This is because it must replace the inventory at a cost of at least $85. These results are logical, given the relationship between ending inventories and gross margin. However, in some sectors of the economy, such as electronics, prices have been falling. This is because, in today’s economy, rising prices are more common than falling prices.

Likewise, the retail inventory method estimates the cost of goods sold, much like the gross profit method does, but uses the retail value of the portions of inventory rather than the cost figures used in the gross profit method. A cost flow assumption is a method used to determine the cost of goods sold and the value of inventory on hand by estimating how costs are assigned to inventory as it is sold. As discussed in the appendix to Chapter 5, the ending inventory amount will be recorded in the accounting records when the income statement accounts are closed to the Income Summary at the end of the year. The amount of the closing entry for ending inventory is obtained from the income statement.
- The First-In, First-Out (FIFO) method assumes that the first unit making its way into inventory is sold first.
- In summary, in a situation of rising prices, FIFO and LIFO have opposite effects on the balance sheet and income statement.
- Although no shirt did cost $60, this average serves as the basis for both cost of goods sold as well as the cost of the item still on hand.
- In an economy where prices are rising, LIFO results in the lowest gross margin and the lowest ending inventory.
- This assumption probably would not be used extensively except for the LIFO conformity rule that prohibits its use for tax purposes unless also reported on the company’s financial statements.
- Buyers of such products are indifferent as to which specific item or lot they buy, and so the firm’s management is free to the specific lot(s) it desires.
1 Inventory Cost Flow Assumptions
Figure 6.8 highlights the relationship in which total cost of goods sold plus total cost of ending inventory equals total cost of goods available for sale. This relationship will always be true for each of specific identification, FIFO, and weighted average. When the periodic inventory system is used, the Inventory account is not updated when goods are purchased. Instead, purchases of merchandise are recorded in the general ledger account Purchases. Remember that the costs can flow differently than the physical flow of the goods.
6 Appendix B: Inventory Cost Flow Assumptions Under the Periodic System
Information found in financial statements is required to be presented fairly in conformity with U.S. Because several inventory cost flow assumptions are allowed, presented numbers can vary significantly from one company to another and still be appropriate. Understanding and comparing financial statements is quite difficult without knowing the implications of the method selected. LIFO, for example, tends to produce low-income figures in a period of inflation.
As there is an increasing emphasis in standard setting on valuation concepts, this approach would result in the most useful information for determining the value of the company. If profitability is more important to a financial-statement reader, then weighted average cost would be more useful, as more current costs would be averaged into income. Let’s assume that Wexel’s Widgets Inc. utilizes the average cost flow assumption when assigning costs to inventory items. 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. Companies have several methods at their disposal to roughly figure out which costs are removed from a company’s inventory and reported as COGS. This particular approach takes an average of the cost of items sold, leading to a mid-range COGs figure.
In contrast, financial reporting for decision makers must abide by the guidance of U.S. GAAP, which seeks to set rules for the fair presentation of accounting information. Because the goals are entirely different, there is no particular reason for the resulting financial statements to correspond to the tax figures submitted to the Internal an assumption about cost flow is used Revenue Service (IRS). Not surprisingly, though, significant overlap is found between tax laws and U.S. For example, both normally recognize the cash sale of merchandise as revenue at the time of sale. Depreciation, as just one example, is computed in an entirely different manner for tax purposes than for financial reporting.
As well, although taxes could be reduced in any given year through the cost flow assumption made, this is only a temporary effect, as all inventory will eventually be expensed through cost of goods sold. In a rising market, fifo is better for the balance sheet because it ensures that cogs will be higher than acb. In fact, fifo increases both cogs and ending inventory whereas the other two methods do not change ending inventory.In a falling market, lifo improves the balance sheet by increasing cogs and reducing ending inventory. This is because lifo increases both cogs and ending inventory whereas the other two methods do not change either of these figures. Let’s assume the Corner Bookstore had one book in inventory at the start of the year 2023 and at different times during 2023 it purchased four additional copies of the same book.
As before, we need to account for the cost of goods available for sale (5 books having a total cost of $440). With FIFO we assign the first cost of $85 to be the cost of goods sold. The remaining $355 ($440 – $85) will be the cost of the ending inventory. The $85 cost that was assigned to the book sold is permanently gone from inventory. Under the FIFO cost flow assumption, the first (oldest) costs are the first costs to leave inventory and be reported as the cost of goods sold on the income statement. The last (or recent) costs will remain in inventory and be reported as inventory on the balance sheet.
