For example, at 6.50% over 30 years, a $400,000 mortgage costs about $2,528/month. That's about $632/month more than a $300,000 mortgage at the same rate and term - about $127,544 more in total interest paid over the full 30 years. Over the full 30 years you'd pay about $910,178 total - meaning roughly $510,178 of that, or 56% of every payment made, is interest on top of the $400,000 borrowed. Within the $100,000-$1,000,000 range this page series covers, $400,000 sits around the 43th percentile.
To comfortably afford a $400,000 home under the standard 28%-of-income guideline (20% down, 6.50% rate, including estimated property tax and insurance), you'd want a gross household income around $107,398/year. See the full income breakdown for a $400,000 house.

- Interest rate: on this $400,000 loan, a 0.5% rate bump (to 7.00%) adds about $133/month - real money compounded over 30 years.
- Term: switching this $400,000 loan to 15 years raises the payment by about $956/month but cuts total interest dramatically.
- Down payment: a bigger down payment lowers the amount financed and shrinks every number in the table above.
