What is a credit card grace period?

• A. The time between the purchase date and due date during which no interest is charged if the balance is paid in full.
• B. A period when penalties are charged for late payments.
• C. The window during which cash advances are interest-free.
• D. The time allowed to dispute a transaction on a card.

Answer: (A)

The idea being tested is how a credit card grace period works. A grace period is the span from when you make a purchase to your due date, during which you won’t be charged interest on new purchases—as long as you pay the full balance by the due date. This is why it’s the best description: it specifies both the time frame and the condition (pay in full) that lets you avoid interest.

Keep in mind there are important details. If you carry a balance from the previous cycle, the grace period often doesn’t apply, and interest can start accruing on new purchases right away. Cash advances and some transfers usually don’t have a grace period and typically accrue interest immediately, sometimes with additional fees. The window for disputing a transaction is separate from this and doesn’t affect whether interest is charged.

So the grace period describes the no-interest window from purchase date to due date, provided you pay in full by the due date.
