12.1  INTRODUCTION
Unit costing is one of the most commonly used method of costing by firms 
which are engaged in manufacturing products with identical units such as 
coal, bricks, shoes, sugar, cement, etc. Under this method, cost and profi t 
per unit of output is ascertained by preparing monthly or quarterly cost 
sheets showing details of the various components of total cost. In this unit, 
you will learn how cost sheet is prepared and how cost and profit per unit of 
output is determined.
12.2  MEANING AND APPLICABILITY 
Unit costing refers to a method of costing used by industries engaged in 
mass production of homogeneous/identical products. The basic feature of 
unit costing is that the cost units are identical. Unit costing is also known 
as “Single Output Costing”. Single or Output Costing is the form of Unit 
costing used when the enterprise produces basically one homogeneous 
product or one homogeneous product in two or more grades. Under this 
method, the cost per unit is arrived at by dividing the total cost by the 
total number of units produced. Thus, the cost ascertainment involves the 
following two stages: 
i)  collection and functional analysis of all costs, 
ii)  division of total cost by the total number of units produced in order 
to determine the cost per unit. 
This procedure is applicable only when the organisation produces only one 
product. If, however, the organisation produces several grades of the same 
product, it becomes imperative to apportion the various costs between the 
various grades so that the Cost of each grade can be determined separately
Unit costing method can be successfully applied in those industries engaged 
in assembling, such as automobiles, electronics, typewriters, etc., and also 
in those industries engaged in production of homogeneous products, such as 
collieries, quarries, brick making, brewaries, dairies, sugar, cement works 
etc. 
12.3  PREPARATION OF STATEMENT OF COST/ COST 
SHEET 
Under this method of costing, it is customary to prepare a statement of cost 
which is popularly known as ‘Cost Sheet’ at periodical intervals. It shows 
detailed break-up of the total cost and the cost per unit at each stage. It 
should contain as much information regarding costs as may be necessary 
for the purposes of cost analysis and cost control. In actual practice, the 
corresponding figures of the preceding period are also shown in the) Cost 
Sheet for purposes of comparison. This facilitates cost control. 
You learnt about the preparation of Cost Sheet in Unit 3 Block 1. We shall 
now study about it in more detail. The proforma of Cost Sheet is given here

12.3.1  Ascertainment of Cost of Direct Materials 
While considering the cost of direct materials, only the cost of direct materials 
actually used or consumed should be taken into account. Normally, all the 
raw materials purchased in a particular period are not consumed during the 
same period. Certain amount of raw materials is always kept in stock so that 
production may not be interrupted for want of materials. In most cases, the 
cost of direct materials actually used in production is not given. It should be 
determined in the following manner:

12.3.1  Ascertainment of Cost of Direct Materials 
While considering the cost of direct materials, only the cost of direct materials 
actually used or consumed should be taken into account. Normally, all the 
raw materials purchased in a particular period are not consumed during the 
same period. Certain amount of raw materials is always kept in stock so that 
production may not be interrupted for want of materials. In most cases, the 
cost of direct materials actually used in production is not given. It should be 
determined in the following manner: 
Cost of Direct Materials Used in Production     Rs. 
Cost of Opening Stock of Raw Materials                          …….. 
Add : Cost of Raw Materials purchased            …….. 
Add : Carriage/Freight on purchases, if any      ……..     …….. 
Cost of Raw Materials available for use                            ……..
Less: Cost of Closing Stock of Raw Materials                  ……..    ……..

worked out.

V alue of stock of raw materials may be determined in any one of the methods 
discussed in Unit 5 on materials. However, in the absence of any indication 
in the given problem, it would be better to value the stock of raw materials 
on FIFO basis and to give a note to that effect. 
12.3.2  Ascertainment of Cost of Direct Labour 
While considering the cost of direct labour, only the cost of direct labour actually 
used in production should be taken into account. If there are outstanding or 
prepaid direct wages, the same should be adjusted in the following manner: 
Cost of Direct Labour Used in Production                              Rs.   
Direct Wages paid      ……… 
Add: Outstanding Direct Wages, if any   ………
