A mortgage's real monthly cost is more than just principal and interest — property tax, insurance, and HOA fees add up. This calculator estimates your full monthly payment from a home price, down payment, term, and rate, plus whatever tax and insurance figures you enter.
How to use the mortgage calculator tool
- 1
Enter home price and down payment
The loan amount is calculated as the difference.
- 2
Set the term and interest rate
Typical terms are 15 or 30 years.
- 3
Add tax, insurance, and HOA
These get added on top of principal and interest for your real monthly cost.
