Part A
What is a cost sheet?
A cost sheet
is a statement for arriving at the cost of production and cost of sales of a
product, job, operation or work order. It can be prepared at regular intervals
− monthly, quarterly or yearly − the regular interval being known as cost period. The cost sheet presents the
total as well as per unit cost of products manufactured during the cost period.
From cost sheet costing profit can also be calculated by deducting cost of
sales from total sale price.
Cost sheets
may be prepared on the basis of actual data (e.g. actual expenses, actual
output, actual sales, etc.) or on the basis of estimated data (e.g. estimated
expenses, estimated output, estimated sales, etc.). It is necessary to make
estimation of costs for the purpose of submitting tenders or quotations for a
prospective supply order, job or work order.
Uses of cost sheet
1.
It
helps in fixing the sale price per unit of a product or sale price of a job or
work order.
2.
It
facilitates comparison of costs of similar products, jobs or work order as well
as comparison of costs incurred in different periods.
3.
It
provides information for estimating cost and sale price of a product, job or
work order for the purpose of submitting tenders or quotations.
4.
It
helps in identifying operational inefficiencies and measures for controlling
wastes and losses due to unproductive uses of men, machines and materials.
5.
It
helps in formulating an efficient as well as effective production policy.

Important points on preparation of cost sheet:
1.
Per-unit
costs will be calculated by dividing the total amount by number of units
produced up to cost of production per unit, after that per-unit costs as well
as per-unit profit and per-unit sales will be calculated by dividing the total
amount by number of units sold.
2.
Donations
(not an element of cost), cash discount allowed (a finance cost), interest paid
or payable (a finance cost), dividend paid or payable (an appropriation of
profit), income tax (an appropriation of profit) are always to be excluded from
cost sheet.
3.
Bank
charges (charges made by the bank for handling the account and for rendering
other financial services) are always to be regarded as an item of
administration overhead.
Items Excluded from Cost Accounts
There are certain items which are included in
financial accounts of a manufacturing concern but shall not to be included in
cost accounts since they are not related to cost of production. These items
fall into three categories:-
1.
Appropriation of profits:
i.
Appropriation to sinking funds
ii.
Dividends paid
iii.
Taxes on income and profits
iv.
Transfers to general reserves
v.
Provision for bad debts
vi.
Amount written off – goodwill, preliminary expenses,
underwriting commission, discount on debentures issued; expenses of capital
issue etc.
vii.
Capital expenditures specifically charged to revenue
viii.
Charitable donation
2. Matters of pure finance:
(a) Purely financial charges:-
i.
Losses on sale of investments, buildings, etc.
ii.
Expenses on transfer of company’s office
iii.
Interest on bank loan, debentures, mortgages, etc.
iv.
Damages payable
v.
Penalties and fines
vi.
Losses due to scrapping of machinery
vii.
Remuneration paid to the proprietor in excess of a
fair reward for services rendered
(b) Purely financial incomes:-
i.
Interest received on bank deposits
ii. Profits made on the sale of investments,
fixed assets, etc.
iii. Transfer fees received
iv. Rent receivable
v. Interest, dividends, etc. received on
investments.
vi. Brokerage received
viii.
Discount, commission received
3. Abnormal gains and losses:
i.
Losses or gains on sale of fixed assets.
ii.
Loss to business property on account of theft, fire or
other natural calamities.
Estimated cost sheet
Estimated
cost sheets are usually prepared for estimating the price at which the products
are expected to be sold. More specifically, estimated cost sheets are prepared
with the objective of calculating the estimated costs for the following
purposes:
1.
Determining
the prices to be quoted against any offer for sale;
2.
Preparing
different functional budgets for the next accounting period;
3.
Identifying
actions to be taken now to reap benefit from any expected opportunities in the
future market for goods and services used in the manufacture as inputs;
4.
Identifying
actions to be taken now to be able to deal with any expected threats in the
future market for goods and services used in the manufacture as inputs; and
5.
Making
out an effective plan for production and sale to be carried out in the next
accounting period.
When
any offer for sale is received from any domestic or foreign customer, price has
to be quoted keeping under consideration the expected changes in prices of
inputs (such as material, labour and different overheads) which may come up in
course of production for the order to be executed. But the basis for all such
calculations should be the actual costs already incurred during the previous
year or current year, as the case may be.
Overhead
recovery rates for estimating the total cost should be based on revised cost
sheet for the previous or current year, as the case may be, the revision in the
cost sheet being carried out for the changes in input price.
Therefore,
steps for preparing the estimated cost sheet may be given as follows:
STEP – 1:
Prepare
actual cost sheet for actual production for
the current year or previous year, as the case may be, on the basis of records
of actual production.
STEP – 2:
Prepare
revised cost sheet for actual production
on the basis of expected changes in prices of inputs. (Skip this step if there
is no price change expected).
STEP – 3:
On
the basis of revised cost sheet (or actual cost sheet, as the
case may be) establish the different recovery rates. For example:
(a)
Factory
overhead recovery rate on the basis of direct wages;
(b)
Administrative
overhead recovery rate on the basis of works cost;
(c)
Selling
and distribution overhead recovery rate on the basis of cost of goods sold.
STEP – 4:
Prepare estimated cost
sheet for estimated/required production with changed prices and
the recovery rates as established in STEP – 3 above.
Re: Bad Debts
According to some accountants bad
debts are financial losses and thus excluded from cost accounts. If, however,
bad debts are included in cost, it should be treated as selling overhead and
may be apportioned to various products on the basis of the credit sales of
products. Abnormal amounts of bad debts, which are of exceptional nature,
should be included in cost accounts.
ICMAI
MTP QUESTION
State the treatment of Bad Debts in Cost record.
ICMAI ANSWER
We know bad debt refer to customers who do not pay money after having purchased the product. This situation arises after the sale is done. Many experts say that bad debt is not an item of expense but it’s a financial loss and thus should be excluded for the purpose of costing. However normal bad debts may be considered as selling expense and included in the cost. An exceptional case like bankruptcy of a big institution may be excluded from the cost.

A brain scan
is normally carried out on machine type XR1; this task uses special X-Ray
Plates costing Rs 40 each and takes 4 hours of machine time. Because of the
nature of the process, around 10% of the scans produce blurred and therefore
useless results.
Required:
a)
Calculate
the cost of a satisfactory brain scan on machine type XR1;
b)
Brain
scans can also be done on machine type XR50 and would take only 1.8 hours per
scan with a reduced rejection rate of 6%. However, the cost of X-Ray Plates
would be Rs 55 per scan.
Advice which type of X-Ray machine should be used, assuming sufficient capacity is available on both types of machine.
