Monthly payment on $400,000 by rate and term
Principal and interest on the $320,000 borrowed after a 20% deposit of $80,000. The rate is the single biggest lever, which is why it is worth shopping.

How the deposit changes it
| Down payment | Loan | P&I | PMI | PMI ends |
|---|---|---|---|---|

| 10% ($40,000) | $360,000 | $2,275.44 | $165.00 | month 109 |
| 20% ($80,000) | $320,000 | $2,022.62 | — | not charged |

What $400,000 costs over the life of the loan
At 6.5% over 30 years on a $320,000 loan, the interest alone comes to $408,141 — on top of the amount borrowed. Shortening the term is the single biggest lever on that number:
| Term | Monthly (P&I) | Total interest | Interest saved |
|---|---|---|---|
| 30 years | $2,023 | $408,141 | — |
| 20 years | $2,386 | $252,601 | $155,539 |
| 15 years | $2,788 | $181,758 | $226,382 |
Paying it off over 15 years instead of 30 costs $765 more a month and saves $226,382 in interest.
What one percentage point of rate is worth here
On a $320,000 loan, going from 6.5% to 7.5% adds $215 a month — and $77,353 across the full term. At this size, a rate quote worth shopping for is worth more than most of the fees people negotiate instead.
The income a lender would look for
Lenders commonly cap housing costs at 28% of gross monthly income. On the full payment of $2,539 — principal, interest, tax, insurance — that implies roughly $108,827 a year before tax. It is a rule of thumb, not an underwriting decision: your other debts, credit score and deposit all move it. See what that salary looks like after tax.
