What is costing• In cost accounting we analyse costs and calculate the cost

for each unit of production• Cost depends upon the judgement of the cost accountant in

each situation• The cost of a product purchased for resale is the price we

pay• If we make the product the cost of the product includes

Material, Labour and Overheads (other costs)• The cost of those units of a product sold is not the same as

the total cost of materials, labour and overhead since some of those costs may relate to unsold units

Page 3: COSTING

Example• Cost of one product: Product X

£

Material – 3 tons @ £5 per ton 15

Labour – 5 hours @ £1 per hour5

20

Overhead – 5 hours @£2 per hour 10

£30

Variable Costs

Fixed Costs

The overhead is Estimated and added to the cost of material and labour to give the total cost of Product X

Page 4: COSTING

Classification of Costs• Costs can be classified into the following areas

Fixed Costs; Variable Costs; Semi variable costs; Direct costs; Indirect Costs

• Exercise 1 Complete the definitions below• Fixed costs• These are costs which will not vary with output but may

change over time. eg Rent & Rates, Heating, Depreciation.

• Variable Costs• These are costs which WILL vary with output. The

more produced, the greater the cost eg material, labour, royalties

Page 5: COSTING

Classification of Costs• Semi Variable Costs• These costs have a FIXED and a VARIABLE part eg

maintenance costs will have a fixed level for standard repairs but will also include a variable element for unscheduled repairs

• Direct Costs• These are costs that can be traced back to a certain

product – eg cost of raw materials. They can be traced to a specific cost unit – eg wages

Page 6: COSTING

Classification of Costs• Indirect costs• These are costs which can’t be traced back to any

individual product – eg electricity, rent and rates etc

• In deciding the cost and possible selling price of a job, the direct costs of labour and material are easy to identify.

• The main problems arise in charging appropriate amounts for overhead and profit

Page 7: COSTING

Costing• To determine a fair manufacturing overhead for a job we

find a relationship between the total manufacturing overhead cost and some known direct costs.

• For example the overhead could be made up of a % of direct labour or of prime cost

• We may then add a profit % to the total cost to calculate the estimate selling price

• However• The customer and the market for the product decide the

actual selling price of the job

Page 8: COSTING

Job Costing

• Used to calculate manufacturing costs when the

organisation is making different product for

different customers

• Where each job is different

• Used by Contractors, builders, engineers

Page 9: COSTING

Job Costing

• Before an order for a job is placed the customer is given an estimate of the total cost which includes an estimate for materials and labour

• It is simpler to estimate material costs than it is labour costs

Page 10: COSTING

Page 11: COSTING

Exercise 3

Page 12: COSTING

Job Costing Card / StatementThis is prepared to keep a record of all the costs incurred in the job being undertaken.

• It includes the following details: 1. Job No2. Customer Order No3. Customer's Name4. Job Description5. Materials used and their cost6. Labour - time and cost7. Overhead charged8. Profit9. Total Price

Page 13: COSTING

Job Costing Card / Statement• Job Cards record actual labour time – taken from Clock

cards and time sheets From this actual labour costs can be calculated

• Material costs – taken from issue notes from stores or from invoices for material purchased specifically for a job

• Factory overheads - charged on an overhead absorption basis using one of the predetermined overhead absorption rate eg rate per machine hour

• Administration, selling and distribution overheads will also have to be charged.

• A percentage is added to the total cost for profit and to find the final price to charge the customer.

• An invoice will be prepared to bill the customer, it will include the information on the Job Cost Card.

Page 14: COSTING

Calculating Profit

• The profit can be calculated EITHER• as a percentage of total cost (mark-up)OR • as a percentage of the selling price of the job

(margin).

