What is Interest Rate? - Interest rate is the amount charged by lenders to borrowers for the use of money, expressed as a percentage of the principal, or original amount borrowed; it can also be described alternatively as the cost to borrow money. For instance, an 8% interest rate for borrowing $100 a year will obligate a person to pay $108 at year-end. As can be seen in this brief example, the interest rate directly affects the total interest paid on any loan.
