Having more accurate tracking of inventory levels also provides a better way of monitoring problems such as theft. At a grocery store using the perpetual inventory system, when products with barcodes are swiped and paid for, the system automatically updates inventory levels in a database. As with FIFO, if the price to acquire the products in inventory fluctuates during the specific time period you are calculating COGS for, that has to be taken into account.
How to use LIFO for costs of goods sold calculation
Figure 10.18 shows the gross margin resulting from the LIFO perpetual cost allocations of $7,380. Figure 10.16 shows the gross margin, resulting from the FIFO perpetual cost allocations of $7,200. In January, Kelly’s Flower Shop purchases 100 exotic flowering plants for $25 each and 50 rose bushes for $15 each. Once March rolls around, it purchases 25 more flowering plants for $30 each and 125 more rose bushes for $20 each. It sells 50 exotic plants and 25 rose bushes during the first quarter of the year for a total of 75 items.
Business
- What happens during inflationary times, and by rising COGS, it would reduce not only the operating profits but also the tax payment.
- If prices are falling, earlier purchases would have cost higher which is the basis of ending inventory value under LIFO.
- It’s only permitted in the United States and assumes that the most recent items placed into your inventory are the first items sold.
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 of the services costs incurred to purchase merchandise or materials inventory. When you compare the cost of goods sold using the LIFO calculator, you see that COGS increases when the prices of acquired items rise.
Last In First Out Approach:
NetSuite offers a suite of native tools for tracking inventory in multiple locations, determining reorder points and managing safety stock and cycle counts. Find the right balance between demand and supply across your entire organisation with the demand planning and distribution requirements planning features. Calculate the beginning inventory as whatever stock remains from the previous period if you do not have a true beginning inventory. The COGS in a perpetual system is rolling and recalculated after each transaction, but you can use the COGS formula to calculate it for a period. A perpetual inventory system tracks goods by updating the product database when a transaction, such as a sale or a receipt, happens.
All the Methods and Formulas You Need to Get Started
When calculating inventory and Cost of Goods Sold using LIFO, you use the price of the newest goods in your calculations. The FIFO (“First-In, First-Out”) method means that the cost of a company’s oldest inventory is used in the COGS (Cost of Goods Sold) calculation. LIFO (“Last-In, First-Out”) means that the cost of a company’s most recent inventory is used instead.
Standard Costing
However, the cost of ending inventory presented in the balance sheet presents older costs. More importantly, users of the LIFO method say that using LIFO gives them tax savings since they report a lower taxable income. Each time new inventory is purchased, the total cost and quantity are updated, and a new average cost per unit is calculated.
When you sell products in a perpetual inventory system, the expense account increases and grows the costs of sales. Also called the cost of goods sold (COGS), the costs of sales are the direct expenses from the production of goods during a period. These costs include the labour and materials costs but leave off any distribution or sales costs. Huge businesses have difficulty performing the cycle counts that are necessary for a periodic system.
The only difference between the two cost flow concepts is how rapidly a cost layer is stripped away or replenished in the costing database. Under perpetual LIFO, there can be a great deal of this activity throughout a reporting period, with inventory layers being added and eliminated potentially as frequently as every day. This means that the costs at which items are sold could vary throughout the period, since costs are being drawn from the most recent of a constantly varying set of cost layers. After Corner Bookstore makes its third purchase of the year 2023, the average cost per unit will change to $88.125 ([$262.50 + $90] ÷ 4). As you can see, the average cost moved from $87.50 to $88.125—this is why the perpetual average method is sometimes referred to as the moving average method.
In this lesson, I explain the easiest way to calculate inventory value using the LIFO Method based on both periodic and perpetual systems. When using the perpetual system, the Inventory account is constantly (or perpetually) changing. In periods of deflation, LIFO creates lower costs and increases net income, which also increases taxable income.

LIFO is usually used by businesses dealing with non-perishable goods or products with long shelf lives. It may be advantageous for firms going through increased expenditures to utilize LIFO, as this could permit them to report lower gains and possibly lessen their tax duties. This method tends to provide more accurate results when dealing with perishable goods or products with short shelf lives since they need to be sold before their expiration dates.

The four paddles present at the beginning of the period at $38 each are still included in inventory at the end of the period. This is because the most recent paddles purchased were assigned to Cost of Goods Sold under the LIFO inventory method.
