CPA Core 2 — Management Accounting Exam Blueprint

A practical CPA Core 2 exam blueprint for CPA Canada PEP Core 2 - Management Accounting, Planning, and Control candidates reviewing management accounting, planning, control, decision analysis, and performance topics.

How to Use This Exam Blueprint

This page is an independent study checklist for candidates preparing for CPA Canada PEP Core 2 - Management Accounting, Planning, and Control, exam code CPA Core 2. Use it to turn broad study areas into specific readiness tasks.

Work through the checklist in three passes:

  1. Coverage pass: Mark every topic as reviewed, weak, or not yet reviewed.
  2. Application pass: Practise explaining the issue, selecting the method, performing the calculation, and interpreting the result.
  3. Final-review pass: Focus on judgment errors, incomplete recommendations, missing qualitative factors, and calculation mechanics.

The goal is not to memorize isolated formulas. For CPA Core 2, readiness means you can read a business scenario, identify what management decision is being tested, choose the right analysis, perform enough quantitative work, and give a practical recommendation with limitations.

Core Management Accounting Foundations

Cost Classification Checklist

Be able to classify costs differently depending on the decision being made.

Cost typeReadiness questionTrap to avoid
Fixed costDoes the cost change within the relevant range?Treating all fixed costs as irrelevant; avoidable fixed costs may matter
Variable costDoes total cost change with activity?Assuming per-unit cost is constant outside the relevant range
Mixed costCan the cost be separated into fixed and variable components?Using total mixed cost without estimating behaviour
Direct costCan the cost be traced economically to the cost object?Confusing direct cost with relevant cost
Indirect costDoes the cost need allocation?Treating allocated overhead as automatically relevant
Sunk costHas the cost already been incurred or committed?Including sunk costs in future decisions
Opportunity costWhat benefit is sacrificed by choosing this option?Omitting capacity constraints or forgone contribution
Controllable costCan the manager influence the cost?Holding managers accountable for uncontrollable items

Can You Do This?

  • Separate fixed, variable, mixed, direct, indirect, controllable, and non-controllable costs.
  • Identify the relevant range and explain why it matters.
  • Remove sunk costs from a decision analysis.
  • Add opportunity costs when a constrained resource has an alternative use.
  • Explain why accounting profit and decision-relevant profit may differ.
  • State assumptions clearly when cost behaviour is uncertain.
  • Identify when allocated overhead distorts product or customer profitability.

Cost-Volume-Profit and Contribution Analysis

Key Formulas to Know

Contribution margin per unit:

\[ \text{Contribution margin per unit} = \text{Selling price per unit} - \text{Variable cost per unit} \]

Contribution margin ratio:

\[ \text{Contribution margin ratio} = \frac{\text{Contribution margin}}{\text{Sales}} \]

Break-even units:

\[ \text{Break-even units} = \frac{\text{Fixed costs}}{\text{Contribution margin per unit}} \]

Target profit units:

\[ \text{Units required} = \frac{\text{Fixed costs} + \text{Target profit}}{\text{Contribution margin per unit}} \]

Margin of safety:

\[ \text{Margin of safety} = \text{Actual or expected sales} - \text{Break-even sales} \]

Costing Systems and Overhead Allocation

Costing System Readiness Table

AreaWhat to reviewCan you apply it?
Job costingDirect materials, direct labour, overhead applied to jobs[ ]
Process costingEquivalent units, cost per equivalent unit, cost assignment[ ]
Activity-based costingActivities, cost drivers, cost pools, activity rates[ ]
Standard costingStandards for inputs, prices, rates, efficiency[ ]
Overhead allocationPredetermined rates, allocation bases, under/over-applied overhead[ ]
Customer/product profitabilityDirect costs, allocated support costs, activity consumption[ ]

Activity-Based Costing Checklist

  • Identify cost pools.
  • Select cost drivers that reflect resource consumption.
  • Calculate activity rates.
  • Assign costs to products, services, customers, or channels.
  • Compare ABC results to traditional allocation results.
  • Explain why high-volume products may be overcosted or undercosted.
  • Discuss implementation cost, data quality, and behavioural impact.

Common Costing Traps

TrapBetter approach
Using one overhead rate when products consume support activities differentlyConsider activity-based costing or multiple cost pools
Treating allocated fixed overhead as incrementalSeparate avoidable and unavoidable costs
Recommending a product discontinuance based only on full costAnalyze lost contribution and avoidable costs
Ignoring idle capacityConsider whether capacity has an alternative use
Overfocusing on calculation precisionInterpret what the costing result means for the decision

Budgeting, Forecasting, and Planning

Budgeting Topics to Review

TopicWhat to be ready for
Sales budgetVolume, price, seasonality, demand assumptions
Production or service capacity budgetRequired output, inventory policy, resource constraints
Direct materials budgetPurchases, usage, inventory needs, supplier constraints
Direct labour budgetHours, wage rates, scheduling, overtime
Overhead budgetVariable and fixed overhead behaviour
Selling and administrative budgetDiscretionary vs committed spending
Cash budgetCollections, disbursements, timing, financing needs
Flexible budgetBudget adjusted to actual activity level
Rolling forecastUpdated forward-looking planning
Sensitivity analysisImpact of changed assumptions

Budget Review Checklist

  • Do the budget assumptions match the business facts?
  • Are fixed and variable costs treated appropriately?
  • Are cash timing differences captured?
  • Are one-time items separated from recurring activity?
  • Are capacity constraints reflected?
  • Are growth assumptions realistic?
  • Are working capital needs considered?
  • Does the budget align with strategy?
  • Are risks and sensitivities discussed?
  • Are recommendations specific and actionable?

