Stock Valuation: JAMB Principles of Accounts Questions, Answers & Notes

What Stock Valuation covers in the JAMB Principles of Accounts syllabus

Stock (inventory) is goods held for sale (or materials for production — raw materials, work-in-progress, finished goods). By the prudence concept, stock is valued at the lower of cost and net realisable value (NRV = estimated selling price − costs to complete and sell). Cost is measured by methods such as FIFO (First-In-First-Out — earliest goods sold first, so closing stock is at the latest prices), LIFO (Last-In-First-Out — most recent sold first) and weighted average (average unit cost); when prices rise, FIFO gives a higher closing stock value than LIFO. Stock valuation matters because overvaluing closing stock overstates gross profit and undervaluing it understates profit, and it affects both the trading account and the balance sheet (where closing stock is a current asset). Using the same method each year (consistency) allows fair comparison.

For Stock Valuation, JAMB expects you to be able to:

• Define stock and the lower-of-cost-and-NRV rule (prudence)
• Distinguish FIFO, LIFO and weighted average methods
• Explain the effect of stock valuation on profit and the balance sheet

Key facts & revision notes: Stock Valuation

These are the recurring points our Stock Valuation questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• Stock (inventory) is the goods a business holds for sale (or materials for production).
• The rule is to value stock at the lower of cost and net realisable value (prudence concept).
• Net realisable value = estimated selling price − estimated costs to complete and sell the goods.
• FIFO (First-In-First-Out) assumes the earliest goods bought are sold first.
• LIFO (Last-In-First-Out) assumes the most recently bought goods are sold first.
• Under FIFO, closing stock consists of the most recently purchased goods, valued at the latest prices.
• The weighted average method values stock using the average cost of the units available.
• Overvaluing closing stock reduces cost of goods sold, so it overstates gross profit.
• Undervaluing closing stock raises cost of goods sold, so it understates gross profit.
• Closing stock is a current asset in the balance sheet.
• Stocktaking is the physical counting and valuation of stock at the end of a period.
• Lower of cost (500) and NRV (450) = #450.
• Lower of cost (500) and NRV (600) = #500.
• The prudence (conservatism) concept requires stock to be valued at the lower of cost and NRV.
• A manufacturer holds raw materials, work-in-progress and finished goods.
• When prices rise, FIFO values closing stock at the latest (higher) prices, giving a higher value than LIFO.
• Incorrect stock valuation misstates profit (trading account) and current assets (balance sheet).
• This period's opening stock is the previous period's closing stock.
• Correct stock valuation is needed to determine profit and financial position accurately.
• Using the same valuation method each year (consistency) allows fair comparison of results.

Worked examples

Three Stock Valuation questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How Stock Valuation is tested in JAMB Principles of Accounts

Our Stock Valuation bank holds 20 questions (4 medium, 16 hard). JAMB Principles of Accounts typically returns to Stock Valuation year after year, so steady practice on this topic is high-value revision. Questions are multiple-choice with four options, and at UTME pace you get roughly 40 seconds each — which is why timed practice matters.

How to answer Stock Valuation questions

Work the stem first and predict the answer before you look at the options; then eliminate the ones that contradict the key facts above. Watch for “which is not…”, “all of the above” and “except” style stems, which are where rushed candidates lose easy marks on Stock Valuation. If a calculation or a precise definition is involved, work it from first principles rather than guessing from a half-remembered rule. When two options look right, re-read the stem for the qualifier that separates them — JAMB rarely repeats an option by accident. If you are still unsure, eliminate the two weakest choices to lift your odds, flag the question, and move on; never burn a full minute on one Principles of Accounts item when the exam gives you about forty seconds each. Then come back to flagged questions with whatever time remains. The single most reliable way to get faster at Stock Valuation is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Stock Valuation

The errors that cost marks on Stock Valuation are usually careless rather than conceptual: misreading a negative stem, confusing two similar terms, or rushing a definition you actually know. Candidates also over-rely on “expo” and last-minute cramming instead of understanding the topic — which fails the moment JAMB rephrases a familiar idea. Treat every option as a claim to be checked against the facts above, keep your working tidy for any calculation, and don’t change a considered answer on a hunch. Above all, revise Stock Valuation actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.
