Estimate Your Monthly Mortgage Payment
Use this calculator to explore how the home price, down payment, interest rate, loan term, property taxes, homeowners insurance, HOA dues, and mortgage insurance may affect an estimated monthly housing payment.
This is an educational planning tool, not a loan quote or approval. A licensed lender must verify your eligibility, interest rate, loan costs, taxes, insurance, and final payment.

This calculator does not include closing costs, utilities, maintenance, repairs, special assessments, flood insurance, or every possible loan and property expense.
What the Estimated Payment Includes
A complete housing payment may contain more than the amount that reduces the mortgage balance. The categories below explain what you can include in this calculator.
Principal
The portion of the payment applied to the outstanding loan balance. Early in an amortizing loan, a smaller share generally goes to principal than later in the repayment schedule.
Interest
The cost charged by the lender for borrowing money. The rate, loan amount, loan term, points, and loan program can affect the monthly principal-and-interest payment.
Property Taxes
Property taxes are based on local assessments and tax rates. The monthly amount shown here is simply the annual estimate divided by twelve.
Homeowners Insurance
Homeowners insurance may protect against covered losses and is commonly required by lenders. Premiums vary by property, coverage, insurer, claims history, and risk factors.
Mortgage Insurance
Some loans require mortgage insurance, a guarantee fee, or a funding fee. The amount and duration depend on the loan program and buyer qualifications.
HOA Dues
Condominiums, townhomes, and some planned communities charge association dues. These are generally separate from the mortgage and may change over time.
Costs This Calculator Does Not Fully Predict
Closing Costs
Lender charges, appraisal, title, escrow, recording, prepaid items, and other transaction expenses are generally paid upfront and are not included in the monthly total.
Understand Closing CostsUtilities and Maintenance
Electricity, water, sewer, garbage, internet, repairs, landscaping, and routine maintenance can significantly affect the true monthly cost of ownership.
Special Property Expenses
Flood insurance, private road agreements, septic service, well maintenance, special assessments, leased equipment, and other property-specific expenses may apply.
Changing Taxes or Insurance
Taxes, insurance, HOA dues, and escrow payments can change after purchase. A fixed interest rate does not guarantee that the entire monthly housing payment remains fixed.
How to Use the Estimate When Planning a Purchase
Test More Than One Price
Compare several home prices rather than treating the maximum estimated payment as your target. Leave room for maintenance, savings, and expenses that are not included here.
Compare Down Payments
A different down payment changes the loan amount and may affect mortgage insurance, reserves, closing funds, and loan pricing. Keep enough money available for closing and emergencies.
Use a Lender's Actual Rate
Online rate examples may not match your credit, loan program, property, occupancy, points, or market conditions. Replace the example rate with a lender's current scenario when available.
Confirm Taxes and Insurance
Use property-specific tax information and an insurance estimate whenever possible. Generic assumptions can materially understate or overstate the monthly payment.
Review the Entire Loan
Compare interest rate, annual percentage rate, loan fees, mortgage insurance, prepayment terms, cash to close, and long-term cost—not only the monthly payment.
Get Pre-Approved
A lender can review income, assets, credit, debts, and documentation to provide a more meaningful price range and explain the loan options for which you may qualify.
