Use it to consolidate your understanding of Cambridge International AS & A Level Business (9609), Chapter 23.
现金是任何企业的生命线。如果没有周详的计划，即使是盈利的企业也可能耗尽现金并面临破产。这份复习题单回顾现金流预测的核心要点以及管理者用来维持流动性的策略，帮助你巩固对剑桥国际AS与A Level商务（9609）第23章的理解。
1. What is Cash Flow Forecasting? | 什么是现金流预测？
A cash flow forecast is a financial document that estimates the expected cash inflows (receipts) and cash outflows (payments) of a business over a specific future period, typically 6 to 12 months. It shows the timing and amount of cash moving in and out of the business, enabling managers to anticipate liquidity shortages.
现金流预测是一份财务文件，用来估算企业在特定未来时段（通常为6到12个月）内预期的现金流入（收入）和现金流出（支出）。它显示了现金进出企业的时点和金额，使管理者能够预见流动性短缺。
The forecast is based on assumptions about sales, costs, and payment patterns. It is not a guarantee but a planning tool. Even small errors in assumptions can lead to significant cash surpluses or deficits.
预测基于对销售、成本和付款模式的假设。它不是保证，而是一种规划工具。即便是假设中的微小误差，也可能导致显著的现金盈余或赤字。
2. The Purpose of Cash Flow Forecasts | 现金流预测的目的
The primary purpose is to identify potential cash shortfalls before they occur. By highlighting when cash outflows exceed inflows, a business can arrange finance in advance, delay payments, or accelerate receipts, thereby avoiding crisis management.
其主要目的是在现金短缺实际发生之前识别潜在缺口。通过凸显现金流出超过流入的时段，企业可以提前安排融资、推迟付款或加快收款，从而避免仓促的危机管理。
Forecasts also support strategic decision‑making. They help managers assess whether expansion plans are affordable, evaluate the impact of a major purchase, and convince lenders that the business can service additional debt.
预测还支持战略决策。它们帮助管理者评估扩张计划是否可负担，评价大额采购的影响，并说服贷款人企业有能力偿还额外债务。
For start‑ups, a cash flow forecast is a crucial part of the business plan. It demonstrates to investors and banks that the entrepreneur has thought carefully about liquidity requirements.
对于初创企业，现金预测是商业计划书的关键部分。它向投资者和银行展示企业家已仔细考量了流动性需求。
3. Structure of a Cash Flow Forecast | 现金预测表的结构
A typical cash flow forecast is laid out in columns for each month (or week) and rows for individual items. The main sections are:
典型的现金预测表按月份（或周）分列，按项目分行。主要部分包括：
- Cash inflows: cash sales, receipts from debtors, sale of assets, loans received, interest received.
- 现金流入：现金销售、应收账回款、资产出售、收到的贷款、利息收入。
- Cash outflows: cash purchases, payments to creditors, wages and salaries, rent, utilities, advertising, taxation, loan repayments, purchase of equipment.
- 现金流出：现金采购、应付账付款、工资薪金、租金、水电费、广告、税金、贷款偿还、设备购置。
- Net cash flow = Total inflows − Total outflows for each period.
- 净现金流 = 各期总流入 − 总流出。
- Opening balance: the cash held at the start of the period (previous month’s closing balance).
- 期初余额：期初持有的现金（上月的期末余额）。
- Closing balance = Opening balance + Net cash flow.
- 期末余额 = 期初余额 + 净现金流。
Each column tells a story: a negative closing balance signals an overdraft may be needed; a consistently high balance might suggest idle cash that could be invested.
每列都传递了一个信息：负的期末余额提示可能需要透支；持续的高余额则可能暗示有闲置现金可以用于投资。
4. Net Cash Flow and Closing Balance | 净现金流与期末余额
Understanding the two key figures is essential. Net cash flow does not measure profit; it simply records whether more cash came in than went out in a given month. The formula is:
理解这两个关键数字至关重要。净现金流并不衡量利润；它只记录某个月份现金流入是否大于流出。公式为：
Net Cash Flow = Total Cash Inflows − Total Cash Outflows
净现金流 = 现金总流入 − 现金总流出
The closing balance carries forward cash available to cover future obligations:
期末余额将可用现金带入未来，以覆盖未来的支付义务：
Closing Balance = Opening Balance + Net Cash Flow
期末余额 = 期初余额 + 净现金流
For example, if a business starts January with $5,000, receives $12,000 in inflows and pays out $10,000, the net cash flow is $2,000 and the closing balance is $7,000. This $7,000 becomes February’s opening balance.
