When a company uses the weighted-average method and prices are rising, its cost of goods sold is less than that obtained under LIFO, but more than that obtained under FIFO. Inventory is not as understated as under LIFO, but it is not as up-to-date as under FIFO. A company can manipulate income under the weighted-average costing method by buying or failing to buy goods near year-end. However, the averaging process reduces the effects of buying or not buying.

If weighted average periodic is the easiest of all the methods, the weighted average perpetual is the hardest. It is not that the method is hard, it is just annoying because you must calculate a new weighted average cost for each sale, based on the units available for sale at that time. When doing weighted average perpetual, do not separate the purchases and sales. Without the weighted average cost method, you wouldn’t be able to manage inventory without assigning different costs to your incoming and stored inventory. WAC allows you to store your inventory without assigning separate costs to all identical items. Thus, your inventory management process becomes very simple and doesn’t require you to keep a tab of the pricing for all purchases.

Standard costing is when companies assign the expected costs of material, labor and overhead to inventory, rather than the actual costs.

It should be understood that, although LIFO matches the most recent costs with sales on the income statement, the flow of costs does not necessarily have to match the flow of the physical units. The gas and petroleum industries utilize the weighted average costing method for inventory purposes. The extraction, collection and storage of liquid fuels and related products makes it necessary for those involved in both the manufacture and sale of these products to use this inventory method. The inability to differentiate one batch of fuel from another when they are stored together makes weighted average costing the proper solution for keeping track of inventory.

Weighted average costing makes it simpler to account for these types of items. Now let’s change the larger volume example so that you still bought 100 of each unit but sold 250. To calculate LIFO COGS, you start with the last purchase and work backwards. To cover the 250 units in sales, you’d need 100 of unit C, then 100 of unit B, then 50 of unit A. Your LIFO COGS would be 100 unit C x $7.50 + 100 unit B x $8 + 50 unit A x $7 for a total of $1,900.

Therefore ending inventory consists of 50 units from beginning inventory and 50 units from the October 10 purchase.

The USD 509 cost of goods sold is an expense on the income statement, and the USD 181 ending inventory is a current asset on the balance sheet. The specific identification costing method attaches cost to an identifiable unit of inventory. The method does not involve any assumptions about the flow of the costs as in the other inventory costing methods. Conceptually, the method matches the cost to the physical flow of the inventory and eliminates the emphasis on the timing of the cost determination. Therefore, periodic and perpetual inventory procedures produce the same results for the specific identification method. The Weighted-Average Method of inventory costing is a means of costing ending inventory using a weighted-average unit cost.
