Cost System
Keys to a good cost system:
• Oriented to the needs of the decision makers
• Designed so that benefits exceed costs

Cost Management Systems
• The objective of the cost management systemis to provide information about costs relevantfor decision making.
• The cost system accumulates and reports costsabout processes, products, and services.

Reasons to Calculate Productor Service Costs
• For decision making
• For deciding what to sell
• For setting prices
• For knowing the cost of goods sold
• For knowing the cost of inventory

Fundamental Themes Underlyingthe Design of Cost Systems
• Cost systems should have a decision focus.
• Different cost information is used fordifferent purposes.
• Cost information for managerial purposesmust meet the cost-benefit test.

Basic Cost Flow Model
• How costs and units move through inventories:

• This is true for the following accounts:– Raw Materials (RM)– Work-in-Process (WIP)– Finished Goods (FG)

Costing with No Work-in-Process Inventories
• Baxter Paint begins production on April 1.
• It starts and completes production of 100,000gallons of paint in April and has no endingwork-in-process inventory.
Materials $ 400,000Labor 100,000
Manufacturing overhead 500,000Total $1,000,000
Cost of resources used in April:

Costing with No Work-in-Process Inventories
• What are the costs at the end of the period?
• $1,000,000 was added to work-in-processand then transferred out to finished goods.
• Since Baxter produced 100,000 gallons ofpaint, then the cost per gallon of paint is $10.

Costing with Work-in-Process Inventories
• How do we cost Baxter’s 20,000 gallons of paint thatare only half finished?
• 20,000 gallons half finished is equivalent to 10,000gallons finished.
• 90,000 gallons transferred out plus 10,000 equivalent gallonsof finished paint equals 100,000 equivalent gallons of paint.
Gallons of paint transferred out 90,000Equivalent gallons of finished paint 10,000Total equivalent gallons of paint 100,000

Materials $390,000Labor 100,000
Manufacturing overhead 500,000Total $990,000
Costs incurred in May:
$990,000/100,000 gallons = $9.90 per gallon
90,000 gallons × $9.90/gallon = $891,000
