Who this is for: Cambridge IGCSE Business Studies (0450) students who want cash flow forecasting and working capital — net cash flow, opening and closing balances and managing liquidity — to become a reliable source of marks instead of tables they complete with arithmetic errors.
What query it owns: how to understand and revise cash flow forecasting and working capital in Cambridge IGCSE Business Studies.
Why this is safe: this page owns the cash-flow-forecasting revision-guide angle, while Tutopiya’s Cash Flow Forecasting And Working Capital subtopic page owns the learning resource and the free Cash Flow Forecasting And Working Capital quiz owns the practice.

Cash flow forecasting and working capital show whether a business can pay its bills on time. Cambridge IGCSE Business Studies (0450) expects you to complete cash flow forecasts, calculate net cash flow and closing balances and explain why profit and cash are not the same. This guide links each line of the forecast to the command words examiners use, so you can answer calculate, explain and interpret questions with confidence.

Key takeaways

• Cash flow tracks money in and out of the business; profit is revenue minus costs — they differ because of timing.
• Net cash flow = cash inflows − cash outflows for a period.
• Closing balance = opening balance + net cash flow.
• A negative net cash flow means more cash left than entered — the business may need an overdraft.
• Working capital = current assets − current liabilities; it funds day-to-day operations.

What is cash flow forecasting and working capital in Cambridge IGCSE Business Studies?

Cash flow forecasting predicts cash inflows and outflows over future months so a business can plan for shortages. Working capital is the money available for daily expenses. A business can be profitable but run out of cash if customers pay late or large bills fall due before sales revenue arrives. In Cambridge IGCSE Business Studies (0450), you must complete forecast tables and explain how to improve cash flow.

Structure of a cash flow forecast

Line	What it shows	How to calculate
Opening balance	Cash at the start of the month	Given or previous month’s closing balance
Cash inflows	Money received (cash sales, customer payments)	Add all inflows
Cash outflows	Money paid (wages, rent, suppliers)	Add all outflows
Net cash flow	Surplus or deficit for the month	Inflows − outflows
Closing balance	Cash at the end of the month	Opening balance + net cash flow

Profit vs cash flow — why they differ

Feature	Profit	Cash flow
Measures	Revenue minus costs (accrual)	Actual money in and out
Includes credit sales?	Yes — counted when sale made	No — only when cash received
Includes depreciation?	Yes — reduces profit	No — not a cash payment
Can be positive while cash is negative?	Yes	A profitable firm can still face a cash shortage

How to complete a cash flow forecast — step by step

1. Start with the opening balance for month 1 (given in the question).
2. Add all cash inflows for the month (cash sales, money from debtors).
3. Add all cash outflows (wages, rent, purchases, loan repayments).
4. Calculate net cash flow = total inflows − total outflows.
5. Calculate closing balance = opening balance + net cash flow.
6. Carry closing balance forward as next month’s opening balance.
7. Test yourself with the free Cash Flow Forecasting And Working Capital quiz.

Cash flow in past-paper wording: command words that matter

Command word / phrase	What the question wants	Typical cash flow stem
Calculate	Show working for a value	”Calculate the closing balance for March.”
Complete	Fill in missing figures in a table	”Complete the cash flow forecast for April.”
Explain	Developed reasoning	”Explain why a profitable business might have cash flow problems.”
Suggest … justify	Recommend an action + reasons	”Suggest how the business could improve its cash flow. Justify your answer.”
Identify	Pick from the forecast	”Identify the month with the lowest closing balance.”
Define	Precise meaning	”Define working capital.”

Worked exam-style stems (how to answer the wording)

1. “Opening balance is $5 000. Cash inflows are $12 000 and cash outflows are $14 000. Calculate the closing balance.” Net cash flow = $12 000 − $14 000 = −$2 000. Closing balance = $5 000 + (−$2 000) = $3 000. Mark-scheme reward: net cash flow shown + correct closing balance.
2. “Explain why a profitable business might have cash flow problems.” Customers buy on credit so revenue is recorded but cash is not received yet; large bills such as rent must be paid before customer payments arrive. Reward: timing difference explained with examples.
3. “Suggest how the business could improve its cash flow. Justify your answer.” Offer discounts for early payment — encourages customers to pay sooner, increasing cash inflows and reducing the risk of a negative closing balance. Reward: method named + two developed justifications.

How cash flow connects to Financial Information and Decisions

Cash flow forecasting follows Business Finance Needs And Sources because a cash shortage may require an overdraft or loan, and contrasts with Income Statements which show profit, not cash. The Cambridge IGCSE Business Studies resource hub links every Financial Information subtopic.

Common mistakes students make

• Confusing profit with cash flow — they measure different things.
• Forgetting to add opening balance to net cash flow for closing balance.
• Treating credit sales as cash inflows in the month of sale — cash arrives later.
• Not carrying the closing balance forward as the next opening balance.
• Subtracting inflows from outflows instead of outflows from inflows.

Frequently asked questions

What is net cash flow? The difference between total cash inflows and total cash outflows for a period. Positive net cash flow means more money came in than went out.

Why can a business be profitable but run out of cash? Profit includes credit sales and excludes timing of payments. Cash may leave the business for wages and rent before customer payments arrive.

How do you calculate closing balance? Closing balance = opening balance + net cash flow. If net cash flow is negative, subtract it from the opening balance.
