About this tool
Home buying decisions usually start with one question: what would the monthly payment look like? Mortgage Calculator estimates principal and interest from the home price, down payment, interest rate, and loan term so you can compare scenarios before talking to a lender. Changing the down payment or term can dramatically shift both the monthly payment and the total interest paid over time. This tool is meant for planning and comparison, not for final underwriting. Real mortgages include property tax, homeowners insurance, PMI, HOA fees, closing costs, and rate-lock details that are not modeled here. Verify every number with official lender disclosures before making an offer or signing loan documents. Calculations run locally in your browser during normal use.
Common scenarios
Down payment comparison
See how a larger down payment changes monthly payment and total interest.
Rate shopping
