Final answer:
Both personal loans and credit cards can be used for purchases, but they differ in terms of repayment schedules, usage, and grace periods.
Personal loans are typically used for a single large expense and have set repayment terms, whereas credit cards can be used multiple times and often have a grace period for interest accrual.
Step-by-step explanation:
A personal loan is different from a credit card in several ways, but they do not differ in terms of being used only once. Both a personal loan and a credit card are forms of credit used to purchase goods and services.
A personal loan is normally used to finance one large purchase, has a specific repayment schedule, and is different from a credit card, which can be used repeatedly up to its credit limit.
Unlike personal loans, credit cards usually offer a grace period during which you can pay off your balance without incurring interest, while personal loans start accruing interest immediately.
