EMAC3714: Management Accounting Key Concepts – Exam Study Guide (UFS BAcc)

Management Accounting for EMAC3714 (often cross‑searched with terms like “EMAC3714 exam notes UFS,” “management accounting 3B study notes,” and “BAcc UFS management accounting key concepts”) centers on using accounting information for internal decision‑making. This guide is designed for University of the Free State (UFS) BAcc students but is also helpful to students searching for Unisa MNB3702‑style management topics or CUT cost accounting concepts. It focuses on the core EMAC3714 outcomes: cost classification, cost‑volume‑profit (CVP) analysis, relevant costing, budgeting, and performance measurement.

The emphasis throughout is on exam‑style understanding: clear definitions, structured calculations, and interpretation of results. Numerical examples and mini case studies mirror the level of detail typically expected in a third‑year management accounting module such as EMAC3714 in the UFS BAcc programme.

1. Role and Scope of Management Accounting in EMAC3714

Management accounting within EMAC3714 is about providing useful information for internal planning, decision‑making, and control. Unlike financial accounting (which is externally focused and rules‑based), management accounting is flexible and tailored to managers’ needs.

1.1 Management Accounting vs Financial Accounting

A clear contrast between management accounting and financial accounting is a favourite exam starting point. Be able to compare the two across several dimensions:

Aspect	Management Accounting (EMAC3714 focus)	Financial Accounting (e.g. FRK modules)
Primary users	Internal managers at UFS case firms	External users (shareholders, creditors, SARS)
Main purpose	Planning, decision‑making, control	Reporting financial performance and position
Time orientation	Future‑oriented (budgets, forecasts)	Past‑oriented (historical financial statements)
Regulations	No mandatory format; internal policies	IFRS / GAAP and Companies Act requirements
Level of detail	Very detailed, segment/product‑level	Aggregated for the entity as a whole
Frequency	As needed (daily, weekly, monthly reports)	Periodic (usually annually, sometimes quarterly)
Nature of information	Both financial and non‑financial (e.g. units, hours, KPIs)	Primarily financial in rand terms

In EMAC3714, the exam often tests how specific management accounting tools (e.g. CVP analysis, budgets, variance analysis) help managers at a hypothetical company, such as a Bloemfontein‑based manufacturing firm, make better decisions.

1.2 Core Functions: Planning, Control and Decision‑Making

Management accounting supports three broad managerial functions, which directly map onto EMAC3714 syllabus themes.

Planning
Involves setting objectives and deciding how to achieve them.
- Preparing budgets (sales, production, cash budgets).
- Conducting CVP analysis to assess how sales volumes affect profit.
- Performing capital budgeting (although often covered more in finance modules, EMAC3714 may touch on simple payback, NPV concepts).
Control
Ensures performance aligns with plans.
- Comparing actual results with budgeted results.
- Identifying variances and analyzing their causes.
- Implementing corrective actions (e.g. tightening cost control, adjusting selling prices).
Decision‑Making
Choosing among alternatives using relevant costs and revenues.
- Make‑or‑buy decisions.
- Special order decisions.
- Product mix under limiting factors.
- Discontinuation of a product or department.

In EMAC3714, questions frequently integrate these functions, for example: “Given the following budget and cost behavior, evaluate whether UFS Textiles (Pty) Ltd should accept a special order at a reduced price.”

1.3 Types of Management Accounting Reports

Management accounting outputs information in different report formats, often customized to a specific manager or decision.

Common report types include:

Cost reports by cost centre
For example, a manufacturing company near UFS may have separate reports for the cutting, assembly, and finishing departments. These detail:
- Direct materials used.
- Direct labour hours and wages.
- Overhead costs (e.g. factory rent, maintenance).
Responsibility reports
Linked to responsibility accounting (covered more deeply in performance measurement):
- Cost centre reports: compare controllable costs to budget.
- Profit centre reports: show revenue, costs, and profit by division.
- Investment centre reports: include ROI and residual income calculations.
Budget reports
- Sales vs budgeted sales by product.
- Cash flows vs forecast.
- Capital expenditure tracking vs approval.
Decision‑specific reports
Prepared as needed, such as:
- “Analysis of relevant costs for proposed shutdown of Plant B.”
- “Incremental profit from accepting a 10,000‑unit export order.”

In EMAC3714, you may be asked to draft the structure (headings) of a report, interpret a given report, or perform calculations and then comment on the implications for management.

1.4 Ethical Considerations in Management Accounting

The UFS BAcc curriculum (including EMAC3714) emphasizes ethics, aligning with SAICA and international codes. Expect theory questions on ethical issues:

Key principles relevant to management accountants:

Integrity – be honest and straightforward in all professional and business relationships.
Objectivity – do not allow bias, conflict of interest, or undue influence.
Professional competence and due care – maintain professional knowledge and skill; act diligently.
Confidentiality – do not disclose information without proper authority.
Professional behavior – comply with relevant laws and avoid actions discrediting the profession.

Typical exam‑style ethical scenarios:

A management accountant at “Bloem Furniture Ltd” is pressured to under‑allocate overheads to certain products to make them appear more profitable.
A divisional manager at “Free State Textiles” asks the accountant to delay recognizing certain expenses until after year‑end to improve bonus‑related performance measures.

