How to use the mortgage calculator
Enter the home price, your down payment, the interest rate, and the loan term. Optionally add your annual property tax and home insurance to see a fuller monthly figure. The calculator breaks the payment into principal and interest, tax, and insurance, and shows the loan amount you would actually borrow.
See the real monthly cost, not just the loan
The most common budgeting mistake homebuyers make is estimating only the principal and interest and forgetting the extras. Property taxes and insurance can add a meaningful amount to the monthly payment, and lenders usually collect them together with the loan in an escrow account. Including them here gives you a number much closer to what will actually leave your account each month.
Test the levers before you commit
Because the result updates instantly, use the calculator to explore how each input moves your payment. A larger down payment shrinks the loan and the monthly cost; a lower rate or shorter term changes the total interest dramatically. Trying a few combinations helps you find a payment that fits your budget while keeping the lifetime cost sensible. These are estimates for planning — your lender’s official quote, including any mortgage insurance or fees, is the binding figure.
