Interest
Interest is what you pay to borrow money β or what someone pays you to borrow money from you. When you take out a loan from a bank, you have to pay a set amount of money (like, say, 3% per year) for the privilege of borrowing that money β thatβs interest. Equally, when you buy a bond, you are effectively lending money to a company or government and, as such, are paid interest each year by the company or government in order to compensate you for lending it your money.
