IB Business Management HL - Unit 3 Finance and Accounts

3.6 Efficiency Ratio Analysis | IB Business Management HL

Efficiency ratio analysis helps students move beyond profit and liquidity into the daily operating discipline of a business: how quickly inventory is sold, how fast credit customers pay, how long the business takes to pay suppliers, and how risky its financing structure is. In IB Business Management HL, these ratios should be used as decision-making evidence, not as isolated calculations.

What Is Efficiency Ratio Analysis?

Efficiency ratio analysis is the use of financial ratios to judge how effectively a business manages its resources. Profitability ratios ask whether the business is earning enough profit. Liquidity ratios ask whether it can pay short-term debts. Efficiency ratios ask whether day-to-day resources are being used well. They focus on the speed and quality of business operations: inventory movement, credit collection, supplier payment and the use of finance.

Efficiency matters because profit does not automatically mean strong cash flow. A business may sell goods profitably but wait months to collect payment from customers. A retailer may report high current assets, but if most of those assets are slow-moving inventory, the business may still struggle to pay suppliers. A company may grow quickly, but if growth is funded by too much debt, interest payments may create financial risk. Efficiency ratios reveal these practical problems.

In exam answers, efficiency ratios should never be treated as universal "good" or "bad" numbers. A high stock turnover may be efficient for a supermarket but unrealistic for a furniture retailer. Long creditor days may support cash flow, but they may also damage supplier relationships. Low debtor days may improve cash, but strict credit terms may reduce sales. Ratio analysis is useful only when interpreted with context, trend data, industry norms and stakeholder priorities.

Main Efficiency Ratios and Formulas

The exact formula wording can vary by textbook and exam context, so always use the formula expected by your teacher or given in the question. The core idea is consistent: compare a resource with the activity that uses or creates it. The result should then be interpreted as a speed, period, turnover rate or financial risk indicator.

Stock Turnover

Stock turnover, also called inventory turnover, measures how quickly a business sells or uses its inventory. It is especially important for retailers, wholesalers, manufacturers, restaurants and any business that holds stock. The basic formula is cost of goods sold / average stock. If cost of goods sold is $600,000 and average stock is $100,000, stock turnover is 6 times per year. This means the business sells or replaces its average stock about six times during the year.

A higher stock turnover usually suggests that inventory is moving quickly. This can reduce storage costs, reduce waste, reduce the risk of obsolete stock and free up cash. Supermarkets, fast-fashion retailers and restaurants often need high stock turnover because products may spoil, go out of fashion or take up valuable shelf space. Fast stock movement can also show strong demand and effective purchasing.

However, higher is not always better. If stock turnover is too high, the business may not hold enough inventory to meet demand. Stockouts can lead to lost sales, frustrated customers and damaged reputation. A business that keeps stock levels too low may also lose bulk purchase discounts or rely on expensive emergency deliveries. Good inventory management balances efficiency with service reliability.

A low stock turnover may suggest overstocking, weak demand, poor product choice, ineffective marketing or slow production processes. Inventory ties up cash. If a business holds too much stock, money that could be used for wages, suppliers, loan repayments or investment is trapped in unsold goods. Slow-moving stock may also require discounting, which can reduce gross profit margin.

Stock Turnover Period

Some questions express inventory efficiency as a period in days. The stock turnover period formula is average stock / cost of goods sold x 365. It estimates how many days stock is held before being sold or used. This is the same idea as stock turnover, but the interpretation is easier for some students because it gives a time period.

If average stock is $60,000 and cost of goods sold is $360,000, the stock turnover period is $60,000 / $360,000 x 365 = 60.8 days. The business holds stock for about 61 days on average. A fall from 80 days to 61 days may show improved inventory management. But if it falls to 10 days and customers often cannot find products, the improvement may be too aggressive.

Inventory periods vary greatly by industry. A bakery wants very short inventory periods because goods are perishable. A car dealership may have longer inventory periods because each unit is expensive and customers compare options carefully. A furniture retailer may hold stock longer than a grocery store. In IB answers, always interpret stock ratios using the type of business.

Debtor Days

Debtor days measure how long, on average, a business takes to collect money from credit customers. The formula is debtors / credit sales x 365. Debtors are also called trade receivables or accounts receivable. They represent customers who have bought on credit but have not yet paid.

Debtor days matter because sales revenue is not the same as cash received. A business can record a sale and profit before cash arrives. If customers take too long to pay, the business may struggle to pay wages, suppliers, rent and loan interest. This creates liquidity pressure even when sales are high.

