The monthly payment on a $1 million mortgage ranges from roughly $4,800 to $7,000, depending on the interest rate and loan term you choose.
The exact amount depends on three things: how much you borrow, what interest rate you lock in, and how many years you have to repay it. A $1 million loan at 7% interest over 30 years costs about $6,655 per month in principal and interest alone. At 6%, the same loan costs $5,995 per month. At 8%, it jumps to $7,338. The difference between a 6% and 8% rate is nearly $1,400 a month—$16,800 a year.
But principal and interest is only part of what you actually pay. Your monthly mortgage statement also includes property taxes, homeowners insurance, and possibly mortgage insurance or HOA fees. These vary by location and property type. In a high-tax state like New Jersey or California, property taxes alone can add $800 to $1,500 per month to a $1 million home. In a lower-tax state, they might add $300 to $600. Insurance typically runs $150 to $400 per month for a home at that price point.
Key Takeaways
- A $1 million mortgage at 7% interest over 30 years costs $6,655 per month in principal and interest, before taxes and insurance.
- Interest rates matter enormously: a 1% difference changes your monthly payment by roughly $600 to $700 on a $1 million loan.
- Property taxes and insurance can add $500 to $2,000 per month depending on your state and the home's location.
- Shorter loan terms (15 years instead of 30) roughly double your monthly payment but cut total interest paid nearly in half.
How the interest rate moves your payment
Interest rate changes hit hard on large loans because you are paying interest on a large balance. On a $1 million mortgage over 30 years, each percentage point of interest adds roughly $600 to your monthly payment. A borrower at 5% pays $5,368 per month. At 6%, that becomes $5,995. At 7%, it is $6,655. At 8%, it reaches $7,338.
The reason the impact is so large is that interest compounds over 360 monthly payments. On a $1 million loan at 5%, you pay roughly $933,000 in total interest over 30 years. At 8%, you pay roughly $1,640,000 in total interest. That extra 3% costs you more than $700,000 over the life of the loan.
Interest rates change based on market conditions, the Federal Reserve's decisions, and your own credit profile and down payment size. A borrower with a 760 credit score and 20% down might lock in a rate 0.5% lower than someone with a 700 score and 10% down. Shopping with multiple lenders can reveal rate differences of 0.25% to 0.75%, which translates to $150 to $450 per month.
Loan term: 15 years versus 30 years
A 15-year mortgage on $1 million at 7% costs about $9,911 per month in principal and interest. A 30-year mortgage on the same loan at the same rate costs $6,655 per month. The 15-year loan is $3,256 more per month—but you own the home free and clear 15 years sooner, and you pay roughly $785,000 less in total interest.
The trade-off is straightforward: higher monthly payment in exchange for lower total interest and faster ownership. A 15-year loan makes sense if your income is stable and you want to minimize the total cost of borrowing. A 30-year loan makes sense if you want the lowest possible monthly payment, or if you think you could earn a higher return by investing the difference rather than paying down the mortgage faster.
Some borrowers choose a middle ground: a 20-year loan. At 7% interest on $1 million, a 20-year mortgage costs about $7,750 per month. It splits the difference between monthly payment and total interest paid.
What happens when you add taxes, insurance, and other costs
Your actual monthly mortgage payment—the number on your statement—includes more than just principal and interest. It typically includes property taxes and homeowners insurance, and sometimes mortgage insurance or HOA fees.
Property taxes vary wildly by state and county. In Cook County, Illinois, the effective property tax rate is roughly 0.8% of home value per year. On a $1 million home, that is about $8,000 per year, or $667 per month. In Nassau County, New York, the rate is roughly 1.1%, which is about $11,000 per year or $917 per month. In Texas, it is roughly 1.6%, which is about $16,000 per year or $1,333 per month. In some California counties, it is closer to 0.6%, which is about $6,000 per year or $500 per month.
Homeowners insurance on a $1 million home typically costs $150 to $400 per month, depending on the home's age, location, and whether it is in a flood or wildfire zone. Older homes or homes in high-risk areas cost more to insure.
