How this is estimated

What the estimate assumes.

Variable. Usually three months’ interest on the balance.

Fixed. The greater of three months’ interest and the rate differential, which is the contract rate minus today’s rate for the remaining term, applied to the balance.

Not included. Discharge fees, portability, and any penalty waived by a lender. Confirm each figure with your lender.