Page 15: COSTING

• The profit of a job is calculated on either the % of the cost price or on the selling price

• This means that a distinction must be made between the % Margin and the % Markup

• % Markup• Gross profit

Costs

Material Costs

• Costs in buying the parts (raw materials) necessary to produce the cost

unit

Labour Costs

• Wages of ALL of the workers who make the goods and services

(Assembly line workers etc AND managers etc)

Overheads

• The other costs of the running of the business – eg rent, heat etc

Page 27: COSTING

CALCULATING LABOUR COSTS

Various records are used in the calculation of wages:

• Personnel Records

• Salaries of workers

• Time Sheets/clock cards

• No of hours worked by employee

• Job Cards

• Time spent on a job and no of units produced

• Payroll

• Record of hours worked/ pay/ deductions to date

 

Page 28: COSTING

CALCULATING LABOUR COSTS

TIME RATE• Fixed hourly rate

Cost of one unit =

Hrs worked on the cost unit x Hrly rate

EG 40 HOURS PER WEEK @ £8 PER HOUR = £320

 

Page 29: COSTING

CALCULATING LABOUR COSTS

PIECE RATE

• Workers are paid for EACH ITEM produced

No of items produced x Rate per unit

EG - A worker produces 500 items

the rate per unit is £0.50

Wage = 500 × £0.50 = £250

 

Page 30: COSTING

CALCULATING LABOUR COSTS

BONUS SCHEME

• Paid in addition to hourly rate as an incentive for meeting targets

No of items produced x Rate per unit

If production of 5000 units are exceeded then a bonus of £0.20 per unit is paid

Therefore if 6000 units are produced then the bonus will be

(6000 - 5000) × £0.20 = £200 

Page 31: COSTING

CALCULATING LABOUR COSTS

OVERTIME PREMIUM

• Paid over and above hourly rate for extra hours worked

• Can be time and ½ or double time

EG If Hourly rate = £8 per hour

• Time and a Half = £8 × 1.5 for each hour of overtime worked

• Double Time = £8 × 2 for each overtime hour worked.

 

Page 32: COSTING

STOCK CONTROLAll forms of stock have a cost to the Business:

• Purchase price

• Storage costs e.g. warehousing costs - wages, heat and light

• Buying costs e.g. administration

• Insurance

• Pilferage (theft)/spoilage/damage

• Obsolescence - stock may go out of date and never be sold

• Opportunity Cost of the money used to buy the stock - i.e. what else could have been bought with that money

 

Page 33: COSTING

FIFOThis form of costing the direct materials used in any job values them at the same price as the OLDEST BATCH first

• Eg The first stock received into the warehouse will be the first stock to be used up

• If a stock room had

• 200 units at £5 = £1000 – received 1/1/ 12

• 200 units at £10 = £2000 – received 5/1/12

• If a job requires 300 units it will be issued 200 units @ £5 and 100 units at £10

• The cost of materials for the job would be £2000

• The balance would be 100 units at £10 = £1000 

Page 34: COSTING

LIFOThis form of costing the direct materials used in any job values them at the same price as the NEWEST BATCH first

• Eg The most recent stock received into the warehouse will be the first stock to be used up

• If a stock room had

• 200 units at £5 = £1000 – received 1/1/ 12

• 200 units at £10 = £2000 – received 5/1/12

• If a job requires 300 units it will be issued 200 units @ £10 and 100 units at £5

• The cost for materials would be £1500

• The balance would be 100 units at £5 = £500 

Page 35: COSTING

AVCOThis form of costing the direct materials used in any job values them at the AVERAGE PRICE of all materials available

(Existing units x p price)+(New units x p Price)

Total number of units in stock

• Eg The most recent stock received into the warehouse will be the first stock to be used up

• If a stock room had

• 200 units at £5 = £1000 – received 1/1/ 12

• 200 units at £10 = £2000 – received 5/1/12

All units in stock would be valued at £7.50(200 x £5)+(200 x £10)

400

• If a job requires 300 units it will be issued 300 units @ £7.50

• The cost for materials would be £2250

• The balance would be 100 units @ £7.50 = £750

OVERHEAD (INDIRECT) COSTING

These are costs related to the general production process itself

Examples:

• Materials not used in production of cost units

• Supervisors and non production labour wages

• General manufacturing expenses – rent/ rates etc

Therefore:

• Overheads are traced back (allocated) or shared out (apportioned) to COST CENTRES (areas which created the overheads and through which jobs will pass)

• Apportionment can be on a Blanket/standard rate or Departmenatl rates.

