Break-even CalculatorACCOUNTING · COST ACCOUNTING

The break-even point is the number of units you must sell to cover all your costs. Below it — you lose. Above it — you profit. This is exactly what your Gr 12 Manufacturing & Cost Accounting questions ask.

Contribution / unit R60
Break-even units 200
Break-even value R30 000
Profit at 400 units R12 000

How it works

1
Contribution per unit = SP − AVCHow much each unit "contributes" toward fixed costs after paying its own variable cost.
2
Break-even units = TFC ÷ Contribution per unitFixed costs ÷ how much each unit contributes.
3
Break-even value = Break-even units × SPWhat those units are worth in rands.
CAPS exam tip: If the question says "How many units must be sold to make a profit of R8 000?", use: Units = (TFC + Target profit) ÷ Contribution per unit. Try it: (12 000 + 8 000) ÷ 60 = 334 units (rounded up).

Financial Ratio AnalyserACCOUNTING · ANALYSIS & INTERPRETATION

Enter a company's figures and instantly get the ratios that carry the most marks in the exam. Then read the interpretation — because that's where learners lose marks.

Depreciation SimulatorACCOUNTING · FIXED ASSETS

The two methods side-by-side. This is the exact calculation your Gr 12 paper asks — and where learners confuse "cost price" with "carrying value".

YearCost price methodDiminishing balance method
Key idea: The cost price method (straight-line) always depreciates the same amount every year. The diminishing balance method depreciates a fixed % of the carrying value — so it starts high and gets smaller each year. This is why the two methods give different answers, and why the exam asks which is better for which kind of asset.

VAT & Invoice BuilderACCOUNTING · VAT

Every invoice in the exam needs VAT calculated correctly. Inclusive vs exclusive. Input vs output. Let's build one.

The two formulas

To ADD VAT

VAT = Exclusive × rate ÷ 100

Inclusive = Exclusive + VAT

Or: Inclusive = Exclusive × (1 + rate/100)

To EXTRACT VAT

Exclusive = Inclusive × 100 ÷ (100 + rate)

VAT = Inclusive − Exclusive

Or: VAT = Inclusive × rate ÷ (100 + rate)

Cash Flow BuilderACCOUNTING · CASH FLOW STATEMENT

The Cash Flow Statement is a 30-mark question that most learners avoid. Here's how the three sections fit together — with the cash reconciliation at the end.

Market Structure ComparatorECONOMICS · DYNAMICS OF MARKETS

Compare the four market structures side by side. This is the comparison you're asked to table in the exam — memorise the differences.

Perfect Competition

Number of firms: Many

Product: Homogeneous

Price control: Price taker

Entry: Completely free

Info: Perfect

Long-run profit: Normal only

Examples: Maize, wheat, forex markets

Monopolistic Competition

Number of firms: Many, fewer than perfect

Product: Differentiated

Price control: Some — price maker

Entry: Free

Info: Imperfect

Long-run profit: Normal only

Examples: Restaurants, hair salons, clothing

Oligopoly

Number of firms: Few large firms

Product: Homogeneous or differentiated

Price control: Interdependent price maker

Entry: Restricted (high barriers)

Info: Imperfect

Long-run profit: Can be economic

Examples: Banks, cell networks, airlines

Monopoly

Number of firms: One

Product: Unique (no substitutes)

Price control: Price maker

Entry: Completely blocked

Info: Controlled by monopolist

Long-run profit: Economic — indefinitely

Examples: Eskom, De Beers (historically)

Exam tip: The exam often asks you to table these differences across criteria like: number of sellers, nature of product, collusion, restrictions on entry, market power, profit in the long run. Use the columns above as your template.

Inflation EngineECONOMICS · INFLATION

See what inflation actually does to money. Type in the numbers and watch purchasing power collapse — or wages lag behind prices.

Price after period—
Your money is worth—
Total increase—

Who wins and who loses?

Winners

• Debtors (borrowers) — repay loans with cheaper money

• Owners of physical assets (houses, land, gold)

• Businesses that can raise prices faster than costs

• The Government — bracket creep in taxes

Losers

• Pensioners on fixed incomes

• Creditors (lenders) — repaid with devalued money

• Savers in bank accounts

• Low-income households — food & transport dominate their budget

Watch out: The SARB's target range is 3%–6%. Below 3% risks deflation. Above 6% requires tightening monetary policy (raising repo rate).

Multiplier MachineECONOMICS · CIRCULAR FLOW

A small injection causes a much larger change in income. Watch it happen — then match your answer to the two-, three-, and four-sector formulas.

0.80
Multiplier (2-sector)5.00
Total change in incomeR50 m
Marginal propensity to save0.20

Round-by-round spending

Three-sector formula: K = 1 ÷ (mps + mrt) — includes taxation as a leakage.
Four-sector formula: K = 1 ÷ (mps + mrt + mpm) — includes imports as a leakage.
Every leakage makes the multiplier smaller. That's why open economies have smaller multipliers than closed ones.

Enter the numbers from any BoP table and see whether the country is in surplus or deficit — and what it means for the rand.

Business Forms ComparatorBUSINESS STUDIES · FORMS OF OWNERSHIP

Six forms of ownership compared across the criteria the exam asks about. Click a criterion to highlight.

Criterion Sole Trader Partnership Close Corp Private Co (Pty) Public Co (Ltd) State-Owned
Exam tip: The question usually gives a scenario (e.g. "Thabo has R15 000 and wants to start a small business with one partner"). You need to recommend a form and motivate with 3+ reasons tied to the criteria above.

Legislation MatcherBUSINESS STUDIES · MACRO LEGISLATION

Every Grade 12 Business Studies paper tests whether you can match a real-world scenario to the correct Act. Let's drill it.

The 7 key Acts

Skills Development Act (1998)

Sets up SETAs, learnerships, and the 1% skills levy. Promotes employee training.

Labour Relations Act (1995)

Covers trade unions, strikes, CCMA, workplace forums, unfair dismissal.

Employment Equity Act (1998)

Prevents discrimination; mandates affirmative action for designated groups.

Basic Conditions of Employment Act (1997)

Working hours, leave, overtime, termination rules.

BBBEE Act (2003)

Redresses apartheid inequities via ownership, management, skills, procurement points.

National Credit Act (2005)

Consumer credit protection, affordability assessment, cooling-off period.

Consumer Protection Act (2008)

Consumer rights — fair marketing, plain language, right to return goods.

Business Strategy ExplorerBUSINESS STUDIES · BUSINESS STRATEGIES

Four families of strategies. Click any to see what it means and when a business would use it.

1. Integration

Combining with other businesses to shorten the distribution channel.

Forward: buy a distributor or retailer

Backward: buy your supplier

Horizontal: merge with a direct competitor

2. Intensive

Squeezing more out of what you already have.

Market penetration: sell more of same product to same market

Market development: same product, new market

Product development: new product, same market

3. Diversification

New products, new markets.

Concentric: related tech/customers

Horizontal: unrelated, same customers

Conglomerate: entirely unrelated

4. Defensive

Used when under pressure.

Retrenchment: cut costs, reduce staff

Divestiture: sell off a division

Liquidation: close the business entirely

Exam tip: If a case study mentions "the business bought its main supplier", that's backward integration. If it "opened outlets in another country", that's market development. If it "closed three branches to survive the recession", that's retrenchment. Learn the trigger phrases.
