Answer:
A lender makes money from the interest that is charged every month. If a borrower repays the loan earlier than expected, lenders will not receive the full amount of expected interest. As a result, some lenders charge an early payment fees to make up for the interest they would loose.
However not all lenders do this, so we suggest looking for a loan that gives you the freedom to pay off the loan and get out of debt as soon as possible.