In answering such questions, identify the ethical principles involved, explain why the behaviour is inappropriate, and propose a professional response (e.g. refusing to manipulate figures, documenting concerns, escalating the issue to higher authority, or consulting a professional body).

2. Cost Concepts and Cost Classification

EMAC3714 assumes a solid command of cost terminology. Precise definitions and correct classification are frequently tested, especially early in the paper, and they underpin CVP, budgeting, and decision‑making topics.

2.1 Basic Cost Terminology

Cost: The monetary value of resources sacrificed or forgone to achieve a specific objective (e.g. producing a unit, providing a service).

Common cost terms in EMAC3714:

Direct material (DM) – Raw materials that can be physically and conveniently traced to a finished product.
- Example: Fabric in UFS Sportswear’s tracksuits.
Direct labour (DL) – Wages for workers who can be directly traced to specific units of output.
- Example: Sewing machine operators in the garment line.
Prime cost – Direct materials + Direct labour.
Manufacturing overhead (MOH) – All manufacturing costs other than direct materials and direct labour.
- Example: Factory rent, factory supervisor’s salary, factory electricity.
Conversion cost – Direct labour + Manufacturing overhead.
- Converts raw materials into finished goods.

Example: Calculating prime and conversion costs

UFS Furniture Ltd produces chairs and reports the following monthly costs:

Direct materials: R120,000
Direct labour: R80,000
Factory rent: R50,000
Factory utilities: R20,000

Then:

Prime cost = DM + DL = R120,000 + R80,000 = R200,000
Manufacturing overhead = R50,000 + R20,000 = R70,000
Conversion cost = DL + MOH = R80,000 + R70,000 = R150,000

Prime cost focuses on traceable production costs, while conversion cost focuses on resources used to transform materials.

2.2 Product vs Period Costs

This classification affects how costs are treated in costing systems and CVP calculations.

Product costs
- Costs assigned to goods that are manufactured or purchased for resale.
- Include: Direct materials, Direct labour, Manufacturing overhead.
- Capitalized as inventory on the balance sheet until goods are sold, then expensed as Cost of Sales.
Period costs
- Costs expensed in the period incurred.
- Typically selling, distribution, and administrative expenses.
- Examples: Office salaries, advertising, head office rent.

Example: UFS Textiles Ltd

Monthly costs:

Fabric and thread: R200,000
Sewing machine operators’ wages: R150,000
Factory rent: R60,000
Advertising: R30,000
Office salaries: R40,000

Product costs total:

DM (R200,000) + DL (R150,000) + MOH (R60,000) = R410,000

Period costs total:

Advertising (R30,000) + Office salaries (R40,000) = R70,000

In EMAC3714, you may be required to separate a list of mixed items into product vs period costs, then calculate inventory values or cost per unit.

2.3 Fixed, Variable, Mixed, and Step Costs

Understanding cost behaviour is crucial for CVP analysis and flexible budgeting.

Variable costs
- Change in total in direct proportion to changes in activity level.
- Cost per unit remains constant within the relevant range.
- Example: Direct materials of R50 per unit. If 1,000 units are produced, total DM = R50,000; if 2,000 units: R100,000.
Fixed costs
- Remain constant in total within the relevant range, regardless of activity level.
- Cost per unit decreases as activity increases.
- Example: Factory rent of R100,000 per month, regardless of units produced.
Mixed (semi‑variable) costs
- Contain both fixed and variable components.
- Example: Telephone costs with a fixed line rental plus a charge per minute.
Step (semi‑fixed) costs
- Remain fixed over a certain activity range but jump to a new level when activity exceeds that range.
- Example: One supervisor can oversee up to 10 workers. Hiring an additional supervisor when there are more than 10 workers creates a step cost.

Example: Mixed cost separation using the high‑low method

UFS Logistics’ electricity costs in a factory:

At 5,000 machine hours, electricity costs R40,000.
At 8,000 machine hours, electricity costs R52,000.

Steps:

Calculate variable cost per unit of activity:
- Change in cost = R52,000 – R40,000 = R12,000
- Change in hours = 8,000 – 5,000 = 3,000 hours
- Variable cost per hour = R12,000 / 3,000 = R4 per hour
Determine fixed cost using one data point:
- Total cost = Fixed cost + (Variable cost per hour × hours)
- R40,000 = Fixed + (R4 × 5,000) = Fixed + R20,000
- Fixed cost = R40,000 – R20,000 = R20,000

Thus, total electricity cost = R20,000 + (R4 × machine hours).

Questions in EMAC3714 often give you a mixed cost and require separation using high‑low or regression (if included), then use the resulting fixed and variable components in budgeting and CVP.

2.4 Direct vs Indirect Costs; Cost Objects

A cost object is any activity, product, or segment for which cost information is desired (e.g. a specific product line such as “UFS Premium Jerseys”).

Direct cost – Can be directly traced in a cost‑effective way to a specific cost object.
Indirect cost – Cannot be traced easily; must be allocated (e.g. factory overheads to products).

Examples:

For UFS Premium Jerseys:
- Direct costs: Jersey fabric, cutting and sewing labour.
- Indirect costs: Factory rent, factory manager’s salary, canteen costs.

Incorrect classification can distort product costs and lead to poor pricing and product mix decisions—issues that often appear in exam scenarios.

