$650,000 loan: monthly payment by rate

| 5.5% | $3,690.63 | $5,311.04 | $678,626 |
| 6% | $3,897.08 | $5,485.07 | $752,948 |
| 6.5% | $4,108.44 | $5,662.20 | $829,039 |
| 7% | $4,324.47 | $5,842.38 | $906,808 |

Worked example
At 6.5% for 30 years, r = 6.5 ÷ 12 ÷ 100 = 0.0054167 and n = 360, so the payment is $4,108.44 a month and you would pay $829,039 in interest over the loan. A 15-year term raises the payment to $5,662.20 but cuts interest to $369,196, saving $459,844.
Buying a $650,000 house vs borrowing $650,000
If $650,000 is the price and you put 20% down, you borrow $520,000: $3,286.75 a month at 6.5% (30 years). Borrowing $650,000 with 20% down means a home price of about $812,500.
Under the traditional 28% guideline (housing cost ≤ 28% of gross income), a $4,108.44 principal-and-interest payment alone suggests a gross income of about $176,076 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.
