Pay Down Mortgage Calculator

Introduction: Welcome to our Pay Down Mortgage Calculator, a powerful tool designed to help you visualize the benefits of making extra monthly payments on your mortgage. Whether you’ve received a windfall or are looking to increase your monthly contributions, this calculator will show you how paying down your mortgage faster can save you money in the long run.

Formula: To calculate the updated monthly payment after making additional monthly payments, we use the standard formula for a fixed-rate mortgage:



  • M is the updated monthly mortgage payment.
  • P is the current loan principal.
  • r is the monthly interest rate (annual interest rate divided by 12 and converted to a decimal).
  • n is the total number of payments (loan term in years multiplied by 12).

How to Use:

  1. Enter the current loan principal.
  2. Input the additional monthly payment you plan to make.
  3. Specify the annual interest rate.
  4. Set the loan term in years.
  5. Click the “Calculate” button to get your updated monthly payment.

Example: For example, if you have a current loan principal of $200,000, an annual interest rate of 4%, a loan term of 30 years, and you plan to make an additional monthly payment of $100, the calculator will show you the updated monthly payment.


  1. Q: How does making additional payments impact my mortgage? A: Additional payments reduce the principal faster, resulting in interest savings and a shorter loan term.
  2. Q: Can I use this calculator for adjustable-rate mortgages? A: This calculator is designed for fixed-rate mortgages; results for adjustable-rate mortgages may vary.
  3. Q: Are there penalties for making extra mortgage payments? A: Many loans allow extra payments, but it’s essential to check your specific loan terms for prepayment penalties.
  4. Q: Can I see the total interest savings over the loan term? A: The calculator provides the updated monthly payment, but the total interest savings can be calculated by comparing the total interest paid before and after additional payments.

Conclusion: Our Pay Down Mortgage Calculator empowers you to take control of your mortgage payoff journey. By making additional payments, you can potentially save on interest and achieve financial freedom sooner. Use this tool to make informed decisions about accelerating your mortgage payoff and building equity in your home. Always consult with financial advisors for personalized advice based on your specific circumstances.
