📚 Ratio Analysis for IGCSE AQA Business: Key Points | IGCSE AQA 商务：比率分析考点精讲
Ratio analysis is a powerful tool used by businesses and investors to evaluate a company’s financial performance and health. By comparing one figure from the financial statements with another, ratios turn raw data into meaningful insights. For IGCSE AQA Business students, mastering ratio analysis is essential for interpreting accounts, assessing profitability, liquidity, efficiency, and gearing, and making informed recommendations for improvement.
比率分析是企业与投资者用来评估公司财务业绩和健康状况的强大工具。通过将财务报表中的一个数字与另一个数字进行比较，比率将原始数据转化为有意义的洞察。对于 IGCSE AQA 商务学生来说，掌握比率分析对于解读账目、评估盈利能力、流动性、效率及杠杆水平，并提出合理的改进建议至关重要。
1. What is Ratio Analysis? | 什么是比率分析？
Ratio analysis involves calculating financial ratios from a firm’s income statement and statement of financial position. These ratios allow stakeholders to compare performance over time, against competitors, and against industry benchmarks. It helps answer key questions about how well a business is being managed.
比率分析涉及根据企业的利润表和财务状况表计算财务比率。这些比率让利益相关者能够跨时间、与竞争对手以及行业基准进行比较。它有助于回答关于企业经营状况的关键问题。
Ratios are classified into groups: profitability, liquidity, efficiency, and gearing. Each group focuses on a different aspect of business performance, making it easier to diagnose strengths and weaknesses.
比率被分为几类：盈利能力、流动性、效率和杠杆比率。每一类关注企业经营业绩的不同方面，以便更容易诊断优势与劣势。
2. Profitability Ratios: Gross Profit Margin | 盈利能力比率：毛利率
The gross profit margin measures how effectively a business turns revenue into gross profit. It shows the percentage of sales revenue remaining after paying direct costs of production (cost of sales).
毛利率衡量企业将营业收入转化为毛利润的效率。它显示在支付直接生产成本（销售成本）后剩余的销售收入百分比。
Gross Profit Margin (%) = (Gross Profit ÷ Sales Revenue) × 100
毛利率 (%) = (毛利 ÷ 销售收入) × 100
A high gross profit margin suggests the business is adding significant value and has strong pricing power, or it controls direct costs well. A low margin may indicate high cost of sales, low selling prices, or intense competition. To improve it, a firm can raise prices if demand is inelastic, negotiate cheaper supplies, or improve production efficiency.
高毛利率表明企业增加了大量价值且具有强大的定价能力，或者很好地控制了直接成本。低毛利率可能意味着销售成本高、售价低或竞争激烈。为了提高毛利率，企业可以在需求缺乏弹性时提价、协商更便宜的供应或提高生产效率。
3. Profitability Ratios: Net Profit Margin | 盈利能力比率：净利率
The net profit margin reveals the overall profitability of a business after all expenses, including overheads and interest, have been deducted. It indicates how well a company controls its total costs.
净利率揭示了企业在扣除所有费用（包括日常管理费用和利息）后的整体盈利能力。它表明企业控制总成本的能力如何。
Net Profit Margin (%) = (Net Profit before tax ÷ Sales Revenue) × 100
净利率 (%) = (税前净利润 ÷ 销售收入) × 100
A rising net profit margin signals strong cost management and possibly growing market power. A declining margin may be caused by excessive overheads or falling sales. Improvement strategies include cutting administrative expenses, relocating to cheaper premises, or reducing interest costs by paying down debt.
净利率上升表明成本管理能力强，市场力量可能也在增长。净利率下降可能是由过高的间接费用或销售额下降造成的。改进策略包括削减管理费用、搬迁至更便宜的场所或通过偿还债务减少利息成本。
4. Profitability Ratios: Return on Capital Employed (ROCE) | 盈利能力比率：已用资本回报率
ROCE measures how efficiently a business generates profit from the capital invested in it. It is a fundamental indicator of financial performance and is often used by investors to compare companies.
ROCE 衡量企业从投入的资本中产生利润的效率。它是财务业绩的基本指标，常被投资者用于比较不同公司。
ROCE (%) = (Operating Profit ÷ Capital Employed) × 100
ROCE (%) = (营业利润 ÷ 已用资本) × 100
Capital employed is usually calculated as total assets minus current liabilities, or as total equity plus non-current liabilities. A high ROCE means the business is using its funds wisely; a low ROCE might suggest inefficient use of assets or too much idle capital. To boost ROCE, firms can increase operating profit without raising capital employed, or dispose of underperforming assets.
