Jan 1: Beginning Inventory 100 $18.00 $1,800.00
Mar 4: Purchase 400 $19.00 $7,600.00
Apr 1: Sold (50)
In a perpetual inventory system, what is the average cost per unit after the March 4 purchase?
A. $18.00
B. $18.80
C. $18.20
Explanation: The average cost per unit is determined by dividing the total cost of $9,400 by the 500 units purchased ($9,400 / 500 units = $18.80, the average cost per unit).

murli | Any purchase, the average cost is the same! Don't get confused about the date. |
Joel1980 | Perpetual Inventory must equal Weighted Average Cost. |
azramirza | From where does 9400 come? Oh, it's (BI) 1800 + (Purchase) 7600 |
prtwf | wow... where does the LOS or question mention WAC = Perp Inventory method... this material needs some work... |
CJPerugini | @Joel1980 that is not true. A perpetual system means that inventory and COGS are being updated at every transaction instead of once a period. Perpetual systems can follow LIFO, FIFO, or Weighted Avg Cost. |
Inaganti6 | Thanks CJPerugini. I don't know how some people pontificate their opinions like they're facts. Ridiculous. |
