Definition of Interest Rate
The interest rate is like that charming friend who always charges you a little extra for their services. It represents the amount a lender charges a borrower, expressed as a percentage of the principal—the initial sum of money that was loaned. 🏦 When it comes to loans, interest rates are typically noted on an annual basis and referred to as the annual percentage rate (APR). For savings accounts or certificates of deposit (CDs), it indicates the interest earned. Remember, the landlord of money demands rent!
