What ACCTG 221 covers
Follow the course from cost behaviour and costing systems through planning, control, short-run decisions and performance measurement. Each chapter pairs the calculation with the management meaning and a fresh worked problem.
Cost-Volume-Profit and Sales Mix
Contribution margin, break-even, target profit, margin of safety and weighted sales mixCost-volume-profit analysis converts selling price, variable cost and fixed cost into a contribution model for planning. The core relationship is profit equals total contribution minus fixed cost.
- Contribution margin per unit and contribution margin ratio
- Break-even in units and sales dollars
- Target-profit volume and after-tax target reasoning
- Margin of safety and operating leverage
- Weighted sales mix and composite bundles
- Sensitivity to price, cost and mix changes
Cost Behaviour and Support Allocation
Cost functions, high-low estimates, step-down allocation and reciprocal servicesCost behaviour describes how total and per-unit costs respond within a relevant range. Variable cost is constant per unit while fixed cost is constant in total; mixed cost combines both.
- Variable, fixed, mixed and step cost patterns
- Relevant range and time horizon
- High-low estimation of a mixed cost
- Direct allocation to operating departments
- Step-down order and partial reciprocal recognition
- Simultaneous equations for reciprocal services
Job and Process Costing Systems
Job records, overhead rates, equivalent units and cost reconciliationJob costing accumulates direct material, direct labour and applied overhead for identifiable jobs. Process costing follows homogeneous output through departments and spreads cost across equivalent units.
- Job cost sheets and subsidiary records
- Predetermined overhead rates and applied overhead
- Underapplied and overapplied overhead
- Physical flow reconciliation in process costing
- Equivalent units for materials and conversion
- Weighted-average cost per equivalent unit
Process Costing with Spoilage
Weighted-average flows, inspection points, normal loss and abnormal lossSpoilage adds a loss stream to the ordinary process-cost flow. The inspection point determines which units can carry normal spoilage cost and whether ending work has reached the point where loss is detected.
- Inspection points and detected loss
- Normal versus abnormal spoilage
- Physical flow including spoiled units
- Equivalent units for lost output
- Allocation of normal spoilage cost
- Separate recognition of abnormal spoilage
Activity-Based Costing and Management
Activity pools, driver rates, cross-subsidy and process improvementActivity-based costing separates overhead into pools linked to activities and assigns each pool using a driver that reflects consumption.
- Activity pools and resource costs
- Cost drivers and driver volumes
- Two-stage assignment to cost objects
- Cross-subsidy under broad averages
- Activity-based management and process redesign
- Implementation cost and behavioural limits
Ethics, Culture and Planning Decisions
Ethical reasoning, organisational culture, planning assumptions and control effectsManagement accounting choices affect people as well as reported numbers. Ethical analysis begins by identifying facts, affected parties, duties and feasible alternatives, then tests consequences and documents a defensible action.
- Facts, stakeholders and competing duties
- Ethical alternatives and consequence testing
- Professional escalation and documentation
- Culture, incentives and psychological safety
- Budget participation and budget slack
- Planning assumptions and control feedback
Master, Cash and Purchases Budgets
Linked operating budgets, collection timing, inventory policy and cash needsThe master budget is a linked model rather than a collection of independent schedules. Sales drive production or purchases; inventory policy connects one period with the next; timing assumptions turn sales and purchases into cash collections and payments.
- Sales budget as the operating driver
- Production and purchases equations
- Desired ending inventory policy
- Cash collection and payment timing
- Cash budget and financing requirement
- Schedule links and spreadsheet audit checks
Flexible Budgets and Variance Analysis
Activity adjustment, price and efficiency bridges, reconciliation and investigationA flexible budget restates standard revenue and cost for actual output, allowing fair comparison with actual results. Static-to-flexible differences describe volume, while actual-to-flexible differences describe price, rate, usage or efficiency.
- Static versus flexible budgets
- Standard quantity allowed for actual output
- Price and rate variances
- Usage and efficiency variances
- Variable and fixed overhead variances
- Variance reconciliation and cause investigation
Relevant Costing and Short-Run Decisions
Differential cash flows, capacity, opportunity cost and scarce-resource choicesShort-run decisions compare future amounts that differ between alternatives. Sunk cost and unavoidable allocated fixed cost are excluded even when they appear in a product-cost report.
- Future and differential information
- Sunk and unavoidable costs
- Special orders under spare or full capacity
- Keep-or-drop and avoidable fixed cost
- Make-or-buy and supplier effects
- Contribution per scarce-resource unit
Balanced Scorecard and Performance Measures
Strategy maps, lead and lag measures, responsibility and behavioural effectsA balanced scorecard translates strategy into linked objectives and measures across financial, customer, internal-process, and learning and growth perspectives.
- Four balanced-scorecard perspectives
- Strategy maps and causal hypotheses
- Lead and lag indicators
- Financial and non-financial measures
- Responsibility and controllability
- Gaming, data quality and review
The second half links planning and control: master budgets translate an operating plan into sales, production, purchases and cash schedules; flexible budgets separate volume effects from spending and efficiency effects; relevant costing identifies future differences between alternatives; and balanced scorecards connect operational drivers with later financial outcomes.
The calculations are cumulative, but the recurring discipline is stable. Define the decision, identify the cost object or activity, preserve units, reconcile totals and explain what the number means for action. Current assessment gives 10% to Turn-ins and Self-reviews, 20% to the Assignment, 20% to the Test and 50% to the Final Exam.
The captured final announcement specifies an in-person Inspera examination in Mode D, with a calculator and up to five double-sided A4 sheets, for two hours plus separate reading and technology time. That makes this guide useful in two ways: as a worked calculation book during the teaching weeks and as a compact map for final revision. Every worked problem here uses fresh businesses and numbers.
