1 7 Contract Costing BASIC CONCEPTS AND FORMULAE Basic Concepts 1. Contract costing:- Contract or terminal costing, as it is termed, is one form of application of the principles of job costing. In fact a bigger job is referred to as a contract. Contract costing is usually adopted by building contractors engaged in the task of executing Civil Contracts. 2. Sub-Contract : Sub-contract costs are also debited to the Contract Account. 3. Extra work: The extra work amount payable by the contractee should be added to the contract price. If extra work is substantial, it is better to treat it as a separate contract. If it is not substantial, expenses incurred should be debited to the contract account as Cost of Extra work. 4. Cost of work certified: All building contractors received payments periodically known as running payment on the basis of the architect s or surveyor s certificates. But payments are not equal to the value of the work certified, a small percentage of the amount due is retained as security for any defective work which may be discovered later within the guarantee period. 5. Work uncertified: It represents the cost of the work which has been carried out by the contractor but has not been certified by the contractee s architect. It is always shown at cost price. 6. Retention money: A contractor does not receive full payment of the work certified by the surveyor. Contractee retains some amount (say 10% to 20%) to be paid, after sometime, when it is ensured that there is no fault in the work carried out by contractor. 7. Work-in-progress: In Contract Accounts, the value of the work-in-progress consists of (i) the cost of work completed, both certified and uncertified; (ii) the cost of work not yet completed; and (iii) the amount of profit taken as credit. In the Balance Sheet, the work-in-progress is usually shown under two heads, viz., certified and uncertified. 8. Notional profit : It represents the difference between the value of work certified and cost of work certified.

2 7.2 Cost Accounting 9. Estimated profit : It is the excess of the contract price over the estimated total cost of the contract. 10. Cost plus Contract : Under Cost plus Contract, the contract price is ascertained by adding a percentage of profit to the total cost of the work. Such type of contracts are entered into when it is not possible to estimate the Contract Cost with reasonable accuracy due to unstable condition of material, labour services, etc. 14. Operating Costing: It is a method of ascertaining costs of providing or operating a service. This method of costing is applied by those undertakings which provide services rather than production of commodities. 15. Multiple Costing: It refers to the method of costing followed by a business wherein a large variety of articles are produced, each differing from the other both in regard to material required and process of manufacture. In such cases, cost of each article is computed separately by using, generally, two or more methods of costing. Basic Formulas 1. When work on contract has not reasonably advanced, no profit is taken into account. In practice, no profit is calculated when work certified is less than 1/4 th but less than ½ of the contract price. 2. When work certified is more than 1/4 th but less than ½ of the contract price, following formula is used to determine the figures of profit to be credited to profit and loss account: 1/3 Notional profit Cash recieved 3. When work certified is more than ½ of the contract price, but it is still not in the final stage, following formula is used to determine the figure of profit to be credited to profit and loss account: 2/3 Notional profit Cash received 4. When the contract is almost complete, an estimate total profit is determined by deducting aggregate of cost to date and estimated additional expenditure from contract price. A portion of this estimated total profit is credited to profit and loss account. The figure to be credited to profit and loss account is ascertained by adopting any of the following formulae: 4.1 Estimated total profit Contract price

3 Contract Costing Estimated total profit Cash received Contract price 4.3 Estimated total profit Cost of Work to date Estimated total cost 4.4 Estimated total profit Cost of Work to date Estimated total cos t Cash received 5. Profits on incomplete contracts: The overriding principle being that there can be no attributable profit until the outcome of a contract can reasonably be foreseen. Of the profit which in the light of all the circumstances can be foreseen with a reasonable degree of certainty to arise on completion of the contract there should be regarded as earned to date only that part which prudently reflects the amount of work performed to date. The method used for taking up such profits needs to be consistently applied. 6. The computation of escalation claim is based on wording of escalation clause. Normally it is calculated on stipulated quantity of material and labour hours based on price and rate differential. 7. and consequent payment: and consequent payment m 7.1 The amount of work certified can be debited to contractee s account. On receipt of money from contractee, his personal account will be credited and cash or bank account, as the cause may be will be debited. 7.2 At the time of balance sheet preparation, Contractee s Account will be shown on the Assets side as debtors. 7.3 Under the second method (it is more common than the first, students are advised to follow this method only) the amount of work certified is debited to work-in-progress account and credited to contract account. The work-inprogress should be shown on the assets side after deduction of cash received. Next year work-in-progress account will be debited to contract account. Question 1 Write note on cost-plus-contracts. These contracts provide for the payment by the contractee of the actual cost of manufacture plus a stipulated profit, mutually decided between the two parties. The main features of these contracts are as follows:

