Efficiency and gearing ratio analysis (HL) — how well a firm uses its working capital and how much it relies on debt
This is an HL-only subtopic (examined in Paper 2 and Paper 3). It goes beyond the SL profitability and liquidity ratios of 3.5 to ask two further questions. First, the GEARING ratio: how much of a firm's capital employed is financed by long-term debt rather than shareholders' equity — a measure of financial risk. Second, the EFFICIENCY ratios: inventory (stock) turnover, debtor (trade receivable) days and creditor (trade payable) days — measures of how well the firm manages its working capital cycle. The examinable skill is not just to calculate but to interpret each figure IN CONTEXT and, at AO3, to evaluate whether a firm's gearing and efficiency are APPROPRIATE given its industry, growth stage and risk appetite. High gearing is not automatically 'bad', and a fast inventory turnover is not automatically 'good' — it always depends on the situation.
At a glance
HL-ONLY subtopic — assessed in Paper 2 and Paper 3. Builds on the SL ratios in 3.5 (profitability and liquidity).
High gearing → higher financial risk (interest must be paid whether or not profits are made) but debt is cheaper than equity and keeps control with existing owners.
EFFICIENCY ratios measure how well working capital is managed: how fast stock sells, how quickly customers pay, how long the firm takes to pay suppliers.
DAYS ratios always multiply by 365. Lower debtor days = good (cash in faster); higher creditor days can be good (free short-term finance) but risks supplier relationships.

The gearing ratio: how much the firm relies on debt
▼
Gearing measures what proportion of a firm's long-term capital comes from debt rather than equity. It is a measure of financial RISK, not of profitability.
A business raises long-term capital from two sources: equity (share capital plus retained earnings — money belonging to the owners) and long-term debt (non-current liabilities such as bank loans, mortgages and debentures). Together these make up capital employed. The gearing ratio tells us how much of that capital employed is financed by debt.
The formula is:
Gearing (%) = Non-current liabilities ÷ Capital employed × 100, where Capital employed = equity + non-current liabilities.
A firm is described as:
Highly geared when gearing is above 50% — more than half of long-term capital is borrowed.
Low geared when gearing is below 25% — the firm relies mainly on the owners' money.
Neutrally geared in between.
Gearing matters because interest on debt is a fixed obligation: it must be paid whether the firm makes a profit or a loss. Equity, by contrast, only rewards shareholders (through dividends) when the firm chooses to and can afford to. So the more highly geared a firm is, the greater its financial risk — but the more it can also amplify returns to owners in good years.
Capital employed = equity + non-current liabilities (the denominator).
Highly geared > 50%; low geared < 25%.
Gearing measures financial RISK, not profitability — do not confuse it with ROCE.
Interest is a fixed cost owed to lenders; dividends are discretionary rewards to owners.
Implications of high vs low gearing (and interest rates)
▼
High gearing brings cheaper capital and preserves owner control, but raises risk and vulnerability to interest-rate rises. The 'right' level depends on the firm.
Whether high or low gearing is desirable depends on the firm's circumstances. The table below sets out the trade-offs.
HIGH gearing (>50%)
LOW gearing (<25%)
Financial risk
High — interest must be paid even in a downturn
Low — few fixed interest obligations
Cost of capital
Debt is usually cheaper than equity (interest is tax-deductible)
Relies on more expensive equity
Control
Existing owners keep control (no new shares issued)
Issuing shares can dilute owners' control
Raising more finance
Hard — lenders wary, may refuse further loans
Easy — spare borrowing capacity
Vulnerability to interest rates
High — a rate rise increases interest costs sharply
Low — little debt to service
The effect of interest rates is crucial. When central-bank interest rates RISE, a highly geared firm faces a much larger interest bill, squeezing profit and cash flow — and may struggle to meet repayments. When rates FALL, high gearing becomes cheaper and the firm benefits. A firm considering taking on more debt must therefore forecast where interest rates are heading.
Gearing also interacts with the stage of the business cycle and the industry. Firms with stable, predictable cash flows (e.g. utilities, supermarkets) can safely carry higher gearing because they can reliably service the interest. Firms in volatile, cyclical industries (e.g. construction, tourism) are safer with low gearing.
Advantages of debt: cheaper than equity, tax-deductible interest, keeps control with owners, no dilution.
Drawbacks of high gearing: fixed interest burden, higher insolvency risk, harder to borrow more, exposed to rate rises.
Stable-cash-flow industries can carry higher gearing safely than cyclical ones.
Efficiency ratios: managing the working capital cycle
▼
Efficiency (activity) ratios show how well a firm turns stock into cash and manages the timing of payments in and out — the heartbeat of working capital.
