Worked example
At 6.5% for 30 years, r = 6.5 ÷ 12 ÷ 100 = 0.0054167 and n = 360, so the payment is $3,792.41 a month and you would pay $765,267 in interest over the loan. A 15-year term raises the payment to $5,226.64 but cuts interest to $340,796, saving $424,471.
Buying a $600,000 house vs borrowing $600,000
If $600,000 is the price and you put 20% down, you borrow $480,000: $3,033.93 a month at 6.5% (30 years). Borrowing $600,000 with 20% down means a home price of about $750,000.
Under the traditional 28% guideline (housing cost ≤ 28% of gross income), a $3,792.41 principal-and-interest payment alone suggests a gross income of about $162,532 a year; taxes and insurance push that higher.
