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

  1. 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.

  2. 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.

  3. 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.

Frequently Asked Questions (FAQs)

Q1: How is the rate of interest determined?

  • A1: Interest rates are determined by a variety of factors, including the policies of central banks, market demand and supply for credit, inflation expectations, and the creditworthiness of the borrower.

Q2: What is the difference between nominal and real interest rates?

  • A2: The nominal interest rate is the rate before adjusting for inflation, while the real interest rate is the nominal rate minus the inflation rate.

Q3: How do changes in interest rates affect the economy?

  • A3: Increases in interest rates can reduce consumer spending and investment, leading to slower economic growth. Conversely, lower interest rates can stimulate spending and investment, boosting economic activity.

Q4: Why do different loans have different interest rates?

  • A4: Different loans have different rates based on the risk associated with the borrower, the length of the loan term, and whether the interest rate is fixed or variable.

Q5: How can borrowers lower their interest rates?

  • A5: Borrowers can lower their interest rates by improving their credit scores, opting for shorter loan terms, or refinancing when rates are lower.
