Net worth is the value of all the non-financial and financial assets owned by an institutional unit or sector minus the value of all its outstanding liabilities .

Net worth can apply to companies , individuals , governments or economic sectors such as the sector of financial corporations or to entire countries .
The United States dollar ( sign : $ ; code : USD ; also abbreviated US $ and referred to as the dollar , U.S. dollar , or American dollar ) is the official currency of the United States and its territories per the Coinage Act of 1792 . One dollar is divided into 100 cents ( Symbol : ¢ ) or 1000 mills ( for accounting purposes and for taxing . Symbol : ₥ ) . The Coinage Act of 1792 created a decimal currency by creating the following coins : tenth dollar , one-twentieth dollar , one-hundredth dollar . In addition the act created the dollar , half dollar , and quarter dollar coins . All of these coins are still minted in 2020 . In addition , several forms of paper money were introduced by Congress over the years . The latest of these , the Federal Reserve Note , was authorized by the Federal Reserve Act of 1913 , while all existing U.S. currency remains legal tender . Issuance of the previous form of the currency ( U.S. notes ) was discontinued in January 1971 . As a result , currently circulating paper money consists primarily of Federal Reserve Notes that are denominated in United States dollars ( 12 U.S.C . § 418 ) . Since the suspension in 1971 of convertibility of paper U.S. currency into any precious metal , the U.S. dollar is de facto fiat money .
