Quick answer: $5,291 – $6,124/mo
The monthly payment on a $800,000 house is roughly $5,291 to $6,124 depending on your down payment, interest rate, taxes, insurance, and PMI.
Estimates use a 30-year fixed loan, 7.0% interest rate, 1.2% annual property tax, 0.35% annual homeowners insurance, and PMI when down payment is below 20%. Actual payments vary by location, lender, credit profile, taxes, insurance, and loan terms.

Over 30 years, you'll pay $892,857 in interest - more than 1.4x your loan amount.

In year 1, 87% of your payment goes to interest and only 13% reduces your balance.
At this rate, it takes until year 21 before more than half your payment builds equity.
On your $640,000 loan, you'll pay $892,857 in interest - 1.4x what you originally borrowed.
Switching to a 15-year term would cut your interest in half - but raise your monthly payment.

If the payment feels high - a lower home price or larger down payment will move the needle more than a slightly better rate.
If you're close to 20% down - getting there eliminates PMI and meaningfully reduces your monthly cost.
If you're comparing loan terms - a 15-year mortgage costs more monthly but saves significantly on total interest.
| Down Payment | Loan Amount | P&I + Taxes + Ins | PMI | Est. Total Monthly |
|---|---|---|---|---|
| 10% ($80,000) | $720,000 | $5,824/mo | $300/mo | $6,124/mo |
| 20% ($160,000) | $640,000 | $5,291/mo | None | $5,291/mo |
| 30% ($240,000) | $560,000 | $4,759/mo | None | $4,759/mo |
With a 20% down payment ($160,000) and a 30-year fixed mortgage at 6.8%, your estimated monthly payment would be about $4,172 for principal and interest. When you add average property taxes and home insurance, the total monthly payment is typically around $5,000 to $5,300.
Following the 28% rule, which states your housing costs shouldn't exceed 28% of your gross monthly income, you would need an annual household income of approximately $215,000 to $230,000 to comfortably afford an $800,000 home with 20% down.
Putting 20% down ($160,000) allows you to avoid Private Mortgage Insurance (PMI), which can save you hundreds of dollars each month. It also lowers your loan amount to $640,000, reducing your monthly payments and total interest paid over the life of the loan.