已用资本通常计算为总资产减去流动负债，或总权益加非流动负债。高 ROCE 意味着企业明智地使用资金；低 ROCE 可能表明资产使用效率低或闲置资本过多。为了提高 ROCE，企业可以在不增加已用资本的情况下提高营业利润，或处置表现不佳的资产。
5. Liquidity Ratios: Current Ratio | 流动性比率：流动比率
Liquidity ratios assess a firm’s ability to meet its short-term debts as they fall due. The current ratio compares current assets with current liabilities.
流动性比率评估企业偿付到期短期债务的能力。流动比率将流动资产与流动负债进行比较。
Current Ratio = Current Assets ÷ Current Liabilities
流动比率 = 流动资产 ÷ 流动负债
A result between 1.5:1 and 2:1 is generally considered healthy, though it depends on the industry. A ratio below 1 may indicate potential cash flow problems, while a ratio that is too high might imply inefficient use of assets, such as excessive inventory. Improving the current ratio can involve reducing current liabilities through longer loan repayment terms or converting stock into cash through sales.
结果在 1.5:1 到 2:1 之间通常被认为是健康的，尽管这取决于行业。比率低于 1 可能表示潜在的现金流问题，而比率过高可能意味着资产使用效率低下，例如库存过多。改善流动比率可以通过延长贷款还款期限减少流动负债，或通过销售将库存转化为现金。
6. Liquidity Ratios: Acid Test Ratio | 流动性比率：速动比率
The acid test ratio (quick ratio) is a stricter measure of liquidity because it excludes inventory, which may not be quickly convertible to cash. It focuses on cash, trade receivables, and marketable securities.
速动比率（酸性测试比率）是一种更严格的流动性衡量指标，因为它排除了可能无法快速转换为现金的存货。它侧重于现金、应收账款和有价证券。
Acid Test Ratio = (Current Assets – Inventory) ÷ Current Liabilities
速动比率 = (流动资产 – 存货) ÷ 流动负债
An acid test ratio of around 1:1 is often satisfactory. A lower value raises concerns about immediate liquidity, especially if suppliers demand quick payment. To improve it, a business can speed up collection from trade receivables or delay cash outflows, for example by negotiating longer credit terms with suppliers.
速动比率约为 1:1 通常令人满意。较低的值会引起对即时流动性的担忧，尤其是在供应商要求快速付款的情况下。为提高该比率，企业可以加快应收账款回收或延迟现金流出，例如通过协商延长供应商信用期。
7. Efficiency Ratios: Inventory Turnover | 效率比率：存货周转率
Inventory turnover measures how many times a company sells and replaces its inventory over a period. It reflects stock control efficiency.
存货周转率衡量一家公司在一定时期内销售和更换库存的次数。它反映了库存控制效率。
Inventory Turnover = Cost of Sales ÷ Average Inventory
存货周转率 = 销售成本 ÷ 平均库存
A high turnover indicates strong sales and efficient stock management, reducing storage costs and the risk of obsolescence. A low turnover suggests slow-moving items or overstocking, which ties up cash. To increase turnover, firms can run promotional sales, adjust product mix, or improve demand forecasting.
高周转率表明销售强劲且库存管理高效，降低了仓储成本和过时风险。低周转率表明商品滞销或库存积压，这会占用现金。为了提高周转率，企业可以进行促销、调整产品组合或改进需求预测。
8. Efficiency Ratios: Trade Receivables Days | 效率比率：应收账款周转天数
This ratio measures the average number of days it takes a business to collect money from its credit customers. It evaluates credit control effectiveness.
该比率衡量企业从赊销客户收回款项的平均天数。它评估信用控制的有效性。
Trade Receivables Days = (Trade Receivables ÷ Credit Sales) × 365
应收账款周转天数 = (应收账款 ÷ 赊销收入) × 365
A lower number of days means faster cash inflow, improving liquidity. A high figure may point to poor credit control, late payments, or overly generous terms. Reduction can be achieved by offering discounts for early settlement, tightening credit checks, or using factoring services.
