections)
    4. Calculate based on the total cost of each activity and the total quantity of the cost driver
    5. Assign activity costs to products based on each product's consumption of the cost driver
  • is crucial for identifying and understanding the activities that drive costs in an organization

Calculation of overhead rates

  • In ABC, overhead costs are grouped into based on the activities that drive those costs
    • Each cost pool is associated with a specific activity cost driver (machine hours, number of purchase orders)
  • are calculated for each cost pool using the estimated total cost of the activity and the estimated total quantity of the cost driver
    • Predetermined overhead rate = Estimated total cost of activityEstimated total quantity of cost driver\frac{Estimated\ total\ cost\ of\ activity}{Estimated\ total\ quantity\ of\ cost\ driver}
  • Example cost pools and :
    • (cost pool) driven by the number of setups (cost driver)
    • (cost pool) driven by the number of material moves (cost driver)
    • (cost pool) driven by the number of inspections (cost driver)
  • Calculating predetermined :
    • Machine setup cost pool: 100,000estimatedcost÷1,000estimatedsetups=100,000 estimated cost ÷ 1,000 estimated setups = 100 per setup
    • Material handling cost pool: 50,000estimatedcost÷2,500estimatedmoves=50,000 estimated cost ÷ 2,500 estimated moves = 20 per move
    • Quality inspection cost pool: 80,000estimatedcost÷4,000estimatedinspections=80,000 estimated cost ÷ 4,000 estimated inspections = 20 per inspection
  • Overhead allocation is a key component of ABC, ensuring costs are distributed accurately to products based on their resource consumption

Application of ABC vs traditional methods

  • Once predetermined overhead rates are calculated for each cost pool, they are applied to products based on each product's consumption of the activity cost driver
  • The overhead cost assigned to a product for a specific activity is calculated by multiplying the predetermined overhead rate by the quantity of the cost driver consumed by the product
    • Overhead cost assigned = Predetermined overhead rate × Quantity of cost driver consumed
  • Total overhead cost assigned to a product is the sum of the overhead costs assigned from each cost pool
  • Example application of ABC overhead rates:
    • Product A consumes 100 setups, 500 material moves, and 800 inspections
    • Machine setup cost assigned to Product A: 100persetup×100setups=100 per setup × 100 setups = 10,000
    • Material handling cost assigned to Product A: 20permove×500moves=20 per move × 500 moves = 10,000
    • Quality inspection cost assigned to Product A: 20perinspection×800inspections=20 per inspection × 800 inspections = 16,000
    • Total overhead cost assigned to Product A: 10,000+10,000 + 10,000 + 16,000=16,000 = 36,000
  • ABC provides more accurate product costs compared to traditional allocation methods
    • Assigns overhead costs based on the activities that drive those costs (machine setups, quality inspections)
    • Recognizes that products consume different amounts of overhead resources (low-volume vs. high-volume products)
    • Helps managers make better pricing, product mix, and cost reduction decisions based on more accurate cost information
