CHAPTER 10

PROCESS & OPERATION COSTING

CONCEPT 1: MEANING OF PROCESS COSTING


Process Costing is a method of costing used in industries where the material has to pass through

two or more processes for being converted into a final product.

It is defined as “a method of Cost Accounting whereby costs are charged to processes or

operations and averaged over units produced”.

Such type of costing method is useful in the manufacturing of products like steel, paper,

medicines, soaps, chemicals, rubber, vegetable oil, paints, varnish etc. where the production

process is continuous and the output of one process becomes the input of the following process

till completion.

This can be understood with the help of the following diagram:

Raw Finished
Material Process-I Process-II Process-III Goods

Basic Features

Industries, where process costing can be applied, have normally one or more of the following

features:

1. Each plant or factory is divided into a number of processes, cost centres or departments,

and each such division is a stage of production or a process.

2. Manufacturing activity is carried on continuously by means of one or more process run

sequentially, selectively or simultaneously.

3. The output of one process becomes the input of another process.

4. The end product usually is of like units not distinguishable from one another.

5. It is not possible to trace the identity of any particular lot of output to any lot of input

materials. For example, in the sugar industry, it is impossible to trace any lot of sugar bags

to a particular lot of sugarcane fed or vice versa.

6. Production of a product may give rise to Joint and/or By-Products.


Topper’s Classes Process & Operation Costing | 10.2
CONCEPT 2: COSTING PROCEDURE IN PROCESS COSTING
The Cost of each process comprises the cost of:

(i) Materials (ii) Employee Cost (Labour)

(iii) Direct expenses, and (iv) Overheads of production.

Materials: Materials and supplies which are required for each process are drawn against Material

Requisitions Notes from the stores. Each process for which the materials are used, are debited

with the cost of materials consumed on the basis of the information received from the Cost

Accounting department.

The finished product of first process generally become the raw materials of second process;

under such a situation the account of second process is debited with the cost of transfer from

the first process and also with the cost of any additional material used in process.

Employee Cost (Labour): Each process account should be debited with the labour cost or wages

paid to labour for carrying out the processing activities.

Sometimes the wages paid are apportioned over the different processes after selecting

appropriate basis.

Direct expenses: Each process account should be debited with direct expenses like depreciation,

repairs, maintenance, insurance etc. associated with it.

Production Overheads: Expenses like rent, power expenses, lighting bills, gas and water bills etc.

are known as production overheads. These expenses cannot be allocated to a process.

The suitable way out to recover them is to apportion them over different processes by using

suitable basis.

Usually, these expenses are estimated in advance and the processes debited with these expenses

on a pre- determined basis.

CONCEPT 3: STEPS OF PROCESS COSTING

1. Open a process A/c for every process and debit all the expenses.

2. Normal Loss % is estimated and accounted.

3. Calculate the Normal Cost / unit.


𝑇𝑜𝑡𝑎𝑙 𝐶𝑜𝑠𝑡 − 𝑁𝑜𝑟𝑚𝑎𝑙 𝐿𝑜𝑠𝑠 𝑟𝑒𝑐𝑜𝑣𝑒𝑟𝑒𝑑
= 𝑇𝑜𝑡𝑎𝑙 𝑢𝑛𝑖𝑡𝑠 – 𝑛𝑜𝑟𝑚𝑎𝑙 𝑙𝑜𝑠𝑠

4. Value the actual production units at Normal Cost.

5. Balancing figure of Process A/c will be Abnormal loss or Gain Valued at Normal cost.

CONCEPT 4: TREATMENT OF NORMAL, ABNORMAL LOSS AND ABNORMAL GAIN
Normal and Abnormal Loss

Loss of material is inherent during processing operation. The loss of material under different

processes arises due to reasons like evaporation or a change in the moisture content etc.

Process loss is defined as the loss of material arising during the course of a processing operation

and is equal to the difference between the input quantity of the material and its output.

There are two types of material losses viz.

(i) Normal loss and

(ii) Abnormal loss.

Normal Process Loss: It is also known as normal wastage. It is defined as the loss of material

which is inherent in the nature of work. Such a loss can be reasonably anticipated from the nature

of the material, nature of operation, the experience and technical data.

