Management Accounting Flashcards
Cost unit (definition)
a measurement of output, e.g., a ton of steel, a litre of paint, a kg of sugar.
Cost centre (definition)
a part of the business for which a measurement of cost is required.
What is the difference between direct costs and indirect costs?
Direct costs
- can be specifically and exclusively identified with a given cost object.
Indirect costs
- cannot be specifically and exclusively identified with a given cost object.
- are assigned to cost objects on the basis of cost allocations.
Cost allocation (definition)
- the process of assigning costs to cost objects that involve the use of surrogate, rather than direct measures.
The distinction between direct and indirect costs depends on …?
The distinction between direct and indirect costs depends on what is identified as the cost object.
Product costs (definition)
those that are identified with products and included in the stock (inventory) valuation
Cost object (definition)
any activity for which a separate measurement of cost is required (e.g. cost of making a product or providing a service)
Period costs (definition)
Not?
Treated as?
- not specifically related to the product and are not included in the inventory valuation.
- They are treated as expenses in the period in which they are incurred
Figure 2.2 - Treatment of period and product costs
- Manufacturing cost is a product cost
- Non-manufacturing costs are period costs
When a product cost is unsold it is recorded as an asset in the balance sheet but becomes an expense when the product is sold in the profit and loss account
A period cost is recorded as an expense in the profit and loss account in the current accounting period
Why is cost behaviour important?
- to predict costs and revenues at different activity levels for many decisions.
Variable costs (definition)
Costs that vary in direct proportion with activity.
Fixed costs (definition)
Costs that remain constant over wide range of activity
Semi-fixed costs (definition)
Costs that are fixed within specified activity levels, but they eventually increase or decrease by some constant amount at critical activity levels
Semi-variable costs (definition)
Costs that include both a fixed and a variable component (e.g. telephone charges)
Variables Costs diagrams
Fixed Costs diagrams
Step-fixed costs diagram
Sunk costs (definition)
Opportunity costs (definition)
Incremental cost (definition)
Marginal costs (definition)
Sunk costs
- costs that have been incurred and cannot be changed by any decision in the future
Opportunity costs
- Costs that measure the opportunity that is sacrificed when the choice of one course of action requires that an alternative course of action is given up
Incremental cost
- the difference between costs of alternative courses of action
Marginal costs
- the cost of one extra unit of output
A cost and management accounting system should generate information for meeting the following requirements: (4)
- Inventory valuation for internal and external profit measurement.
- Provide relevant information to help managers make better decisions.
- Provide information for planning, control, and performance measurement.
A database should be maintained, with costs appropriately coded and classified so that relevant information can be extracted to meet each of the above requirements.
There are three main costs that businesses incur:
- Materials
- Labour
- Expenses
Correctly identifying these, working out the right amount of cost and treating them correctly is critical for all
businesses
There are two reasons why knowing the cost of inventory is vital:
- Value of goods ‘issued’
- Value of goods held
Material costs – valuation
- Actual cost
- The First In First out method FIFO (what is it?)
- The Last in First out method LIFO (what is it?)
- The Weighted Average Cost method WAS (what is it?)
FIFO:
- assumes that the oldest items are used first, so that inventory is VALUED at the most recent prices
LIFO:
- assumes that the latest items are used first, so that inventory is valued at the oldest prices
- (this method is not allowed by IAS Inventories 2)
WAS:
- assumes no pattern of the order in which items are used, so all are VALUED at the same value, which is the average one.
Labour costs
This can be one of the most expensive elements within the cost of unit, especially for service industries.
Labour costs can be worked out per hour or per unit – read the question carefully.
For example, a question could state that each unit has a labour cost of £20. Or, the question could state that each unit takes 2 hours to make and labour costs are £10 per hour
What factors can affect labour costs? (5)
- Wages rates paid by other businesses
- National / living wages imposed by Government
- Government incentives
- Local employment conditions – availability of unskilled and / or skilled workforce
- Employer costs above gross salaries (about 20%)
What is the difference between relevant/avoidable costs & revenues and irrelevant/unavoidable costs & revenues
Relevant/ Avoidable costs and revenues:
- are changed by a future decision
Irrelevant/ unavoidable costs and revenues:
- are not changed by a future decision
Costs incurred in a manufacturing business diagram
Prime cost (definition)
the direct cost of a commodity in terms of the materials and labour involved in its production, excluding fixed costs
Eg. Direct materials + Direct labour = Prime cost
Examples of production overheads (5) and non-production overheads (3)?
