Cost Accounting Cost accounting systems provide information to help managers make better decisions. Managers who use cost accounting information to make decisions need to understand the cost terms used in their organizations. Because cost accounting systems are tailored to the needs of individual companies, several terms are used in practice to describe the same or similar cost concepts, depending on the use or the audience. Therefore, before we discuss the design of cost systems to aid decision making, we introduce a set of terms that will be used throughout the course. These terms are important to the discussion because they will be the “language” we use to communicate for the remainder of the lessons.

4 Cost Concept A cost is a sacrifice of resources. Every day, we buy many different things: clothing, food, books, music, perhaps an automobile, and so on. When we buy one thing, we give up (sacrifice) the ability to use these resources (typically cash or a line of credit) to buy something else. The price of each item measures the sacrifice we must make to acquire it. Whether we pay cash or use another asset, whether we pay now or later (by using a credit card), the cost of the item acquired is represented by what we forgo as a result.

Cost versus Expenses It is important to distinguish cost from expense. An expense is a cost charged against revenue in an accounting period; hence, expenses are deducted from revenue in that accounting period. We incur costs whenever we give up (sacrifi ce) resources, regardless of whether we account for it as an asset or an expense. (We may even incur costs that the fi nancial accounting system never records as an asset or expense. An example is lost sales.) If the cost is recorded as an asset (for example, prepaid rent for an offi ce building), it becomes an expense when the asset has been consumed (i.e., the building has been used for a period of time after making the prepayment).

6 What is Cost? Cost Outlay Cost Past, present, or future cash outflow
LO1 Explain the basic concept of “cost”. Cost Outlay Cost Past, present, or future cash outflow Opportunity Costs Forgone benefit from the best alternative course of action Expense Cost charged against revenue in an accounting period

7 Cost Example Cost of the outing? Opportunity Cost Outlay Cost
Serra wants to go out with her friends for a night of fun and adventure. Cost of the outing? Opportunity Cost Outlay Cost Passing her accounting exam and a new pair of shoes! $50 to pay for dinner and drinks

8 The cost of tuition, books, and all other educational expenses
Cost Example Your education costs? Outlay Cost Opportunity Cost The interest on the money you would save by not attending college and the income you will forgo while in college The cost of tuition, books, and all other educational expenses

9 Recording Costs in Financial Statements
LO2 Explain how costs are presented in financial statements. Income Statements Service Company Merchandising Company Service Revenues - Cost of Services Sold = Gross Margin - General Selling and Administrative Costs = Operating Profit Cost incurred to purchase the goods sold Sales Revenues - Cost of Goods Sold = Gross Margin - General Selling and Administrative Costs = Operating Profit Cost of billable hours The excess of operating revenue over costs necessary to generate those revenues

10 Manufacturing Company Costs
Two types of manufacturing company costs: Product Costs: Costs relating to inventory Period Costs: Non-manufacturing costs related to the firm All Costs Product Costs: Period Costs: Costs incurred to product the product Costs incurred to sell a product and operate the business Recorded as an asset “inventory” when cost is incurred Recognized as an expense when the cost is incurred Recognized as an expense when the product is sold

11 A Manufacturing Company’s Income Statement
Sales Revenue - Cost of Goods Sold = Gross Margin - General Selling & Administrative Costs = Operating Profit Product costs recorded as “inventory” when cost is incurred Cost incurred to manufacture the product sold Expensed when sold Period costs recorded as an expense in the period the cost is incurred

12 Product vs. Period Costs
Product Costs: Costs that are recorded as an asset in inventory when incurred and expensed as Cost of Goods Sold when sold. Period Costs: Costs that are expensed under General Selling and Administrative Costs when incurred.

13 Product Costs: Direct vs. Indirect
Direct Costs: Costs that, for a reasonable cost, can be directly traced to the product. Direct Materials: Materials directly traceable to the product. Direct Labor: Work directly traceable to transforming materials into the finished product. Indirect Costs: Cost that cannot reasonably be directly traced to the product. Manufacturing Overhead: All production costs except direct materials and direct labor. Indirect Materials Indirect Labor Other Indirect Costs

14 Tracing Costs Sara decides to go out with friends to a nice dinner and a movie. Identify the object A night on the town Indirect Cost Direct Costs The cost of the dinner and the movie The cost of Sara’s dress, shoes, and car.