Efficiency ratios examine how well the firm manages its working capital — the short-term assets and liabilities that fund day-to-day trading. There are three key measures.
1. Inventory (stock) turnover — how many times a year the firm sells and replaces its stock.
As a number of times: Cost of goods sold ÷ average inventory (a higher number = faster-selling stock).
As a number of days: Average inventory ÷ cost of goods sold × 365 (a lower number of days = faster-selling stock).
A HIGH turnover (low days) suits perishable or fast-moving goods (a bakery, a supermarket). A LOW turnover (high days) is expected for high-value, slow-selling goods (a jeweller, a luxury-car dealer). Turnover that is too high can signal stock-outs and lost sales; too low ties up cash in unsold stock.
2. Debtor days (trade receivable days) — the average number of days customers take to pay.
Trade receivables ÷ revenue × 365.
LOWER is generally better — cash comes in faster, improving liquidity. Rising debtor days may mean weak credit control or customers in difficulty.
3. Creditor days (trade payable days) — the average number of days the firm takes to pay its suppliers.
Trade payables ÷ cost of goods sold × 365.
HIGHER creditor days act as free short-term finance (the firm holds onto cash longer). But paying too slowly can damage supplier relationships, forfeit early-payment discounts and cause suppliers to withdraw credit.
Together these three feed the cash conversion / working-capital cycle: inventory days + debtor days − creditor days = the number of days cash is tied up in operations. Managing all three well keeps the firm liquid without over-borrowing.
Inventory turnover: how fast stock sells (times/year or days).
Debtor days: how fast customers pay — lower is better for cash flow.
Creditor days: how long the firm takes to pay suppliers — higher gives free finance but risks relationships.
All three ratios interpreted against the INDUSTRY norm, never in isolation.
Strategies to improve gearing and efficiency
▼
Gearing can be reduced by raising equity or converting debt; efficiency is improved by tighter credit control, better stock management and negotiating supplier terms.
If analysis shows gearing is too high or efficiency is poor, managers have several levers — each with drawbacks.
Reducing (or adjusting) gearing:
Rights issue / share issue — raise new equity to repay debt, cutting gearing. But it dilutes existing owners and equity is more expensive.
Debt-for-equity swap — lenders exchange loans for shares, removing debt from the balance sheet. Reduces risk but again dilutes control.
Retain more profit — use retained earnings instead of new borrowing. Slow, and reduces dividends.
Sell and lease back assets to repay loans.
Improving efficiency:
Tighter credit control to cut debtor days: credit checks, shorter payment terms, chasing late payers, early-settlement discounts, or factoring receivables.
Negotiating longer creditor terms to extend creditor days as free finance — without souring supplier relationships.
The key evaluation point is that these strategies trade off against each other and against other objectives. Extending creditor days improves the working-capital cycle but can anger suppliers; JIT cuts stock-holding costs but risks stock-outs; a rights issue cuts gearing but dilutes owners. There is rarely a costless fix.
Lower gearing: rights issue, debt-for-equity swap, retain profit, sale-and-leaseback.
Faster inventory turnover: JIT, demand forecasting, clearing dead stock.
Higher creditor days: renegotiate supplier terms — but protect relationships.
Evaluating whether gearing and efficiency are appropriate
▼
The AO3 skill: judge a firm's ratios against its industry, growth stage and risk appetite — there is no universally 'right' number.
The highest-mark questions ask you to EVALUATE whether a firm's gearing and efficiency are appropriate — a judgement, not a calculation. Three lenses structure a strong answer.
Industry. Capital-intensive industries (utilities, airlines, telecoms) typically operate at higher gearing because their assets support borrowing and their cash flows are stable. A software start-up carrying the same gearing would be alarming. Likewise, a supermarket's inventory turnover of 20+ times a year is healthy, while a furniture retailer turning stock 4 times a year may be perfectly normal.
Growth stage. A young, fast-growing firm may deliberately take on high gearing to fund expansion — accepting risk for growth. A mature firm generating strong cash may prefer low gearing to protect stability. Rising debtor days in a growth phase might reflect deliberately generous credit terms to win customers, not weak control.
Risk appetite and context. Owners and managers differ in how much financial risk they will accept, and this interacts with the economic climate. In a low-interest, growing economy, higher gearing may be sensible; approaching a recession or rate rises, the same gearing looks reckless.
The diagram below contrasts a low-geared and a highly geared capital structure. Neither is 'correct' in the abstract — the judgement always depends on the firm's situation.
A top-band answer weighs both sides, uses the firm's own data, and reaches a justified conclusion — for example: 'Given that TechCo operates in a volatile industry and interest rates are rising, its 68% gearing is inappropriately high and a rights issue is advisable, even at the cost of some dilution.'
