weighted average cost method
The weighted average method is an inventory costing method that assigns average costs to each piece of inventory when it is sold during the year. Retailers and other businesses that keep and sell inventory must keep track of the cost of inventory on hand as well as the cost of inventory that was sold.hen unit of inventory is sold, the weighted average method of costing inventory takes the average cost of all inventories currently available. This average price is then assigned to the item sold. Since inventory prices fluctuate, the weighted average cost will also change. Think about it this way.
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.hen using the weighted average method, divide the cost of goods available for sale by the number of units available for sale, which yields the weighted-average cost per unit.