It is unavoidable because of nature of the material or the process. It also includes units

withdrawn from the process for test or sampling.

Treatment in Cost Accounts: The cost of normal process loss in practice is absorbed by good

units produced under the process. The amount realised by the sale of normal process loss units

should be credited to the process account.

Problem.4.1: (Normal loss with no realisable value)


A product passes through Process- I and Process- II. Materials issued to Process- I amounted to

₹ 40,000, Wages ₹30,000 and manufacturing overheads were ₹ 27,000. Normal loss anticipated

was 5% of input. 4,750 units of output were produced and transferred-out from Process-I. There

were no opening stocks. Input raw material issued to Process I were 5,000 units. Scrap has no

realisable value.

You are required to PREPARE Process- I account, value of normal loss and units transferred to
Process-II.

× Units transferred
₹ 97,000−₹ 500
= 5,000 𝑢𝑛𝑖𝑡𝑠−250 𝑢𝑛𝑖𝑡𝑠 × 4,750 units = ₹ 96,500

CONCEPT 5: ABNORMAL PROCESS LOSS


It is also known as abnormal wastage. It is defined as the loss in excess of the pre-determined

loss (Normal process loss). This type of loss may occur due to the carelessness of workers, a bad

plant design or operation, sabotage etc.

Such a loss cannot obviously be estimated in advance. But it can be kept under control by taking

suitable measures.
Topper’s Classes Process & Operation Costing | 10.7
Treatment in Cost Accounts: The cost of an abnormal process loss unit is equal to the cost of a

good unit. The total cost of abnormal process loss is credited to the process account from which

it arises. Cost of abnormal process loss is not treated as a part of the cost of the product. In

fact, the total cost of abnormal process loss is debited to costing profit and loss account.

CONCEPT 6: ABNORMAL PROCESS GAIN/ YIELD


Sometimes, loss under a process is less than the anticipated normal figure. In other words, the

actual production exceeds the expected figures.

So, abnormal gain may be defined as an unexpected gain in production under the normal conditions.

This arises due to over- estimation of process loss, improvements in work efficiency of workers,

use od better technology in production etc.

Treatment in Cost Accounts: The process account under which abnormal gain arises is debited

with the abnormal gain and credited to abnormal gain account which will be closed by transferring

to the Costing Profit and Loss account. The cost of abnormal gain is computed on the basis of

normal production.

CONCEPT 8: VALUATION OF WORK-IN-PROCESS


The cost incurred in such industries represents the cost of work carried on opening work-in-

process, closing work-in-process and completed units.

Thus to ascertain the cost of each completed unit, it is necessary to ascertain the cost of work-

in-process in the beginning and at the end of the process.

Equivalent Units

Equivalent units or equivalent production units, means converting the incomplete production units

into their equivalent completed units.

Under each process, an estimate is made of the percentage completion of work-in-process with

regard to different elements of costs, viz., material, labour and overheads.

The formula for computing equivalent completed units is:

𝑨𝒄𝒕𝒖𝒂𝒍 𝒏𝒖𝒎𝒃𝒆𝒓 𝒐𝒇 𝒖𝒏𝒊𝒕𝒔 𝒊𝒏 𝑷𝒆𝒓𝒄𝒆𝒏𝒕𝒂𝒈𝒆 𝒐𝒇


Equivalent completed units = ( ) × ( )

CONCEPT 10: PROCESS COSTING METHODS


Mainly two methods for valuation of work-in-process are followed:

1. First-in-First Out (FIFO) method.

2. Weighted Average (Average) method


Topper’s Classes Process & Operation Costing | 10.28
CONCEPT 11: FIFO METHOD
Under this method the units completed and transferred are taken from both opening work-in-

process (WIP) and freshly introduced materials/inputs. The cost to complete the opening WIP

and other completed units are calculated separately.

The cost of opening WIP is added to cost incurred on completing the incomplete (WIP) units into

complete one.

The total cost of units completed and transferred is calculated by adding opening WIP cost to

cost on freshly introduced inputs. In this method the closing stock of work in process is valued

at current cost.

Method of Cost Formula:

FIFO

 Opening WIP will be completed firstly in current period

 then work on new Raw Material will start.

