FAQ

Is it worth refinancing $600,000 from 6.50% to 7.50%?

At these numbers it is marginal: the saving is -$262 per month against about $13,500 of closing costs, so break-even is never. Over 7 years the net result is -$35,504.

How much interest does refinancing save?

Your current loan has about $674,399 of interest left. The new 30-year loan carries about $910,303. On a pure interest basis the difference is $235,904 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 $102 per month in savings on this balance, which shortens the break-even window.
