interest

Payment for the use of money over time. You earn interest by lending your money. If you borrow money, interest is the amount you pay to borrow the money. The rate of interest can be fixed or variable. It is usually calculated as a percentage of the amount lent or borrowed. For example on a $10,000 car loan that has an interest rate of 10%, you would pay $1000 interest in the first year.