Use the examples to learn the method, then close the solution and rebuild the calculation from the decision question, the units and the reconciliation.

Worked example · free
Harbour Lamps: break-even and target profit
- +1Contribution per lamp = $58 minus $40 = $18.
- +2Break-even volume = $72,000 divided by $18 = 4,000 lamps.
- +2Target-profit volume = ($72,000 + $27,000) divided by $18 = 5,500 lamps.
- +2Margin of safety = 6,000 minus 4,000 = 2,000 lamps, or 33.3% of expected sales.

ACCTG 221 FAQ
How is ACCTG 221 assessed?
Current Canvas materials allocate 10% to Turn-ins and Self-reviews, 20% to the Assignment, 20% to the Test and 50% to the Final Exam. The four numeric rows total 100%, and the captured materials do not state a separate component hurdle.
What is the semester test like?
The current test document specifies one hour plus fifteen minutes of reading time, 60 marks and three questions. It describes approximately 15% short-answer work and 85% calculation work, so clear workings and time allocation matter alongside the final number.
What is the final exam mode?
The later current announcement specifies an in-person Inspera examination in Mode D. It allows a calculator and up to five double-sided A4 sheets, and gives two hours plus separate reading and technology time. Follow the live announcement if operational details change.
Which calculations should I practise first?
Start with contribution margin and break-even, overhead allocation, equivalent units, linked budgets, variance bridges and relevant-cost tables. These families reward a consistent setup: label units, write the governing relationship, calculate line by line and reconcile the result to a total.
Is the assignment only about getting formulas right?
No. The assignment instructions split attention between correctness and the quality of spreadsheet design, usability and communication. A technically correct model can still be hard to audit, so use labelled inputs, visible formulas, logical schedules and checks that expose broken links.
How should I use the allowed notes?
Build notes around decision patterns rather than copying long explanations. Include the formula, the unit of every input, a short sign convention, one reconciliation and the qualitative question that follows. Practise with the same sheets so navigation is automatic before the final.
What makes the course difficult?
The captured assessment facts show a heavily weighted final and a test dominated by calculations. The challenge is cumulative accuracy: a wrong unit, denominator or capacity assumption can flow through several marks. Regular fresh-number practice is more effective than rereading completed solutions.
Questions students ask in each ACCTG 221 chapter
- Why does break-even use contribution rather than revenue?
- Revenue must first recover the variable cost caused by each sale. Only the remainder, contribution margin, is available for fixed cost. Dividing fixed cost by revenue would ignore that necessary outflow and understate the required volume. Chapter 01 · Cost-Volume-Profit and Sales Mix
- Why can fixed cost per unit change?
- Fixed cost is constant in total within the relevant range, so dividing it over more units reduces the amount per unit. That arithmetic change does not mean the total fixed resource cost became variable. Chapter 02 · Cost Behaviour and Support Allocation
- When is job costing appropriate?
- Use job costing when outputs are distinguishable and costs can be traced to individual contracts, batches or services. A custom project normally needs its own cost record, whereas continuous homogeneous production points toward process costing. Chapter 03 · Job and Process Costing Systems
- Why does the inspection point matter?
- A unit must reach the inspection point before its spoilage can be detected. Ending work that has not reached that point cannot normally bear detected loss, while units passing the point may share normal spoilage cost. Chapter 04 · Process Costing with Spoilage
- Does ABC reduce total overhead?
- No. Changing the assignment method redistributes the same overhead pools unless management also changes the underlying activities. Always prove that product or customer allocations add back to the total pool cost. Chapter 05 · Activity-Based Costing and Management
- Why is this topic part of management accounting?
- Budgets, allocations and performance measures influence rewards, workload and reported success. Their design can create pressure to distort assumptions or defer necessary action, so technical competence includes recognising and responding to those incentives. Chapter 06 · Ethics, Culture and Planning Decisions
- Why can a profitable budget need borrowing?
- Profit recognises revenue and expense under accrual timing, while cash depends on collection and payment dates. Rapid growth can require inventory and supplier payments before customers settle their accounts. Chapter 07 · Master, Cash and Purchases Budgets
- Why not compare actual cost only with the static budget?
- That comparison mixes the cost effect of producing a different volume with the effect of paying or using inputs differently. A flexible budget first restates the benchmark for actual output. Chapter 08 · Flexible Budgets and Variance Analysis
- Why are allocated fixed costs often irrelevant?
- An accounting allocation can remain after a product or department is removed. Only the portion that actually disappears, or changes under another alternative, belongs in the decision table. Chapter 09 · Relevant Costing and Short-Run Decisions
- Why are financial measures not enough?
- Financial results are important but often lag the operational causes of performance. Process, customer and capability measures can signal whether the strategy is being executed before the final financial outcome appears. Chapter 10 · Balanced Scorecard and Performance Measures
How to study for the exam
Use a three-pass weekly routine. First, make a one-page map of the new decision: the object being costed, the governing relationship, the units and the reconciliation. Second, work a fresh numerical problem without looking at a completed solution. Mark each line as setup, substitution, arithmetic, proof or interpretation so errors become diagnosable.
Third, explain the managerial implication in one sentence and name one qualitative factor. Before the test, practise three-question sets under the published time structure and reserve minutes for checking totals. Before the final, organise the permitted sheets by decision family: cost behaviour and CVP; costing systems and allocation; budgets and variances; relevant decisions and performance.
Put compact examples beside formulas because a formula without its denominator is easy to misuse. For every answer, preserve a visible audit trail, state favourable or unfavourable only after checking the cost or revenue context, and reconcile component amounts to the overall difference. Use the final review to revisit errors, not questions already mastered.
