Income Statements | 损益表

📚 Income Statements | 损益表

An income statement is one of the most important financial documents for any business. It summarises the revenues earned and the expenses incurred over a specific accounting period, usually a year. By matching revenues with the costs of generating them, the income statement reveals whether the business has made a profit or suffered a loss. For IGCSE Business Studies, you need to understand its key components, how to calculate gross and net profit, and why this statement matters to different stakeholders.

损益表是任何企业最重要的财务文件之一。它总结了在特定会计期间（通常为一年）内获得的收入和发生的费用。通过将收入与产生收入的成本进行配比，损益表反映了企业是实现了利润还是发生了亏损。对于IGCSE商务课程，你需要理解其主要组成部分、如何计算毛利和净利润，以及该报表为何对不同的利益相关者如此重要。

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

An income statement, also known as a profit and loss account, is a financial statement that shows a business’s financial performance over a period of time. Unlike a balance sheet which captures a moment in time, the income statement records flows of revenue and expenses. It answers the fundamental question: has the business been profitable during this accounting period?

损益表，又称利润表，是显示企业在一段时间内财务业绩的财务报表。与反映某一时点状况的资产负债表不同，损益表记录的是收入和费用的流量。它回答了一个根本性问题：企业在本会计期间是否盈利？

The income statement follows the accruals concept, meaning revenues are recorded when they are earned, not necessarily when cash is received, and expenses are matched to the revenues they helped generate. This provides a more accurate picture of profitability than simply looking at cash inflows and outflows.

损益表遵循应计制概念，即收入在赚取时记录，而不一定在收到现金时记录，费用则与它们帮助产生的收入相配比。这比单纯看现金流入流出能更准确地反映盈利能力。

2. Key Components of an Income Statement | 损益表的主要组成部分

A standard income statement is built from several core building blocks. Understanding each component helps you analyse a business’s performance effectively.

一张标准的损益表由几个核心组成部分构成。理解每一个部分能帮助你有效分析企业业绩。

The main components are:

主要组成部分如下：

Revenue (Sales turnover) – income from selling goods or services.
Cost of sales – the direct costs of producing or purchasing the goods sold.
Gross profit – revenue minus cost of sales.
Expenses (Overheads) – operating costs not directly tied to production, such as rent and salaries.
Net profit – the final profit after all expenses, interest and tax have been deducted.

收入（销售额） – 销售商品或服务获得的收入。
销售成本 – 生产或采购所售商品的直接成本。
毛利 – 收入减去销售成本。
费用（间接费用） – 与生产不直接相关的经营成本，如租金和工资。
净利润 – 扣除所有费用、利息和税金后的最终利润。

3. Revenue or Sales Turnover | 收入或销售额

Revenue is the total amount of money a business earns from its trading activities before any deductions. For a retailer, this is the cash taken from selling goods; for a service provider, it is the fees charged to clients. Revenue appears at the very top of the income statement, which is why it is often called the ‘top line’.

收入是企业在任何扣除之前从其经营活动中赚取的总金额。对零售商来说，这是销售商品收取的现金；对服务提供商来说，这是向客户收取的费用。收入出现在损益表的最顶端，因此常被称为“顶线”。

Revenue growth is a key indicator of business expansion, but it does not guarantee profitability. A company can have high sales yet still make a loss if its costs are not controlled properly.

收入增长是企业扩张的关键指标，但并不保证盈利。如果成本控制不当，一家公司销售额很高却仍可能亏损。

4. Cost of Sales | 销售成本

Cost of sales represents the direct costs incurred in getting the goods ready for sale. For a manufacturing business, this includes raw materials, direct labour, and factory overheads. For a retailer, it is the cost of buying the products that were sold during the period. The formula to calculate cost of sales is:

销售成本表示为使货物达到可售状态而发生的直接成本。对制造企业来说，这包括原材料、直接人工和工厂间接费用。对零售商来说，它是当期已售产品的购买成本。计算销售成本的公式如下：

Cost of Sales = Opening Inventory + Purchases − Closing Inventory

销售成本 = 期初存货 + 采购 − 期末存货

Opening inventory is the unsold stock brought forward from the previous period. Purchases are additional stock bought during the year. Closing inventory is what remains unsold at the end of the period. Subtracting closing inventory ensures that costs are matched only to the goods that were actually sold.