4 7.4 Cost Accounting 1. The practice of cost-plus contracts is adopted in the case of those contracts where the probable cost of the contracts cannot be ascertained in advance with a reasonable accuracy. 2. These contracts are preferred when the cost of material and labour is not steady and the contract completion may take number of years. 3. The different costs to be included in the execution of the contract are mutually agreed, so that no dispute may arise in future in this respect. Under such type of contracts, contractee is allowed to check or scrutinize the concerned books, documents and accounts. 4. Such a contract offers a fair price to the contractee and also a reasonable profit to the contractor. 5. The contract price here is ascertained by adding a fixed and mutually pre-decided component of profit to the total cost of the work. Question 2 Write notes on Escalation Clause Escalation Clause: This clause is usually provided in the contracts as a safeguard against any likely changes in the price or utilization of material and labour. If during the period of execution of a contract, the prices of materials or labour rise beyond a certain limit, the contract price will be increased by an agreed amount. Inclusion of such a term in a contract deed is known as an 'escalation clause' An escalation clause usually relates to change in price of inputs, it may also be extended to increased consumption or utilization of quantities of materials, labour etc. In such a situation the contractor has to satisfy the contractee that the increased utilization is not due to his inefficiency. Question 3 Discuss briefly the principles to be followed while taking credit for profit on incomplete contracts Principles to be followed while taking credit for profit on incomplete contracts: The portion of profit to be credited to, profit and loss account should depend on the stage of completion of the contract. This stage of completion of the contract should refer to the certified work only. For this purpose, uncertified work should not be considered as for as possible. For determining the credit for profit, all the incomplete contracts should be classified into the following four categories. (i) Contract less than 25% complete (ii) Contracts is upto 25% or more but less than 50% complete

5 Contract Costing 7.5 (iii) Contracts is upto 50% or more but less than 90% complete (iv) Contracts nearing completion, say between 90% and 100% complete. The transfer of profit to the profit and loss account in each of the above cases is done as under: (i) Contract less than 25% complete: if the contract has just started or it is less than 25% complete, no profit should be taken into account. (ii) Contracts is upto 25% or more but less than 50% complete: In this case one third of the notional profit reduced in the ratio of cash received to work certified, may be transferred to the profit and loss account. The amount of profit to be transferred to the profit and loss account may be determined by using the following formula: 1 Cash received Notional profit 3 (iii) Contracts is upto 50% or more but less than 90% complete: In this case, two third of the notional profit, reduced by the portion of cash received to work certified may be transferred to the profit and loss account. In this case the formula to be used is as under: 2 Cash received Notional profit 3 (iv) Contracts nearing completion, say between 90% and 100% complete: When a contract is nearing completion or 90% or more work has been done on a contract. The amount of profit to be credited to profit and loss account may be determined by using any one of the following formula. (a) Estimated profit Contract price (b) Estimated profit Contract price Cash Work received certified or Estimated profit Contract price (c) Estimated Profit Cost of work to date Estimated total cos t Cost of work to date (d) Estimated profit Estimated total cost Cash received (e) Notional profit Contract price

