Mortgage calculator
A mortgage payment is more than the loan. Enter the home price, down payment, interest rate, and term to see the principal-and-interest portion, then add your expected property tax and insurance for a realistic monthly total. The calculator uses the standard amortization formula lenders use, so it is a solid starting point before you compare official loan estimates. Remember that a down payment under 20% usually adds private mortgage insurance, and closing costs are separate from everything shown here.

The math, plainly
How it works
- 01
The loan amount is the home price minus your down payment.
- 02
Principal and interest use the standard amortization formula: loan × monthly rate ÷ (1 − (1 + monthly rate)⁻ⁿ).
- 03
Property tax and insurance are divided into monthly amounts and added to the payment; escrow for HOA dues or mortgage insurance is not included.
