Use ABC information to make a supported recommendation
Turn driver-based cost information into a decision while testing the assumptions and considering non-financial factors.
Exam scope and assessment notes
Cambridge International AS & A Level Accounting 9706, 2026–2028 syllabus, Version 2. Topic 4.1 covers activity-based costing (ABC), cost drivers, overhead apportionment and allocation, unit cost and selling-price calculations, method comparisons, uses and limitations, 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 Topic 2.1–2.2 knowledge of fixed and variable costs, overhead absorption, cost-plus pricing and contribution. This A Level pathway compares those methods with activity-based costing.
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
What should a manager check before claiming that a cost pool will be saved by reducing activity?
What you will learn
- Use ABC figures as evidence for a business decision
- Evaluate alternatives and trade-offs
- Support a recommendation with numerical and non-financial reasons
Connect the cost analysis to a decision
A recommendation might address pricing, product design, batch size, process improvement or product mix. Identify which driver or pool is material and quantify its effect on total or unit cost.
Check whether the proposed action can change the activity cost, whether the relevant cost is avoidable and whether demand or capacity will respond. An allocated cost alone is not proof that discontinuing a product saves the amount assigned to it.
Balance financial and non-financial evidence
Consider non-financial factors such as quality, customer service, delivery reliability, staff skills, supplier relationships, capacity and strategic fit. A short-term cost reduction could harm product quality or future demand.
State the recommendation, supporting data and calculation, one counterargument or risk, and a condition to monitor. Use the ABC results to support business decisions alongside other evidence rather than claiming the allocation proves causation or market value.
Pause and explain
Which action could reduce set-up activity without assuming an immediate cash saving?
Worked example
ABC shows a product uses 40% of set-ups but produces 10% of output. State one possible action and one check before recommending it.
Show the worked solution
- The high set-up share may indicate small batches or frequent changeovers that drive overhead.
- Review whether larger batches, scheduling or design changes could reduce set-ups without creating excess inventory or slower customer response.
- Check demand, quality, inventory holding and whether set-up costs can actually be reduced before promising savings.
Answer Investigate batch planning or design changes, but test service, stock and actual avoidable-cost effects before acting.

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.
ABC assigns $24,000 of a $120,000 set-up pool to Product A. A redesign may cut A's set-ups by 25%. Estimate the allocation reduction and give one limitation.
Give me a hint
Apply the rate proportionally only as an allocation estimate.
Compare my reasoning
- Estimated reduction = 25% × $24,000 = $6,000.
- This would reduce A's allocated set-up overhead to $18,000 if other activity and rates remain unchanged.
- The pool's total spending may not fall by $6,000 unless resources or capacity costs can actually be reduced.
A's allocated amount could fall by $6,000 to $18,000; actual overhead savings require a change in resources or spending.
Look for these in your work
- Calculate the $6,000 allocated reduction.
- Find the new $18,000 allocation.
- Distinguish reallocation from cash saving.
ABC cost per unit is $550 for a low-volume product. A proposal would discontinue it and save $80,000 allocated overhead, but only $30,000 is avoidable. Lost contribution is $42,000. Calculate the net short-run profit effect before other effects.
Give me a hint
Compare avoidable savings with contribution lost; ignore overhead that remains.
Compare my reasoning
- Avoidable savings = $30,000.
- Lost contribution = $42,000.
- Net short-run effect = $30,000 − $42,000 = $12,000 decrease in profit; the remaining $50,000 allocation is not saved.
Discontinuing the product reduces short-run profit by $12,000 before other effects. Do not count the $50,000 overhead that remains as a saving.
Look for these in your work
- Use only the $30,000 avoidable cost.
- Subtract the $42,000 lost contribution.
- State a $12,000 profit decrease and exclude retained overhead.
A product has higher ABC cost but also protects a key customer relationship and keeps skilled staff employed. Frame a recommendation to the board.
Give me a hint
Quantify cost evidence and evaluate the customer and workforce consequences.
Compare my reasoning
- Confirm the driver allocations and estimate the product's contribution and avoidable costs, not just full allocated cost.
- Assess customer retention, related sales, staff skills, capacity alternatives and the cost of a transition.
- Recommend continuation, redesign or exit conditionally, with explicit risks and performance measures for review.
Use ABC to identify cost drivers, then compare avoidable costs and contribution with customer, workforce and capacity effects. A conditional redesign or review may be more justified than automatic closure.
Look for these in your work
- Validate the ABC cost evidence.
- Include customer and workforce effects.
- Make a conditional recommendation with review measures.
Common mistakes
- Recommending closure from allocated overhead alone
- Quoting a cost figure without explaining the driver
- Ignoring demand, quality or capacity consequences
