example of weighted average cost method
When 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.In this calculation, the cost of goods available for sale is the sum of beginning inventory and net purchases.he total of all purchased or beginning inventory units is 450 (150 beginning inventory + 300 purchased). The weighted average cost per unit is therefore $257.78 ($116,000 Ã· 450 units.).
