Timing of money in and out
A cash flow forecast predicts cash movements over future months. A profitable business can still fail if cash runs out — timing matters.
Your salary might be $3 000/month but rent is due on the 1st while pay arrives on the 28th. Without a forecast you could look 'rich' on paper yet miss rent. Businesses face the same timing gaps with suppliers, wages, and customer payments.

Comparison of Cash Flow and Profit
| Feature | Cash Flow | Profit |
|---|---|---|
| Definition | The net movement of cash into and out of a business over a period. | The financial gain remaining after subtracting total costs from total revenue. |
| Focus | Liquidity and solvency; the ability to pay bills. | Performance and efficiency; the ability to generate a surplus. |
| Timing | Records transactions when cash is actually received or paid. | Records revenue when earned and expenses when incurred (accruals concept). |
| Key Exclusions | Excludes non-cash items like depreciation and credit sales (until paid). | Excludes capital transactions like loan receipts or purchase of assets. |
| Financial Statement | Cash Flow Statement / Cash Flow Forecast | Income Statement (Profit and Loss Account) |

The Purpose and Structure of a Cash Flow Forecast
A cash flow forecast is a forward-looking financial document that estimates the timing and amount of cash moving into and out of a business over a specific period, typically on a monthly basis. Its primary purpose is to help a business anticipate and manage its cash position, ensuring it has sufficient liquidity to meet its short-term obligations. By predicting potential cash surpluses or deficits (shortfalls), managers can make proactive decisions. For example, a forecast might highlight the need to arrange an overdraft to cover a temporary shortfall or plan for the investment of a future surplus. It is a vital tool for financial planning, control, and securing external finance from banks or investors, who will want to see evidence of sound financial management.
Predicts future cash inflows (receipts) and outflows (payments).

A key management tool for decision-making and control.
Essential for supporting applications for finance, such as bank loans.
Focuses solely on the movement of cash, not profit.
Key Components: Inflows, Outflows and Balances
A standard cash flow forecast is structured into three main sections. First, 'Cash Inflows' (or receipts) list all sources of cash entering the business, such as cash sales, payments from debtors, loans received, and capital investment. Second, 'Cash Outflows' (or payments) detail all cash leaving the business, including payments for materials, wages, rent, marketing, and asset purchases. It is crucial to remember that only actual cash movements are recorded; non-cash items like depreciation are excluded. Finally, the 'Net Cash Flow' and 'Balances' section calculates the overall cash position. This structure allows a business to clearly see where its cash is coming from and where it is being spent each month, providing a clear picture of its liquidity.
Cash Inflows: Cash from sales, debtors, loans, owner's capital.
Cash Outflows: Payments for stock, wages, rent, utilities, taxes.
Credit transactions are recorded when the cash is received/paid, not at the point of sale/purchase.
Non-cash items like depreciation and profit on disposal are excluded.
In exam questions, be careful to distinguish between sales revenue and cash received from sales. If a business makes credit sales, the cash inflow will be delayed and should be recorded in the month the payment is actually received from the debtor, not the month the sale was made.
Calculating Net Cash Flow and Closing Balance
The calculation within a cash flow forecast follows a logical, sequential process. For each period, you first sum all individual cash inflows to get 'Total Inflows' and all cash outflows to get 'Total Outflows'. The 'Net Cash Flow' for the period is then calculated by subtracting total outflows from total inflows. A positive result indicates a surplus, while a negative result signifies a deficit. To find the 'Closing Balance', you add the net cash flow to the 'Opening Balance' (the cash held at the start of the period). Crucially, the closing balance of one period becomes the opening balance for the very next period, linking the months together in a continuous financial narrative. This rolling calculation is fundamental to forecasting the cash position over time.
Net Cash Flow = Total Cash Inflows - Total Cash Outflows.
Closing Balance = Opening Balance + Net Cash Flow.
The closing balance for one month is always the opening balance for the following month.
A negative closing balance is shown in brackets, e.g., (£500).
When asked to complete a cash flow forecast, always show your workings for Total Inflows, Total Outflows, and Net Cash Flow. Even if your final closing balance is incorrect, you can gain marks for correct calculations of the intermediate steps. Pay close attention to the opening balance provided.
Managing Cash Flow Shortfalls
A forecast that predicts a negative closing balance, or cash shortfall, is not a failure but an opportunity for proactive management. A business has several options to address a temporary liquidity problem. Short-term solutions include arranging a bank overdraft, which provides a flexible but often expensive source of finance. A business could also try to improve inflows by offering discounts for early payment to debtors or running a destocking sale. To reduce outflows, a business might delay payments to creditors (suppliers), though this can damage relationships, or postpone non-essential capital expenditure. The chosen solution must be appropriate for the scale and duration of the shortfall; a long-term problem cannot be solved with a short-term fix like an overdraft.
Short-term finance: Arrange a bank overdraft or a short-term loan.
Improve inflows: Chase debtors, offer early payment discounts, reduce credit periods for customers.
Reduce outflows: Delay payments to suppliers, cut discretionary spending, postpone capital projects.
The suitability of each method depends on the cause, size, and duration of the cash shortfall.
Building the forecast
Net cash flow = Cash inflows − Cash outflows
Closing balance = Opening balance + Net cash flow
Next month opening balance = Previous month closing balance
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
Opening balance January January: inflows $18 000, outflows $20 000. February: inflows $22 000, outflows $19 000.
Calculate net cash flow and closing balance for each month.

January Net cash flow = 18 000 − 20 000 = **− Closing balance = 5 000 + (−2 000) = **
A firm forecasts negative closing balance of $4 000 in March. Suggest three actions to address this.

1. Arrange overdraft — short-term external finance to cover the gap (link 5.2.2).
