Retail Inventory Method: Inventory Technique Using the Cost Method of Accounting

The Retail Inventory Method is an inventory technique that estimates the cost of inventory by applying an average percentage of cost to the retail price of merchandise. This method can use either physical inventory counting or a perpetual inventory system.

The Retail Inventory Method is a widely used inventory valuation technique that leverages the cost method of accounting. This method is particularly beneficial for retail businesses as it allows for efficient inventory management and cost estimation.

How the Retail Inventory Method Works

Pooling Merchandise

Retail businesses often deal with various types of merchandise. Under the Retail Inventory Method, similar types of merchandise are pooled together. This pooling is essential for estimating an average percentage of cost to retail price.

Estimation of Cost Percentage

Once the merchandise is pooled, an average percentage of cost to retail price is calculated. This percentage is then applied to the inventory to estimate its cost. The formula is generally:

$$ \text{Cost Percentage} = \left( \frac{\text{Cost of Goods Available for Sale}}{\text{Retail Value of Goods Available for Sale}} \right) \times 100 $$

Application of the Method

Physical Inventory Counting

One approach under this method involves physical inventory counting. This process includes physically counting all inventory on hand and then applying the average cost percentage to estimate the cost.

Book Inventory System (Perpetual Inventory System)

Alternatively, the method can use a perpetual inventory system. This system continuously updates inventory records for purchases and sales, thus providing a real-time estimate of inventory costs.

Types of Retail Inventory Method

• Conventional Retail Method: This method excludes markdowns from the calculation, making it a conservative approach.
• Cost Retail Method: Includes markdowns in the calculation, offering a more comprehensive view.
• LIFO Retail Method (Last-In, First-Out): Assumes that the last items added to the inventory are the first to be sold.
• FIFO Retail Method (First-In, First-Out): Assumes that the first items added to the inventory are the first to be sold.

Historical Context

The Retail Inventory Method originated in the early 20th century as a logical extension of the periodic inventory system. It was developed to address the complexities of inventory management in large retail operations. Over time, it has evolved to accommodate different business needs and accounting standards.

Applicability and Comparisons

Advantages

• Efficiency: Facilitates quick inventory valuation.

• Applicability: More suited for businesses with relatively stable merchandise pricing.

Comparison with Other Methods

• Specific Identification Method: Unlike the Retail Inventory Method, this method assigns specific costs to specific items.
• Weighted Average Cost Method: Uses an average cost for all units, whereas the Retail Inventory Method relies on the cost-to-retail ratio.
• First-In, First-Out (FIFO) Method: Based on the chronological order of inventory acquisition.

Related Terms

• Perpetual Inventory System: An inventory system that continuously updates inventory records.
• Physical Inventory: Actual counting of inventory items.
• Markdown: Reduction in the original selling price of inventory items.
• Cost of Goods Available for Sale: The total cost of inventory that is ready for sale during a period.
