Cambridge A Level Business (9609) rewards calculations supported by sharp analysis and judgement. This reference sheet brings together the quantitative formulas (ratios, break-even, NPV, elasticity) and the strategic frameworks (Ansoff, Porter, BCG, SWOT, PESTLE) examiners expect in case-study and data-response answers.
Profitability, liquidity, gearing, and efficiency ratios
Break-even, contribution, and investment appraisal techniques
HR and marketing metrics with worked formulas
Ansoff, Porter, BCG, SWOT, and PESTLE frameworks
Always quote the formula, calculate, and then INTERPRET — examiners reward analysis, not just arithmetic.
Gross profit margin
(Gross Profit ÷ Revenue) × 100 Operating (net) profit margin
(Operating Profit ÷ Revenue) × 100 Profit for the year margin
(Profit for the Year ÷ Revenue) × 100 Return on Capital Employed (ROCE)
(Operating Profit ÷ Capital Employed) × 100, where Capital Employed = Non-current Liabilities + Total Equity ROCE is the headline measure of how efficiently a business uses its long-term funding.
Current ratio
Current Assets ÷ Current Liabilities (healthy ≈ 1.5–2:1) Acid test (quick) ratio
(Current Assets − Inventories) ÷ Current Liabilities (healthy ≈ 1:1) Below 1 may indicate cash-flow risk; very high values may indicate idle assets.
Gearing
(Non-current Liabilities ÷ Capital Employed) × 100 (high gearing > 50% = greater financial risk) Asset turnover
Revenue ÷ Capital Employed (how productively assets generate sales) Inventory turnover
Cost of Sales ÷ Average Inventory (times per period) Trade receivables days
(Trade Receivables ÷ Revenue) × 365 Trade payables days
(Trade Payables ÷ Cost of Sales) × 365 Decision-making questions almost always test these calculations.
Contribution per unit
Selling Price per Unit − Variable Cost per Unit Total contribution
Contribution per Unit × Units Sold Profit
Total Contribution − Fixed Costs Break-even output (units)
Fixed Costs ÷ Contribution per Unit Break-even revenue
Break-even units × Selling Price Margin of safety
Current (or Budgeted) Output − Break-even Output Target profit output
(Fixed Costs + Target Profit) ÷ Contribution per Unit Evaluate capital projects using payback, ARR, and NPV — show working, then judge.
Time taken to recover initial investment from net cash inflows Within a year
Payback = full years + (Outstanding amount ÷ Cash flow in next year) × 12 months Strength: simple, focuses on liquidity. Weakness: ignores cash flows after payback and the time value of money.
ARR = (Average Annual Profit ÷ Initial Investment) × 100 Average annual profit
(Total Net Cash Inflows − Initial Investment) ÷ Project Life (years) NPV = Σ (Net Cash Flow × Discount Factor) − Initial Investment Discount factor
1 ÷ (1 + r)^n where r = discount rate and n = year Positive NPV → accept the project. Higher NPV is preferred when comparing alternatives.
Workforce planning questions test these standard formulas.
Labour turnover
(Number of Staff Leaving in Period ÷ Average Number Employed) × 100 Labour stability index
(Number of Staff with > 1 Year's Service ÷ Total Staff) × 100 Labour productivity
Total Output per Period ÷ Number of Employees Absenteeism rate
(Number of Staff Absent ÷ Total Staff) × 100, or (Days Lost ÷ Days Available) × 100 Recruitment cost per hire
Total Recruitment Costs ÷ Number of Employees Hired Quantify market position and demand sensitivity.
Market share
(Firm's Sales ÷ Total Market Sales) × 100 Market growth
((New Market Size − Old Market Size) ÷ Old Market Size) × 100 Moving average
Mean of the last n periods (e.g. 3-period or 4-period); used to smooth out short-term fluctuations Time series
Series = Trend + Seasonal Variation + Random/Cyclical Variation Extrapolation assumes past trends continue — risky in volatile markets.
Price elasticity (PED)
% Change in Quantity Demanded ÷ % Change in Price (sign typically negative) Income elasticity (YED)
% Change in Quantity Demanded ÷ % Change in Income Interpretation
|PED| > 1 = elastic (price sensitive); |PED| < 1 = inelastic; YED > 0 = normal good; YED < 0 = inferior good Operations metrics often appear in Paper 2 numerical questions.
(Current Output ÷ Maximum Possible Output) × 100 Higher utilisation spreads fixed costs but reduces flexibility and increases pressure on staff/equipment.
Labour productivity
Output per Period ÷ Number of Employees Capital productivity
Output per Period ÷ Capital Employed Unit cost
Total Cost ÷ Total Output Reorder level
Lead Time × Average Daily Usage Buffer stock
Minimum stock held to cover unexpected demand or supply delays Examiners reward correct, applied use of frameworks — not memorised definitions.
Growth strategy options based on product / market combinations.
Existing Product / Existing Market = Market Penetration (lowest risk) New Product / Existing Market = Product Development Existing Product / New Market = Market Development New Product / New Market = Diversification (highest risk) Industry attractiveness analysis.
1) Threat of new entrants 2) Bargaining power of buyers 3) Bargaining power of suppliers 4) Threat of substitutes 5) Competitive rivalry within the industry Portfolio analysis using market share vs market growth.
Star — high share, high growth (invest) Cash Cow — high share, low growth (harvest) Question Mark / Problem Child — low share, high growth (build or divest) Dog — low share, low growth (divest) SWOT (internal & external)
Strengths, Weaknesses (internal) | Opportunities, Threats (external) PESTLE (macro environment)
Political, Economic, Social, Technological, Legal, Environmental Cambridge marks reward judgement, application, and balanced argument.
Define key terms precisely. Use the case context — never just generic theory. For 'Analyse' questions, develop chains of reasoning: cause → effect → business consequence. Show ALL calculation working — partial credit is awarded for method even if the final figure is wrong. Always interpret a calculated figure in the context of the business; quote earlier figures or trends for comparison. Plan a clear judgement before writing — state, justify, qualify with key factors (e.g. market position, finance, risk). Use the CIE evaluation phrase pattern: 'It depends on...' followed by a specific contextual factor and why it matters. Top-band answers reach a supported judgement, not a balanced restatement.
Boost your Cambridge exam confidence with these proven study strategies from our tutoring experts.
Re-do every ratio, break-even, and NPV question from past papers until you can complete the working in under 4 minutes. Examiners give partial credit only when working is clearly shown.
Pick a business in the news each week and apply Ansoff, Porter, or PESTLE. This builds the contextual application examiners credit highly.
For every analytical question, state your overall judgement and qualify it with at least one 'it depends on...' factor drawn from the case context.
Don't analyse a ratio in isolation — compare year on year, against competitors, and against industry norms. Trends are what examiners reward.
