Completing a cash-flow forecast

A cash-flow forecast predicts the money coming into and going out of a business, month by month. Exam questions ask you to fill in missing figures and say what the forecast shows.

The layout

Cash inflows are money coming in: sales revenue (cash actually received), loans, owner's capital.
Cash outflows are money going out: stock, wages, rent, bills, loan repayments, equipment.
Net cash flow = total inflows − total outflows
Closing balance = opening balance + net cash flow
Each month's closing balance is the next month's opening balance.
Cash-flow forecast for Rise Bakery (fictional). Opening balance in April: £2000.

Reading the forecast

April's net cash flow is −£4200 because the business buys a new oven for £8000. The closing balance is −£2200: the business would run out of cash.
By June the closing balance is £900, so the problem is short-term. The owner should arrange an overdraft before April, or delay buying the oven, or pay for it in instalments.

Why cash matters

A business needs cash to pay suppliers, overheads and employees on time. If it cannot pay its debts it may become insolvent and fail, even if it is making a profit.
Cash is not the same as profit. Profit compares revenue with costs over a period; cash is the money actually in the bank. A profitable firm can run short of cash if customers pay late, it buys a lot of stock, or it spends on equipment.

Improving cash flow

Increase inflows: ask customers to pay sooner, offer discounts for prompt payment, sell unused assets, run promotions to boost sales.
Reduce or delay outflows: negotiate longer trade credit with suppliers, lease instead of buying equipment, cut unnecessary costs.
Cover a gap: an overdraft or short-term loan.
A forecast is only an estimate: sales and costs may turn out differently, so it should be updated regularly.
Worked example

In May, Rise Bakery's opening balance is −£2200. Total inflows are £8500 and total outflows are £7700. Find the net cash flow and the closing balance.

  1. Net cash flow = £8500 − £7700 = £800
  2. Closing balance = −£2200 + £800 = −£1400

Answer: Net cash flow £800; closing balance −£1400

Key idea

Net cash flow = total inflows − total outflows. Closing balance = opening balance + net cash flow, and it becomes next month's opening balance. A negative closing balance warns that the business needs finance or must change its plans.
