Mortgage overpayment calculator

Overpaying on your mortgage even by a fairly small amount can make a big difference to how much interest you’ll end up paying back in total. Our mortgage overpayment calculator will show you how both lump sum overpayments and monthly overpayments could help save you interest and reduce the term of your loan.

One thing you need make sure you do first is to check with your lender if there are any early repayment charges on your mortgage if you overpay, as any additional fees may wipe out the benefit of the extra mortgage overpayments.

Simply input some basic information about your mortgage as well as some details about the type of mortgage overpayment you are intending to make and our mortgage overpayment calculator will do the rest.