If you put down less than 20%, your lender will require private mortgage insurance (PMI), which protects the lender if you default. On a $1 million loan with 10% down, PMI might add $400 to $800 per month. Once your equity reaches 20%, you can request that PMI be removed.
How down payment size affects the monthly payment
The larger your down payment, the smaller the loan amount, and the smaller your monthly payment. A $1 million home with 20% down ($200,000) means you borrow $800,000. A $1 million home with 10% down ($100,000) means you borrow $900,000. The difference in monthly payment is roughly $600 to $700 at current rates.
Down payment also affects whether you pay PMI. With 20% or more down, PMI is not required. With less than 20% down, it is mandatory. This is a significant cost that disappears once you reach 20% equity, either through down payment or through paying down the principal over time.
Some borrowers make a smaller down payment and invest the difference, betting that investment returns will exceed the mortgage interest rate. Others make a larger down payment to avoid PMI and reduce monthly costs. Both approaches have merit depending on your financial situation and risk tolerance.

| 7.5% | $6,994 | $10,968 | $1,318,000 |
| 8.0% | $7,338 | $11,322 | $1,641,000 |
These numbers show principal and interest only. Add property taxes, insurance, and PMI (if applicable) to get your true monthly housing cost. A borrower in a high-tax state might add $1,500 to $2,000 per month. A borrower in a lower-tax state might add $700 to $1,000 per month.
How to estimate your actual payment
Start with a mortgage calculator and plug in the loan amount, interest rate, and term. That gives you principal and interest. Then add your estimated property taxes (check your county assessor's website or ask a local real estate agent), homeowners insurance (get quotes from at least two insurers), and PMI if your down payment is less than 20%.
Your lender will provide a Loan Estimate within three business days of your process. This document shows the principal and interest payment, property taxes, insurance, PMI, HOA fees, and other costs. It is the most accurate picture of what you will actually pay each month. The Loan Estimate is required by federal law and is free.
Keep in mind that property taxes and insurance can increase over time. Property taxes typically rise 2% to 4% per year as home values climb or tax rates change. Insurance can jump 5% to 15% per year depending on claims history and market conditions. Budget for these increases when deciding whether a $1 million mortgage fits your finances.
Frequently Asked Questions
What income do I need to afford a $1 million mortgage?
Most lenders use a debt-to-income ratio of 43%, meaning your total monthly debt payments (including the mortgage) should not exceed 43% of your gross monthly income. On a $1 million mortgage at 7% with taxes and insurance, your total monthly payment might be $8,500 to $9,500. To stay within 43%, you would need a gross monthly income of roughly $20,000 to $22,000, or about $240,000 to $264,000 per year. This varies by lender and your other debts.
Can I get a better rate if I pay points?
Yes. A mortgage point is 1% of the loan amount. On a $1 million loan, one point costs $10,000 upfront and typically lowers your interest rate by 0.25%. Paying points makes sense if you plan to stay in the home long enough to recoup the upfront cost through lower monthly payments. On a $1 million loan, one point saves roughly $150 to $175 per month, so you break even in about 57 to 67 months (roughly 5 to 6 years).
What happens to my payment if interest rates drop after I lock in?
Your payment stays the same unless you refinance. Refinancing means taking out a new loan to pay off the old one. You pay closing costs again (typically 2% to 5% of the loan amount), so refinancing only makes sense if the new rate is low enough to save you money over time. If rates drop 0.5% or more, refinancing is often worth considering.
Does the payment change if I make extra principal payments?
Your required monthly payment does not change, but paying extra principal reduces the total interest you pay and shortens the loan term. An extra $500 per month on a $1 million mortgage at 7% over 30 years cuts roughly 7 years off the loan and saves about $300,000 in interest. You can make extra payments without penalty on most mortgages.
What if I want to pay off the mortgage early?
Most mortgages have no prepayment penalty, meaning you can pay off the entire balance whenever you want without extra fees. Paying off early saves you interest but reduces your liquidity. Some borrowers prefer to keep the mortgage and invest extra money instead, betting that investment returns will exceed the mortgage rate.
