Private student loan consolidation interest rates are variable, based on either the LIBOR (London Interbank Offered Rate) or the Prime rate, plus a margin for borrower and/or co-signer credit.
Origination fees can range between 1% and 5% depending upon your individual credit or the credit of a co-signer. Any fees that associated with the loan are capitalized (added to the loan) typically at the time repayment begins, which increases the amount borrowed but avoids any out-of-pocket expenses at loan closing.
