The monthly payment on a $300,000 mortgage depends on three things: your interest rate, your loan term, and your down payment. At today's average rate of around 6.5% on a 30-year loan, a $300,000 mortgage costs $1,896 per month in principal and interest. Your total monthly payment including property tax and homeowners insurance is typically $2,100 to $2,400.
But that number changes significantly depending on your rate and term. Here is a complete breakdown so you know exactly what to expect.
Monthly Payment on $300,000 at Every Interest Rate
The table below shows your exact principal and interest payment on a $300,000 loan at different interest rates for both 30-year and 15-year terms.
| Interest Rate | 30-Year Payment | 15-Year Payment | Total Interest (30yr) |
|---|---|---|---|
| 5.5% | $1,703 | $2,451 | $313,212 |
| 6.0% | $1,799 | $2,532 | $347,514 |
| 6.5% ← avg 2025 | $1,896 | $2,614 | $382,633 |
| 7.0% | $1,996 | $2,697 | $418,527 |

What Is Included in Your Monthly Mortgage Payment?
Most people think the mortgage payment is just the loan repayment. In reality your monthly payment has up to four components, commonly called PITI:
Principal
This is the portion of your payment that pays down the actual loan balance. In the early years of a 30-year mortgage, very little of your payment goes toward principal. On a $300,000 loan at 6.5%, only about $271 of your first payment goes to principal — the rest is interest.
Interest
This is the cost of borrowing the money. Early in your loan the interest portion is highest. On that same $300,000 loan your first payment includes roughly $1,625 in interest. By year 20 the split flips and more goes to principal.
Property Tax
Your lender typically collects property tax monthly and holds it in escrow. The national average property tax rate is about 1.1% of home value per year — on a $300,000 home that is roughly $275 per month added to your payment.
Homeowners Insurance
Also collected in escrow. Average homeowners insurance runs $100 to $200 per month depending on your location and home value.
So your total monthly payment on a $300,000 mortgage at 6.5% is more realistically:
| Component | Monthly Amount |
|---|---|
| Principal & Interest | $1,896 |
| Property Tax (est.) | $275 |
| Homeowners Insurance | $150 |
| Total Monthly Payment | ~$2,321 |
How Down Payment Changes Your Monthly Payment
Your down payment directly affects how much you borrow and therefore your monthly payment. Here is how different down payments on a $350,000 home price affect your monthly cost at 6.5%.
| Home Price | Down Payment | Loan Amount | Monthly P&I |
|---|---|---|---|
| $350,000 | 3.5% — $12,250 | $337,750 | $2,136 |
| $350,000 | 5% — $17,500 | $332,500 | $2,103 |
| $350,000 | 10% — $35,000 | $315,000 | $1,991 |
| $375,000 | 20% — $75,000 | $300,000 | $1,896 |
| $400,000 | 25% — $100,000 | $300,000 | $1,896 |
Can I Afford a $300,000 Mortgage?
Using the 28% rule — the most common affordability guideline — your monthly housing costs should not exceed 28% of your gross monthly income. At a total monthly payment of $2,321, you need a gross monthly income of at least $8,289, which equals an annual salary of approximately $99,500.
However if you have low debt and strong credit you may qualify with a lower income. Lenders use your debt-to-income ratio (DTI) which includes all monthly debt payments, not just your mortgage.

What is the monthly payment on a $300,000 house with 10% down?
With 10% down ($30,000) on a $300,000 home you are borrowing $270,000. At 6.5% over 30 years your principal and interest payment is $1,707 per month. Add property tax and insurance and your total monthly payment is roughly $2,130. Note that with less than 20% down you will also pay PMI of approximately $90–$135 per month until you reach 20% equity.
What salary do I need to afford a $300,000 mortgage?
To comfortably afford a $300,000 mortgage at 6.5% with a total monthly payment of around $2,321, lenders generally want your annual income to be at least $85,000 to $100,000. If you have significant other debt like car loans or student loans your required income increases.

How much interest will I pay on a $300,000 mortgage?
On a $300,000 mortgage at 6.5% over 30 years you will pay approximately $382,633 in total interest over the life of the loan — more than the original loan amount. On a 15-year term at the same rate total interest drops to about $170,000. Making one extra mortgage payment per year can cut 4 to 5 years off a 30-year mortgage and save tens of thousands in interest.
Is $300,000 a lot for a mortgage?
In today's market $300,000 is a moderate mortgage amount. In lower cost-of-living areas it can buy a comfortable family home. In major metros like New York, Los Angeles, or San Francisco, $300,000 may be a small portion of a home's price. Whether it is affordable depends entirely on your income, other debts, and local property tax rates — not the number itself.
Can I pay off a $300,000 mortgage early?
Yes and it can save you a significant amount. On a 30-year $300,000 mortgage at 6.5%, paying an extra $200 per month reduces your payoff time by approximately 6 years and saves over $90,000 in interest. Even one extra payment per year makes a meaningful difference. Check your mortgage terms first as some loans have prepayment penalties, though these are increasingly rare.
