Use it to quickly identify the expected analysis, choose the right calculation, and connect quantitative results to case-specific recommendations.

Core 2 Case Response Pattern

Case signalWhat to doCommon trap
“Evaluate,” “assess,” “recommend”State criteria, quantify if useful, compare options, recommend with case factsListing pros/cons without a conclusion
“Budget,” “forecast,” “plan”Identify assumptions, build the schedule, test sensitivity, comment on reliabilityTreating management estimates as automatically reasonable
“Control weakness”Weakness → implication/risk → recommendationNaming a generic control without explaining the risk
“Variance”Calculate flexible-budget variance where relevant, classify F/U, explain operational causeCalculating only arithmetic variance with no business interpretation
“Pricing”Identify cost base, capacity, competition, strategy, customer sensitivityUsing full cost as the only answer
“Make/buy/drop/special order”Include only relevant future differential cash flowsIncluding sunk costs or unavoidable allocated fixed costs
“Performance evaluation”Match measure to responsibility centre and controllabilityPenalizing managers for uncontrollable costs
“Strategic option”Link to mission, capabilities, risks, constraints, financial impactRecommending the highest profit option without feasibility analysis

High-Yield Management Accounting Formulas

Contribution, Break-Even, and CVP

\[ \text{Contribution margin per unit} = \text{Selling price per unit} - \text{Variable cost per unit} \]\[ \text{Contribution margin ratio} = \frac{\text{Contribution margin}}{\text{Sales}} \]\[ \text{Break-even units} = \frac{\text{Fixed costs}}{\text{Contribution margin per unit}} \]\[ \text{Break-even sales dollars} = \frac{\text{Fixed costs}}{\text{Contribution margin ratio}} \]\[ \text{Target profit units} = \frac{\text{Fixed costs} + \text{Target operating income}}{\text{Contribution margin per unit}} \]\[ \text{Margin of safety} = \text{Actual or expected sales} - \text{Break-even sales} \]\[ \text{Degree of operating leverage} = \frac{\text{Contribution margin}}{\text{Operating income}} \]
CVP issueExam handling
Multi-product break-evenUse weighted-average contribution margin based on sales mix
Constrained resourceRank products by contribution margin per scarce resource unit
High fixed-cost structureHigher operating leverage; profit is more sensitive to sales changes
Uncertain assumptionsSensitivity analysis: price, volume, variable cost, fixed cost, mix
Non-profit or public-sector settingReplace “profit” with required surplus, funding gap, or cost recovery target

Cost Behaviour and Classification

Cost typeDefinitionExampleCore 2 use
Variable costChanges in total with activityDirect materialsCVP, relevant costing, flexible budget
Fixed costConstant in total within relevant rangeRent, salaryBreak-even, capacity analysis
Mixed costContains fixed and variable componentsUtilitiesSeparate using high-low or regression if data supports it
Step costFixed within bands; jumps at thresholdsSupervisor salaryWatch capacity thresholds
Direct costTraceable to cost objectMaterials for productProduct/service costing
Indirect costNot easily traceablePlant overheadAllocation, ABC
Product costInventoriable under absorption costingDM, DL, manufacturing OHInventory and cost of goods sold
Period costExpensed in periodSelling, adminDo not invent inventory treatment
Controllable costInfluenced by managerDepartment suppliesPerformance evaluation
Uncontrollable costNot influenced by managerHead office allocationExclude from manager evaluation where possible

High-Low Cost Estimation

\[ \text{Variable cost per unit} = \frac{\text{Cost at high activity} - \text{Cost at low activity}}{\text{High activity units} - \text{Low activity units}} \]\[ \text{Fixed cost} = \text{Total cost} - (\text{Variable cost per unit} \times \text{Activity units}) \]

Use high-low only when a quick estimate is acceptable. Mention limitations: uses two observations, may be distorted by outliers, ignores seasonality and structural changes.

