Understanding Inventory Valuation
Inventory valuation is the process of assigning a monetary value to the stock of goods a business holds at the end of an accounting period. This value is crucial because inventory is a current asset and appears on the balance sheet. The valuation affects the cost of goods sold (COGS) and, consequently, the gross profit and net profit reported in the income statement.
Inventory must be valued carefully to avoid overstating assets or profits. Overvaluation can mislead stakeholders about the company’s financial health, while undervaluation can understate profitability and asset worth. Therefore, accounting standards require inventory to be valued at the lower of its historical cost or its net realisable value (NRV).
- Inventory is a current asset on the balance sheet.
- Inventory valuation affects profit calculation.
- Accurate valuation prevents misleading financial statements.
Defining Cost and Net Realisable Value (NRV)
The 'cost' of inventory includes all expenses incurred to bring the goods to their present location and condition. This typically means purchase price plus any additional costs such as import duties, transport, and handling fees.
Net realisable value is the estimated selling price of the inventory in the ordinary course of business, less any estimated costs necessary to make the sale, such as completion, marketing, and distribution costs.
For example, if a batch of goods cost $1000 to purchase and prepare for sale, but due to damage the expected selling price is $900 and selling costs are $50, the NRV is $850 ($900 - $50). Since $850 is lower than $1000, the inventory should be valued at $850.
- Cost includes purchase price and costs to bring inventory to saleable condition.
- NRV = Estimated selling price - Costs to sell.
- Inventory is valued at the lower of cost or NRV.
Applying the Lower of Cost or NRV Method
To value inventory using this method, compare the cost and NRV for each inventory item or category. The value recorded in the accounting records and financial statements is the lower figure.
This approach ensures that inventory is not overstated, reflecting potential losses from damaged, obsolete, or unsellable stock.
For example, a business has inventory items as follows: Item A cost $500, NRV $480; Item B cost $300, NRV $350. Item A is valued at $480 (lower of $500 and $480), Item B at $300 (lower of $300 and $350). The total inventory value is $780.
- Compare cost and NRV for each item.
- Record inventory at the lower value.
- Prevents overstatement of assets and profits.
Preparing Basic Inventory Valuation Statements
An inventory valuation statement summarises the valuation of inventory at the end of the accounting period. It lists inventory items, their cost, NRV, and the value used in the financial statements.
The statement helps verify calculations and provides transparency for auditors and stakeholders.
Example:| Item | Cost | NRV | Valuation | |------|-------|------|------------| | A | $500 | $480 | $480 | | B | $300 | $350 | $300 | | Total| $800 | $830 | $780 |
- List inventory items with cost and NRV.
- Select the lower value for each item.
- Sum the valuations for total inventory value.
Impact of Inventory Valuation on Financial Statements
Inventory valuation directly affects the cost of goods sold (COGS) and gross profit. If inventory is overstated, COGS is understated, inflating gross profit and net profit.
Profit figures influence retained earnings and equity on the balance sheet. Overstated profits increase equity incorrectly.
Asset valuation is also affected because inventory is a current asset. Overvaluation misrepresents the company’s financial position, potentially misleading investors, creditors, and management decisions.
- Inventory valuation affects COGS and gross profit.
- Profit impacts equity through retained earnings.
- Accurate valuation ensures truthful financial position.

Active recall
Quick check
1. What two values must be compared to value inventory?
The cost of the inventory and its net realisable value (NRV).
2. How is net realisable value calculated?
Estimated selling price minus any costs necessary to make the sale.
3. Why is inventory valued at the lower of cost or NRV?
To avoid overstating inventory value and profits, ensuring financial statements are accurate.
4. What happens to gross profit if inventory is overvalued?
Gross profit is overstated because cost of goods sold is understated.
5. How does inaccurate inventory valuation affect equity?
It misstates profit, which affects retained earnings and thus equity, leading to incorrect asset valuation.
