## 10 3 Calculate the Cost of Goods Sold and Ending Inventory Using the Perpetual Method Principles of Accounting, Volume 1: Financial Accounting

The \$87.50 (the average cost at the time of the sale) is credited to Inventory and is debited to Cost of Goods Sold. The balance in the Inventory account will be \$262.50 (3 books at an average cost of \$87.50). In a moving average system, a new average is determined at the time of each purchase. Then, fifty are bought (bringing the total to sixty) with a cost of \$15 each or \$750 (bringing total cost up to \$120 + \$750 or \$870). In a weighted (or periodic) averaging system, the average for the year is not determined until financial statements are to be produced.

• The cost of goods sold will be calculated by deducting the ending balance.
• In these cases, inventories are small enough that they are easy to manage using manual counts.
• The second sale of 180 units consisted of 20 units at \$21 per unit and 160 units at \$27 per unit for a total second-sale cost of \$4,740.
• One of the main differences between these two types of inventory systems involves the companies that use them.
• This means the cost of its December 31 inventory using periodic LIFO will be \$31 (1 unit at \$11 plus 2 units at \$10).

It is far more sophisticated than the periodic system of inventory management. A purchase return or allowance under perpetual inventory systems updates Merchandise Inventory for any decreased cost. Under periodic inventory systems, a temporary account, Purchase Returns and Allowances, is updated.

Let’s calculate the value of ending inventory using the data from the first example using the periodic LIFO technique. So out of the 14 units sold on January 6, we assign a value of \$700 each to five units with the remainder of 9 units valued at the cost of the next most recent batch (\$600 each). Second, we need to record the quantity and cost of inventory that is sold using the LIFO basis.

Under a periodic inventory system, Purchases will be updated, while Merchandise Inventory will remain unchanged until the company counts and verifies its inventory balance. This count and verification typically occur at the end of the annual accounting period, which is often on December 31 of the year. The Merchandise Inventory account balance is reported on the balance sheet while the Purchases account is reported on the Income Statement when using the periodic inventory method. The Cost of Goods Sold is reported on the Income Statement under the perpetual inventory method.

## Different between Periodic and Perpetual

The company uses a periodic inventory system to account for sales and purchases of inventory. Cameron Ltd. is an electronic retailer company that uses a tracking system to identify every single item in its inventory. The following table illustrates the company’s purchases and sales of LCD screens during the month of April 2017.

• The Cost of Goods Sold is reported on the Income Statement under the perpetual inventory method.
• The perpetual inventory system gives real-time updates and keeps a constant flow of inventory information available for decision-makers.
• The cost of goods sold, inventory, and gross margin shown in Figure 10.15 were determined from the previously-stated data, particular to perpetual FIFO costing.
• When using the perpetual system, the Inventory account is constantly (or perpetually) changing.
• The bad news is the periodic method does do things just a little differently.
• The software you introduce into the workflow will make it easier for you to update and maintain your inventory.

Changes in inventory are accurate (as long as there is no theft or damage to any goods) and can be easily accessed immediately. The information collected digitally is sent to central databases in real-time. Not only must an adjustment to Merchandise Inventory occur at the end of a period, but closure of temporary merchandising accounts to prepare them for the next period is required. Temporary accounts requiring closure are Sales, Sales Discounts, Sales Returns and Allowances, and Cost of Goods Sold. Sales will close with the temporary credit balance accounts to Income Summary. Generally Accepted Accounting Principles (GAAP) do not state a required inventory system, but the periodic inventory system uses a Purchases account to meet the requirements for recognition under GAAP.

On November 18, the cost of seventy units bought on July 6 is also transferred. That leaves thirty units at \$11 each (\$330) plus the December 16 purchase of fifty units at \$15 each or \$750. To illustrate, note that two bathtubs were sold on September 9 by the Mayberry Home Improvement Store.

## Specific Identification

When applying a weighted average system, this single average for the entire period is the basis for both the ending inventory and cost of goods sold to be reported in the financial statements. Beginning merchandise inventory had a balance before adjustment of \$3,150. https://business-accounting.net/ The inventory at period end should be \$7,872, requiring an entry to increase merchandise inventory by \$4,722. Journal entries are not shown, but the following calculations provide the information that would be used in recording the necessary journal entries.

## Comparison of All Four Methods, Perpetual

This formula only uses to make assumptions and calculate the quantity of inventory being sold. To calculate the valuation of goods sold, it will be a problem when the cost we spend changes over time. We will use the valuation methods such as FIFO, LIFO, and Weighted average. Under the https://quick-bookkeeping.net/ periodic system, new inventory purchases will be recorded into the inventory account after receiving. The cost of goods sold will be calculated by deducting the ending balance. When a sales return occurs, perpetual inventory systems require recognition of the inventory’s condition.

Once those units were sold, there remained 30 more units of beginning inventory. At the time of the second sale of 180 units, the FIFO assumption directs the company to cost out the last 30 units of the beginning inventory, plus 150 of the units that had been purchased for \$27. Thus, after two sales, there remained 75 units of inventory that had cost the company \$27 each. The last transaction was an additional purchase of 210 units for \$33 per unit. Ending inventory was made up of 75 units at \$27 each, and 210 units at \$33 each, for a total FIFO perpetual ending inventory value of \$8,955.