2.5 Opportunity, Sunk, and Relevant Costs

Key for EMAC3714 decision‑making questions.

Sunk cost
- A past cost that has already been incurred and cannot be changed now or in the future.
- Irrelevant for decision‑making.
- Example: R300,000 spent two years ago on a machine that has no alternative use; its historical cost is sunk.
Opportunity cost
- The benefit forgone by choosing one alternative over another.
- Example: If a production line could produce either Product A (profit R50,000) or Product B (profit R60,000), the opportunity cost of choosing A is the R60,000 profit from B.
Relevant costs
- Future cash flows that differ between alternatives.
- Include differential costs, opportunity costs.
- Exclude sunk costs and any future costs that will be the same under all alternatives.

Example: Make‑or‑buy decision (Preview)

Suppose UFS Components makes a part with the following per‑unit data:

Direct material: R30
Direct labour: R20
Variable overhead: R10
Fixed overhead (allocated): R15
Total cost per unit: R75
Units required: 10,000 per year
An outside supplier offers the part at R65 per unit. Fixed overhead of R100,000 will continue regardless of the decision; the remaining R50,000 of fixed overhead is avoidable if the part is bought.

Relevant cost per unit of making:

Direct material: R30
Direct labour: R20
Variable overhead: R10
Avoidable fixed overhead per unit: R50,000 / 10,000 = R5
Relevant cost per unit to make = R65

Relevant cost per unit to buy = R65.

Thus, there is no financial difference (ignoring qualitative factors). However, if the supplier price were R62, the company should buy (R62 < R65 relevant cost to make). EMAC3714 exam questions require you to distinguish total cost information from relevant cost information.

3. Cost–Volume–Profit (CVP) Analysis and Break‑Even

CVP analysis, a central EMAC3714 topic, examines how changes in sales volume, prices, and costs impact profit. Break‑even analysis and contribution margin calculations appear frequently in calculations and multiple‑choice questions.

3.1 Contribution Margin Concepts

Contribution margin (CM) is the difference between sales and variable costs:

Total CM = Total Sales – Total Variable Costs
CM per unit = Selling price per unit – Variable cost per unit
CM ratio (or C/S ratio) = Contribution margin / Sales

Contribution margin contributes first to covering fixed costs and then to profit.

Example: Single product CVP

UFS Sportswear sells a hoodie:

Selling price per unit (SP): R400
Variable manufacturing cost per unit: R220
Variable selling cost per unit: R30
Total variable cost per unit: R250
Fixed manufacturing overhead per month: R150,000
Fixed selling and administrative per month: R50,000
Total fixed costs: R200,000

Calculations:

CM per unit = SP – Variable cost = R400 – R250 = R150
CM ratio = CM per unit / SP = R150 / R400 = 0.375 (37.5%)

If 2,000 hoodies are sold:

Total CM = 2,000 × R150 = R300,000
Profit = Total CM – Fixed costs = R300,000 – R200,000 = R100,000

Note how contributions cover fixed costs before yielding profit.

3.2 Break‑Even Point (BEP) and Target Profit

The break‑even point is the level of sales where profit is zero (total revenue = total costs). At BEP, total contribution margin equals fixed costs.

For a single product:

Break‑even units = Fixed costs / Contribution margin per unit
Break‑even sales in rand = Fixed costs / CM ratio

Using UFS Sportswear hoodie example:

Fixed costs = R200,000
CM per unit = R150
CM ratio = 37.5%

Break‑even units:

= R200,000 / R150 ≈ 1,333.33 units
In practice, round up to 1,334 hoodies.

Break‑even sales in rand:

= R200,000 / 0.375 ≈ R533,333.33
Round to R533,334.

Target profit calculations extend the same idea:

Required sales units = (Fixed costs + Target profit) / CM per unit
Required sales in rand = (Fixed costs + Target profit) / CM ratio

If UFS Sportswear wants a monthly profit of R180,000:

Required units:

(R200,000 + R180,000) / R150 = R380,000 / R150 ≈ 2,533.33 units
Round up to 2,534 hoodies.

Required sales in rand:

(R200,000 + R180,000) / 0.375 = R380,000 / 0.375 ≈ R1,013,333.33
Round to R1,013,334.

EMAC3714 exam questions often require you to calculate BEP, target profit units, and interpret whether given sales forecasts are adequate.

3.3 Margin of Safety and Operating Leverage

Margin of safety (MOS) measures how much sales can drop before the firm reaches break‑even.

MOS (units) = Actual (or budgeted) sales units – Break‑even units
MOS (rand) = Actual (or budgeted) sales – Break‑even sales
MOS (%) = MOS (rand) / Actual (or budgeted) sales

Using the hoodie example, assume UFS Sportswear budgets to sell 3,000 hoodies per month.

Budgeted sales in rand = 3,000 × R400 = R1,200,000
BEP sales = R533,334

MOS (rand):

= R1,200,000 – R533,334 = R666,666

MOS (%) = R666,666 / R1,200,000 ≈ 55.6%

A high margin of safety indicates lower risk of loss; EMAC3714 questions often ask you to interpret this in words.

Operating leverage measures how sensitive profit is to percentage changes in sales, given a particular cost structure.

