What does interest rate mean in banking?

Interest rate is the amount that is charged for a loan or purchase made on credit, typically expressed as an annual percentage of the loan or credit balance. The interest rate represents the cost to the borrower for taking out the loan or making a purchase on credit, and is the rate of return for the lender or creditor.

Most loans, mortgages, credit card balances, or purchases made on credit use simple interest, in which the interest rate applies only to the outstanding balance, without adding in or compounding the interest.

For example, if a loan of $1,000 carries an annual interest rate of 10%, then the borrower pays the lender $1,000 x 10% = $100 in interest during each year of the loan. As the balance is paid down, the amount of interest due goes down accordingly.

For credit cards, the interest rate may be stated as an APR (annual percentage rate) to indicate the amount of interest charged if the credit balance were carried for a full year.

interest rate vs. APR

Interest rate and APR (annual percentage rate) are terms that are easy to confuse, as they are both annual percentage rates related to how much a loan will cost on top of the principal amount being borrowed.

The interest rate is the advertised rate of interest used in calculating the interest expense on a loan. The interest expense is the remaining balance (or principal) multiplied by the annual rate.

APR includes the interest expense as well as other charges or fees involved in getting the loan.