Working Notes:

- Cost / Unit

= Total Current period cost – Normal Loss real / Total Equivalent units

- Working Note

Cost of unit completed will include

(i) Opening WIP pre period cost

(ii) Opening Work in Progress current period cost

(iii) Units Introduced and Completed during the period cost

Note: Normal Loss % can be

1. Of current period units introduced = Input × %

2. Of units Introduced × Opening WIP = (Opening WIP + Introduced) × %

3. Of units produced = (Opening WIP + Input) – Closing WIP × %

So, (i) Equivalent Production = 15060 units

(ii) Cost per equivalent unit = ₹ 212

CONCEPT 12: AVERAGE COST METHOD


Under this method, the cost of opening work-in-process and cost of the current period are

aggregated and the aggregate cost is divided by output in terms of completed units.

The equivalent production in this case consists of work-load already contained in opening work-

in-process and work-load of current period.

The main difference between FIFO method and average method is that units of opening work in

process and their cost are taken in full under average method while under FIFO method only the

remaining work done now is considered.

(i) Add opening WIP in current year Units Introduced.

(ii) Add opening WIP previous year cost in current year cost element wise.

Cost / unit: Opening WIP previous year + Current Year WIP / Eq. units

Note:

 In WIP, M1 (coming from previous process) is generally assumed 100% Completed, % of

Material given is used for M2.

 Packing Material Cost will only be added on Finished stock.

Normal process loss may be estimated to be 10% of material input. It has no realizable value. Any

loss over and above normal loss is considered to be 100% complete in material and processing.

The Company transfers 60,000 kgs. of output (Chemical G) from Process I to Process II for

producing Chemical ‘GK’. Further materials are added in Process II which yield 1.20 kg. of Chemical

‘GK’ for every kg. of Chemical ‘G’ introduced.

The chemicals transferred to Process II for further processing are then sold as Chemical ‘GK’

for ₹ 10 per kg. Any quantity of output completed in Process I, are sold as Chemical ‘G’ @ ₹ 9 per

kg. The monthly costs incurred in Process II (other than the cost of Chemical ‘G’) are:

Input 60,000 kg. of Chemical ‘G’

Materials Cost ₹ 85,000

Processing Costs ₹ 50,000

You are required:

(i) Prepare Statement of Equivalent production and determine the cost per kg. of Chemical,

‘G’ in Process I using the weighted average cost method.

(ii) Prepare a statement showing cost of Chemical ‘G’ transferred to Process II, cost of

abnormal loss and cost of closing work-in-progress.

CONCEPT 13: INTER PROCESS PROFIT


To control cost and to measure performance, different processes within an organization are

designated as separate profit centres.

In this type of organizational structure, the output of one process is transferred to the next

process not at cost but at market value or cost plus a percentage of profit.

The difference between cost and the transfer price is known as inter-process profits.

Advantages:

1. Comparison between the cost of output and its market price at the stage of completion is

facilitated.

2. Each process is made to stand by itself as to the profitability.

Disadvantages:

1. The use of inter-process profits involves complication.

2. The system shows profits which are not realised because of stock not sold out.

CONCEPT 14: OPERATION COSTING


This product costing system is used when an entity produces more than one variant of final

product using different materials but with similar conversion activities. Which means conversion

activities are similar for all the product variants but materials differ significantly.

Operation Costing method is also known as Hybrid product costing system as materials costs are

accumulated by job order or batch wise but conversion costs i.e. labour and overheads costs are

accumulated by department, and process costing methods are used to assign these costs to

products.
Topper’s Classes Process & Operation Costing | 10.53
Moreover, under operation costing, conversion costs are applied to products using a

predetermined application rate. This predetermined rate is based on budgeted conversion costs.

For example, a company is manufacturing two grades of products, Product- Deluxe and Product-

Regular.

Both the products pass through a similar production process but require different quality and

quantities of raw materials. The cost of raw material is accumulated on the basis of job or batches

or units of two variants of products. But the costs for the conversion activities need not to be

identified with the product variants as both the Products requires similar activities for

conversion.

Hence, conversion activity costs are accumulated on the basis of departments or processes only.

Example of industries are ready made garments, Shoe making, jewelry etc.
