Costing enables the managers of a business to know the
cost of the firms output. Once costing information is
available, managers can use it to help with decision making,
planning and control of expenditure.
Cost accounting is widely used by:
A manufacturing business
A business that provides a service.
By being able to work out the cost of a
product/service, the managers of an
organisation can then use this cost to:
Determine a selling price.
Value inventory.
Provide information for financial statements.
Make management decisions.
What is a costing system
A costing system is used by an organisation to collect
information about costs and use that information for
decision making, planning and control.
Financial accounting and management accounting
Financial accoutning
Financial accoutning is concerned with
recording financial transactions that have
happened already, and with providing
information from the accounting statements.
The main features of financial accounting are that it:

Accurate to the nearest
penny.
Legal requirement.

at actul transactions in different ways from
financial accounting. In this way, management
accounting is able to provide information to help
the business or organisation plan for the future.
The main features of management accounting are that it:
Makes estimates for the future.
Looks in detail at the costs and the sales income.
Provides management with reports.
Used internally within the business.

Introduction to classifying costs and income
The elements of cost
Materials
Raw materials
Products bought for resale
Service items/consumables
Labour
Wages
Salaries
Public sector wages
Expenses
All other running costs of the business
Classification of costs by function and nature.
The costs incurred in the factory are production costs
Direct costs
Costs that cannot be linked
directly with each unit of
output.
Direct materials
The cost of the materials used to make the items produced
Direct labour
The cost of paying the employees who carry out the production
Direcxt expenses
Indirect costs
Costs that can be directly
linked with each unit of
output.
Indirect materials
The cost of materials that cannot be
directly linked to specific items produced.
Indirect labour
The cost of employing people
in the factory who do not
actually make the products.
Indirect expenses
The other costs of running a factory
Chapter 2: Cost centres and overhead absorption
Cost centres
Cost centres are sections of an
organisation to which costs can
be charged.
Profit centres
Profit centres are sections of
a business to which costs can
be charged, income can be
identified and profit can be
calculated.
Investment centres
A section of a business to which costs
can be charged, income can be identified
and investment can be measured.
Coding systems
Numeric coding
Alphabetic coding
Alpha-numeric coding
Units of output method
Budgeted overheads / Budgeted units of output
Direct labour hours method
Budgeted overheads/ Budgeted direct labour hours
Machine hours method
Budgeted overheads / Budgeted machine hours
Chapter 3: Cost behavior
The way in which costs alter
with changes in the level of
output or activity.
There are three main ways in which costs may behave:
Fixed Costs
Fixed costs do not alter when the
level of output or activity changes.
Variable Costs
Variable costs change in proportion to
the level of output or activity.
Semi-variable costs
Semi-variable costs contain both a fixed
element and a variable element.
Total costs:
Variable costs per unit X Output + Fixed
costs
Unit costs:
Fixed costs / Output + Variable costs per unit
Chapter 4: Inventory valuation and the
manufacturing account
Types of inventory:
Raw materials
These are the
materials that have
been bought by a
manufacturing
business and are
ready to be
transferred to the
production area
where they will be
used to make the
finished goods.
Work-in-progress
This comprises part
finished products that
are awaiting
completion
Finished goods
These are manufactured
items that have been
completed and are
ready for sale
Valuation methods:
FIFO
A method of
inventory valuation
that assumes that
goods will be used
up in the order that
they are acquired.
This means that the
remaining balance will
be valued based on
the prices of more
recent purchases.
LIFO
This method of
inventory valuation
assumes that the
most recently
acquired inventory will
be used first, leaving
the earlier
acquisitions to make
up the value of the
remaining balance.
This does not have to
correspond with the
actual order of
usage.
AVCO
This inventory
valuation method
involves calculating
a new weighted
average cost of
goods each time
that a new
purchase is made,
and using this
valuation for
subsequent issues
and balances until
further purchases
are made.
Manufacturing account format:
Opening inventory of raw
materials
Purchases of raw materials
Closing inventory of raw materials
Direct materials used
Opening inventory of raw materials +
Purchases of raw materials - Closing
inventory of raw materials
Direct labour
Direct cost
Direct materials used + Direct cost
Manufacturing overheads
Manufacturing cost
Direct cost + Manufacturing overheads
Opening inventory of work in progress
Closing inventory of work in progress
Cost of goods manufactured
Manufacturing cost +
Opening inventory of work
in progress - Closing
inventory of work in
progress
Opening inventory of finished goods
Closing inventory of finished goods
Costs of goods sold
Cost of goods manufactured +
Opening inventory of finished goods -
Closing inventory of finished goods
Chapter 5: Labour costs
Time rate
Time rate is based on
payment for the amount
of time spent working.
Overtime
An overtime rate is a time rate
that is paid for time worked in
excess of the normal contracted
time.
Bonus payments
A bonus payment is an extra
payment paid to employees as
a reward for productivity.
Piecework
Piecework is payment based on
the number of items produced by
the employee.
Chapter 6: Budgets and variances
Budgets
A budget is a financial plan for an organisation that is prepared in advance.
What is the purpose of a budget?
Creates plans
Co ordinates plans
used to monitor and control
Variances
The difference between the
budgeted figure and the actual figure.
Variances can either be:
Adverse
Where the actual cost is greater than the budgeted cost
Favourable
Where the actual cost is less than the budgeted cost
