MORTGAGE OVERPAYMENT CALCULATOR

See how quickly you can pay your mortgage off

Our mortgage overpayment calculator helps you take control of your loan by showing how extra payments can shorten your term and save you money on interest. Whether you’re making monthly overpayments or a one-off lump sum, this tool provides an easy way to see the impact of your extra payments, helping you make informed decisions to pay off your mortgage faster and more efficiently.

Note. Typically you’re only allowed to overpay by 10% of your outstanding mortgage balance per year, so bear this in mind in particular if you wish to make recurring overpayments more than once a year.

Assumptions

In order to create these results, we have had to make a few assumptions:

1) Interest is charged monthly.

2) Interest rate stays the same over the term.

3) If you selected ‘Interest only’, we assume your standard monthly payment doesn’t decrease even if you pay off some of the balance.
