How the Mortgage Calculator Tool Works

The calculator uses standard mortgage formulas to break down each part of the payment. It also shows additional insights such as total interest paid, months to payoff, and the estimated payoff date.

  • Taxes, insurance, and HOA: Property taxes, homeowners insurance, and HOA dues can have a significant impact on your total payment. The calculator includes dedicated fields so you get a full monthly cost that reflects real-life expenses.
  • Viewing results and amortization: Once you click “Calculate,” the tool displays loan amount, monthly principal and interest, taxes, insurance, and total payment. It also shows an amortization table for the first 12 months and allows you to download the full schedule in CSV or JSON format.