例如，某企业1月初持有5000美元，收到流入12000美元，支付流出10000美元，净现金流为2000美元，期末余额为7000美元。这7000美元将成为2月的期初余额。
5. Cash vs Profit: Key Differences | 现金与利润：关键区别
A common misconception among candidates is to treat cash and profit as the same. In reality, a business can be highly profitable yet run out of cash. Key distinctions include:
考生常见的误解是将现金和利润视为同一回事。现实中，企业可能利润丰厚却耗尽现金。关键区别包括：
| Cash / 现金 | Profit / 利润 |
| Records actual money received and paid. | Records income earned and expenses incurred, regardless of payment timing. |
| 反映实际收到和支付的资金。 | 反映已获收入和已发生费用，不论支付时点。 |
| Immediate; affects liquidity. | Accrual basis; includes credit sales and depreciation. |
| 即时；影响流动性。 | 权责发生制；包含赊销和折旧。 |
| A negative cash flow can push a firm into bankruptcy. | A loss does not necessarily mean insolvency if cash reserves are sufficient. |
| 负现金流可能将企业推入破产。 | 亏损并不一定意味着无力偿债，如果现金储备充足。 |
Depreciation, for instance, reduces profit but is not a cash outflow. A large credit sale appears in profit immediately but may not result in cash for 60 days.
例如，折旧会减少利润，但不是现金流出。一笔大额赊销立即计入利润，但现金可能在60天后才到账。
6. Common Causes of Cash Flow Problems | 现金流问题的常见原因
Businesses face liquidity squeezes for a variety of reasons. Recognising these causes helps in mocks and exams where evaluation is required.
企业因各种原因面临流动性紧缩。识别这些原因有助于在模拟考和正式考试中进行评估。
- Overtrading: expanding output too quickly without sufficient working capital. Sales grow rapidly, but cash is tied up in inventory and receivables.
- 过度交易：在没有充足营运资金的情况下过快扩大产出。销售额迅速增长，但现金被困在存货和应收账款中。
- Seasonal demand: businesses with peak sales in short periods may experience severe cash shortages during off‑peak months whilst still incurring fixed costs.
- 季节性需求：销售集中在短期内高峰的企业，在淡季月份可能遭遇严重的现金短缺，而此时固定成本仍在发生。
- Poor credit control: allowing customers too much time to pay, or not chasing overdue accounts, delays inflows.
- 差劲的信用控制：给予客户过长的付款期限或未追讨逾期账款，延迟现金流入。
- Unexpected expenditure: equipment breakdowns, legal disputes, or sharp rises in raw material costs drain cash unexpectedly.
- 意外支出：设备故障、法律纠纷或原材料成本急剧上升，突然消耗现金。
- High drawings or dividends: the owner withdrawing too much cash or paying large dividends reduces funds available for operations.
- 高额的提款或股息：业主提款过多或支付大额股息，减少了可用于经营的资金。
7. Strategies to Improve Cash Flow | 改善现金流的策略
When a cash flow forecast reveals a looming shortfall, managers can adopt internal or external strategies. In exams, you should be able to recommend and justify appropriate measures.
当现金预测表显示逼近的缺口时，管理者可采取内部或外部策略。考试中，你需要能推荐并论证合适的措施。
- Reduce inventory levels: holding less stock frees up cash without harming sales if managed carefully. Just‑in‑time production can help.
- 降低库存水平：减少库存可释放现金，若管理得当不会损害销售。准时制生产可提供帮助。
- Improve credit control: shorten credit terms offered to customers, use prompt‑payment discounts, and chase overdue accounts vigorously.
