There are several different inventory cost methods that businesses can use to calculate the cost of their inventory. Some of the most common methods include:
1. First In, First Out (FIFO): This method assumes that the first items purchased are the first items sold. This means that the cost of goods sold is based on the cost of the oldest inventory in stock, while the value of the ending inventory is based on the cost of the most recent purchases.
2. Last In, First Out (LIFO): This method assumes that the last items purchased are the first items sold. This means that the cost of goods sold is based on the cost of the most recent inventory purchases, while the value of the ending inventory is based on the cost of the oldest inventory in stock.
3. Weighted Average Cost: This method calculates the cost of goods sold and the value of the ending inventory by taking the average cost of all inventory items in stock. This method is often used when inventory costs fluctuate frequently.
4. Specific Identification: This method involves tracking the cost of each individual item in inventory and matching it to the specific item sold. This method is often used for high-value or unique items.
5. Retail Inventory Method: This method is commonly used by retailers and involves calculating the cost of goods sold and the value of the ending inventory based on the retail price of the items and a predetermined cost-to-retail ratio.
Each of these inventory cost methods has its own advantages and disadvantages, and the method chosen by a business will depend on factors such as the nature of the inventory, the industry, and regulatory requirements.

Inventory Cost Methods
Inventory cost methods determine the cost of the inventory sold and the ending inventory balance. The choice of method can significantly impact financial statements and tax liability.
1. First-In, First-Out (FIFO)
- Assumes that the oldest inventory is sold first. - Beginning inventory and purchases made first are considered sold first. - Ending inventory reflects the cost of the most recent purchases.
Advantages: - Provides a more accurate picture of current cost of goods sold (COGS) and current inventory value. - Less likely to result in inventory obsolescence or write-offs.
Disadvantages: - Can result in higher COGS and lower net income in periods of rising prices. - May not reflect the actual flow of goods in some industries.
2. Last-In, First-Out (LIFO)
- Assumes that the most recent inventory is sold first. - Purchases made last are considered sold first. - Ending inventory reflects the cost of the oldest purchases.
Advantages: - Can provide lower COGS and higher net income in periods of rising prices. - Helps reduce the impact of inflation on financial statements.
Disadvantages: - Can lead to lower COGS and higher net income in periods of falling prices. - May result in inventory obsolescence or write-offs. - Not acceptable for tax reporting in some countries.
3. Weighted Average Cost
- Calculates an average cost for all inventory items based on the costs of all purchases made during a period. - This average cost is used to value both sales and ending inventory.
Advantages: - Provides a more stable COGS and inventory value over time. - Less likely to result in inventory obsolescence or write-offs.
Disadvantages: - May not accurately reflect the current cost of purchases. - Can be more complex to calculate than FIFO or LIFO.
4. Specific Identification
- Assigns the actual cost of each specific inventory item to the sale or ending inventory. - Typically used for unique or high-value items.
Advantages: - Provides the most accurate valuation of specific inventory items. - Eliminates the risk of inventory obsolescence or write-offs.
Disadvantages: - Can be difficult and time-consuming to track individual inventory items. - Not practical for large or diverse inventory items.
Selection Factors:
The choice of inventory cost method depends on various factors, including:
- Industry practices - Nature and flow of inventory - Tax implications - Financial reporting objectives - Accuracy and reliability of cost data
