Chapter 2 Cost Concepts and the Cost Accounting Information Systems Pertemuan ke 2
Learning Objectives • Mampu mendefinisikan pengertian cost object • Mampu menjelaskan term direct cost and indirect cost • Considerate for creating a cost accounting information system • Explain about cost classification
COST CONCEPTS • Cost versus Expense • Cost object is defined as any item or activity for which costs are accumulated and measured • Traceability of Costs to Cost Object • Cost traceability in Service Industries
The Cost Information System • An integrated and coordinated information system provide information needed by managers • Designing a cost accounting information system requires an understanding of both the organizational structure and the type of information required. • Chart of Accounts • Electronic Data Processing (EDP)
Classifications of Costs • PRODUCT, as follow : • Manufacturing Costs : Direct Materials, Direct Labor and Factory Overhead ( indirect material, indirect labor and other factory costs ) • Commercial Expenses : Marketing Expenses and Administrative Expenses
Classifications of Costs • VOLUME OF PRODUCTION, as follow: • Variable Cost change in proportion to changes in activity within a relevant range. • Fixed cost are constant in total amount within a relevant range of activity • Semi Variable cost contain both fixed and variable elements
Classifications of Costs • MANUFACTURING DEPARTMENTS, as follow : • Producing Departments and Service Department • Direct Departmental Cost and Indirect Departmental Cost • Common Costs and Joint Cost
Classifications of Costs • ACCOUNTING PERIOD, as follow : • Capital Expenditure • Revenue Expenditure • DECISION, ACTION OR EVALUATION • Differential Cost • Sunk Cost
PRODUCT • Manufacturing Cost= Direct Materials + Direct Labor + Factory Overhead • Prime Cost= Direct Materials + Direct Labor • Convertion cost = Direct Labor + factory overhead
DIRECT MATERIALS: materials that form an integral part. • DIRECT LABOR: converts direct materials into finished product. • FACTORY OVERHEAD: all manufacturing costs not traced directly to specific output. • Factory Overhead= Indirect Materials + Indirect Labor + Other Indirect Cost
INDIRECT MATERIALS: needed for the completion of a product part of the product. • INDIRECT LABOR: not directly traced to the composition of finished product; e.g. wages, maintenance • Manufacturing Cost + Commercial Expenses = Total Operating Cost
COMPUTER INTEGRATED MANUFACTURING: employing database management technology on a company-wide scale. • Commercial Expense= marketing + administrative
COST IN RELATION TO THE VOLUME OF PRODUCTION • VARIABLE COST: change in proportion to changes in activity within a relevant range. • FIXED COST: constant in total amount within a relevant range of activity. • SEMIVARIABLE COST: contain both fixed and variable components.
COST IN RELATION TO MANUFACTURING DEPARTMENTS OR OTHER SEGMENTS • PRODUCING DEPARTMENTS: manual and machine operation such as forming and assembling. • SERVICE DEPARTMENT: rendered for the benefit of other departments. • COMMON COST: cost of facilities/services; employed by two or more operations. • JOINT COST: one product makes it inevitable that one or more products are produced.
COST IN RELATION TO AN ACCOUNTING PERIOD • CAPITAL EXPENDITURE: intended to benefit future periods, reported as an asset. • REVENUE EXPENDITURE: benefits the current period and is reported as an expense.
COSTS IN RELATION TO A DECISION, ACTION OR EVALUATION • DIFFERENTIAL COST: one name for a cost that is relevant to a choice among alternatives. • OUT-OF-POCKET COST: differential cost will be incurred only if one particular alternative is followed. • OPPORTUNITY COST: amount/revenue that will be missed or lost if a particular alternative is followed. • SUNK COST: irrelevant to the decision. • AVOIDABLE: relevant to the decision. • UNAVOIDABLE: may be unaffected by the decision. • BALANCED SCORECARD: tool for implementing an organization's strategy; set of important interconnected performance measures.
