Frequently asked questions

How much do extra mortgage payments save?

Every extra dollar of principal skips all the future interest that dollar would have accrued. On a 30-year loan, even $200 extra a month can save tens of thousands in interest and cut years off the term. Enter your loan above to see your exact savings.

Do biweekly payments really pay off a mortgage faster?

Yes. Paying half your monthly amount every two weeks results in 26 half-payments — equal to 13 monthly payments per year instead of 12. That one extra payment annually goes entirely to principal and typically shaves 4–6 years off a 30-year loan.

Is it better to pay extra or refinance?

They solve different problems. Refinancing lowers your rate; extra payments lower your balance faster at your current rate. If your rate is well above today's, refinancing first and then paying extra compounds the savings.