Lower debtor days generally suggest better credit control and faster cash collection. This improves cash flow and reduces the risk of bad debts. Managers may reduce debtor days by checking customer creditworthiness, issuing invoices quickly, offering early payment discounts, sending reminders, using electronic payment systems or refusing further credit to late-paying customers.

But very low debtor days are not automatically good. Strict credit terms may reduce sales if customers expect time to pay. In business-to-business markets, offering trade credit may be necessary to compete. A small supplier that demands immediate payment may lose customers to rivals offering 30 or 60 days of credit. The right debtor days figure depends on industry practice, customer relationships and bargaining power.

Creditor Days

Creditor days measure how long, on average, a business takes to pay suppliers. The formula is creditors / credit purchases x 365. Creditors are also called trade payables or accounts payable. They represent amounts owed to suppliers for goods or services already received.

Longer creditor days can support cash flow because the business keeps cash for longer before paying suppliers. This may help fund working capital, especially if the business collects cash from customers before supplier payments are due. For example, a retailer that sells goods quickly for cash and pays suppliers after 45 days may have a helpful cash cycle.

However, delaying payment too long can damage supplier relationships. Suppliers may withdraw credit, demand payment in advance, reduce delivery priority, remove discounts or charge late-payment fees. In extreme cases, unpaid suppliers may stop supplying altogether, which can disrupt operations. A business that improves cash flow by pressuring suppliers may create long-term operational risk.

Very low creditor days may show that the business pays suppliers quickly. This can build trust and secure early payment discounts. But it may also mean the business is not using available trade credit effectively. Paying too early can put unnecessary pressure on cash flow, especially if customers pay slowly.

The Cash Conversion Cycle

Stock turnover, debtor days and creditor days are connected. Together they help explain the cash conversion cycle: the time between paying suppliers for inventory and receiving cash from customers. A business that holds inventory for a long time, gives customers generous credit and pays suppliers quickly will need more working capital. A business that sells inventory quickly, collects cash fast and negotiates reasonable supplier credit will have a shorter cash cycle.

A simple way to think about the cycle is: stock days plus debtor days minus creditor days. This is not always required in IB questions, but it helps interpretation. If inventory is held for 40 days, customers pay after 30 days and suppliers are paid after 45 days, the business may need to finance about 25 days of the operating cycle. If inventory days rise to 80 and debtor days rise to 60, the cash pressure increases sharply.

Working capital management is therefore not only about having enough cash. It is about managing the timing of cash flows. The business must coordinate purchasing, production, selling, invoicing, collection and payment. Efficiency ratios help identify where cash is being delayed or wasted.

Gearing Ratio

Gearing measures the extent to which a business is financed by loan capital compared with total long-term capital. A common formula is loan capital / capital employed x 100. Loan capital normally includes long-term borrowing. Capital employed may be calculated as equity plus non-current liabilities, or total assets minus current liabilities, depending on the information provided.

A highly geared business relies heavily on debt. This can be risky because interest and repayments must be paid even if sales fall or profits decline. Higher gearing can make lenders cautious and may reduce financial flexibility. If interest rates rise, a highly geared business may face higher finance costs. If cash flow weakens, it may struggle to meet repayment obligations.

However, debt is not automatically bad. Borrowing can help a business expand, buy productive assets, enter new markets or invest in technology. If borrowed funds generate returns greater than the cost of borrowing, gearing can increase shareholder returns. A business with very low gearing may be financially cautious, but it may also be missing growth opportunities.

Students should avoid saying that a gearing ratio above 50 percent is always bad. It is often considered high, but interpretation depends on industry, interest rates, stability of cash flow, asset security, growth prospects and economic conditions. A utility company with stable cash flows may safely carry more debt than a start-up with uncertain revenue.

Debt/Equity Ratio

The current IB HL subject brief highlights debt/equity ratio analysis as an HL-only finance topic. Debt/equity ratio is closely related to gearing because both examine financial risk from borrowing. A common formula is total debt / total equity. A result of 1:1 means the business has the same amount of debt as equity. A result of 2:1 means debt is twice equity.

Debt/equity ratio helps stakeholders judge financial structure. Lenders use it to assess repayment risk. Owners use it to consider whether expansion is being funded through debt or shareholder funds. Managers use it to evaluate whether the business has enough financial flexibility for future investment. A rising debt/equity ratio can show increasing reliance on borrowing, which may increase risk but also support growth.