Judge ratios against the INDUSTRY norm, not an absolute benchmark.
Consider the firm's GROWTH STAGE — expansion may justify higher gearing.
Factor in RISK APPETITE and the interest-rate / economic climate.
A strong AO3 answer reaches a justified, context-specific conclusion.
High gearing = higher financial risk and vulnerability to interest-rate rises, but cheaper capital and preserved control.
Inventory turnover, debtor days and creditor days measure how efficiently working capital is managed.
DAYS ratios multiply by 365; lower debtor days is good, higher creditor days gives free finance but risks suppliers.
Improve gearing via rights issue or debt-for-equity swap; improve efficiency via credit control and JIT.
Evaluate appropriateness against industry, growth stage and risk appetite — no universally 'right' figure.

Step-by-step solutions to past-paper-style questions on efficiency ratio analysis, written exactly the way a tutor would explain them at the board.
1Defining the gearing ratio
Getting started• gearing, AO1, definition
▼
Question
Define the term gearing ratio. [2]
Step-by-step solution
Step 1
State what gearing measures — the proportion of a firm's capital employed that is financed by long-term (non-current) debt rather than equity.
Step 2
Add the idea that it is a measure of financial risk. Two clear points earn both AO1 marks.
Answer
The gearing ratio is a measure of the proportion of a business's capital employed that is financed by long-term debt (non-current liabilities) rather than by equity. It indicates the firm's financial risk — the higher the gearing, the more the firm depends on borrowed money and the greater its fixed interest obligations.
Examiner tip
AO1: one mark for identifying it as debt as a proportion of capital employed, one mark for the risk/long-term-debt dimension. No calculation needed here.
2Calculating the gearing ratio
Getting started• gearing, AO2, calculation
▼
Question
A firm has non-current liabilities of 400,000,sharecapitalandreserves(equity)of600,000. Calculate its gearing ratio. [2]
Step-by-step solution
Step 1
Find capital employed = equity + non-current liabilities.
Capitalemployed=600,000+400,000=1,000,000
Step 2
Apply the gearing formula: non-current liabilities ÷ capital employed × 100.
Gearing=400,000/1,000,000x100=40
Answer
Gearing = 400,000 ÷ 1,000,000 × 100 = 40%. The firm is neutrally geared (between 25% and 50%).
Examiner tip
AO2: one mark for the correct method (using capital employed as the denominator), one for the accurate 40% with a % sign. Do not use total liabilities.
A business has trade receivables of 30,000andannualrevenueof365,000. Calculate its debtor (trade receivable) days. [2]
Step-by-step solution
Step 1
Use the debtor days formula: trade receivables ÷ revenue × 365. Remember to multiply by 365 for a 'days' figure.
Debtordays=30,000/365,000x365
Step 2
Compute the value.
=0.0822x365=30days
Answer
Debtor days = 30,000 ÷ 365,000 × 365 = 30 days. On average customers take 30 days to pay.
Examiner tip
AO2: one mark for the method (including × 365), one for the accurate 30 days. A common error is omitting the × 365.
4Calculating and interpreting inventory turnover
Building confidence• inventory turnover, efficiency, AO2
▼
Question
A retailer has cost of goods sold of 480,000andaverageinventoryof40,000. Calculate its inventory (stock) turnover in times per year and comment on the result. [4]
Step-by-step solution
Step 1
Apply inventory turnover (times) = cost of goods sold ÷ average inventory.
Inventoryturnover=480,000/40,000=12times
Step 2
Convert to days if helpful: 365 ÷ 12 ≈ 30 days — stock is held roughly a month before sale.
365/12=30.4days
Step 3
Interpret in context: the firm sells and replaces its entire stock 12 times a year. Whether this is 'good' depends on the sector — brisk for a furniture shop, but slow for fresh produce.
Answer
Inventory turnover = 480,000 ÷ 40,000 = 12 times per year (about every 30 days). The firm sells and replenishes its stock 12 times annually. This is efficient for a general retailer, tying up little cash in stock; but for a supermarket selling perishables it would be slow, and for a luxury-goods store it would be fast. Interpretation depends on the industry norm.
Examiner tip
AO2: 2 marks for the correct calculation (12 times), 2 for a contextual comment. Marks are lost for stating '12 times' with no interpretation.
5Calculating and interpreting creditor days
Building confidence• creditor days, efficiency, AO2
▼
Question
A manufacturer has trade payables of 60,000andcostofgoodssoldof500,000. Calculate its creditor (trade payable) days and explain ONE implication. [4]
Step-by-step solution
Step 1
Apply creditor days = trade payables ÷ cost of goods sold × 365.
