Ratio Analysis | 比率分析

📚 Ratio Analysis | 比率分析

Ratio analysis is a powerful quantitative tool that helps businesses evaluate their financial health. By comparing figures from the income statement and statement of financial position, ratios reveal a company’s liquidity, profitability, and efficiency, allowing managers, investors, and lenders to make informed decisions.

比率分析是一种强大的量化工具，有助于企业评估其财务健康状况。通过比较利润表和财务状况表中的数据，比率能够揭示公司的流动性、盈利能力和效率，使管理者、投资者和贷款人能够做出明智的决策。

1. What is Ratio Analysis? | 什么是比率分析？

Ratio analysis involves calculating and interpreting financial ratios to assess a firm’s performance over time and against competitors. It transforms raw accounting numbers into meaningful relationships, such as how many pounds of current assets are available to cover each pound of short-term debt.

比率分析涉及计算和解读财务比率，以评估企业随时间推移的表现以及与竞争对手的比较。它将原始的会计数字转化为有意义的关系，例如每英镑短期债务有多少英镑流动资产来覆盖。

Ratios on their own are simply numbers. Their true value lies in making comparisons: to the same business in previous years, to budgeted figures, and to industry averages or direct competitors.

单独的比率只是数字。它们的真正价值在于进行比较：与同一企业往年的数据、预算数据以及行业平均水平或直接竞争对手进行比较。

2. Liquidity Ratios: Current Ratio | 流动性比率：流动比率

Liquidity ratios measure a business’s ability to meet its short-term debts as they fall due. The current ratio is the most basic liquidity measure. It is calculated using the formula:

流动性比率衡量企业偿还到期短期债务的能力。流动比率是最基本的流动性指标。其计算公式如下：

Current Ratio = Current Assets ÷ Current Liabilities

For example, if a bakery has current assets of £40,000 and current liabilities of £20,000, its current ratio is 2:1. This means it has £2 of current assets for every £1 of current liabilities. A ratio below 1:1 signals potential cash flow problems, while a very high ratio might indicate that too much cash is tied up in stock or debtors.

例如，如果一家面包店的流动资产为40,000英镑，流动负债为20,000英镑，其流动比率为2:1。这意味着每1英镑流动负债有2英镑流动资产支持。比率低于1:1表明可能存在现金流问题，而比率过高可能意味着过多现金被积压在存货或应收账款中。

3. Liquidity Ratios: Acid Test Ratio | 流动性比率：速动比率

The acid test ratio (or quick ratio) is a stricter measure of liquidity because it excludes stock, which may not be quickly converted into cash. The formula is:

速动比率（亦称酸性测试比率）是更严格的流动性指标，因为它排除了可能无法迅速变现的存货。计算公式为：

Acid Test Ratio = (Current Assets − Stock) ÷ Current Liabilities

If the bakery above holds £10,000 of its current assets as stock, its acid test ratio becomes (£40,000 − £10,000) ÷ £20,000 = 1.5:1. A result around 1:1 is generally seen as healthy, showing the business can pay its short-term debts without relying on selling stock.

如果上述面包店的流动资产中有10,000英镑为存货，其速动比率为（40,000英镑 – 10,000英镑）÷ 20,000英镑 = 1.5:1。结果在1:1左右通常被认为是健康的，表明企业无需依赖销售存货就能偿还短期债务。

4. Profitability Ratios: Gross Profit Margin | 盈利能力比率：毛利率

Profitability ratios show how effectively a business converts sales revenue into profit. The gross profit margin measures the percentage of revenue remaining after paying for the cost of goods sold. The formula is:

盈利能力比率显示企业将销售收入转化为利润的效率。毛利率衡量在支付销售成本后剩余收入的百分比。计算公式为：

Gross Profit Margin (%) = (Gross Profit ÷ Revenue) × 100

A clothing retailer with revenue of £500,000 and a gross profit of £200,000 has a gross profit margin of 40%. This means 40p in every £1 of sales contributes to covering expenses and generating net profit. A falling margin could indicate rising supplier costs or the need to discount prices.

一家服装零售商销售收入为500,000英镑，毛利润为200,000英镑，其毛利率为40%。这意味着每1英镑销售收入中有40便士用于支付费用和产生净利润。毛利率下降可能表明供应商成本上升或需要打折销售。

5. Profitability Ratios: Net Profit Margin | 盈利能力比率：净利率

The net profit margin reveals what percentage of revenue remains as profit after all business expenses have been deducted. It is calculated as:

净利率揭示在扣除所有业务费用后，剩余利润占收入的百分比。其计算公式为：

Net Profit Margin (%) = (Net Profit ÷ Revenue) × 100

Using the same retailer, if net profit is £50,000, the net profit margin is 10%. This ratio is a key indicator of overall expense control. Comparing gross profit margin and net profit margin helps businesses see whether expenses are growing too fast.

