Switch to a repayment

Repayment calculator

This calculator illustrates the potential impact of switching from Interest Only to a Repayment mortgage. Simply enter the key details about your mortgage and the tool will illustrate the differences between these two payment methods.

With a Repayment mortgage, your monthly payments will be higher as they cover the interest on the amount you've borrowed and they will also reduce the balance of your loan. However, provided you stay on track with your monthly payments, your mortgage will be completely paid off at the end of the term.

Flexible term

Alter the remaining term to illustrate the effect on your monthly payments, interest paid and total amount payable over the term.




The maximum term available to you is your
current mortgage term.
