Frequently asked questions
How the maths works
A refinance is worth it when the interest you save exceeds the closing costs. The break-even month is the moment the savings pay for the fees — after that, every month is a gain.
- 1Current loan: amortize the remaining balance at the current rate over the remaining term.
- 2New loan: amortize the balance (plus rolled-in costs and cash-out) at the new rate over the new term.
- 3Monthly savings = current payment − new payment; break-even = closing costs ÷ monthly savings.
- 4Net lifetime savings = (current remaining interest − new total interest) − closing costs.
Figures are illustrative and exclude taxes, insurance, PMI and rate changes. Not financial advice.
Everything you need to know
The break-even is the real test
A lower rate almost always lowers the payment, but closing costs must be repaid from that saving first.
As a rule of thumb, if you cannot break even within about two years, the refinance is usually not worth the paperwork and fees.
Watch the term, not just the rate
Restarting a 30-year term can look cheap monthly while quietly adding years of interest.
Compare the same remaining term first — only then decide whether shortening or extending the term serves your plan.
