What is Cost Audit?

Cost Audit means the checking and verification of the cost accountancy books, records, statements, reports and other data related to the cost of a product or service being provided by a business unit. Such verification is done by a cost accountant who is appointed by company management, with a prior approval from the Central Government, as the cost auditor.

Such verfication is done not only for the entries made in the cost accounting books but to see that the various resources are used by the company with maximum efficiency and the cost of production and cost of sales is kept to the minimum.

Cost audit is not a postmortem examination like financial audit. Cost auditor verifies the correctness of costs and if there is any inefficiency due to which additional costs have been incurred in the process of production, the cost auditor in his observations draws attention to such inefficiency and suggests measures to be used for eliminating such inefficiency.

While doing cost audit, the auditor also checks whether the cost accounting books and records have been prepared by following the accepted cost accounting principles and costing system adopted by the business unit. Cost audit, thus is the verification of correctness of cost accounts and of the adherence to the cost accounting plan.

Social Objectives of Cost Audit

Cost audit provides a lot of valuable information which can be used by the Government and social institutions to see whether the work of providing goods and services is carried out by the business organisations at proper cost and in an efficient and effective way.

Such information can be used by the Government to fix prices of certain goods and services and to take decisions about amount of subsidy to be provided to the companies engaged in producing and selling some goods and services so that the entire burden of the cost incurred by them does not fall upon the consumers of these goods and services.

Social objectives can be stated as under:

Consumer protection

Consumers are required to face the problem of inflation. The prices of the goods and services are constantly increasing and the consumers find it difficult to maintain their standard of living due to inflation. Companies engaged in producing the goods say that they are complelled to increase the prices of products because of increase in the cost of the resources used by them in production process.

However many times the increase in the cost of production is not matched by the increase made in the selling prices of the goods and services.

Increasing productivity

Cost audit provides valuable information about installed capacity of production and the actual capacity used by the industry and the companies. It thus brings to notice the idle and wasted production capacity in the company individually and in the industry collectively.

Such unused capacity can be put to use and increase in the volume of production can be achieved. This results in increasing productivity.

Decisions about Subsidy

It is the objective of cost audit to verify that cost of production is correctly ascertained on the basis of the costs recorded in the cost accountancy books, records, statements, etc. By using this information the Government can take proper decisions about the extent to which subsidy should be granted to those companies whose goods are to be sold at the prices fixed by the government.

Subsidy to be provided to the companies which export their product can be properly decided so that these companies can export their products at reduced prices and face the competition in the international markerts successfully.

Prevention of tax evasion

Government levies taxes like excise, sales tax, corporate tax, export and import duty, etc. for obtaining funds needed by it and uses such funds for various projects, schemes undertaken by it for development and welfare of the society.

Due to cost audit the Government obtains information about the quantity produced, quantity and value of sales effected by the company and payment of various taxes by the company. If any company tries to evade tax payment, it is brought to the notice of the Government and its tax department through the cost audit report.

Creation of new employment opportunities

Cost audit draws attention to unutilised and wasted resources by the company. It also guides the management of the company how these unutilised and wasted resources can be put to proper use.

Increase in volume of production also provides additional amount of profit to the company and funds created out of increased profits provide new investment opportunities to the company. Projects started by using these investment opportunities provide new jobs to the people and the severity of the unemployment problem can be reduced to some extent.

Use of alternative and better methods

Cost auditor studies the methods and techniques used by the company when he is doing the cost audit of the company. In the cost audit report he can suggest some alternative methods of doing the work.

These alternative methods and techniques can help the company to do the work at a lower cost, in a shorter time and produce better quality products. The company and the society can enjoy the benefits available from the use of the alternative and better methods suggested by the cost auditor.
