The correct option for the question regarding which inventory valuation method typically results in the highest ending inventory value during periods of rising prices is:
A. First-In, First-Out (FIFO)
Detailed Explanation
- Understanding Inventory Valuation Methods:
- First-In, First-Out (FIFO): This method assumes that the oldest inventory items are sold first. Therefore, the ending inventory consists of the most recently purchased items.
- Last-In, First-Out (LIFO): This method assumes that the most recently purchased items are sold first. Thus, the ending inventory consists of the oldest items.
- Weighted Average Cost: This method averages the cost of all inventory items available for sale during the period and applies this average cost to both the cost of goods sold and ending inventory.
-
Specific Identification: This method tracks the actual cost of each specific item of inventory. It is often used for unique or high-value items.
-
Impact of Rising Prices:
- In periods of rising prices (inflation), the cost of newer inventory is higher than that of older inventory.
- FIFO results in the most recent (and therefore higher) costs being assigned to the ending inventory. This means that the ending inventory value will reflect the higher prices of the most recently purchased items.
-
Conversely, LIFO would assign the higher costs to the cost of goods sold (COGS), leaving the older, lower-cost items in ending inventory, which results in a lower ending inventory value.

Example Calculation:
- Suppose a company has the following inventory purchases:
- 100 units at $10 each (oldest)
- 100 units at $15 each (newest)
- If the company sells 150 units:
- Under FIFO, the COGS would be:
- 100 units at $10 = $1,000
- 50 units at $15 = $750
- Total COGS = $1,750
- Ending Inventory = 50 units at $15 = $750
- Under LIFO, the COGS would be:
- 100 units at $15 = $1,500
- 50 units at $10 = $500
- Total COGS = $2,000
- Ending Inventory = 100 units at $10 = $1,000
-
As seen, FIFO results in a higher ending inventory value ($750) compared to LIFO ($1,000).
-
Why Other Options Are Incorrect:
- B. Last-In, First-Out (LIFO): As explained, LIFO results in lower ending inventory values during periods of rising prices because it uses the costs of older inventory for the ending balance.
- C. Weighted Average Cost: This method smooths out price fluctuations by averaging costs. While it may provide a middle ground, it does not typically yield the highest ending inventory value during inflationary periods compared to FIFO.
- D. Specific Identification: This method can yield varying results depending on the specific items sold and their costs. However, it does not inherently favor higher or lower values in the same way FIFO does during inflation.
Common Pitfalls
- Students often confuse FIFO and LIFO, especially regarding their impact on financial statements during inflation.
- Misunderstanding the implications of average cost methods can lead to incorrect assumptions about inventory valuation.
- Not considering the economic environment (inflation vs. deflation) when evaluating inventory methods can lead to incorrect conclusions.
Revision Summary
- FIFO results in the highest ending inventory value during rising prices because it uses the most recent (higher) costs for ending inventory.
- LIFO results in lower ending inventory values as it uses older (lower) costs.
- Weighted Average Cost provides a middle ground and does not typically yield the highest value in inflation.
- Specific Identification varies based on actual costs and does not consistently favor higher or lower values.
