Cost Acct: Ch 2 intro to cost

Chapter 2: An Introduction to Cost Terms and Purposes

Learning Objectives

  • Cost Object: Define and illustrate what constitutes a cost object.

  • Direct vs. Indirect Costs: Distinguish between these two types of costs.

  • Variable vs. Fixed Costs: Explain the differences and behavior of these costs.

  • Unit Costs: Caution regarding the interpretation of unit costs.

  • Financial Accounting Concepts: Distinguish inventoriable costs from period costs.

  • Cost Flow: Illustrate the flow of costs in financial accounting.

  • Product Cost Computation: Explain why different computations exist for varying purposes.

  • Cost Accounting Framework: Describe a framework for effective cost accounting and management.

Basic Cost Terminology

  • Cost: Refers to a resource that has been sacrificed or forgone to achieve a specific objective.

  • Actual Cost: The cost that has already occurred.

  • Budgeted Cost: The cost predicted for future operations.

  • Cost Object: Anything for which measuring costs is desired, such as a product or project.

Cost Object Examples at Tesla

  • Product: A Tesla Model 3 vehicle.

  • Service: Telephone hotline for Tesla assistance.

  • Project: R&D for an electric truck.

  • Customer: Dubai RTA for electric taxis.

  • Activity: Setting up production machinery.

  • Department: Worker health and safety department.

Cost Accumulation and Assignment

  • Cost Accumulation: The organized collection of cost data through accounting systems.

  • Cost Assignment: Gathering costs to a cost object via tracing or allocating costs.

    • Tracing: Relates to direct, conveniently tracked costs.

    • Allocating: Applied to indirect costs in a rational manner.

Direct vs. Indirect Costs

  • Direct Costs: Easily traceable to a cost object, such as materials and labor specifically tied to production.

  • Indirect Costs: Not conveniently traceable; allocated cost via systematic methods, including utilities, rent, and administrative expenses.

Challenges in Cost Allocation

  • Examples of Direct Costs include steel, tires, and wages of assembly-line workers.

  • Examples of Indirect Costs include electricity, rent, and property taxes that support various projects or services.

Factors Affecting Cost Classifications

  • Materiality(the importance) of the cost, availability of information-gathering technology, and operational design.

  • Notably, a cost can serve as a direct cost to one object while indirect to another depending on context.

Cost Behavior Patterns: Fixed Costs and Variable Costs

  • Variable Costs: Change in total with variations in activity levels (e.g., materials used scales with production).

  • Fixed Costs: Remain unchanged in total over a specific time frame despite activity level changes.

  • Cost behavior can be analyzed per activity or time period, which is crucial in cost management.

Summary of Cost Behavior

  • Variable Costs: Change proportionally with output (e.g., additional units incur additional costs).

  • Fixed Costs: Constant in total but reduce per unit as output increases (cost per unit becomes lower with higher production).

Additional Cost Concepts

  • Mixed Costs: Contain both fixed and variable components.

  • Cost Driver: A factor that causally impacts costs based on activity levels.

  • Relevant Range: A specified range of normal activity where specific relationships between costs and activity hold true.

Understanding Cost Classification Combinations

  • Costs can be analyzed through multiple lenses:

    • Direct vs. Indirect and

    • Variable vs. Fixed

    • Important combinations include direct-variable, direct-fixed, indirect-variable, and indirect-fixed assignments.

Unit Costs Usage

  • Although usually applicable for financial reports and decision-making, a cautious approach towards unit costs is advised; total cost perspectives are often more informative.

Economic Sectors

  • Manufacturing: Firms convert materials into finished goods.

  • Merchandising: Companies sell products in their existing form.

  • Service Sector: Organizations that deliver services rather than goods.

Types of Manufacturing Inventory

  • Direct Materials: In-stock resources for production.

  • Work-in-Process (WIP): Partially completed goods still in production.

  • Finished Goods: Completed products awaiting sale.

Type of merchandising- sectors inventory

  • Only has one type: merchandise inventory

Cost Classifications in Manufacturing

  • Inventoriable Costs: These include direct materials, direct labor, and indirect manufacturing, which are critical for determining product costs.

    • Remember direct means traceable.

  • Inventoriable vs. Period Costs: Differentiation between costs that remain assets on balance sheets until the sale occurs versus those treated as current period expenses.

  • Inventoriable cost can be expensed as ‘Cost of Goods Sold’ while periodic cost are expensed through other accounts relating to income statement.

Financial Presentation of Costs

  • Cost Flows: Depiction of how costs move through production towards the income statement, emphasizing flow categories like direct materials and WIP.

Framework for Cost Accounting and Management

  • Cost accounting serves three essential functions: calculating product and service costs, gathering planning and performance evaluation data, and informing decision analysis.

Key Terms for Review

  • A selection of terms including actual cost, budgeted cost, cost driver, cost object, direct costs, fixed costs, period costs, and relevant range provides a foundational vocabulary for cost accounting discussions.
