Commitment Fee A fee lenders charge their borrowers for unused credit or credit that has been promised at a specified future date. Investopedia Says: A commitment fee is different from interest; although, the two are often confused. A lender charges a borrower a commitment fee to keep a line of credit open, or to guarantee a loan at a certain future date even though the credit is not being used at that particular time.
