3 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-3 Traditional Costing Systems Traditional cost systems were created when manufacturing processes were labor intensive. A single company-wide overhead rate based on direct labor hours may be used to allocate overhead to products in these labor intensive processes.

4 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-4 In this example, overhead will be allocated to jobs using direct labor hours. If total overhead is $120, how much will be allocated to each job? In this example, overhead will be allocated to jobs using direct labor hours. If total overhead is $120, how much will be allocated to each job? Traditional Costing Systems

5 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-5 Overhead Rate = $120 ÷ 8 direct labor hours Overhead Rate = $15 per direct labor hour Job 1 = 2 hours × $15 per hour = $30 Job 2 = 6 hours × $15 per hour = $90 Traditional Costing Systems

6 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-6 The company introduces automated machinery. Total overhead rises from $120 to $420, while the labor time needed for Job 2 falls from 6 hours to 1 hour. Now allocate the $420 overhead to the two jobs. Traditional Costing Systems

7 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-7 Overhead Rate = $420 ÷ 3 direct labor hours Overhead Rate = $140 per direct labor hour Job 1 = 2 hours × $140 per hour = $280 Job 2 = 1 hour × $140 per hour = $140 Traditional Costing Systems

8 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-8 Is this a reasonable costing method? Automation benefited only Job 2, but most of the additional overhead cost was allocated to Job 1. Clearly, we need to look for another cost driver. Traditional Costing Systems

24 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-24 Since customers are charged “per call”, the proper activity in this case is the number of calls handled by the center. The cost-driver rate would be: $1,260,000 ÷ 120,000 units = $10.50 per call Since customers are charged “per call”, the proper activity in this case is the number of calls handled by the center. The cost-driver rate would be: $1,260,000 ÷ 120,000 units = $10.50 per call  Calculate Cost-Driver Rates for Activities

McGraw-Hill/Irwin 4-25  Calculate Cost-Driver Rates for Activities Appropriate cost-driver base Based on resource’s practical capacity to support activities Cause and effect relationship between activity and costs Measurable Predict or explain an activity’s use of resources

26 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-26 Practical Capacity Note When estimating the cost of an activity, only the costs associated with the product should be used (practical capacity). The cost of “unused capacity” should not be applied to products. EXAMPLE Suppose we rent a 1,000 square foot warehouse for $1,000 per month. Only 800 sq. ft. are used to store Product A. The rest of the warehouse is “unused”. How much rent cost should be allocated to Product A? EXAMPLE Suppose we rent a 1,000 square foot warehouse for $1,000 per month. Only 800 sq. ft. are used to store Product A. The rest of the warehouse is “unused”. How much rent cost should be allocated to Product A?

27 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-27 20%, or $200 should be assigned to “unused capacity” 80%, or $800 should be assigned to Product A Practical Capacity Note

29 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-29  Assign Activity Costs to Products 1. Identify all the activities related to a given product or service. 2. Determine how many units of each activity are used per unit of product. 3. Assign costs to products using the cost- driver rates for each activity.

30 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-30 Example: Yazz, Inc. produces 130,000 units of Product A and 400,000 units for Product B. Using the following cost information, how much overhead should be allocated to Product A?  Assign Activity Costs to Products

32 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-32 Let’s look at an example from the Bilson Company. Activity-Based Costing Example

33 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-33 Bilson, Inc. manufactures and sells 5,000 units of Product A (deluxe model), and 25,000 units of Product B (standard model) each year. Product A requires 3.0 direct labor hours (DLH) and Product B requires 2.5 DLH to produce. Employing a traditional costing system, Bilson assigns overhead cost to products using direct labor hours. The predetermined overhead rate is: Bilson, Inc. manufactures and sells 5,000 units of Product A (deluxe model), and 25,000 units of Product B (standard model) each year. Product A requires 3.0 direct labor hours (DLH) and Product B requires 2.5 DLH to produce. Employing a traditional costing system, Bilson assigns overhead cost to products using direct labor hours. The predetermined overhead rate is: Mfg. overhead cost Direct labor hours = $1,550,000 77,500 =$20/DLH Activity-Based Costing Example

34 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-34 Bilson’s unit product costs using traditional costing are: Bilson marks its products up by 50 percent and allocates its $500,000 customer service costs based on revenue. Activity-Based Costing Example

35 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-35 $975,000 ÷ ($975,000 +$3,900,000) × $500,000 Traditional Costing $130.00 × 1.50 Activity-Based Costing Example

