What $400,000 really costs you
At 6.5% over 30 years you would repay about $910,178 in total — the $400,000 you borrowed plus roughly $510,178 in interest. That interest is about 128% of the loan itself.
The same loan over 15 years costs $3,484 a month, which is $956 more, but total interest drops to around $227,197. That's a saving of roughly $282,981 for taking the shorter term.
Income needed for a $400,000 mortgage
Lenders generally want your total housing cost to stay under 28% of gross monthly income. A $2,528 payment therefore points to an income in the region of $108,355 a year — before adding property tax, insurance and your other monthly debts, which the 36% total-debt rule also caps. The affordability calculator works this out precisely for your situation.
