In a perpetual average cost system a new weighted-average unit cost is calculated each time additional units are purchased.

"Average" represents the mean expense of production items from the sale time below the perpetual method. This marginal cost is compounded by the numbers of distribution units, deducted from the stock in the possession and debited to the Expense of Items Sold balance.