15 Manufacturing Costs: Product Costs
Inventory Costs Direct Materials Prime Costs: The “primary” costs of the product Direct Labor Conversion Costs: Cost necessary to “convert” materials into a product Direct Labor Manufacturing Overhead

16 Product Cost Review Given the following data → Direct cost?
Direct Materials $8.00 Direct Labor $7.00 Manufacturing Overhead $14.00 Given the following data → Direct cost? DM + DL = $15.00 Prime cost? DM + DL = $15.00 Conversion cost? DL + MOH = $21.00 Indirect Cost? MOH $14.00 Total Product Cost? DM + DL + MOH = $29.00

17 Period Costs: Non-manufacturing Cost
Recognized as an expense when the cost is incurred. Advertising Marketing: Costs necessary to sell the products. Sales Commissions Shipping Costs Executive Salaries Administrative: Costs necessary to operate the business. Data Processing Legal Costs

18 Cost Allocation LO3 Explain the process of cost allocation.
Assigning indirect cost to a cost object 1. Define the cost pool: The collection of costs to be assigned to cost objects. 2. Determine the cost allocation rule: The method used to assign costs in the cost pool to cost objects. 3. Assign the cost object: Any end to which a cost is assigned – product, product line, department, customer, etc.

19 Example: Cost Allocation Rockford Company
Situation: Rockford has two divisions, East Coast and West Coast. Both divisions are supported by the IT Department. East Coast West Coast Total Revenues $80 million $20 million $100 million 1. Define Cost Pool: IT Department’s Costs of $1,000,000 2. Determine the Cost Allocation Rule: IT costs are allocated based on divisional revenue. (% of Revenue) 3. Assign the Cost Object: East Coast: 80% of cost = $800,000 West Coast: 20% of cost = $200,000

20 Manufacturing Cost Flows
LO4 Understand how material, labor, and overhead costs are added to a product at each stage of the production process. Product costs are recorded in inventory when cost is incurred. A manufacturing company has three inventory accounts: 1. Raw Materials Inventory: Materials purchased to make a product. 2. Work-in-Process Inventory: Products currently in the production process, but not yet completed. 3. Finished Goods Inventory: Completed products that have not yet been sold.

21 Inventory Accounts – The Balance Sheet
Raw Materials Inventory Beg. RM Inventory + Purchases = Raw Materials Available for Production - Raw Materials Transferred to WIP = Ending RM Inventory Work-in-Process Inventory Beg. WIP Inventory + Direct Materials Transferred from Raw Materials + Direct Labor + Manufacturing Overhead = Total Manufacturing Costs - Cost of Good Completed & Transferred to Finished Goods = Ending WIP Inventory Finished Goods Inventory Beg. FG Inventory + Cost of Goods Completed & Transferred from WIP = Goods Available for Sale - Cost of Good Sold = Ending FG Inventory To the Income Statement

22 Jackson Gears Cost of Goods Manufactured Statement For the Year Ending December 31, 200X

23 Jackson Gears Cost of Good Sold Statement For the Year Ending December 31, 200X
Beginning Finished Goods Inventory, Jan. 1 $ 420,000 Cost of Goods Manufactured 13,610,000 Finished Goods Available for Sale 14,030,000 Less: Ending Finished Goods Inventory, Dec. 31 930,000 Cost of Goods Sold $ 13,100,000 =========

24 Jackson Gears Income Statement For the Year Ending December 31, 200X
Sales $ 20,450,000 Less: Cost of Goods Sold 13,100,000 Gross Margin 7,350,000 Less: Marketing & Administrative Expenses 3,850,000 Operating Profit $ 3,500,000 =========

25 Cost Behavior Cost Behavior?
LO5 Define basic cost behaviors including fixed, variable, semi-variable, and step costs. Cost Behavior? How costs respond to a change in activity level within the relevant range Relevant Range? Activity levels within which a given total fixed cost or unit variable cost will be unchanged

