Interest is best described as...

• A. The cost of money that is borrowed, usually a percentage of the borrowed amount.
• B. A one-time fee for creating an account.
• C. The amount of money you save each year.
• D. A measure of a loan's risk.

Answer: (A)

Interest is the price you pay to borrow money. It’s the cost of using someone else’s funds, typically expressed as a percentage of the loan’s principal over a set period. The percentage is the interest rate, and it shows how much extra you’ll owe beyond repaying the original amount. For example, borrowing $1,000 at 5% yearly interest would cost about $50 in interest for one year (not accounting for any compounding). This concept reflects the time value of money and the lender’s compensation for taking on the loan. The other ideas describe different things—an upfront account fee, money saved each year, or a loan’s risk—so they don’t capture what interest really represents.