 

Page 43: COSTING

APPORTIONMENT (Sharing Out)

Overheads are SHARED FAIRLY between the cost centres which benefit from them eg:

 

Page 44: COSTING

APPORTIONMENT

Non traceable overheads to production and service departments

 

Department value for basis for apportionment

Total value for basis of apportionment (eg total area)

x Total value of overhead being reapportioned

For Example

Factory Rent £100,000

Area of Dept A 40,000 m2

Area of Dept B 10,000 m2

Total Area 50,000 m2

Apportioined to Dept A = 40,000 / 50,000 x £100,000

= £80,000

Apportioined to Dept B= 10,000 / 50,000 x £100,000

= £20,000

Page 45: COSTING

Reapportionment

• Overheads of service depts to production departments

• Done to show the benefit each Production dept gets from the service depts

Page 46: COSTING

Reapportion OH of Service Depts to production Depts

Department value for basis for apportionment (eg area)

Total value for basis of apportionment (eg total area)

x Total value of service dept OH being reapportioned

For Example

Stores Overheads £90,000

Raw materials used by Dept A 10,000 units

Raw materials used by Dept B 20,000 units

Total Materials 30,000 units

Apportioined to Dept A = 10,000 / 30,000 x £90,000= £30,000

Apportioined to Dept B= 20,000 / 30,000 x £90,000= £60,000

Page 47: COSTING

Overhead Absorption rates

• Calculated AFTER allocation and apportionment to production depts

• Calculated in a manner which best represents the way that a job makes use of the departments resources

Predetermined overhead rates

• Quite often these are set by an organisation rather than actual overhead rates.

• They are based on the average costs of average production.

BUT

• The amount charged to jobs might be too little (under absorption)

• Or it might be too much (over absorption)

In case A there has been an under absorption of £50,000 (the budgeted machine hours were more than the actual machine hours)

In case B there has been an over absorption of £20,000 (the actual overhead incurred is less than the budgeted one)

Page 55: COSTING

Summary Overhead Apportionment and Absorption

1. Overheads are apportioned or allocated to each production / service dept

2. Service department overheads are then re-apportioned to the production departments

3. Appropriate overhead absorption rates are calculated

4. The overhead costs are absorbed (taken into consideration when costing a job or making a product by applying a certain rate

Service/Operating Costing

• An estimated cost of providing services rather than products• Used by Hospitals, dental practices, lawyers etc• Estimated cost calculated over a year - in the most

appropriate units – eg hospital (patient/ days), Restaurant (meals served)

WHY• Enables comparison between cost of hiring/leasing and

owning equipment• Determines how much other cost centres should be charged

for the use of the service• Determines price for service to ensure profit • Promote efficiently – can compare prices charged between

Process Costing

• Used in industries where the end product is more or less identical

• unit cost = costs of production/ number produced (over a time period)

• Units pass through a series of production stages until final completion

• Each production dept transfers its completed production to the next department where it becomes the input for further processing

• The completed item is transferred from the last department to the finished goods stock

• Costs from one department to another are cumulative

Page 68: COSTING

Process Costing

Normal/ Uncontrollable Loss• Losses which occur under efficient operation

conditions• These are absorbed by the production of the itemAbnormal/ Controllable Loss• Losses which are not expected to occur under

efficient operating conditions eg incorrect cutting of cloth

• These are removed from the appropriate process account• Reported separately as an abnormal loss• Treated as a cost and written off to the P&L account

