Last In, First Out (LIFO): Meaning and Advantages in Inventory Management

How LIFO works

• Inventory purchases: A company purchases 200 units of a product on June 1st at $10 each and an additional 300 units on July 15th at $12 each. The most recent purchase is the 300 units at $12 each, while the earlier purchase is the 200 units at $10 each.
• Sales transactions: When the company makes sales, it applies the LIFO principle to calculate COGS. Suppose it sells 350 units during the period.
• COGS calculation: Under LIFO, the first 300 units sold will be considered part of the most recent purchase (at $12 each), and the remaining 50 units will be from the earlier purchase (at $10 each). This means the COGS calculation would be:
  COGS = (300 units * $12 per unit) + (50 units * $10 per unit) = $3600 + $500 = $4100
• Ending inventory: After the sales, the company would have 150 units remaining in inventory, which will be valued based on the costs of the earlier purchase (at $10 each) until all of these units are sold.

Advantages of LIFO

• Inflation hedge: One of the key advantages of LIFO is its ability to act as an inflation hedge. During times of rising prices, the most recently purchased inventory is valued higher, resulting in a higher COGS and, consequently, lower reported profits. This can be advantageous for tax purposes, as it reduces taxable income and lowers tax liabilities.
• Realistic COGS calculation: LIFO provides a more accurate representation of the current market costs of goods sold. Since it attributes the most recent inventory costs to sales, it aligns well with the pricing of goods based on current market conditions.
• Higher profitability perception: In inflationary periods, the lower reported profits due to higher COGS under LIFO can create an illusion of lower profitability. However, this perception may be beneficial when dealing with stakeholders, investors, or lenders who assess a company’s financial performance based on reported profits.
• Matching revenue with expenses: LIFO helps in matching revenue with expenses more closely. When prices are rising, using the LIFO method for inventory valuation can result in a better matching of current costs with corresponding revenue, leading to a more accurate representation of the company’s financial performance.
• Tax benefits: During periods of inflation, the lower reported profits under LIFO can result in reduced tax liabilities, providing potential tax benefits for businesses.

Limitations of LIFO

• Non-reflective of physical flow: One of the main limitations of LIFO is that it may not accurately reflect the physical flow of goods within a business. In certain industries, the most recently acquired inventory may not necessarily be the first to be sold. This discrepancy between the actual flow of inventory and the LIFO assumption can lead to a distortion of cost figures in financial statements.
• Obsolete inventory costs: During prolonged periods of inflation, LIFO can result in older inventory costs remaining on the balance sheet for an extended period. As a consequence, the cost of goods sold (COGS) might not fully represent the current market value of inventory. This can potentially mislead stakeholders and investors who rely on financial statements for decision-making.
• Financial reporting challenges: Implementing the LIFO method can introduce complexities in financial reporting. Companies using LIFO may need to disclose the difference between LIFO and FIFO (or other valuation methods) for the benefit of users of financial statements. Additionally, during periods of significant inflation, the potential disparity between LIFO-based financial statements and those prepared under other inventory valuation methods could create confusion and raise concerns among stakeholders.
• Impact on cash flow: LIFO can result in higher inventory costs when inflation is prevalent. As a result, companies using LIFO may face increased tax liabilities due to lower reported profits. This can put pressure on cash flow, especially for businesses with tight operating margins.
• International financial reporting standards (IFRS) limitations: In some countries, the use of LIFO is not allowed under the International Financial Reporting Standards (IFRS). This limitation can create challenges for multinational companies that need to comply with different accounting regulations in various jurisdictions.

LIFO vs. FIFO

• COGS calculation: The primary difference between LIFO and FIFO lies in the calculation of the cost of goods sold (COGS). Under LIFO, the most recent inventory costs are used for COGS, resulting in higher expenses during periods of inflation. Conversely, FIFO assumes that the oldest inventory is sold first, leading to lower COGS during inflationary periods.
• Tax implications: LIFO can have significant tax implications, especially during inflation. Due to higher COGS under LIFO, reported profits are reduced, leading to lower tax liabilities. On the other hand, FIFO can result in higher reported profits and, subsequently, higher tax payments.
• Physical flow: FIFO more closely aligns with the physical flow of inventory in many businesses. This means that the cost of goods sold under FIFO often represents the actual order in which items were sold. In contrast, LIFO may not accurately mirror the actual flow of goods, which can be a limitation in industries where inventory movement is critical.
• Inflationary environments: LIFO tends to be favored during periods of inflation because it reduces taxable income and can provide a more realistic reflection of costs when prices are rising. In contrast, FIFO may lead to higher taxable income during inflationary periods due to lower COGS.
• Use cases: LIFO is commonly used in industries where inventory costs are significantly impacted by inflation, such as the petroleum and metal industries. On the other hand, FIFO is popular in industries with perishable or time-sensitive goods and where the order of sale is critical, such as the food and electronics sectors.

Financial ratios

• Gross profit margin: With higher COGS due to LIFO, the gross profit margin, which measures the percentage of revenue retained after accounting for the cost of goods sold, may be lower than in other accounting methods.
• Inventory turnover: LIFO’s lower inventory values can lead to a higher inventory turnover ratio, which indicates how efficiently a company manages its inventory. This may not always accurately represent the true efficiency, given the outdated inventory costs.
• Current ratio: The current ratio, which measures a company’s short-term liquidity, can be impacted by the lower inventory value under LIFO, potentially affecting the overall assessment of the company’s financial health.