Degree of operating leverage (DOL) = Contribution margin / Profit

Using UFS Sportswear at 3,000 units:

Total CM = 3,000 × R150 = R450,000
Profit = Total CM – Fixed costs = R450,000 – R200,000 = R250,000
DOL = R450,000 / R250,000 = 1.8

Interpretation: A 10% increase in sales results in approximately an 18% increase in profit (10% × 1.8), assuming the cost structure and selling price remain constant.

Exam questions may ask you to compare two companies: one with high fixed costs and high CM (high DOL) and one with lower fixed costs and lower CM (low DOL). You must explain which is riskier and why.

3.4 Multi‑Product CVP and Sales Mix

Many EMAC3714 case studies involve multiple products. The sales mix – relative proportion of each product sold – is critical because each product may have a different contribution margin.

The approach:

Determine the expected sales mix (e.g. 3:2 for Product A:Product B).
Calculate CM per unit for each product.
Compute weighted average CM per unit or weighted CM ratio.
Use the weighted CM in the usual BEP and target profit formulas.

Example: UFS Footwear – two products

UFS Footwear sells shoes:

Product A: Running shoes
- SP = R800, VC = R500 → CM = R300 per unit
Product B: Casual shoes
- SP = R600, VC = R360 → CM = R240 per unit
Fixed costs: R540,000 per month
Expected sales mix by units: A:B = 2:3

Step 1: Assume a bundle of 5 units (2 As, 3 Bs) to represent the mix.

Step 2: CM per bundle:

A: 2 × R300 = R600
B: 3 × R240 = R720
Total CM per 5‑unit bundle = R600 + R720 = R1,320

Step 3: Break‑even bundles:

= Fixed costs / CM per bundle = R540,000 / R1,320 ≈ 409.09 bundles
Round up to 410 bundles.

Step 4: Convert bundles to units:

Product A units at BEP = 410 × 2 = 820 units
Product B units at BEP = 410 × 3 = 1,230 units

Total BEP units: 820 + 1,230 = 2,050.

Sales in rand at BEP:

A: 820 × R800 = R656,000
B: 1,230 × R600 = R738,000
Total BEP sales = R656,000 + R738,000 = R1,394,000

EMAC3714 questions may vary the mix, then ask how BEP changes. A more profitable mix (more of the high‑CM product) reduces BEP.

3.5 CVP Assumptions and Limitations

Important theory component: CVP analysis rests on simplifying assumptions. In exams, you may be asked to list and explain these.

Key assumptions:

Linear revenue and cost behaviour within the relevant range:
- Selling price per unit is constant.
- Variable cost per unit is constant.
- Total fixed costs remain constant.
Single product or constant sales mix in multi‑product settings.
Units produced equal units sold (no significant change in inventory).
Relevant range applies – CVP analysis is valid only within a certain activity range.
Costs are segregable into fixed and variable components; no complexities such as complexity‑based non‑linearity.

Limitations:

In reality, quantity discounts, learning curves, capacity constraints, and mixed costs complicate the picture.
At very high activity levels, additional fixed costs may be incurred (e.g. new factory); at very low levels, some fixed costs may be reduced.

In discussing limitations, it is important to emphasize that CVP is still a powerful planning tool, but results must be interpreted with an understanding of these simplifying assumptions.

4. Budgeting and Standard Costing in EMAC3714

Budgeting is central to EMAC3714’s planning and control outcomes. Standard costing and variance analysis form the link between planned and actual performance. Together, they provide a framework for responsibility accounting and performance evaluation.

4.1 Purposes and Types of Budgets

Budget: A detailed quantitative plan for acquiring and using financial and other resources over a specified period, often one year.

Purposes of budgeting:

Planning – Forecasting future operations (sales, production, cash).
Coordination – Aligning the activities of different departments (e.g. sales and production).
Communication – Clarifying expectations and objectives.
Control – Providing a benchmark for comparing actual performance.
Motivation – Setting targets that influence behavior and effort.

Common types of budgets covered in EMAC3714:

Operating budgets
- Sales budget
- Production budget
- Direct materials usage and purchases budgets
- Direct labour budget
- Manufacturing overhead budget
- Selling and administrative expense budget
- Budgeted income statement
Financial budgets
- Cash budget
- Budgeted statement of financial position
- Capital expenditure budget (often cross‑referenced with finance modules)

4.2 The Master Budget – An Integrated Example

A popular exam question is constructing, analyzing, or interpreting a master budget, which is the set of interrelated budgets for a particular period.

Consider “UFS Plastics (Pty) Ltd” making a single product: plastic containers.

Assumptions for Quarter 1:

Budgeted sales (units):
- January: 10,000
- February: 12,000
- March: 15,000
Selling price: R50 per unit.
Finished goods inventory policy: End inventory = 20% of next month’s sales.
Beginning finished goods inventory for January: 2,000 units.
Direct material usage: 2 kg per unit.
Direct material cost: R5 per kg.
Ending direct material inventory policy: 10% of next month’s production needs.
Beginning material inventory: 4,000 kg.
Direct labour: 0.5 hours per unit at R60 per hour.
Variable overhead: R8 per unit produced.
Fixed overhead: R100,000 per quarter.
Variable selling costs: R4 per unit sold.
Fixed selling and admin: R50,000 per month.

