What a finished ACC-650 Topic 8 relevant cost decision looks like
The finished example builds each decision from only what changes. Sunk costs are excluded and named as excluded, since the discipline is visible only when the paper says what it left out. Unavoidable fixed costs are treated the same way, which is what makes a keep or drop decision counterintuitive: dropping a product with a positive contribution makes the firm worse off even though the product statement shows a loss, because the allocated fixed costs continue. Opportunity cost is included even though no invoice exists for it, particularly the alternative use of capacity in a special order. Each decision closes with the qualitative factors that the arithmetic cannot capture but that could reverse it.
How an ACC-650 Topic 8 example is structured
The example works three decisions with one method. It opens by stating the relevance test, that a cost matters only if it differs between the alternatives. A second section works make or buy, comparing only avoidable costs and including any capacity freed as an opportunity. A third works a special order, using contribution against incremental cost and checking whether existing capacity is genuinely spare. A fourth works keep or drop, showing that allocated fixed costs continuing after the drop is what makes the answer counterintuitive. A fifth lists in each case what was excluded and why, which is where the reasoning becomes checkable. A closing section names the qualitative factors, since customer relationships and supplier dependence are real and the arithmetic does not hold them.
The relevance test stated once
A cost matters only if it differs between the alternatives, and every exclusion afterward follows from that.
Exclusions written down
The discipline is only visible when the paper says what it left out and why it could not change.
Opportunity cost included
Capacity used by a special order has an alternative value even though nobody issues an invoice for it.
Keep or drop shown counterintuitive
Allocated fixed costs continue after the drop, so removing a product with positive contribution makes things worse.
Qualitative factors that could reverse it
Supplier dependence and customer relationships are real and the arithmetic cannot hold them.
Where marks go in ACC-650 Topic 8
Including allocated fixed costs in a decision analysis is precisely what this closing topic sets out to stop, and it produces the recommendation to drop a product that was contributing toward those very costs. A second failure is omitting opportunity cost, most often in a special order that quietly displaces regular business at full price. Papers lose marks for excluding costs without saying so, since the exclusions are the analysis and an unexplained figure looks like an omission. Accepting a special order without checking whether capacity is genuinely spare ignores the condition the whole calculation rests on. Reaching a recommendation with no qualitative discussion treats a business decision as purely arithmetic, which few of these actually are.

ACC-650 Topic 8 questions, answered
Why can dropping a loss making product make things worse?
Because the product statement usually charges it with allocated fixed costs that will continue after it goes. If the product generates positive contribution, that contribution was helping to cover costs the firm still has, and removing it leaves the same fixed costs spread across fewer products. The relevant question is whether contribution is positive, not whether the allocated statement shows a profit.
When is a special order worth accepting?
When the price exceeds the incremental cost of producing it and the capacity is genuinely spare. Both conditions matter. If accepting the order displaces regular sales at full price, the lost contribution is an opportunity cost that belongs in the calculation and frequently reverses the answer. Orders accepted on incremental cost alone, with capacity assumed free, are the standard trap.
How do I handle factors I cannot put a number on?
Name them alongside the arithmetic rather than inside it. Becoming dependent on a single supplier, damaging a long standing customer relationship or losing an internal capability are real considerations that no figure captures. State the quantitative answer, then state which qualitative factors could reverse it and how large they would have to be. That reads as judgment rather than as hedging.
