📚 Understanding Income Statements | 理解损益表

An income statement is a financial report that shows a business’s revenue, costs and profit over a specific period of time, usually one year. It is one of the most important documents used by managers, shareholders and lenders to judge business performance.

损益表是一份财务报表，显示企业在特定时期（通常为一年）内的收入、成本和利润。它是管理者、股东和贷款人用来判断企业经营业绩的最重要文件之一。

1. What Is an Income Statement? | 什么是损益表？

The income statement, also called a profit and loss account, summarises the trading activities of a business. It records money earned from selling goods or services and subtracts all the costs incurred to earn that money.

损益表，也称为利润表或损益账户，概括了企业的交易活动。它记录通过销售商品或服务赚取的资金，并减去为赚取这些资金而发生的一切成本。

For Cambridge IGCSE Business Studies, you need to understand three main profit figures: gross profit, operating profit or profit for the year. These appear in a standard income statement layout.

对于剑桥 IGCSE 商务研究课程，你需要理解三个主要利润数字：毛利、营业利润或年度利润。它们出现在标准损益表格式中。

2. Purpose of Income Statements | 损益表的用途

Income statements are prepared for several reasons. First, they help managers see whether the business is making a profit or a loss. Second, they allow shareholders to decide whether to keep investing. Third, banks use them to assess whether a business can repay loans.

编制损益表有几个原因。第一，帮助管理者了解企业是盈利还是亏损。第二，让股东决定是否继续投资。第三，银行用损益表评估企业能否偿还贷款。

Income statements also help in comparing performance over time and against competitors. A consistent increase in profit often signals business growth and good financial control.

损益表还有助于比较不同时期的业绩以及与竞争对手的表现。利润持续增长通常表明企业增长良好、财务控制得当。

3. Key Components | 主要组成部分

An income statement contains key items: revenue, cost of sales, gross profit, expenses and profit for the year. Each item has a specific meaning and calculation.

损益表包含关键项目：收入、销售成本、毛利、费用和年度利润。每一项都有特定的含义和计算方法。

Revenue: the total amount received from selling goods or services before any costs are deducted.

收入：在扣除任何成本之前，通过销售商品或服务获得的总金额。
Cost of sales: the direct cost of producing or buying the goods sold.

销售成本：生产或购买已售商品的直接成本。
Gross profit: revenue minus cost of sales.

毛利：收入减去销售成本。
Expenses: indirect costs such as rent, wages and advertising.

费用：间接成本，如租金、工资和广告。
Profit for the year: gross profit minus expenses. This is the final profit after all costs are deducted.

年度利润：毛利减去费用，这是扣除所有成本后的最终利润。

4. Gross Profit Calculation | 毛利计算

Gross profit measures how efficiently a business sells its products. It focuses only on the direct cost of producing the goods.

毛利衡量企业销售产品的效率，它只关注生产商品的直接成本。

Gross profit = Revenue − Cost of sales

毛利 = 收入 − 销售成本

Cost of sales is often calculated as opening inventory plus purchases minus closing inventory. This ensures the profit matches the goods actually sold in the period.

销售成本通常按期初存货加上采购额减去期末存货计算。这样可以确保利润与当期实际销售的商品相匹配。

Cost of sales = Opening inventory + Purchases − Closing inventory

销售成本 = 期初存货 + 采购额 − 期末存货

5. Profit for the Year | 年度利润

Profit for the year, also called net profit, is the amount left after deducting all other expenses from gross profit. These expenses include rent, salaries, insurance, marketing and depreciation.

年度利润，也称为净利润，是从毛利中扣除所有其他费用后剩余的金额。这些费用包括租金、工资、保险、营销和折旧。

Profit for the year = Gross profit − Expenses

年度利润 = 毛利 − 费用

Profit for the year is important because it shows the overall profitability of the whole business. It is used to calculate dividends for shareholders and retained earnings for reinvestment.

年度利润很重要，因为它显示整个企业的整体盈利能力。它用于计算股东分红和用于再投资的留存收益。

6. Example of an Income Statement | 损益表示例

The table below shows a typical income statement layout. Notice that costs are shown in brackets, meaning they are subtracted.

下表显示典型的损益表格式。注意成本用括号表示，表示需要减去。

Income Statement for the year ended 31 December	$
Revenue	100,000
Cost of sales	(60,000)
Gross profit	40,000
Expenses	(15,000)
Profit for the year	25,000

In this example, the business turned 100,000 of revenue into 25,000 of final profit. This is a profit margin of 25%.

在这个示例中，企业将 100,000 收入转化为 25,000 最终利润，即利润率为 25%。

7. Gross Profit Margin | 毛利率

Businesses do not just look at profit in absolute terms; they also calculate profit margins to compare performance. The gross profit margin shows gross profit as a percentage of revenue.

企业不仅看利润的绝对数额，还会计算利润率来比较业绩。毛利率表示毛利占收入的百分比。

Gross profit margin = (Gross profit ÷ Revenue) × 100%

毛利率 =（毛利 ÷ 收入）× 100%

Using the example above, gross profit margin = (40,000 ÷ 100,000) × 100% = 40%. This means for every dollar of revenue, 40 cents are left after paying direct costs.

使用上面的示例，毛利率 =（40,000 ÷ 100,000）× 100% = 40%。这意味着每 1 元收入中，在支付直接成本后剩下 40 分。

8. Profit Margin for the Year | 年度利润率

The profit margin for the year (net profit margin) is another important ratio. It measures how much of each dollar of revenue remains after all expenses.

年度利润率（净利润率）是另一个重要比率。它衡量每 1 元收入在扣除所有费用后还剩多少。

Profit margin for the year = (Profit for the year ÷ Revenue) × 100%

年度利润率 =（年度利润 ÷ 收入）× 100%

In the example, profit margin for the year = (25,000 ÷ 100,000) × 100% = 25%. A higher margin usually means the business is efficient in controlling costs.

在示例中，年度利润率 =（25,000 ÷ 100,000）× 100% = 25%。较高的利润率通常意味着企业在控制成本方面效率较高。

9. Uses of Income Statements | 损益表的用途分析

There are many groups who use income statements. Shareholders use them to decide whether to keep or sell their shares. Managers use them to identify areas where costs are too high. Lenders use them to check creditworthiness.

有许多群体使用损益表。股东用它决定继续持有还是出售股份；管理者用它识别成本过高的领域；贷款人用它检查信誉。

Comparing income statements over several years helps a business spot trends. If gross profit margin falls but revenue stays the same, the business may be paying more for materials. If expenses rise sharply, managers should investigate why.

将多年损益表进行比较有助于企业发现趋势。如果毛利率下降而收入保持不变，企业可能正在支付更高的材料费用。如果费用急剧上升，管理者应调查原因。

10. Limitations of Income Statements | 损益表的局限性

Despite their usefulness, income statements have limitations. First, they show historical data and may not predict future performance. Second, profit is affected by accounting decisions such as depreciation methods and inventory valuation.

尽管损益表很有用，但也有局限性。第一，它显示的是历史数据，可能无法预测未来业绩。第二，利润会受到会计决策的影响，如折旧方法和存货计价方法。

Third, profit is not the same as cash. A business can make a profit but still have no cash if customers have not paid yet. Therefore, income statements should be read together with the statement of financial position and cash flow information.

第三，利润不等于现金。如果客户尚未付款，企业可能虽有利润但仍缺少现金。因此，损益表应与财务状况表及现金流量信息一起阅读。

11. Exam Tips for IGCSE Business | IGCSE 商务考试提示
