Mortgage Exit Cost Checker

This tool calculates your early repayment charge if you leave your current mortgage deal before the fixed period ends, and shows how that cost changes over time as the tie-in period reduces. It helps you understand whether remortgaging or switching products now, or waiting, is the more cost-effective option.

How early repayment charges work

ERCs are typically a percentage of the outstanding balance, reducing each year of the fixed period.

Portability and moving home

Some mortgages can be ported to a new property, which avoids the ERC, but not all lenders or situations allow it.

The cost of switching vs waiting

Understanding the exit cost lets you compare it against the savings from a better rate.