Step 1: Sales Budget

Compute sales in units and rand.

Month	Units	Selling Price (R)	Sales (R)
January	10,000	50	500,000
February	12,000	50	600,000
March	15,000	50	750,000
Total	37,000		1,850,000

Step 2: Production Budget

Production (units) = Sales + Desired ending inventory – Beginning inventory.

Desired ending inventories:

Jan ending FG = 20% of Feb sales = 0.2 × 12,000 = 2,400
Feb ending FG = 20% of Mar sales = 0.2 × 15,000 = 3,000
Mar ending FG = 20% of Apr sales. If April’s sales are expected to be 16,000 units, then ending FG = 0.2 × 16,000 = 3,200.

Production budget:

Month	Sales	+ Ending FG	– Beginning FG	Production
Jan	10,000	2,400	2,000	10,400
Feb	12,000	3,000	2,400	12,600
Mar	15,000	3,200	3,000	15,200
Total	37,000	8,600	7,400	38,200

Step 3: Direct Materials Usage and Purchases Budgets

Direct materials needed for production:

Each unit requires 2 kg → Materials for production = Units × 2 kg.

Month	Production	DM per unit (kg)	DM needed (kg)
Jan	10,400	2	20,800
Feb	12,600	2	25,200
Mar	15,200	2	30,400
Total	38,200		76,400

Desired ending inventories of DM:

Jan ending DM = 10% of Feb needs = 0.10 × 25,200 = 2,520 kg
Feb ending DM = 10% of Mar needs = 0.10 × 30,400 = 3,040 kg
Mar ending DM = 10% of Apr needs. Assume April production is 16,200 units (tying to April sales and inventory policies), then April materials need = 16,200 × 2 = 32,400 kg; thus Mar ending DM = 0.10 × 32,400 = 3,240 kg.

DM purchases (kg) = DM needed for production + Desired ending DM – Beginning DM.

Month	DM needed (kg)	+ Ending DM (kg)	– Beginning DM (kg)	Purchases (kg)
Jan	20,800	2,520	4,000	19,320
Feb	25,200	3,040	2,520	25,720
Mar	30,400	3,240	3,040	30,600
Total	76,400	8,800	9,560	75,640

Cost of DM purchases:

DM price = R5 per kg.

Month	Purchases (kg)	Price per kg (R)	DM Purchases (R)
Jan	19,320	5	96,600
Feb	25,720	5	128,600
Mar	30,600	5	153,000
Total	75,640		378,200

Step 4: Direct Labour Budget

0.5 hours per unit at R60 per hour.

Month	Production (units)	Hours per unit	Total hours	DL Rate (R)	DL Cost (R)
Jan	10,400	0.5	5,200	60	312,000
Feb	12,600	0.5	6,300	60	378,000
Mar	15,200	0.5	7,600	60	456,000
Total	38,200		19,100		1,146,000

Step 5: Manufacturing Overhead Budget

Variable overhead = R8 per unit produced.
Fixed overhead = R100,000 per quarter (spread evenly or as specified; assume entire R100,000 in Q1).

Variable overhead:

Jan: 10,400 × R8 = R83,200
Feb: 12,600 × R8 = R100,800
Mar: 15,200 × R8 = R121,600
Total variable overhead = R305,600.

Total manufacturing overhead for Q1 = R305,600 + R100,000 = R405,600.

In exams, you may be asked to derive a budgeted manufacturing cost per unit:

DM cost per unit: 2 kg × R5 = R10
DL cost per unit: 0.5 hr × R60 = R30
Variable OH per unit: R8
Fixed OH per unit (using budgeted production of 38,200 units): R100,000 / 38,200 ≈ R2.62
Total manufacturing cost per unit ≈ R10 + R30 + R8 + R2.62 = R50.62

4.3 Cash Budget – Liquidity Planning

The cash budget tracks expected cash receipts and payments to ensure the business can meet its obligations.

Key components:

Cash receipts:
- Cash sales.
- Collections from credit sales (consider collection patterns).
- Other inflows (loan receipts, asset sales).
Cash payments:
- Payments to suppliers.
- Wages and salaries.
- Overheads (excluding non‑cash items like depreciation).
- Capital expenditure.
- Loan repayments, interest.
- Dividends.

Exam tips:

Pay close attention to timing differences between when a transaction occurs and when cash is received or paid.
Always separate profitability from liquidity: a profitable budgeted income statement does not guarantee positive cash flow.

EMAC3714 questions may give you collection and payment percentages, then require a month‑by‑month cash budget and identification of any financing needs.

4.4 Fixed vs Flexible Budgets

A fixed (static) budget is prepared for a single level of activity (e.g. original planned sales of 10,000 units). A flexible budget adjusts budgeted costs to the actual level of activity.

Flexible budgeting is crucial for variance analysis: comparing like with like.

Example:

UFS Components expected to produce 5,000 units, but actually produced 5,500 units. Variable overheads should increase with volume; fixed overheads should not.

Fixed budget (5,000 units):
- Variable OH: R20 per unit → 5,000 × R20 = R100,000
- Fixed OH: R150,000
- Total OH: R250,000
Flexible budget (5,500 units):
- Variable OH: 5,500 × R20 = R110,000
- Fixed OH: R150,000
- Total OH: R260,000

If actual OH was R270,000, the overhead spending variance is R270,000 – R260,000 = R10,000 unfavourable.

