# What Every Canadian Borrower Needs To Know About Fixed-Rate Mortgage Penalties

## Last Updated on January 10th, 2021

Today’s post provides a detailed explanation of how Canadian fixed-rate mortgage penalties are calculated.

(You can also check out this interview I did with Rob Carrick at the Globe and Mail as part of his Carrick Talks Money series.)

The penalty terms in your mortgage contract are an often overlooked detail that can, and often does, have a huge impact on your overall borrowing cost. Unsurprisingly, the lenders who charge the highest penalties haven’t been going out of their way to warn you about them.

As you will see, there is a reason that the small print is small.

To put this in perspective, if we assume that mortgage rates remain at today’s levels, we’re talking about a difference in penalties of between $6,500 and $8,000 on a $250,000 five-year fixed-rate mortgage that starts today and is broken in three years’ time.

Although almost no one plans to break a mortgage early, life is unpredictable and about a third of borrowers do end up doing it, so these are real costs that are being borne by a large number of Canadians.

Fixed-rate penalties are of particular importance in the current interest-rate environment because the differences in the methods used to calculate them are actually more pronounced when fixed-mortgage rates stay relatively flat over an extended period – which is exactly the scenario that I am forecasting now.

Now let’s make you an expert on the single most important small-print detail in your fixed-rate mortgage contract.

For starters, while it may come as a surprise, almost all Canadian lenders use the same basic wording for their fixed-rate mortgage penalties, which they typically describe as “the greater of three months interest or interest-rate differential (IRD)”.

The key difference is in the actual rates that are used in the IRD calculation, and to illustrate these with examples, let’s start with the following assumptions:

- You have a five-year fixed-rate mortgage at a rate of 1.84% with a current balance of $250,000.
- You are three years into your five-year term (with two years remaining).
- Interest rates are the same today as they were when you first got your loan.

First, let’s calculate the cost of three months’ interest. Here is the formula:Lenders simply compare this cost to their IRD calculation and charge you the higher of the two amounts.

IRD penalties are typically calculated using one of three methods: Standard, Discounted or Posted.

**The Standard IRD Calculation**

When using a standard IRD penalty calculation, your lender takes the difference between your contract rate (1.84%) and their current rate that most closely matches the time remaining on your term. Because you have two years left on your mortgage, in this case the lender would compare your contract rate to their current two-year fixed rate. (We’ll use 1.79%, which is a competitive two-year rate today.)

The lender takes the difference between these two rates (which works out to 0.05% in this example), and multiplies it by both your mortgage balance and the time remaining on your mortgage (expressed as the number of months remaining on your mortgage divided by twelve).

Here is the complete formula:And here is a table that summarizes where each number in this Standard IRD penalty came from:That’s it! If you understand this example, then you have mastered the Standard IRD calculation. This is used by a wide range of well-established lenders who compete with each other to offer borrowers the best mortgage rates available.

In this case the cost of three months’ interest ($1,150) is greater than the lender’s Standard IRD calculation ($250), so you would have to pay $1,150 to break your mortgage.

Now here is where a little knowledge can save you some serious money.

Other well-known lenders have tweaked their IRD calculations to skew the interest rates used in their formulas heavily in their favour, and as you will see, that can have a huge impact on the size of your penalty.

**The Discounted-Rate IRD Calculation **

This is IRD calculation is used by RBC, BMO, TD, Scotia and National Bank (and don’t let the name fool you!).

The key difference in the Discounted Rate IRD method is that the lender takes your contract rate and compares it to the posted rate that most closely matches your remaining term MINUS the original discount you got off of their five-year posted rate.

To put that in today’s terms, the Big Six Banks’ five-year posted rates currently average 4.79%, so a contract rate of 1.84% comes with an average Big Six discount of 2.95%.

To highlight with a specific example, here is the IRD penalty wording taken straight from TD’s website. I have underlined the key section:

*[Your contract rate will be reduced by] the current interest rate that we can now charge for a mortgage term offered by us with the term closest to your remaining term. The interest rate will be our posted interest rate for the term minus the most recent discount you received.*

In other words, lenders who use this method will take the original discount they gave you off of their five-year posted rate and apply that same discount to the posted two-year rate they use to calculate your penalty.

