Grace Period

On a credit card, the grace period runs from the close of a statement to its due date — at least 21 days under federal rules — and it is what lets you use a card without paying interest. New purchases accrue nothing during it.

The catch is that it is conditional. The grace period only exists if you paid the previous statement balance in full. Carry any balance forward and it collapses: interest starts accruing on new purchases the day they post, and it does not come back until you pay the full balance again. Cash advances and balance transfers typically get no grace period at all.

Student loans use the term differently. Federal loans generally give six months after you leave school before payments begin. Subsidized loans do not accrue interest during that window; unsubsidized loans do, and that interest is usually capitalized into the balance when repayment starts.

Mortgages and auto loans usually allow around fifteen days past the due date before a late fee applies, which is separate again from credit reporting — a payment is typically not reported as late until it is 30 days past due.

Insurance policies have their own version: a window after a missed premium during which coverage continues and the policy can be reinstated before it lapses.