In EMAC3714, exam questions may ask you to:

Prepare a flexible budget for actual output.
Compute variances between actual and flexible budget.
Analyze which variances are due to activity level changes and which are due to cost control.

4.5 Standard Costing and Variance Analysis

Standard costs are predetermined unit costs (DM, DL, OH) that should be incurred under efficient operating conditions. They provide the benchmark for evaluating actual costs.

Types of standards:

Ideal (perfection) standards – assume perfect efficiency, no wastage; rarely used for performance evaluation.
Currently attainable standards – assume efficient levels, allowing for normal wastage; commonly used.

EMAC3714 focuses on calculating and interpreting variances:

Direct material price variance.
Direct material usage (quantity) variance.
Direct labour rate variance.
Direct labour efficiency variance.
Variable overhead spending and efficiency variances (if in syllabus).
Fixed overhead budget and volume variances (sometimes included).

4.5.1 Direct Materials Variances

Let:

SP = Standard price per unit (e.g. per kg).
AP = Actual price per unit.
SQ = Standard quantity allowed for actual output.
AQ = Actual quantity used.

Formulas:

Materials price variance (MPV) = (AP – SP) × AQ
Materials usage variance (MUV) = (AQ – SQ) × SP
Total material cost variance (MCV) = (AP × AQ) – (SP × SQ)
- Or MCV = MPV + MUV.

Example:

Standard: 2 kg of material per unit at R6 per kg → Standard DM cost = R12 per unit.
Actual production: 4,000 units.
Actual total material used: 8,500 kg at total cost R52,700.

Compute:

SP = R6 per kg.
AP = Total cost / AQ = R52,700 / 8,500 = R6.20 per kg.
SQ = 2 kg × 4,000 units = 8,000 kg.
AQ = 8,500 kg.

MPV = (AP – SP) × AQ
= (R6.20 – R6.00) × 8,500
= R0.20 × 8,500
= R1,700 U (unfavourable, because AP > SP).

MUV = (AQ – SQ) × SP
= (8,500 – 8,000) × R6.00
= 500 × R6.00
= R3,000 U (used more than standard).

MCV = MPV + MUV = R1,700 U + R3,000 U = R4,700 U.

Interpretation: Higher price and higher usage both contributed to overspending. EMAC3714 may ask possible reasons: poor purchasing negotiations, higher‑grade material, wastage due to machine issues, etc.

4.5.2 Direct Labour Variances

Let:

SR = Standard labour rate per hour.
AR = Actual labour rate per hour.
SH = Standard hours allowed for actual output.
AH = Actual hours worked.

Formulas:

Labour rate variance (LRV) = (AR – SR) × AH
Labour efficiency variance (LEV) = (AH – SH) × SR
Total labour cost variance (LCV) = (AR × AH) – (SR × SH)
- Or LCV = LRV + LEV.

Example:

Standard: 1.5 hours per unit at R40 per hour → Standard DL cost = R60 per unit.
Actual production: 3,000 units.
Actual hours: 4,600 hours.
Actual total labour cost: R190,600.

Compute:

SR = R40/hour.
AR = R190,600 / 4,600 = R41.43/hour.
SH = 1.5 × 3,000 = 4,500 hours.
AH = 4,600 hours.

LRV = (AR – SR) × AH
= (R41.43 – R40.00) × 4,600
= R1.43 × 4,600 ≈ R6,578 U.

LEV = (AH – SH) × SR
= (4,600 – 4,500) × R40
= 100 × R40 = R4,000 U.

LCV = R6,578 U + R4,000 U = R10,578 U.

Interpretation: Unfavourable rate variance suggests higher wages (e.g. overtime, higher‑skilled workers); unfavourable efficiency variance suggests inefficiencies (e.g. poor training, machine breakdowns).

EMAC3714 may ask you to calculate variances and discuss at least two possible causes and suggest managerial actions.

5. Short‑Term Decision‑Making and Performance Measurement

The final core area for EMAC3714 is short‑term decision‑making based on relevant costing, and the measurement of performance using responsibility accounting concepts and financial/ non‑financial indicators.

5.1 Relevant Costing for Special Orders

A special order is a one‑time order, usually at a price different from the normal selling price, often for export or a special market. The key principle: consider incremental (differential) revenues and costs and available capacity.

Example: UFS Steelworks

UFS Steelworks produces standard steel brackets:

Normal selling price: R300 per unit.
Variable manufacturing cost: R180 per unit.
Fixed manufacturing cost: R300,000 per month (currently fully absorbed based on normal volume).
Capacity: 5,000 units per month.
Current normal sales: 4,000 units per month.
A foreign buyer offers to purchase 800 units at R230 per unit. No additional fixed costs; normal sales will not be affected. Shipping costs of R10 per unit apply only to this special order.

Relevant analysis:

Incremental revenue = R230 × 800 = R184,000.
Incremental variable manufacturing cost = R180 × 800 = R144,000.
Incremental shipping cost = R10 × 800 = R8,000.
Total incremental cost = R144,000 + R8,000 = R152,000.
Incremental profit = R184,000 – R152,000 = R32,000.

As long as there is spare capacity and no impact on regular sales, the special order should be accepted because it adds R32,000 to profit.