天数越少意味着现金流入越快，改善了流动性。数值高可能表明信用控制不力、付款延迟或条件过于宽松。可通过提供提前付款折扣、加强信用审查或使用保理服务来缩短天数。
9. Efficiency Ratios: Trade Payables Days | 效率比率：应付账款周转天数
Trade payables days show how long, on average, a business takes to pay its suppliers. It is a measure of how the firm uses short-term credit.
应付账款周转天数显示企业平均需要多长时间支付供应商货款。它衡量企业如何利用短期信用。
Trade Payables Days = (Trade Payables ÷ Credit Purchases) × 365
应付账款周转天数 = (应付账款 ÷ 赊购金额) × 365
A longer payment period helps cash flow because the business retains cash longer. However, excessively delaying payments can damage supplier relationships and lead to loss of credit terms. An optimal balance must be found; monitoring this ratio helps managers decide when to pay earlier for discounts.
较长的付款期有助于现金流，因为企业持有现金的时间更长。然而，过度延迟付款可能损害供应商关系并导致失去信用条件。必须找到最佳平衡；监测此比率有助于管理人员决定何时提前付款以获取折扣。
10. Gearing Ratio (Debt to Equity) | 杠杆比率（资产负债率）
The gearing ratio examines the long-term financial structure of a business by comparing borrowed capital with owners’ capital. High gearing means more reliance on debt.
杠杆比率通过比较借入资本与所有者资本来考察企业的长期财务结构。高杠杆意味着对债务的依赖更大。
Gearing (%) = (Non-current Liabilities ÷ Capital Employed) × 100
杠杆比率 (%) = (非流动负债 ÷ 已用资本) × 100
A gearing ratio above 50% is often considered high, implying greater financial risk because interest must be paid regardless of profits. A low-geared firm has more security but may miss growth opportunities. Management can lower gearing by repaying long-term loans or issuing new shares, while raising it through additional borrowing for expansion.
杠杆比率高于 50% 通常被认为是高的，意味着财务风险较大，因为无论利润如何都必须支付利息。低杠杆企业更安全，但可能错失增长机会。管理层可以通过偿还长期贷款或发行新股来降低杠杆，通过额外借款扩张来提高杠杆。
11. Limitations of Ratio Analysis | 比率分析的局限性
Ratios are based on historical financial data and may not reflect current market conditions or future prospects. They only provide a snapshot of past performance.
比率基于历史财务数据，可能无法反映当前市场状况或未来前景。它们只提供过去业绩的一个快照。
Different accounting policies—such as depreciation methods or inventory valuation—can distort comparisons between firms. Inflation can also make figures misleading. Furthermore, ratios ignore non-financial factors like employee morale, brand reputation, and market changes. Therefore, ratios should be used alongside qualitative analysis.
不同的会计政策——例如折旧方法或存货估值——可能扭曲公司间的比较。通货膨胀也会使数据产生误导。此外，比率忽略非财务因素，如员工士气、品牌声誉和市场变化。因此，比率应与定性分析结合使用。
External benchmarks, such as industry averages, are essential for meaningful evaluation. A ratio in isolation rarely tells the full story.
外部基准，如行业平均值，对于有意义的评估至关重要。孤立的比率很少能说明全部情况。
12. Exam Tips for Ratio Analysis | 比率分析考试技巧
Always show the formula and your workings step by step. The AQA mark scheme rewards clear substitution of numbers even if the final answer is slightly wrong.
一定要逐步展示公式和计算过程。即使最终答案略有错误，AQA 评分方案也会奖励清晰的数字代入。
State the unit: percentages for profit margins and ROCE, ratios for liquidity (e.g., 1.8:1), days for efficiency ratios, and percentages for gearing. Missing units can lose marks.
注明单位：利润率和 ROCE 用百分比，流动性比率用比值（如 1.8:1），效率比率用天数，杠杆比率用百分比。缺少单位可能失分。
When evaluating, always compare the ratio with the previous year, a competitor, or industry data. Explain what an increase or decrease means for the business and suggest realistic actions to improve it. Use connectives like ‘this reveals that…’ and ‘therefore the business should…’ to develop analysis.
评估时，始终将比率与上一年、竞争对手或行业数据进行比较。解释比率的上升或下降对企业的意义，并提出现实的改进措施。使用诸如 ‘这表明…’ 和 ‘因此企业应该…’ 的连接词来展开分析。
Finally, balance your answer by mentioning limitations, showing you understand that ratios are just one tool among many for decision making.
最后，通过提及局限性来平衡你的答案，表明你理解比率只是众多决策工具中的一种。