Page 69: COSTING

Process Costing

Calculating the transfer of goods between processes• Calculate the unit cost of production (establish

expected output) eg• In a process there is an input of 1,200 gallons

costing £1• An output of 1,000 gallons is expected• Therefore normal loss for this process is 200 gallonsCost of production £1200 £1.20Expected output 1,000

Page 70: COSTING

Process Costing Accounting for the sale of scrap• Sometimes process losses can be sold for some small value• The resulting sales revenue should be offset against the costs

of the appropriate process• Therefore

Cost of production less scrap value of normal lossExpected output

• If the normal loss from the last example had a scrap value of 50p per unit then

£1200 - 100 £1100 £1.10 1,000 1,000

• If the production had actually only been 900 units then there would be normal loss of 200 units and abnormal loss of 100

Page 71: COSTING

Process Costing WORK IN PROGRESS• When a process account is drawn up there will be some

material in each process which is partly finished• This work in progress must be valued and accounted for• Work in progress consists of direct materials labour and

overheadsABNORMAL LOSSThis is unexpected loss due to carelessness, inferior material

etcAn abnormal loss account is opened and the total cost of the

abnormal loss charged to it.The units lost unexpectedly are charged at the unit price of

actual output.

Break Even

What is Break Even?

Break even is a process that shows organisations how many units they must produce and sell in order to cover their costs. It allows them to see when they start to make a profit.

What Costs are associated with Break Even?

There are three types of costs:

•Fixed Costs

•Variable Costs

•Semi Variable costs

Page 75: COSTING

Break Even - Costs

FIXED COSTS

Fixed Costs are costs that don’t change(constant) in relation to output. These are TIME BASED COSTS.

VARIABLE COSTS

•Variable costs are costs that change with output. These are ACTIVITY BASED COSTS

SEMI VARIABLE COST

This is a combination of a fixed cost and a variable cost.

Page 76: COSTING

Break Even - Costs

Total Costs

Fixed Costs and Variable Costs = Total Costs

If Sales (revenue) > than Total Costs = Profit

If Sales (revenue) < than Total Costs = Loss

If Sales (revenue) = Total Costs = Break Even Point.

Break Even Point is the level of sales where the company neither makes a profit or a loss (simply cover their costs)

Page 77: COSTING

Benefits Of Break Even For Managers

• The level of Break Even is important for Managers as it indicates specifically the level of output required to generate a profit

• It illustrates the returns an organisation should get at each level of output

• It clearly indicates information on a firm’s MARGIN OF SAFETY (level above Break Even)

Break Even

From the chart above we can see immediately that the break even point is 50 units or At Sales Revenue equal to £100

The area above break even point is referred to as the margin of safety. This indicates to managers the level of output they can expect to drop before hitting the break even point.

Page 81: COSTING

Calculating Break Even

CONTRIBUTION

This is the difference between the Selling Price and the Variable Cost. The difference between what it cost to make and what you are selling it for

Contribution is that part of the Selling Price that ‘contributes’ towards paying off the Fixed Costs

Page 82: COSTING

Break Even Calculations

Contribution = Selling Price – Variable Cost

BEP (Units) = Fixed Costs / Contribution

Sales Revenue at BEP = (FixedCosts/Contribution)*Selling Price

Target Profit = (Fixed Costs + Target Profit)/ Contribution

Profit/Loss (units)= Total Contribution – Fixed Costs

(Total Contribution = Contribution per unit * No of units sold)

Margin of Safety (In sales) = Actual Sales output – Sales at Break even point (to convert to units divide answer by selling price per unit)

PVR (profit volume ratio) = Contribution/Selling Price * 100

b) Variable cost per unit

Variable cost per unit = Total costs per unit – Fixed costs per unit

Variable costs per unit (use BE values) =

( 20,000 – 10,000) / 2,500 units

= £4 per unit

Page 85: COSTING

Example exercise (Int 2)c) Contribution per unit

Selling price per unit – Variable cost per unit

Using previous answers £8 - £4 = £4 per unit

d) Profit from 3,500 units

(Using graph) 3,500 units = Sales £28,000

3,500 units = Total costs £24.000

35,000 units – Profit = £4,000

Easier method £4 per unit contribution

Contribution x Units above break even = profit

= £4 x 1000 units = £4,000

Page 86: COSTING

Example exercise (Int 2)v) Sales required to make a profit of £14,000

Target Profit = (Fixed Costs + Target Profit)/ Contribution

£14,000 = (10,000 +14,000) / 4

= 24,000/4 = 6,000 units

ExampleMFL plc manufactures and sells patio chairs.

