Mortgage Payment Calculator: Estimate Your Monthly Housing Cost
Use it to: Estimate a monthly housing payment by combining principal and interest with property tax and homeowners insurance. Add mortgage insurance or association dues separately when they apply.
Build a monthly housing estimate from principal, interest, taxes, insurance, mortgage insurance and HOA dues.
Build the payment from its separate parts
Start with the loan, then add the ownership costs that do not disappear when the rate changes.
The rate controls only one part of the monthly total
The calculator subtracts the down payment from the home price, amortizes that loan balance over the selected term and adds one-twelfth of annual property tax and insurance. Monthly mortgage insurance and HOA dues are then added as separate lines.
Use the higher-rate check as a budget test
The result also prices the same loan at one percentage point above your entry. It is not a rate forecast. It shows how much room your budget has if the quote changes before you lock.
Before treating the estimate as affordable
Enter the purchase price and down payment.
Use the quoted note rate and loan term.
Add annual tax and insurance estimates from reliable local documents.
Run a second case with a higher rate to test affordability.
Check the calculator against the disclosure
A useful estimate still depends on accurate inputs. These official resources explain the terms behind this tool.

Before you rely on the number
Does this result include closing costs?
No. Closing costs affect cash to close and APR but are not part of the monthly estimate shown here.
Why is a lender's payment different?
A lender may use different tax, insurance, mortgage-insurance or rounding assumptions. Compare the inputs before comparing results.
