Finally, some types of inventory flow into and out of the warehouse in a specific sequence, while others do not. For example, milk would need to be managed so that the oldest milk is sold first. In contrast, a car dealership has no control over which vehicles are sold because customers make specific choices based on what is available.
Ending inventory was made up of 75 units at $27 each, and 210 units at $33 each, for a total FIFO perpetual ending inventory value of $8,955. The specific identification method of cost allocation directly tracks each of the units purchased and costs them out as they are sold. In this demonstration, assume that some sales were made by specifically tracked goods that are part of a lot, as previously stated for this method. For The Spy Who Loves You, the first sale of 120 units is assumed to be the units from the beginning inventory, which had cost $21 per unit, bringing the total cost of these units to $2,520. Once those units were sold, there remained 30 more units of the beginning inventory. The second sale of 180 units consisted of 20 units at $21 per unit and 160 units at $27 per unit for a total second-sale cost of $4,740.
Inventory cost flow assumption definition
During the accounting period, Wexel sells 25 widgets from bucket A, each of which cost $25 to produce; 27 widgets from bucket B, each of which cost $27 to produce; and 30 widgets from bucket C, each of which cost $30 to produce. Regardless of which cost assumption is chosen, recording inventory sales using the perpetual method involves recording both the revenue and the cost from the transaction for each individual sale. As additional inventory is purchased during the period, the cost of those goods is added to the merchandise inventory account.
- Suppose the above company replaced the unit of inventory it sold for $40, and that replacement unit cost $33.
- The amount of the closing entry for ending inventory is obtained from the income statement.
- The resulting gross margin is a better indicator of management’s ability to generate income than gross margin computed using FIFO, which may include substantial inventory (paper) profits.
- These UPC codes identify specific products but are not specific to the particular batch of goods that were produced.

Cost of Goods Sold vs. Inventory
Companies that use the periodic system and want to apply the same cost to all units in an inventory account use the weighted average cost method. The weighted average cost per unit equals the cost of goods available for sale divided by the number of units available for sale. The LIFO costing assumption tracks inventory items based on lots of goods that are tracked in the order that they were acquired, so that when they are sold, the latest acquired items are used to offset the revenue from the sale. The following cost of goods sold, inventory, and gross margin were determined from the previously-stated data, particular to perpetual, LIFO costing. The FIFO costing assumption tracks inventory items based on lots of goods that are tracked, in the order that they were acquired, so that when they are sold the earliest acquired items are used to offset the revenue from the sale. The cost of goods sold, inventory, and gross margin shown in Figure 10.15 were determined from the previously-stated data, particular to perpetual FIFO costing.
Calculate the corrected cost of goods sold, net income, total assets and equity for 2015 and 2016. Opening inventory at January 1 amounted to 4,000 units at $11.90 per unit for Product A and 2,000 units at $13.26 per unit for Product B. An error in ending inventory is offset in the next year because one year’s ending inventory becomes the next year’s opening inventory.
LO2 – Explain the impact on financial statements of inventory cost flows and errors.
Transportation costs are commonly assigned to either the buyer or the seller based on the free on board (FOB) terms, as the terms relate to the seller. Transportation costs are part of the responsibilities of the owner of the product, so determining the owner at the shipping point identifies who should pay for the shipping costs. The seller’s responsibility and ownership of the goods ends at the point that is listed after the FOB designation.
1: Inventory Cost Flow Assumptions
This is achieved because the LIFO method assumes that the most recent inventory items are sold first. LO2 – Explain the impact on financial statements of inventory cost flows and errors. There are two components necessary to determine the inventory value disclosed on a corporation’s balance sheet. The first component involves calculating the quantity of inventory on hand at the end of an accounting period by performing a physical inventory count. The second requirement involves assigning the most appropriate cost to this quantity of inventory. Figure 5.8 highlights the relationship in which total cost of goods sold plus total cost of ending inventory equals total cost of goods available for sale.
Weighted Average Inventory Costing or Average Cost Inventory Method
This approach tends to yield average profit levels and average levels of taxable income over time. The gross profit percentage, rounded to the nearest whole percent, is 33% ($5,000/15,000). This means that for each dollar of sales, an average of $.33 is left to cover other expenses after deducting cost of goods sold.
FIFO, LIFO, and WAC Example
These costs will vary depending on the inventory cost flow assumption used. As we will see in the next sections, the cost of sales may also vary depending on when sales occur. Average cost flow assumption is a calculation companies use to assign costs to inventory goods, cost of goods sold (COGS), and ending inventory. how much will property taxes go up for adding a bedroom An average is taken of all of the goods sold from inventory over the accounting period and that average cost is assigned to the goods. Below, we will use the weighted average cost method and identify the difference in the allocation of inventory costs under a periodic and perpetual inventory system.
