Last In, First Out (LIFO)


Last In, First Out (LIFO) is an inventory management and valuation method that assumes the most recently acquired items are sold or used first. Under this system, the latest purchased items are recorded at the top of the inventory, and costs are calculated based on the prices of these assets. As a result, the remaining unsold inventory reflects the costs of the earliest purchased items.


The phonetics of the keyword “Last In, First Out (LIFO)” would be:/last ɪn, fɝst aʊt (laɪfoʊ)/ Breaking it down:- “Last” is pronounced /last/- “In” is pronounced /ɪn/- “First” is pronounced /fɝst/- “Out” is pronounced /aʊt/- “LIFO” is pronounced /laɪfoʊ/

Key Takeaways

  1. Last In, First Out (LIFO) is an inventory management method in which the most recently added items are sold or used first, while the oldest items in inventory remain unsold or unused.
  2. It leads to higher income during inflationary times, because goods sold are generally valued at higher costs. This reduces reported earnings and results in lower taxes.
  3. LIFO is not accepted under the International Financial Reporting Standards (IFRS), which could cause complications for businesses operating internationally or those planning to do so in the future.


The Last In, First Out (LIFO) method is an important concept in business and finance because it offers a unique approach to inventory valuation and cost flow assumptions. By allowing companies to allocate costs from the most recent inventory purchased or produced to outgoing sales, LIFO reduces the reported profit and tax liabilities in times of rising prices, thus providing tax advantages and improving cash flow. Furthermore, LIFO helps in matching current revenue with current costs and maintains better alignment with current market conditions. However, it is essential to consider that the method may result in a reduction of inventory value on the balance sheet due to the valuation of older items, potentially impacting future profits and financial ratios.


Last In, First Out (LIFO) is an inventory management and valuation technique commonly employed in finance and business operations. The primary purpose of LIFO is to provide a means of accounting for the latest inventory costs in a rapidly changing price environment. This method is particularly useful for companies that handle products with short shelf lives or those susceptible to obsolescence. By adopting the LIFO method, businesses allocate the most recent costs to goods sold, assuming that the most recently acquired items are sold first. This approach offers a better reflection of current market conditions, as well as optimizing value in volatile markets. Apart from its usefulness in aligning inventory costs with contemporary market trends, LIFO also serves as a tool of tax management for businesses. Utilizing LIFO in periods of rising prices results in higher costs of goods sold, thereby reducing the reported taxable income and taxes payable. Consequently, companies can effectively manage their tax liabilities by retaining more revenue for future growth and investment strategies. However, it should be noted that LIFO is prohibited under the International Financial Reporting Standards (IFRS) due to its potential to distort financial reporting, though it is still acceptable under the United States Generally Accepted Accounting Principles (US GAAP). The choice between LIFO, First In, First Out (FIFO), and other inventory valuation methods should ultimately depend on the specific needs and objectives of a business, taking into account both its operational landscape and regulatory environment.


1. Retail and Grocery Stores: In the retail and grocery industry, perishable items such as fruits, vegetables, and dairy products follow a LIFO inventory management system. When new stocks arrive, they are placed behind the existing ones, ensuring that the older products are sold first. This practice helps in reducing the chances of spoilage and waste. 2. Oil and Gas Industry: In the oil and gas industry, companies use LIFO for inventory management of their petroleum products. When new barrels of oil are acquired and stored in tanks, the last oil added will be the first to be extracted for sale or distribution, ensuring that oil reserves are used efficiently. 3. Warehousing and Storage Facilities: Businesses that offer warehousing and storage facilities for various goods, such as equipment, bulk materials, and pallets, might also utilize the LIFO method. As new items are added to the warehouse, they are placed in front of older items. This ensures that the most recently received inventory is the first to be accessed and moved out of the facility, promoting efficient inventory turnover and minimizing the potential for damage or obsolescence.

Frequently Asked Questions(FAQ)

What does Last In, First Out (LIFO) mean in finance and business?
Last In, First Out (LIFO) is an inventory valuation method used in finance and business, which assumes that the most recently acquired items (last in) are the first ones to be sold or used (first out). This accounting technique is mainly used to calculate the cost of goods sold and ending inventory.
How does LIFO affect financial statements?
LIFO affects both the balance sheet and the income statement. By using LIFO, a company reports a higher cost of goods sold, which results in lower gross profit and taxable income. On the balance sheet, LIFO assigns a lower value to the ending inventory, reducing the total value of assets. It is worth noting that LIFO is generally used when the prices of inventory items are increasing over time.
What is the purpose of using the LIFO inventory method?
The primary purpose of using the LIFO inventory method is to minimize taxable income and defer tax payments during periods of rising prices. By reporting higher costs of goods sold, businesses lower their reported profits, reducing the amount of income tax they need to pay.
How do you calculate LIFO?
To calculate LIFO, follow these steps:1. Identify the items sold in a given period and their purchase dates.2. Determine the cost of goods available for sale (starting inventory plus purchases made during the period).3. Using purchase dates, match the sold items to their respective costs, starting with the most recent purchases.4. Calculate the total cost of items sold using the matched costs.5. Subtract the total cost of items sold from the cost of goods available for sale to find the ending inventory value.
What are the advantages of using LIFO?
Some advantages of using LIFO include:1. Tax savings: In an environment with rising prices, LIFO leads to higher costs of goods sold, resulting in lower taxable income and tax payments.2. Better matching of costs and revenues: LIFO values current sales at current costs, providing a more accurate representation of profits during periods of changing prices.
What are the disadvantages of using LIFO?
Some disadvantages of using LIFO include:1. Lower inventory value: In times of rising prices, LIFO assigns lower value to ending inventory, which may not reflect the true market value of inventory items.2. Inaccurate inventory representation: LIFO can result in an outdated cost basis for inventory, as older inventory costs are used in valuation.3. Limited global acceptance: LIFO is prohibited by the International Financial Reporting Standards (IFRS), limiting its acceptance in countries that adopt these standards.
Can a company switch between LIFO and other inventory valuation methods?
While technically possible, switching between LIFO and other inventory valuation methods (such as FIFO or weighted average) is discouraged, as it could lead to inconsistencies in financial reporting over time. If a company chooses to switch inventory valuation methods, it must disclose the change and the related impact on its financial statements. Changing from LIFO could also have significant tax consequences, as it might lead to higher taxable income.
