Interest Rate

The amount charged by a lender to a borrower for the use of assets, expressed as a percentage of the principal. It also refers to the earning rate for deposits held in a financial institution.

Definition of Interest Rate

An interest rate is the percentage of a loan or deposit balance that is paid to the lender or depositor as interest. It is typically expressed as an annual percentage of the principal. For loans, it represents the cost of borrowing money, while for deposits, it signifies the earnings on the deposited funds.

Examples of Interest Rates

  1. Personal Loan Interest Rate: If a borrower takes out a $10,000 personal loan with an annual interest rate of 5%, they will owe an additional $500 in interest over a year.

  2. Mortgage Interest Rate: For a $200,000 mortgage with a 4% annual interest rate, the annual interest cost to the borrower would be $8,000.

  3. Savings Account Interest Rate: A savings account with a balance of $5,000 and an annual interest rate of 1% will earn the depositor $50 in interest over one year.

2. How are interest rates calculated?

Interest rates can be calculated in various ways, but the formula for simple interest is:

3. What is the difference between fixed and variable interest rates?

  • Fixed Interest Rate: The rate remains constant throughout the loan or deposit term.
