Cost per Unit

$10
$12
$14
Units Sold - 250
Step 1 - Apply FIFO Order
Units sold come from earliest purchases first
100 units @ $10
150 units @ $12
Step 2 - Calculate COGS | FIFO
100 × $10 = $1,000
150 × $12 = $1,800
COGS = $2,800
Step 3 - Calculate Ending Inventory
Remaining inventory
50 units @ $12 = $600
150 units @ $14 = $2,100
Ending Inventory = $2,700
