How FIFO Works - Step by Step

Example Inventory Purchases

Date
Jan 1
Jan 10
Jan 20

Units
100
200
150

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
