Yes. There is never a fee for making prepayments or paying your loan off early.
To pay off your loan or to see what your payoff amount is for a given date, Sign In to your Prosper account. You will see a line titled “Remaining balance”, which shows the entire amount due on your loan as of today. To see what your payoff amount is for a future date or to schedule a payment, simply select the “Pay off loan” link and choose the date you’d like to pay your loan off. The “Payoff amount” button will display the balance on your loan on the selected date. To schedule a payment select “Make an additional payment”.
