Marginal costing
A TECHNIQUE USED IN DECISION MAKING
- If the volume of output increases, the average cost per unit will decrease. Conversely, if the output is reduced, the average cost per unit will go up

CVP Analysis
a method for analysing how operating and marketing decisions affect net income
CVP model:
Profit = Revenue – Total cost
= Q x SPU – Q x VCU - FC

Strategic role of CVP analysis
• Cost leadership firms compete by increasing volume to achieve low per unit operating cost- predict effect of volume on profit and risk of increasing FC
• Early stage of cost life cycle- predict the profitability of the product
• Use in target costing – profitability of alternative designs• Later phases of life cycle- mfg. stage- evaluate most
profitable mfg. process• Helps in strategic positioning- - differentiation- assessing desirability of new features - cost leadership- low cost operating means

Some terms
• Operating income = Gross operating revenue – COGS and operating costs
• Net income = operating income + net non-operating revenues – income tax
• Contribution margin = contribution margin per unit X No. of units sold
![Page 9: Cost Volume Profit Analysis A tool for decision making Source- Cost Accounting – A managerial emphasis by Horngreen, Datar & Foster [ Chapter-3]](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649e5f5503460f94b58dc3/html5/thumbnails/9.jpg)
BEP
Equation method:Revenue-variable cost – fixed cost = operating income
[SP X Q] – [VCU X Q]- FC = Operating income
At BEP, operating income = “Zero”
![Page 10: Cost Volume Profit Analysis A tool for decision making Source- Cost Accounting – A managerial emphasis by Horngreen, Datar & Foster [ Chapter-3]](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649e5f5503460f94b58dc3/html5/thumbnails/10.jpg)
BEPContribution margin method: rearranging the
equation
[SP X Q]- [VCU X Q] –FC = OI
Or, [SP-VCU] X Q = FC + OI
At BEP, [SP-VCU] X Q = FC
i.e., CMU X Q = FC
Hence, Q = FC / CMU (in terms of number)
Q = FC / PV ratio (in terms of revenue)
![Page 11: Cost Volume Profit Analysis A tool for decision making Source- Cost Accounting – A managerial emphasis by Horngreen, Datar & Foster [ Chapter-3]](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649e5f5503460f94b58dc3/html5/thumbnails/11.jpg)
PV ratio
PV ratio = CMU/SP - a % figure - a rate of profitability
Uses of PV ratio:– 1- P/V ratio = Variable cost ratio– Sales X P/V ratio = Gross contribution– Determining the sales mix – BEP = FC / PV Ratio– [FC+ Target Profit ] / PV ratio gives the volume of
output to be sold to earn a desired level of output
![Page 12: Cost Volume Profit Analysis A tool for decision making Source- Cost Accounting – A managerial emphasis by Horngreen, Datar & Foster [ Chapter-3]](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649e5f5503460f94b58dc3/html5/thumbnails/12.jpg)
Improving PV ratio
improvement in P/V ratio will mean more profit– reduce variable cost– increase selling price– product mix to change in favour of high P/V
ratio products– Change in FC?

Assumptions
• Volume is the revenue and cost driver
• Total cost can be segregated into fixed and variable components
• Total revenue and cost are linear functions of volume within relevant range and time
• Selling price, VC per unit and fixed cost are known and constant within relevant range and time
• Applicable to single product or multi-product situation with constant sales mix as volume changes

mean?• Monopoly- plant efficiency v. angle of incidence• Competition- plant efficiency v. angle of

Target operating income
Means a target contribution marginQ = [Fixed cost + Target OI] / CMUUnderstanding impact of IT:Target net income:= Target OI- Target OI X Tax rateSo, Target OI = Target NI / [1 – tax rate]Hence, Q = [FC + Target NI / [1 – tax rate]]

Improving MOS
• Reduce FC
• Increase sales volume
• Selling more profitable products
• Reduce VC
• Increase in selling price in case of demand inelastic products

- Substitution of fixed cost for VC results in more risk of loss (higher BEP) but offers a greater profit as revenue increases.
Learning:
CVP analysis helps in evaluating various FC/VC structures

Operating leverage
- Marry wants to sell 40 units @Rs.200/unit with purchase cost of Rs.120/unit
Cost options:Option-I Option-II Option-III
Rs.2000 FC Rs.800 FC + 15% of Revenue 25% of Revenue
OI: Rs.1200 Rs.1200 Rs.1200
BEP: 25 units 16 units 0 units
MOS= 15 units 24 units 40 units
If no. of units sold drops to 20 units: option I will give operating loss.
If no. of units sold is 60, option I will give highest OI of Rs.2800.

Learning:
Moving from I to III: Marry faces less risk of loss when demand is low, but looses opportunity for higher OI when demand is high.
Choice of cost structure: confidence in demand projection and ability to bear loss
- Operating leverage measures this risk-return trade-off
![Page 23: Cost Volume Profit Analysis A tool for decision making Source- Cost Accounting – A managerial emphasis by Horngreen, Datar & Foster [ Chapter-3]](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649e5f5503460f94b58dc3/html5/thumbnails/23.jpg)
Cont……..
- Operating leverage describes the effects that fixed costs have on changes in OI as changes in sales volume happens, and, hence in contribution margin.
- High FC and lower VC means, higher operating leverage: small increase in sales results in large increase in OI and small decrease means large decrease in OI leading to greater risk of operating loss.
- At a given level of sales: degree of operating leverage = contribution margin / operating income
![Page 24: Cost Volume Profit Analysis A tool for decision making Source- Cost Accounting – A managerial emphasis by Horngreen, Datar & Foster [ Chapter-3]](https://reader036.vdocuments.us/reader036/viewer/2022062516/56649e5f5503460f94b58dc3/html5/thumbnails/24.jpg)
Cont….. Option-I Option-II Option-III1. CMU Rs.80 Rs.50 Rs.302. CM Rs.3200 Rs.2000 Rs.12003. OI Rs.1200 Rs.1200 Rs.1200Degree of Operating leverage 2.67 1.67 1.00[DOL]
DOL is specific to a given level of sales as starting point. If the starting point changes, DOL changes
Interpretation: Change of sales by 50% would change the OI under option-I by 50% X 2.67, i.e., by 133%

trade-off at amazon.com
- Amazon.com- virtual model- no warehousing and inventory cost, but cost of books is high
- Barnes & Noble- brick & mortar model- purchased from publishers with lower cost- high fixed cost
- Amazon went for acquisition of distribution centres (increased FC, Operating Leverage, risk, but lower VC)

Effect of time
Whether a cost is fixed or not, depends on:
1. Relevant range
2. Time horizon
3. Decision in hand

CVP Analysis for ABC
Find out cost drivers for batch level FC and on the basis of batch size relate it to product VC. So, FC reduces, MCU also changes. New BEP is arrived at.
