A $300,000 mortgage could have a monthly principal-and-interest payment of about $1,798.65 with a hypothetical 6% fixed annual interest rate and a 30-year term. That figure is only the loan payment. Property taxes, homeowners insurance, mortgage insurance, and other housing costs may increase the amount you need to budget.
Quick answer: $300,000 loan at 6% for 30 years
$1,798.65 / monthAssumptions: $300,000 loan principal; 6.00% illustrative fixed annual interest rate; 30-year (360-payment) term; fully amortizing loan; principal and interest only. This is not a current rate quote and excludes taxes, homeowners insurance, PMI, HOA dues, and other costs.
Estimated Monthly Payments on a $300,000 Mortgage
The table shows how the principal-and-interest payment changes when the interest rate or term changes. The $300,000 figure is the amount borrowed, not the purchase price of the home. If you are shopping for a $300,000 home and make a down payment, your loan amount would generally be lower than $300,000.
| Illustrative annual rate | 15-year term | 30-year term |
|---|---|---|
| 5.00% | $2,372.38 | $1,610.46 |
| 6.00% | $2,531.57 | $1,798.65 |
| 7.00% | $2,696.48 | $1,995.91 |
| 8.00% | $2,866.96 | $2,201.29 |
Values are calculated using the standard fixed-rate amortization formula and rounded to the nearest cent. They are not actual market offers. Taxes, insurance, PMI, HOA dues, points, fees, and other charges are excluded.
Why the Monthly Payment Changes
1. Interest Rate
The interest rate affects how much interest accrues on the outstanding loan balance. With the same $300,000 principal and loan term, a higher rate produces a higher scheduled principal-and-interest payment. The rates in the table are deliberately illustrative; check a written Loan Estimate for an actual loan offer.
2. Loan Term
The term is the time allowed to repay the loan. A 15-year loan has fewer payments, so its monthly principal-and-interest payment is usually higher than a comparable 30-year loan. A longer term spreads repayment across more months and usually lowers the scheduled monthly payment, but it generally means paying more total interest if the loan is held to term.
3. Down Payment
A larger down payment generally reduces the amount borrowed. For example, if the home price were $300,000 and the down payment were $60,000, the starting loan amount would be $240,000 before any financed costs. That is a different scenario from the table above, which assumes the loan itself is $300,000. Down-payment rules and available loan options depend on the program and lender.
4. Property Taxes
Property taxes are based on local rules and the property's taxable value. They are not included in the principal-and-interest figures above. A servicer may collect them through escrow, or you may pay the taxing authority directly. The actual amount can vary by location and over time.
5. Homeowners Insurance
Homeowners insurance is a separate ownership cost. If a lender or servicer collects the premium through escrow, the amount may be included in the monthly payment you send to the servicer. Use a quote for the property and coverage you are considering rather than a generic national estimate.
6. Private Mortgage Insurance (PMI)
PMI may be required for some conventional loans when the down payment is below 20% of the home's purchase price. PMI protects the lender, not the borrower, and adds to the borrower's cost. Requirements and premiums vary, so ask the lender for the actual monthly amount and applicable cancellation rules.
What Else Is Included in a Mortgage Payment?
Principal and interest are not always the full amount due each month. A common way to group four payment components is PITI: principal, interest, taxes, and homeowners insurance. Mortgage insurance may be added when applicable. Some homeowners also have HOA or condominium dues, flood insurance, utilities, maintenance, or other costs that are not included in a standard PITI calculation.
When taxes and homeowners insurance are paid through an escrow account, the servicer collects a portion each month and pays those bills when due. If escrow is not used, you still need to budget for the bills separately. The CFPB recommends reviewing the Estimated Total Monthly Payment on the Loan Estimate instead of relying only on the principal-and-interest figure.

How to Estimate Your Own $300,000 Mortgage
- Confirm whether $300,000 is your target home price or the amount you plan to borrow.
- Use the interest rate and term from a real Loan Estimate or lender quote when available.
- Get a property-specific estimate of property taxes and homeowners insurance.
- Ask whether mortgage insurance applies and request its actual quoted cost.
- Include HOA fees and other ownership costs separately in your budget.
Methodology and Assumptions
For the examples in this article, the stated loan amount is treated as the amount borrowed, not the home's purchase price. Principal and interest are calculated using a standard fixed-rate amortization formula: the monthly rate is the annual rate divided by 12, and the payment count is the loan term in years multiplied by 12.
The examples use hypothetical rates of 5%, 6%, 7%, and 8% and 15- or 30-year terms. They are not current market quotes. Taxes, homeowners insurance, PMI, HOA dues, and closing costs are excluded unless specifically noted.

Frequently Asked Questions
How much is a $300,000 mortgage per month at 6%?
For a $300,000 loan at an illustrative 6% fixed annual rate, principal and interest are about $1,798.65 per month over 30 years, or about $2,531.57 over 15 years. Taxes, insurance, PMI, and other costs are additional.
Does a $300,000 mortgage mean a $300,000 house?
Not necessarily. A $300,000 mortgage usually refers to the amount borrowed. If the home costs $300,000 and you make a down payment, the loan amount would normally be less than the purchase price, assuming no financed costs.
Does the monthly payment include property taxes and insurance?
It may. Those costs are often collected through escrow, but not every loan uses an escrow account. Even when paid separately, taxes and insurance are part of the cost of owning the home and should be included in your budget.
How much more does a 15-year mortgage cost each month than a 30-year mortgage?
At the illustrative 6% rate used here, a $300,000 loan has a principal-and-interest payment of about $2,531.57 over 15 years and $1,798.65 over 30 years. The exact difference changes with the rate and loan terms.
Will my mortgage payment stay the same?
For a fixed-rate mortgage, the scheduled principal-and-interest amount generally stays the same. The total amount paid each month can still change if escrowed property taxes or insurance premiums change. Adjustable-rate mortgages can also change according to the loan agreement.
Conclusion
A $300,000 loan does not have one universal monthly payment. The amount depends primarily on the interest rate and repayment term, while property taxes, homeowners insurance, PMI, and other housing costs affect the broader monthly budget. Compare the full estimated payment in your Loan Estimate and use property-specific figures whenever possible.
