A branch of
accounting that observes and calculates the actual
costs of a company's operations. Internal managers, rather than
auditors, use cost accounting most of the time to identify aspects of their company where costs can be cut. For example, a manager may enlist a cost accountant to determine the most expensive aspects of his/her business that is, where the
money goes. The accountant may make a detailed report so that the manager may make decisions based upon it. Because cost accounting is primarily internal, it need not conform to the
Generally Accepted Accounting Principles. It is also called managerial or management accounting. See also:
