Mortgage Calculator
Use this mortgage calculator to estimate your monthly payment and understand how interest rate, term length, down payment, property taxes, insurance, and HOA fees affect your total cost. This tool is built to give you clarity before you apply, compare lenders, or commit to a loan.
The second version of the mortgage calculator is useful when you want to move beyond a simple monthly payment estimate and look more closely at how different borrowing choices affect your long-term finances. Instead of relying on one number, you can test multiple scenarios by adjusting the loan amount, interest rate, repayment term, taxes, insurance, and down payment. This makes it easier to compare what happens if rates change, if you borrow less, or if you choose a shorter repayment timeline. It can also help you understand whether a home still feels affordable once the full monthly cost is included, not just the principal and interest portion. For users who want to go further, this page works well alongside the Amortization Calculator, the Down Payment Calculator, and the Refinance Calculator. It also helps to review trusted guidance from the Consumer Financial Protection Bureau and HUD so your planning is based on both realistic numbers and reliable educational information.
Start with the monthly payment calculator below. Then test “what-if” strategies using extra principal payments to see how much time and interest you could save.

How This Mortgage Calculator Works
A mortgage payment typically includes principal and interest, plus “escrow” items such as property taxes and homeowners insurance. Some properties may also include HOA dues. This calculator combines those variables to estimate a realistic monthly payment.
If you want to reduce long-term cost, the biggest levers are your interest rate, loan term, and how much principal you pay early. Even small additional payments can reduce total interest and shorten your loan.

What does a mortgage calculator estimate?
It estimates your monthly payment based on loan amount, interest rate, loan term, taxes, insurance, and optional HOA fees.
Does this include taxes and insurance?
Yes. You can manually include property taxes and homeowners insurance to generate a more accurate monthly estimate.
What is the difference between APR and interest rate?
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.
How does a larger down payment affect my mortgage?
A larger down payment reduces your loan amount, lowers your monthly payment, and decreases total interest paid over time.
How do extra principal payments help?
Extra payments reduce your outstanding balance faster, which decreases total interest and can shorten your loan term.
