Worked example
At 6.5% for 30 years, r = 6.5 ÷ 12 ÷ 100 = 0.0054167 and n = 360, so the payment is $2,054.22 a month and you would pay $414,520 in interest over the loan. A 15-year term raises the payment to $2,831.10 but cuts interest to $184,598, saving $229,922.
Buying a $325,000 house vs borrowing $325,000
If $325,000 is the price and you put 20% down, you borrow $260,000: $1,643.38 a month at 6.5% (30 years). Borrowing $325,000 with 20% down means a home price of about $406,250.
Under the traditional 28% guideline (housing cost ≤ 28% of gross income), a $2,054.22 principal-and-interest payment alone suggests a gross income of about $88,038 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.
