How do the discounts work?

Discounts remove time off your loan. Your monthly payment does not change, but the overall time you pay does. For loans over $20,000, if you take advantage of both discounts, on average you will save:
Almost 3 years on a 20 year loan
Almost 4 years on a 25 year loan
Almost 5 years on a 30 year loan

The 0.25% automatic debit discount is permanent as long as you continue to use the program.

The 1% discount for the first 36 consecutive on time payments is effective after 36 months.
