Meaning and scope of cost accounting

Cost accounting is the process of determining and accumulating the cost of product or activity. It is a process of accounting for the incurrence and the control of cost. It also covers classification, analysis, and interpretation of cost. In other words, it is a system of accounting, which provides the information about the ascertainment, and control of costs of products, or services. It measures the operating efficiency of the enterprise. It is an internal aspect of the organization. Cost Accounting is accounting for cost aimed at providing cost data, statement and reports for the purpose of managerial decision making. The Institute of Cost and Management Accounting, London defines “Cost accounting is the process of accounting from the point at which expenditure is incurred or committed to the establishment of its ultimate relationship with cost centres and cost units.

In the widest usage, it embraces the preparation of statistical data, application of cost control methods and the ascertainment of profitability of activities carried out or planned”.  Costing includes “the techniques and processes of ascertaining costs.” The ‘Technique’ refers to principles which are applied for ascertaining costs of products, jobs, processes and services. The `process’ refers to day to day routine of determining costs within the method of costing adopted by a business enterprise.  Costing involves “the classifying, recording and appropriate allocation of expenditure for the determination of costs of products or services; the relation of these costs to sales value; and the ascertainment of profitability”.  The terms ‘costing’ and ‘cost accounting’ are many times used interchangeably. However, the scope of cost accounting is broader than that of costing. Following functional activities are included in the scope of cost accounting:

1. Cost book-keeping: It involves maintaining complete record of all costs incurred from their incurrence to their charge to departments, products and services. Such recording is preferably done on the basis of double entry system.

2. Cost system: Systems and procedures are devised for proper accounting for costs.

3. Cost ascertainment:  Ascertaining cost of products, processes, jobs, services, etc., is the important function of cost accounting. Cost ascertainment becomes the basis of managerial decision making such as pricing, planning and control.

4. Cost Analysis: It involves the process of finding out the causal factors of actual costs varying from the budgeted costs and fixation of responsibility for cost increases.

5. Cost comparisons: Cost accounting also includes comparisons between cost from alternative courses of action such as use of technology for production, cost of making different products and activities, and cost of same product/ service over a period of time.

6. Cost Control: Cost accounting is the utilization of cost information for exercising control. It involves a detailed examination of each cost in the light of benefit derived from the incurrence of the cost. Thus, we can state that cost is analyzed to know whether the current level of costs is satisfactory in the light of standards set in advance.

7. Cost Reports:  Presentation of cost is the ultimate function of cost accounting. These reports are primarily for use by the management at different levels. Cost Reports form the basis for planning and control, performance appraisal and managerial decision making.
