What is a bank interest rate and why does it matter?

• A. The fee charged for withdrawing money from an ATM.
• B. The rate at which your money earns interest; higher rates mean more growth for savers.
• C. The minimum balance required to open an account.
• D. The number of digits in your account number.

Answer: (B)

Bank interest rate is the percentage the bank uses to calculate how much your saved money earns over time. The higher the rate, the more money your savings grow, especially when interest is earned on previously earned interest. For example, saving $100 at 2% earns about $2 after a year, while at 5% it earns about $5. Over several years, that difference compounds and leads to a noticeably larger balance. This shows why the rate matters for reaching savings goals. It’s not about fees for withdrawing money, minimum balances, or your account number.