Decision Prompts

ScenarioWhat to evaluate
Budget shows profit but cash shortageReceivable timing, inventory purchases, payables, financing gap
Department exceeded budgetFlexible budget variance vs static budget comparison
Sales forecast is aggressiveMarket evidence, capacity, historical trends, sensitivity
Cost reduction target is imposedImpact on quality, staffing, customer service, long-term strategy
Manager builds slack into budgetEthics, incentives, transparency, performance measurement

Variance Analysis and Control

Variance Skills Checklist

Variance areaCan you calculate?Can you interpret?
Direct material price variance[ ][ ]
Direct material quantity variance[ ][ ]
Direct labour rate variance[ ][ ]
Direct labour efficiency variance[ ][ ]
Variable overhead spending variance[ ][ ]
Variable overhead efficiency variance[ ][ ]
Fixed overhead budget/spending variance[ ][ ]
Fixed overhead volume variance[ ][ ]
Sales price variance[ ][ ]
Sales volume variance[ ][ ]
Mix and yield effects, when relevant[ ][ ]

Interpretation Checklist

For every variance, be ready to answer:

  • Is the variance favourable or unfavourable?
  • Is it material enough to investigate?
  • Is it controllable by the manager being evaluated?
  • Is the cause price/rate, efficiency/usage, volume, mix, quality, timing, or external conditions?
  • Could a favourable variance indicate a problem, such as lower quality inputs?
  • Could an unfavourable variance be strategically acceptable?
  • What follow-up action should management take?

Common Variance Interpretation Traps

TrapWhy it is risky
Assuming favourable always means goodLower-cost materials may increase waste or returns
Investigating every small varianceControl systems should focus attention on meaningful issues
Blaming production for material price variancePurchasing, supplier conditions, or quality standards may be responsible
Blaming labour for efficiency variance without contextTraining, equipment, scheduling, and material quality may contribute
Ignoring sales mixTotal sales may look acceptable while product profitability deteriorates

Relevant Costing and Short-Term Decisions

Decision Analysis Table

Decision typeQuantitative focusQualitative factors
Make or buyAvoidable costs, purchase price, opportunity cost, capacity useSupplier reliability, quality, strategic control, confidentiality
Special orderIncremental revenue, incremental cost, capacity, price floorCustomer expectations, regular pricing impact, brand positioning
Drop or continue product/serviceLost contribution, avoidable fixed costs, common fixed costsCustomer relationships, bundled sales, strategic presence
Add or remove segmentSegment margin, avoidable costs, shared resourcesLong-term growth, employee impact, stakeholder reaction
Sell or process furtherAdditional revenue vs additional processing costQuality risk, market demand, capacity, waste
Scarce resource allocationContribution per constrained resource unitCustomer priorities, contractual obligations, strategic products
OutsourcingCost comparison, avoidable internal costs, transition costsDependency, quality, data/security, employee morale

Relevant Costing Readiness Checklist

  • Identify the decision alternatives.
  • Include only future costs and benefits that differ between alternatives.
  • Exclude sunk costs.
  • Separate avoidable from unavoidable fixed costs.
  • Include opportunity costs when resources are constrained.
  • Consider tax, cash flow, or working capital effects only when relevant and supported by the facts.
  • State non-financial factors.
  • Recommend an option and explain why.

Scarce Resource Formula

When one resource is constrained, prioritize by contribution per unit of scarce resource:

\[ \text{Contribution per scarce resource unit} = \frac{\text{Contribution margin per unit}}{\text{Scarce resource required per unit}} \]

Use this only after confirming that demand, capacity, and resource constraints are actually relevant.

Pricing, Profitability, and Customer Decisions

Pricing Readiness Areas

TopicWhat to know how to do
Cost-plus pricingCalculate markup on cost and explain limitations
Market-based pricingConsider competitors, customer value, demand, and positioning
Target costingWork backward from market price to allowable cost
Special pricingIdentify incremental cost and capacity constraints
Customer profitabilityInclude order frequency, support costs, returns, discounts, delivery, and service demands
Product lifecycleConsider introduction, growth, maturity, decline, and support costs
Price sensitivityDiscuss demand response and contribution impact

Pricing Decision Checklist

  • What is the objective: market share, profit, capacity use, strategic entry, retention, or cash flow?
  • Is there unused capacity?
  • What is the incremental cost floor?
  • What does the market or customer value suggest as a ceiling?
  • Will the price affect existing customers?
  • Are there channel, brand, or ethical issues?
  • Does the recommendation align with the organization’s strategy?

