Mortgage payment on a $400K house
$2,653 a month with 20% down at 7.11% — including property tax and insurance. You'd need an income of about $113,700.
On a $400,000 home with $80,000 (20%) down, you borrow $320,000. At 7.11% (30-year fixed, Freddie Mac average for the week of Nov 12, 2026), principal and interest come to $2,153 a month. Adding property tax at the U.S. average of 0.9% ($300) and insurance ($200) gives $2,653. Over 30 years you would pay $454,958 in interest.
Payment by down payment
Putting less than 20% down means a bigger loan and mortgage insurance, so the monthly payment rises:
| Down payment | Cash down | Loan | Principal + interest | PMI / MIP | Tax + insurance | Total / month | Income needed |
|---|---|---|---|---|---|---|---|
| 20% down | $80,000 | $320,000 | $2,153 | $0 | $500 | $2,653 | $113,700 |
| 10% down | $40,000 | $360,000 | $2,422 | $150 | $500 | $3,072 | $131,700 |
| 5% down | $20,000 | $380,000 | $2,556 | $158 | $500 | $3,215 | $137,800 |
| 3.5% down (FHA) | $14,000 | $392,755 | $2,642 | $177 | $500 | $3,319 | $142,300 |
Assumes a 30-year fixed loan at 7.11%, property tax of 0.9% of the home value a year, homeowners insurance of 0.6% a year, PMI of 0.5% of the loan a year when the down payment is under 20%, and FHA mortgage insurance of 0.55% a year plus a 1.75% upfront premium added to the loan. Your rate, taxes and insurance will differ.