This subtle tweak to the IRD fine-print wording makes a huge difference to the cost of your penalty, and is blatantly one-sided because lenders don’t discount their shorter-term fixed rates nearly as deeply as they do their five-year fixed rates. (For example, the gap between TD’s five-year posted and contract rates is 2.95% today, whereas the gap between its two-year posted and contract rates is 0.45%.)

Look at the difference that this wording makes to your IRD penalty calculation:The table below summarizes the key numbers that are used in the Discounted Rate IRD formula that is used both by TD and by most of the other Big Six banks:I know. Ouch.

But fasten your seat belt because another major lender will dig even deeper into your wallet …

**The Posted-Rate IRD Calculation**

CIBC uses the posted-rate method to calculate its penalties.

If we used the same rates in this example that we used in the discounted-rate method outlined above, the posted-rate method would yield the same sized penalty. But CIBC’s posted rates tend to be higher (which they were at the time this post was written), and for that reason, their penalties earn the moniker of “The Grand Daddy of Them All”.

In this IRD variation, CIBC calculates your penalty by taking the five-year posted rate that they were offering when you got your mortgage and compares it to their current posted rate that most closely matches the time remaining on your term.

Here is a sample of the wording used to explain how the penalty is calculated (taken from CIBC’s website). I have underlined the key sections :

*The interest rate differential amount is the difference between the Interest on the Prepaid Amount for the remainder of the term at the posted rate at the time you took out the mortgage, and interest on the Prepaid Amount for the Remainder of the Term using a Comparable Posted Rate. Interest is calculated at the interest rate posted by [the lender] for a mortgage product similar to your mortgage product on the date the payout statement is prepared.*

Now CIBC’s defense of this tactic is that they substitute posted rates for both your original rate and the rate that most closely matches your remaining term. But as we have already outlined above, this is a terrible trade that no informed person would make because Big Six lenders must make huge discounts to their five-year posted rates to make them competitive with market five-year fixed rates, and those same discounts shrink dramatically on shorter fixed-rate terms.

Here is the a breakdown of CIBC’s posted-rate penalty calculation:The table below summarizes the key inputs that CIBC uses:Surprised? Don’t be. These inflated mortgage penalties generate substantial profits for the lenders who use them and when uninformed borrowers choose to negotiate directly with a Big Six lender, is it so hard to imagine that these lenders would use their small print to maximize their potential profitability?

To be clear, I don’t have a problem with mortgage penalties in principle. When you break a mortgage contract, your lender incurs costs when they unwind agreements related to your loan (these agreements can relate to hedging, servicing, securitization etc.). The penalty charged is supposed to cover these costs while also recouping part of the lender’s lost profit, and fair enough – that’s why they’re called “closed mortgages”.

But is it fair for some lenders to use these early terminations as “gotcha” moments?

The vast majority of Canadian mortgage borrowers do not have any idea that there are significant differences in the way fixed-rate mortgage penalties are calculated, and the largest Canadian lenders, who have milked that lack of awareness to their advantage for years, have been in no hurry to explain it to them.

While our federal government has repeatedly acknowledged the public’s pain and frustration over these unfair practices (which can easily be referenced with a Google search for “Canadian mortgage penalties”), it has been frustratingly slow in forcing lenders to provide more transparent disclosure.

In the meantime, it is my hope that this post will help better inform Canadian consumers about the important differences in the way lenders calculate their fixed-rate mortgage penalties.

Forewarned is forearmed.

This is a great article, thanks for providing insights into what’s hidden on the terms and conditions when breaking a mortgage.

Very informative and easy to understand!

Thanks Charlene.

Thanks so much for your help!

Very clearly explained and very important to know!

Glad to hear you found the post useful Maria.

This is great information and so clearly illustrated David! I am going to post on my SM sites – too many clients have a hard time understanding all the ins and outs of mortgages and as a REALTOR, this will help me explain to them.

Thank you!

Thanks for your comment Anne-Louise and glad you found the post useful.

Best,

Dave

Thank you sir. I am trying to understand the game before entering it, and your blog is really helpful!

You are welcome Bastien. Glad you found my post useful.

Best,

Dave

Is it the responsibility of a mortgage broker to warn a client about high penalties before signing mortgage documents?

Hi Natasha,

Any broker worth their salt should be providing each borrower with a detailed breakdown of the terms and conditions their mortgage contract, including a thorough explanation of how the lender’s penalties are calculated and a candid assessment of how those penalties compare with alternative options.

Best,

Dave