It is estimated that the Fixed Costs for year 1 will be £72,000. The labour cost is £6 per chair and the material to make each chair costs are £10. Each chair sells for £24.

 You have to calculate the following:

i. Contribution per chair

ii. Break Even Point in Units

iii. Sales Revenue at Break-Even Point

iv. Number of chairs to be sold to make a profit £4000

 You have to calculate the following:

iii.  Sales Revenue at Break-Even Point

Sales Revenue at BEP = (FixedCosts/Contribution)*Selling Price

(£72,000 /£8 ) * 24 = £216,000 (must have £ in exam)

iv. Number of chairs to be sold to make a profit of £4000

Target Profit = (Fixed Costs + Target Profit)/ Contribution

= (£72,000 + 4,000) / £8 = 9500 chairs (must mention units in exam)

Page 90: COSTING

Margin of Safety The Margin of Safety is the distance between actual sales

achieved and the sales level needed to break-even. Actual Sales - Sales at Break Even Point

It can be measured in units or sales revenue terms.

A narrow margin of safety would indicate that a small fall in volume of sales might have a significant effect on profits.

 A wide margin would mean that there would have to be a large fall in sales volume before the BEP was reached.

 A wide margin of safety is therefore desirable if a firm is going to cope with competition and decreases in demand.

An increase in selling price could improve the margin of safety whilst an increase in fixed costs (with no corresponding changes in contribution and sales volume) would reduce the margin of safety 

Page 91: COSTING

Total cost includes several elements which have to be added together. Marginal Costing requires that total cost be classified into fixed and variable costs.

On a Break-even Chart the total cost line is a combination of the fixed costs and the variable costs.

At nil level of activity the total costs will equal the fixed costs.

 Where the total cost line intersects the sales line an angle of incidence is formed

Total Costs

Page 92: COSTING

• Profit in this ratio refers to contribution

• Volume refers to total sales value

• The P/V Ratio does not mean profit in relationship to sales but the contribution in relation to sales

Formula = (Contribution / Sales ) *100

• The Profit/Volume Ratio (P/V) shows the contribution as a percentage of sales.

• With higher percentage the contribution towards the fixed costs will be greater and profits will be achieved earlier

• The P/V ratio can be improved by - increased selling prices, reduced variable costs; concentrating on those products which provide the highest contribution.

Profit/Volume ratio

Page 93: COSTING

Assumptions of Break Even ASSUMPTION LIMITATION

There is only one product being produced.

This is likely to be the case in very few businesses.

The selling price per unit is constant throughout the range of output. (ie straight line)

It may be necessary to lower prices to achieve higher levels of output, and if output falls a business may cut prices to attract sales.

The variable cost per unit is constant throughout the range of output i.e. it is proportionate to output.

At higher outputs it may be necessary to pay overtime rates to increase production, but this may be offset to some extent by achieving quantity discounts on purchases of raw materials

Page 94: COSTING

Assumptions of Break Even

ASSUMPTION LIMITATION

Fixed Costs are constant (i.e. a horizontal line on the graph) throughout the production range.

Fixed costs are not fixed forever. There will for instance be a need for more machinery at very high output levels which will increase depreciation and perhaps more space will be required leading to higher rent etc in the long run

All costs can be classified as fixed or variable

There are semi-variable costs which do not behave according to the break-even model

All output is sold There will be opening and closing stocks to be taken into account in most cases.

