Marigold Corp. had a beginning inventory of 110 units of Product RST at a cost of $7 per unit. During the year, purchases were:
Feb. 20 660 units at $8
Aug. 12 430 units at $10
May 5 530 units at $9
Dec. 8 110 units at $11
Marigold uses a periodic inventory system. Sales totaled 1,560 units.
What are the ending inventory and cost of goods sold in FIFO LIFO AVERAGE-COST.
First let us compute the ending inventory balance unit
Ending inventory = Opening + Purchase - Sales
= (110) + (660 + 430 + 530 + 110) - (1560)
= 280 units
1) Now let us compute inventory amount and cost of goods sold under FIFO method
First in fist out means - all the inventory from the beginning gets consumed first and the ending balance basically comes from last purchased units. Last purchased batch are 110 units @ 11. So the balance of 170 units (280 - 110) comes from May 5th batch of 530 units purchased at 9 per unit.
Hence ending inventory cost = 110*11 + 170*9
= 1,210 + 1,530
Ending inventory of 280 units under FIFO method = $ 2,740
Cost of goods sold units = Opening + Purchase - ending
= 110*7 + (660*8 + 430*10 + 530*9 + 110*11) - 2,740
= 770 + 5280 + 4300 + 4770 + 1210 - 2740
CGS under FIFO = 3,310
2) Ending inventory and CGS under LIFO method
Under LIFO the opening units and early putrchases will remain in the closing balance as later purchases are consumed early. Hence the inventory of 280 units will comprise of 110 units @7 from opening balance and 170 units from Feb 20 purchase of units @ 8.
Hence ending inventory cost = 110*7 + 170*8
= 770 + 1,360
= 2,130
Ending inventory of 280 units under LIFO method = $ 2,130
Cost of goods sold units = Opening + Purchase - ending
= 110*7 + (660*8 + 430*10 + 530*9 + 110*11) - 2,130
= 6050 - 2130
CGS under LIFO = 3,920
3) Inventory and CGS under Average cost method
Need to compute weighted average cost per unit
110*7 = 770
660*8 = 5,280
430*10 = 4,300
530*9 = 4,770
110*11 = 1210
Total cost = 16,330
Total units = 1,840
Average cost = 8.875 per unit
Ending inventory = 280 units * 8.875
Ending inventory under average cost methods = $ 2,485
Cost of goods sold units = Opening + Purchase - ending
= 110*7 + (660*8 + 430*10 + 530*9 + 110*11) - 2,485
= 6050 - 2,485
Cost of goods sold under average inventory method = 3,565
