CLASSIFICATION OF COSTING

We first classify costs according to the three elements of cost:
a) Materials b) Labour c) Expenses

Product and Period Costs: We also classify costs as either
1 Product costs: the costs of manufacturing our products; or
2 Period costs: these are the costs other than product costs that are charged to,
debited to, or written off to the income statement each period.

The classification of Product Costs:

Direct costs: Direct costs are generally seen to be variable costs and they are called direct costs because they are directly associated with manufacturing. In turn, the direct costs can include:

• Direct materials: plywood, wooden battens, fabric for the seat and the back, nails, screws, glue.
• Direct labour: sawyers, drillers, assemblers, painters, polishers, upholsterers
• Direct expense: this is a strange cost that many texts don't include; but (International Accounting Standard) IAS 2, for example, includes it. Direct expenses can include the costs of special designs for one batch, or run, of a particular set of tables and/or chairs, the cost of buying or hiring special machinery to make a limited edition of a set of chairs.

Total direct costs are collectively known as Prime Costs and we can see that Product Costs are the sum of Prime costs and Overheads.

Indirect Costs: Indirect costs are those costs that are incurred in the factory but that cannot be directly associate with manufacture. Again these costs are classified according to the three elements of cost, materials labour and overheads.

• Indirect materials: Some costs that we have included as direct materials would be included here.
• Indirect labour: Labour costs of people who are only indirectly associated with manufacture: management of a department or area, supervisors, cleaners, maintenance and repair technicians
• Indirect expenses: The list in this section could be infinitely long if we were to try to include every possible indirect cost. Essentially, if a cost is a factory cost and it has not been included in any of the other sections, it has to be an indirect expense. Here are some examples include:
Depreciation of equipment, machinery, vehicles, buildings
Electricity, water, telephone, rent, Council Tax, insurance
Total indirect costs are collectively known as Overheads.

Finally, within Product Costs, we have Conversion Costs: these are the costs incurred in the factory that are incurred in the conversion of materials into finished goods.

The classification of Period Costs:

The scheme shows five sub classifications for Period Costs. When we look at different organisations, we find that they have period costs that might have sub classifications with entirely different names. Unfortunately, this is the nature of the classification of period costs; it can vary so much according to the organisation, the industry and so on. Nevertheless, such a scheme is useful in that it gives us the basic ideas to work on.

Administration Costs: Literally the costs of running the administrative aspects of an organisation. Administration costs will include salaries, rent, Council Tax, electricity, water, telephone, depreciation, a potentially infinitely long list. Notice that there are costs here such as rent, Council Tax, that appear in several sub classifications; in such cases, it should be clear that we are paying rent on buildings, for example, that we use for manufacturing and storage and administration and each area of the business must pay for its share of the total cost under review.

Without wishing to overly extend this listing now, we can conclude this discussion by saying that the costs of Selling, the costs of Distribution and the costs of Research are all accumulated in a similar way to the way in which Administration Costs are accumulated. Consequently, our task is to look at the selling process and classify the costs of running that process accordingly: advertising, market research, salaries, bonuses, electricity, and so on. The same applies to all other classifications of period costs that we might use.

Finance Costs: Finance costs are those costs associated with providing the permanent, long term and short term finance. That is, within the section headed finance costs we will find dividends, interest on long term loans and interest on short term loans.

Finally, we should say that we can add any number of subclassifications to our scheme if we need to do that to clarify the ways in which our organisation operates. We will also add further subclassifications if we need to refine and further refine out cost analysis.

MATERIAL

1) Reorder level = Maximum usage * Maximum lead time
(Or) Minimum level + (Average usage * Average Lead time)

2) Minimum level = Reorder level – (Average usage * Average lead time)

3) Maximum level = Reorder level + Reorder quantity – (Minimum usage *
Minimum lead time)

4) Average level = Minimum level +Maximum level (or)
2
Minimum level + ½ Reorder quantity

5) Danger level (or) safety stock level
=Minimum usage * Minimum lead time (preferred)
(or) Average usage * Average lead time
(or) Average usage * Lead time for emergency purposes

6) EOQ (Economic Order Quantity - Wilson’s Formula) = √2AO/C
Where A = Annual usage units
O = Ordering cost per unit
C = Annual carrying cost of one unit
i.e. Carrying cast % * Carrying cost of unit

7) Associated cost = Buying cost pa + Carrying cost pa

8) Under EOQ Buying cost = Carrying cost

9) Carrying Cost = Average inventory * Carrying cost per unit pa * Carrying cost %
(Or) Average Inventory * Carrying cost per order pa

10) Average inventory = EOQ/2

11) Buying cost = Number of Orders * ordering cost

12) Number of Orders = Annual Demand / EOQ

13) Inventory Turnover (T.O) Ratio = Material consumed
Average Inventory

14) Inventory T.O Period = 365 .
Inventory Turn over Ratio
15) safety stock = Annual Demand *(Maximum lead time - Average lead time)
365
16) Total Inventory cost = Ordering cost + Carrying cost of inventory +Purchase cost

