Mortgage Payment Calculator (US)
How to use this US mortgage loan calculator
This calculator estimates your monthly mortgage payment using common U.S. home loan inputs. It includes principal and interest, plus optional housing costs like property taxes, homeowners insurance, PMI, and HOA dues. If you are comparing lenders, this is a quick way to test “what-if” scenarios before applying.
- Home Price: The purchase price of the property.
- Down Payment: Either a percentage or dollar amount.
- Interest Rate: The annual loan interest rate (APR used as an estimate).
- Loan Term: Typically 15 or 30 years for fixed-rate mortgages.
- Property Tax and Insurance: Annual values split into monthly estimates.
- PMI: Usually applies when your down payment is under 20%.
What your monthly mortgage payment includes
1) Principal and interest
Principal is the amount borrowed, and interest is the cost of borrowing. Your fixed monthly principal-and-interest payment is based on the amortization formula used by lenders in the United States. Early in the loan, a larger share goes to interest; later, more goes toward principal.
2) Property taxes
U.S. property taxes vary by county and state. Many mortgage servicers collect taxes monthly through escrow, then pay the bill when due. This calculator spreads your annual tax cost across 12 months for planning purposes.
3) Homeowners insurance
Insurance is also commonly escrowed. Premiums depend on location, replacement cost, and insurer. The monthly estimate helps you see your expected total housing payment rather than principal and interest alone.
4) PMI (private mortgage insurance)
If your loan-to-value (LTV) is above 80%, lenders may require PMI on conventional loans. This calculator applies PMI only when LTV is above 80% and a PMI rate is entered. Once your equity grows, PMI may be removable depending on loan rules.
5) HOA dues
If your home is in a community association, include monthly HOA fees. Even though HOA is not part of your loan itself, it affects affordability and debt-to-income calculations.
Why this matters for affordability
A common mistake is budgeting based only on principal and interest. In reality, taxes, insurance, and PMI can add hundreds of dollars each month. By calculating the full monthly payment, you get a more realistic view of what fits your budget.
You can also compare tradeoffs:
- Lower home price vs. longer loan term
- Higher down payment vs. keeping more cash on hand
- Buying now vs. waiting for different rates
Ways to lower your mortgage payment
- Increase your down payment: Reduces loan amount and may eliminate PMI.
- Improve your credit score: Better rates can significantly reduce interest costs.
- Shop multiple lenders: Compare APR, fees, and discount points.
- Appeal property taxes if over-assessed: Lower taxes can reduce escrowed payments.
- Choose a less expensive home: The most direct way to lower all housing costs.
Mortgage terms to know
Fixed-rate mortgage
The interest rate stays the same for the full term. This offers payment stability and predictable budgeting.
APR vs. interest rate
Interest rate is the borrowing cost on principal. APR includes some fees and is often higher. This calculator uses your entered rate as a practical estimate for planning, not as an exact loan disclosure.
Escrow
An account used by your lender/servicer to collect taxes and insurance monthly, then pay those bills on your behalf.
Important notes and limitations
This tool is for educational estimates. Actual loan offers depend on underwriting, credit profile, debt-to-income ratio, reserve requirements, and lender-specific fees. Closing costs, prepaid items, and rate buydowns are not included in the total monthly figure shown here.
For an exact payment and cash-to-close figure, request an official loan estimate from a licensed mortgage lender.
