Application of Different Cost Flow Assumptions FIFO and LIFO

Note that it is not the oldest item that is necessarily sold but rather the oldest cost that is reclassified to cost of goods sold. No attempt is made to determine which shirt was purchased by the customer. Here, because the first shirt cost $50, the following entry is made to record the expense and reduce the inventory. The full disclosure principle states that a business must report any business activities that could affect what is reported on the financial statements.

Table 3.1 shows the normal balances and increases for each account type. The time period assumption states that a company can present useful information in shorter time periods, such as years, quarters, or months. The information is broken into time frames to make comparisons and evaluations easier.

Weighted average cost method

When an account produces a balance that is contrary to what the expected normal balance of that account is, this account has an abnormal balance. Let’s consider the following example to better understand abnormal balances. This problem will carry through several chapters, building in difficulty. It allows students to continuously practice skills and knowledge learned in previous chapters. Following is a continuation of our interview with Robert A. Vallejo, partner with the accounting firm PricewaterhouseCoopers. We’re firm believers in the Golden Rule, which is why editorial opinions are ours alone and have not been previously reviewed, approved, or endorsed by included advertisers.

• Therefore, if the gross profit percentage is known, the dollar amount of ending inventory can be estimated.
• However, the LIFO conformity rule joins these two at this one key spot.
• Knowledgeable decision makers can easily make this adjustment for themselves to help in evaluating a company.
• Other examples of such firms are furniture companies, antique stores, and coin and stamp dealers.
• For an illustration of the cost flow assumption, see Explanation of Inventory and Cost of Goods Sold.

It demonstrates pricing policies and fluctuations often indicate policy changes or problems in the market. The average number of days in inventory and the inventory turnover both help decision makers know the length of time a company takes to sell its merchandise. Traditionally, a slowing down of sales is bad because inventory is more likely to be damaged, lost, or stolen. Companies that sell inventory choose a cost flow assumption such as FIFO, LIFO, or averaging. In addition, a method must be applied to monitor inventory balances (either periodic or perpetual).

Applying Cost Flow Assumptions

For example, a company might choose to use the LIFO assumption during periods of inflation, when prices are rising. This results in a lower reported COGS, which can boost profitability. A periodic LIFO inventory system begins by computing the cost of ending inventory at the end of a period and then uses that figure to calculate cost of goods sold. Perpetual LIFO also transfers the most recent cost to cost of goods sold but makes that reclassification at the time of each sale. A weighted average inventory system determines a single average for the entire period and applies that to both ending inventory and the cost of goods sold.

Overview: What are cost flow assumptions?

The report of the independent auditor never assures decision makers that financial statements are “presented fairly.” That is a hopelessly abstract concept like truth and beauty. Thus, for this men’s clothing store, all the following figures are presented fairly but only in conformity with the cost flow assumption used by the reporting company. In Chapter 6 “Why Should Decision Makers https://accounting-services.net/what-are-cost-flow-assumptions/ Trust Financial Statements? Let’s assume that Wexel’s Widgets Inc. utilizes the average cost flow assumption when assigning costs to inventory items. Cost of goods available for sale must be allocated between cost of goods sold and ending inventory using a cost flow assumption. Specific identification allocates cost to units sold by using the actual cost of the specific unit sold.

Which of these is most important for your financial advisor to have?

With that assumption, the remaining inventory would be 20 pairs at $30 and 29 pairs at a cost of $35 each. It is very difficult for managers to manipulate income with this method, as the effects of rising or falling prices will be averaged over both the goods sold and the goods remaining on the balance sheet. As well, for goods that are similar and interchangeable, this method may most closely represent the actual physical flow of those goods. A potential or existing investor wants timely information by which to measure the performance of the company, and to help decide whether to invest. Because of the time period assumption, we need to be sure to recognize revenues and expenses in the proper period. This might mean allocating costs over more than one accounting or reporting period.

Why do companies use cost flow assumptions to cost their inventories?

They eventually agreed to recommend that LIFO be allowed for income tax purposes but only if the company was also willing to use LIFO for financial reporting. If you’re looking for a cost flow assumption that smooths your product costs over time, the weighted average cost method is the best choice. Also called the average cost method, it creates an average unit cost that results in a per-unit cost that remains consistent throughout the accounting period. A further consideration would be the effects on the income statement and balance sheet. FIFO results in the inventory reported on the balance being reported at more current costs.

You must also realize that the cost flow assumption is independent of the physical flow of the products. This means you can rotate your company’s inventory (by selling its oldest units first) and yet flow the costs by using LIFO or weighted average. With FIFO, $120 (the first cost) is moved out of inventory and into cost of goods sold. For LIFO, $135 (the last cost) is transferred to expense to gross profit is $45 ($180 less $135).
