Monthly payment on $500,000 by interest rate
Principal and interest only. Every quarter point matters: compare quotes from several lenders on the same day.
| Interest rate | 30-year payment | 30-year total interest | 15-year payment | 15-year total interest |
|---|---|---|---|---|
| 5.00% | $2,684 | $466,279 | $3,954 | $211,714 |
| 5.50% | $2,839 | $522,020 | $4,085 | $235,375 |
| 6.00% | $2,998 | $579,191 | $4,219 | $259,471 |
| 6.50% | $3,160 | $637,722 | $4,356 | $283,997 |
| 7.00% | $3,327 | $697,544 | $4,494 | $308,945 |
| 7.50% | $3,496 | $758,586 | $4,635 | $334,311 |

30-year vs 15-year
At 6.5% for 30 years you pay $3,160 a month and $637,722 in interest over the life of the loan. A 15-year loan usually comes with a lower rate (about 5.9% here): the payment rises to $4,192, but total interest falls to $254,617, saving $383,105.
Your full monthly housing cost
Lenders look at the whole payment, not just the loan. Buying a $625,000 home with 20% down (a $500,000 loan), a 1% property tax and $1,800 a year of insurance adds about $671 a month, for a total of about $3,831. Property tax varies a lot by state:
| State | Property tax rate | Tax per month | Total monthly payment |
|---|---|---|---|
| Texas | 1.4% | $729 | $4,040 |
| California | 0.7% | $365 | $3,675 |
| Florida | 0.78% | $406 | $3,717 |
| New York | 1.3% | $677 | $3,987 |
| Illinois | 1.88% | $979 | $4,290 |
| New Jersey | 1.88% | $979 | $4,290 |
| Colorado | 0.5% | $260 | $3,571 |
| Arizona | 0.48% | $250 | $3,560 |
Income needed for a $500,000 mortgage
Under the common 28% rule, your total housing payment should be no more than 28% of gross monthly income. A payment of about $3,831 works out to an income of about $164,193 a year ($13,683 a month). Lenders also cap all debts, including car and student loans, at around 36–43% of income, so existing debt raises the income you need.
Down payment and home price
The same loan amount lets you buy a different home price depending on your down payment. Below 20% down, conventional loans add private mortgage insurance (PMI) until you reach 20% equity.
| Down payment | Home price | Down payment amount |
|---|---|---|
| 20% | $625,000 | $125,000 |
| 10% | $555,556 | $55,556 |
| 5% | $526,316 | $26,316 |
| 3.5% | $518,135 | $18,135 |
How the balance goes down
Early payments are mostly interest. In the first year you pay $32,335 in interest and only $5,589 off the balance. Paying an extra $100 a month would clear the loan 2 years and 7 months sooner and save $65,822 in interest.
| After | Remaining balance | Paid off |
|---|---|---|
| 1 year | $494,411 | 1% |
| 5 years | $468,055 | 6% |
| 10 years | $423,881 | 15% |
| 15 years | $362,796 | 27% |
| 20 years | $278,326 | 44% |
| 25 years | $161,521 | 68% |
