Monthly payment on a $100,000 mortgage
The monthly principal and interest payment on a $100,000 mortgage at 6.5% for 30 years is $632.07.
- Over the full 30 years you'd pay $127,544 in interest — $227,544 in total, or $1.28 of interest for every $1 borrowed.
- A 15-year loan at the same rate costs $871.11 a month — $239 more — but cuts total interest to $56,799, saving $70,745.
- Taxes and insurance come on top: using the Mortgage Calculator's defaults (1.1% property tax on a $125,000 home and $1,800 a year of insurance), the full monthly payment is about $896.65.
- On the 30-year schedule, principal first outpaces interest in year 20, and half the loan is repaid by the end of year 22.
- Lenders often cap housing costs at 28% of gross income; keeping principal and interest alone under that line takes about $27,089 a year — more once taxes and insurance are counted.

What this number includes
The $632.07 figure is principal and interest only — the part fixed for the life of a fixed-rate loan. It assumes a $100,000 loan, for example a $125,000 home with 20% down, so no private mortgage insurance applies.
$100,000 is under the conforming loan limit in every U.S. county, so it can be a standard conforming loan eligible for sale to Fannie Mae or Freddie Mac.
