Temporary interest-only mortgage calculator

This calculator can give an indication of your future monthly payments if you're considering a temporary 6-month interest-only period.

Before you get started

Information you'll need

The calculator asks for your outstanding balance, interest rate, the term that's left on your mortgage, and the remaining time left on your current interest rate. You can find these by logging on to online banking.

The calculator assumes the interest rate will change to the current Standard Variable Rate, for the remaining term left on your mortgage, after your current interest rate ends.

If you have a lifetime tracker or Home Buyer Variable rate, please input the same term in the 'Remaining mortgage term in years' and 'Remaining years on your current interest rate' fields.

If you have more than one loan part, you'll need to use the calculator for each loan part.

Our main information page has more on the Mortgage Charter, along with details of all the options available and how to apply for them.


The information provided by this calculator is a guide and should be used for indicative purposes only.


Disclaimer: Think carefully before securing other debts against your home. Your home may be repossessed if you do not keep up repayments on your mortgage.
