FAQ
Is it worth refinancing $400,000 from 6.50% to 7.50%?
At these numbers it is marginal: the saving is -$175 per month against about $9,500 of closing costs, so break-even is never. Over 7 years the net result is -$24,170.
How much interest does refinancing save?
Your current loan has about $449,599 of interest left. The new 30-year loan carries about $606,869. On a pure interest basis the difference is $157,270 more — remember the new loan also restarts the term.
What if rates drop further?
Every extra 0.25% lower on the new rate adds roughly $68 per month in savings on this balance, which shortens the break-even window.
