To understand the use of LIFO in a perpetual inventory system, read “last-in, first-out (LIFO) method in a perpetual inventory system” article. Under last-in, first-out (LIFO) method, the costs are charged against revenues in reverse chronological order i.e., the last costs incurred are first costs expensed. In other words, it assumes that the merchandise sold to customers or materials issued to factory has come from the most recent purchases. The ending inventory under LIFO would, therefore, consist of the oldest costs incurred to purchase merchandise or materials inventory. “Periodic systems are better with unknowns. Not all periodic systems have computer systems attached since computer logic does not do well with many unknowns,” explains Relph. To make good business decisions, most business owners and managers need updated information on a very regular basis.

It sells 50 exotic plants and 25 rose bushes during the first quarter of the year for a total of 75 items. In LIFO periodic system, the 120 units in ending inventory would be valued using earliest costs. On December 31, 2016, a physical count of inventory was made and 120 units of material were found in the store room.

Major Differences – LIFO and FIFO (During Inflationary Periods)

A perpetual system is more sophisticated and detailed than a periodic system because it maintains a constant record of the inventory and updates this record instantaneously from the point of sale (POS). However, perpetual systems require your staff to perform regular recordkeeping. For example, in a periodic system, when you receive a new pallet of goods, you may not count them and enter them into stock until the next physical count.

Deducting the cost of sales from the sales revenue gives us the amount of gross profit. For example, suppose a shop sells one of the two identical pairs of shoes in its inventory. One pair cost $5 and was purchased in January, and the second pair was purchased in February and cost $6 unit.

The guide has everything you need to understand and use a periodic inventory system. You’ll find basic journal entries, formulas, sample problems, guidance, expert advice and helpful visuals. Two bathtubs were sold on September 9 but the identity of the specific costs to be transferred depends on the date on which the determination is made. A periodic system views the costs from the perspective of the end of the year, while perpetual does so immediately when a sale is made.

For these reasons, the LIFO method is controversial and considered untrustworthy by many authorities. This is why it is banned as an accounting practice outside the United States. Many countries, such as Canada, India and Russia are required to follow the rules set down by the IFRS (International Financial Reporting Standards) Foundation. The IFRS provides a framework for globally accepted accounting standards.


If you use a LIFO calculator as an ending inventory calculator, you will see that you keep the cheapest inventory in your accounts with inflation (and rising prices through time). In that sense, we will see a smaller ending inventory during inflation compared to a non-inflationary period. Notice how the cost of goods sold could increase if the last prices of the items the company bought also increase. What happens during inflationary times, and by rising COGS, it would reduce not only the operating profits but also the tax payment. LIFO is banned under the International Financial Reporting Standards that are used by most of the world because it minimizes taxable income.

As of January 15, we still have 30 units from beginning inventory and 30 units from the January 5 purchase. Preparing a schedule of LIFO layers before updating perpetual records for a sale is important in making sure you take COGS from the most recent layer. Take note that you have to repeat this step before you make entries to LIFO layers. This schedule will serve as your guide to what layer needs to be updated. Assume our physical inventory count reveals 80 units in ending inventory. Hence, the cost of ending inventory is $192, composed of four units in beginning inventory (4 units x $38 each) and one unit from purchases (1 x $40 each).


As a result, LIFO isn’t practical for many companies that sell perishable goods and doesn’t accurately reflect the logical production process of using the oldest inventory first. The valuation method that a company uses can vary across different industries. Below are some of the differences between LIFO and FIFO when considering the valuation of inventory and its impact on COGS and profits. Let’s compute the ending inventory step by step using the sample data taken from the inventory records of a company selling table tennis paddles. As indicated by the name itself, the LIFO method bases the COGS on the cost of the most recent purchases (last in). It means that recently purchased goods are expected to be expensed first or transferred to the COGS.

FIFO differs in that it leads to a higher closing inventory and a smaller COGS. LIFO is more popular among businesses with large inventories so that they can reap the benefits of higher cash flows and lower taxes when prices are rising. The example below has the same activities as above, except the company tracks each unit individually and what it purchased. Then, it performs a detailed physical inventory, reporting back each unit sold by the date the purchase was made. Record inventory sales by crediting the accounts receivable account and crediting the sales account. Record the purchase of inventory in a journal entry by debiting the purchase account and crediting accounts payable.

For the sale of one snowmobile, the company will expense the cost of the newer snowmobile – $75,000. Calculate the value of ending inventory, cost of sales, and gross profit for Lynda’s first six days of business based on the LIFO Method. The company made inventory purchases each month for Q1 for a total of 3,000 units. However, the company already had 1,000 units of older inventory that was purchased at $8 each for an $8,000 valuation. In other words, the beginning inventory was 4,000 units for the period.