Creditordays=60,000/500,000x365
Step 2
Compute.
=0.12x365=43.8=44days
Step 3
Explain an implication: taking 44 days to pay suppliers provides free short-term finance and eases cash flow, but paying too slowly could damage supplier relationships or forfeit early-payment discounts.
Answer
Creditor days = 60,000 ÷ 500,000 × 365 = 44 days. The firm takes on average 44 days to pay suppliers. Implication: this delay acts as free short-term finance, improving the firm's cash flow — but if suppliers expect payment in 30 days, taking 44 risks souring relationships and losing prompt-payment discounts.
Examiner tip
AO2: 2 marks for the accurate 44 days, 2 for a developed implication. Note this uses COST OF GOODS SOLD, not revenue.
6Interpreting a rise in gearing
Building confidence• gearing, interpretation, AO2
▼
Question
A firm's gearing rose from 35% to 58% over two years after taking a large bank loan to fund expansion. Explain TWO implications of this change. [6]
Step-by-step solution
Step 1
Note that the firm has moved from neutrally geared to highly geared (above 50%). It now depends heavily on debt.
Step 2
Implication 1 — higher financial risk: interest must be paid regardless of profit, so a downturn could threaten solvency, and a rise in interest rates would sharply increase costs.
Step 3
Implication 2 — reduced ability to borrow further: lenders now see the firm as riskier and may refuse additional finance or demand higher interest, constraining future investment. (Offsetting point: the expansion may raise profits enough to service the debt comfortably.)
Answer
At 58% the firm is now highly geared. First, its financial risk has risen: interest on the loan is a fixed cost that must be paid even if profits fall, and any increase in interest rates would raise costs significantly, squeezing cash flow. Second, its capacity to raise more finance is reduced — lenders will view it as higher-risk and may refuse further loans or charge more, limiting future flexibility. However, if the expansion succeeds and generates strong cash flow, the firm may service the debt easily and reward owners through gearing 'up'.
Examiner tip
AO2: up to 3 marks per developed implication. Best answers link the change to the expansion context and to interest rates.
7Recommending strategies to reduce gearing
Stretch• gearing, strategies, AO2, analysis
▼
Question
A highly geared firm (gearing 70%) wants to reduce its financial risk. Analyse TWO strategies it could use to lower its gearing. [6]
Step-by-step solution
Step 1
Strategy 1 — rights issue / new share issue: raise fresh equity and use the proceeds to repay debt, cutting the non-current-liabilities numerator and lowering gearing.
Step 2
Evaluate: reduces risk and interest costs, but dilutes existing owners' control and equity is a more expensive source of finance in the long run.
Step 3
Strategy 2 — retain more profit / debt-for-equity swap: reinvest retained earnings to pay down loans, or convert debt into shares. Both remove debt, but retaining profit is slow and cuts dividends, while a swap dilutes ownership.
Answer
One strategy is a rights issue: the firm sells new shares to existing shareholders and uses the cash to repay part of its loans. This directly reduces non-current liabilities and therefore gearing, cutting interest costs and financial risk — but it dilutes owners' control and equity is a costlier source over time. A second strategy is to retain more profit (or arrange a debt-for-equity swap) to pay down debt. Retaining earnings avoids dilution but is slow and reduces dividends; a swap removes debt immediately but hands lenders a stake in the firm. The best choice depends on how quickly the firm needs to cut risk and how much dilution owners will accept.
Examiner tip
AO2/analysis: reward two developed strategies with drawbacks. A strong answer shows each strategy's effect on the gearing formula.
8Efficiency ratios and the working-capital cycle
Stretch• efficiency, working capital, AO2, analysis
▼
Question
A firm has inventory days of 45, debtor days of 40 and creditor days of 30. Calculate the length of its cash conversion cycle and explain how it could shorten it. [6]
Step-by-step solution
Step 1
Cash conversion cycle = inventory days + debtor days − creditor days.
Cycle=45+40−30=55days
Step 2
Interpret: cash is tied up in operations for 55 days between paying suppliers and receiving cash from customers — a strain on liquidity.
Step 3
Explain improvements: reduce inventory days with JIT/better forecasting; reduce debtor days with tighter credit control or discounts; extend creditor days by renegotiating supplier terms — each shortens the cycle.
Answer
Cash conversion cycle = 45 + 40 − 30 = 55 days. Cash is tied up for 55 days from paying suppliers to collecting from customers. To shorten it the firm could: cut inventory days by adopting JIT and improving demand forecasting; cut debtor days through tighter credit control, prompt-payment discounts or factoring; and extend creditor days by negotiating longer supplier terms. Together these reduce the cash locked in working capital and improve liquidity — provided supplier relationships and sales are not harmed.