Page 95: COSTING

Marginal Costing

• Marginal Costing is a decision-making tool which focuses on variable costs and variable incomes

• It ignores fixed costs

CONTRIBUTION

• The difference between the SELLING PRICE of a product and its VARIABLE COST of production

• Any product which makes a contribution is potentially worth making

CALCULATING PROFIT

• Profit = Total contribution – Fixed costs

If possible all products making a positive contribution would be produced

However there is usually a “Limiting Factor” which determines how much can be produced.

Page 96: COSTING

Marginal Costing LIMITING FACTOR

The factor that limits profits eg

• Skilled labour

• Machine capacity

• Raw materials

The limiting factor must be used in such a way that contribution is maximised

You must maximise contribution by

• Labour hour

• Machine Hour

• Unit of materials – eg per kilo

MARGINAL COSTING - SUMMARY Focuses on variable costs and variable incomes. Step 1 - work out the contribution per unit.Contribution = unit selling price - unit variable cost. Step 2 – work out the contribution per unit of limiting factor eg (machine or labour hours or kilos, £s or units of raw material) Step 3 – work out production order – highest contribution firstStep 4 – take account of any complication – eg redo production order to take account of any contractual obligations or company policyStep 5 – Work out total contribution and then deduct total fixed costs to give Profit

NOTE – IF FIXED COSTS ARE GIVEN IGNORE THEM WHEN CALCULATING CONTRIBUTION

Page 111: COSTING

Introducing a new product

When introducing a new product you need to:

1.Work out its unit contribution to see if it is viable or not (anything with a negative contribution will not be worth making)2.calculate its contribution per limiting factor and then place it in the production order in the appropriate place3.Recalculate how many of each product you can make4.Calculate the total contribution 5.If asked to find the Total Profit you must deduct the fixed costs

Page 112: COSTING

Introducing a new product - Example Exercise

A business is working at full capacity and a new product is being considered. for example:

Current production: •5000 units of A earning a contribution of £20 in 2 machine hours,•4000 units of B earning a contribution of £15 in 3 machine hours,•2000 units of C earning a contribution of £20 in 5 machine hours.

Should a special order of 2,000 units at £8 each be accepted

Is the capacity there Yes 20,000 is 80% so full capacity is 25,000Is there a contribution at the new price?Yes SP (£8) – VC (£6) = Cont (£2)

MARGINAL COSTING – Make or Buy Decisions

OPPORTUNITY COSTThe opportunity cost of an item can be described as the cost of what you give up to produce it.

Example – a business working at full capacity (so time is a limiting factor) makes Product Z , which earns a contribution of £20. It takes 2 hours to produce and therefore makes a contribution of £10 per hour

If it then decides to do something else then one of the “costs” of that “something else” must be the fact that it is no longer earning £10 per hour from making Z

Page 125: COSTING

MARGINAL COSTING – Make or Buy Decisions

OPPORTUNITY COSTAnother example of opportunity cost would be a business making a product which contains a component and it is considering purchasing the component instead of making it.

RULES TO REMEMBERIf the firm has spare capacity it is pointless purchasing it if you can make it cheaper

However if there is no spare capacity then the time saved by not making one component could be used to earn more contributions making another

Page 126: COSTING

MARGINAL COSTING – Make or Buy Decisions

Data for Product X – working at full capacity

Selling Price £50

Materials £10

Part Y £10

Labour (2 hours) £16

Contribution £14

• It is currently making £7 per hour contribution

• (£50 (SP) - £36 (VC) = £14 per unit

• Each unit takes 2 hours so contribution = £7 per hour

• Part Y can be purchased from outside for £12• The time saved making Part Y can be used to earn more contributions

making the rest of the product• Therefore (assuming Part Y takes ½ an hour to produce) the true cost of

Part Y is £10 PLUS £3.50 (½ of the £7 per hour contribution for product x) in lost contributions = £13.50

• The company should therefore purchase the component from an outside supplier as they supply it for £12

Page 127: COSTING

MARGINAL COSTING – May or Buy Decisions

Example Exercise 2• Tango requires 10 hours to produce and sells for £50. • It has a marginal cost of £20 (variable cost)• Samba could also be made. It takes 4 hours at a marginal /variable

cost of £15. A supplier has offered to make it for £ 20a) Should it be bought or manufactured if there is surplus capacity?

