INTRODUCTION Information is very important to ensure effective management. Thus,
cost accounting is needed in exercising the management functions of planning, decision making and control.
In today’s competitive environment the costing become more complex due to several factors such as expansion of business, market become more sophisticated, advanced in technology, newly introduced legislation to regulate the business and employees and management become more cost conscious.
All business organization services, retail, and manufacturing need to provide cost information in order to help them in making decision especially in determining the selling price. Therefore, costing is essential for the survival of an organization.

Def of Costing :
the ascertainment of cost. The costs are ascertained by applying accounting and costing
principles, methods & techniques. Cost are ascertained after they are incurred or
before they are incurred (estimates)

1. Cost :
The amount of actual expenditure incurred on to a specific thing or activity.

1.5 – COSTING PRINCIPLES & CONCEPT
2. Cost Unit :
A quantitative unit of product or services to which cost can be ascertained.
Example of cost unit:

Cost Unit Uses
Kilowatt Hours To determine electricity costs
Litres To determine cost of petrol / liquid
Consulting hours To determine codst of treating a patient by a medical clinic

1.7 – CLASSIFICATION & TYPES OF COST
Cost are classified depending on the purpose for which details are required.
It can be classified as:
1)Cost behavior
2)Cost Function
3)Controllable & uncontrollable cost , Normal & abnormal cost.
22
Cost may or may not vary with the level of activity.
The level of activity : refer to volume of production or number or value of items sold.
Managers have knowledge about company’s cost behavior so that he may predict the impact of his decisions on profit and in controlling costs.
1)Cost Behavior

4 types of costs4 types of costs
Fixed Costs
Variable costsSemi variable costs/
Semi fixed costs/ mixed cost
Step costs
24
Fixed cost
Definition : the cost that remain constant over a wide range of activity for a specified time.
Example :
a) depreciation
b) supervisory salary & director salary
c) insuranceFixed cost/unit varies
according to the level of activity.

Variable Cost
Definition : the cost that varies in direct proportion to changes in the level of activity (volume)
Example :
a) direct material
b) direct labour
c) direct expensesVariable cost/unit remain
constant unless of the changes in the level of activity/ volume.

Step Cost
These costs are fixed over a range of activity and then rises to a new level as activity changes.
Eg : A production supervisor
may supervise a given no of workers. No of workers increase due to increase production it is necessary to hire another supervisor. Thus, supervisor salaries are step costs.

Ways of segregating Mixed Cost
Linear Cost Function:3 methods of
segregating the mixed costs are :
i) Scatter graph
ii) Least squares method
iii) High-low method – only discuss this method.
y = a + bx
Where,y = Total Costa = fixed costb = variable cost/unitx = volume
29
High-low method
Step 1 : Identify the highest & lowest level of activity.
Step 2 : Compare the associated costs with relevant levels of activity in the form of a ratio or fraction to get the variable cost per unit :
Variable Cost/unit = Difference in cost Difference in activity
Variable cost/unit = Highest cost – lowest cost Highest activity – lowest activity
30
Cont’
Step 3 : Substitute the variable cost/unit in the following equation to get the total fixed asset cost –
Total Cost = Total Fixed Cost (TFC) + Total Variable Cost (TC) (TVC)
TC = TFC + (Variable Cost per unit x Volume)
TFC = TC - TVC
31
a) Production Cost – Costs involved in production such as direct material, direct labour, direct expenses which is called prime cost and also production overhead that comprise of indirect material, indirect labour and indirect expenses. A combination of prime cost & production overhead is called FACTORY/ MANUFACTURING/PROCUCTION COST

3)Controllable & uncontrollable cost, Normal & abnormal Cost
a) Controllable Cost – can be influenced by the decisions or actions of top management.
Example : labor cost is controllable by the service manager by controlling such factors as efficiency, idle time, overtime & so on.
b) Uncontrollable Cost – cannot be influenced by the decisions or actions of top management
Example : increased price of raw material due to inflation.
36
c) Normal Cost – is expected & planned for at a given level of output & cannot be avoided.Example : loss of liquid such as petrol that evaporates under efficient working condition.
d) Abnormal Cost – is not expected to occur under efficient operating conditions which can be avoided.Example : loss of production due to machine breakdown or due to use of low quality of material.
