Accounting Information Systems 3
The Need for Cost Accounting Cost accounting provides the detailed cost data that management needs to control current operations and plan for the future. Companies must control costs in order to keep mantener prices competitive. In today s s global environment, cost information is more crucial than ever in remaining competitive. 4
Accounting Information Systems The cost management information system is an accounting information subsystem that is primarily concerned with producing outputs for internal users using inputs and processes needed to satisfy management objectives. 5
Accounting Information Systems The cost management information system has three broad objectives that provide information for-- 1) Costing out services, products, and other objects of interest to management 2) Planning and control 3) Decision making 6

Economics Cost Terms Short run Long run Fixed Variable Total Average Marginal 11
Cost Functions Short run cost function - use for day-to to-day operating decisions at least one input is fixed Long run cost function - use for strategic planning all inputs can be varied 12
Fixed Costs Do not vary with output Relevant only in the short run Examples Contrato de arrendamiento lease contract employees fixed insurance costs 13
Variable Costs Vary with output Relevant in the short and long runs Examples wages material costs social insurance taxes 14
Total Cost TC = TFC+ TVC 15
Marginal Costs and Average Costs The extra cost incurred to produce one additional unit. The total cost to produce a quantity divided by the quantity produced. Marginal and average costs are largely a function of cost behavior -- variable and fixed costs. 16
Average Fixed Costs Cost ($ s) AFC = TFC Q AFC Quantity 17

Other Cost Terms Opportunity Cost - foregone value abandonado associated with next-best use. Consider what a firm forgoes by accepting a special order. 23
Cost Terms Explicit measured by cash costs Implicit - non-cash costs measured by opportunity cost concept 24
Accounting cost 25
Basic Cost Concepts Cost is the cash or cash equivalent value sacrificed for goods and services that are expected to bring a current or future benefit genere to the organization. Costs are incurred to produce future benefits. Expired costs are called expenses. Unexpired costs are classified as assets and appear financieros on the balance sheet. Assigning cost accurately to cost objects is crucial. 26
Basic Cost Concepts A cost object is any item, such as products, customers, departments, projects, activities, and so on, for which costs are measured and assigned. Example: A bicycle is a cost object when you are determining the cost to produce a bicycle. An activity is a basic unit of work performed within an organization. Dentro de Example: Moving materials, maintaining equipment, designing products, etc. 27
Cost and Cost Terminology Cost is a resource sacrificed or forgone to achieve abandonado 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. deseado 28

Cost Classifications by Behavior 35
Cost Classifications by Behavior Cost Behavior How a cost will react to changes in in the level of business activity. Total variable costs change when the level of activity changes. Total fixed costs remain unchanged when the level of activity changes. 36
Total Variable Cost A variable cost is one that changes in total in proportion to changes in the volume of activity. Total Long Distance Telephone Bill Your total long distance telephone bill is based on how many minutes you talk. Minutes Talked 37
Variable Cost Per Unit On a per unit basis, a variable cost remains constant over a wide range of activity. The cost per long distance minute talked is constant. For example, 10 cents per minute. Per Minute Telephone Charge Minutes Talked 38
Total Fixed Cost A fixed cost is one that remains constant in total even when the volume of activity changes. Your monthly basic telephone bill probably does not change when you make more local calls. Monthly Basic Telephone Bill Number of Local Calls 39
Fixed Cost Per Unit On a per unit basis, a fixed cost changes as the volume of activity changes. The average cost per local call decreases as more local calls are made. Monthly Basic Telephone Bill per Local Call Number of Local Calls 40

