Borrowing $320,000 (a $400,000 home with 20% down) at 6.5% for 30 years means a monthly payment of about $2,023 and roughly $408,000 in total interest — more than the amount borrowed. At 2.5% inflation, the real lifetime cost of those payments is about $514,000 in today's money rather than the $728,000 nominal total.
On that same $320,000 loan, adding $200 a month to every payment clears the mortgage about 4.5 years early and saves roughly $86,000 in interest.
