FAQ

Is it worth refinancing $400,000 from 7.00% to 6.50%?

Yes by the usual test: the monthly payment drops about $223, closing costs are roughly $9,500, and you break even in about 43 months. Over 7 years the net gain is about $9,231.

How much interest does refinancing save?

Your current loan has about $491,408 of interest left. The new 30-year loan carries about $510,178. On a pure interest basis the difference is $18,770 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 $65 per month in savings on this balance, which shortens the break-even window.
