The Life Periodic Inventory Method is a process used by businesses to calculate the value of their inventory on hand at any given time. It involves taking an inventory count of all items in a company’s possession and then drawing up calculations of their costs, selling prices, and projected profits. This method takes into account the whole life span of the product, from conception to its inevitable end-of-life phase, thus providing a comprehensive view of inventory value over time. By using this method, companies can more efficiently monitor their investments, improve profitability, and remain competitive in their respective markets.
