How much interest does refinancing save?
Your current loan has about $449,599 of interest left. The new 30-year loan carries about $510,178. On a pure interest basis the difference is $60,579 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.
