Perpetual Inventory

Definition of 'Perpetual Inventory'


A method of accounting for inventory that records the sale or purchase of inventory in near real-time, through the use of computerized point-of-sale and enterprise asset management systems. Perpetual inventory provides a highly detailed view of changes in inventory and allows real-time reporting of the amount of inventory in stock, hence, accurately reflecting the level of goods on hand.

Investopedia explains 'Perpetual Inventory'


A perpetual inventory system is superior to the older periodic inventory systems because it allows for real-time tracking of sales as well as inventory levels for individual items, helping to prevent stock outs. A perpetual inventory also does not need to be adjusted manually by the company's accountants except to the extent it disagrees with the physical inventory count due to loss, breakage or theft.

Hot Definitions
  1. Market Capitalization

    The total dollar market value of all of a company's outstanding shares. Market capitalization is calculated by multiplying a company's shares outstanding by the current market price of one share. The investment community uses this figure to determine a company's size, as opposed to sales or total asset figures.
  2. Oil Reserves

    An estimate of the amount of crude oil located in a particular economic region. Oil reserves must have the potential of being extracted under current technological constraints. For example, if oil pools are located at unattainable depths, they would not be considered part of the nation's reserves.
  3. Joint Venture - JV

    A business arrangement in which two or more parties agree to pool their resources for the purpose of accomplishing a specific task. This task can be a new project or any other business activity. In a joint venture (JV), each of the participants is responsible for profits, losses and costs associated with it.
  4. Aggregate Risk

    The exposure of a bank, financial institution, or any type of major investor to foreign exchange contracts - both spot and forward - from a single counterparty or client. Aggregate risk in forex may also be defined as the total exposure of an entity to changes or fluctuations in currency rates.
  5. Organic Growth

    The growth rate that a company can achieve by increasing output and enhancing sales. This excludes any profits or growth acquired from takeovers, acquisitions or mergers. Takeovers, acquisitions and mergers do not bring about profits generated within the company, and are therefore not considered organic.
  6. Family Limited Partnership - FLP

    A type of partnership designed to centralize family business or investment accounts. FLPs pool together a family's assets into one single family-owned business partnership that family members own shares of. FLPs are frequently used as an estate tax minimization strategy, as shares in the FLP can be transferred between generations, at lower taxation rates than would be applied to the partnership's holdings.
