LIFO

An inventory valuation method that assumes the last items added to the inventory are the first ones to be sold ("Last In, First Out").

Weighted Average

A calculation that takes into account the different degrees of importance of the numbers in a dataset, making some values count more heavily than others.

Cost Flow Assumption

Accounting methods used to determine the cost of goods sold and ending inventory, such as FIFO (First-In, First-Out) or LIFO (Last-In, First-Out).
