What $1 million of mortgage really costs
A $1 million mortgage is high-cost-metro territory — or a lot of house elsewhere. Note that $1,000,000 exceeds the baseline conforming loan limit ($806,500 for 2025; higher in designated high-cost counties), which makes this a jumbo loan for most buyers — jumbo rates and underwriting differ from conforming loans. At this size, an eighth of a point is real money: $82 a month.
The full monthly bill is more than principal and interest. If this loan is 80%
of the home's price ($1,250,000 home), national-average property tax (1.1%/yr)
adds about $1,146/month and average insurance ($2,341/yr) another
$195 — bringing the realistic total to roughly $7,662/month.
Under the classic 28% housing ratio, that suggests around $328,354 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 $1 million mortgage?
At 6.5% on a 30-year fixed loan, principal and interest run $6,320.68 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 $7,662. On a 15-year term at the same rate the payment is $8,711.07. The table above shows every half-point from 5% to 8%.
How much income do I need for a $1 million mortgage?
Using the standard 28% housing-ratio guideline and the full payment estimate above, you'd want roughly $328,354 of gross annual income ($27,363 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 $1 million mortgage cost over 30 years?
At 6.5%, total interest over a full 30-year schedule is about $1,275,445 — 128% of the amount borrowed. A 15-year term cuts that to about $567,993, and extra payments can remove years without changing the required payment.
Assumptions & sources: Payments computed with the standard
amortization formula (engine verified against published examples — see the site
repository). The 6.5% figure is illustrative, not an offer;
tax/insurance estimates use national averages (1.1% effective property tax,
$2,341/yr insurance — Bankrate 2025) and vary widely by location.