Transfer Pricing and Responsibility Centres

Transfer Pricing Checklist

AreaReadiness prompt
Market-based transfer priceIs there an external market price for the intermediate good or service?
Variable-cost transfer priceDoes it encourage internal transfers but understate supplying division performance?
Full-cost transfer priceDoes it recover cost but risk inefficient decisions?
Negotiated transfer priceDo both divisions have enough information and bargaining power?
Capacity constraintIs the supplying division at full capacity?
Opportunity costWhat external contribution is sacrificed by transferring internally?
Goal congruenceDoes the transfer price support total organization profit?
Performance evaluationAre divisional managers assessed fairly?

Responsibility Centre Readiness

Centre typeManager evaluated onCommon exam issue
Cost centreCosts, efficiency, service levelCutting cost may damage quality
Revenue centreRevenue generationRevenue growth may ignore profitability
Profit centreRevenues and costsAllocated costs may distort performance
Investment centreProfit relative to assets or investmentManagers may reject good projects due to metric incentives

Can You Explain?

  • Why a transfer price can be good for one division but bad for the organization.
  • Why controllability matters in performance evaluation.
  • How performance metrics can create dysfunctional behaviour.
  • When decentralization improves decision-making.
  • When head office intervention may be needed.

Performance Measurement and Management Control

Performance Measurement Checklist

TopicReview task
Financial KPIsMargin, profit, revenue growth, cost per unit, return measures, cash flow
Non-financial KPIsQuality, customer satisfaction, cycle time, defect rate, employee turnover
Balanced performance viewLink financial, customer, internal process, and learning/growth measures
Leading vs lagging indicatorsIdentify whether the measure predicts or reports performance
ControllabilityMatch measures to what managers can influence
BenchmarkingCompare to internal history, targets, competitors, or industry norms
IncentivesAssess whether compensation drives desired behaviour
Data qualityQuestion whether measures are reliable, timely, and complete

KPI Selection Prompts

For each KPI you recommend, be able to state:

  • What strategic objective does it support?
  • How is it measured?
  • Who is responsible for it?
  • Is it controllable?
  • Is it timely?
  • Can it be manipulated?
  • What behaviour might it encourage?
  • What complementary measure is needed to balance it?

Common Weak Area: Recommendations Without Measures

A common Core 2 weakness is recommending a strategy or operational change without explaining how management will monitor success.

A stronger response includes:

  • the recommended action;
  • the expected benefit;
  • one or more KPIs;
  • who should monitor them;
  • when management should reassess;
  • risks or limitations.

Strategy, Risk, and Operational Decision-Making

Strategy Connection Checklist

Even when the calculation is central, connect it to the business context.

Business factPossible management accounting implication
Premium brandAvoid cost cuts that reduce quality or customer experience
Low-cost strategyFocus on process efficiency, cost control, capacity utilization
Growth strategyConsider capacity, cash flow, working capital, scalability
Declining product lineEvaluate discontinuance, repositioning, or harvesting
Supply disruptionConsider outsourcing, supplier diversification, safety stock
Labour shortageReview automation, scheduling, training, overtime, productivity
Customer concentrationEvaluate pricing power, credit risk, service dependency
New technologyConsider implementation cost, learning curve, data reliability
Strong competitionEvaluate pricing, differentiation, cost structure, and margins

Risk and Control Checklist

  • Identify the business risk.
  • Explain the potential consequence.
  • Link the risk to the decision or control weakness.
  • Recommend a practical mitigation.
  • Consider cost-benefit of the control.
  • Avoid generic controls that do not address the fact pattern.
  • Consider who should be responsible for follow-up.

Control Recommendation Format

Use a concise structure:

ElementExample of what to include
Weakness“Budget approvals are not reviewed against capacity constraints.”
Risk“Management may approve sales targets that cannot be fulfilled.”
Recommendation“Require operations sign-off on volume assumptions before final budget approval.”
Benefit“This improves forecast reliability and reduces missed delivery commitments.”

Ethics and Professional Judgment

Ethical Readiness Checklist

Be ready to identify and respond to situations involving:

  • Budgetary slack or intentionally biased forecasts.
  • Manipulation of performance metrics.
  • Pressure to misclassify costs or defer expenses.
  • Incentive plans that reward short-term results at the expense of long-term value.
  • Selective presentation of favourable calculations.
  • Ignoring relevant qualitative risks.
  • Conflicts between divisional goals and organization-wide goals.
  • Recommendations that harm customers, employees, or stakeholders without proper consideration.

Professional Judgment Prompts

Ask yourself:

  • What would a reasonable decision-maker need to know?
  • Are assumptions transparent?
  • Is the analysis balanced?
  • Are limitations stated?
  • Is the recommendation supportable from both quantitative and qualitative evidence?
  • Have ethical and stakeholder concerns been addressed when relevant?