Examiner tip
AO2: 2 marks for the 55-day calculation, up to 4 for well-explained improvement strategies. Watch the SUBTRACTION of creditor days.
9Judging whether gearing is appropriate
Stretch• gearing, evaluation, context, AO3
▼
Question
A utility company (stable cash flows) has gearing of 60%; a tourism start-up has gearing of 60%. Explain why the same gearing may be appropriate for one but not the other. [6]
Step-by-step solution
Step 1
Establish that appropriateness of gearing depends on the reliability of cash flows and the industry, not the raw number.
Step 2
Utility: stable, predictable, regulated revenue means interest can be reliably serviced even in downturns, so 60% is manageable — and debt is cheap capital that keeps control with owners.
Step 3
Tourism start-up: volatile, seasonal, uncertain revenue plus the fragility of a new firm means fixed interest of that size is dangerous — a bad season could cause insolvency, and rate rises would hurt badly.
Answer
The same 60% gearing carries very different risk in the two firms. For the utility, revenue is stable, predictable and often regulated, so the company can reliably meet interest payments even in a downturn; high gearing is therefore appropriate, giving it cheap capital without diluting owners. For the tourism start-up, revenue is volatile and seasonal and the business is unproven, so committing to large fixed interest payments is dangerous — one poor season or a rise in interest rates could threaten solvency. Appropriateness of gearing depends on the stability of cash flows, the industry and the firm's maturity, not on the percentage alone.
Examiner tip
AO2/AO3 bridge: reward the point that context (cash-flow stability, industry, growth stage) determines whether gearing is appropriate.
Model Answers — Efficiency ratio analysis
High-scoring sample answers for efficiency ratio analysis on the Cambridge IGCSE paper, with examiner-style notes mapping each response to the mark scheme and assessment objectives.
Question 1
2 marks
State the formula for the gearing ratio. [2]
Model answer
Gearing ratio (%) = non-current liabilities ÷ capital employed × 100, where capital employed = equity + non-current liabilities.
Why this scores
AO1: one mark for the correct numerator/denominator, one for expressing it as a percentage (× 100). Using total liabilities loses the mark.
Question 2
2 marks
Define the term debtor (trade receivable) days. [2]
Model answer
Debtor days is an efficiency ratio measuring the average number of days a business takes to collect payment from its credit customers. It is calculated as trade receivables ÷ revenue × 365. A lower figure means cash is collected faster.
Why this scores
AO1: one mark for 'average time customers take to pay', one for linking it to cash collection/efficiency or the formula.
Question 3
2 marks
State ONE strategy a firm could use to improve its inventory (stock) turnover. [2]
Model answer
The firm could adopt a Just-In-Time (JIT) stock system, ordering stock only as it is needed. This reduces average inventory held, so stock is sold and replaced more times per year, raising inventory turnover. (Other valid answers: better demand forecasting, or clearing slow-moving lines through discounting.)
Why this scores
AO1: one mark for a valid strategy, one for a brief justification linking it to faster turnover.
Question 4
4 marks
A firm has non-current liabilities of 750,000andequityof250,000. Calculate its gearing ratio and comment on the result. [4]
Model answer
Capital employed = 250,000 + 750,000 = $1,000,000. Gearing = 750,000 ÷ 1,000,000 × 100 = 75%. This means 75% of the firm's long-term capital is financed by debt — the firm is very highly geared (well above the 50% threshold). This carries substantial financial risk: interest must be paid regardless of profit, the firm is highly exposed to any rise in interest rates, and lenders will be reluctant to provide further finance. It may need to raise equity to reduce this risk.
Why this scores
AO2: 2 marks for the correct 75% (method + accuracy), 2 for a contextual comment identifying it as highly geared and drawing out the risk implication.
Question 5
6 marks
A firm's trade receivables are 50,000,tradepayablesare36,000, revenue is 500,000andcostofgoodssoldis300,000. Calculate the debtor days and creditor days, and comment on the firm's working-capital management. [6]
Model answer
Debtor days = 50,000 ÷ 500,000 × 365 = 36.5 ≈ 37 days. Creditor days = 36,000 ÷ 300,000 × 365 = 43.8 ≈ 44 days. On average the firm collects from customers in 37 days but pays suppliers in 44 days. This is favourable for cash flow: it receives cash from customers about a week before it has to pay suppliers, so suppliers effectively help finance its working capital. Management appears reasonably tight on credit control (37 days is fairly prompt). However, if suppliers expect payment sooner than 44 days, the firm risks damaging relationships or losing early-payment discounts, so the position should be monitored.
