Frequently asked questions
- Should I refinance federal loans?
- Only if you are sure you will not need IDR, PSLF, or other federal discharges. A private refinance cannot be undone.
- Does this pull lender rates?
- No. Enter the offer you already have. Nothing is sent to a marketplace.
- Fees?
- Some lenders advertise $0 origination. If there is a fee, it is added to the new balance for payment math.
- Variable rate?
- Use the start rate. This page does not model rate caps.
