Overpayment Calculator

Mortgage overpayment

This tool illustrates the positive effect that making overpayments can have on your mortgage. Simply enter some basic details about your mortgage and the amount you can afford to overpay. Whether it's a regular monthly overpayment or a one-off amount, you might be surprised how much difference it makes.

Please note - The calculator assumes your current interest rate will remain the same over the remaining term of your mortgage. In reality, interest rates could rise and fall and this will affect the amount you overpay. Please refer to your original terms and conditions to see if you are eligible to make overpayments.