17) Input Output Ratio = Quantity of input of material to production
Standard material content of actual output

Remarks :-

1) High Inventory T.O Ratio indicates that the material in the question is fast moving

2) Low Inventory T.O Ratio indicates over investment and locking up of working
Capital in inventories

Pricing of material Issues:-

1) Cost price method:-
a) Specific price method
b) First in First Out method (FIFO)
c) Last in First Out method (LIFO)
d) Base stock method

2) Average price method:-

a) Simple average price method = Total unit price
Total No. of purchases

b) Weighted average price method = Total cost
Total No. of units

c) Periodic simple average price method = Total unit price of certain period
Total Number of purchases of that period (This rate is used for all issues for that period. Period means a month (or) week (or) year)

d) Periodic weighted average price method = Total cost of certain period
Total Number of units of that period
e) Moving simple average price method
= Total of periodic simple average of certain number of periods
Number of periods



f) Moving weighted average price method
= Total of periodic weighted average of certain number of periods
Number of periods

3) Market price method:-

a) Replacement price method = Issues are valued as if it was purchased now at
current market price
b) Realizable price method = Issues are valued at price if it is sold now

4) Notional price method:-

a) Standard price method = Materials are priced at pre determined rate (or)
Standard rate

b) Inflated price method = The issue price is inflated to cover the losses incurred
due to natural(or)climatic losses

5) Re use price method = When materials are returned (or) rejected it is valued at
different price. There is no final procedure for this method.

ABC Analysis (or) Pareto Analysis :- In this materials are categorized into

Particulars Quantity Value
“A” – Important material 10% 70%
“B” – Neither important nor unimportant 20% 20%
“C” – UN Important 70% 10%

Note:-

1) Material received as replacement from supplier is treated as fresh supply

2) If any material is returned from Department after issue, it has to be first
disposed in the next issue of material

3) loss in the book balance of stock and actual is to be transferred to Inventory
adjustment a/c and from there if the loss is normal it is transferred to Over Head
control a/c. If it is abnormal it is transferred to costing profit and loss a/c.

4) CIF = Cost Insurance and Freight (This consignment is inclusive of prepaid
insurance and freight)


5) FOB = Free on Board (Materials moving by sea – insurance premium is not
paid)

6) FOR = Free on Rail (Insurance and freight is not borne by the supplier but paid
by the company or purchase)

7) For each receipt of goods = Goods Receipt note

8) For each issue of goods = Materials Requisition note (or) Material Issue note

Accounting Treatment :-

1) Normal Wastage = It should be distributed over goods output increasing per unit
cost

2) Abnormal Wastage= It will be charged to costing profit and loss a/c

3) Sale value of scrap is credited to costing profit and loss a/c as an abnormal gain.

4) Sale proceeds of the scrap can be deducted from material cost or factory
overheads.

5) Sale proceeds of scrap may be credited to particular job.

6) Normal Defectives = cost of rectification of defectives should be charged to
specific

7) Abnormal Defectives = This should be charged to costing profit and loss a/c

8) Cost of Normal spoilage is to borne by good units

9) Abnormal spoilage should be charged to costing profit and loss a/c











LABOUR

Method of Remuneration:

1) Time Rate system
a) Flat time Rate
b) High wage system
c) Graduated time rate

2) Payment by Results

a) Piece rate system
i) Straight piece rate
ii) Differential piece rate
• Taylor system
• Merrick system

b) Group Bonus System
i) Budgeted Expenses
ii) Towne gain sharing scheme
iii) Cost efficiency bonus
iv) Priest man system

c) Combination of Time and Piece rate

iii) Rowan scheme
iv) Barth scheme
v) Accelerating premium bonus scheme

e) Other incentive schemes
i) Indirect monetary incentive
• Profit sharing
• Co-partnership
ii) Non-Monetary Incentive

1) Time rate system = Hours worked * Rate per hour (Basic wages)

2) Piece rate system:

i) Straight piece rate earnings = Number of units produced * Rate per unit

ii) Differential Piece rate

a) F.W.Taylor’s differential rate system
» 83% of piece rate when below standard
» 125% of piece rate when above or at standard

b) Merrick differential or multiple piece rate system

Efficiency level Piece rate
» up to 83% »Normal piece rate
» 83% to 100% » 110% of Normal rate
» Above 100% » 120% of Normal rate

iii) Gantt Task and Bonus system

Output Payment
» Below standard » Time rate (guaranteed)
» At standard » 20% Bonus of Time rate
» Above standard » 120% of ordinary piece rate

iv) Emerson’s Efficiency system

Efficiency Payment
» Below 66.7% » Hourly Rate
» from 66.7% » Hourly rate (+) increasing bonus according to degree
to 100% of efficiency on the basis of step bonus rates
» Above 100% » Hourly rate (+) 20% Bonus (+) additional bonus of 1%
of hourly rate for every 1% increase in efficiency

v) Halsey Premium Plan = Basic wages + 50% of time saved * Hourly Rate

vi) Halsey Weir Premium Plan = Basic wages + 30% of time saved * Hourly rate

vii) Rowan Plan = Basic wages + Time saved * Basic Wages Time allowed

viii) Bedaus Point system = Basic wages + 75% * Bedaus point/60 * Rate/hr
ix) Barth’s System = Hourly rate * √Std time *Time taken

