1. What Is Average Inventory Level?

Average Inventory Level represents the mid-period stock value calculated as the mean of beginning and ending inventory balances over a specific period. It provides a more accurate picture of inventory investment than single point measurements.

The calculator uses the Average Inventory formula:

\[ Avg\ Inv = \frac{Beg + End}{2} \]

Where:

\( Avg\ Inv \) — Average Inventory (units or currency)
\( Beg \) — Beginning Inventory value
\( End \) — Ending Inventory value

Explanation: This simple average method smooths out fluctuations and provides a representative value for inventory management analysis throughout the period.
