Understanding Average Cost Method for Inventory

Calculating ending inventory and COGS under average cost method depends on the inventory system. Now imagine that this same company sold 50 units during this same accounting period. The cost of goods sold (COGS) would be recorded as 50 units sold x $587.50 average cost, or $29,375.

This method calculates the per-unit cost using a weighted average for the cost of goods sold and the inventory. For example, businesses that adopt average cost method need to continue to use this method for future accounting periods. This principle is in place for the ease of financial statement users so that figures on the financials can be compared year over year.

Inventory Carrying Cost Formula

You’ll see that the actual price at this time is $170 and yet the average cost is only $90. We still have to pay $170 per unit to suppliers even though our costing is at $90. The main benefit of the average-cost method is its simplicity, particularly for companies that deal with large volumes of very similar items. Rather than tracking each item and its individual cost, these figures can be averaged. In this article, we’ll explore how to calculate WAC, when to use it, how it compares with other inventory tracking methods, and how it could be advantageous to your business. One of the ways to value your inventory is by applying the Weighted Average Cost Method ( also known as “Inventory Weighted Average”), which is one of the four most common inventory valuation methods.

Sky-high inflation and supply chain interruptions are making inventory costs change like never before. The weighted average cost per unit accounting method can help you keep track of costs, which can impact your prices and save you time and money on administrative tasks. Use it in conjunction with the FIFO and LIFO accounting methods as you operate your store to have a better understanding of your business and drive decisions. If you’re selling multiple SKUs of similar products, the WAC method is a great way to easily determine inventory value and maintain accurate financial statements.

In the final part of our modeling exercise, we’ll calculate the inventory carrying value, i.e. the value recorded on the balance sheet. Suppose a company made the following inventory purchases in the month of July 2022. Since January 13 is our last transaction, let’s assume that no other transactions occurred during the month.

So, simply take $7+$5 and divide the answer by 2, because there were two different batches, and get $6 for the average cost. During the course of the year, the retailer sold a grand total of 200 sunglasses. During the course of the year, the retailer sold 275 of those shoes, meaning they have 125 units still in their inventory. From a government perspective, LIFO is the worst in a high-inflation environment, because today my price is high, but I will report that the last thing that I bought is what I am selling today.

His background is in e-commerce internet marketing and he has helped design the requirements for many features in Dynamic Inventory based on his expertise managing and marketing products online. The ending inventory balance is the beginning balance minus COGS, which results in approximately $1.96 million.

These methods differ from the WAC formula, so understand how they compare before making your decision. The weighted average cost method results in inventory representing https://turbo-tax.org/to-change-without-2020/ a value between the oldest and most recent stock units purchased. The weighted average cost method is one of three ways to value your inventory stock.

The average cost calculation formula is as follows:

The average cost method utilizes a weighted average calculation as a compromise between FIFO and LIFO. In our books, we record the purchases directly to Merchandise Inventory since we’re using the perpetual inventory system. The less inventory you keep on hand, the closer your average cost of inventory will be to the current price of inventory.

• For example, when the batch units are very different, it may not make sense to treat them identically from a cost perspective.
• The weighted average cost method gives you an overall idea about the inventory you have on hand and how much it costs.
• There are many factors to consider when deciding whether it is a good idea to make a change in your method for determining inventory cost.

The HIFO example removes the highest cost inventory first, leaving less value in stock, and the LOFO example removes the lowest cost inventory first, leaving a higher value in stock. Next, the cost of goods sold (COGS) is calculated by multiplying the number of units sold by the weighted average price of $21.76. The process of calculating the average cost method for inventory recognition is a two-step process. Since the perpetual inventory system uses a moving average, the ending balances reported under perpetual inventory can differ from periodic inventory.

How to calculate inventory weighted average cost

During times of inflation,  LIFO results in higher COGS and a lower balance of remaining inventory. Conversely, in WAC, inventory is dispatched based on the weighted average costs of all inventory that the business holds at the time of dispatch. Above, we discussed the accounting and financial statement impacts due to the change in accounting method. But there are additional tax impacts that business leaders should consider as well.

But this doesn’t always happen, and you might not recover those losses and may even end up discontinuing an item. For the remaining inventory cost, take the average cost of $6 and multiply it by the number of sunglasses you have left (50) and get $300. Now, it’s time to calculate the COGS and the remaining inventory valuation. Not only should you be consistently making sure that you have enough inventory so you can fill all your orders, but you should also assign a cost to your stock. This is known as inventory costing — and it is an important part of your business operations for a couple of reasons.
