How it works

Four inputs. One monthly number.

The calculator uses your home price minus your down payment to estimate the loan amount, then applies the interest rate and amortization period to calculate a monthly payment.

  • A larger down payment lowers the loan amount and the monthly payment.
  • A shorter amortization increases the payment but reduces total interest over time.
  • Everything runs in your browser. Nothing is saved, tracked, or sent anywhere.
