FAQ
Is it worth refinancing $400,000 from 7.50% to 6.50%?
Yes by the usual test: the monthly payment drops about $355, closing costs are roughly $9,500, and you break even in about 27 months. Over 7 years the net gain is about $20,292.
How much interest does refinancing save?
Your current loan has about $534,071 of interest left. The new 30-year loan carries about $510,178. On a pure interest basis the difference is $23,893 saved — remember the new loan also restarts the term.
What if rates drop further?
Every extra 0.25% lower on the new rate adds roughly $65 per month in savings on this balance, which shortens the break-even window.
