Comparing FIFO with Other Inventory Valuation Methods


Inventory valuation is an essential aspect of any business’s financial management. It involves determining the cost of goods sold (COGS) and the value of remaining inventory. Several methods can be used to calculate inventory valuation, with each method having its advantages and disadvantages. In this article, we will compare the first-in, first-out (FIFO) method with other popular inventory valuation methods, discussing their pros and cons. By understanding these different approaches, businesses can make informed decisions when it comes to inventory management and financial reporting.

The FIFO Method

The FIFO method assumes that the first items recorded in inventory are the first ones sold. It means that the cost of goods sold reflects the cost of acquiring the oldest inventory. This method is widely used and considered more realistic for businesses that deal with perishable goods or products with limited shelf life.

Advantages of using the FIFO method include providing a better reflection of the current cost of goods sold, accurate valuation of ending inventory, and compatibility with international financial reporting standards (IFRS). Additionally, FIFO tends to result in fewer valuation fluctuations, providing more stable financial statements over time.

However, there are some drawbacks to consider. FIFO may lead to taxable income inflation when inventory costs increase. As the oldest and usually cheaper inventory is sold first, the remaining inventory is valued at higher costs, resulting in higher profitability and, consequently, higher taxes.

The LIFO Method

LIFO stands for last-in, first-out. Unlike FIFO, this method assumes that the last items recorded in inventory are the first ones sold. LIFO is often used in inflationary environments as it allows businesses to reduce their taxable income by taking advantage of rising costs.

One advantage of using LIFO is its potential tax savings. By assuming that the most recently acquired goods are sold first, companies can report lower profits and pay less in taxes. Another advantage is that LIFO better matches revenue with the current cost of goods sold in inflationary environments.

However, LIFO has some disadvantages. It may not align with the physical flow of inventory and can result in outdated costs assigned to inventory, potentially overvaluing it. Furthermore, LIFO is not compliant with IFRS, making it unsuitable for businesses that follow these international accounting standards.

The Weighted Average Method

The weighted average method calculates the average cost of all items in inventory, considering both new and old purchases. This method is straightforward, as it determines the average cost per unit and multiplies it by the quantity of items sold or remaining in inventory.

One advantage of using the weighted average method is that it smooths out the fluctuations in inventory costs. As new purchases are factored into the average, it creates a balance between recent and older costs. Additionally, this method is relatively simple to calculate and understand, making it accessible for small businesses.

However, the weighted average method may not accurately reflect the current cost of goods sold. Older and cheaper goods might still contribute to the average cost, even if recent purchases have a higher cost. Additionally, this method can result in higher pricing for products with high-cost inflation.

The Specific Identification Method

The specific identification method assigns a unique cost to each unit of inventory sold. This method is typically used for businesses with high-value, rare, or unique items, such as luxury goods, antiques, or custom-made products. Each item is individually tracked and matched with its corresponding cost.

The primary advantage of using the specific identification method is the accuracy of inventory valuation. It ensures that each item’s actual cost is recorded, resulting in precise financial statements. This method is also compatible with IFRS reporting standards.

However, this method requires meticulous tracking and record-keeping, which can be time-consuming and labor-intensive. It is not suitable for businesses with large quantities of low-cost items as the costs of tracking every unit can outweigh the benefits. Additionally, the specific identification method is not practical when dealing with perishable goods with short shelf lives.

Comparison and Considerations

When comparing the different inventory valuation methods, businesses should consider various factors. These include the nature of their products, industry standards, taxation implications, compatibility with accounting principles, and financial reporting requirements.

1. Nature of Products

The type of products a business deals with greatly influences the choice of inventory valuation method. Perishable goods may find the FIFO method more suitable, as it ensures older inventory is sold first. However, businesses dealing with unique or high-value items might opt for the specific identification method, enabling accurate cost matching.

2. Taxation

Tax implications can significantly impact the choice of inventory valuation method. In countries with inflationary economies, businesses may choose LIFO to reduce taxable income by assuming higher cost goods are sold first. Conversely, in countries with stable or deflationary economies, FIFO may be preferred to avoid taxable income inflation.

3. Accounting Principles

Businesses should consider compatibility with accounting principles when choosing an inventory valuation method. FIFO is generally accepted under both IFRS and generally accepted accounting principles (GAAP), making it suitable for companies that follow these standards. LIFO, on the other hand, is not recognized under IFRS.

4. Financial Reporting

The chosen inventory valuation method can affect the accuracy and stability of financial statements. FIFO provides a more stable cost flow and is less susceptible to fluctuations in inventory costs. Conversely, LIFO can result in significant valuation differences as costs continue to rise.


Inventory valuation is a critical aspect of financial management, and choosing the most appropriate method is crucial for accurate reporting and decision-making. The FIFO method offers advantages in reflecting the current cost of goods sold and stable financial statements. Conversely, LIFO provides tax savings but may not align with the physical flow of inventory. The weighted average method smoothes out fluctuations, while the specific identification method guarantees precise valuations for unique items. Businesses must consider the nature of their products, tax implications, accounting principles, and financial reporting requirements when deciding on an inventory valuation method.


Q1: Can I use different inventory valuation methods for different products within my business?

A1: Yes, businesses can use different inventory valuation methods for different products, especially if they have distinct characteristics or value. However, consistency is essential, and the chosen method should align with the nature of each product.

Q2: Which inventory valuation method is the most popular?

A2: The FIFO method is the most widely used and accepted inventory valuation method across various industries and accounting standards. Its compatibility with international reporting standards makes it popular among businesses.

Q3: Can I switch between inventory valuation methods?

A3: Generally, businesses should maintain consistency in their inventory valuation method to ensure comparability and accuracy over time. However, if a significant change is desired or required, proper justification and disclosure should accompany the change. This ensures transparency in financial reporting.

Q4: Are there any legal requirements for selecting an inventory valuation method?

A4: The choice of inventory valuation method is generally guided by accounting principles or standards, rather than specific legal requirements. Businesses should adhere to the accounting principles relevant to their jurisdiction and industry.

Q5: Does the inventory valuation method impact the overall profitability of a business?

A5: The inventory valuation method can impact the reported profitability of a business, primarily through the cost of goods sold calculation. For example, LIFO may lead to reduced taxable income, resulting in lower taxes. However, the overall profitability, excluding the tax implications, remains unchanged regardless of the chosen method.