If capacity were constrained (e.g. already selling 5,000 units at R300 each), then accepting the special order would displace normal sales. The opportunity cost of lost contribution from regular sales must be included, and the decision may change.

Key EMAC3714 exam steps:

Identify whether spare capacity exists.
List all incremental revenues and costs (ignore sunk and unavoidable fixed costs).
Consider qualitative factors (customer relationships, price precedent, quality requirements).

5.2 Make‑or‑Buy (Outsourcing) Decisions

Earlier, Section 2.5 introduced the concept; here, it is extended in a more exam‑style format.

Example: UFS Components – revisited with capacity

UFS Components uses a part in its machines. Data per unit:

Direct materials: R50
Direct labour: R40
Variable overhead: R20
Fixed overhead (allocated): R30
Total manufacturing cost: R140 per unit

Annual requirement: 15,000 units.
An outside supplier offers to supply the part for R120 per unit. If the part is bought, R200,000 of fixed overhead (currently included in the R30 allocated) will be avoided; the remaining fixed overhead, R250,000, will continue regardless of the decision. The space released if production is stopped can be used to produce another product generating additional contribution of R150,000 per year.

Current in‑house production fixed overhead:

Total fixed OH allocated to parts = R30 × 15,000 = R450,000.
Of this, R200,000 is avoidable; R250,000 unavoidable.

Relevant cost of making all 15,000 units:

Direct materials = 15,000 × R50 = R750,000
Direct labour = 15,000 × R40 = R600,000
Variable overhead = 15,000 × R20 = R300,000
Avoidable fixed OH = R200,000
Total relevant cost = R750,000 + R600,000 + R300,000 + R200,000 = R1,850,000

Per unit relevant cost to make = R1,850,000 / 15,000 = R123.33

Relevant cost of buying:

Purchase cost = 15,000 × R120 = R1,800,000
Opportunity cost of using space for another product = (– R150,000), meaning buy option gains this benefit. In relevant cost terms for buying, we add opportunity cost as if it were a cost of making:
- For make option: opportunity cost = R150,000 (lost).
- For buy option: opportunity cost = 0.

It is clearer to compute net benefit:

Option 1 – Make:

Cash outflows (relevant): R1,850,000
Opportunity cost (lost benefit): R150,000
Total economic cost = R2,000,000

Option 2 – Buy:

Cash outflows: R1,800,000
Opportunity to earn additional contribution: +R150,000

Net economic cost of buying, considering benefit, is R1,800,000 – R150,000 = R1,650,000 effective economic burden, or you can say total cash cost R1,800,000 but net economic benefit R150,000.

Comparison:

Make: “cost” R2,000,000
Buy: “cost” R1,650,000

Therefore, buying is preferable when including the R150,000 additional contribution.

EMAC3714 will likely present information in paragraphs; mark up avoidable vs unavoidable costs, identify opportunity costs and then present your computations in a structured format.

5.3 Product Mix Decisions with Limiting Factors

A frequent exam topic is choosing the optimal product mix when there is a limiting factor, such as machine hours or labour hours.

Key approach:

Identify the limiting factor (e.g. machine hours).
Compute contribution per unit of the limiting factor.
Rank products based on contribution per limiting factor.
Allocate the limiting resource starting from highest ranking to meet demand and capacity constraints.

Example: UFS Electronics

UFS Electronics makes products P and Q. Data per unit:

	P	Q
Selling price (R)	500	450
Variable cost (R)	300	270
Contribution (R)	200	180
Machine hours	4	3

Available machine hours: 8,000 per month.
Maximum demand: P: 1,400 units; Q: 2,000 units.

Contribution per machine hour:

P: R200 / 4 = R50 per hour
Q: R180 / 3 = R60 per hour

Rank: Q first, then P.

Allocate machine hours:

Satisfy all of Q’s demand first, up to 2,000 units:
- Hours required = 2,000 × 3 = 6,000 hours.
- Remaining hours = 8,000 – 6,000 = 2,000 hours.
Use remaining hours for P:
- Units of P = 2,000 hours / 4 = 500 units.

Contribution:

P: 500 units × R200 = R100,000
Q: 2,000 units × R180 = R360,000
Total contribution = R460,000

If fixed costs are R300,000, profit = R460,000 – R300,000 = R160,000.

EMAC3714 may also extend this to multiple limiting factors or require linear programming approaches (depending on syllabus depth), but the core principle remains: maximize contribution per unit of the scarce resource.

5.4 Dropping a Product/Department

Decisions to discontinue a product or department revolve around whether the segment contributes to covering fixed costs and profit.

Key rule: A segment should be dropped only if its avoidable fixed costs exceed its contribution margin, and qualitative factors also favour discontinuation.

Example: UFS Retail – Department Shutdown

UFS Retail operates three departments: A, B, and C. Summary (per month):

Department	Sales (R)	Variable Costs (R)	Contribution (R)	Direct Fixed Costs (R)	Allocated Common Fixed Costs (R)
A	300,000	210,000	90,000	40,000	30,000
B	250,000	170,000	80,000	35,000	25,000
C	150,000	130,000	20,000	15,000	15,000
Total	700,000	510,000	190,000	90,000	70,000

Common fixed costs of R70,000 continue regardless of whether any department is closed and are allocated based on some arbitrary basis (e.g. floor area).

