The periodic inventory system is a method of inventory valuation where physical counts of inventory are performed at specific intervals. This approach calculates the cost of goods sold at the end of each accounting period rather than tracking it continuously.

The calculator uses the periodic inventory formula:

Where:

• Beginning Inventory — Inventory count at the start of the period
• Purchases — Additional inventory acquired during the period
• Sales — Inventory sold during the period

Explanation: This formula provides the ending inventory value by accounting for all inventory movements during a specific period.