期初存货是从上一期间结转下来的未售库存。采购是本年度额外购入的存货。期末存货是期末仍未售出的部分。减去期末存货确保了成本仅与实际售出的商品相匹配。

5. Gross Profit Calculation | 毛利计算

Gross profit is the difference between sales revenue and the cost of sales. It measures how efficiently a business turns raw materials or purchased goods into sales income, before accounting for operating expenses. The calculation is straightforward:

毛利是销售收入与销售成本之间的差额。它衡量企业在扣除经营费用之前，将原材料或采购商品转化为销售收入的效率。计算方法非常简单：

Gross Profit = Sales Revenue – Cost of Sales

毛利 = 销售收入 − 销售成本

A high gross profit suggests the business either charges high prices relative to its buying costs or achieves strong sales volumes with a reasonable mark-up. A low or negative gross profit signals that the core trading activity is not sustainable. Companies monitor gross profit closely because it reflects their basic pricing and procurement strategies.

高毛利表明企业要么相对于采购成本定价较高，要么以合理的加成实现了很大的销售量。低毛利或负毛利则意味着核心交易活动不可持续。企业密切关注毛利，因为它反映了其基本定价和采购策略。

6. Expenses: Operating and Non-operating | 费用：经营性费用与非经营性费用

Expenses are the overheads and other costs a business must pay to operate, not directly tied to each unit of product. They are deducted from gross profit to calculate net profit. Typical operating expenses include rent, salaries, electricity, advertising, insurance, and depreciation of non-current assets.

费用是企业运营必须支付的间接成本和其他开支，与每个产品单位不直接相关。这些费用从毛利中扣除以计算净利润。典型的经营费用包括租金、工资、电费、广告费、保险费和非流动资产的折旧。

Non-operating expenses are costs not linked to the main trading activity, such as interest paid on loans. Interest is shown separately because it arises from financing decisions rather than core operations. This separation helps users distinguish operating performance from financing effects.

非经营费用是与主要经营活动无关的成本，例如贷款利息支出。利息单独列示，因为它源于融资决策而非核心运营。这种区分有助于使用者将经营业绩与融资影响分开。

7. Net Profit Before and After Tax | 税前与税后净利润

Net profit is often called the ‘bottom line’ because it sits at the bottom of the income statement. There are two important versions:

净利润通常被称为“底线”，因为它位于损益表的最底行。有两个重要的版本：

Net profit before tax is calculated by subtracting total expenses (including interest) from gross profit. It shows the profit generated from all activities before the government takes its share.

税前净利润通过从毛利中减去总费用（包括利息）计算得出。它显示了在政府拿走税收份额之前，所有活动产生的利润。

Net profit after tax is the final profit remaining after deducting corporation tax. This amount is available for distribution to shareholders as dividends or for reinvestment as retained profit.

税后净利润是扣除企业所得税后剩余的最终利润。这一金额可用于向股东分配股利或作为留存利润再投资。

Net Profit Before Tax = Gross Profit – Total Expenses

税前净利润 = 毛利 − 总费用

8. The Format of an Income Statement | 损益表的格式

An income statement follows a vertical format, starting with revenue and working down to net profit. The layout is designed to show profit at different stages. Below is a simplified example for a trading business:

损益表采用垂直格式，从收入开始，逐级向下计算至净利润。这种布局旨在显示不同阶段的利润。以下是一个贸易企业的简化示例：

Item	Amount ($)
Sales Revenue	200,000
Less: Cost of Sales	(120,000)
Gross Profit	80,000
Less: Operating Expenses	(45,000)
Net Profit Before Tax	35,000
Less: Tax	(7,000)
Net Profit After Tax	28,000

Notice how each deduction is clearly labelled, and the final profit figure is highlighted. In published accounts, more detail would be shown, but this core structure is always used.

