See what your payment could be once your fixed rate ends

Enter your outstanding balance, the term left on your mortgage and a rate to test, and this calculator works out a monthly repayment in seconds. It is not a quote, and it will not match your lender's actual offer, but it gives you a figure to work from before you speak to anyone.

See what your monthly repayment could actually be

Your monthly repayment depends on your outstanding balance, the interest rate and the remaining term, and a small change to any one of these moves the number more than you'd expect. This calculator works out a repayment figure from what you enter, so you can see the effect before you commit to a new deal. It won't tell you which lender to choose, but it gives you a figure to work from.

  • Works for repayment and interest-only mortgages, so the figure matches how your loan actually reduces.
  • Recalculates instantly as you change the balance, rate or term, so you can compare a few scenarios in one sitting.
  • Gives you a number to take to a broker or lender.
