FIFO works like how you maintain your fridge at home. After you have bought some groceries, you tend to place what you just bought at the back of the fridge in order to finish off the older food before it spoils.
In other words, under FIFO, the oldest goods are sold first and the newest goods are sold last.
As a formula it would look like this
Unit Cost per batch = (Cost/Quantity) for each batch
where
Cost of Goods Sold = (Unit Cost x Quantity) for each batch
