Applying LIFO and Averaging to Determine Reported Inventory Balances
If you have a larger company with more complex inventory levels, you may want to consider implementing a perpetual system. The software you introduce into the workflow will make it easier for you to update and maintain your inventory. 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.
- When the inventory is received, along with the invoice from the vendor, payment is approved, and the cash and inventory accounts are updated accordingly.
- As we can see, the difference between the periodic and the perpetual systems under the weighted average cost method is only $364.
- Purchase Returns and Allowances is a contra account and is used to reduce Purchases.
- With perpetual LIFO, the last costs available at the time of the sale are the first to be removed from the Inventory account and debited to the Cost of Goods Sold account.
- FitTees sold 700 units of designer shirts and 900 units of jeans at $39 each.
When a sales return occurs, perpetual inventory systems require recognition of the inventory’s condition. This means a decrease to COGS and an increase to Merchandise Inventory. Under periodic inventory systems, only the sales return is recognized, but accounting definition not the inventory condition entry. A periodic inventory system updates and records the inventory account at certain, scheduled times at the end of an operating cycle. The update and recognition could occur at the end of the month, quarter, and year.
The major benefit of having multiple ledgers is that you can keep track of inventory balances and COGS throughout the year. Moreover, you aren’t required to perform frequent inventory counts because perpetual records always provide the latest information. Periodic inventory is the system in which the company does not track individual item movement but only performs physical counts at the month-end. The business only knows the inventory quantity at the beginning and month-end, but they will not know the exact amount in the middle of the month. Moreover, the company is not able to track the daily inventory movement.
The difference between perpetual LIFO and periodic LIFO
Under a periodic LIFO system, however, layers are only stripped away at the end of the period, so that only the very last layers are depleted.
Perpetual LIFO immediately determines the cost of this sale and reclassifies the amount to expense. On that date, the cost of the most recent two units ($130 each) came from the June 13 purchase. In contrast, a periodic LIFO system makes this same determination but not until December 31.
Under the LIFO Method
In this lesson, I explain the easiest way to calculate inventory value using the LIFO Method based on both periodic and perpetual systems. The cost of goods sold (which is reported on the income statement) is computed by taking the cost of the goods available for sale and subtracting the cost of the ending inventory. Let’s consider a fictional company, ABC Widgets, which sells widgets. We’ll use a simplified example where ABC Widgets buys and sells only one widget during a given accounting period. In a periodic LIFO system, inventory records are only updated at the end of a reporting period.

However, the identity of the last or most recent cost (expensed according to LIFO) depends on the perspective. Eric is an accounting and bookkeeping expert for Fit Small Business. He has a CPA license in the Philippines and a BS in Accountancy graduate at Silliman University. During the physical count, FitTees found that there are 225 units of designer shirts and 354 units of jeans on hand.
Different between Periodic and Perpetual
As can be seen here, periodic and perpetual LIFO do not necessarily produce identical numbers. Periodic Accounting is manually counting everything and reconciling how much you sold in the last year or period. This metric will inform you of lower-performing products, and your markdown thresholds, better preparing you for competition in the marketplace.

Formulas in Perpetual Inventory
The perpetual system is generally more effective than the periodic inventory system. That’s because the computer software companies use makes it a hands-off process that requires little to no effort. Products are barcoded and point-of-sale technology tracks these products from shelf to sale. These barcodes give companies all the information they need about specific products, including how long they sat on shelves before they were purchased. Perpetual systems also keep accurate records about the cost of goods sold and purchases. The two systems also differ in how they calculate Cost of Goods Sold (COGS).
It is a showcase of e-commerce inventory best practices and dives into the details of inventory management. The six inventory systems shown here for Mayberry Home Improvement Store provide a number of distinct pictures of ending inventory and cost of goods sold. As stated earlier, these numbers are all fairly presented but only in conformity with the specified principles being applied.
Under the FIFO Method
Moreover, the tracking of the cost of goods sold will be more accurate if compare to periodic. The cost of goods will be the total cost of goods being sold during the month, it not the balancing figure between the beginning and ending balance. It makes sense when we look at the formula, the beginning balance plus new purchase less ending must result as the sold item. This formula only uses to make assumptions and calculate the quantity of inventory being sold. To calculate the valuation of goods sold, it will be a problem when the cost we spend changes over time.