26 Fixed Costs Fixed costs remain unchanged as volume changes within the relevant range. Fixed costs per unit varies inversely to a change in activity. Fixed costs are “fixed” in “total” as activity changes. Costs ($) Activity Level

27 Sara’s Night on the Town
Fixed Costs Fixed costs are “fixed” in “total” as activity changes Fixed cost per unit varies inversely with a change in activity. Cost of a dress ($) Number of times the dress is worn

28 Variable Costs Costs that change in direct proportion with a change in the volume within the relevant range. Variable costs “vary” in “total” as activity changes. Variable cost per unit stays constant when activity changes within the relevant range. Cost ($) Activity Level

29 Sara’s Entertainment Expenses
Variable Costs Variable costs “vary” in “total” as activity changes over the relevant range. Variable cost per unit remains constant when activity changes over the relevant range. Drink Cost ($) Number of drinks

30 Semi-variable Costs Costs that have both fixed and variable components. Also known as MIXED COSTS.

31 Sara’s Entertainment Semi-variable costs
The fixed component is “fixed” in total as activity changes over the relevant range. The variable component “varies in total as activity changes over the relevant range. Cost ($) Number of movies

32 Step Costs Costs that increase in total with steps when the volume changes to a particular level. Step costs are also known as semi-fixed costs. Example: If a factory can produce 100,000 units a month and the firm needs to produce 120,000 units then more factory space must be procured. The additional space will only be purchased if 100,000 units are exceeded. Costs ($) Cost of 2nd rented space Cost of 1st rented space Cost of original factory Activity Level

33 Product Cost Components
LO6 Identify the components of a product’s costs. Full Cost: The sum of all costs of manufacturing and selling a unit of the product. (GAAP) Full Absorption Cost: The sum of all variable and fixed costs of manufacturing a unit of the product. Variable Cost: The sum of all variable costs of manufacturing and selling a unit of the product.

34 DM + DL + VMOH + FMOH + VMA + FMA = $40
Costs: An Example Given the following: Direct Materials = $8 Direct Labor = $7 1. What is the full cost per unit? Variable Manufacturing Overhead = $8 Fixed Manufacturing Overhead = $6 Variable Marketing & Admin = $4 DM + DL + VMOH + FMOH + VMA + FMA = $40 Fixed Marketing & Admin = $7 3. What is the variable cost per unit? What is the variable cost per unit? The variable cost per unit is all variable costs of manufacturing and selling a unit of product. In this example, variable costs include direct materials, direct labor, variable manufacturing overhead and variable marketing and administrative costs. The variable cost for unit in this example is $27. 2. What is the full absorption cost per unit? DM + DL + VMOH + VMA = $27 DM + DL + VMOH + FMOH = $29

35 Making Costs Information Useful
LO7 Understand the distinction between financial and contribution margin income statements. Full Absorption Costing: Variable Costing Required by GAAP Used for: Financial purposes External reporting Used for: Managerial purposes Internal decision-making Sales Revenue - Cost of Goods Sold = Gross Margin Sales Revenue - Variable Costs = Contribution Margin

36 Making Cost Information Useful, Continued…
Contribution Margin Income Statement Financial Income Statement Full Absorption Costing Variable Costing Sales Price - Full Absorption Cost = Gross Margin Sales Price - Variable Cost = Contribution Margin

37 Product vs. Period Full Absorption Costing Variable Costing
Variable Manufacturing Costs Product Costs Variable Manufacturing Overhead Fixed Manufacturing Costs Fixed Manufacturing Costs Variable Marketing & Admin Costs Period Costs Variable Marketing & Admin Costs Fixed Marketing & Admin Costs Fixed Marketing & Admin Costs

38 Income Statement: Full Absorption Costing
Sales Revenue Cost of Goods Sold = Gross Margin - Marketing & Admin Cost = Operating Profit Variable and Fixed Manufacturing Costs Period Costs Variable and Fixed Marketing & Admin Costs

39 Income Statement: Variable Costing
Variable Manufacturing Costs and Variable Marketing & Admin Costs Sales Revenue Variable Costs = Contribution Margin - Fixed Costs = Operating Profit Fixed Manufacturing Costs and Fixed Marketing & Admin Costs