6 7.6 Cost Accounting Question 4 Discuss the process of estimating profit/loss on incomplete contracts Process of estimating profit / loss on incomplete contracts (i) (ii) If completion of contract is less than 25% no profit should be taken to profit and loss account. If completion of contract is upto 25% or more but less than 50% then Cash received 1/3 Notional Profit may be taken to profit and loss account. (iii) If completion of contract is 50% or more but less than 90% then 2/3 Notional Profit Cash Work received certified may be taken to profit and loss account (iv) If completion of contract is greater than or equal to 90% then one of the following formulas may be used for taking the profit to profit and loss account. 1. Estimated Profit Contract price 2. Estimated Profit Contract price Cash Work received certified 3. Estimated Profit Cost of the work to date Estimated total cos t 4. Estimated Profit Cost of the work to date Estimated total cos t Cash received 5.

10 7.10 Cost Accounting 2. Profit to date (Notional Profit) and future profit are calculated as below: Profit to date (Notional Profit) = Estimated profit on the whole contract Cost Total Cost to date = ` ` 550 ` = ` (lakhs) Future Profit = ` ` = ` : = Cost of the contract to date + Profit to date = ` ` = ` lakhs 4. Degree of Completion of Contract to date: = Cost of the Contract to Contract Price date 100 = ` lakhs 100 =58.40% ` 1,100lakhs Question 7 A construction company undertook a contract at an estimated price of `108 lacs, which includes a budgeted profit of ` 18 lacs. The relevant data for the year ended are as under: (` '000) Materials issued to site 5,000 Direct wages paid 3,800 Plant hired 700 Site office costs 270 Materials returned from site 100 Direct expenses ,000 Progress payment received 7,200 A special plant was purchased specifically for this contract at ` 8,00,000 and after use on this contract till the end of , it was valued at `5,00,000. This cost of materials at site at the end of the year was estimated at ` 18,00,000. Direct wages accrued as on was ` 1,10,000. Required Prepare the Contract Account for the year ended 31 st March, 2002 and compute the profit to be taken to the Profit and Loss account.

11 Contract Costing 7.11 Dr. To Materials issued to site To Direct wages To Wages accrued To Plant hire To Site Office Costs To Direct expenses To Depreciation of special plant Contract Account for the year ended 31 st March, 2002 Cr. ` 000 ` 000 5,000 By Materials at site 1,800 3,800 By Materials returned By Cost of contract 8, ,680 10,680 To Cost of contract 8,780 By 10,000 To Profit & Loss A/c 1,200 (Refer to working note 2) To Work-in-progress c/d 20 (Profit in reserve) 10,000 10,000 Working notes Cost of work certified 1. Percentage of contract completion = 100 Value of the contract = 100 lacs 100 = 92.59% 108 lacs 2. Since the percentage of Contract completion is more than 90% therefore the profit to be taken to Profit and Loss Account can be computed by using the following formula. Cash received Profit to be taken to P & L A/c = Budged/Estimated Profit Contract price = 1,800 7,200 10,000 10,000 = 1,800 10,800 7,200 10,800 = ` 1,200 Question 8 Explain the following: (i) Notional profit in Contract costing (ii) Retention money in Contract costing

12 7.12 Cost Accounting (i) Notional profit in Contract costing: It represents the difference between the value of work certified and cost of work certified. Notional Profit = Value of work certified (Cost of works to date Cost of work not yet certified) (ii) Retention Money in Contract Costing: A contractor does not receive the full payment of the work certified by the surveyor. Contractee retains some amount to be paid after some time, when it is ensured that there is no default in the work done by the contractor. If any deficiency or defect is noticed, it is to be rectified by the contractor before the release of the retention money. Thus, the retention money provides a safeguard against the default risk in the contracts. Question 9 (a) Modern Construction Ltd. obtained a contract No. B-37 for ` 40 lakhs. The following balances and information relate to the contract for the year ended 31st March, 2008: Work-in-progress: 9,40,000 30,00,000 Work uncertified 11,200 32,000 Materials at site 8,000 20,000 Accrued wages 5,000 3,000 Additional information relating to the year are: Materials issued from store 4,00,000 Materials directly purchased 1,50,000 Wages paid 6,00,000 Architect s fees 51,000 Plant hire charges 50,000 Indirect expenses 10,000 Share of general overheads for B-37 18,000 Materials returned to store 25,000 Materials returned to supplier 15,000 Fines and penalties paid 12,000

13 Contract Costing 7.13 The contractee pays 80% of work certified in cash. You are required to prepare: (i) Contract Account showing clearly the amount of profits transferred to Profit and Loss Account. (ii) Contractee s Account.

