Inventory Costing

INVENTORY COSTING METHODS

Inventory costing methods are used to value inventory that was sold during an accounting period and amounts remaining on hand at the end of the period. The methods that will be covered are FIFO (First-In, First-Out), LIFO (Last-In, First-Out), and Weighted Average. RISING PRICES

Example: During a normal accounting period costs of inventory will usually rise. As costs rise the profit provided by each sale becomes smaller. The general picture of FIFO, LIFO, and Average Costs during a period of rising costs is depicted below.
