What is a Prepayment Penalty?
A prepayment penalty is a fee charged by a lender when a borrower pays off all or part of their mortgage before the end of the agreed term.
Why do Prepayment Penalties Matter in Real Estate
In Canada, many mortgage agreements — especially fixed-rate contracts — include clauses that penalize borrowers for paying off their mortgage early. This could happen through refinancing, selling the home, or making large lump-sum payments outside the allowed annual prepayment limit.The penalty is usually calculated as the greater of:
- Three months' interest, or
- An interest rate differential (IRD), which compares the contract rate to current rates over the remaining term
Prepayment penalties can amount to thousands of dollars and often surprise borrowers who are unaware of the clause. Understanding the details in your mortgage contract can help you plan refinancing or selling without incurring unexpected costs.
Borrowers looking for flexibility may consider mortgages with prepayment privileges or lower penalties, and should always confirm the specific terms with their lender before signing.
Example of a Prepayment Penalty in Action
A homeowner with a fixed mortgage rate of 5% breaks their mortgage two years early. Because current rates have dropped to 3%, they owe a $7,000 prepayment penalty based on the IRD.
