ACCT90004 Chap.5 Inventory, Gross Margin and Current Assets
Inventory, Gross Margin and Current Assets
Inventory decisions join quantities, costs, selling prices and channel economics. This chapter reconciles stock movements, calculates cost of goods sold and gross margin, and tests the effects of discounts or missing records on current assets. The method separates GST where required and keeps margin distinct from markup.
A strong response calculates the accounting result, explains the denominator used and then identifies the operating evidence needed before drawing a management conclusion.

Test the margin effect of a price cut
- 1Normal gross profit is $120 minus $48, which equals $72.
- 1Normal gross margin is $72 divided by $120, which equals 60%.
- 1Sale revenue is $120 multiplied by 80%, which equals $96, and sale gross profit is $48.
- 1Sale gross margin is $48 divided by $96, which equals 50%.

- The carrying cost of inventory recognised when related goods are sold.
- Gross profit
- Revenue less cost of goods sold.
- Gross margin
- Gross profit divided by revenue.
- Inventory shrinkage
- The shortfall between recorded inventory and inventory physically available.
Inventory, Gross Margin and Current Assets FAQ
Why are margin and markup different?
They use different denominators. Gross margin divides gross profit by sales revenue, while markup divides gross profit by inventory cost. A single transaction therefore produces different percentages even though revenue, cost and profit are unchanged.
Does a discount always reduce total profit?
A discount reduces profit per unit when unit cost is unchanged, but total profit also depends on additional volume and other channel costs. Calculate the new contribution first, then state what sales uplift would be required rather than assuming demand.
What evidence supports an inventory balance?
Useful evidence includes purchase and receipt records, sales records, physical counts, inventory reports, returns and adjustments. Differences should be reconciled to timing, damage, errors or loss before the reported quantity and carrying amount are accepted.
How should inventory advice go beyond a percentage?
Report the calculated margin change, identify the operational driver and state what further evidence would test the recommendation. Useful evidence may include volume, returns, fulfilment costs, stock ageing or physical counts. Do not infer demand or shrinkage solely from a margin or ledger difference.
Exam move
Begin each inventory problem with a movement schedule: opening units plus purchases or production, less units sold and other movements, equals closing units. Keep quantities separate from dollar costs until the flow is clear. For margin questions, write revenue, cost of goods sold and gross profit on separate lines before calculating a percentage. Label the denominator so margin and markup cannot be confused.
Practise discounts by solving the new price, unit gross profit, margin and break-even volume increase in that order. Include missing-record cases where you reconcile ledger quantities to a physical count and explain possible evidence rather than inventing a cause. Check whether stated prices include GST before comparing them.
Review each solution by testing units, signs and whether opening plus inflows minus outflows equals closing. Since the source only links a Topic 5 solution rather than providing a textual marking guide, use the visible method as a revision structure, not as a claim about examiner marks. Finish with mixed questions that require both arithmetic and a short recommendation grounded in the calculated margin.
Develop three linked schedules for each inventory case. The quantity schedule reconciles opening units, receipts, sales, returns, damage and closing count. The cost schedule assigns the supplied costs to units and derives cost of goods sold. The decision schedule compares revenue, gross profit and margin by channel or pricing choice.
Keeping these layers separate makes it easier to locate whether a difference comes from quantity, cost assignment or selling price. Practise translating discounts into both dollar gross profit and percentage margin, then calculate the extra units needed to preserve total gross profit when the facts permit. Change one input at a time to see which conclusions remain stable.
For missing stock, write several possible explanations and pair each with evidence rather than choosing theft without support. Reconcile system records to physical counts and preserve the reporting-date boundary for goods received or sold near period end. Add GST only according to the stated basis and keep it outside revenue and inventory comparisons when the facts require exclusion.
In review, recompute percentages from raw dollars and label margin versus markup. The closing paragraph should state the numerical result, the business consequence and a targeted next check, not a general claim that lower prices automatically improve or harm performance. Complete one no-calculator estimation before exact arithmetic; an implausible percentage should trigger a denominator and price-basis review immediately.
