Understanding Your Mortgage Loan Payment Results

Once you calculate your mortgage payment, the calculator will provide:

  • Your estimated monthly mortgage payment (including principal and interest).
  • The total amount paid over the life of the loan, including principal and interest.
  • The total interest paid over the course of the loan.

Why the Mortgage Loan Rate Matters

Your mortgage loan rate significantly affects your monthly payments and the total cost of your loan. A higher interest rate means higher monthly payments and more interest paid over time. On the other hand, a lower interest rate can help reduce both your monthly payments and the total amount you will pay in interest.
