Cost
• A measurement,• In monetary terms,• Of the amount of resources used for
some purpose.
Cost Object
Product, project, organizational unit, or other activity or purpose for which costs are measured.
Can be defined broadly or narrowly. E.g., an entire production run of jeans vs.
one pair of jeans.
17-3
17-4
Full Cost
All the resources used for a cost object. Includes:
Direct production costs. Indirect production costs. Selling cost. General and administrative cost.
17-5
Direct Costs
Costs specifically traced to (caused by) the cost object.
E.g., denim cloth used in jean manufacturing.
17-6
Indirect Costs
Costs associated with (or caused by) two or more cost objects jointly.
Not possible or feasible to trace directly to a single cost object.
Terms “direct” and “indirect” are only meaningful in context of a specific cost object (i.e., can change as cost object(s) change).
Allocation of Indirect Costs
Indirect costs are allocated to departments or organizational units using the following steps:
1. Choose an allocation base for the indirect cost.
2. Compute an indirect cost allocation rate.3. Allocate the indirect cost.
Choose an Allocation Base
Cost or Expense BasisIndirect labour Time spentBuilding amortization Square metresHeat, lights, etc. Square metresJanitorial services Square metresPayroll and personnel # of employeesPurchasing # of purchase orders placed
Choose an Allocation Base• Lets consider a medical clinic which has 2 tenants,
a doctor and dentist • Rent for the year is $120,000.• Total square metres occupied by the clinic is 1200.• What is the rent per square metre?• $120,000 ÷ 1,200 = $100• The rent would be allocated to the doctor and
dentist bases on how much space they use in the clinic
Allocate the Indirect CostThe doctor occupies 900 square metres.
How much rent is allocated to the doctor?
• 900 × $100 = $90,000 How much rent is allocated to the dentist?• 1,200 – 900 = 300 square metres• 300 × $100 = $30,000
17-11
What is GAAP Cost?
Limited guidance. Any “systematic and rational” method
of cost assignment is allowed.
17-12
Elements of product cost
Cost organized into categories (i.e., materials, labor, overhead, etc.).
Collected in a product costing system. Accumulates and reports costs of product
cost objects. Cost object can be a physical product or a
service.
17-13
Direct Material Cost
Quantities of material that can be specifically identified with a cost object in an economically feasible manner.
Also know as raw materials. Usually priced at unit price of material.
17-14
Direct Labor Cost
Quantities of labor that can be specifically identified with a cost object in an economically feasible manner.
Usually priced at unit price of labor.
17-15
Overhead Costs All other production costs. Indirect production costs.
Indirect materials. Indirect labor. Utilities. Maintenance. Depreciation. Insurance. Taxes. Etc.
17-16
Other Cost Terminology
Conversion costs. All production costs needed to convert
direct material into finished goods. Direct labor cost + overhead cost.
Full production cost. Also called inventory cost, product cost. Direct materials + direct labor +
overhead.
17-17
Nonproduction Costs
Also known as period costs. Includes:
Selling costs. Marketing (order-getting) costs. Logistics (order-filling) costs.
General and administrative costs. Research and development costs. Interest costs.
17-18
Summary
• Full cost: Production costs.
Direct materials. Direct labor. Overhead.
Nonproduction costs. Selling cost. General and administrative cost. Research and development costs. Interest costs.
17-19
Product Costing Systems
• Involves accounting for the:1. Acquisition of resources needed for
production.2. Production process.3. Sale of completed products.
17-20
Production Inventory Accounts
• Materials inventory.– Increased by acquisition of materials.– Decreased when materials are used in production.
• Work in process inventory.– Collects all costs of production– Increased when material, labor, and overhead are added
to (used in) the production process.– Decreased when product is completed.
• Finished goods inventory.– Increased when product is completed.– Decreased when product is sold.
17-21
Overhead Account
Clearing account (i.e., temporary holding account). Increased (debit) by incurrence of overhead costs
(e.g., usage of indirect materials, incurrence of indirect labor costs, factory utilities cost, depreciation cost on factory assets, etc.).
Decreased (credit) when costs are applied to the product(s) being produced (i.e., placed into Work in Process Inventory).

17-23
Nonmanufacturing Companies• Merchandising companies.
• Since cost of goods sold is invoice cost, only requires simple system (relative to manufacturing company).
Service organizations. Cost object is “job” (e.g., “patient” in a
hospital, “vehicle” in a auto repair shop, “client” for an law office.
Job cost record kept for each job. Cost record serves as work in process
inventory account.
17-24
Nonprofit Organizations
• E.g., healthcare, educational, performing arts, government.
• Cost object is programs not products.• Similar cost accounting practices to profit
organizations.
17-25
Life Cycle Costing
• Cost system considers all of a product’s costs from “birth to abandonment.”– Birthing costs.
• Necessary to develop product and bring it to market.
• Includes research and development, product testing, initial market creation, salesperson training.
– Abandonment costs.• Incurred after product is discontinued and doesn’t
produce significant revenues.• Disposal of plant and equipment, severance costs,
restoring polluted land.
17-26
Uses of Full Costs
Financial reporting. Determine cost of inventory and cost of
sales. Analysis of profitability.
Entire business and parts of the business (e.g., product, product line, plant, division, sales territory, etc.).
17-27
Uses of Full Costs
Product pricing. Cost plus contracts.• Contribution pricing.
• Price set below full cost, but above variable costs.
Setting regulated prices (e.g., utilities, cable).
17-28
Uses of Full Costs
Product pricing. Normal pricing.
Recover direct costs, recover applicable indirect costs, make a satisfactory profit.
Applicable for differentiated products (i.e., has distinct characteristics.
For undifferentiated products (i.e., commodities), price set by market.
17-29
Uses of Full Costs Product pricing.
• Time and material pricing.• Price material cost and labor cost separately (i.e.,
material loading charge, billing rate).• Used by repair shops, physicians, lawyers,
consultants, etc.
• Target pricing (costing).• Price set first (based on competitive strategy).• Then product is designed to cover full cost and
profit.
17-30
Uses of Full Costs
Strategic positioning. Strategic cost management.
Use of cost management to help better understand one’s advantages and disadvantages relative to competitors.
Covers entire value chain.
