Mortgage payment on a $750,000 house
About $3,792 a month in principal and interest with 20% down at 6.5%, or roughly $4,792 once tax and insurance are included. Here is the full breakdown.
The short answer
On a $750,000 home with 20% down ($150,000) and a 30-year fixed mortgage at 6.5%, the principal and interest payment is about $3,792 per month.
That figure is only part of the bill. Once you add property tax and homeowners insurance, the realistic monthly cost is closer to $4,792. Over the full 30 years you would pay roughly $765,267 in interest on top of the $600,000 you borrowed.
Monthly payment on $750,000 by interest rate
Rate matters more than almost anything else. These figures assume 20% down, so a loan of $600,000.
| Rate | 30-year | 15-year |
|---|---|---|
| 5.50% | $3,407 | $4,903 |
| 6.00% | $3,597 | $5,063 |
| 6.50% | $3,792 | $5,227 |
| 7.00% | $3,992 | $5,393 |
| 7.50% | $4,195 | $5,562 |
A single percentage point of rate changes the 30-year payment on this loan by roughly $403 a month. That is why shopping several lenders is worth real money.
How the down payment changes it
All rows below use a 30-year fixed at 6.5%.
| Down payment | Loan amount | Monthly P&I |
|---|---|---|
| 3% ($22,500) | $727,500 | $4,598 |
| 5% ($37,500) | $712,500 | $4,503 |
| 10% ($75,000) | $675,000 | $4,266 |
| 20% ($150,000) | $600,000 | $3,792 |
Below 20% down you will normally also pay private mortgage insurance (PMI), commonly $250–$500 a month at this loan size, until you build enough equity to remove it.
What the full monthly cost looks like
- Principal & interest: $3,792
- Property tax (est. 1.1% of value a year): $688
- Home insurance (est. 0.5% a year): $312
- Total estimated monthly: $4,792
Property tax varies enormously by state — well under 0.5% in some places and above 2% in others — so check the actual rate for the county you are buying in before you rely on this number. HOA dues, if the home has them, are on top.
What income do you need for a $750,000 house?
Using the common 28% rule, a $4,792 housing payment implies gross income of about $205,000 a year. Lenders also look at your total debts, so car loans and student loans reduce what you qualify for.

Ways to lower the payment
- Buy down the rate. Paying points upfront cuts the rate; worth it only if you stay long enough to recover the cost.
- Put more down. Reaching 20% removes PMI and shrinks the balance.
- Improve your credit before applying. The gap between a strong and mediocre score is often a half point or more of rate.
- Compare a 15-year term. The payment is higher but total interest drops sharply — see the table above.
