Prepayment Penalty

The fee charged when you pay off or break a mortgage early — the greater of three months' interest or the IRD calculation for fixed-rate mortgages.

A prepayment penalty is the fee your lender charges when you pay off or break your mortgage before the term ends. For variable-rate mortgages, the penalty is simply three months of interest at your current rate. For fixed-rate mortgages, the penalty is the greater of three months' interest or the Interest Rate Differential (IRD). You can also trigger prepayment penalties by prepaying more than your annual allowance (typically 15–20% of the original mortgage balance). Most mortgages allow annual prepayments and lump-sum payments within defined limits without penalty.
