The monthly payment on a $1 million mortgage ranges from about $4,800 to $7,000, depending on your interest rate and loan term
The exact amount depends on three things: how much you borrowed, the interest rate you locked in, and whether you chose a 15-year, 20-year, or 30-year repayment period. A $1 million loan at 7% interest over 30 years costs roughly $6,650 per month in principal and interest alone. At 5%, the same loan runs about $5,370 per month. At 8%, it climbs to $7,340.
That monthly figure does not include property taxes, homeowners insurance, or mortgage insurance if your down payment was less than 20%. Those costs vary sharply by location and your specific situation, so the true monthly obligation is usually higher than the base payment.
Key Takeaways
- A $1 million mortgage at 7% interest over 30 years costs approximately $6,650 per month in principal and interest, but this varies with your rate and loan term.
- Shorter loan terms (15 years) mean higher monthly payments but less total interest paid; longer terms (30 years) lower the monthly cost but increase total interest.
- Your actual monthly obligation includes property taxes, homeowners insurance, and possibly mortgage insurance, which can add $1,000 to $3,000 or more depending on location and down payment.
- The interest rate you receive depends on your credit score, down payment size, and current market conditions at the time you lock in your rate.
How the interest rate changes your payment
Interest rate differences that seem small on paper create large differences in your monthly bill. The table below shows how a $1 million mortgage payment shifts across common interest rates, all calculated for a 30-year term:
| Interest Rate | Monthly Payment (Principal + Interest) | Total Interest Paid Over 30 Years |
|---|---|---|
| 4.5% | $5,066 | $823,760 |
| 5.0% | $5,368 | $932,360 |
| 6.0% | $5,996 | $1,158,680 |
| 7.0% | $6,653 | $1,395,080 |
| 8.0% | $7,338 | $1,641,680 |
A single percentage point difference between 6% and 7% adds $657 to your monthly payment. Over the life of the loan, that same point difference costs you an extra $236,400 in interest. This is why locking in the lowest rate available to you matters: even a 0.25% reduction saves tens of thousands of dollars.
How loan term affects what you pay each month
Choosing a 15-year mortgage instead of 30 years cuts your repayment period in half but raises your monthly payment significantly. On a $1 million loan at 7% interest, a 15-year term costs about $8,988 per month, compared to $6,653 for 30 years. That is $2,335 more each month.
The trade-off is that you pay far less interest overall. Over 15 years at 7%, you pay roughly $618,840 in total interest. Over 30 years at the same rate, you pay $1,395,080—more than double. If you can afford the higher monthly payment and want to own the home free and clear sooner, a shorter term saves money in the long run. If monthly cash flow is tight, the 30-year term keeps your payment manageable.
Twenty-year mortgages sit in the middle: monthly payments around $7,750 at 7%, with total interest of about $860,000. Some borrowers choose this as a compromise between affordability and interest savings.
Property taxes, insurance, and mortgage insurance add to your bill
The principal and interest payment is only part of what you owe each month. Most lenders require you to pay property taxes and homeowners insurance as part of your mortgage payment, held in an escrow account. On a $1 million home, property taxes alone can range from $500 to $2,000 or more per month depending on your state and county. Homeowners insurance typically runs $100 to $300 per month for a property of this value.
If your down payment was less than 20%, you will also pay private mortgage insurance (PMI), which protects the lender if you default. PMI on a $1 million loan usually costs between 0.5% and 1.5% of the loan amount annually, or roughly $400 to $1,250 per month. This cost drops off once you reach 20% equity in the home, either through payments or appreciation.
Adding these together, your true monthly obligation could easily be $8,500 to $10,000 or higher, depending on location and your specific situation. This is why lenders look at your debt-to-income ratio: they want to see that your total monthly debt payments (including this mortgage) do not exceed 43% to 50% of your gross monthly income.
How your credit score and down payment affect the rate you receive
The interest rate you may have access to for is not fixed across all borrowers. Lenders price risk based on your credit score and how much money you put down. A borrower with a 760+ credit score and a 30% down payment might lock in 6.5%, while a borrower with a 680 score and 10% down might receive 7.5% for the same loan product at the same time.
That 1% difference on a $1 million mortgage adds up to $657 per month and $236,400 over 30 years. Improving your credit score before applying, saving for a larger down payment, or waiting for rates to drop are all ways to lower the rate you receive. Some borrowers also pay discount points at closing—paying a fee upfront to reduce the interest rate by 0.25% or 0.5%. Whether this makes sense depends on how long you plan to stay in the home.
What happens if you pay extra toward principal
If your monthly budget allows, paying extra toward principal shortens your loan term and cuts total interest dramatically. On a $1 million mortgage at 7% over 30 years, adding just $500 per month to your principal payment reduces the loan term to about 24 years and saves roughly $280,000 in interest.
Some mortgages include a prepayment penalty—a fee charged if you pay off the loan too quickly—but these are rare on conventional mortgages. Check your loan documents to confirm there is no penalty. If you receive a bonus, tax refund, or inheritance, directing even part of it toward principal can have a meaningful impact on the total cost of the loan.
Frequently Asked Questions
Can I get a $1 million mortgage with a lower credit score?
Yes, but you will pay a higher interest rate. Most lenders require a credit score of at least 620 for a conventional mortgage, though 680 or higher is more common for jumbo loans (mortgages over $766,200 in most areas). A lower score might add 0.5% to 1.5% to your rate, which translates to hundreds of dollars more per month.
What is a jumbo mortgage?
A jumbo mortgage is any loan that exceeds the conforming loan limit set by Fannie Mae and Freddie Mac, which is $766,200 in most U.S. counties (higher in some expensive areas). A $1 million mortgage is a jumbo loan. Jumbo loans typically require a larger down payment (20% or more), a higher credit score, and carry a slightly higher interest rate than conforming loans.
How much do I need to earn to may have access to for a $1 million mortgage?
Lenders typically want your total monthly debt payments—including the new mortgage—to be no more than 43% to 50% of your gross monthly income. On a $1 million mortgage at 7% with taxes and insurance, your monthly obligation might be $8,500 to $9,500. This suggests a gross monthly income of roughly $17,000 to $22,000, or $204,000 to $264,000 annually, though this varies by lender and location.
Should I choose a 15-year or 30-year mortgage?
A 15-year mortgage saves you roughly $775,000 in interest but costs about $2,335 more per month. Choose 15 years if you can comfortably afford the higher payment and want to own the home free and clear sooner. Choose 30 years if you need the lower monthly payment or want to invest the difference elsewhere. A 20-year term offers a middle ground.
What if interest rates drop after I lock in my rate?
You can refinance your mortgage to a lower rate, but you will pay closing costs (typically 2% to 5% of the loan amount). Refinancing makes sense if the rate drop is large enough that your monthly savings cover the closing costs within a few years. Use a refinance calculator to compare your current payment against the new payment plus closing costs.
