IGCSE Business Ch 23: Cash Flow & Working Capital

Cambridge IGCSE Business Studies

Cash Flow Forecasting and Working Capital

This chapter explains why cash matters, how cash moves into and out of a business, how managers forecast future cash balances, and why sufficient working capital is needed for day-to-day survival.

Topic 1: Cash, Cash Flow and Profit

Cash is needed for daily payments, while cash flow shows when money actually enters and leaves the business.

1. Why Cash Is Important

Cash is a liquid asset because it is immediately available for spending.

A business needs cash to pay employees, suppliers, rent, taxes and other day-to-day expenses.

Important: If a business runs out of cash, production may stop and the business could eventually be forced into liquidation.

Employees

Suppliers

Rent

Taxes

Daily expenses

2. Cash Flow

Cash flow is the movement of money into and out of a business over a period of time.

Cash inflows

Amounts of money received by a business.

Cash outflows

Amounts of money paid out by a business.

3. Cash Inflows

Cash inflows are amounts of money received by a business.

cash sales
payments from debtors
bank loans
sale of assets
money invested by owners or shareholders.

4. Cash Outflows

Cash outflows are amounts of money paid out by a business.

buying materials
wages and salaries
buying non-current assets
repaying loans
paying suppliers or creditors.

5. Cash Flow Cycle

The cash flow cycle shows the stages between a business paying cash for production and receiving cash from customers.

Cash paid out→Materials / wages→Production→Goods sold→Cash received

If customers buy on credit, the business must wait longer to receive its cash. The longer this cycle takes, the more cash and working capital the business may need.

Cash flow cycle from cash paid out to cash received from customers.

6. Cash Flow Is Not the Same as Profit

This is one of the most important points in the chapter. Profit is calculated from revenue and costs. Cash flow considers when money actually enters or leaves the business.

Key idea: A business may make a profit but still have very little cash.

Example: Goods sold = $40,000, but only half is paid immediately, so cash received = $20,000. Cash cost of goods = $15,000. Profit = $25,000, but net cash flow = $5,000 because some customers have not yet paid.

Comparison of profit and net cash flow using a business example.

7. Why a Profitable Business Can Run Out of Cash

A profitable business may still experience cash shortages.

Too much customer credit

Sales may be recorded, but cash is not received immediately.

Buying too many non-current assets

Large payments for machinery, vehicles or buildings reduce cash.

Expanding too quickly

Rapid expansion may require large inventories and other spending before cash from sales is received.

Overtrading can occur when a business expands too quickly and does not have enough cash to support the extra activity.

Topic 2: Cash Flow Forecasts and Calculations

Cash flow forecasts help managers predict future cash balances and identify shortages before they happen.

8. Cash Flow Forecast

A cash flow forecast estimates future cash inflows, cash outflows and cash balances.

It is usually prepared month by month.

9. Why Cash Flow Forecasts Are Important

Cash flow forecasts help managers make better decisions before cash problems become serious.

Predict cash shortages: Managers can identify when the bank balance may become negative.
Arrange finance in advance: A loan or overdraft can be arranged before the shortage occurs.
Plan business spending: Managers can see whether cash is available to buy assets or pay bills.
Support loan applications: Banks often want to see a cash flow forecast before lending money.

10. Cash Flow Forecast Calculations

Students need to know three important calculations.

Net Cash FlowCash Inflows − Cash Outflows

Closing BalanceOpening Balance + Net Cash Flow

Next Month's Opening BalanceThe closing balance of one month becomes the opening balance of the next month.

11. Example of a Cash Flow Forecast

Suppose cash inflows are $30,000, cash outflows are $25,000 and the opening balance is $4,000.

Net cash flow: $30,000 − $25,000 = $5,000.

Closing balance: $4,000 + $5,000 = $9,000.

Cash flow forecast calculations for net cash flow and closing balance.

12. Positive and Negative Net Cash Flow

Positive net cash flow

Cash inflows are greater than cash outflows, so the cash balance increases.

Negative net cash flow

Cash outflows are greater than cash inflows, so the cash balance decreases.

Important exam point: A negative net cash flow does not automatically mean the business has run out of cash. It depends on the opening balance.

Topic 3: Cash Flow Problems and Solutions

A business has a serious cash flow problem when it cannot meet its payments.

13. Cash Flow Problems

A cash flow problem occurs when a business does not have enough cash to meet its payments.

Possible consequences include:

inability to pay suppliers
inability to pay employees
production stopping
creditors taking action
business closure.

14. How to Improve a Short-Term Cash Flow Problem

Four important methods are:

1. Increase bank borrowing

Advantage: immediate cash inflow.

Disadvantages: interest must be paid and the loan must eventually be repaid.

2. Delay payments to suppliers

Advantage: reduces cash outflows temporarily.

Disadvantage: suppliers may refuse further supplies or withdraw discounts.

3. Ask debtors to pay more quickly

Advantage: cash inflows arrive sooner.

Disadvantage: customers may switch to competitors offering better credit terms.

4. Delay buying capital equipment

Advantage: reduces immediate cash outflow.

Disadvantage: outdated equipment may reduce efficiency in the long run.

15. Longer-Term Solutions

If cash problems continue, a business may consider:

attracting new investors
reducing costs
increasing efficiency
developing new products to increase sales.

Balanced answer: Each option can also have disadvantages or take time to work.

Topic 4: Working Capital and Exam Comparison

Working capital shows whether the business has enough short-term resources for daily operations.

16. Working Capital

Working capital is the capital available to pay the business's short-term, day-to-day expenses.

Working Capital = Current Assets − Current Liabilities

Working capital formula and forms of working capital.

17. Why Working Capital Is Important

A business needs enough working capital to:

pay everyday expenses
purchase inventories
continue production
take advantage of business opportunities.

Example: Sufficient working capital may allow a business to purchase materials offered at a discount.

18. Forms of Working Capital

Working capital may be tied up in cash, debtors and inventories.

Cash

Needed for everyday payments.

Debtors

Customers who owe the business money.

Inventories

Goods and materials held by the business.

Inventory point: Too much inventory may create high opportunity costs, while too little inventory may stop production.

19. Cash Flow Forecast vs Income Statement

Cash Flow Forecast	Income Statement
Shows cash entering and leaving.	Shows revenue, costs and profit.
Focuses on liquidity.	Focuses on profitability.
Concerned with timing of cash.	Revenue may include credit sales.
Can forecast future balances.	Shows profit or loss for a period.

Essential point: Profit does not guarantee good cash flow.

20. Key Formulas

Calculation	Formula
Net Cash Flow	Cash Inflows − Cash Outflows
Closing Balance	Opening Balance + Net Cash Flow
Working Capital	Current Assets − Current Liabilities

Key Definitions

Term	Meaning

Cash inflow	Money received by the business.
Cash outflow	Money paid out by the business.
Cash flow cycle	Stages between paying for production and receiving cash from sales.
