Frequently asked questions
Extra payments go directly to principal, reducing your balance faster. That lowers the interest you pay each month and can shorten your loan term significantly.
It depends on your rate and goals. Use this calculator to see how much interest you save and how many years you cut off the loan. Compare that to other uses for the money (e.g. investing).
Most conventional mortgages in the US do not have prepayment penalties. Check your loan documents to confirm. This calculator assumes no prepayment penalty.
