Definition
The term “rate of interest” refers to the amount charged by a lender to a borrower for the use of assets. It is expressed as a percentage of the principal—the amount loaned. Interest rates often affect economic activity, the cost of borrowing, and the yield on investments. Central banks, such as the Federal Reserve in the United States, play a significant role in setting benchmark interest rates to control inflation and stabilize the economy.
Examples
-
Home Loan: If you take out a home loan of $200,000 at an annual interest rate of 4%, the cost of borrowing will be 4% of $200,000 per year, which equals $8,000 annually.
-
Savings Account: If you deposit $10,000 in a savings account that offers an interest rate of 2% per annum, you will earn $200 in interest by the end of the year.
-
Corporate Bond: A company issues a bond with a face value of $1,000 and an interest rate (coupon rate) of 5%. Investors who buy the bond will receive 5% of the $1,000 annually, which amounts to $50.
