What $800,000 of mortgage really costs

A $800,000 mortgage is high-cost-metro territory — or a lot of house elsewhere. It stays under the baseline conforming loan limit ($806,500 in 2025), so standard conforming rates apply. At this size, an eighth of a point is real money: $66 a month.

The full monthly bill is more than principal and interest. If this loan is 80% of the home's price ($1,000,000 home), national-average property tax (1.1%/yr) adds about $917/month and average insurance ($2,341/yr) another $195 — bringing the realistic total to roughly $6,168/month. Under the classic 28% housing ratio, that suggests around $264,355 of household income. Local taxes change this a lot — see the state-by-state comparison.

Frequently asked questions

How much is the monthly payment on a $800,000 mortgage?

At 6.5% on a 30-year fixed loan, principal and interest run $5,056.54 per month. With typical property taxes and insurance on top (assuming the loan is 80% of the home's price), the full monthly cost is roughly $6,168. On a 15-year term at the same rate the payment is $6,968.86. The table above shows every half-point from 5% to 8%.

How much income do I need for a $800,000 mortgage?

Using the standard 28% housing-ratio guideline and the full payment estimate above, you'd want roughly $264,355 of gross annual income ($22,030 per month). Less existing debt, a bigger down payment, or a lower rate all reduce that requirement — work your exact numbers in our home affordability calculator.

How much interest does a $800,000 mortgage cost over 30 years?

At 6.5%, total interest over a full 30-year schedule is about $1,020,356 — 128% of the amount borrowed. A 15-year term cuts that to about $454,395, and extra payments can remove years without changing the required payment.
