What a $850,000 mortgage actually costs
Put 20% down — $170,000 — on a $850,000 home and you finance $680,000. At 6.55%, the average 30-year fixed rate as of 2026-07-16, that loan carries a principal-and-interest payment of $4,320/mo. Property taxes, homeowners insurance, and any HOA dues come on top; with a typical 1.1% tax rate and $1,800/yr insurance, the full payment lands near $5,250/mo.
Early in the loan, most of that payment is interest. In month one, roughly $3,712 of the $4,320 payment covers interest and only about $609 pays down the balance. The payment never changes on a fixed-rate loan, but the split shifts steadily toward principal — the chart above shows exactly when the crossover happens for this loan.
The term is the biggest lever on total cost. Over 30 years, a $680,000 loan at 6.55% costs about $875,361 in interest. Compress it to 15 years and the payment rises to $5,942/mo, but lifetime interest drops to $389,603 — a saving of $485,758 at this price.
Can you afford it? The common 28% front-end rule says your full housing payment should stay at or under 28% of gross income. At $5,250/mo, that implies a household income of about $224,983 per year for a $850,000 home with 20% down.
Payment by down payment and term
Principal + interest only, at the current 6.55% average rate — taxes and insurance vary by state, so they're excluded here. Under 20% down, expect PMI on top (the calculator above includes it).
| Down payment | 15-year P&I | 30-year P&I |
|---|---|---|
| 5% ($42,500) | $7,056/mo | $5,131/mo |
| 10% ($85,000) | $6,685/mo | $4,861/mo |
| 20% ($170,000) | $5,942/mo | $4,320/mo |

How we calculate this
Payments use the standard fixed-rate amortization formula at 6.55% — the average 30-year rate as of 2026-07-16 — with taxes and insurance shown only where labeled as assumptions. Figures are planning estimates, not a loan offer — this is not financial advice.
Estimates are for general informational purposes only and do not constitute financial, tax, or lending advice. Actual rates, property taxes, insurance, and payments vary by lender, borrower, and location — the 6.55% rate is a national weekly average, not a quote.
