What's the PLUS loan interest rate?

For PLUS Loans disbursed on or after July 1, 2006, the interest rate is fixed (at 7.90 for Direct PLUS Loans and 8.50 percent for FFEL PLUS Loans). For PLUS Loans disbursed between July 1, 1998 and June 30, 2006, the interest rate is variable and is determined on July 1 of every year. For 2007-2008, the variable rate for these PLUS Loans (in both the Direct and FFEL programs) is 8.02 percent. Interest is charged on a PLUS Loan from the date of the first disbursement until the loan is paid in full.
