Worked example
At 6.5% for 30 years, r = 6.5 ÷ 12 ÷ 100 = 0.0054167 and n = 360, so the payment is $2,686.29 a month and you would pay $542,064 in interest over the loan. A 15-year term raises the payment to $3,702.21 but cuts interest to $241,397, saving $300,667.
Buying a $425,000 house vs borrowing $425,000
If $425,000 is the price and you put 20% down, you borrow $340,000: $2,149.03 a month at 6.5% (30 years). Borrowing $425,000 with 20% down means a home price of about $531,250.
Under the traditional 28% guideline (housing cost ≤ 28% of gross income), a $2,686.29 principal-and-interest payment alone suggests a gross income of about $115,127 a year; taxes and insurance push that higher.
Rates in the tables are a range for comparison, not current market quotes. Payments are principal and interest only unless stated.
