Prepaying Mortgage Calculator

Prepaying a mortgage can significantly reduce the amount of interest paid over the life of the loan and accelerate the process of homeownership. Understanding how much interest can be saved by prepaying the mortgage is crucial for making informed financial decisions.

Formula: The formula to calculate the total interest paid on a mortgage is: Total Interest = Loan Amount × (Interest Rate ÷ 100) × Loan Term

  1. Enter the loan amount in dollars.
  2. Input the annual interest rate as a percentage.
  3. Specify the loan term in years.
  4. Click the “Calculate” button to determine the total interest paid.

Example: Suppose you have a mortgage of $200,000 with an interest rate of 4% and a loan term of 30 years. Using the calculator, you find that the total interest paid over the life of the loan would be $144,000.
