The weighted average cost per unit is therefore $257.78 ($116,000 Ã· 450 units.). The ending inventory valuation is $45,112 (175 units Ã $257.78 weighted average cost), while the cost of goods sold valuation is $70,890 (275 units Ã $257.78 weighted average cost).The sum of these two amounts (less a rounding error) equals the $116,000 total actual cost of all purchases and beginning inventory.eighted Average Method Overview. The weighted average method is used to assign the average cost of production to a product. Weighted average costing is commonly used in situations where: 1  Inventory items are so intermingled that it is impossible to assign a specific cost to an individual unit.
The calculation is based on the average cost per unit of inventory for particular accounting period. The following formula is used to calculate Average Cost per Unit under the Weighted Average Method: Average Cost per Unit = (Beginning Inventory + Purchases (in money)) Ã· (Beginning Inventory + Purchases (in units)).or example, you sell books. The weighted average cost is $30.00 USD per book ($4500 USD/150 books according to the formula above used to calculate Average Cost per Unit). So the inventory price $30 USD will be the same for each book bought, the actual price of one book is $27 USD while another book was sold at $32 USD.