Credit to Proift andloss Account = Estimated profit on completed contract Cash received Contract price Estimated profit on completed contract basis = Contract Price (Total expenditure to date + Estimated further expenditure to completed contract) = 32,50,000 (22,50, ,50,000) = ` 7,50, ,50,000 21,25,000 Credit to Proift and Loss Account = 7,50,000 =` 4,90,385 32,50,000 27,50,000

15 Contract Costing 7.15 Question 11 What is cost plus contract? State its advantages. Cost plus contract: Under cost plus contract, the contract price is ascertained by adding a percentage of profit to the total cost of the work. Such types of contracts are entered into when it is not possible to estimate the contract cost with reasonable accuracy due to unstable condition of material, labour services etc. Following are the advantages of cost plus contract: (i) The contractor is assured of a fixed percentage of profit. There is no risk of incurring any loss on the contract. (ii) It is useful specially when the work to be done is not definitely fixed at the time of making the estimate. (iii) Contractee can ensure himself about the cost of contract as he is empowered to examine the books and documents of the contractor to ascertain the veracity of the cost of contract. Question 12 Explain the importance of an Escalation Clause in contract cost. During the execution of a contract, the prices of materials, or labour etc., may rise beyond a certain limit. In such a case the contract price will be increased by an agreed amount. Inclusion of such a clause in a contract deed is called an Escalation Clause. Question 13 A contract expected to be completed in year 4, exhibits the following information: End of Year Value of work certified Cost of work to date Cost of work not yet certified Cash received ,000 50, ,00,000 2,30,000 10,000 2,75, ,00,000 6,60,000 20,000 7,50,000 The contract price is ` 10,00,000 and the estimated profit is 20%. You are required to calculate, how much profit should have been credited to the Profit and Loss A/c by the end of years 1, 2 and 3.

The contractee pays 75% of value of work certified, as and when certified and makes the final payment on the completion of contract. Following information is available for the first year: Cost of work-in-progress uncertified 8,000 Profit transferred to Profit & Loss A/c at the end of year I on incomplete contract 60,000 Cost of work to date 88,000 Calculate the value of work- in-progress certified and amount of contract price.

17 Contract Costing 7.17 As the contract is 80% complete, so 2/3 rd of the notional profit on cash basis has been transferred to Profit & Loss A/c in the first year of contract. Amount transferred to Profit & Loss A/c = 3 2 Notional Profit % of cost received 2 75 or, 60,000 = Notional Profit , or, Notional Profit = 2 75 = `1,20,000 Computation of Value of Work Certified Cost of work to date = ` 88,000 Add: Notional Profit = `1,20,000 `2,08,000 Less: Cost of Work Uncertified = 8,000 Value of Work Certified = `2,00,000 Since the Value of Work Certified is 80% of the Contract Price, therefore Value of Work Certified Contract Price = 80% `2,00,000 = = `2,50,000 80% Question 15 SB Constructions Limited has entered into a big contract at an agreed price of ` 1,50,00,000 subject to an escalation clause for material and labour as spent out on the contract and corresponding actuals are as follows: Material: Standard Quantity (Tonnes) Actual Quantity (Tonnes) Rate per Tonne Rate per Tonne A 3,000 1,000 3,400 1,100 B 2, , C 500 4, ,900 D , ,500 Labour: Hours Hourly Rate Hours Hourly Rate L 1 60, , L 2 40, ,000 35
