What are the Advantages of Cost Audit?

Cost audit and its advantages:

We all know that audit involves verification and examination. Since books of account form the very basis for verification, it is often said that auditing begins where accounting ends. An audit is conducted to check whether the books of account present a true and fair view of the state of affairs or not.

When this concept of auditing is applied to cost records, it becomes a more specific and specialized form of audit activity. It is named cost audit. Cost audit refers to the verification of cost records/accounts and acts as a check on the adherence to cost accounting standards. It checks whether cost accounts, statements, and cost data are accurate and adhere to cost principles.

Thus, cost audit primarily comprises two things:

  • The verification of cost accounting records, such as the accuracy of cost accounts, cost reports, cost statements, cost data, and costing methods.
  • Examining such records to ensure that they correspond to the cost accounting plans, procedures, and objectives/principles.

In this blog, we have discussed the functions of cost audit, its types and advantages.

Section 148 of the Companies Act 2013 confers powers on the Central Government to direct certain classes of companies to get their cost records maintained and audited by a cost accountant. In other words, a cost audit is mandatory for certain specified classes of companies producing specified goods. Certain classes of companies involved in the manufacture of such goods or the provision of such services as may be prescribed and with a net worth or turnover of such amount as may be prescribed are directed to have their cost records audited. The cost audit report is furnished to the Central Government.

Functions of cost audit

There are mainly four functions of cost audit. These include:

  • Verification of cost records as part of the process of audit.
  • Examination of the correctness and accuracy of cost records and cost accounts.
  • Analysis of whether the prescribed procedures and principles of cost accounting have been properly followed by the entity or not.
  • Evaluation that the prescribed cost accounting procedures continue to be relevant for the entity under audit.

This includes an evaluation of (a) the appropriateness of cost accounting systems, records, and procedures, (b) their proper maintenance, (c) their proper compilation in the form of cost statements, and (d) conformity to the required cost accounting procedures.

Forms of cost audit

A cost audit is conducted in addition to a financial audit. It addresses two major aspects of a business enterprise, i.e., protective and constructive.

1. Propriety audit

From the protective aspect, a cost audit examines the following:

  • Detection of fraud and errors
  • Verification of cost records and ensuring that they are correctly maintained in accordance with the generally accepted cost accounting principles followed in the industry in which the entity operates
  • Whether the prescribed system of cost accounting is properly carried out or not

2. Efficiency audit

From the constructive aspect, a cost audit examines the following:

  • Whether the existing procedures are adequate and effective in respect of managerial decisions
  • How can optimum results be obtained through projected expenditure?
  • Is there a possibility of making a more profitable investment of money in another area?
  • What’s the rate of return on capital employed?

Advantages of cost audit

As stated earlier, a cost audit is an independent evaluation of the cost statements, cost records, and other associated information of an enterprise in order to offer an opinion on them. It helps to determine whether cost records are accurate or not and whether they adhere to the cost accounting principles or not.

Cost audit is useful for cost control, cost reduction, and the efficient use of scarce resources. Additionally, a cost audit makes sure that accurate records are kept regarding the purchases and use of materials as well as costs associated with wages, overhead, etc. It also assures that the business unit was run in a cost-effective and efficient manner.

With an effective cost audit in place, the effectiveness of operations involved in the production of goods or services is increased. It has both internal and external advantages. In fact, the importance of cost audit and its advantages can be discussed from the viewpoints of:
