So far, this method is the same as specific identification because we only have one batch of bats to draw from. 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.
- First-in, first-out (FIFO) assumes that the first goods purchased are the first ones sold.
- Notice that the goods available for sale are “allocated” to ending inventory and cost of goods sold.
- In a perpetual inventory system, a subsidiary ledger is kept for every inventory item.
- As purchases and sales are made, costs are assigned to the goods using the chosen cost flow assumption.
To demonstrate the calculations when purchases and sales occur continuously throughout the accounting period, let’s review a more comprehensive example. Choosing among weighted average cost, FIFO, or LIFO can have a significant impact on a business’ balance sheet and income statement. Businesses would select any method based on the nature of the business, the industry in which the business is operating, and market conditions. Decisions such as selecting an inventory accounting method can help businesses make key decisions in relation to pricing of products, purchasing of goods, and the nature of their production lines. Inventory costing remains a critical component in managing a business’ finances.
The second requirement involves assigning the most appropriate cost to this quantity of inventory. In Chapter 5 the journal entries to record the sale of merchandise were introduced. Chapter 5 showed how the dollar value included in these journal entries is determined.
The Impact of Beginning Inventory
The less inventory you keep on hand, the closer your average cost of inventory will be to the current price of inventory. Below is a graph depicting the actual price of inventory vs the computed average cost. Using information from the preceding comprehensive example, the effects of each cost flow assumption on net income and ending inventory are shown in Figure 6.14. Businesses would use the FIFO method because it better reflects current market prices. This is achieved by valuing the outstanding inventory at the cost of the most recent purchases. The FIFO method can help ensure that the inventory is not overstated or understated.
It’s called a moving average because we are always recalculating it. In the periodic system, we took total cost for the year and divided it by total units (for each individual item). Here, in the perpetual system, we have to recalculate the weighted average every time we purchase more of the product.
The weighted-average cost flow assumption is a costing method that is used to assign costs to inventory and the cost of goods sold. Under this approach, the cost of goods available for sale is divided by the number of units produced in the period to arrive at an average cost per unit. This amount is then assigned to the units sold in the period and the units remaining in stock. This method is only used when the periodic inventory system is in place.
As discussed in Chapter 5, any discrepancies identified by the physical inventory count are adjusted for as shrinkage. Businesses would use the weighted average cost method because it is the simplest of the three accounting methods. The inventory cost flow assumption states that the cost of an inventory item changes from when it is acquired or built and when it is sold. Because of this cost differential, management needs a formal system for assigning costs to inventory as they transition to sellable goods.
- Inventory represents all the finished goods or materials used in production that a company has possession of.
- COGS can then be determined by combining the ending inventory cost, beginning inventory cost, and the purchases throughout the period.
- The periodic inventory system requires a physical inventory count at the end of the period.
In terms of its effects on the balance sheet and income statement, LIFO has the opposite effect of FIFO. Thus, inventories are realistically valued on the firm’s balance sheet. These results are logical, given the relationship between ending inventories and gross margin. We deliberately constructed this example to reflect rising prices. This is because, in today’s economy, rising prices are more common than falling prices. With NetSuite, you go live in a predictable timeframe — smart, stepped implementations begin with sales and span the entire customer lifecycle, so there’s continuity from sales to services to support.
The Tax Treatment of Inventories and the Economic and Budgetary Impact of LIFO Repeal
LIFO better matches current costs with revenue and provides a hedge against inflation. Businesses would use the LIFO method to help them better match their current costs with their revenue. This is particularly useful in industries where there are frequent changes in the cost of inventory. This is achieved because the LIFO method assumes that the most recent inventory items are sold first. The average cost flow assumption assumes that all goods of a certain type are interchangeable and only differ in purchase price. The purchase price differentials are attributed to external factors, including inflation, supply, or demand.
Understanding WACC
Under FIFO, the business assumes that the first inventory unit purchased is the first to be sold. The $30 cost of the first inventory unit is deducted against the revenue produced ($40) to net a taxable income of $10. When the business sells a second unit, the business would then deduct a cost of $31; upon selling a third unit, it would deduct a cost of $32. The COGS and Inventory calculations in the perpetual system are the same as in the periodic system, except you need to adjust the average unit cost in real time for each purchase and sale. This is why good accounting software is ideal to use the perpetual system because maintaining perpetual records manually requires a lot of work. As before, we need to account for the cost of goods available for sale (5 books having a total cost of $440).
FIFO, LIFO, and WAC Example
When prices decline, we expect the average cost to be higher than the actual price. A higher average cost would result in higher COGS, lower net income, and lower income taxes. While this is good because taxes are lower, it might not look good in the income statement. When market prices rise, the average cost is lower than the actual price. This difference has several implications—lower average cost would mean lower cost of goods sold, higher net income, and higher income taxes.
The weighted average cost assumption is popular in practice because it is easy to calculate. It is also suitable when inventory is held in common storage facilities — for example, when several crude oil shipments are stored in one large holding tank. To calculate a weighted average, the total cost of all purchases of a particular inventory type is divided by the number of units purchased. Let’s assume that Wexel’s Widgets Inc. utilizes the average cost flow assumption when assigning costs to inventory items. 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.
This technique requires minimal labor, is much cheaper than other inventory cost methods to apply, and, in theory, is less likely to manipulate income. The last‐in, first‐out (LIFO) method assumes the last units purchased are the first to be sold. This method usually produces different results depending on whether the company uses a periodic or perpetual system. The weighted average cost per unit multiplied by the number of units remaining in inventory determines the ending value of inventory. Subtracting this amount from the cost of goods available for sale equals the cost of goods sold. The above examples show that a business’s taxable income in a year differs depending on the inventory valuation method used and the direction of prices.

Financial Accounting
For both individuals and corporations, taxable income differs from—and is less than—gross income. For the IRS, it generally takes its revenues and subtracts its total costs from that year (such as wages, raw materials, interest, and certain state and local taxes). Whether you use accounting software to track inventory or only count inventory by hand with a periodic inventory system, your choice in cost flow assumption has a bottom-line impact on your business. Average cost method is a simple inventory valuation method, especially for businesses with large volumes of similar inventory items. Instead of tracking each individual item throughout the period, the weighted average can be applied across all similar items at the end of the period. First, calculate the total cost of purchases made during the entire period.
