When managing inventory, accounting professionals typically use two primary methods: FIFO (First In, First Out) and LIFO (Last In, First Out). These methods serve as the backbone for determining the cost of inventory and directly impact profitability, taxes, and financial reporting. While FIFO is often preferred due to its adherence to common consumption patterns, LIFO has its own merits, especially in specific economic conditions.
In this blog, we will explore both methods in detail, compare them, and provide examples to demonstrate their impact on a company’s financial health. By the end of this post, you’ll have a clear understanding of the key differences and benefits of each method.
What is FIFO?
FIFO (First In, First Out) assumes that a company sells or consumes the oldest goods in its inventory first. This method reflects the natural flow of goods for businesses that deal with perishable items or goods that lose value over time. Using FIFO ensures that a company’s inventory turnover accurately reflects the timeline of goods acquisition.
Characteristics of FIFO:
- The method ensures that the goods acquired first are the ones recorded as being sold first.
- The accounting records report the cost of older inventory first. Newer stock remains in inventory for future valuation.
- Businesses often use this method for perishables or items with limited shelf life.
What is LIFO?
LIFO (Last In, First Out), on the other hand, assumes that companies consume or sell the most recently acquired items first. Industries with significant fluctuations in the cost of goods typically use this method. Companies often favor LIFO for its tax advantages in environments with rising prices, as it lowers reported profits by attributing higher costs to the cost of goods sold (COGS).
Characteristics of LIFO:
- The newest inventory is accounted for first when calculating the cost of goods sold.
- Older inventory remains on the books, which could skew the value of a company’s assets.
- This method is preferred by companies aiming to minimize taxable income during inflationary periods.
Understanding the Difference Between FIFO and LIFO
While FIFO and LIFO serve the same purpose in determining inventory value and cost of goods sold, they function differently, particularly in environments where the cost of inventory fluctuates. Let’s take a closer look at how these differences manifest in real-world scenarios.
If inventory costs remain constant, there would be no significant difference between the two methods. However, in the real world, prices often change, and this can have a big impact. In times of rising prices, LIFO can help companies reduce taxable income by reporting higher COGS, whereas FIFO results in lower COGS and higher taxable income.
FIFO vs. LIFO Example
Let’s take a look at an example to further illustrate the differences between these two methods.
- A company purchases 100 units of inventory at $10 each.
- They purchase another 100 units later at $15 each.
If the company uses the LIFO method and sells 100 units, the calculation would look like this:
LIFO COGS = 100 units × $15 = $15,000
If the company uses the FIFO method, the cost would be:
FIFO COGS = 100 units × $10 = $10,000
In this scenario, LIFO shows a higher cost of goods sold, which reduces the company’s reported profit. This is the key benefit of LIFO—during periods of inflation, it can help reduce taxable income. However, FIFO provides a clearer picture of the company’s inventory valuation, as it reflects the cost of the older, lower-priced items.
Advantages and Disadvantages of FIFO and LIFO
Advantages of FIFO:
- Realistic Flow of Goods: FIFO mimics the natural consumption pattern of perishable or time-sensitive goods. Businesses like supermarkets and pharmacies naturally follow this method to ensure their oldest inventory is sold first.
- Accurate Inventory Valuation: With FIFO, the inventory on the balance sheet is valued using the most recent prices, which better reflects the current market value of the inventory.
- International Acceptance: Many global accounting standards, such as the International Financial Reporting Standards (IFRS), favor FIFO. This makes it the go-to method for multinational corporations.
Disadvantages of FIFO:
- Higher Taxes: In inflationary environments, FIFO can lead to higher taxable income since older, lower-cost inventory is used first, resulting in lower COGS and higher profits.
- Not Ideal for Inflation: For businesses experiencing significant price increases, FIFO may overstate the company’s profitability, which could result in paying more taxes.
Advantages of LIFO:
- Tax Benefits: During inflationary times, LIFO allows companies to match the rising costs of inventory with revenues, resulting in higher COGS and lower profits. This helps to defer taxes.
- Matching Costs with Current Revenues: Since LIFO uses the most recent costs, it aligns the company’s expenses more closely with current market prices.
Disadvantages of LIFO:
- Outdated Inventory Valuation: LIFO leaves older inventory on the balance sheet, which may not accurately reflect its market value. This can distort financial statements.
- Compliance Issues: LIFO is prohibited under the IFRS, which makes it unsuitable for companies operating in countries that follow these standards. Additionally, companies that switch from LIFO to FIFO must follow strict tax and accounting regulations.
- Complex Inventory Tracking: LIFO can make it harder for businesses to track their inventory accurately, particularly if prices fluctuate frequently.
The Impact of FIFO vs. LIFO on Financial Statements
The choice between FIFO and LIFO affects not only profits and taxes but also the value of inventory on the balance sheet and the gross profit margin.
- FIFO results in a higher ending inventory value during inflationary times because the most recent and more expensive items are still in stock.
- LIFO results in a lower ending inventory value, as older and often cheaper items remain in the inventory.
Thus, if inventory prices are rising, FIFO increases the gross margin and inventory valuation, while LIFO results in a lower gross margin and lower taxes. However, in times of deflation, these effects reverse.
Real-World Example: Choosing Between FIFO and LIFO
Consider a grocery store chain that purchases fresh produce daily. The store naturally operates on a FIFO basis because older items must be sold before they spoil. In this scenario, FIFO reflects the actual movement of goods, making it the ideal method.
On the other hand, an oil company may choose LIFO to account for the significant fluctuations in oil prices. By using LIFO, the company can ensure that its COGS reflects the most recent, higher-priced purchases, thus reducing taxable income during periods of rising prices.
Conclusion: Which Method is Right for Your Business?
Choosing between FIFO and LIFO depends on the nature of your business and the economic environment. FIFO is generally favored by businesses that deal with perishables or aim to present an accurate picture of inventory value. It also has international recognition and complies with IFRS.
LIFO, while useful for reducing taxes during inflationary periods, leads to outdated inventory valuations and faces bans in many countries. Companies using LIFO must also be aware of the complexities it adds to inventory tracking and compliance.
When deciding between FIFO and LIFO, evaluating your company’s unique needs, the economic climate, and the potential tax implications is essential.
