What’s the Monthly Payment on a $400K Mortgage?

If you're looking to buy a home with a $400,000 mortgage, you probably want a clear answer to one big question: What will my monthly payment be?

It’s a question almost every homebuyer asks, and rightly so. Because “mortgage payment” isn’t just principal and interest. You’ve got taxes, insurance, sometimes private mortgage insurance (PMI), and possibly even HOA dues or flood coverage depending on the property.

Your monthly mortgage payment on a $400K loan will range from $2,500 to $3,200+, depending on your rate, term, and add-ons like property taxes and insurance. Let’s break it down so you can plan with clarity and confidence.

• Understand the full monthly cost of a $400,000 mortgage, including principal, interest, taxes, and insurance.
• Explore how credit score, down payment, and loan term impact your payment.
• Learn how to reduce your monthly cost with smart planning strategies.
• Compare fixed vs. adjustable rates and their long-term effects.

A typical mortgage payment includes:

• Principal – The amount you borrow.
• Interest – What your lender charges to loan you the money.
• Taxes – Property taxes are based on your local rates.
• Homeowners' Insurance – Required by lenders to protect your property.
• PMI (if applicable) – Needed if you put down less than 20%.
• HOA or Flood Insurance – Only applies in certain areas.

For example:

• A 30-year fixed mortgage at 7% interest: ~$2,660 (principal + interest only)
• Add estimated taxes & insurance: $500–$700/mo more
• Total Monthly Estimate: $3,160

Pro Tip: Your property taxes and insurance will vary based on location. Always get local quotes during your budgeting process.

Better scores = lower interest rates = lower monthly payments.

Putting 20% down ($80,000 on a $400K home) avoids PMI and reduces your principal.

• 30-Year Fixed: Lower monthly payments, higher total interest.
• 15-Year Fixed: Higher payments, but you save thousands in interest.

Every 1% rate difference can change your monthly payment by $200+.

Whether it's a conventional, FHA, or other loan product, requirements and payments will vary.

Heads Up: Always compare multiple lenders. A small rate difference could save you tens of thousands.

• Loan Amount: $320,000
• Monthly Payment (P&I): ~$2,022
• Add $600 for taxes and insurance
• Total: ~$2,622

• Loan Amount: $360,000
• Monthly Payment (P&I): ~$2,940
• Add $600 for taxes and insurance
• Total: ~$3,540

Always run the numbers using mortgage calculators and lender estimates.

• Improve your credit score before applying.
• Increase your down payment to reduce the principal.
• Buy mortgage points to lower your rate.
• Shop multiple lenders for the best terms.
• Avoid PMI by reaching 20% equity faster.

It depends on your rate, term, and taxes. On average, expect $2,500–$3,200/month.

It’s possible with low debt and a strong down payment. Aim for a 36% DTI (Debt-to-Income Ratio) or lower.

Most lenders look for 620+, but higher scores get better rates.

Improve your credit, shop lenders, increase your down payment, or consider adjustable-rate mortgages.

You might qualify for low-down payment programs like FHA or conventional 3% down options.
