Rate Change Calculator

Use our Rate Change Calculator to get an idea of how much a monthly mortgage payment might change by.

Where a mortgage is made up of a number of variable rate sub-accounts or parts, you’ll need to complete separate calculations for each one.

If a mortgage is affected by a rate change, we will always write to the customer to let them know their new monthly payment ahead of it being taken.

Your customer can find the current mortgage details in their most recent annual mortage statement.
