What Is a Contract Account?

When a contractor has accepted a contract, a separate account is opened for each contract, bringing together all the costs relating to a particular contract.

A serial number is assigned to each contract, which is known as a contract account.

Explanation of Contract Account

All expenses incurred in fulfilling a contract (e.g., materials, wages, direct expenses, cost of sub-contracts, cost of special plants, and indirect expenses) are debited to a contract account.

Similarly, expenses accrued or outstanding on the contract at the end of the accounting period are also debited to the contract account.

At the end of the accounting period, the following will appear on the credit side of the account:

  • Materials returned to the supplier
  • Materials and plant returned to store
  • Materials transferred to other contracts, stolen, destroyed, sold, or in hand

Materials and plant stolen or destroyed are abnormal losses and should be charged to the profit and loss account.

Similarly, profit or loss arising from the sale of the plant or materials should also be transferred to the profit and loss account by way of abnormal items.

The other items to be shown on the credit side of the contract account are contract price (in completed contracts) and the work-in-progress, which consists of the value of certified work and the cost of uncertified work (in incomplete contracts).

Example of Contract Account

An example of a contract account is given below.

Treatment of Specific Items in a Contract Account

This section provides an overview of the treatment of the various items that are included in the contract account.

Materials

The cost of materials purchased directly or issued from stores will appear on the debit side of the contract account. Materials returned to suppliers and stores will appear on the credit side.

Amounts received from the sale of surplus materials will be credited to the contract account, while any profit or loss arising from them is to be transferred to the profit and loss account by way of abnormal items.

Materials that are lost, stolen, or destroyed by accident (e.g., in a fire) will be charged to the profit and loss account by way of abnormal loss.

The values of the material in hand at the end of the accounting period will appear on the credit side of the contract account.

Sometimes, materials are transferred from one contract to another contract. If so, then the contract receiving the materials is debited and the contract sending the materials is credited.

The following example shows how different material items should be treated in the contract account.

Example

A company undertook Contract No. 5 for the construction of a cinema building. He purchased materials for the contract at a cost of $80,000.

Issues from stores were $45,000. Materials valued at $3,000 were returned to stores, while materials costing $2,000 were stolen and those costing $500 were destroyed by fire.

Materials costing $5,000 were sold for $4,800. Materials worth $25,000 were received from Contract No. 3, which was completed. Materials worth $1,000 were transferred to Contract No. 15.

Materials in hand at the end of the accounting period were valued at $10,000.

Based on the above information, show the treatment of the materials in Contract Account No. 5.

Labor Cost

Every worker who is engaged at the site of a particular contract, irrespective of the nature of the work they perform, is treated as a direct worker, and they receive their wages as direct wages.

Such wages are to be charged to the particular contract directly.

If a worker (generally the supervisory staff) is engaged at two or more contracts, his total wages may be apportioned to different contracts based on the time devoted to each one (or on some other equitable basis).

Wages accrued or outstanding at the end of the accounting period should appear on the debit side of the contract account.

Example

The following data are available for the year ending 31st March 2019, relating to Contract No. 2, which commenced on 1st April 2018.

Direct wages accounted for $85,000, while wages accrued totaled $12,000.

Treatment of Labor Costs in Contract Account

Special Plant

The plant purchased by a contractor to execute the contract may be divided into two parts: special plant and general plant.

Special plants are specifically purchased for a particular contract, and they are expected to be used for that contract over a long period.

The value of the special plant at the start of the use period (i.e., the original cost including installation charges or written down value) is debited to the contract account.

At the end of the accounting period, the value of the plant after providing an appropriate amount of depreciation (i.e., depreciated value) should be credited to the contract account.

In this way, the depreciation on the plant is automatically charged to the contract account.

When calculating the value of plant in hand, the value of plant returned to store, plant sold, and plant destroyed, among others, should also be considered.

Example

A plant costing $80,000 was purchased for Contract No. 5 on 1st April 2019.

Also, a plant worth $4,000 was returned to store, while a plant costing $4,000 was sold for $6,000. A plant worth $2,000 was stolen, and one worth $8,000 was destroyed by fire.

The value of plant in hand at the end of the year 31st March 2020 was $40,000.

Show how the plant would be treated in Contract Account No. 5.

Example

A company purchased a plant for Contract No. 5 on 1st July 2019 at a cost of $40,000.

