Inventory & costs

IAS 2 Inventory Accounting Foundations

Understand inventory value through a worked IAS 2 example connecting purchases, cost of sales, quantity, ownership, cost and recoverability.

What you will take away

Inventory value differs from total purchases and total selling prices.

Assess quantity, rights, cost and condition as distinct questions.

The carrying amount may decline without any change in unit count.

A retailer faces three figures for its goods: SAR 72,000 paid to a supplier, SAR 120,000 displayed on price tickets and SAR 48,000 in the inventory report after the month's sales. Which is “inventory value”? Answering requires the reporting date, remaining quantity and method used to determine its cost. All three figures might be valid while describing different things.

Understanding IAS 2 starts with that distinction. Purchase cost is not expected revenue, and total ticket prices are not automatically the carrying amount. The standard measures inventory at the lower of cost and net realisable value. Applying that principle requires information connecting each item, its movements, its cost and its saleable condition.

From supplier invoice to profit report

Suppose the retailer buys 600 homogeneous units at a complete cost of SAR 120 each, totalling SAR 72,000, then sells 200 for SAR 190 each. There are no returns, opening inventory or additional costs in this example. The sold portion costs SAR 24,000, leaving 400 units costing SAR 48,000.

Revenue from the sale is SAR 38,000, producing gross profit of SAR 14,000 before other expenses. Charging the entire SAR 72,000 purchase to the month's expenses would distort that result because some goods remain unsold. Conversely, leaving sold units' cost in inventory would overstate both the asset and profit.

A simple reconciliation therefore matters: SAR 72,000 of available cost equals SAR 24,000 of cost of sales plus SAR 48,000 of remaining inventory. If those amounts do not agree, investigate missing or duplicate movements and unallocated costs instead of carrying an unexplained difference into the following month.

Four questions about the SAR 48,000

  • Does the quantity actually exist? A system report cannot replace checking locations and outstanding movements.
  • Do the units belong in this business's inventory? Review documents and terms, particularly for consignments and goods held by others.
  • Is the SAR 120 unit cost complete and explainable? Qualifying shipment services may have been received before their invoices arrived.
  • Is that cost expected to be recovered through sale? Damage or product obsolescence may reduce recovery below the recorded amount.

These are different questions; answering one does not settle the others. Counting 400 units supports quantity but does not establish condition or unit cost. Likewise, a supplier invoice supports a purchase transaction without independently proving that the entire quantity remains in the warehouse at the reporting date.

When the condition of the goods changes

Assume 50 of the remaining units now have an expected net recovery of SAR 90 each, compared with their SAR 120 unit cost. That portion indicates a reduction of SAR 30 per unit, or SAR 1,500. Assuming no other effect, the adjusted inventory amount becomes SAR 46,500.

The adjustment does not change the remaining quantity: there are still 400 units. This illustrates why quantity and value records should be distinguishable. Commercial responses might include repairing packaging, offering a promotion or negotiating a return, but each requires evidence, costs and timing. Simply keeping the old figure until conditions improve is not a substantiated plan.

A report that supports decisions rather than collecting numbers

A useful report shows quantity, cost, recent movement and condition, with a route back to supporting documents. Avoid combining dissimilar products into a large total that hides the problem. Rising aggregate inventory value can conceal a shortage of a popular item alongside an excess of another. Decisions need a level of detail useful to operations, with results subsequently aggregated for financial reporting.

At the end of a review, the responsible person should be able to explain the change between reporting dates: purchases, sales, returns, transfers and approved quantity or value adjustments. They need not memorise every number, but they should have a clear path to reconstruct it. That traceability turns a theoretical standard into information that can support pricing, purchasing and closing decisions.
