1. Profitability Ratios | 盈利能力比率

Profitability ratios assess a business’s ability to generate earnings relative to its revenue, assets, and equity. These metrics are fundamental for comparing performance across periods and against competitors.

盈利能力比率评估企业相对于其收入、资产和权益创造收益的能力。这些指标对于跨期比较业绩以及与竞争对手进行比较至关重要。

Gross Profit Margin shows the percentage of sales revenue remaining after covering the direct cost of goods sold. A higher margin indicates better control over production costs.

毛利率显示在覆盖所售商品的直接成本后剩余的销售收入百分比。较高的毛利率表明对生产成本有更好的控制。

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

Net Profit Margin accounts for all operating expenses, interest, and taxes, providing a clear picture of overall profitability from every pound of revenue generated.

净利润率考虑了所有运营费用、利息和税金，清晰展示了每一英镑收入产生的整体盈利能力。

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

Return on Capital Employed (ROCE) evaluates how efficiently a company uses its long-term capital. It is a crucial metric for investors and managers monitoring use of equity and debt.

运用资本回报率 (ROCE) 评估公司使用其长期资本的效率。它是投资者和管理者监测股权和债务使用情况的关键指标。

ROCE = (Operating Profit ÷ Capital Employed) × 100

where Capital Employed = Total Assets − Current Liabilities or Equity + Non-current Liabilities. A strong ROCE signals effective use of all invested funds.

其中运用资本 = 总资产 − 流动负债，或股权 + 非流动负债。强劲的 ROCE 表明所有投入资金得到了有效利用。

2. Liquidity Ratios | 流动性比率

Liquidity ratios measure a firm’s ability to meet short-term obligations as they fall due. They are vital for creditors and managers concerned with cash health and working capital management.

流动性比率衡量企业偿还到期短期债务的能力。它们对关注现金健康状况和营运资金管理的债权人及管理者至关重要。

Current Ratio compares total current assets to current liabilities, giving a broad view of liquidity. A ratio above 1.0 suggests adequate short-term coverage, though ideal levels differ by sector.

流动比率将总流动资产与流动负债进行比较，提供一个总体的流动性视角。比率高于 1.0 表明短期覆盖充足，但理想水平因行业而异。

Current Ratio = Current Assets ÷ Current Liabilities

Acid Test Ratio (Quick Ratio) excludes inventories from current assets to test immediate liquidity, because stock can be difficult to convert to cash quickly.

速动比率（酸性测试比率）从流动资产中剔除库存以测试即刻的流动性，因为存货可能难以快速变现。

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

3. Efficiency Ratios | 效率比率

Efficiency ratios reveal how well a business utilises its assets and manages its working capital. Strong efficiency typically supports healthy cash flow and profitability.

效率比率揭示企业如何有效利用其资产和管理营运资金。高效率通常支撑健康的现金流和盈利能力。

Inventory Turnover measures how many times a firm sells and replaces its inventory over a period. A higher turnover indicates leaner, more responsive inventory management.

库存周转率衡量企业在一个时期内销售和补充库存的次数。较高的周转率表示更精益、更敏捷的库存管理。

Inventory Turnover = Cost of Sales ÷ Average Inventory

where Average Inventory = (Opening Inventory + Closing Inventory) ÷ 2. This ratio can also be expressed as number of days: 365 ÷ Turnover.

其中平均库存 = (期初库存 + 期末库存) ÷ 2。该比率也可表示为天数：365 ÷ 周转次数。

Trade Receivable Days shows the average time taken to collect payment from credit customers. Fewer days improve cash flow.

贸易应收款天数显示从赊销客户收取款项的平均时间。天数越少，现金流状况越好。

Trade Receivable Days = (Trade Receivables ÷ Credit Sales) × 365

Trade Payable Days indicates how long a business takes to pay its suppliers. Longer days can ease short-term cash outflows but may strain supplier relationships.

贸易应付款天数表明企业向供应商付款的时长。天数越长可缓解短期现金流出，但可能影响供应商关系。

Trade Payable Days = (Trade Payables ÷ Credit Purchases) × 365

Asset Turnover assesses how effectively a firm generates revenue from its asset base. A higher figure points to greater operational efficiency.

资产周转率评估企业从其资产基础中产生收入的有效性。数值越高意味着运营效率越高。

Asset Turnover = Revenue ÷ Net Assets

4. Gearing & Leverage Ratios | 杠杆比率

Gearing ratios examine the proportion of a business’s capital that comes from debt. High gearing can amplify returns but also increases financial risk.

杠杆比率考察企业资本中来自债务的比例。高杠杆可以放大回报，但也增加财务风险。

Gearing Ratio compares non-current liabilities to total capital employed. It is a key measure of long-term financial stability.