Production overheads:
- Rent and rates
- Factory power
- Factory heat and light
- Factory expenses
- Depreciation of plant
Non-production overheads:
- Selling and distribution
- Advertising
- Admin expenses (salaries of office staff and office expenses)
Features of manufacturing, merchandising and service organisations
What type of materials are held by businesses will depend on the type of business
Manufacturing:
- Raw materials
- Work in progress
- Finished goods
Merchandising/retail:
- Tangible products for resale i.e. finished goods inventory
Service organisations:
- Provide a service that cannot be stored, but may have work in progress
A cost collection system normally accounts for costs in two broad stages:
- Accumulates costs by classifying them into certain categories (e.g. labour, materials and
overheads); - Assigns costs to cost objects.

Graph of fixed and variable costs
Separating Fixed and Variable costs
It is important to be able to identify the amount of fixed and variable costs. Sometimes the information is given to you but sometimes it is not.
Where total costs are known for two levels of output, the amounts of fixed and variable costs can be worked out using the ‘high/low’ method
Separating Fixed and Variable costs
Where total costs are known for two levels of output, the amounts of fixed and variable costs can be worked out using the ‘high/low’ method.
Example of High / Low method:
- At output of 1,000 units, total costs are £7,000
- At output of 2,000 units, total costs are £9,000.
What are the fixed costs?
What is the variable cost per unit?
(Note that this only works when the variable cost per unit is constant)
Variable cost per unit - £2000/1000 = £2.00
For 1,000 units:
Total cost = £7,000
Variable cost = 1,000 x £2 = 2,000
Fixed cost = 5,000
Costing systems
Going to consider the situation in manufacturing where the cost
object is a product
What are the 2 types of costing systems?
Job-order costing:
- Assume that there are individual products or batches of products
- The products or batches incur different costs so that there is a need to keep track of each product or batch
Process-order costing:
- Used in industries where masses of the same product are produced in a flow process
Cost assignment methods
What happens to direct costs vs indirect costs?
- Direct costs - Direct tracing to - Cost Objects
- Indirect costs - go under cost allocations to either: - cause and effect allocations (the more we purchase, the more the cost will increase) or - arbitrary allocations (like direct labour hours or machine hours)
Overhead absorption
The number of units produced can be used to work out the
overhead per unit.
But this only works if there are static units produced which
are uniform.
In most manufacturing environments, that is not the case, so
another way to allocate overheads is either: (2)
- Firstly, the overhead absorption rate (OAR) needs to be
found. - Then this can be applied to the units.
Arbitrary Allocations
- Based on direct labour hours or
- Based on machine hours
OAR – Plant wide rate/blanket overhead rate
This is the ___________ of all methods and applies overheads direct to a production department.
This method is only valid for more _______ businesses who do not
have _________ departments or _________ ________.
What are advantages (2) and disadvantages (3) of this method?
This is the simplest of all methods and applies overheads direct to a production department.
This method is only valid for more simple businesses who do not
have complex departments or multiple products.
Advantages:
- Simple to calculate,
- low cost to implement
Disadvantages:
- Arbitrary,
- simplistic,
- inaccurate
OAR – 2 stage allocation process
This is a more complex method of allocating overheads.
Applies to both traditional methods and ABC systems
Traditional costing system: (4)
Stage 1
- Assign all manufacturing overheads to production and
service centres - Reallocate the costs assigned to service cost centres to
production centres
Stage 2
- Compute separate overhead rates for each production
cost centre - Assign cost centre overheads to cost objects
What might be used as cost centres in a traditional costing system?
What might be used as an activity cost centre in an activity-based costing system?
What might be used as cost centres in a traditional costing system?
