Fixed closed: you pay the GREATER of 3 months' interest or the IRD. Banks present-value the real charge, so actual figures often land slightly below this estimate.

Variable closed: 3 months' interest only — there is no IRD on a variable mortgage. This is why variable exit costs are small and predictable.

Frequently asked questions

How is a mortgage penalty calculated in Canada?

For a variable-rate mortgage the penalty is usually three months' interest. For a fixed-rate mortgage it is typically the greater of three months' interest or an interest-rate-differential (IRD) charge — and big-bank IRD, calculated off posted rates, can run into the thousands. Educational information, not advice.

What is the interest rate differential (IRD)?

The IRD is a penalty based on the difference between your mortgage rate and a comparison rate for the remaining term. The exact method varies by lender, which is why two mortgages with the same rate can have very different break penalties. Educational information, not advice.

How can I reduce my mortgage break penalty?

Options include using your annual prepayment privileges first, porting the mortgage to a new property, a blend-and-extend, or timing the break closer to maturity. Educational information, not advice.
