is finance charge and interest the same thing
In United States law, a finance charge is any fee representing the cost of credit, or the cost of borrowing. It is interest accrued on, and fees charged for, some forms of credit. It includes not only interest but other charges as well, such as financial transaction fees. Details regarding the federal definition of finance charge are found in the Truth-in-Lending Act and Regulation Z, promulgated by the Federal Reserve Board.
