  1. Chapter 6Cost Allocation and Activity-Based Costing

  2. Presentation Outline • Purposes of Cost Allocation • The Process of Cost Allocation • Activity Based Costing

  3. I. Purposes of Cost Allocation • To Provide Information for Decision Making • To Reduce Frivolous Use of Common Resources • To Encourage Evaluation of Services • To Provide “Full” Cost Information

  4. A. To Provide Information for Decision Making From a decision making standpoint, the allocated cost should measure the opportunity cost of using a company resource.

  5. B. To Reduce Frivolous Use of Common Costs By not allocating costs, resources may appear “free” to users. However, resources never come with zero costs.

  6. C. To Encourage Evaluation of Services Users of services should consider the possibility of lower cost alternative. This is unlikely to be considered if costs are not allocated to the user.

  7. D. To Provide “Full” Cost Information • GAAP requires full-costing for external reporting purposes. • In the long run, all costs must be covered.

  8. II. The Process of Cost Allocation • The Steps of Cost Allocation • Arbitrary Approaches to Cost Allocation • Allocating Service Department Costs • Problems with Cost Allocation

  9. A. The Steps of Cost Allocation • Determine the Cost Objective (Cost Object). • Form Cost Pools • Select an Allocation Base to Relate the Cost Pools to Cost Objects

  10. 1. Identifying the Cost Objective (Cost Object) Determine the product, service, department, etc., that is to receive the allocation.

  11. 2. Form Cost Pools A cost pool is a grouping of individual costs, the sum of which is allocated using a single allocation base. Cost pools include: • Departments (i.e., maintenance or personnel departments) • Major Activities (i.e., equipment setups)

  12. 3. Select an Allocation Base to Relate the Cost Pools to Cost Objects • It is very important that the allocation base relates the cost pool to the cost object. • Allocation should be based on a cause and effect relationship between costs and cost objects. • If cause and effect cannot be established, other approaches are used.

  13. B. Arbitrary Approaches to Cost Allocation • Relative benefits approach – cost should be allocated in accordance with the cost objects that benefit the most from the cost. • Ability to bear costs – cost should be allocated to cost objects in proportion to profitability. • Equity approach – allocate costs in a method that is perceived to be fair and equitable.

  14. C. Allocating Service Department Costs • Manufacturing areas are often organized by (1) production departments directly involved in the manufacturing process, and (2) service departments that provide assistance to production departments. • In order to avoid passing on inefficient cost control of service departments to production departments, budgeted rather than actual service department costs should be allocated to production departments. See illustration on pages 195-196

  15. D. Problems with Cost Allocation • Managers may be evaluated on the basis of costs beyond their control. • Allocations of fixed costs make them appear as variable. • Use of only volume related allocation bases are inappropriate for costs that are not affected by volume. This can result in low volume items being undercosted, while high volume items are overcosted.

  16. III. Activity Based Costing (ABC) • The ABC Approach • Pros and Cons of ABC • Activity Based Management (ABM) • An Illustration of ABC

  17. A. The ABC Approach • Identify the major activities that cause overhead costs to be incurred. • Group costs of activities into cost pools. • Identify measures (allocation bases) of activities (the cost driver). • Relate costs to products using the cost drivers.

  18. B. Pros and Cons of ABC • ABC is less likely than traditional costing to undercost or overcost products. • ABC may lead to improvements in cost control (thru ABM) • ABC can be expensive since data regarding numerous allocation bases must be collected.

  19. C. Activity Based Management (ABM) • Determine major activities • Identify resources used by each activity • Evaluate the performance of the activity (benchmark against similar activities at other places) • Identify ways to improve the efficiency and/or effectiveness of the activities (compare to best practices at other places)

  20. D. An Illustration of ABC

  21. Combining Activity Cost Pools • Unit-level activities – Performed each time a unit is produced. Example: Machine power. • Batch-level activities – Performed each time a batch is produced. Example: Setup costs. • Product-level activities – Relates to a certain product regardless of runs or batches. Example: Product design • Organization-sustaining activities – Activities independent of customers or products. Example: Providing a computer network.

  22. A Traditional Overhead Calculation Gardenrite Co. manufactures 85,000 units of a Spade and 800 units of a Mower. The company currently uses direct-labor cost to assign overhead costs to products. The company estimates that it will incur $40,000,000 in manufacturing overhead and estimates that labor cost will be $8,000,000. Compute the predetermined overhead rate. $40,000,000 $8,000,000 $5 per labor dollar =

  23. Direct materials $1.80 Direct labor 1.08 Direct materials $60.00 Direct labor 15.00 A Spade uses $1.08 direct-labor cost per unit while a Mower uses $15.00 direct-labor cost per unit. Use the following information to compute each product’s total unit cost: Spade Mower Mfg. Overhead 1.08 DL$ x $5 = 5.40 $8.28 Mfg. Overhead 15 DL$ x $5 = 75.00 $150.00

  24. Expand the number of indirect-cost pools until each of these pools is homogeneous.

  25. Identify the preferred cost-allocation base (cost driver) for each indirect cost pool. Number of Setups Number of Material Requisitions Number of Machine Hours Number of Workstations Used

  26. The First Stage Allocation Overall Overhead Cost Pool $40,000,000 Setup Costs $4,000,000 Material Handling $2,000,000 Equipment Deprec. $10,000,000 Other $24,000,000

  27. Manufacturing Activities

  28. The Second Stage Allocation - Spades Machine Setups $4,000,000/ 1,000 = $4,000 Material Req. $2,000,000/ 2,000 = $1,000 Machine Hours $10,000,000/ 20,000 = $500 Work- stations $24,000,000/ 3,000 = $8,000 $4,000 x 2 $8,000 $1,000 x 3 $3,000 $500 x 40 $20,000 $8,000 x 1 $8,000 $39,000 $39,000 / 85,000 units = 0.46 per unit

  29. The Second Stage Allocation - Mowers Machine Setups $4,000,000/ 1,000 = $4,000 Material Req. $2,000,000/ 2,000 = $1,000 Machine Hours $10,000,000/ 20,000 = $500 Work- stations $24,000,000/ 3,000 = $8,000 $4,000 x 5 $20,000 $1,000 x 50 $50,000 $500 x 100 $50,000 $8,000 x 15 $120,000 $240,000 $240,000 / 800 units = $300 per unit

  30. Spade (85,000 units) Direct materials $1.80 Direct labor 1.08 Mfg overhead 5.40 Unit cost $8.28 Mower (800 units) Direct materials $ 60.00 Direct labor 15.00 Mfg overhead 75.00 Unit cost $150.00 Product Unit Cost Comparison Traditional Costing Activity-Based Costing Spade (85,000 units) Direct materials $1.80 Direct labor 1.08 Mfg overhead .46 Unit cost $3.34 Mower (800 units) Direct materials $ 60.00 Direct labor 15.00 Mfg overhead 300.00 Unit cost $375.00