Total profit currently:

Total contribution (R190,000) – Direct fixed (R90,000) – Common fixed (R70,000) = R30,000.

Consider dropping Department C. If C closes:

Lost contribution = R20,000.
Direct fixed costs saved (avoidable) = R15,000.
Common fixed costs remain at R70,000 but would be reallocated to A and B.

Effect on profit:

Net decrease in profit = Lost contribution – Fixed costs saved = R20,000 – R15,000 = R5,000.
New profit = R30,000 – R5,000 = R25,000.

Since profit decreases if C is dropped, from purely financial perspective C should not be closed, despite its small contribution. EMAC3714 exam questions may ask for:

A statement comparing current profit vs profit if discontinued.
A recommendation with justification.
Discussion of qualitative considerations (e.g. customer traffic, strategic reasons).

5.5 Performance Measurement and Responsibility Accounting

Performance measurement links management accounting data to managerial accountability.

Responsibility accounting divides an organization into segments, each with a manager responsible for certain revenues, costs, or investments.

Types of responsibility centres:

Cost centres – Manager controls costs only (e.g. production departments).
Revenue centres – Manager responsible for revenue generation (e.g. sales territories).
Profit centres – Manager accountable for both revenues and costs (e.g. a store branch).
Investment centres – Manager responsible for profit and the assets used to generate that profit (e.g. a division with significant capital employed).

5.5.1 Financial Performance Measures

Common measures covered in EMAC3714, particularly for investment centres:

Return on Investment (ROI)

ROI = (Segment profit / Segment assets) × 100%

Example:

UFS Manufacturing Division has segment profit of R800,000 and assets of R4,000,000.

ROI = (R800,000 / R4,000,000) × 100% = 20%.

Issues:

ROI can lead to short‑termism: managers may reject projects that reduce their division’s ROI even if they benefit the company as a whole.

Residual Income (RI)

RI = Segment profit – (Required rate of return × Segment assets)

If required rate is 12%:

Capital charge = 0.12 × R4,000,000 = R480,000
RI = R800,000 – R480,000 = R320,000

RI encourages acceptance of projects that earn more than the required rate of return, aligning divisional behaviour with overall company goals.

Profit Margin and Asset Turnover

ROI can also be broken down:

ROI = Profit margin × Asset turnover
Profit margin = Profit / Sales
Asset turnover = Sales / Assets

This DuPont analysis helps identify whether ROI problems stem from low margins or low asset utilization.

Example:

If the division had sales of R8,000,000:

Profit margin = R800,000 / R8,000,000 = 10%
Asset turnover = R8,000,000 / R4,000,000 = 2
ROI = 10% × 2 = 20%.

In EMAC3714, questions may require computation of ROI and RI for competing investment opportunities and ask which performance measure leads to better goal congruence.

5.5.2 Non‑Financial Performance Measures and the Balanced Scorecard

Exclusive reliance on financial measures is increasingly seen as narrow. The Balanced Scorecard (though more prominent in strategy modules like those similar to Unisa MNG3702, it is relevant in EMAC3714 too) incorporates multiple perspectives:

Financial perspective – profitability, ROI, RI, sales growth.
Customer perspective – customer satisfaction scores, market share, delivery times.
Internal business processes – defect rates, cycle times, efficiency measures.
Learning and growth – employee training hours, staff turnover, innovation rates.

For a UFS‑based manufacturing firm, examples:

Financial: Operating profit margin of 12%, cash conversion cycle.
Customer: On‑time delivery ratio of 95%, complaint rate.
Internal: Percentage of products passing quality inspection first time.
Learning: Average number of training hours per employee per year.

EMAC3714 theory questions may ask:

Why non‑financial measures are important.
How a Balanced Scorecard improves performance measurement.
To propose at least two measures in each perspective for a given case company.

5.5.3 Behavioural and Ethical Issues in Performance Measurement

Performance measures influence behaviour; poorly designed systems can lead to dysfunctional behaviour, such as:

Managers cutting necessary maintenance to meet short‑term profit targets.
Excessive focus on easily measured indicators, neglecting long‑term objectives.
Budgetary slack (deliberately underestimating revenues or overestimating costs).

Exams may require a discussion of budgetary participation:

Top‑down budgets – imposed by senior management; may lack realism, lead to low motivation.
Bottom‑up (participative) budgets – prepared with input from lower‑level managers; more realistic but open to slack.

Ethical tensions arise when:

Performance evaluation pressures managers to falsify figures (e.g. misclassifying expenses as assets).
Cost cutting leads to compromising product quality or safety.

EMAC3714 answers should link back to earlier ethical principles (integrity, objectivity, etc.), suggesting:

Transparent communication of performance criteria.
Balanced measures that discourage manipulation.
Strong internal controls and ethical leadership.

This study guide synthesizes the key management accounting concepts central to EMAC3714: Management Accounting Key Concepts in the University of the Free State (UFS) BAcc curriculum. Mastery of cost classification, CVP analysis, budgeting, standard costing, relevant costing, and performance measurement – together with a clear understanding of ethical and behavioural implications – provides a robust foundation for tackling EMAC3714 exam questions and related management accounting modules across South African universities.
