LIFO is an abbreviation for the phrase (Last in, First out). It is a method of calculating the cost of goods sold (COGS) by using the price of the newest inventory
An inventory is the cost of a purchased product with the intention of reselling.
Consider the inventories arranged from oldest to newest as follows;
1. 3 units that cost $5 each
2. 17 units that cost $6 each
Cost of goods sold can be expressed as;
Cost of goods sold=Number of units sold×cost per unit
where;
Number of units sold=15 units
cost per unit=price of oldest inventory=$5
replacing in the expression above;
Cost of goods sold=(15×5)=$75
Cost of goods sold=$75
