How Does the Mortgage Overpayment Calculator Work?

Our calculator uses the following details to provide accurate estimates:

  • 1. Loan Amount: The total amount borrowed for your mortgage.
  • 2. Interest Rate:The annual interest rate of your mortgage.
  • 3. Loan Term: The original mortgage term in years and months.
  • 4. Monthly Overpayment: The additional amount you plan to pay each month.
After entering these details, the calculator will:
  • Display the new monthly payment schedule.
  • Show how much you’ll save in interest by making regular overpayments.
  • Compare the original and revised mortgage terms.

  • 2. Shorten Your Mortgage Term
  • Regular overpayments allow you to pay off your mortgage earlier, giving you financial freedom sooner.
  • 2. 3. Make Informed Decisions
  • Understand the real benefits of overpaying and adjust your budget accordingly.
