FAQ
Is it worth refinancing $500,000 from 6.50% to 7.50%?
At these numbers it is marginal: the saving is -$218 per month against about $11,500 of closing costs, so break-even is never. Over 7 years the net result is -$29,837.
How much interest does refinancing save?
Your current loan has about $561,999 of interest left. The new 30-year loan carries about $758,586. On a pure interest basis the difference is $196,587 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 $85 per month in savings on this balance, which shortens the break-even window.