In an HL answer, debt/equity should be interpreted with profitability and cash flow. A business with high debt/equity but strong and stable cash flows may be able to manage repayments. A business with low debt/equity but weak profitability may still be unattractive to investors. Financial structure is only one part of the judgement.

Insolvency and Bankruptcy

Insolvency occurs when a business cannot pay its debts as they fall due, or when liabilities exceed assets depending on the definition used. In practical business analysis, the cash-flow meaning is especially important: a business is in trouble if it cannot meet immediate obligations such as wages, supplier invoices, tax payments, interest or loan repayments.

Bankruptcy is a formal legal process in many jurisdictions, often used for individuals. Companies may instead enter liquidation, administration, receivership or restructuring depending on local law. The key exam point is that insolvency is a financial condition, while bankruptcy or liquidation is a legal process. Not every insolvent business immediately disappears. Some businesses negotiate with creditors, sell assets, raise new finance, restructure debt or reduce costs to survive.

Efficiency ratios can provide warning signs. Rising debtor days may show cash is being delayed. Falling stock turnover may show inventory is not selling. Very high creditor days may show the business is stretching supplier credit because it lacks cash. Rising gearing may show dependence on borrowing. None of these ratios proves insolvency by itself, but together they can signal growing financial stress.

Worked Example: Full Efficiency Ratio Set

Consider a wholesaler with the following annual data:

• Cost of goods sold: $900,000
• Average stock: $150,000
• Credit sales: $1,200,000
• Debtors: $180,000
• Credit purchases: $720,000
• Creditors: $120,000
• Loan capital: $400,000
• Capital employed: $1,000,000

The wholesaler turns over stock six times per year. This may be reasonable, but interpretation depends on the type of goods. If goods are seasonal or perishable, the business may need faster turnover. Debtor days of about 55 suggest customers take nearly two months to pay. This could be normal in some business-to-business markets, but it ties up cash. Creditor days of about 61 means the business pays suppliers slightly later than it collects from customers, which may support cash flow if suppliers accept those terms. Gearing of 40 percent suggests moderate debt risk.

A strong judgement would not call the business healthy or unhealthy from one ratio. It would ask whether debtor days are rising or falling, whether supplier terms allow 60 days, whether inventory is fast-moving, whether loan interest is affordable and whether competitors operate with similar figures. The business may be managing working capital reasonably, but if debtor days rise further or suppliers shorten credit terms, liquidity pressure could increase.

Improving Stock Turnover

A business can improve stock turnover by forecasting demand more accurately, reducing over-ordering, using just-in-time purchasing, improving merchandising, discounting slow-moving goods, redesigning product ranges, using better inventory systems or improving supplier reliability. Each method has trade-offs. Reducing inventory lowers holding costs, but it may increase stockout risk. Discounting clears stock, but it may reduce gross profit margin and train customers to wait for promotions.

For manufacturers, improving stock turnover may involve lean production, better scheduling, fewer defects and faster movement of raw materials through production. For retailers, it may involve choosing the right product mix and managing seasonal demand. For restaurants, it may involve menu design, supplier coordination and waste control. The best action depends on the type of inventory and why stock is moving slowly.

Improving Debtor Days

To reduce debtor days, a business can invoice faster, set clearer credit terms, check customer credit history, offer early payment discounts, use automated reminders, charge late payment fees, factor receivables or refuse further credit to overdue customers. These actions can improve cash flow and reduce bad debts.

However, stricter credit control can affect sales and relationships. If customers are used to 60-day credit terms, reducing terms to 15 days may push them to competitors. A business must balance cash flow safety against customer satisfaction and competitiveness. The best approach may be targeted: stricter terms for risky customers, normal terms for reliable customers and incentives for early payment.

Improving Creditor Days

Improving creditor days does not always mean increasing them. The goal is to manage supplier payments effectively. A business may negotiate longer payment terms, align payment dates with customer receipts, use electronic payment scheduling or consolidate purchases with fewer suppliers. These actions can support cash flow.

But delaying supplier payments beyond agreed terms is risky. Suppliers may reduce credit limits, stop deliveries, remove discounts or demand cash in advance. In industries where supplier reliability affects product quality and service speed, damaging supplier relationships can hurt operations. A business should not use suppliers as an emergency bank without considering long-term consequences.

