Perkins Loans carry a fixed interest rate of 5% for the duration of the ten-year repayment period. The Perkins Loan Program has a nine-month grace period, so that borrowers begin repayment in the tenth month upon graduating, falling below half-time status, or withdrawing from their college or university.