- Mattress line – border added
- Building section – where fillings are added, may include tufting and tape edging.
- Delivery
What might be used as an activity cost centre in an activity-based costing system?
- Steel frame
- Adding border, hand stitching
- Building bed – adding fillings
- Tufting
- Tape Edging
OAR – ABC (Activity Based Costing)
This is a much more complex method of allocating overheads.
It identifies activities within a business and assigns costs based on those activities. (3)
Stage 1
- Activities are divided into activity cost centres.
- The total cost associated with each activity is allocated to
the relevant activity cost centre.
Stage 2
- The total cost in each cost centre is then charged to output using a cost driver.
Methods of costing (2)
- Direct costing = Direct cost tracing only assigns direct manufacturing costs, not fixed manufacturing costs, to products or services
- Overhead absorption costing = involves allocating production overheads to
cost objects:- Plant wide / Blanket Overhead Absorption Rate – OAR based on machine hours and labour hours – different overhead allocation to the 2 jobs. - 2 – stage allocation process for both traditional absorption costing systems and Activity Based Costing systems
Under or Over Absorption of overheads in absorption costing
What is the issue? (3)
- The OAR is based on budgeted overheads and budgeted activity e.g. number of labour hours.
- At the end of the period, we know what the actual activity was and apply the OAR to the actual activity.
- The difference between the absorbed overheads and the actual overheads is a period cost adjustment in the financial accounts. The period may be a month, quarter, or year for example.
OAR Issues: Budgeted Overheads
There are problems in using actual overheads:
There is a delay in finding product costs, so essential information for decision making is not available until the end of the accounting period
- Monthly profit calculations
- Inventory valuation
- Basis for setting prices
- If this is done monthly, then fluctuations in OAR will occur
Seasonality – changes in activity, customers want to know the price
- Need to use an estimated normal product cost based on average long-run activity rather than an actual product cost
- Establish a budgeted overhead rate based on annual estimated overhead expenditure and activity
Under and over recovery of
overheads
It is very unlikely that the actual overheads and / or production levels are the same as the budgeted overheads and production levels used to calculate the OAR
Therefore, overheads will be under or over recovered
- Under or over recovery of overhead due to the activity level being different to the budgeted activity level is called a ______ ___________ __________ ____________
- Under or over recovery of overhead due to the actual fixed overhead expenditure being different to the budget is called a _______ __________ _______________ __________
- Financial accounting regulations require that under or over recovery of overheads is treated as a ______ _____ ____________
It is very unlikely that the actual overheads and / or production levels are the same as the budgeted overheads and production levels used to calculate the OAR
Therefore, overheads will be under or over recovered
- Under or over recovery of overhead due to the activity level being different to the budgeted activity level is called a FIXED OVERHEAD VOLUME VARIANCE
- Under or over recovery of overhead due to the actual fixed overhead expenditure being different to the budget is called a FIXED OVERHEAD EXPENDITURE VARIANCE
- Financial accounting regulations require that under or over recovery of overheads is treated as a period cost adjustment
Non-Manufacturing overheads
Financial accounting regulations specify that only ____________ ________ should be allocated to products.
Non-manufacturing costs should be assigned to products for __________-_________ (particularly cost-plus pricing).
Some non-manufacturing costs may be a ________ _____, of the product
Examples: (3)
Generally, aim to select an allocation base/_____ ______ that corresponds to the ___________ of non-manufacturing overhead
For many non-manufacturing overheads, it may be hard to determine an appropriate basis for allocation. A widely used approach is to allocate based on the product’s production costs
Financial accounting regulations specify that only manufacturing overheads should be allocated to products.
Non-manufacturing costs should be assigned to products for decision-making (particularly cost-plus pricing).
Some non-manufacturing costs may be a direct cost, of the product
Examples:
- Delivery costs,
- Sales commission,
- Travel costs
Generally, aim to select an allocation base/cost driver that corresponds to the causation of non-manufacturing overhead
For many non-manufacturing overheads, it may be hard to determine an appropriate basis for allocation. A widely used approach is to allocate based on the product’s production costs
Aims of costing
One of the main aims of costing is to establish the cost of one cost unit of work, whatever the work is.
