Inventory Valuation: Lower of Cost and Net Realisable Value

The Australian Accounting Standards Board (AASB 102) requires stock to be valued at the lower of cost and net realisable value on an item by item basis.

The cost price of stock is the total cost involved in bringing stock to its present location and condition ready for sale. The cost price of stock can be determined either using product costing or period costing (see previous post).

Net realisable value is the estimated amount the business expects to gain from the sale of the stock in the ordinary course of business.

Once measured, the lower of cost and net realisable value is the carrying amount the business recognises as an asset in the Balance Sheet. The accounting treatment prescribed by AASB 102 is shown below.


Information in this post is based on the attached CPA Australia fact sheet.

Inventory Valuation: Product Costs vs Period Costs

Stock (or inventory) is often the most significant asset a trading business holds. For a trading business it is their main source of earning revenue. In most cases stock on hand is valued at historical cost in the Balance Sheet, but how do we determine that cost? In many cases this is just the invoice price charged by the supplier. But in some cases there are other cost associated with the purchase of stock that need accounting for.

The value of stock in the Balance Sheet includes all costs incurred in order to bring stock into a condition and location ready for sale. However, in order to calculate the cost per item of stock, it is necessary to allocate these costs to individual units of stock.

Product costs

All costs incurred in getting stock to saleable condition which can be allocated to individual units of stock on a logical basis. Three main elements include raw materials, labour, factory overheads.

Period costs

All costs incurred for a period of time in getting stock to a saleable condition that can not be allocated to individual units of stock because there is no logical basis to do so. Sometimes classified into, marketing expenses, general (administrative) expenses and financial expenses.
