Mortgage calculator

Get an idea of how much you might be able to borrow with our mortgage calculator. 

You’ll see the estimated amount you’d pay each month. We’ll also show you our current deals and interest rates that best fit your needs.

This calculator is designed for customers living in the Channel Islands or the Isle of Man.

The figures you will see are based on Capital and Interest repayment mortgages. For Interest Only estimates, please speak with a Mortgage Arranger in branch.

Information on our mortgages for customers in the United Kingdom.


The figure you see is based on the information you give us. It is not a mortgage offer.

Before we agree a mortgage, we’ll conduct a full credit search and check you meet our lending requirements.

If using Internet Explorer, you will need to open the calculator in a new browser tab or window.
