Mortgage Overpayment Calculator

This is the amount outstanding on your most recent statement - check your paper or online banking to find it, or give your lender a call if you can't.

NB it isn't the same amount you borrowed initially, as each payment you make reduces what you owe.

This is how long until you are completely mortgage free. So if you originally took out a 25 year mortgage five years ago, then enter 20 into here.

This should be on your statement, application info or can be obtained from your lender.

A repayment mortgage means that, over the length of the loan, you will repay the full amount you borrowed as well as some interest.

An interest-only mortgage means you only pay the interest, and once the loan is over (eg, 25 years after you took it out), you still owe the amount you borrowed.

If you don't know which type you have, call your lender to ask.
