How Much Is the Monthly Payment on a $500,000 Mortgage?
At 6.5% over 30 years, the principal and interest on a $500,000 mortgage comes to about $3,160 per month. With property tax and insurance included, the realistic total is closer to $3,900 to $4,200.
That is the number that matters. Lenders quote principal and interest; your bank account sees the full figure.

What the total payment includes
| Component | Typical monthly cost | Notes |
|---|---|---|
| Principal & interest | $3,160 | At 6.5% over 30 years |
| Property tax | $350–$1,000+ | The biggest source of variation between states |
| Homeowners insurance | $150–$350 | More in storm, flood, or wildfire areas |
| PMI (if under 20% down) | $200–$400 | Removable at 20% equity |
Early on, the split is lopsided: your first payment puts about $452 toward the balance and $2,708 toward interest. The amortization schedule calculator shows how that shifts month by month.
15-year versus 30-year
| Term | Monthly payment | Total interest | Saved vs 30-year |
|---|---|---|---|
| 30 years | $3,160 | $637,000 | — |
| 20 years | $3,728 | $395,000 | $242,000 |
| 15 years | $4,356 | $284,000 | $353,000 |
The 15-year costs $1,196 more each month and saves roughly $353,000 in interest. Whether that trade is worth it depends on how stable your income is, what other debt you carry, and what else that $1,196 could be doing. There is no single right answer — it is a genuine trade-off between guaranteed savings and monthly flexibility.
What income does this require?
Using the standard rule that housing should stay at or below 28% of gross monthly income, a $4,000 total payment implies about $14,300 a month, or roughly $171,000 a year.
Add a car payment or student loans and you need more, because lenders also cap total debt payments at around 36% of gross income.
Worth repeating: these are lending limits, not comfort limits. Being approved for a $4,000 monthly payment does not mean it will feel manageable, particularly if your income varies or you have no emergency fund yet.
The upfront and ongoing costs people forget
| Cost | Amount | When |
|---|---|---|
| Down payment (20%) | $100,000 | At closing |
| Closing costs (2–5%) | $10,000–$25,000 | At closing |
| Maintenance (1%/year) | ~$420/month | Ongoing, unpredictable |
