Interest rate. Interest rate is the percentage of the face value of a bond or the balance in a deposit account that you receive as income on your investment. If you multiply the interest rate by the face value or balance, you find the annual amount you receive. For example, if you buy a bond with a face value of $1,000 with a 6% interest rate, you'll receive $60 a year. Similarly, the percentage of principal you pay for the use of borrowed money is the loan's interest rate.
Interest rates are the cost of borrowing money. Interest rates are normally expressed as a % of the total borrowed, e.g for a 30 year mortgage, a bank may charge 5% interest per year. Interest rates also show the return received on saving money in bank or from an asset like government bond.
