The cost of goods sold using weighted-average cost under Periodic inventory is $42,429
Before calculating the cost of goods sold, first we have to determine the weighted average cost per unit.
For this following formula should be used:
= (Opening units × cost per unit + purchased units × cost per unit) ÷ (opening units + purchased units)
= (2,000 units × $8 + 5,000 units × $10) ÷ (2,000 units + 5,000 units)
= ($16,000 + $50,000) ÷ (7,000 units)
= $66,000 ÷ 7,000 units
= $9.428
Now the cost of goods sold using weighted-average cost is
= Number of units sold × average cost per unit
= 4,500 units × $9.428
= $42,429
Hence, we conclude that the cost of goods sold using weighted-average cost under Periodic inventory is $42,429.
