You are always welcome to make extra manual payments to pay down your loan, or pay off your loan in full. There is never a fee for making an additional payment. However, please note that you are only able to pay one due date ahead. In order to do so, that payment must be made on or after the preceding due date.
Additional loan payments will not be applied to payments owed for subsequent months, nor will they postpone the due date of the following monthly installment. Please refer to your Upstart dashboard to see details and the distribution of any additional payments being made.
As a reminder, one time payments do not cancel or modify any scheduled recurring payments.
