Example

  • $400,000 home, $80,000 down, 6.5%, 30 years → ≈ $2,022.62/month; total ≈ $728,142.36
  • $400,000 home, $80k down, 6%, 30 years → Monthly ≈ $1,918.56; total paid ≈ $690,682.20

Formula

Loan = price − down payment, then monthly = L × r × (1+r)n ÷ ((1+r)n − 1). A bigger down payment cuts both the monthly payment and the total interest. This covers principal and interest only — property tax, insurance and PMI are extra.
