What this dot point is asking

SEAB wants you to prepare functional budgets, especially the cash budget, and to explain why businesses budget at all. Budgeting is forward-looking planning, in contrast to the historical financial statements. The central insight is that the budgets form a linked chain, sales drive production, production drives purchases, and all of them drive cash, and the cash budget is pivotal because a plan that runs out of cash cannot be executed however profitable it looks.

The answer

The chain of functional budgets

Budgets are prepared in a logical sequence, each feeding the next:

Budget	Built from	Formula logic
Sales budget	Demand forecast	Units and revenue expected
Production budget	Sales budget	Sales + closing inventory - opening inventory
Materials purchases budget	Production budget	Usage + closing material stock - opening material stock
Labour budget	Production budget	Hours needed times wage rate
Cash budget	All of the above	Receipts less payments, rolled forward

The recurring pattern is "required amount adjusted for the desired change in stock", which appears in both the production and purchases budgets.

The cash budget

The cash budget lists expected receipts and payments month by month and rolls the closing balance into the next month's opening balance:

\text{Closing balance} = \text{opening balance} + \text{receipts} - \text{payments}

Crucially, it is built on cash flows, not profit: it timing-adjusts for when customers pay and suppliers are paid, includes capital spending and loan flows, and excludes non-cash items like depreciation. It reveals months of shortfall in advance, so finance (such as an overdraft) can be arranged before a crisis.

Why budget

Budgeting serves several purposes, often summarised as planning, control, coordination, communication and motivation:

Planning forces managers to think ahead and set targets.
Control comes from comparing actual results with the budget (variance analysis).
Coordination aligns the functional areas so production matches sales.
Communication and motivation give staff clear, agreed targets.

Worked example

A firm forecasts sales of $\$ 80,000 $(month 1) and$ \ $90\,000$ (month 2). Customers pay $40\%$ in the month of sale and $60\%$ the following month. Month 1 also collects $\$ 30,000 $from prior sales. Payments are$ \ $60\,000$ (month 1) and $\$ 75,000 $(month 2). Opening cash is$ \ $5\,000$ . Prepare the two-month cash budget.

Step 1: Calculate receipts

Month 1: $40\% \times 80\,000 = \$ 32,000 $from this month, plus$ \ $30\,000$ from prior sales $= \$ 62,000 $. Month 2:$ 60% \times 80,000 = \ $48\,000$ (month 1's credit) plus $40\% \times 90\,000 = \$ 36,000= \ $84\,000$ .

Step 2: Month 1 closing balance

5\,000 + 62\,000 - 60\,000 = \$7\,000

Step 3: Month 2 closing balance

Opening $= \$ 7,000 $(rolled forward).$ 7,000 + 84,000 - 75,000 = \ $16\,000$ .

Step 4: Interpret

Cash budget	Month 1	Month 2
Opening balance	5,000	7,000
Receipts	62,000	84,000
Payments	(60,000)	(75,000)
Closing balance	7,000	16,000

The firm stays in surplus throughout. The key skill is timing the receipts correctly across the credit period, not simply using the sales figures, which is what separates a cash budget from a profit forecast.

Examples in context

Example 1. Spotting a seasonal squeeze. A toy retailer's sales peak before year-end but it must buy stock months earlier. Its cash budget shows heavy payments in the months before the sales receipts arrive, predicting a cash shortfall in the autumn. Forewarned, it arranges a seasonal overdraft. The cash budget converts a profitable seasonal plan into a workable one by revealing the timing gap between paying for stock and collecting cash.

Example 2. Coordinating production with sales. A manufacturer's sales budget plans a launch that doubles demand mid-year. The production budget, built from it, schedules a stock build-up beforehand (production exceeding sales), and the purchases budget orders extra materials earlier still. The linked budgets coordinate the whole supply chain around the sales plan, illustrating the coordination benefit of budgeting.

Try this

Q1. Sales are $4\,000$ units, desired closing inventory $700$ , opening inventory $500$ . Find the production budget. [2 marks]

Cue. $4\,000 + 700 - 500 = 4\,200$ units.

Q2. Opening cash is $\$ 10,000 $, receipts$ \ $45\,000$ , payments $\$ 52,000$. Find the closing balance and comment. [2 marks]

Cue. $10\,000 + 45\,000 - 52\,000 = \$ 3,000$; still positive but payments exceeded receipts, drawing the balance down.

Q3. Explain why depreciation does not appear in a cash budget. [2 marks]

Cue. A cash budget records only actual cash movements; depreciation is a non-cash accounting charge, so it is excluded.

Original8 marksA business expects sales receipts of

\

50\,000

,

60\,000

in three months, and payments of

\

\

8\,000$. Prepare the cash budget for the three months and identify any month needing finance.

The cash budget rolls the closing balance of one month into the opening balance of the next.

Cash budget	Month 1	Month 2	Month 3
Opening balance	8,000	18,000	8,000
Add receipts	50,000	60,000	55,000
Less payments	(40,000)	(70,000)	(48,000)
Closing balance	18,000	8,000	15,000

Month 1: $8\,000 + 50\,000 - 40\,000 = \$ 18,000 $. Month 2:$ 18,000 + 60,000 - 70,000 = \ $8\,000$ . Month 3: $8\,000 + 55\,000 - 48\,000 = \$ 15,000$.

No month shows a negative balance, so no overdraft is strictly required, though month 2's payments exceed its receipts by $\$ 10,000$, drawing the balance down. If a minimum balance were required, finance might be arranged before month 2.

Markers reward rolling the closing balance forward, correct monthly closing figures of $\$ 18,000 $,$ \ $8\,000$ and $\$ 15,000$, and a comment on the tightest month.

Original6 marksA company expects to sell

5\,000

units in a month. It wants closing inventory of

800

units and has opening inventory of

500

units. (a) Calculate the production budget in units. (b) If each unit needs

2\,\text{kg}

of material, calculate the materials purchases budget in kg, given desired closing material stock of

1\,000\,\text{kg}

and opening material stock of

600\,\text{kg}

Show worked answer →

(a) Production budget: units to produce $=$ sales $+$ closing inventory $-$ opening inventory $= 5\,000 + 800 - 500 = 5\,300 \text{ units}$ .

(b) Materials usage: $5\,300 \text{ units} \times 2\,\text{kg} = 10\,600\,\text{kg}$ .

Materials purchases budget: usage $+$ closing material stock $-$ opening material stock $= 10\,600 + 1\,000 - 600 = 11\,000\,\text{kg}$ .

The logic is the same at each stage: required output (or usage) adjusted for the desired change in stock. Production exceeds sales because inventory is being built up; purchases exceed usage for the same reason.

Markers reward the production budget of $5\,300$ units, materials usage of $10\,600\,\text{kg}$ , and purchases of $11\,000\,\text{kg}$ , each adjusting for the stock change.