Why this scores
AO2: 1 mark each for correct debtor days and creditor days (method and accuracy), up to 4 for interpretation comparing the two and commenting on cash flow. Note debtor days use REVENUE, creditor days use COGS.
Question 6
6 marks
Explain how an increase in interest rates could affect a highly geared business. [6]
Model answer
A highly geared business finances more than half of its capital employed through debt, so it carries large loan balances on which interest must be paid. When interest rates rise, the cost of servicing this debt increases — for variable-rate loans, the interest bill rises immediately, and any new borrowing becomes more expensive. This squeezes net profit and reduces cash available for other uses such as investment or dividends. In a severe case, rising interest costs combined with weak trading could push the firm towards being unable to meet repayments, threatening solvency. The firm may respond by reducing gearing (for example through a rights issue) or by fixing its interest rate. A low-geared firm, by contrast, would be far less affected. The impact therefore depends on how much debt the firm carries, whether its rates are fixed or variable, and how strong its cash flows are.
Why this scores
AO2: reward a clear chain of reasoning from rate rise → higher interest cost → lower profit/cash → higher insolvency risk, with the point that impact depends on the firm's circumstances.
Question 7
10 marks
Using ratio analysis, evaluate whether a fast-growing technology firm should increase its gearing from 30% to 60% to fund a major expansion. [10]
Model answer
Raising gearing from 30% to 60% would move the firm from low/neutral gearing to highly geared, using debt to fund expansion. There are strong arguments for it. Debt is generally cheaper than equity (interest is tax-deductible) and issuing shares would dilute the founders' control — a real concern for a young firm whose owners want to retain their vision. Debt also lets the firm act quickly to seize a growth opportunity, and if the expansion succeeds, the extra profit generated on borrowed money would 'gear up' returns to the existing owners without sharing them with new shareholders. For a firm confident of rapid growth, gearing up can accelerate value creation.
However, there are serious risks. At 60% gearing the firm faces large fixed interest payments that must be met whether or not the expansion delivers. Technology markets are volatile and revenues for a fast-growing but perhaps not-yet-profitable firm can be unpredictable, so committing to heavy interest is dangerous — a delay in the expansion paying off could cause a cash crisis. The firm would also become highly exposed to interest-rate rises, and having used up its borrowing capacity, it would find it hard to raise further finance if things went wrong. Ratio analysis has limits too: gearing is historic and says nothing about the quality of the expansion project, management capability or market conditions, so the decision cannot rest on the ratio alone.
On balance, whether the firm SHOULD gear up to 60% depends on the reliability of its forecast cash flows and the economic climate. If the expansion has predictable, contracted revenues and interest rates are low and stable, moderate additional debt is justified. But for a typical volatile tech firm facing rising rates, jumping straight to 60% is probably too aggressive; a smaller increase, or a mix of some debt and some equity, would fund growth while keeping financial risk manageable. The firm should base the decision on cash-flow forecasts and an investment appraisal of the expansion, not on gearing in isolation.
Why this scores
AO3: award to level 3 (8–10) only where both sides are developed with ratio understanding AND a justified, context-specific conclusion. Weaker answers assert 'high gearing is bad' without weighing the benefits of debt.
Question 8
10 marks
A retailer's inventory turnover has fallen from 10 times to 6 times a year and debtor days have risen from 25 to 45. Evaluate the seriousness of these changes for the business. [10]
Model answer
Both changes point to weakening efficiency in managing working capital, and together they could be serious. Inventory turnover falling from 10 to 6 times means stock now sits unsold for about 61 days rather than 37 — more cash is tied up in inventory, storage and obsolescence costs rise, and the fall may signal weaker demand or over-ordering. Debtor days rising from 25 to 45 means customers are taking far longer to pay, so cash is flowing in more slowly; this could reflect weak credit control or customers in financial difficulty. Combined, the two trends lengthen the cash conversion cycle and squeeze liquidity, which for a retailer with thin margins and regular supplier payments could threaten its ability to pay bills — a real short-term danger.
However, the changes must be judged in context before concluding they are critical. The slower stock turnover might be a deliberate strategy — for example holding wider ranges or premium stock that sells more slowly but at higher margin — and longer debtor days might reflect generous credit terms deliberately offered to win customers during expansion. It also matters how the figures compare with INDUSTRY norms and with competitors, and whether they are a one-off or a sustained trend; a single year's dip during, say, a recession may be less alarming than a persistent decline. Ratio analysis alone does not reveal the underlying cause.
Overall, the changes are a warning sign that should be taken seriously because they worsen liquidity, but their seriousness depends on the cause and the firm's cash position. If the firm still has healthy cash reserves and the changes reflect a chosen strategy, they may be acceptable; if they reflect poor management of a firm already short of cash, urgent action — tighter credit control and better stock management — is needed. The priority is to investigate the causes and monitor the trend rather than react to the ratios in isolation.

