The formula
Loan amount = home price − down payment. Monthly payment = P × r(1+r)ⁿ ÷ ((1+r)ⁿ−1).
The calculator uses the full precision of your inputs and rounds only the values shown on screen. This helps avoid compounding rounding errors.
Worked example
A $400,000 home with $80,000 down at 6.5% for 30 years produces a principal-and-interest payment of about $2,023 per month.
