Mortgage Early Payment Calculator

Introduction: The Mortgage Early Payment Calculator is a powerful tool for individuals seeking to accelerate the payoff of their mortgage. By making extra monthly payments, borrowers can significantly reduce the overall loan term. This calculator helps estimate the new payoff term based on the initial loan amount, interest rate, loan term, and additional monthly payments.

Formula: The calculator uses a comprehensive approach. It first calculates the standard monthly mortgage payment using the loan amount, interest rate, and loan term. Then, it iteratively determines the new payoff term by subtracting the impact of extra monthly payments until the remaining balance reaches zero.

How to Use:

  1. Enter the total loan amount you are seeking.
  2. Input the annual interest rate for your mortgage.
  3. Specify the loan term in years.
  4. Enter the extra monthly payment you plan to make.
  5. Click the “Calculate” button to obtain an estimate of the new accelerated payoff term.

Example: Suppose you have a mortgage with a loan amount of $200,000, an interest rate of 4%, and a loan term of 30 years. If you decide to make an extra monthly payment of $100, the calculator will provide you with an estimate of the new accelerated payoff term.
