ACCT 1A Lecture Notes - Lecture 4: Financial Statement, Weighted Arithmetic Mean
Document Summary
When the fifo method is used, the order of costs in and out of inventory is identical for both the perpetual and the periodic inventory systems. Therefore the cost of ending inventory and cost of sales will be the same under both systems. When a periodic inventory system is used, the cost of ending inventory and cost. The weighted average cost per unit is calculated by dividing the cost of goods of sales are computed at the end of the accounting period available for sale by the total units available for sale. Beginning inventory (carried over from prior period) + purchases for the period (accumulated in an inventory account) Cost of sales (measured at every sale, based on perpetual record) = ending inventory (perpetual record updated at every sale) + purchases for the period (accumulated in a purchases account) = cost of goods available for sale. Ending inventory (measured at end of period, based on physical count)
