When does intrest on a direct unsubsidized loan begin to accrue?

Interest on a direct unsubsidized loan begins to accrue as soon as the loan is disbursed. Unlike subsidized loans, where the government covers interest during certain periods, borrowers are responsible for paying the interest on unsubsidized loans from the outset. This means that even while a student is in school, during the grace period, or while in deferment, interest continues to accumulate. Borrowers can choose to pay the interest while in school to avoid it capitalizing (adding to the principal) later.