Examples of a cost unit could be:
- Manufacturing: per item made
- Chemical business: kilogram of chemical
- Transport company: passenger mile
- Nursing home: resident day
- University: student
Methods of costing – job costing
- Job costing is used where each job can be separately identified from other jobs and costs are charged to that specific job.
- All direct costs are easy to identify, and the overheads are added on a predetermined basis, such as labour hours or machine hours.
- The overheads are allocated on a predetermined OAR basis.
Methods of costing – continuous work – Process Costing
- Used where masses of similar products or services are produced in a flow process.
- In the manufacturing industry, this could be making food. In this case, process costing is the method used.
- In this situation, the total costs of the process for a given period of time are collected together and averaged per unit of output for that period.
Marginal and absorption costing
These two costing systems are often used in cost accounting, but for different purposes:
Marginal (variable) costing – ?
Absorption costing – ?
The use of each system is dependent on the informational needs of the business:
- ‘can we afford to sell 1,000 units of our product at a discount of 20%?’ – this is _________ costing
- ‘what profit have we made this year?’ – __________ costing
Marginal and absorption costing
These two costing systems are often used in cost accounting, but for different purposes:
- Marginal (variable) costing – helps with short-term decision making.
- Absorption costing – is used to calculate inventory valuations and profit calculations.
The use of each system is dependent on the informational needs of the business:
- ‘can we afford to sell 1,000 units of our product at a discount of 20%?’ – this is marginal costing
- ‘what profit have we made this year?’ – absorption costing
Marginal costing (Variable Costing)
What is marginal costing?
What are costs classified by and what is the effect of this?
What is the marginal cost of a unit usually but not always?
What does knowing this cost allow?
The contribution is:…?
Marginal costing is effectively the cost of producing one extra unit of output.
Cost are classified by their behaviour (variable, fixed) so that it is easy to work out the cost of producing one extra unit.
The marginal cost of a unit is usually (but not always) the total of the variable costs of producing a unit of output.
Knowing this cost allows managers to consider the contribution to the business by each unit.
The contribution is: selling price less variable cost.

Marginal costing – Contribution
- Once the contribution per unit has been established, the total contribution for the period can be established.
- The fixed costs are then ___________ , to arrive at the _________ for the period.
- Once the contribution per unit has been established, the total contribution for the period can be established.
- The fixed costs are then deducted, to arrive at the profit for the period.
Advantages to a marginal costing statement (4,5)
- Contribution per unit is clearly identified
- Effect on changes to costs easily identified
- Effect on changes to selling price easily identified
- Helps with short-term decision making such as:
- Break even analysis - Margin of safety - Target profit - Contribution sales ratio - Limiting factors
Absorption costing
This method answers the question … ‘What does it cost to make one unit of output?’
The absorption cost of a unit of output is made up of:
This method answers the question … ‘What does it cost to make one unit of output?’
- Direct materials
- Direct labour
- Direct expenses
- Production overheads (variable and fixed)
- Absorption cost

Marginal and absorption costing
What do they treat differently and what is the effect of this therefore?
Why is this because?
What does IAS 2 Inventories do?
What does absorption costing have to be used for?
Marginal and absorption costing treat fixed overheads differently; therefore, the two methods will produce different levels of profit when there is closing inventory.
This is because:
- under marginal costing the closing inventory is valued at variable production cost.
- Whereas under absorption costing, there is a share of fixed production costs in closing inventory.
IAS 2 Inventories – provides guidance for determining the cost of inventories and the subsequent recognition of the cost as an expense
Absorption costing has to be used for external reporting
Budgets serve several purposes (6)
- Planning annual operations
- Coordinating activities
- Communicating plans
- Motivating managers
- Controlling activities
- Evaluating performance
Developing budgets
Different organisations will produce budgets in different ways: (4)
- Participatory – managers at all levels are involved.
- Zero based budgeting – justify every figure in the budget (can be time-consuming)
- Incremental budgeting – start with prior period and adjust the figure (with percentages) (could add budgetary slack and become inaccurate)
- Rolling budgets – always have a budget for the next time period e.g. next 12 months
Stages in the Budgeting Process
- Communicate details of budget policy and guidelines to those people responsible for preparing the budget.
