1. What is Weighted Average Inventory?

The weighted average inventory method calculates the average cost of inventory items by considering both the cost and quantity of each item. This method provides a more accurate representation of inventory value than a simple average.

2. How Does the Calculator Work?

The calculator uses the weighted average formula:

\[ \text{Weighted Average} = \frac{\sum (\text{Cost} \times \text{Quantity})}{\text{Total Quantity}} \]

Where:

Cost — Individual item cost in dollars
Quantity — Number of units for each item
Total Quantity — Sum of all quantities

Explanation: The formula calculates the average cost per unit by weighting each cost by its corresponding quantity.

3. Importance of Weighted Average Calculation

Details: Accurate weighted average calculation is crucial for inventory valuation, cost accounting, financial reporting, and making informed business decisions about pricing and inventory management.

4. Using the Calculator

Tips: Enter costs separated by commas in the first field and corresponding quantities separated by commas in the second field. Ensure both lists have the same number of values.
