BCom 3rd Year Cost Audit Notes Study Material

With the growth and development of cost accounting systems, it became necessary to maintain cost records and cost books to record costs and related transactions correctly. It is necessary that either in financial accounting or in cost accounting or in the management accounting system, wherever books and records are kept, they must be examined independently to ensure that they have been kept and recorded fairly and correctly and that there are no errors of omission and commission and there is no defalcation. So once the cost accounts are prepared, they should be audited in all fairness. (BCom 3rd Year Cost Audit Notes Study Material)


Cost audit means an audit of cost accounts, which is related to deep checking and verification of the accuracy of cost techniques, methods, and accounts. Some of its definitions are as follows:

(1) “Cost audit is the verification of cost accounts and checks on the adherence to the cost accounting plan.” -I.C.M.A., London

(2) “Cost audit means the detailed checking of the costing system, technique, and accounts to verify their correctness and to ensure adherence to the objective of cost accounting.” -Smith & Day

(3) “Cost audit can be defined as verification of the correctness of cost accounts and adherence to the cost accounting principles, plans, and procedures.” I.C.W.A., India

Like a financial audit, a cost audit is also an attest function. It is a systematic and accurate recording of detailed transactions and operations of manufacturing processing, contracting, extracting, transporting, supplying, etc., so as to show the actual cost of each individual piece of work, service or process, or operation. (BCom 3rd Year Cost Audit Notes Study Material)

The cost auditor is expected to examine the cost books, cost accounts, cost statements, and all other relevant documents to see not only that they have been correctly written and recorded but that they also give a fair and correct picture of the business with regard to costing operations.

From the definitions of cost audit, it is evident that cost audit aims at:

(a) verifying that the cost books, cost accounts, and cost records have been correctly maintained as per the costing system adopted;

(b) verifying that the cost plan i.e., the prescribed routine and procedure, has been adhered to; and

(c) detecting errors and preventing fraud, misappropriations, and defalcations.


Financial accounting and cost accounting are the two main branches of the accounting system. The same criteria and principles of audit hold good in both systems of accounting and sometimes it becomes difficult to make a clear-cut distinction between the two audits.

However, an auditor of financial accounting is more concerned with financial aspects, recording of cash and bank transactions, capital, debtors, creditors, assets & liabilities, etc, while the cost auditor is more concerned with correct recording, ascertainment, presentation, and control of costs. This leads to the following points of distinction:

  1. Presentation of Report: In a financial audit, the audit report is addressed and placed before the shareholders of the company, but the cost audit report is addressed to the appointing authority. In a financial audit, the auditor is the representative of the shareholders while in a cost audit, he is the nominee of the appointing authorities and reports to them on cost-effectiveness.

In a statutory cost audit, the report is to be submitted by the cost auditor to the Central Government, with a copy to the company.

  1. Statutory Compulsion: Audit of Financial accounts has been made statutorily compulsory by the companies Act while cost audit is not compulsory except in certain cases i.e., in case of companies that carry on manufacturing or mining business and which are required to maintain Cost Accounts under Section 209(1)(d) of the Companies Act and are asked to get their accounts audited under section 233(B) by the Central Government. (BCom 3rd Year Cost Audit Notes Study Material)
  2. Details in the Annexures: The audit examination of financial accounts is not as detailed as that of cost accounts. In the case of a statutory cost audit, the cost auditor has to furnish details in the annexures along with Cost Audit Report.
  3. The focus of Audit: In a financial audit, the auditor is required to report on the Profit & Loss A/c and the Balance Sheet whether they exhibit a true and fair view of the state of affairs of the company. In the cost audit, the auditor has to report whether the company’s cost accounting records have been properly kept as to give a true and fair view of the cost of production, processing, manufacturing or mining activities, and the marketing of the product under reference. (BCom 3rd Year Cost Audit Notes Study Material)
  4. The focus of Examination: The financial auditor is required to examine that the business transactions have been recorded correctly but the cost auditor has also to see that inventory management and control, inventory limits, E.0.9. etc., have been properly adhered to.
  5. Relation with Decision-making: The financial audit is not so much related to decision-making aspects as the cost audit is related. The cost auditor points out errors and irregularities in managerial decision-making.
  6. Stock Valuation: The financial auditor has to verify the correct valuation of the closing stocks but the cost auditor has also to see that there is sufficient closing stock to meet the needs of the manufacturer. (BCom 3rd Year Cost Audit Notes Study Material)
  7. Correct Profit us. Potential Profit: The financial audit exhibits whether correct profits have been arrived at or not but in cost audit, the possibility of earning more profits is explored and advice is made available for the future for better results on the basis of previous records and experiences. (BCom 3rd Year Cost Audit Notes Study Material)
  8. An instance of Audit: Financial audit is conducted at the instance of owners of the business but a cost audit can also be done at the instances of Government, Banks and Investors, Industrial Tribunals and Customers, etc.
  9. Aspects of Audit: Financial audit is concerned with the financial aspects but an audit is more related to cost aspects. The cost auditor has to examine carrying an -carrying costs, engineering and works studies, variances, budgetary control and ratio studies, etc.