Managing Gearing and Debt Risk

A business can reduce gearing by repaying debt, issuing shares, retaining profits, selling assets and using the proceeds to reduce borrowing, or avoiding additional loans. Lower gearing may reduce interest costs and financial risk. It can also reassure lenders and investors during uncertain economic conditions.

A business can deliberately increase gearing by borrowing to finance expansion. This may be sensible if interest rates are low, cash flows are stable and expected returns are strong. Borrowing also allows owners to keep control because debt does not normally dilute ownership. The risk is that repayments are fixed and must be made even if the investment underperforms.

HL evaluation should connect gearing to the external environment. Rising interest rates make high gearing more dangerous. Recession can reduce sales and make repayments harder. Inflation may increase costs. Strong demand and stable cash flows may make debt more manageable. Again, context controls the judgement.

Stakeholder Impact of Efficiency Ratios

Managers use efficiency ratios to diagnose operating problems. Rising stock days may trigger inventory reviews. Rising debtor days may trigger credit control action. Rising creditor days may show cash pressure or a deliberate strategy to preserve cash. Rising gearing may affect financing plans and risk management.

Owners and shareholders care because efficiency affects profit, cash flow and business value. Poor inventory management ties up capital and may reduce returns. Slow collection from customers increases working capital needs. Excessive debt can increase risk and reduce future dividends if profits are used to pay interest.

Lenders care because efficiency ratios help assess repayment ability. A business with slow debtor collection, high inventory and high gearing may be riskier than a business with fast cash conversion and moderate debt. Suppliers care because creditor days show whether the business pays promptly. Employees may be affected if poor efficiency leads to cost cutting or job insecurity. Customers may be affected if inventory cuts create stockouts or if tighter credit terms reduce purchasing flexibility.

Efficiency Ratios in Different Business Types

Retail Businesses

Retailers depend heavily on stock turnover. Fast-moving inventory supports cash flow and reduces storage costs. However, retailers must hold enough stock to meet customer demand. A supermarket has different inventory expectations from a luxury furniture store. Debtor days may be low for cash or card-based retailers, while creditor days may be an important source of supplier finance.

Manufacturing Businesses

Manufacturers may hold raw materials, work in progress and finished goods. Stock turnover is more complex because inventory passes through production stages. Debtor days matter if customers are wholesalers or retailers buying on credit. Creditor days matter because manufacturers often depend on reliable suppliers. Gearing may be higher because factories and machinery require long-term capital investment.

Service Businesses

Many service businesses hold little or no inventory, so stock turnover may be less relevant. Debtor days can still matter if clients pay after work is completed. Consulting firms, agencies and contractors often face cash flow pressure when clients delay payment. Gearing may be lower if the business does not need many physical assets, but this depends on the industry.

Technology Businesses

Technology businesses may have low physical inventory but significant receivables if they sell to corporate clients. Gearing can be risky for early-stage technology businesses because cash flows may be uncertain. However, established technology firms may use debt safely if subscription revenue is predictable. Ratio interpretation must consider intangible assets, growth stage and cash burn.

Limitations of Efficiency Ratio Analysis

Efficiency ratios are useful, but they have limitations. First, they are based on accounting data, which may be historical and affected by accounting policies. Year-end figures may not represent average conditions during the year. A retailer's stock level immediately before a major sales season may look high, while the same level after the season may look excessive.

Second, ratios need comparison. Stock turnover of six times per year means little without knowing the industry, product type, seasonality and competitor performance. Debtor days of 45 may be good in one industry and weak in another. Creditor days of 60 may be normal for large retailers but damaging for a small business relying on local suppliers.

Third, ratios can create misleading incentives. Managers told to improve stock turnover may cut inventory too far. Managers told to reduce debtor days may pressure customers and lose sales. Managers told to increase creditor days may damage supplier trust. Managers told to reduce gearing may reject profitable investment opportunities. Ratios should guide judgement, not replace it.

Fourth, ratios ignore qualitative information. Supplier reliability, customer loyalty, employee skill, brand reputation, product quality, ethical practices and sustainability may not appear in efficiency calculations. A business may choose slightly slower stock turnover because it stocks a wider product range to improve customer satisfaction. A social enterprise may offer generous credit terms to support community customers, even though debtor days rise.

Interpreting Efficiency Ratios Together

Efficiency ratios become more useful when they are interpreted together rather than one by one. A single ratio may identify a possible issue, but a combination of ratios can reveal the underlying business pattern. For example, a fall in stock turnover may show slow inventory movement. If debtor days are also rising, the business may be selling slowly and collecting cash slowly. If creditor days are rising at the same time, the business may be using supplier credit to cover a working capital shortage. If gearing is also high, the risk becomes more serious because the business must also meet interest and repayment obligations.

