The Last In, First Out (LIFO) method assumes that customers are buying the newest items in your inventory. Therefore, costs are calculated by dividing the COGS of the newest items in your inventory divided by the number of units purchased. The First In, First Out (FIFO) method assumes that customers are buying the oldest pieces of inventory in stock. FIFO uses the COGS for the items that were purchased first and divides it by the number of units purchased. Therefore, the cost of the oldest items is reported in the company’s financial statements. When the weighted average cost method is no longer useful, that’s when other accounting methods, like FIFO and LIFO, come in handy.

This article will look at the weighted average cost method to value your inventory. Weighted average method is a method of calculating an average that takes into account the relative importance of each item in the dataset. It is calculated by multiplying each item in the dataset by a certain weight, then summing the products and dividing by the total weight. Under the ‘average cost method’, it is assumed that the cost of inventory is based on the average cost of the goods available for sale during the period. In our example, the inventories purchased experienced a price appreciation.

Weighted Average/Average Costing

All three are equally valid, but one thing to keep in mind is that once a business chooses the method, it will need to remain consistent across all financial reports.

Now, for the remaining inventory value, take the 10 remaining hats and assume they all belonged to the first batch.

The result can then be applied to both the cost of goods sold (COGS) and the cost of goods still held in inventory at the end of the period. The U.S however accepts LIFO because it is compliant with the General Accepted Accounting Principles (GAAP). It’s hard to determine if you are going to attain your revenue goals without knowing the worth of your inventory. It’s even harder to make any crucial business decisions without knowing how much your inventory is worth. That same retailer from the first example purchases 30 hats for $5 each (what a steal) at the beginning of the year. “So the WAC would be the total they paid divided by 300 units,” Dr. Ray explains.

What is the formula for weighted average cost method?

Assume that both beginning inventory and beginning inventory cost are known. Each time, purchase costs are added to beginning inventory cost to get cost of current inventory. Similarly, the number of units bought is added to beginning inventory to get current goods available for sale.

In a periodic inventory system, all inventory purchases are initially recorded in the Purchases account, which substitutes for the COGS expense during the period. Under average costing method,the average cost of all similar items in the inventory is computed and used to assign cost to each unit sold. Like FIFO and LIFO methods,  this method can also be used in both perpetual inventory system and periodic inventory system. Inventory weighted average (also known as ‘weighted average cost’) is one of the four most common inventory valuation methods used in ecommerce accounting.

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. However, a low average cost would not affect the amount that we’ll pay to suppliers. Any business that sells products must find an efficient way to deal with inventory.

Method 3: Weighted Average Cost

The weighted average cost method requires a single cost calculation to determine the average value of all items in stock. Since every item is valued at the same amount, there is no need to maintain detailed inventory purchasing records, which means less paperwork to keep track of. The weighted average cost method is the simplest way to track inventory expenses. You don’t need to track which batch an item belongs to or what the original cost was. WAC isn’t the best accounting method to use in every scenario, which is why the FIFO and LIFO accounting methods exist.

The only requirement when choosing a method is that at the end of the period, the sum of COGS and ending inventory equals the cost of goods available. The Pacific Bead Company sells handcrafted beads from local island crafters to retail markets and customers out of its warehouse. From the company’s accounting software, the following is its reporting period information. Together, the COGS and the inventory valuations add up to the actual total cost available for sale. The beginning number of units is 290, which represents the total units purchased in July. This method can also be used to determine the average amount invested in each of a group of securities.

Generally, the FIFO method is widely accepted by most business owners because it reflects the most accurate picture of costs and profitability.
