Why do banks charge interest on loans?
Show answer & explanation
Answer: Compensates risk and time value
Compensates risk and time value ✓ — Correct! Interest compensates lenders for three things: (1) the time value of money—money available now is worth more than money in the future, (2) inflation risk—the money repaid might buy less due to inflation, and (3) default risk—the borrower might not repay. Higher-risk loans (no collateral, poor credit) charge higher interest to compensate for greater risk.
To punish people who need money — Wrong. Interest isn't punishment—it's compensation for risk and opportunity cost. Banks must attract deposits by paying interest to savers, then charge higher interest to borrowers to cover those costs plus operating expenses and default risk. Without interest income, banks couldn't afford to make loans at all, limiting economic growth.
Government requires interest — Wrong. Governments don't require banks to charge interest—market forces and business economics drive interest rates. Interest exists because money has time value and lending involves risk. Governments regulate maximum interest rates (usury laws) in some cases, but don't mandate that interest must be charged.