36 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-36 Sales of Product A have increased steadily since introduction, but company income has declined. Management at Bilson is unhappy with the traditional costing system and they have decided to try activity-based costing. In addition, management has observed that the cost of direct labor is relatively stable. Since labor does not behave like a unit-level cost, labor will be combined with overhead and the total conversion cost will be assigned using ABC. Activity-Based Costing Example

37 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-37 The total conversion cost is: Traditional overhead $1,550,000 Labor (77,500 hours @ $10) 775,000 Total$2,325,000 The total conversion cost is: Traditional overhead $1,550,000 Labor (77,500 hours @ $10) 775,000 Total$2,325,000 In addition, management has observed that the cost of direct labor is relatively stable. Since labor does not behave like a unit-level cost, labor will be combined with overhead and the total conversion cost will be assigned using ABC. Activity-Based Costing Example

38 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-38 Management has identified the following five activities and costs in the production of its two products: Total conversion cost Activity-Based Costing Example

39 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-39 The following transaction data has been complied by management of Bilson: Activity-Based Costing Example

40 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-40 These data can be used to develop predetermined cost-driver rates for each of the five activities: $ 800,000 ÷ 5,000 Machine setups = $160.00 per setup Activity-Based Costing Example

41 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-41 The activity-based overhead rates we just calculated can be used to assign conversion costs to Bilson’s two products. Activity-Based Costing Example

42 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-42 The activity-based overhead rates we just calculated can be used to assign conversion costs to Bilson’s two products. Activity-Based Costing Example

43 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-43 The activity-based overhead rates we just calculated can be used to assign conversion costs to Bilson’s two products. Activity-Based Costing Example

44 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-44 Let’s compute the product cost for A and B using our ABC overhead rates: These amounts did not change as a result of using ABC. Activity-Based Costing Example

45 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-45 Now compare the unit product costs using the traditional costing system and our ABC system. Remember, we used one overhead rate based on direct labor hours. Activity-Based Costing Example

46 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-46 Now compare the unit product costs using the traditional costing system and our ABC system. Adopting activity-based costing usually results in a shift of batch-level and product-level overhead costs from high-volume standard products to low-volume, more complex products. Activity-Based Costing Example

47 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-47 Can you see how different allocation methods might lead to making different management decisions? Now compare the unit product costs using the traditional costing system and our ABC system. Activity-Based Costing Example

48 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-48 Based on these results Bilson also decides to use ABC to assign its $500,000 customer service costs. The applicable activity is number of customer consultations. Customers buying Product A, the deluxe model, require more consultations than those buying Product B, the standard model. Cost per consultation = $500,000 ÷ 125,000 consultations = $4.00 Activity-Based Costing Example

49 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-49 ABC Costing No change in sales price Let’s compare product income using traditional and ABC costing. Activity-Based Costing Example

51 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-51 Learning Objective 6

52 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-52 Should Bilson increase the price of Product A? Should Bilson reduce the price of Product B? Should Bilson drop Product A? Product Profitability Now that we have measured product costs accurately, we see how profitable each product really is.

53 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-53 The price of Product A, the deluxe model, should probably be increased. Customers who buy deluxe models may buy based on features instead of price. The price of Product B, the standard model, may be too high. Customers who buy standard models are price sensitive. Decreasing the price would increase volume, possibly resulting in more income. Product Profitability

54 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-54 Customer Profitability What are the costs and benefits of serving specific customers? Activity-based analysis can be used to track the costs of serving customers and those customers’ contribution to company profits. Service calls Buy/sell orders Order changes

55 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-55 Estimating Costs of New Products Apply ABC analysis of present product lines to proposed new products. This is valid as long as the activities involved with the new products are similar to those for the present products.

58 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-58  More accurate and informative product costs lead to better pricing decisions.  The activities driving costs are more accurately measured.  Managers gain easier access to the relevant costs.  More accurate and informative product costs lead to better pricing decisions.  The activities driving costs are more accurately measured.  Managers gain easier access to the relevant costs. An ABC system is very expensive to develop and implement, and very time-consuming to maintain. ABC– Benefits and Limitations

59 Copyright © 2008 The McGraw-Hill Companies, Inc. All rights reserved. McGraw-Hill/Irwin 4-59 When Should a Company Use ABC? Indirect costs are significant in proportion to direct costs. Goods are complex, requiring many inputs and processes. Complex, low-volume products are profitable while standard, high-volume products are not. Different departments believe costs are assigned inaccurately. The company loses bids it thought were low, and wins bids it thought were high. Operations have changed significantly, but the costing system has not changed. Introduction of new models result in higher sales, apparent profits per unit, but an overall income decline.
