Scale Industry

Overhead is expenses incurred for carrying
out the production process and sale of finished goods. On the other hand
overhead is an indirect cost i.e. cost does not directly attributable to
any department. All overhead expenses must have identification for
department or product except in cases where this is not possible. Various
approach are used for allocate and apportionate overhead to the
department.
There is little difference between allocation and apportionment of
overhead. The dictionary meaning of allocation is 'To Place' and
dictionary meaning of apportionment is 'To Share'. According to ICMA
Terminology "The allotment of whole item of cost to cost centers or cost
unit is know as allocation." The term apportionment is defined as
allotment to two or more cost center or cost unit of a proportion of
common item of cost on estimated basis of benefit received. The service
department expenses have to be further apportioning to the department on
some equitable basis depending up on the nature and extent of service
rendered. The process of allocation or apportionment of overhead to the
department is called as departmentalization of overhead. These department
or product is called as cost center to which all cost is charged through
allocation and apportionment.
In perspective of India two approach is
famous to allocate and apportionate overhead viz. traditional approach and
modern approach (Activity Based Costing).
I. Traditional Approach:
This approach is very famous approach to allocate and apportionate
overhead up to 1950's in India. In this approach indirect cost that
directly identifiable to the department is allocate and expense incurred
for various department jointly have to be apportionate over each
department on proportionate basis. Proportion can be differing from
expense to expense. For examples:
|
|
Expense |
Basis for apportionment |
|
|
Rent |
Area occupied |
|
|
Lighting |
No. of switches |
|
|
Salary |
Time devoted |
|
|
Power |
No. of machine x Horse
power of machine |
It is necessary to take best suitable
proportion to apportionate overhead for ascertain cost. In this approach
every customer pay equal amount for product irrespective of facility
enjoyed.
II. Modern Approach (Activity Based
Costing):
With the rapid advancement in
industrialization with all its complexities a new approach is introduced
to allocate and apportionate overhead named Activity Based Costing. Under
this approach all indirect cost are traced to departments on the basis of
activity carried for production. The great advantage of this approach is
that customer who enjoyed more facility pay more and who enjoyed less
facility pay fewer amounts.
In both approach profit of the company is
same department-wise profit can be changed. Activity Based Costing (ABC
Technique) is world wide acceptable costing technique. Big manufacturing
concern can adopt ABC Technique because it evaluates correct performance
of each department.
In the perspective of India small-scale
industry can not adopt ABC Technique because it is very technical system
and require a person who has technical knowledge of ABC Technique. This
system is very expensive system because it require more cost records and
cost books. Small-scale industry can adopt a new technique named Hybrid
Technique easily. Under this approach some indirect expense who play
relevant role in ascertainment of cost apportionate on the basis of
activities and other expense apportionate on proportionate basis depending
up on the nature of expense. Hybrid technique is less expensive, less
technical and requires less costing records in compare to Activity Based
Costing.
Illustration:
A small-scale industry manufactures three
products A, B and C. Product A is manufacture in department X, product B
is manufacture in department Y and product C is manufacture in department
Z. there is two service department viz. canteen and maintenance.
