ABOUT THIS TOOL
What is the Mortgage Calculator?
A mortgage calculator estimates the principal-and-interest portion of a fixed-rate home loan. It helps compare prices, down payments, rates and repayment terms before requesting lender quotes.
How the result is calculated
The standard amortization formula uses loan principal, monthly interest rate and number of monthly payments. Taxes, insurance, HOA fees and lender costs are not included.
Practical example
For a $400,000 home with $80,000 down, the financed principal is $320,000. Changing the rate or term shows how monthly cost and total interest respond.
