Cash Flow & Cash-Flow Forecasts (Years 8–11) — Business Studies

Cash flow tracks money in and out over time; a forecast helps spot and solve shortages before they hit.

Cash flow is the movement of money into and out of a business over time. A cash-flow forecast predicts these movements month by month so problems can be seen in advance.

Why this matters Most businesses that fail do so because they run out of cash, not because they are unprofitable. A forecast is an early warning system.

Cash is not profit

Profit is revenue minus total costs measured over a period, such as a year. Cash is the actual money available in the business right now. A firm can sell goods on credit — recording a profit on those sales — yet hold very little cash until its customers actually pay. In the same way, buying a large amount of stock uses up cash today even though it has not yet been sold. That gap between profit and cash is exactly why the two must be planned and managed separately.

Reading a cash-flow forecast

Each month we record cash in, cash out, and the balances. The rules are simple:

Net cash flow = cash in − cash out.
Closing balance = opening balance + net cash flow.
This month's closing balance becomes next month's opening balance.

(£)	Month 1	Month 2
Opening balance	1,000	1,500
Cash in	4,000	4,500
Cash out	3,500	5,000
Net cash flow	500	−500
Closing balance	1,500	1,000

In Month 1 above, more cash came in than went out, so the balance rose from £1,000 to £1,500. In Month 2 cash out was higher than cash in, giving a negative net cash flow and pulling the balance back down to £1,000. Reading a forecast in this way, month by month, lets an owner see exactly when a shortage is likely to appear.

When cash in exceeds cash out, the closing balance rises (Month 1); when cash out exceeds cash in, it falls (Month 2) — even though the business could be profitable both months.

Solving cash-flow problems

If a forecast shows a shortage, a business can act early rather than waiting for a crisis. Ways to improve cash flow include:

Ask customers to pay sooner, or reduce the credit given to them.
Ask suppliers for more time to pay (trade credit), so cash leaves the business later.
Delay or spread out large purchases of equipment.
Arrange a short-term overdraft to cover a temporary gap.
Cut or delay non-essential spending until cash recovers.

A forecast does not stop problems by itself — its value is that it gives the owner time to act before the cash runs out.

Put these steps in order for reading one month of a cash-flow forecast:

Start with the opening balance (last month's closing balance)
Add up all cash in for the month
Add up all cash out for the month
Calculate net cash flow (cash in − cash out)
Calculate the closing balance (opening balance + net cash flow)

Common exam mistake: calculating "cash in − cash out" and writing that figure down as the closing balance. That calculation only gives the net cash flow — you must then add it to the opening balance to get the actual closing balance.

Exam technique: when completing a cash-flow forecast table, always work left to right and top to bottom in this order: opening balance → cash in → cash out → net cash flow → closing balance — and remember each closing balance becomes next month's opening balance.
