How is it calculated?
We estimate your penalty (the greater of three months' interest and the IRD for fixed mortgages), add costs, and compare your payment before and after.
What should I do with the result?
Use it to set a budget or a target rate, then let lenders bid on your actual mortgage. Bids include rate, penalty method, prepayment and fees, so you can compare the full cost.