Costing Systems and Allocation

MethodBest fitCalculation focusExam traps
Job-order costingCustom jobs, projects, batchesAssign direct costs and applied overhead to each jobForgetting over/underapplied overhead
Process costingHomogeneous mass productionEquivalent units and cost per equivalent unitMixing weighted-average and FIFO logic
Activity-based costingDiverse products, complex overhead driversCost pools × activity driversAssuming ABC is always worth the implementation cost
Standard costingRepetitive operations with benchmarksStandards × actual/flexible activityStandards may be outdated or unrealistic
Absorption costingExternal inventory costing contextProduct includes variable and fixed manufacturing costsTreating fixed manufacturing OH as period cost
Variable costingInternal decision-makingProduct includes variable manufacturing costs onlyDifference from absorption depends on inventory changes
Joint costingProducts from common processAllocate joint costs after split-offJoint costs are not relevant to sell/process further decisions

Predetermined Overhead and Applied Overhead

\[ \text{Predetermined overhead rate} = \frac{\text{Budgeted overhead}}{\text{Budgeted allocation base}} \]\[ \text{Applied overhead} = \text{Predetermined overhead rate} \times \text{Actual allocation base used} \]
ResultInterpretation
Actual overhead > applied overheadUnderapplied overhead
Actual overhead < applied overheadOverapplied overhead

ABC Quick Setup

StepQuestionExample
Identify activitiesWhat consumes resources?Setups, inspections, purchase orders
Create cost poolsWhat costs belong together?Setup labour and setup supplies
Choose driversWhat causes the activity?Number of setups
Compute driver ratePool cost divided by driver volumeSetup cost per setup
Assign costDriver rate × usageProduct A uses 40 setups
InterpretWhich products/customers are subsidized?Low-volume complex products may be undercosted under traditional costing

Budget Review Checklist

  • Are assumptions consistent with case facts and external conditions?
  • Are fixed, variable, and step costs treated appropriately?
  • Is capacity sufficient for the forecast volume?
  • Are one-time costs separated from recurring costs?
  • Are working capital and cash timing considered?
  • Are budgets aligned with strategy and operational constraints?
  • Is there risk of budgetary slack or unrealistic stretch targets?
  • Are non-financial drivers included, not just dollars?

Variance Analysis

Variance Interpretation Rules

TermMeaningBe careful
Favourable varianceActual result improves income versus benchmarkFavourable is not always good; may indicate quality cuts or underinvestment
Unfavourable varianceActual result reduces income versus benchmarkMay be acceptable if tied to strategic investment
Price/rate varianceDifference in input price or wage rateProcurement, market conditions, supplier quality
Quantity/efficiency varianceDifference in input usageWaste, training, process design, material quality
Spending varianceActual cost differs from flexible budgetOften used for overhead
Volume varianceOutput differs from denominator/budgeted volumeCapacity utilization issue, not necessarily spending control

Standard Cost Variances

VariancePlain formulaTypical cause
Direct material priceActual quantity × (actual price - standard price)Supplier price, bulk discounts, rush orders
Direct material quantityStandard price × (actual quantity - standard quantity allowed)Waste, defects, material quality
Direct labour rateActual hours × (actual rate - standard rate)Wage mix, overtime, labour market
Direct labour efficiencyStandard rate × (actual hours - standard hours allowed)Training, downtime, complexity
Variable overhead spendingActual VOH - (actual driver units × standard VOH rate)Utility rates, indirect supply prices
Variable overhead efficiencyStandard VOH rate × (actual driver units - standard driver units allowed)Driver inefficiency
Fixed overhead budgetActual fixed OH - budgeted fixed OHFixed cost control
Fixed overhead volumeBudgeted fixed OH - applied fixed OHCapacity utilization
Sales priceActual quantity sold × (actual price - standard price)Discounting, market pressure
Sales volumeStandard contribution margin × (actual quantity - budgeted quantity)Demand, sales execution

Flexible Budget Logic

\[ \text{Flexible budget variable cost} = \text{Standard variable cost per unit} \times \text{Actual activity} \]\[ \text{Flexible budget contribution margin} = \text{Actual units} \times \text{Budgeted contribution margin per unit} \]

Use a flexible budget when actual activity differs from planned activity. Static-budget variances combine volume effects and cost-control effects, making them less useful for management action.

Pricing Decisions

Pricing approachWhen usefulRisk
Cost-plusCustom jobs, regulated/contract environments, cost recoveryIgnores market demand and competitor prices
Market-basedCompetitive markets with clear alternativesMay not recover costs if cost structure is weak
Value-basedDifferentiated products/servicesRequires strong customer insight
Target costingMarket price is constrained; design to cost targetMay force quality or feature trade-offs
Penetration pricingBuild volume or market shareLow margin, hard to raise prices later
Skimming pricingNew differentiated offeringAttracts competitors, limited volume
Relevant-cost pricingShort-term decisions with unused capacityDangerous for long-term pricing
\[ \text{Target cost} = \text{Target selling price} - \text{Target profit} \]

Exam response: do not recommend a price using only a calculation. Address capacity, strategy, customer reaction, competitor response, long-term profitability, and implementation.

