Your full monthly house payment, total interest, and how much extra principal payments save.
How this calculator works
Your total payment combines principal and interest (from the amortization formula), property tax, homeowners insurance, private mortgage insurance (PMI) when you put down less than 20%, and HOA dues. PMI falls off automatically once the balance reaches 78% of the original price. Adding extra principal each month shortens the loan and can save tens of thousands in interest.