Question 9
10 marks
Evaluate the usefulness of gearing and efficiency ratios to a firm's stakeholders when assessing its financial health. [10]
Model answer
Gearing and efficiency ratios are valuable tools for a range of stakeholders. Gearing tells lenders and shareholders how much financial risk the firm carries: a bank deciding whether to grant a loan will be reassured by low gearing and wary of a highly geared applicant, while investors use it to judge the risk-return profile of their stake. Efficiency ratios — inventory turnover, debtor days and creditor days — reveal how well managers control working capital, which drives liquidity; suppliers can use creditor days to see how promptly they are likely to be paid, and managers use all three to spot problems such as slow-moving stock or poor credit control early. Because the ratios reduce complex accounts to comparable figures, they allow useful comparison over time (trend analysis) and against competitors (benchmarking), supporting evidence-based decisions.
Yet the ratios have important limitations. They are based on HISTORIC data and may not reflect the firm's current or future position, especially in a fast-changing market. They ignore QUALITATIVE factors that matter greatly to financial health — the quality of management, staff morale, brand strength, market share and the state of the economy. Different firms use different accounting policies (for example depreciation or inventory valuation methods), which distorts comparisons. A single ratio in isolation can also mislead: high gearing is not necessarily bad, and fast inventory turnover is not necessarily good, without industry context. Finally, the ratios can be affected by one-off events or 'window dressing' of the accounts.
Overall, gearing and efficiency ratios are useful but not sufficient. They give stakeholders a quick, comparable snapshot of financial risk and working-capital management and are an excellent starting point, but they should be used ALONGSIDE trend analysis, industry benchmarks and qualitative judgement rather than as a stand-alone verdict on financial health. Their usefulness is greatest when interpreted in context by a stakeholder who understands both the numbers and the business behind them.
Why this scores
AO3: strong answers balance clear benefits to named stakeholders against the well-known limitations of ratio analysis and conclude that ratios are necessary but not sufficient. Generic 'ratios are helpful' answers without limitations cap at level 2.
Key Formulae — Efficiency ratio analysis
The formulae you need to memorise for efficiency ratio analysis on the Cambridge IGCSE paper, with every variable defined in plain English and a note on when to use it.
To measure the % of capital employed financed by long-term debt (financial risk). Highly geared > 50%, low geared < 25%.
Example
400,000 ÷ 1,000,000 × 100 = 40%
Inventory (stock) turnover — times
▼
Inventory turnover=Average inventoryCost of goods sold
Averageinventory
(opening inventory + closing inventory) ÷ 2
When to use
To find how many times a year the firm sells and replaces its stock. A higher number = faster-selling stock.
Example
480,000 ÷ 40,000 = 12 times per year
Inventory (stock) turnover — days
▼
Inventory days=Cost of goods soldAverage inventory×365
365
days in the year — required to express turnover in days
When to use
To express stock turnover as the average number of days stock is held before sale. A lower number of days = faster-selling stock.
Example
40,000 ÷ 480,000 × 365 = 30 days
Debtor days (trade receivable days)
▼
Debtor days=RevenueTrade receivables×365
Tradereceivables
amount owed to the firm by credit customers
Revenue
annual sales revenue
When to use
To find the average number of days customers take to pay. Lower = cash collected faster (better for liquidity).
Example
30,000 ÷ 365,000 × 365 = 30 days
Creditor days (trade payable days)
▼
Creditor days=Cost of goods soldTrade payables×365
Tradepayables
amount the firm owes to its suppliers
Costofgoodssold
direct cost of the goods sold in the period
When to use
To find the average number of days the firm takes to pay suppliers. Higher = more free short-term finance, but risks supplier relationships.
Example
60,000 ÷ 500,000 × 365 = 44 days
Key Definitions and Keywords — Efficiency ratio analysis
Definitions to memorise and the exact keywords mark schemes credit for efficiency ratio analysis answers — sharpened from recent examiner reports for the 2026 Cambridge IGCSE sitting.
Gearing ratio
Examiner keyword▼
The proportion of a firm's capital employed that is financed by long-term debt (non-current liabilities) rather than equity, expressed as a percentage. A measure of financial risk.
Example
Non-current liabilities of 400,000oncapitalemployedof1,000,000 = 40% gearing.
The total long-term capital invested in a business, calculated as equity (share capital + reserves) plus non-current liabilities. It is the denominator in the gearing ratio.
A business whose gearing ratio is above 50%, meaning more than half of its capital employed is financed by long-term debt. Associated with higher financial risk.