- Determine the factor that restricts output.
- Preparation of the sales budget.
- Initial preparation of budgets.
- Negotiation of budgets with higher management.
- Coordination and review of budgets.
- Final acceptance of budgets.
- Ongoing review of the budgets.
Types of budgets
- Sales
- Production including inventory levels
- Materials usage
- Materials purchase
- Labour utilisation
- Production overhead budget
- Functional budgets - eg. finance, admin
- Capital expenditure
- Cash flow
- Master, budgeted profit or loss and balance sheet
Budgetary control
We have already looked at why budgets are produced – the main reason is for _________ ___________.
So, once the budgets are completed, what happens?
The difference between the budget figures and the actual figures can be either a favourable variance or an adverse variance. (what do these mean)
We have already looked at why budgets are produced – the main reason is for control purposes.
They are compared to actual figures over the period so that those responsible can understand how they are performing.
Favourable = sales price increase = increase net profit
Adverse = cost of materials increase = decrease net profit
Budgetary control
There can be a variety of reasons for variances:
- Poorly set budget
- Inaccurate cost behaviour assumptions
- Change in suppliers
- Government changes – e.g. living wage
- International changes – e.g. price of oil
- Bad management
- High wastage
Budgetary control
So, once the budgets are completed, what happens? (2)
So, once the budgets are completed, what happens?
- They are compared to actual figures over the period so that those responsible can understand how they are performing.
- The difference between the budget figures and the actual figures can be either a favourable variance or an adverse variance.
Favourable or Adverse variance (2)
From the perspective of Net Profit
- Favourable
- Adverse (unfavourable)
What is a standard cost?
What is a budget? What is standard?
How do we establish standard cost?
- Standard costs are target costs for each operation that can be built up to produce a product standard cost.
- A budget relates to the cost for the total activity, whereas standard relates to a cost per unit of activity
Establishing standard costs: Two approaches:
- past historical records; Labour and Material usage
- engineering studies
What does Standard Hours Produced mean?
Standard (target) times: X = 5 hours, Y = 2 hours, Z = 3 hours
Output = 100 units of X, 200 units of Y, 300 units of Z
What is the Standard Hours Produced?
Standard Hours Produced
- Used to measure output where more than one product is produced.
Example
Standard (target) times: X = 5 hours, Y = 2 hours, Z = 3 hours
Output = 100 units of X, 200 units of Y, 300 units of Z
What is the Standard Hours Produced?
(100 × 5 hours) + (200 × 2 hours) + (300 × 3 hours) = 1,800 hours
- If actual DLH are less than 1,800 the department will be efficient,
- If hours exceed 1,800 the department will be inefficient.
Note: Different activity measures and other factors (besides activity) will influence cost behaviour.
Standard Hours Produced
Fixed and flexed budgets
What’s the difference?
- Once the flexed budget is produced…?
Fixed budgets remain the same irrespective of the level of activity.
A flexed budget changes with the level of activity. This is commonly used inmanufacturing businesses because if the level of activity changes, then every comparison between budget and actual will have variances – but this variance could be mainly due to activity levels being different.
- Once the flexed budget is produced, the variance analysis can be carriedout.
Note we are looking at variance analysis with a variable costing system
Sales volume variance
What is it?
A reduction in sales volume would lead to?
An increase in sales volume would lead to?
This variance handles the change from original budget to flexed budget.
As the only difference between these budgets is the level of activity, this variance considersthat in one figure.
- A reduction in sales volume would lead to an adverse variance.
- An Increase in sales volume would lead to a favourable variance
Direct labour efficiency variance
What is this?
- A reduction in the number of hours taken would lead to …?
- An increase in the number of hours taken would lead to …?
This variance compares the number of hours budgeted against the actual number of hours taken.
This difference is then shown at the budgeted hourly rate.
- A reduction in the number of hours taken would lead to a favourable variance.
- An increase in the number of hours taken would lead to an adverse variance