请注意每一项扣除都清晰标注，最终利润数字突出显示。在公开报表中会展示更多细节，但这种核心结构始终被采用。

9. Interpreting Profit Margins | 解读利润率

Profit margins express profit as a percentage of sales revenue, making it easier to compare performance across different periods or with other businesses. The two most important margins are:

利润率将利润表示为销售收入的一个百分比，便于跨时期或与其他企业进行比较。两个最重要的利润率是：

Gross Profit Margin:

毛利率：

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

毛利率 = (毛利 ÷ 销售收入) × 100%

This ratio shows how much of each sales dollar remains after paying for the cost of goods sold. A rising gross margin suggests improving purchasing efficiency or stronger pricing power.

该比率显示了每1美元销售额在支付销售成本后还剩下多少。毛利率上升意味着采购效率提高或定价能力增强。

Net Profit Margin:

净利率：

Net Profit Margin = (Net Profit Before Tax ÷ Sales Revenue) × 100%

净利率 = (税前净利润 ÷ 销售收入) × 100%

The net margin reveals overall profitability after all operating and financing costs. If the net margin is thin, a small increase in expenses could wipe out profit entirely.

净利率揭示了扣除所有经营及融资成本后的整体盈利能力。如果净利率很薄，费用的小幅增加就可能完全侵蚀利润。

10. Uses of Income Statements for Stakeholders | 损益表对利益相关者的用途

Different groups use the income statement to make informed decisions:

不同的群体利用损益表做出明智决策：

Owners and shareholders – assess whether the business is generating acceptable returns and can sustain dividend payments.
所有者与股东 – 评估企业是否在产生可接受的回报，以及能否维持股利支付。
Managers – identify which products or departments are most profitable and where to cut costs.
管理者 – 确定哪些产品或部门最赚钱，以及应在何处削减成本。
Lenders and creditors – check if the business earns enough profit to cover interest and repay debts.
贷款人和债权人 – 核查企业是否赚取足够利润来支付利息和偿还债务。
Government – calculates tax liability based on declared profits.
政府 – 根据申报利润计算应缴税款。
Employees – gauge job security and the potential for wage increases or bonuses.
员工 – 判断工作稳定性以及加薪或奖金的潜力。

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

While the income statement is a powerful tool, it has several limitations that users must keep in mind.

虽然损益表是一个强大的工具，但它有若干局限性，使用者必须牢记。

Firstly, it includes non-cash items such as depreciation, meaning net profit does not equal cash generated. A company can show a healthy profit but still face a liquidity crisis if cash is tied up in inventory or receivables.

首先，它包含折旧等非现金项目，意味着净利润不等于产生的现金。一家公司可以显示健康的利润，但如果资金被存货或应收款占用，仍可能面临流动性危机。

Secondly, the figures rely on accounting estimates and management judgement. For example, the choice of depreciation method can significantly alter profit. Comparative analysis between firms can be distorted by different accounting policies.

其次，数据依赖于会计估计和管理层判断。例如，折旧方法的选择会显著影响利润。不同会计政策会扭曲企业间的比较分析。

Thirdly, the income statement only covers past performance. Investors need forward-looking information, which the historical income statement cannot provide. Finally, it ignores non-financial factors like customer satisfaction or employee turnover, which also affect future success.

第三，损益表只涵盖过去的业绩。投资者需要前瞻性信息，而基于历史的损益表无法提供。最后，它忽略了顾客满意度或员工流失等非财务因素，这些也会影响未来的成功。

12. Income Statement vs Statement of Financial Position | 损益表与财务状况表的对比

For IGCSE candidates, it is essential to distinguish the income statement from the statement of financial position (balance sheet). The income statement reports profit over a period; the balance sheet reports assets, liabilities and equity at a point in time. The net profit from the income statement flows into the equity section of the balance sheet as retained profit, linking the two statements.

对IGCSE考生来说，区分损益表与财务状况表（资产负债表）至关重要。损益表报告的是某一期间的利润；资产负债表报告的是某一时点的资产、负债与所有者权益。损益表中的净利润会转入资产负债表的权益部分成为留存利润，从而将两张报表联系起来。

The income statement is dynamic, like a video showing performance throughout the year, while the balance sheet is static, like a snapshot. Together with the cash flow statement, they form the complete set of financial statements used by stakeholders to evaluate a business.

损益表是动态的，就像一段展示全年业绩的视频；而资产负债表是静态的，如同一个快照。它们与现金流量表一起，构成了利益相关者评估企业所使用的完整财务报表。
