Prepare a production budget
Convert expected sales into production units by allowing for opening and desired closing finished goods inventory.
Cambridge International AS & A Level Accounting 9706, 2026–2028 syllabus, Version 2. Topic 4.3 covers budgetary control, linked master-budget schedules, spreadsheets, limiting factors, flexible budgets, reconciliations, behavioural effects and supported decisions. Practice is self-checked, not an official Cambridge grade. Full timed Papers 1–4 and human subject-teacher review remain outstanding.
Before you begin
- Use AS Topics 2.1–2.2 for cost behaviour, contribution and budgeting foundations. For each schedule, label the period, units, price, inventory policy, timing assumptions and opening balance before calculating.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
If opening inventory is 100 and closing inventory is 120, has inventory increased or decreased?
What you will learn
- Calculate required production units
- Explain inventory-policy effects
- Link production to resource budgets
Adjust sales for finished inventory
Production units = budgeted sales units + desired closing finished goods inventory − opening finished goods inventory. Opening inventory is already available to meet sales; the desired closing balance is additional stock the business plans to hold.
Use units for the same product and period. If production is negative or unusually high, check sales, inventory policy and capacity assumptions rather than accepting an implausible result.
Production drives resource needs
Budgeted production units feed material, labour and production-overhead budgets. They may differ from sales units because inventory changes during the period.
Holding more stock may protect service against demand or supply uncertainty, but it uses cash and storage and can create damage or obsolescence. Production targets should reflect demand and inventory policy, not the wish to create a favourable overhead-absorption result.
Pause and explain
Sales are 900; opening stock is 80; desired closing stock is 110. What production is required?
Worked example
Sales are budgeted at 4,800 units. Opening inventory is 600 units and desired closing inventory is 700 units. Find production units.
Show the worked solution
- Start with sales: 4,800.
- Add desired closing stock and subtract opening stock: 4,800 + 700 − 600.
- Check that production plus opening stock covers sales and closing stock.
Answer Production = 4,900 units; 4,900 + 600 = 4,800 + 700.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
A toy maker forecasts sales of 6,500 units, starts with 900 in stock and wants 750 at period end. Find production.
Give me a hint
Use sales plus closing stock less opening stock.
Compare my reasoning
- 6,500 + 750 − 900.
- 6,500 + 750 = 7,250.
- 7,250 − 900 = 6,350 units.
Production budget = 6,350 units.
Look for these in your work
- Sales units used
- Closing inventory added
- Opening inventory subtracted
Quarter sales are 12,000 units; opening inventory is 1,400; target closing inventory is 1,100. Calculate production and explain why it is below sales.
Give me a hint
Calculate the inventory decrease as well as production.
Compare my reasoning
- Production = 12,000 + 1,100 − 1,400 = 11,700.
- Inventory falls by 300 units.
- Opening stock helps meet sales, so production is 300 units below sales.
Production is 11,700 units, 300 below sales because inventory is planned to fall by 300.
Look for these in your work
- Units calculated
- Inventory movement identified
- Sales/production difference explained
A retailer proposes doubling closing stock to avoid future shortages. What should its budget review include?
Give me a hint
Balance service risk against cash, storage, waste and supply uncertainty.
Compare my reasoning
- Quantify extra purchases or production needed to reach the higher closing inventory.
- Calculate cash tied up and storage or insurance costs.
- Compare supplier reliability and expected demand with the service benefit of extra stock.
Assess the service benefit against cash, storage and obsolescence costs and the actual supply risk before changing the stock target.
Look for these in your work
- Extra units quantified
- Holding costs considered
- Demand and supply evidence weighed
Common mistakes
- Subtracting closing stock
- Adding opening inventory
- Equating production units with sales units when inventory changes
What can you explain now?
Which formula gives production units?
Compare with the explanation
Sales + desired closing inventory − opening inventory
Production must cover sales and leave the planned closing stock after using opening stock.