Transfer Pricing

\[ \text{Minimum transfer price} = \text{Variable cost per unit} + \text{Opportunity cost per unit} \]
SituationTransfer price floorTransfer price ceilingDecision point
Selling division has idle capacityVariable cost plus incremental costsExternal purchase priceInternal transfer often beneficial
Selling division has no idle capacityVariable cost plus lost contribution marginExternal purchase priceTransfer only if group benefit exists
External market existsMarket price is a strong benchmarkMarket price or external purchase costSupports divisional autonomy
No external marketCost-based or negotiated priceBuyer’s alternative costHigher risk of disputes
Goal is behaviour controlUse negotiated range plus policyBuyer’s alternative costBalance autonomy and goal congruence
MethodProsCons
Market-basedObjective, supports performance evaluationMarket price may not exist or may fluctuate
Variable-cost-basedEncourages internal use of idle capacitySelling division may show poor performance
Full-cost-basedSimple, recovers costsCan pass inefficiencies to buying division
Cost-plusProvides profit to selling divisionMarkup may be arbitrary
NegotiatedEncourages autonomyTime-consuming; power imbalance

Capital Budgeting and Investment Analysis

\[ \text{NPV} = \sum \frac{\text{Cash flow}_t}{(1+r)^t} - \text{Initial investment} \]\[ \text{Payback period} = \frac{\text{Initial investment}}{\text{Annual cash inflow}} \]
MethodDecision ruleStrengthWeakness
NPVAccept if NPV is positive, compare highest value subject to constraintsConsiders time value and cash flowsSensitive to assumptions
IRRCompare to required returnEasy to communicateCan mislead with non-conventional cash flows or mutually exclusive projects
PaybackShorter payback preferredLiquidity and risk focusIgnores cash flows after payback and time value unless discounted
Accounting rate of returnCompare accounting profit to investmentUses accounting dataNot cash-flow based
Profitability indexPresent value of inflows divided by investmentUseful under capital rationingScale issues

Capital Budgeting Case Checklist

  • Use cash flows, not accounting income, unless specifically asked.
  • Exclude sunk costs.
  • Include opportunity costs.
  • Include incremental working capital and recovery timing.
  • Include disposal proceeds and decommissioning costs if relevant.
  • Match nominal cash flows with nominal discount rates, and real cash flows with real discount rates.
  • Test sensitivity for sales volume, price, cost escalation, discount rate, and useful life.
  • Discuss strategic fit, operational risk, financing capacity, and implementation constraints.

Responsibility Accounting and Performance Measures

Responsibility centreManager controlsSuitable measuresUnsuitable emphasis
Cost centreCosts, efficiency, service qualityCost variance, service levels, quality metricsRevenue or profit not controlled
Revenue centreSales volume, price within authorityRevenue, market share, customer acquisitionCosts outside manager control
Profit centreRevenues and costsContribution, controllable profit, marginCorporate allocations not controlled
Investment centreProfit and assets employedROI, residual income, asset turnoverProfit alone without capital usage
\[ \text{ROI} = \frac{\text{Operating income}}{\text{Average operating assets}} \]\[ \text{Residual income} = \text{Operating income} - (\text{Required return} \times \text{Average operating assets}) \]
MeasureBest useTrap
ROICompare efficiency of investment centresCan discourage positive-NPV investments that reduce divisional ROI
Residual incomeEncourage value-creating investmentsHarder to compare divisions of different sizes
Contribution marginShort-term product/customer decisionsIgnores fixed costs and capacity
Gross marginProduct profitability under absorption costingCan obscure variable/fixed behaviour
EBITDAOperating cash-generation proxyIgnores capex, working capital, and debt service
Customer satisfactionService and retentionMust be measured consistently
Defect rate/reworkQuality controlLow defect rate may hide inspection failures
Employee turnoverWorkforce stabilityNeeds context: role, market, culture

Balanced Scorecard and KPI Selection

PerspectiveExample objectivesExample KPIs
FinancialImprove profitability, cash flow, cost controlOperating margin, contribution margin, cash conversion
CustomerImprove satisfaction and retentionNet promoter-type measures, complaints, retention
Internal processImprove efficiency and qualityCycle time, defect rate, on-time delivery
Learning and growthBuild capabilityTraining hours, employee engagement, turnover
Sustainability/community, if case-relevantAlign with stakeholder expectationsEmissions, safety incidents, community impact

Good KPIs are relevant, controllable, measurable, timely, comparable, and aligned with strategy. In a case, recommend a balanced set rather than only financial indicators.
