Periodic Inventory vs Perpetual Inventory: What’s the Difference?
In addition, a method must be applied to monitor inventory balances (either periodic or perpetual). Six combinations of inventory systems can result from these two nonrefundable decisions. With any periodic system, the cost flow assumption is only used to determine the cost of ending inventory so that cost of goods sold can be calculated.
- A perpetual inventory system automatically updates and records the inventory account every time a sale, or purchase of inventory, occurs.
- Retailers that use the perpetual system often make it a practice to count inventory (or at least a sample of inventory) to make adjustments for shrinkage.
- Purchases during the quarter amounted to $18,000, and at the end of the quarter, inventory was counted at $42,000.
- Periodic means that the Inventory account is not routinely updated during the accounting period.
- These formulas include COGS, economic order quantity (EOQ), weighted average cost, and gross profit.
- Periodic inventory is one that involves a physical count at various periods of time while perpetual inventory is computerized, using point-of-sale and enterprise asset management systems.
For a perpetual inventory system, the adjusting entry to show this difference follows. This example assumes that the merchandise inventory is overstated in the accounting records and needs to be adjusted downward to reflect the actual value on hand. Square accepts many payment types and updates accounting records every time a sale occurs through a cloud-based application.
Example of the Difference between Perpetual LIFO and Periodic LIFO
The perpetual system may be better suited for businesses that have larger, more complex levels of inventory and those with higher sales volumes. For instance, grocery stores or pharmacies tend to use perpetual inventory systems. This system allows the company to know exactly how much inventory they have at any specific time period.

- In the following section, we’ll illustrate the difference between the periodic inventory system and perpetual inventory system by showing the journal entries while using the FIFO cost flow assumption.
Remember that the costs can flow differently than the physical flow of the goods. For example, if the Corner Bookstore uses the FIFO cost flow assumption, the owner may sell any copy of the book but report the cost of goods at the first/oldest cost as shown in the exhibit that follows. Under Periodic LIFO, the inventory and COGS are updated at the end of the accounting period, not continuously. If inventory is central to your business, it must be managed, and to do that it, must be measured.
What is the Difference between Perpetual LIFO and Periodic LIFO?
Accountingo.org aims to provide the best accounting and finance education for students, professionals, teachers, and business owners. In a period of falling prices, the value of ending inventory under LIFO method will be lower than the current prices. The first thing we need to calculate is the units of ending inventory. On the LIFO basis, we will value the cost of the shoes sold on the most recent purchase cost ($6), whereas the remaining pair of shoes in inventory will be valued at the cost of the earliest purchase ($5). If you’re new to accountancy, calculating the value of ending inventory using the LIFO method can be confusing because it often contradicts the order in which inventory is usually issued. When I worked at a restaurant in high school, key items were counted every single night.
4 Merging Periodic and Perpetual Inventory Systems with a Cost Flow Assumption
Comparing the two systems, a perpetual inventory system and its counterpart, a periodic inventory system, is essential to understand their respective benefits. Both systems are methods for tracking and managing stock levels in businesses; however, they differ significantly in their approach. A perpetual inventory system is an advanced method of tracking and managing the stock levels of goods in real time. This system continuously updates inventory records as transactions occur, providing businesses with accurate information on their available stock at any given time. Throughout this guide, you’ll learn about the key differences between a perpetual system and periodic inventory systems. We’ll also discuss the pros and cons of using a perpetual inventory system in various scenarios.
Last-In First-Out (LIFO Method)
We will use the valuation methods such as FIFO, LIFO, and Weighted average. A perpetual inventory system automatically updates and records the inventory account every time a sale, or purchase of inventory, occurs. You can consider this “recording as you go.” The recognition of each sale or purchase happens immediately upon sale or purchase. Kroger apparently monitors its inventory on a daily basis using FIFO and arrived at a final cost of $5,793 million. However, at the end of that year, the company took a physical inventory and applied the LIFO cost flow assumption to arrive at a reported balance that was $827 million lower. The reduced figure was used for reporting purposes because of the LIFO conformity rule.
Because this is a perpetual average, a journal entry must be made at the time of the sale for $87.50. The $87.50 (the average cost at the time of the sale) is credited to Inventory and is debited to Cost of Goods Sold. The balance in the Inventory account will be $262.50 (3 books at an average cost of $87.50). Each time this figure is found by dividing the number of units on hand after the purchase into the total cost of those items.

If your business deals with high-value items or products that sell quickly, using a perpetual inventory system allows you to maintain accurate and real-time stock levels. This helps prevent stockouts and ensures optimal customer satisfaction. Perpetual
