6. OBJECTIVES OF COST
ACCOUNTING
1. Ascertainment of cost of product or service
2. Valuation of inventories
3. Providing data for planning, control and
decision making
7. Ascertainment of cost of
productservice
Measurement of various elements of costs
1. Materials, 2. Labour (Manpower costs), 3. Expenses
(overheads)
Accounting for losses
a) Normal loss, b) Abnormal loss
Fixation of price to be charged to the customers
C+P= S
S-C= P
S-P= C
8. Valuation of inventories
Raw materials
Work in process
Finished goods
FIFOLIFOWeighted average cost
9. Providing data for planning, control
and decision making
Introduction of a new product
Discontinuing or closing a product
Further processing of a product
Opening a new sales office or branch

16. Direct and indirect materials
Direct materials- which can be directly allocated
to a cost centre or a cost object
Illustration- Raw materials used- Plastic in toys
or bottles, steel in kitchen utensils, gold in gold
necklace
Indirect materials- which cannot be identified in
or allocated to a product
Illustration- cotton waste, lubricants, spares
17. Direct and indirect wages
Direct labour cost- wages of those workers who
are readily identified or linked with a cost
centre or cost object
Indirect labour cost- wages of the workers which
are not directly allocable to a particular cost
centre – factory security staff or maintainance
staff salaries
18. Direct and indirect expenses
Direct expenses- which can be linked to a
product
Illustration- Hire charges of a mould, royalties to
collaborator, job processing charges
Indirect expenses- which cannot be directly
allocable to a product
Illustration- Factory power, insurance, repairs
20. Fixed costs
Cost which does not vary with the change in volume
of activity
Factory or office rent, audit fees, permanent staff
salaries, depreciation
21. Variable costs
Costs which tend to directly vary with the volume of
activity
Raw materials consumed, wages on piece rate basis,
sales commission
22. Semi variable costs
Costs which contain both fixed and variable elements.
They are partly affected by fluctuation in the level of
activity
Power, salesmen remuneration (fixed
salary+commission on sales)
23. Controllability classification
Controllable costs- discretion of management
Illustration- Sponsorship of an event, outbound
or offshore picnic for staff
Uncontrollable- No option or discretion
Illustration- Lease rent, property taxes, allocated
costs from the view point of product manager
24. Conversion costs
Costs which are
necessary to convert
raw materials into
finished products-
Direct labour costs
and manufacturing
overheads
29. Notional cost
It is an imaginary cost
which is included in the
cost units or cost centres
especially when its
performance is
measured with
competitors which are
not enjoying the same
benefits
e.g. rent, interest
32. Sunk cost
A cost that has already
been incurred and
which cannot be
recovered-
Inventory, R & D,
Asset discarded
33. Capacity costs
Capacity costs tend to be
fixed in relation to
changes of activity
within short term
periods
Over long term periods of
several years,
significant changes in
demand will cause
capacity costs to change
37. Target costs
Maximum amount of
cost that can be
incurred and with it a
firm can still earn the
required profit
margin at a particular
selling price
38. Step costs
A step cost is a cost
that does not change
steadily with changes
in activity volume,
but rather at discrete
points-
School picnic- buses
Hospital- no of nurses
39. Relevant and Irrelevant costs
Costs which are are
not relevant to the
decision are relevant
and irrelevant costs
e.g. cost of raw
material in stock in
respect of product
discontinued
