Closing inventory items are considered to be part of opening inventory from the same year.The items purchased or produced last are the first items sold.The last in, first out (LIFO) costing method assumes two things: Once those 10 rings are sold, the cost resets as another round of production begins. Using FIFO, the jeweler would list COGS as $100, regardless of the price it cost at the end of the production cycle. By the end of production, gold rings cost $150 to make. Due to inflation, the cost to make rings increased before production ended. When production started, it cost $100 to make gold rings. However, during price deflation, the opposite may occur.įor example, a jeweler makes 10 gold rings in a month.

This process may result in a lower cost of goods sold compared to the LIFO method. As prices increase, the business’s net income may increase as well. Depending on how those prices impact a business, the business may choose an inventory costing method that best fits its needs.ĭuring inflation, the FIFO method assumes a business’s least expensive products sell first. Deflation causes prices to decrease over time.