The risk arising from a firm's use of debt: because interest and repayments are fixed obligations, high debt increases the chance the firm cannot meet its commitments, especially in a downturn or when interest rates rise.
Ratios that measure how well a business uses its resources and manages its working capital — including inventory turnover, debtor days and creditor days.
An efficiency ratio measuring how many times a year a firm sells and replaces its inventory (cost of goods sold ÷ average inventory), or equivalently the number of days stock is held.
Example
COGS 480,000÷averageinventory40,000 = 12 times per year.
An efficiency ratio measuring the average number of days a firm takes to collect payment from credit customers (trade receivables ÷ revenue × 365). Lower is generally better for cash flow.
An efficiency ratio measuring the average number of days a firm takes to pay its suppliers (trade payables ÷ cost of goods sold × 365). Higher provides free short-term finance but can strain supplier relationships.
The finance available for a firm's day-to-day operations, calculated as current assets minus current liabilities. Efficiency ratios show how well it is managed.
The number of days between paying suppliers and receiving cash from customers, calculated as inventory days + debtor days − creditor days. A shorter cycle eases liquidity.
Example
45 + 40 − 30 = 55 days of cash tied up in operations.
The raising of new equity by offering additional shares to existing shareholders, often used to repay debt and reduce gearing. It dilutes ownership if not all take up their rights.
An arrangement in which a firm's lenders exchange the debt they are owed for shares in the company, removing debt from the balance sheet and lowering gearing but diluting existing owners.
A stock-management method in which inventory is ordered and received only as needed for production or sale, reducing average inventory held and improving inventory turnover.
Example
A firm using JIT holds minimal stock, raising turnover and freeing up cash.
The management of the credit a firm extends to customers — setting terms, checking creditworthiness and chasing payment — used to reduce debtor days and protect cash flow.
Common Mistakes and Misconceptions — Efficiency ratio analysis
The traps other students keep falling into on efficiency ratio analysis questions — taken from recent Cambridge IGCSE examiner reports and mark schemes — and how to avoid them.
✕Assuming high gearing is always bad.
IB Diploma Programme Business Management Guide (first teaching 2022, first assessment 2024)
▼
Why it happens
Students learn that debt = risk and apply it as an absolute rule, ignoring the benefits of debt and the firm's context.
How to avoid it
Remember that high gearing can be appropriate for firms with stable cash flows (utilities) or during low-interest expansion, because debt is cheap and keeps control with owners. Always judge gearing against the industry, growth stage and interest-rate climate.
✕Confusing debtor days with creditor days (and their formulae).
IB Diploma Programme Business Management Guide (first teaching 2022, first assessment 2024)
▼
Why it happens
The two ratios look similar and both express a number of days, so students swap the numerators and denominators.
How to avoid it
Debtor days = trade receivables ÷ REVENUE × 365 (money owed TO us by customers). Creditor days = trade payables ÷ COST OF GOODS SOLD × 365 (money WE owe suppliers). Note the different denominators.
✕Forgetting to multiply by 365 on the 'days' ratios.
IB Diploma Programme Business Management Guide (first teaching 2022, first assessment 2024)
▼
Why it happens
Students compute the fraction (e.g. receivables ÷ revenue) and stop, forgetting it must be scaled to a number of days.
How to avoid it
Any ratio expressed in DAYS must be × 365. Check your answer is a sensible number of days (typically 20–90), not a tiny decimal like 0.08.
✕Using total liabilities instead of non-current liabilities in gearing.
IB Diploma Programme Business Management Guide (first teaching 2022, first assessment 2024)
▼
Why it happens
Students grab the 'liabilities' figure from the balance sheet without separating out current (short-term) liabilities.
How to avoid it
Gearing uses NON-CURRENT (long-term) liabilities only, over capital employed (equity + non-current liabilities). Exclude current liabilities such as trade payables and overdrafts.
✕Stating a ratio without interpreting it in context.
IB Diploma Programme Business Management Guide (first teaching 2022, first assessment 2024)
▼
Why it happens
Students treat these as maths questions and stop once they have the number, missing the AO2/AO3 marks.
How to avoid it
Always follow a calculation with a comment: what does this figure mean for THIS firm, in ITS industry, compared with previous years or competitors? Marks are awarded for interpretation, not just arithmetic.
✕Treating a fast inventory turnover or high creditor days as automatically 'good'.
IB Diploma Programme Business Management Guide (first teaching 2022, first assessment 2024)
▼
Why it happens
Students memorise 'lower/higher is better' rules without considering the downside of each.
How to avoid it
Very fast turnover can cause stock-outs and lost sales; very high creditor days can anger suppliers and lose discounts. Judge each ratio against what is normal and sustainable for the specific business.
