  • Monthly Principal and Interest Payment: Uses the amortization formula: ( P times r times (1 + r)^n / ((1 + r)^n – 1) ) where ( P ) is principal, ( r ) is the monthly interest rate, and ( n ) is the number of payments.
  • Monthly Property Tax: Annual property tax rate percentage of the loan amount, divided by 12.
  • Monthly Home Insurance: Annual home insurance cost divided by 12.
