Mortgage Calculator
Use this mortgage calculator to estimate monthly payment costs based on home price, down payment, loan term, rate, taxes, insurance, and HOA dues. This page is designed to help you test realistic housing scenarios before you make an offer, compare financing options, or commit to a lender.
You can also use the extra principal section below to see how additional monthly payments may shorten your loan and reduce total interest. If you want a deeper breakdown after testing numbers here, continue with the Amortization Calculator, the Down Payment Calculator, or the Refinance Calculator.
Mortgage planning works best when you compare multiple outcomes instead of relying on a single rough estimate. The Consumer Financial Protection Bureau and HUD both recommend reviewing full housing costs carefully, which is exactly what this calculator is built to help you do.
Monthly Payment (Principal + Interest + Taxes + Insurance + HOA)

How This Mortgage Calculator Works
A mortgage payment usually includes more than principal and interest. Property taxes, homeowners insurance, and in some cases HOA dues can all affect the true monthly cost of owning a home. That is why this page estimates a more realistic payment instead of only showing the base loan amount.
This mortgage calculator is most useful when you compare several scenarios instead of stopping after one estimate. You can test a larger down payment, a lower or higher rate, a 15-year versus 30-year term, or an extra monthly payment strategy to see how each decision changes both short-term affordability and long-term borrowing cost.
If you want deeper support beyond the calculator itself, the Mortgage Guides section can help explain affordability, amortization, ARMs, and common mortgage mistakes. For structured planning, the Mortgage Products & Spreadsheets page can help you compare strategies more thoroughly over time.

Yes. You can manually include property taxes and homeowners insurance to generate a more accurate monthly estimate.
The interest rate reflects the cost of borrowing. APR can include the interest rate plus certain lender fees, giving a broader view of loan cost.
A larger down payment reduces your loan amount, lowers your monthly payment, and decreases total interest paid over time.
Extra payments reduce your outstanding balance faster, which decreases total interest and can shorten your loan term.
This calculator provides planning estimates. Final numbers depend on lender terms, fees, and underwriting.

Closing thought: The best mortgage decisions happen when you can compare scenarios clearly. Use this page to stress-test the numbers, then move to the amortization and refinance tools to see how your choices play out over time.
