c) Weighted Average Method

Under this method units are sold at average cost. Average Cost per unit is calculated after each purchase transaction and then this average cost per unit is applied to sold units to calculate the cost of goods sold.

Average Cost per Unit = Cost of Goods Available in Inventory / Number of Units available in inventory

Perpetual Weighted Average