One useful exam approach is to ask whether the ratios point to an operating problem, a cash flow problem or a financing problem. Stock turnover often points to operating efficiency and demand. Debtor days point to credit control and customer payment behaviour. Creditor days point to supplier payment strategy and short-term cash pressure. Gearing points to long-term financial risk. When several ratios worsen together, the answer should explain how the problems reinforce each other.

Consider a manufacturer whose stock turnover falls from 7 times to 4 times, debtor days rise from 35 to 65, creditor days rise from 40 to 75 and gearing rises from 42 percent to 62 percent. The business may be experiencing several linked problems. Slow stock turnover suggests inventory is not moving quickly, perhaps because demand has weakened or production is poorly matched to orders. Rising debtor days suggest customers are taking longer to pay, increasing cash tied up in receivables. Rising creditor days suggest the business may be delaying supplier payments to preserve cash. Rising gearing suggests the business has taken on more borrowing, which increases interest commitments. Taken together, these ratios could indicate growing financial stress, not just isolated inefficiency.

However, the same ratio pattern could have a different explanation if the context changes. If the manufacturer has just launched a major expansion, stock may have increased deliberately to prepare for expected demand. Debtor days may rise because the business offered longer credit terms to enter a new market. Gearing may rise because the business borrowed to buy new machinery. In this case, the ratios still show higher risk, but the judgement is not automatically negative. The key question is whether the expansion is likely to generate enough future sales and cash flow to justify the short-term pressure.

Efficiency ratio evaluation should therefore include time. A temporary worsening may be acceptable if it supports a clear strategy and is expected to reverse. A long-term worsening trend is more concerning. If stock turnover has been falling for three years, debtor days have risen every year and creditor days are above supplier terms, the business may have structural problems. If gearing has also risen, lenders and investors may question whether management is relying on borrowing to cover weak operations.

It is also useful to separate controllable and uncontrollable causes. Poor credit control, inaccurate demand forecasting, weak inventory systems and late invoicing are internal problems. Recession, supply chain disruption, customer financial difficulties and rising interest rates are external pressures. The recommended action depends on the cause. Internal problems may require management changes, better systems or stricter policies. External pressures may require contingency planning, renegotiation, pricing adjustments or changes to supplier and customer terms.

A strong final judgement might say: "The business appears to have a working capital problem because inventory is moving more slowly, customers are paying later and supplier payments are being delayed. This is made riskier by rising gearing, as debt repayments add pressure to cash flow. However, the final judgement depends on whether these changes are temporary effects of expansion or signs of weak demand and poor financial control." This kind of answer is stronger than simply saying that each ratio is high or low.

HL Strategic Judgement: Efficiency, Risk and Sustainability

At Higher Level, the strongest answers link efficiency ratios to strategic choices. A business should not simply maximize every ratio. It should decide what level of inventory, credit, supplier payment and debt fits its objectives, market conditions and stakeholder relationships. Efficiency is not the same as short-term cost cutting. True efficiency supports sustainable performance.

For example, a business may improve stock turnover by holding less inventory. This releases cash and reduces storage costs. But if customers cannot find products, revenue may fall. A business may reduce debtor days by demanding faster payment. This improves liquidity, but it may reduce customer loyalty. A business may increase creditor days to preserve cash. This helps short-term working capital, but it may damage supplier trust. A business may increase gearing to fund growth. This can improve returns, but it raises financial risk.

In Paper 3-style social enterprise contexts, efficiency ratios should be interpreted with social impact. A social enterprise may deliberately give customers longer payment periods because it serves low-income groups. It may pay suppliers quickly to support small local producers. It may hold extra inventory to ensure access to essential goods. These choices may look less efficient in narrow financial terms, but they may support the mission. The key question is whether the organization remains financially sustainable while delivering impact.

A strong HL conclusion is conditional. It might say: "The rise in debtor days is a concern because it weakens cash flow, but it may be acceptable if the business is deliberately offering credit to secure long-term contracts and bad debts remain low." Or: "The increase in gearing is risky because interest rates are rising, but it may be justified if the borrowed funds finance assets that will increase future profit and cash flow." Conditional judgement shows mature business analysis.