Manufactured b) Should it be bought or manufactured without surplus capacity • If Samba is bought in then the hours saved making it can be used to

make more of Tango • Opportunity cost = 4hours (time saved per Unit of samba) x £3

( hourly contribution for Tango) = £12• True cost of producing Samba therefore is £15 + £12 = £27

Therefore it should be purchased from outside for £20

Contribution Tango - £50 - £20 = £30Hourly contribution = £30 / 10 hours = £3

Page 128: COSTING

MARGINAL COSTING – May or Buy Decisions

Example Exercise 3• Component X requires 3 hours to produce and makes a unit

contribution of £4.50. (Hourly cont £4.50/3 hours = £1.50 per hour)• Component Y could also be made. It takes 4 hours at a marginal

cost of £ £15.• A supplier has offered to make it for £ 22.

a)Should it be bought or manufactured if there is surplus capacity? Manufactured

b): Should it be bought or manufactured without surplus capacity • If Component Y is bought in then the spare hours can be used to

make more of Component X• Opportunity cost = 4hours (time saved per Unit from Component

Y) x £1.50 (hourly contribution for Component X= £6• True cost of producing Component Y therefore is £15 + £6 = £21• Therefore it should NOT be purchased from outside as it costs

more than the cost of manufacture + the opportunity cost

MARGINAL COSTING – Retain or Close

• Marginal costing can be used to help a business to decide whether to keep or drop a product/department which appears to be making a loss or to keep a factory open when it is losing money

• If a department/ product is making a loss the management should aim to reduce this loss

• When making a decision they must decide• Whether another product can be made instead to increase

contribution• Whether to close the department and sell the assets to raise

money for other departments• Whether the product making a loss is connected to other

products and if discontinued will affect their sales• They must also look closely at what will happen to fixed costs

The management wishes to stop producing any loss making product. However if C is no longer produced, it might at first seem that there would be a saving of £7,000,but this is not necessarily the case. The firm’s total fixed cost bill is £36,000.It will still be £36,000 if C if not produced. If it is not being charged to C, it will have to be charged to A and B.

MARGINAL COSTING RETAIN OR CLOSE A DEPT/PRODUCT

The overall profitability has fallen from £19,000 to £14,000, i.e. by £5,000 because there is no longer a contribution of £5,000 from CIf, however, you are told that as a result of not making C there will be a reduction in fixed costs of £8,000 (because, for example, part of the premises will no longer be used) this would have to be taken into account.E.g. If C is not produced - lose £5,000 contribution, save £8,000 in fixed cost, overall gain £3,000, so C should not be produced..

MARGINAL COSTING PROFIT PLANNING

• Where a number of different options are possible chose the one which maximises total contribution

• In some instances it will be necessary also to take into account any changes in total fixed costs e.g. a reduction in fixed costs has the same effect as if it were additional contributions

Example• Smith & Sons is working at less than full capacity making and selling a

product which has a contribution of £5 per unit.• Annual sales are 10,000 units.• Fixed costs are £20,000• The Production Manager wants to purchase a new machine which will

cut variable costs per unit by £1, but it will add £5,000 per annum to fixed cost.

Limitations of Financial Accounting system alone

• It is historical i.e. it is out of date therefore it is too late to change anything now for that time of year!

• It is in total form (e.g. the total profit earned by the whole business last year). This - doesn’t say anything about the success of individual products

• Layout is dictated by outsiders e.g. FRS – lacks detail• Does not apply to areas of responsibility - the Production

Manager, for example, does not know what cost levels are expected to be achieved in the factory.