There are two main aspects of cost audit-(1) Propriety Audit and (2) Efficiency Audit.

  1. Propriety Audit: It has been defined as an “audit of executive action and plans to bear on the finance and expenditure of the company”. (Management Accounting, Feb. 1965)

This audit is related to the propriety, i.e., fitness or rightness of the expenditure made. An expenditure may have been sanctioned and it may have been supported by the vouchers, yet the propriety audit has to satisfy whether or not the expenditure made was appropriate to the circumstances of the case and that there could not have been a better alternative. So this audit is concerned with the audit of such actions of the executives as having a bearing on the finances and expenditures of the company or concern.

The cost auditor, under propriety audit, has to ensure that:

(a) the expenditure has been planned in a way as to give the optimum results:

(b) the planned expenditure, its size, and channels have produced the optimum results; and

(c) there is no other better alternative to the expenditure made and results obtained.

  1. Efficiency Audit: This is also known as a ‘Performance audit’ and is related to the working efficiency of the cost plan. It has to be seen whether the plan has been executed efficiently or not and for this the results obtained are to be judged. For example, the budget is a plan and the efficiency audit would determine whether the expenditure is incurred according to the budget and whether the results obtained are also in accordance with the budget. or not. The emphasis is on the point that:

(a) every unit of money invested must give the optimum or the best result, and

(b) the investment made in different types and areas is balanced and optimum.

Management Accounting’ defines Efficiency audit as the audit which ensures the application of the basic economic principle that resources will flow into the most remunerative channels. (BCom 3rd Year Cost Audit Notes Study Material)

The Efficiency audit is based on determining the working efficiency of the enterprise and so it is related to the examination of aspects like inventory control, productivity, utilization of installed capacity, cost control, profitability, etc.


The following are the types of cost audits:

  1. Cost Audit on behalf of Management: An audit may be instituted by the management for its own satisfaction. The purpose of this audit is to provide correct and reliable cost information to management for taking managerial decisions and to ensure that the costing department is functioning according to the plan. (BCom 3rd Year Cost Audit Notes Study Material)

The Cost Auditor is appointed by the management for this audit.

  1. Statutory Audit: Under Section 148(1) of the Companies Act, 2013, it has been laid down that where in the opinion of the Central Government it is necessary so to do in relation to any company required to include in its books of account particulars referred to therein, the Central Government may, by order, direct that an audit of cost accounts of the company shall be conducted in such manner as may be specified in the order, by an auditor who shall be a cost accountant within the meaning of the Cost and Works Accountants Act, 1956.
  2. Cost Audit by the Government: Besides the Statutory audit, the audit can be instituted by any Government-Central of State–for the following purposes:

(a) to ascertain the cost of production and marketing in case of industries to whom financial assistance in the form of subsidy, grant-in-aid, lower or free rates of taxes, etc., is to be provided,

(b) to ascertain costs in order to fix maximum prices of products,

(c) to ascertain the cost of contracts to be given to contractors under Cost-plus contracts, and

(d) to fix limits of loans to be advanced by financial corporations, small-scale industries, and banks to different industries, on the basis of production costs.