Worked IB-Style Scenarios

Common Student Mistakes

The first common mistake is assuming higher is always better. Higher stock turnover can be good, but too high may mean stockouts. Higher creditor days can support cash flow, but too high can damage supplier relationships. Higher gearing can support growth, but too high increases financial risk.

The second mistake is ignoring units. Stock turnover may be expressed as times per year or days. Debtor days and creditor days are expressed in days. Gearing is expressed as a percentage. Debt/equity is expressed as a ratio. Using the wrong format weakens the answer.

The third mistake is interpreting ratios without a benchmark. A debtor days figure of 45 is not automatically good or bad. Compare it with credit terms, previous years, competitors or industry norms.

The fourth mistake is treating insolvency and bankruptcy as the same. Insolvency is a financial condition. Bankruptcy, liquidation or administration are legal processes that depend on jurisdiction and business type.

The fifth mistake is forgetting stakeholders. Efficiency decisions affect suppliers, customers, employees, owners, lenders and communities. A decision that improves one ratio may create problems for another stakeholder group.

Exam Technique for Efficiency Ratio Analysis

For calculation questions, write the formula, substitute the numbers and include the correct unit. If the question gives average stock, use it. If it gives opening and closing stock, calculate average stock as (opening stock + closing stock) / 2. If the question uses credit sales or credit purchases, do not use total sales or total purchases unless instructed.

For interpretation questions, use a structured sentence. For example: "Debtor days have increased from 35 to 60, meaning customers are taking longer to pay. This may weaken cash flow because cash is tied up in receivables. If the increase is caused by poor credit control, the business should improve collection procedures. However, if it reflects a deliberate decision to attract large reliable customers, the effect may be acceptable."

For evaluation questions, compare ratios and finish with a judgement. A business with poor stock turnover and rising debtor days may face working capital pressure. If creditor days are also rising, it may be relying on suppliers to finance operations. If gearing is high as well, the business may face a serious financial risk. The strongest answers bring ratios together rather than treating each one separately.

Key Takeaways

Efficiency ratios show how well a business manages resources. Stock turnover measures inventory movement. Debtor days measure customer payment speed. Creditor days measure supplier payment timing. Gearing and debt/equity measure financial structure and borrowing risk. These ratios link final accounts to cash flow, working capital and strategic risk.

There is no single perfect ratio. The best result depends on industry, business model, customer behaviour, supplier power, economic conditions and strategy. A ratio that looks efficient in one business may be dangerous in another. Interpretation requires comparison and context.

Insolvency is a warning that the business cannot meet debts when due. Bankruptcy, liquidation or administration are legal processes that may follow depending on jurisdiction and business type. Efficiency ratios can help identify early warning signs before a crisis becomes formal.

For IB Business Management HL, the goal is not only to calculate ratios accurately. The goal is to use ratios to make informed business judgements about efficiency, cash flow, risk, stakeholders and long-term sustainability.

Frequently Asked Questions

What is the simplest definition of efficiency ratios?

Efficiency ratios measure how effectively a business uses and manages resources such as inventory, receivables, payables and capital.

Is high stock turnover always good?

No. High stock turnover can show strong sales and efficient inventory management, but if it is too high it may cause stockouts, lost sales and customer dissatisfaction.

Why are debtor days important?

Debtor days are important because they show how quickly credit customers pay. If debtor days are high, cash is tied up in receivables and liquidity may weaken.

Why are creditor days important?

Creditor days show how long the business takes to pay suppliers. Longer creditor days may support cash flow, but excessive delays can damage supplier relationships.

What does high gearing mean?

High gearing means a large proportion of capital is financed by borrowing. It can increase financial risk because interest and repayments must be made even if profits fall.

How should I evaluate efficiency ratios in an exam?

Use the formula accurately, compare the result with a benchmark, suggest causes, explain consequences and make a judgement using business context and stakeholders.

Final Summary

Efficiency ratio analysis is about the speed, discipline and risk of business finance. A business that sells inventory quickly, collects from customers promptly, pays suppliers responsibly and manages debt carefully is more likely to have strong working capital and financial flexibility. A business with slow inventory, rising debtors, stretched creditors and high gearing may be profitable on paper but vulnerable in practice.

The main exam skill is interpretation. Do not stop after calculating stock turnover, debtor days, creditor days or gearing. Explain what the number means, compare it with the right benchmark, connect it to cash flow and stakeholders, and finish with a balanced judgement. That is what turns ratio analysis from arithmetic into business management.