Cost Behavior Patterns Example Bicycles by the Sea buys a handlebar at $52 for each of its bicycles. manubrio What is the total handlebar cost when 1,000 bicycles are assembled? 43
Cost Behavior Patterns Example 1,000 units $52 = $52,000 What is the total handlebar cost when 3,500 bicycles are assembled? 3,500 units $52 = $182,000 44
Cost Behavior Patterns Example 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. 45
Cost Behavior Patterns Example 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 46
Cost Drivers De gestión 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. 47
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. 48
Relevant Range Example Fixed Costs 120000 100000 80000 60000 40000 20000 0 $94,500 0 1000 2000 3000 4000 5000 6000 Volume 49
Classification of Costs by Traceability origen 50
Basic Cost Concepts Traceability is the ability to assign a cost to a cost object in an economically feasible way by means of a causal relationship. Direct costs are those costs that can be easily and accurately traced to a cost object. Example: The salary of a supervisor of a department, where the department is defined as the cost object. 51
Basic Cost Concepts Indirect costs are those costs that cannot be traced easily and accurately to a cost object. Example: The cost of heating and cooling a plant that manufactures five products. 52
Classification of Costs by Traceability Direct costs Costs that can be easily and conveniently traced to a unit of product or department or other cost objective. Example: Direct material Direct labor Cost of paint in the paint department of an automobile assembly plant. Indirect costs Costs that must be allocated in order to be assigned to a unit of product or department. Example: Manufacturing overhead Cost of national advertising for an airline is indirect to a particular flight. gastos 53
Direct and Indirect Costs Direct Costs Example: Paper on which Sports Illustrated magazine is printed COST OBJECT Example: Sports Illustrated magazine Indirect Costs Example: Lease cost for Time-Warner building housing the senior editors of its magazine 54
Direct and Indirect Costs Example Direct Costs: Maintenance Department $40,000 Personnel Department $20,600 Assembly Department $75,000 Finishing Department $55,000 Assume that Maintenance Department costs are allocated equally among the production departments. How much is allocated to each department? 55
Direct and Indirect Costs Example Maintenance $40,000 Assembly Direct Costs $75,000 $20,000 Allocated Finishing Direct Costs $55,000 $20,000 56
Relationships of Types of Costs Direct Variable Fixed Indirect 57
Interpret unit costs cautiously. 58
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 59
Total Costs and Unit Costs Example Total Costs 200000 150000 100000 50000 $146,500 $94,500 + $52x $94,500 0 0 500 1000 1500 Volume 60
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 61
Use Unit Costs Cautiously What is their budgeted cost for an estimated production of 3,500 bicycles? 3,500 $146.50 = $512,750 What should the budgeted cost be for an estimated production of 600 bicycles? 62
Use Unit Costs Cautiously 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. 63
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 64
Distinguish among manufacturing companies, merchandising companies, and service-sector sector companies. 65
Manufacturing Manufacturing companies purchase materials and components and convert them into finished goods. A manufacturing company must also develop, design, market, and distribute its products. 66
Merchandising Merchandising companies purchase and then sell tangible products without changing their basic form. 67
Service Service companies provide services or intangible products to their customers. Labor is the most significant cost category. Labor is the most significant cost category. 68

Manufacturing Costs Direct materials are those materials that are directly traceable to the goods or services being produced. Example: The cost of wood in furniture. Direct labor is the labor that is directly traceable to the goods or services being produced. Example: Wages of assembly-line line workers. Overhead are all other manufacturing costs. Example: Plant depreciation, utilities, property taxes, indirect materials, indirect labor, etc. 83
Nonproduction Costs Marketing (selling) costs are the costs necessary to market, distribute, and service a product or service. Example: Advertising, storage costs, and freight out. Administrative costs are the costs associated with research, development, and general administration of the organization that cannot reasonably be assigned to either marketing or production. Example: Legal fees, salary of the chief executive officer. 84
Nonproduction Costs For external financial reporting, marketing and administrative costs are not inventoried. They are referred to to as as period costs. 85

Describe the three categories of inventories commonly found in manufacturing companies. 87
Inventoriable Costs Inventoriable costs (assets) Los recursos become cost of goods sold after a sale takes place. 88
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. 89
