Mortgage Buydown Calculator

Introduction: The Mortgage Buydown Calculator is a valuable tool for individuals considering a mortgage buydown, a strategy where upfront points are paid to reduce the interest rate and lower monthly payments. This calculator helps estimate the adjusted monthly payment based on loan amount, interest rate, loan term, and buydown points.

Formula: The calculator uses a two-step process. First, it calculates the standard monthly mortgage payment using the loan amount, interest rate, and loan term. Then, it adjusts the payment by subtracting the impact of buydown points, which reduce the interest rate.

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 buydown points you are considering.
  5. Click the “Calculate” button to obtain an estimate of your adjusted monthly mortgage payment.

Example: Suppose you have a loan amount of $250,000, an interest rate of 4%, a loan term of 30 years, and you are considering paying 2 buydown points. After entering these values and clicking “Calculate,” the tool will provide you with the estimated adjusted monthly mortgage payment.
