Pay Extra On Mortgage Calculator

Introduction: Welcome to our Pay Extra On Mortgage Calculator, a valuable tool designed to assist you in understanding the benefits of making extra monthly payments on your mortgage. By inputting your current loan details and the additional amount you plan to pay each month, this calculator provides insights into how these extra payments can shorten your loan term and reduce interest payments.

Formula: The calculator employs the standard formula for a fixed-rate mortgage to calculate the updated monthly payment after making additional monthly payments. This formula is based on the principles of amortization, where a portion of each payment goes towards both the principal and the interest.

How to Use:

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

Example: Consider a scenario where you have a current loan principal of $250,000, an annual interest rate of 4%, and a loan term of 30 years. If you plan to make an extra monthly payment of $100, the calculator will show you the updated monthly payment reflecting the impact of this additional contribution.


  1. Q: How does making extra payments affect my mortgage? A: Extra payments reduce the principal faster, resulting in a shorter loan term and potential interest savings.
  2. Q: Are there penalties for making extra mortgage payments? A: Many loans allow extra payments without penalties, but it’s crucial to check your specific loan terms.
  3. 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.
  4. Q: Can I see the total interest savings over the loan term? A: While the calculator provides the updated monthly payment, you can calculate total interest savings by comparing the total interest paid before and after additional payments.

Conclusion: Our Pay Extra On Mortgage Calculator is a valuable tool for homeowners looking to optimize their mortgage payoff strategy. Use this calculator to explore the benefits of making extra payments and take proactive steps towards financial freedom. Always consult with financial advisors for personalized advice based on your specific circumstances.
