Cost Accounting
An Introduction 
Introduction 
 Cost  is  a  measurement,  in  monetary  terms,  of 
the amount of resources used for the purpose of 
production of goods or rendering services. 
 Cost  is  the  amount  of  actual  or  notional 
expenditure  relating  to  a  product,  job,  service, 
process or activity. 
 Cost is often used as a generic term to describe 
various types of costs. 
 Costing  is  the  technique  and  process  of 
ascertaining costs. 
Introduction 
 Cost  Accounting  is  the  process  of  accounting  from  the 
point  at  which  expenditure  is  incurred  or  committed  to 
the  establishment  of  its  ultimate  relationship  with  cost 
centers and cost units. It includes: 
 Collecting, classifying, recording, allocating and analyzing costs 
 Preparation of periodical statements and reports for ascertaining 
and controlling costs 
 Application of cost control methods 
 Ascertainment of profitability of activities carried out or planned. 
 Cost  Accounting  is  the  processing  and  evaluation  of 
monetary  and  non-monetary  data  to  provide  information 
for  internal  planning,  control  of  business  operations, 
managerial decisions and special analysis. 
Introduction 
 Cost  Accountancy  is  the  application  of  costing  and  cost 
accounting  principles,  methods  and  techniques  to  the

Cost Treatment 
 Cost Ascertainment is the process of determining actual 
costs after they have been incurred. 
 Cost  Estimation  is  the  process  of  determining  future 
costs  in  advance  before  production  starts,  on  the  basis 
of  actual  past  cost  adjusted  for  anticipated  future 
changes. 
 Cost Allocation is the process of charging the full amount 
of an individual item or cost directly to the cost center for 
which the item of cost was incurred. 
 Cost  Apportionment  is  the  process  of  charging  the 
proportion  of  common  items  of  cost  to two  or  more  cost 
centers on some equitable basis. 
 Cost  Absorption  is  charging  cost  from  cost  centers  to 
products  or  services  by  means  of  a  pre-determined 
absorption rate.

Techniques of Inventory Control 
 ABC Analysis 
 Economic Order Quantity (EOQ) 
 Stock  Levels    minimum,  maximum,  reorder  level, 
reorder quantity 
 Inventory Turnover Ratio 
 Slow and Non-Moving Items 
 Purchase, Storage and Issue Procedure 
 Two Bin System 
 Perpetual  Inventory  Records  and  Continuous  Stock 
Verification 
 Budgetary System 
ABC Analysis 
 A: 70% value, 10% items 
 B: 20% value, 20% items 
 C: 10% value, 70% items 
 Ensures control on high value items 
 Saves time and cost of monitoring 
 Reduces total investment in inventory 
 Facilitates faster decision making 
 Better utilization of resources 
 Better physical control of stock 
Economic Order Quantity (EOQ) 
 Level  at  which  the  ordering  and  carrying  costs  are 
minimum.  At  EOQ,  the  ordering  and  carrying  costs  are 
equal. 
 Ordering  Cost  includes  costs  for  placing  an  order, 
transportation, receiving goods and inspecting goods 
 Ordering Cost reduces with order size 
 Carrying Cost includes costs for storage space, handling 
materials, insurance, obsolescence and personnel. 
 Carrying Cost increases with order size 
 Dependent  on  periodicity  and  annual  material 
consumption 
 EOQ determines quantity to be ordered at a given time 
EOQ Technique 
 Assumes  prior  knowledge  of  annual  usage,  constant  usage  rate, 
constant  ordering  cost,  constant  carrying  cost  and  zero  lead  / 
delivery time 
 EOQ can be determined by graphical, tabular or formula method 
 Find the level at which total of ordering and carrying cost is least or 
ordering cost equals carrying cost 
 EOQ  =    (2AO  /  C)  where  A  =  Annual  Consumption,  O  =  Ordering 
Cost per order and C = Carrying Cost per order 
 EOQ = (2AO/IP) where I = Inventory or Stock Holding Cost (as % 
of average stock value) and P = Price per unit 
 Economic Order Frequency (in days) = 365 / (Number of orders per 
year) 
 Total annual ordering and carrying cost at EOQ = (2AOC) 
Stock Levels 
 Maximum  Stock  Level  is  the  maximum  stock 
level that can be held in store. 
 It  avoids cost  of  over-stocking  such as  costs for 
storage,  investment,  insurance  and  risk  of  
obsolescence 
 Dependent  on  reorder  level,  reorder  quantity, 
rate  of  consumption,  reorder  period,  availability 
of  funds  and  storage  space,  cost  of  storage, 
insurance, obsolescence, price fluctuation, etc 
 Formula:  Maximum  Level  =  Reorder  Level  + 
Reorder  Quantity    (Minimum  Consumption  x 
Minimum Reorder Period) 
Stock Levels 
 Minimum  Stock  Level is  the  level  below  which the  stock 
should not be allowed to fall 
 Dependent  on  reorder  level,  rate  of  consumption  and 
reorder period 
 Formula:  Minimum  Level  =  Reorder  Level    (Normal 
Consumption x Reorder Period) 
 Reorder  Level  is  the  level  of  stock  at  which  fresh 
replenishment order should be placed 
 Dependent  on  consumption  rate,  reorder  period  and 
minimum level 
 Formula:  Reorder  Level  =  Maximum  Consumption  x 
Maximum Reorder Period OR Minimum Level + (Normal 
Consumption x Reorder Period) 
Stock Levels 
 Average  Stock  Level  =  Minimum  Level  +    Reorder 
Quantity OR (Minimum Level + Maximum Level) / 2 
 Danger  Level  is  the  level  at  which  only  emergency 
material issue is done (normal material issue is stopped) 
 It is a level at which urgent ordering action is required  
 If  Danger  Level  is  below  Minimum  Level,  urgent 
corrective action is required 
 If  Danger  Level  is  above  Minimum  Level,  it  calls  for 
preventive action 
 Dependent on rate of consumption and reorder period 
 Formula:  Normal  Consumption  Rate  x  Maximum 
Reorder Period for emergency purchases 
Inventory Turnover Ratio 
 Indicates the speed with which inventory is consumed 
 A  high  ratio  indicates  fast  moving  stock,  low  ratio 
indicates slow moving stock 
 Inventory  Turnover  Ratio  =  Materials  Consumed  / 
Average Stock Held expressed in times 
 Materials  Consumed  =  Opening  Stock  +  Purchases   
Closing Stock 
 Average Stock =  (Opening Stock + Closing Stock) 
 Days of Inventory = 365 / Inventory Turnover Ratio 
 Can  be  computed  for  stock  categories  to  determine  fast 
moving, slow moving, dormant or obsolete stock 
 Ideal  level  is  determined  with  reference  to  level  of  other 
firms or the industry average 
Other Techniques 
 Two Bin System  Bin has two parts, the smaller one for 
reorder  stock  level  and  the  other  for  the  remaining 
material 
 Issues  are  made  from  the  larger  bin,  fresh  order  placed 
when it become empty, material used from smaller bin till 
replacement received and filled 
 Periodic  Inventory  System    Physical  stock  taking  done 
periodically, requiring shut down 
 Records then physically reconciled 
 Perpetual Inventory System  Records updated at every 
receipt and issue 
 Done using bin cards and stores ledger 
 Continuous  stock  taking  done  by  random  checks  of  the 
bin cards and stores ledger