Labour Turnover:-

1) Separation rate method = Separation during the period
Average No. of worker’s during the period

2) Net labour T.O rate (or) Replacement method
= Number of replacements
Average No. of worker’s during the period

3) Labour flux rate = No. of separation + No. of replacement
Average No. of worker’s during the period

Accounting Treatment

1) Normal Idle time = Charged to factory overheads

2) Normal but un-controllable = It should be charged to job by inflating wage rate.

3) Abnormal = It should be charged to costing P & L a/c






















OVER HEADS

Reapportionment of service department expenses over production department :-

1) Direct redistribution method:
• Service department costs are divided over production department.
• Ignore service rended by one dept. to another

2) Step method of secondary distribution (or) Non reciprocal method:
• Service department which serves largest number of service department is divided first and go on.

3) Reciprocal service method:

i) Simultaneous equation method (or) Algebraic method
• Equation is formed between service departments and is solved to find the amount due.

ii) Repeated distribution method:
• Service department cost separated repeatedly till figure of service dept. is exhausted or too small.

iii) Trial and Error method:
• Cost of service department is apportioned among them repeatedly till the amount is negligible and the total is divided among production department.

Treatment of Over/Under absorption of overheads:-

i) If under absorbed and over absorbed overheads are of small value then it should be
transferred to costing profit and loss a/c

ii) If under and over absorption occurs due to wrong estimates then cost of product
manufactured should be adjusted accordingly.

iii) If the same accrued due to same abnormal reasons the same should be transferred
to costing profit & loss a/c

Apportionment of overhead expenses – Basis

a) Stores service expenses = Value of materials consumed

b) Factory rent = Floor area

c) Municipal rent, rates and taxes = floor area

d) Insurance on Building and machinery = Insurable value

e) Welfare department expenses

f) Supervision

Number of employees
g) Amenities to employee’s

h) Employees liability for insurance

j) Lighting power = Plug point

k) Stores over heads = Direct material

l) General over heads = Direct wages

Reapportionment of service department cost to production department :-

1) Maintenance dept. = Hours worked for each dept.

2) Pay roll and time keeping = Total labour (or) machine hours (or) Number of
employees in each department

3) Employment (or) Personnel department = Rate of labour T.O (or) No. of
employees of each department

4) Stores Keeping department = No. of requisitions (or) value of materials of each
department

5) Purchase department = No. of purchase orders value of materials of each
department

6) Welfare, ambulance, canteen, service, recreation room expenses
= No. of employees in each department.

7) Building service department = Relative area each dept.

8) Internal transport service (or) overhead crane service
= weight, value graded product handled, weight and distance traveled.


9) Transport department = Crane hours, truck hours, truck mileage,
Number of packages.

10) Power house (electric power cost) = Housing power, horse power machine hours,
No. of electric points etc.

11) Power house = Floor area, cubic content.




































RECONCILATION OF COST AND FINANCIAL A/C

Causes of differences:-

1) Purely financial items :
i) Appropriation of profits ►Transferred to reserves, goodwill, preliminary
expenses, dividend paid etc.
ii) Loss on sale of investment, penalties and fines
iii) Income ► Interest received on Bank deposits, profit on sale of investments,
fixed assets, transfer fees.

2) Purely cost account items: - Notional Rent / Interest / Salary

3) Valuation of stock:-

i) Raw-material = In financial a/c’s stock is valued at cost or market value
Whichever is less, while in cost a/c’s it is valued at LIFO, FIFO etc.

ii) Work in progress = In financial a/c’s administrative expenses are also
considered while valuing stock, but in cost a/c’s it may be
valued at prime (or) factory cost (or) cost of production

iii) Finished Goods = In financial a/c’s it is valued at cost or market price
whichever is less, in cost a/c’s it is valued at total cost of production.

4) Overheads: In financial = Actual expenses are taken
In cost = Expenses are taken at predetermined rate.

5) Depreciation: In financial = Charged in diminishing or fixed balance method
In cost = Charged in machine hour rate

6) Abnormal Gains: In financial = Taken to profit & Loss a/c
In cost = Excluded to cost a/c’s or charged in costing
profit & Loss a/c