  1. Cost Audit by Contractees: Were it decided by the contractee with the contractor that the contractor would be paid the cost of the contract plus a fixed percentage of profit, as in the case of ‘Cost-plus’ contracts, the audit is instituted by the contractee to ascertain the correct cost of the contract. Similarly, where a contractor appoints sub-contractors on the basis of cost and profit basis, the contractor institutes a cost audit of the accounts of sub-contractors to settle payments. (BCom 3rd Year Cost Audit Notes Study Material)
  2. Cost Audit by Tribunals: To settle labor disputes on wages, bonuses, profit sharing, etc., the Tribunals may ask for a cost audit of the concerned businesses. Similarly, Income-tax Tribunals may direct cost audits for the assessment of tax based on the profits of a manufacturing concern. (BCom 3rd Year Cost Audit Notes Study Material)
  3. Cost Audit by Trade Associations: In the case of concerns of a similar nature costs are compared with each other under Uniform Costing or Inter-firm Comparison by Trade Associations. Trade Associations want to know the costs to seek concessions from the Governments in the gestation or take-off periods of certain concerns, and for that purpose, a cost audit is required.

Classification of Cost Audit

Cost Audit can be classified as (1) Internal audit and (2) External or Statutory audit.

(I) Internal Audit: Internal audit is done by the auditor who is in employment by the business, with the help of his departmental staff. The objectives and scope of internal audit differ from concern to concern depending on the requirements of the management.

  1. to ensure that the business is being run according to plan;
  2. to verify the correctness of accounts by vouching:
  3. to check that the budgets have been prepared correctly:
  4. to detect errors of omission, commission, and errors of principle, and to prevent frauds and defalcations;
  5. to check that forms and documents are executed regularly and submitted punctually:
  6. to ensure that accounting is done daily, as per schedule;
  7. to check whether the routine and procedures are being followed as per the Cost plan;
  8. to detect weaknesses in the system and remove them:
  9. to see that there is no communication gap between top management and the executives; the business policy and instructions are communicated to the workers as scheduled and the managerial reports are submitted in time to the management;
  10. to verify the inventory control and physically check the stocks:
  11. to compare the costs of products from period to period, analyze the causes of variations and suggest ways and means to reduce and control costs; and
  12. to effect moral checks and improve efficiency.

(II) External or Statutory Audit: The external audit is conducted with a particular object in view, by the outside auditors, and thus, has a limited scope. It may be conducted by the Tribunal, Government, Contractee, or Trade Association, but in each case, the object is specific and limited. The external auditor is not an employee of the company but an outside party and he is responsible not to the company but to his appointing authority to whom he submits his report. (BCom 3rd Year Cost Audit Notes Study Material)

It may be mentioned that statutory cost audit was introduced with the objectives (a) to make management cost-conscious, and (b) to help in improving industrial efficiency all around and to maximize production. However, such an audit may be required under the following conditions also:

  1. For fixation of retention price in case of materials of national importance such as steel, cement, etc.
  2. To check excessive profiteering.
  3. To find the reasons for cost variation from unit to unit in the same industry.
  4. For settling trade disputes about claims for higher wages, bonuses, etc.
  5. To determine the correct cost of production, where duty or tax is levied on products based on the cost of production.
  6. To find out the correct position of inefficient and uneconomic industrial units.


In order to reap the benefit of cost audit, it is necessary that it should be done in its entirety and should be done continuously. Before the commencement of the audit, the costing method and technique adopted should be examined. The list of various sheets, documents, schedules, statements, etc., related to cost and cost records and books should be obtained.

It should be examined whether the work of internal control is effectively being done. It should also be seen what is the object for conducting the audit, the scope of the audit, nature, and size of the business. In case the size of the business is very large, then the function of book-keeping and accounting and internal control system should be very effectively organized.

After examining the above aspects, the cost auditor makes his cost audit programme which is similar to that of a financial audit. The work of vouching, checking, and ticking is also similar to a financial audit.

Generally, the technique of cost audit should be as follows:

(1) All the receipts and payments should be vouched i.e., each transaction should have a voucher, so as to verify the reliability of transactions.

(2) All the calculations and postings should be verified. For this special tick mark should be adopted. If the work is more and time is less then a test check should be applied. (BCom 3rd Year Cost Audit Notes Study Material)

(3) The items of the suspense account should be examined very carefully. All the adjustment entries should be well examined.

(4) The comparison of actual data with budgeted data should be made and any variance should be carefully analyzed.

(5) As regards to the technique the following points are to be considered:

(i) Physical Examination, (ii) Physical Count, (iii) Confirmation, (iv) Examination of original document, (v) Scanning, (vi) Enquiry.

It is essential that before the audit is started, all the books of accounts and records should be posted up-to-date and vouchers filed serially. All relevant documents and information should be made available to the auditor and full cooperation be extended to him by the staff. (BCom 3rd Year Cost Audit Notes Study Material)
