Cash Flow Forecasting and Working Capital (Cambridge IGCSE 0450)
Profitable businesses can still fail if they run out of cash. Cambridge IGCSE 0450 requires you to interpret and complete cash-flow forecasts, calculate working capital and suggest ways to solve cash-flow problems.
Cash is not profit
Cash flow is the movement of money into and out of a business, and it is not the same as profit. A firm can sell goods profitably on credit but receive no cash for sixty days, while wages, rent and suppliers must be paid now. That timing gap is why profitable businesses can become insolvent.
Cash inflows include cash sales, payments received from trade receivables, loans received, new capital from owners and the sale of unwanted assets. Cash outflows include payments for materials, wages, rent, utilities, loan repayments, tax payments and the purchase of equipment. A new business is especially vulnerable: it must pay for premises, equipment and inventory months before regular sales revenue arrives, which is why lenders always ask to see a cash-flow forecast in the business plan.
The cash-flow forecast: worked example
A cash-flow forecast estimates monthly inflows and outflows to reveal shortages before they happen. Each month follows the same logic: net cash flow = inflows − outflows, and closing balance = opening balance + net cash flow.
| $ | January | February |
|---|---|---|
| Opening balance | 5,000 | 3,000 |
| Cash inflows | 22,000 | 26,000 |
| Cash outflows | 24,000 | 23,000 |
| Net cash flow | (2,000) | 3,000 |
| Closing balance | 3,000 | 6,000 |
In January outflows exceed inflows, so net cash flow is −2,000 and the balance falls from 5,000 to 3,000. February's closing balance becomes 3,000 + 3,000 = 6,000. If a forecast shows a negative closing balance, the business must arrange finance, such as an overdraft, in advance.
Working capital and solving cash-flow problems
Working capital is the finance available for day-to-day running costs, calculated as current assets minus current liabilities. A business with current assets of $30,000 and current liabilities of $20,000 has working capital of $10,000. Too little working capital risks unpaid bills; too much means cash sits idle instead of earning a return.
Ways to improve a cash-flow problem include:
- Arrange an overdraft or short-term loan to cover a temporary gap.
- Ask suppliers for longer credit terms, delaying outflows.
- Chase trade receivables or offer small discounts for early payment, speeding up inflows.
- Cut inventory levels so less cash is tied up in stock.
- Delay buying equipment, or lease it instead of buying.
- Inject new capital from the owners.
Each fix has a cost: overdraft interest, lost bulk discounts or annoyed suppliers, so the best answer matches the solution to the cause.

Practice questions
Identify two examples of cash outflows for a retail business. [2 marks]
Model answer guidance: Acceptable answers include payments to suppliers for goods, wages, rent, electricity bills, tax payments and loan repayments. Any two earn the marks. Keep each example short.
A business has an opening balance of $4,000, forecast inflows of $18,000 and forecast outflows of $21,000 for March. Calculate the net cash flow and the closing balance. [4 marks]
Model answer guidance: Net cash flow is inflows minus outflows: 18,000 − 21,000 = −3,000, a net outflow of $3,000. The closing balance is the opening balance plus net cash flow: 4,000 − 3,000 = $1,000. The business stays in positive cash but the cushion is now small, so April needs watching.
Explain two reasons why a profitable business might still experience cash-flow problems. [6 marks]
Model answer guidance: If the business sells mainly on credit, profit is recorded at the sale but cash arrives weeks later, while wages and suppliers must be paid immediately. Also, buying expensive equipment or building up inventory drains cash without appearing as an expense that reduces profit straight away. In both cases the timing of cash movements, not the level of profit, causes the shortage.
A furniture maker's forecast shows a negative closing balance in two months' time. Consider two possible actions and justify which one it should take. [8 marks]
Model answer guidance: It could arrange an overdraft, which is quick and flexible and covers the gap, but interest charges add cost and the bank can demand repayment at short notice. Alternatively it could chase trade receivables and offer a small discount for early payment, which brings inflows forward without new debt, though the discount slightly reduces revenue. Because the problem has been spotted early, chasing receivables first is the better choice, keeping the overdraft as a back-up if customers still pay late.
Do you think holding high levels of working capital is always good for a business? Justify your answer. [12 marks]
Model answer guidance: High working capital means current assets comfortably exceed current liabilities, so bills, wages and suppliers can always be paid on time and the business can survive unexpected shocks. However, working capital held as large inventories or a big idle bank balance earns little return: cash tied up in stock could instead fund marketing or equipment, and excessive receivables suggest weak credit control. A justified conclusion could state that a business needs sufficient, not maximum, working capital, and the right level depends on how quickly inventory sells and how reliably customers pay. Applying this to the business in the question earns the top band.
Examiner tips
- Learn the two forecast formulas until automatic: net cash flow = inflows − outflows, and closing balance = opening balance + net cash flow; one month's closing balance is the next month's opening balance.
- Never write that cash and profit are the same: examiners regularly test the difference, so mention credit sales timing in your explanation.
- When suggesting solutions to cash-flow problems, add the drawback of each solution, such as overdraft interest, because that analysis lifts you into the higher bands.