- 改善信用控制：缩短给予客户的信用期限，使用早付折扣，积极追讨逾期账款。
- Extend payables period: negotiate longer credit terms with suppliers, delaying cash outflows without damaging relationships.
- 延长应付账期限：与供应商协商更长的信用期，推迟现金流出而不损害关系。
- Lease rather than buy: leasing equipment spreads payments over time, avoiding a large upfront cash outflow.
- 租赁而非购买：租赁设备将付款分期，避免大额的预付现金流出。
- Arrange an overdraft or short‑term loan: provides an immediate buffer, but incurs interest costs and bank scrutiny.
- 申请透支或短期贷款：提供即时缓冲，但会产生利息成本和银行审查。
- Debt factoring: selling trade receivables to a specialist firm at a discount generates quick cash, although profit margin is sacrificed.
- 债务保理：将应收账款折价出售给专业公司，快速产生现金，但会牺牲利润空间。
- Sale of unused assets: disposing of idle machinery or property can bring in a lump sum of cash.
- 出售闲置资产：处置闲置机械或房产可带来一次性现金。
8. Worked Example: Constructing a Forecast | 实做范例：编制预测表
Zara’s Crafts has the following expectations for the first three months of the year. Cash inflows: cash sales $8,000 in January, $6,000 in February and $9,000 in March; debtors pay $2,000 in January and $3,000 in March. Cash outflows: material purchases $3,500 each month; wages $2,000 per month; rent $1,500 per month; advertising $800 in January and $300 in March. The opening balance on 1 January is $1,200.
Zara’s Crafts 对年初三个月的预期如下。现金流入：1月现金销售8000美元，2月6000美元，3月9000美元；应收款在1月支付2000美元，3月支付3000美元。现金流出：材料采购每月3500美元；工资每月2000美元；租金每月1500美元；广告1月800美元，3月300美元。1月1日期初余额为1200美元。
| Item / 项目 | Jan ($) | Feb ($) | Mar ($) |
|---|---|---|---|
| Inflows / 流入 | |||
| Cash sales | 8,000 | 6,000 | 9,000 |
| Receipts from debtors | 2,000 | 0 | 3,000 |
| Total Inflows / 流入合计 | 10,000 | 6,000 | 12,000 |
| Outflows / 流出 | |||
| Material purchases | 3,500 | 3,500 | 3,500 |
| Wages | 2,000 | 2,000 | 2,000 |
| Rent | 1,500 | 1,500 | 1,500 |
| Advertising | 800 | 0 | 300 |
| Total Outflows / 流出合计 | 7,800 | 7,000 | 7,300 |
| Net Cash Flow / 净现金流 | 2,200 | (1,000) | 4,700 |
| Opening Balance / 期初余额 | 1,200 | 3,400 | 2,400 |
| Closing Balance / 期末余额 | 3,400 | 2,400 | 7,100 |
The February net cash flow is negative $(1,000), pulling the closing balance down to $2,400. While the business remains liquid, the forecast shows a dip that managers should monitor. By March, stronger inflows restore a healthy closing balance.
2月净现金流为负1000美元，将期末余额拉低至2400美元。尽管企业仍保持流动性，但预测表显示了一次下滑，管理者应予以关注。到3月，更强的流入恢复了健康的期末余额。
In an exam, you could be asked to calculate missing figures or comment on what the forecast reveals about liquidity. Practice by adjusting the assumptions: what if material costs rose 10% in February?
在考试中，你可能需要计算缺失的数字或评论预测表所揭示的流动性状况。可通过调整假设来练习：如果2月材料成本上涨10%会怎样？
9. Limitations of Cash Flow Forecasts | 现金流预测的局限性
While invaluable, cash flow forecasts rest on estimates. Their usefulness depends on the accuracy of predictions regarding sales volumes, payment timing, and costs. Common limitations include:
虽然宝贵，但现金流预测建立在估计之上。其有用性取决于对销量、付款时点和成本的预测准确性。常见局限包括：
- Inaccurate assumptions: overly optimistic sales forecasts or underestimating costs can paint a misleadingly rosy picture.
- 不准确的假设：过于乐观的销售预测或低估成本会描绘出虚假的美好图
