Cost Audit; It is an audit process for verifying the cost of manufacture or production of any object, on the basis of accounts as regards consumption of material or labour or other items of costs, maintained by the company. It stands for the verification of cost accounts and checks on the adherence to cost accounting plan. Cost Audit ascertains the accuracy of cost accounting records to ensure that they are in conformity with Cost Accounting principles, plans, procedures, and objective. We can say that the term cost audit means a systematic and accurate verification of the cost accounts and records and checking of observance to the objectives of the cost accounting.


As per ICWA London’ “It is the verification of the correctness of cost accounts and of the adherence to the cost accounting plan.”

The ICWAI defines cost audit as “system of audit introduced by the government of India for the review, examination, and appraisal of the cost accounting records and attendant information required to be maintained by specified industries”

From the above-cited definition of cost audit, it is clear that it is a systematic examination of cost accounts to verify the correctness of cost accounting records.

As per the Section 233 B of Company Law 1956, there is the provision for cost audit. Under this section, it is compulsory for all the public and govt. companies which are associated with the processing and production. If their aggregate value of net worth exceeds 5 crores or total sale exceeds 20 crores, the cost audit is must.
