Mortgage Calculator

What this calculator does

The Mortgage Calculator estimates how much a home loan could cost each month and over the full term. It combines the loan amount, interest rate, and repayment term, then lets you add common housing costs such as property tax, homeowners insurance, and HOA fees.

What to enter

Start with the home price, choose whether your down payment is a fixed amount or a percentage, then enter the annual interest rate and loan term in years. Optional tax, insurance, and HOA values help you move from a bare loan estimate to a more realistic monthly housing cost.

How the estimate is calculated

Principal and interest are calculated with the standard amortizing loan formula. The calculator then spreads annual property tax and annual insurance into monthly amounts, adds any monthly HOA fee, and shows the combined payment together with total interest and estimated total paid over the loan term.

Important limitations

This tool provides an estimate, not a lender quote. Real mortgage payments can vary because of closing costs, private mortgage insurance, escrow adjustments, taxes that change over time, rate locks, and lender-specific fees. Use it for planning and comparison, then confirm final numbers with your lender or financial advisor.
