Perpetual Inventory Calculator

The perpetual inventory system helps businesses track inventory in real-time by continuously updating inventory levels as purchases and sales occur. This calculator simplifies the process of determining the ending inventory using the following basic formula:

Calculation Formula

\[ \text{Ending Inventory} = \text{Beginning Inventory} + \text{Purchases} - \text{Sales} \]

Example Calculation

If you start with 1,000 units, purchase 500 more, and sell 300 units, the ending inventory would be:
\[ \text{Ending Inventory} = 1,000 + 500 - 300 = 1,200 \text{ units} \]

Usage Scenarios

The perpetual inventory system is widely used in businesses with frequent inventory transactions, such as retail stores, where real-time data is crucial for stock management and order planning.
