An estimate for planning only, and not financial advice. Lenders include costs this calculator does not know about, so treat the figure as a starting point rather than an offer.

A mortgage payment is the loan amount spread over the term at a fixed rate, plus the escrow your lender collects for property tax and insurance. On a $450,000 home with 20% down over 30 years at 6.75%, principal and interest come to about $2,335 a month before escrow.
How to use this calculator
1Enter the home price and the deposit you expect to put down.
2Set the term and the rate you have been quoted, not the advertised rate.
3Open the escrow group and add property tax, insurance and any HOA fee to see the real monthly figure.
The schedule below is the part worth reading. In the first year of a thirty-year loan at these rates, roughly four fifths of every payment is interest, and the balance barely moves. That ratio flips somewhere around year twenty-one, which is why an extra payment made early is worth several made late.
Questions
Lenders add mortgage insurance below 20% down, plus origination and escrow set-up costs. This calculator shows principal, interest and the escrow you enter, nothing else.
