What Is the Retail Inventory Method?
The Retail Inventory Method estimates inventory cost by
➛ Using the retail (selling) price of goods
➛ Applying a cost-to-retail ratio
➛ Estimating ending inventory without a full physical count
It is an estimation method, not an exact valuation.
Why Retailers Use This Method
Retailers prefer this method because it
➛ Saves time and cost
➛ Is useful when dealing with large volumes of inventory
➛ Helps estimate inventory between physical counts
➛ Works well for businesses with consistent markups
Common users

Step 1 - Calculate Cost-to-Retail Ratio
Cost-to-Retail Ratio =
80,000
---------
120,000
---------
120,000
= 66.67%
Step 2 - Calculate Ending Inventory at Retail
120,000 − 75,000 = 45,000
Step 3 - Estimate Ending Inventory at Cost
45,000 × 66.67% = $30,000
Step 4 - Estimate COGS
80,000 − 30,000 = $50,000
Impact on Financial Statements
Income Statement
➛ COGS is estimated
➛ Profit figures are approximate
Balance Sheet
➛ Inventory value is estimated
➛ Suitable for internal reporting
Limitations of the Retail Inventory Method
➛ Not as accurate as FIFO, LIFO, or Weighted Average
➛ Depends heavily on consistent markups
➛ Not suitable when prices fluctuate widely
➛ Not ideal for external financial reporting