同样以该零售商为例，如果净利润为50,000英镑，净利率为10%。该比率是整体费用控制的关键指标。比较毛利率和净利率有助于企业了解费用是否增长过快。

6. 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 money invested in it. It is a fundamental measure of long-term profitability. The formula is:

已用资本回报率衡量企业如何有效地利用投入的资金创造利润。它是衡量长期盈利能力的基本指标。计算公式为：

ROCE (%) = (Net Profit ÷ Capital Employed) × 100

Capital employed is often calculated as total equity plus non-current liabilities, or as total assets minus current liabilities. If a business has a net profit of £80,000 and capital employed of £400,000, its ROCE is 20%. This means for every £1 invested, the business earns 20p in profit. A higher ROCE is generally better, showing the business is using its funds productively.

已用资本通常计算为总权益加非流动负债，或总资产减流动负债。如果一家企业的净利润为80,000英镑，已用资本为400,000英镑，其已用资本回报率为20%。这意味着每投入1英镑，企业赚取20便士利润。回报率越高通常越好，表明企业正有效利用其资金。

7. Using Ratios for Comparison | 使用比率进行比较

Ratios become meaningful only when compared. The three main forms of comparison are:

比率只有通过比较才有意义。三种主要的比较形式是：

Historical comparison: Examining the same business’s ratios over several years to spot trends, such as improving liquidity or declining profitability.
同业比较：对同一企业多年的比率进行审视，以发现趋势，例如流动性改善或盈利能力下降。
Inter-firm comparison: Comparing ratios with competitors or the industry average to see if the business is performing above or below the norm.
企业间比较：将比率与竞争对手或行业平均水平进行比较，以了解企业表现是高于还是低于正常水平。
Budget comparison: Comparing actual ratios against budgeted targets helps managers identify where performance deviated from plans.
预算比较：将实际比率与预算目标进行比较，有助于管理者发现实际表现与计划出现偏差的地方。

No single ratio tells the complete story; a set of ratios should be examined together to get a full picture of business health.

没有一个比率能说明全部情况；应综合考察一组比率，以全面了解企业的健康状况。

8. Limitations of Ratio Analysis | 比率分析的局限性

Despite its usefulness, ratio analysis has important limitations that GCSE students must know:

尽管比率分析很有用，但它有重要局限性，GCSE学生必须了解：

Ratios are only as reliable as the underlying accounting data. If the figures are outdated or based on estimates, the ratios will be misleading.
比率仅与其所依据的会计数据一样可靠。如果数据已过时或基于估计，比率将产生误导。
Differences in accounting policies between firms (e.g. depreciation methods or stock valuation) can make inter-firm comparisons invalid.
会计政策差异（如折旧方法或存货估值）可能使企业间的比较无效。
Ratios ignore non-financial factors such as employee morale, brand reputation, and changing market conditions.
比率忽略了非财务因素，如员工士气、品牌声誉和不断变化的市场状况。
Inflation can distort year-on-year comparisons, making older data less comparable.
通货膨胀可能扭曲同比比较，使旧数据的可比性降低。
A single ratio is a snapshot; seasonal businesses may show very different ratios at different times of the year.
单一比率只是一个快照；季节性企业在一年中的不同时间可能显示大不相同的比率。

9. Typical Ratio Values and What They Indicate | 典型比率值及其含义

While “ideal” ratios vary by industry, some general benchmarks are useful for analysis:

虽然“理想”比率因行业而异，但一些通用基准对分析很有用：

Ratio / 比率	Common benchmark / 常见基准	Interpretation / 解读
Current Ratio / 流动比率	1.5:1 to 2:1	Below 1:1 signals liquidity risk; too high may be inefficient.
Acid Test Ratio / 速动比率	0.7:1 to 1:1	Stricter test; shows ability to pay without selling stock.
Gross Profit Margin / 毛利率	Varies widely / 差异大	Higher is better; compare to industry average.
Net Profit Margin / 净利率	10%–20% typical / 10%–20% 典型	Shows overall expense control; falling margin worries investors.
ROCE / 已用资本回报率	Above bank interest rate / 高于银行利率	A higher ROCE makes the business attractive to investors.