Show the treatment of plant in the contract account by depreciating it by the following:

  • 10%
  • 10% per annum

You should assume that the company's accounts are closed on 31st March each year.

Solution 2 for Treatment of Special Plants in Contract Account

Example

A contractor purchased a plant on 1st April 2019 for Contract No. 3 at a cost of $100,000. A plant costing $20,000 was returned to stores on 31st December 2019.

A plant costing $5,000 was lost in an accident on 30th September 2019. Also, a plant costing $10,000 was found to be unsuitable and sold immediately at $11,500.

Show the treatment of the plant by providing depreciation at 20% per annum. The books are closed on 31st March each year.

General Plant

In contrast to a special plant, a general plant is purchased for use at two or more contracts.

For a general plant, an hourly, daily, weekly, or monthly rate of depreciation should be determined, and the amount of depreciation can be charged to each contract according to the actual use of the plant at the site of the contract.

The treatment of depreciation for a general plant is illustrated in the next example.

Example

A plant was purchased for $52,000 on 1st April 2019. The plant's expected life was 5 years, and at the end of the 5th year, its scrap value will be $2,000.

The plant was used for 73 days for Contract No. 31. Show the treatment of plant in Contract Account No. 31.

Direct Expenses

All expenses that have been incurred specifically for a particular contract (other than material cost and direct wages) are direct expenses, and they should be debited to the contract account.

Examples of direct expenses include hire charges of special plant (not owned), carriage on materials purchased, and travel expenses relating to the contract.

Indirect Expenses

Some expenses can't be directly charged to a particular contract, including the salary of the general manager, the salary of an architect engaged at several contracts simultaneously, the salary of a store-keeper, and store and office expenses.

Since these expenses are incurred for the business as a whole, they are to be apportioned to the different contracts on some equitable basis.

Cost of Sub-Contracts

Generally, work of a specialized character (e.g., road construction, installation of lifts, and use of electrical fittings) is passed onto another contractor by the main contractor.

In such cases, the work performed by the sub-contractor forms a direct charge to the contract concerned, and the sub-contract price paid should be debited to the contract account.

Cost of Extra Work

Sometimes in a contract, the contractee may require additional work (or variations on the work originally contracted).

Since the additional work required will not be covered by the terms and conditions of the original contract, it will be the subject of a separate charge.

If the additional work is substantial, it should be treated as a separate contract and dealt with in a separate account.

If the additional work is not substantial, the expenses incurred on extra work should be debited to the contract account as cost of extra work.

The extra amount that the contractee has agreed to pay to the contractor should be added to the original contract price.

Contract Price

The contract price is the agreed price at which the contractor undertakes to execute the contract.

The contract account is credited with the contract price if it has been completed. In such a case, the amount of contract price is debited to the contractee's personal account and credited to the contract account.

In incomplete contracts, no entry is passed in respect of the contract price.

Work-In-Progress

For an incomplete contract, the amount of work-in-progress to be included on the credit side of the contract account comprises:

  • Work certified
  • Work done but not certified

    (i) Work Certified

In large contracts, the contractor periodically receives sums of money from the contractee. These sums are paid against invoices issued by the contractee's architect, surveyor, or engineer regarding the value of the work completed so far.

The work completed by the contractor and certified to be complete by the contractee's architect or engineer is classed as work certified (or work completed and certified).

(ii) Work Done but Not Certified

    Work relating to an incomplete contract that has been done but has not yet been certified by the contractee's engineer or architect is known as uncertified work (or work done but not certified).

    Work done but not certified is the work done since the most recent certification, and it should be valued based on the actual cost.

    In an incomplete contract, the amount of work-in-progress (i.e., both work certified and work done but not certified) at the end of the accounting period is debited to the work-in-progress account and credited to the contract account.

    At the beginning of the next accounting period, this amount is debited to the contract account and credited to the work-in-progress account.

    Retention Money

    Generally, contract terms specify that the whole of the amount shown by the architect's certificate will not be paid to the contractor.

    Instead, a specified percentage (e.g., 10% or 20%) will be retained by the contractee until completion.

    The money that is retained in this way is referred to as retention money.

    To consider an example, suppose that the the total value of work certified is $100,000, and it is agreed that 20% of the work certified shall be retained till the completion of the contract.

    In this example, the contractee will pay $80,000 to the contractor immediately, keeping $20,000 (20% of $100,000) as retention money until the completion of the contract.
