Frequently asked questions
What is refinance break-even?
It is the approximate month when cumulative payment savings offset refinance costs.
Why can a new 30-year term cost more?
Restarting a longer term can extend interest even when the rate and payment are lower.
Should I refinance based only on payment?
No. Compare total interest, costs, time in the home, and risks—not just payment.
