3. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 2 Cost and Cost Terminology Cost is a resource sacrificed or forgone to achieve a specific objective. An actual cost is the cost incurred (a historical cost) as distinguished from budgeted costs. A cost object is anything for which a separate measurement of costs is desired.

4. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 3 Cost and Cost Terminology Cost Accumulation – the collection of cost data in some organized way Cost Assignment: direct (a)– tracing accumulated costs that have a direct relationship to a cost object (b) – allocation of accumulated costs that have an indirect indirect relationship to a cost object

5. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 4 Learning Objective 2 Distinguish between direct costs and indirect costs.

6. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 5 Direct and Indirect Costs Direct Costs Example: Paper on which Sports Illustrated magazine is printed Indirect Costs Example: Lease cost for Time-Warner building housing the senior editors of its magazine COST OBJECT Example: Sports Illustrated magazine COST OBJECT Example: Sports Illustrated magazine Cost Tracing Cost Allocation

7. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 6 Learning Objective 3 Explain variable costs and fixed costs.

8. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 7 Cost Behavior Patterns Example – Variable Costs 1,000 units × $52 = $52,000 What is the total handlebar cost when 3,500 bicycles are assembled? 3,500 units × $52 = $182,000 Bicycles limited buys a handlebar at $52 for each of its bicycles. What is the total handlebar cost when 1,000 bicycles are assembled?

9. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 8 Cost Behavior Patterns Example – Variable Costs As we can see, the total cost varies in proportion to changes in the related level of activity. The cost of the handlebars is therefore a variable cost However, note, the variable cost of handlebars per bicycle remains constant

10. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 9 Cost Behavior Patterns Example – Fixed Costs Bicycles by the Sea incurred $94,500 in a given year for the leasing of its plant. This is an example of fixed costs with respect to the number of bicycles assembled.

11. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 10 Cost Behavior Patterns Example – Fixed Costs What is the leasing (fixed) cost per bicycle when Bicycles assembles 1,000 bicycles? $94,500 ÷ 1,000 = $94.50 What is the leasing (fixed) cost per bicycle when Bicycles assembles 3,500 bicycles? $94,500 ÷ 3,500 = $27 However, note the fixed cost per bicycle decreases as the level of activity increases.

12. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 11 Cost Drivers The cost driver of variable costs is the level of activity or volume whose change causes the (variable) costs to change proportionately. The number of bicycles assembled is a cost driver of the cost of handlebars.

13. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 12 Relevant Range Example Assume that fixed (leasing) costs are $94,500 for a year and that they remain the same for a certain volume range (1,000 to 5,000 bicycles). 1,000 to 5,000 bicycles is the relevant range. Note – the relevant range concept could also apply to variable cost per unit when one factors in “discounts”

14. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 13 Relevant Range Example $94,500

15. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 14 Relationships of Types of Costs Direct Indirect VariableFixed

16. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 15 Learning Objective 4 Interpret unit costs cautiously.

17. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 16 Total Costs and Unit Costs Example What is the unit cost (leasing and handlebars) when Bicycles assembles 1,000 bicycles? Total fixed cost $94,500 + Total variable cost $52,000 = $146,500 $146,500 ÷ 1,000 = $146.50

18. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 17 Total Costs and Unit Costs Example $94,500 $94,500 + $52x $146,500

19. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 18 Use Unit Costs Cautiously Assume that Bicycles management uses a unit cost of $146.50 (leasing and wheels). Management is budgeting costs for different levels of production. What is their budgeted cost for an estimated production of 600 bicycles? 600 × $146.50 = $87,900 => NO !

20. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 19 Use Unit Costs Cautiously What should the budgeted cost be for an estimated production of 600 bicycles? Total fixed cost$ 94,500 Total variable cost ($52 × 600) 31,200 Total$125,700 $125,700 ÷ 600 = $209.50 Using a cost of $146.50 per unit would underestimate actual total costs if output is below 1,000 units.

21. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 20 Use Unit Costs Cautiously What should the budgeted cost be for an estimated production of 3,500 bicycles? Total fixed cost$ 94,500 Total variable cost (52 × 3,500) 182,000 Total$276,500 $276,500 ÷ 3,500 = $79.00 What is their budgeted cost for an estimated production of 3,500 bicycles? 3,500 × $146.50 = $512,750 => NO !

22. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 21 Learning Objective 5 Distinguish among manufacturing companies, merchandising companies, and service-sector companies.

23. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 22 Manufacturing Manufacturing companies purchase materials and components and convert them into finished goods. Manufacturing companies purchase materials and components and convert them into finished goods. A manufacturing company must also develop, design, market, and distribute its products. A manufacturing company must also develop, design, market, and distribute its products.

24. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 23 Merchandising Merchandising companies purchase and then sell tangible products without changing their basic form. Merchandising companies purchase and then sell tangible products without changing their basic form.

25. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 24 Service Service companies provide services or intangible products to their customers. Service companies provide services or intangible products to their customers. Labor is the most significant cost category.

26. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 25 Learning Objective 7 Describe the three categories of inventories commonly found in manufacturing companies.

27. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 26 Types of Inventory Manufacturing-sector companies typically have one or more of the following three types of inventories: 1. Direct materials inventory 2. Work in process inventory (work in progress) 3. Finished goods inventory

28. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 27 Types of Inventory Merchandising-sector companies hold only one type of inventory – the product in its original purchased form. Service-sector companies do not hold inventories of tangible products.

29. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 28 Classification of Manufacturing Costs Direct materials costs Direct manufacturing labor costs Indirect manufacturing costs* * a.k.a. manufacturing overhead costs or factory overhead costs

30. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 29 Learning Objective 6 Differentiate between inventoriable costs and period costs.

31. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 30 Inventoriable Costs Inventoriable costs (assets)… become cost of goods sold… after a sale takes place.

32. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 31 Period Costs Period costs are all costs in the income statement other than cost of goods sold. Period costs are recorded as expenses of the accounting period in which they are incurred.

33. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 32 Manufacturing Company Materials Inventory Finished Goods Inventory Revenues Cost of Goods Sold INCOME STATEMENT Period Costs Inventoriable Costs BALANCE SHEET Equals Operating Income when sales occur deduct Equals Gross Margin deduct Work in Process Inventory

34. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 33 Flow of Costs Example Bicycles Limited had $50,000 of direct materials inventory at the beginning of the period. Purchases during the period amounted to $180,000 and ending inventory was $30,000. How much direct materials were used? $50,000 + $180,000 – $30,000 = $200,000

35. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 34 Flow of Costs Example Direct labor costs incurred were $105,500. Indirect manufacturing costs were $194,500. What are the total manufacturing costs incurred? Direct materials used$200,000 Direct labor 105,500 Indirect manufacturing costs 194,500 Total manufacturing costs$500,000

36. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 35 Flow of Costs Example Assume that the work in process inventory at the beginning of the period was $30,000, and $35,000 at the end of the period. What is the cost of goods manufactured? Beginning work in process$ 30,000 Total manufacturing costs 500,000 Ending work in process 35,000 Cost of goods manufactured$495,000

37. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 36 Flow of Costs Example Assume that the finished goods inventory at the beginning of the period was $10,000, and $15,000 at the end of the period. What is the cost of goods sold? Beginning finished goods$ 10,000 Cost of goods manufactured 495,000 Ending finished goods 15,000 Cost of goods sold$490,000

44. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 43 Measuring Costs Requires Judgment Manufacturing labor-cost classifications vary among companies. The following distinctions are generally found: Direct manufacturing labor Manufacturing overhead

45. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 44 Measuring Costs Requires Judgment Manufacturing overhead Indirect laborManagers’ salariesPayroll fringe costs Forklift truck operators (internal handling of materials) JanitorsRework labor Overtime premiumIdle time

46. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 45 Measuring Costs Requires Judgment Overtime premium is usually considered part of overhead. Assume that a worker gets $18/hour for straight time and gets time and one-half for overtime.

47. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 46 Measuring Costs Requires Judgment How much is the overtime premium? $18 × 50% = $9 per overtime hour If this worker works 44 hours on a given week, how much are his gross earnings? Direct labor44 hours × $18 = $792 Overtime premium 4 hours × $ 9 = 36 Total gross earnings $828

48. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 47 Learning Objective 8 Explain why product costs are computed in different ways for different purposes.

49. ©2003 Prentice Hall Business Publishing, Cost Accounting 11/e, Horngren/Datar/Foster 2 - 48 Many Meanings of Product Cost A product cost is the sum of the costs assigned to a product for a specific purpose. 1.
