Definition

The Periodic Inventory Method is an accounting technique used to calculate the cost of inventory that has been sold or moved to production during a specific accounting period. This method involves updating the inventory records at the end of the accounting period by considering the beginning inventory, purchases made during the period, and the ending inventory.

Examples

  1. Retail Store Example: A bookstore uses the periodic inventory method. At the beginning of January, it has $10,000 worth of books in stock. During the month, it purchases books worth $5,000 and ends January with $8,000 worth of books unsold. Thus, the cost of books sold in January is calculated as:

    \[ \text{Cost of Goods Sold (COGS)} = \text{Beginning Inventory} + \text{Purchases} - \text{Ending Inventory} \]

    \[ \text{COGS} = $10,000 + $5,000 - $8,000 = $7,000 \]

  2. Manufacturing Example: A garment manufacturer begins the quarter with $15,000 worth of raw materials. During the quarter, the company purchases $10,000 worth of materials and ends with $5,000 worth. The cost of materials put into production is:

    \[ \text{COGS} = $15,000 + $10,000 - $5,000 = $20,000 \]

Frequently Asked Questions

Q1: How is the periodic inventory method different from the perpetual inventory method?

A1: While the periodic inventory method updates inventory records at the end of an accounting period, the perpetual inventory method continuously updates the records for each sale or purchase transaction.

Q2: What are the advantages of using the periodic inventory method?

A2: The periodic inventory method is simpler and less expensive to implement since it requires fewer operational resources and systems integration compared to the perpetual inventory method.

Q3: What are the limitations of the periodic inventory method?

A3: The primary limitation is the lack of real-time inventory data, which can lead to stockouts, overstocking, and less effective inventory management. It also makes it harder to detect inventory shrinkage and theft.

  • Cost of Goods Sold (COGS): The direct costs attributable to the production of the goods sold by a company, including the cost of the materials and labor directly used in creating the good.
  • Perpetual Inventory Method: An accounting system where inventory and cost of goods sold accounts are continuously updated for each transaction.
  • Inventory Shrinkage: The loss of products between point of manufacture and point of sale. This can be due to theft, damage, loss, or errors.
  • Gross Profit: The difference between revenue from product sales and the cost of goods sold.
