# How Much Will it Cost to Break My Mortgage with BMO?

If you find yourself in a situation where you are considering refinancing your mortgage, transferring it to another lender, or selling your house or condo before your current mortgage term is up, you must prepare yourself (and your budget) for the mortgage penalty you will incur by doing so. Otherwise known as a prepayment penalty, this fee is your lender’s way of penalizing you for breaking your mortgage contract early, and trying to recoup some of the interest charges they are losing in the process.

If your mortgage is with Bank of Montreal (BMO), and you think you’ll need to break it before your current mortgage term is up, here’s how your prepayment penalty will be calculated.

## What is a prepayment penalty?

A prepayment penalty is a charge issued to you by a lender if you break a mortgage with them. A mortgage is a financial contract, and the prepayment charge is your mortgage provider’s compensation for you leaving early. Because there are several variables in the calculations, prepayment penalties can vary greatly, even from the same lender.

## Calculating BMO mortgage penalties

While the banks all host their own prepayment penalty calculators now, many of them are confusing and ask for information that isn’t readily available, which makes the calculation that much more confusing. Because of this, we decided to take on the responsibility of calling each and every bank to find out exactly how they calculate their penalties and build an all-encompassing mortgage penalty calculator of our own.

Depending on if you have a fixed or variable rate mortgage, BMO will charge you one of two fees:

• Three months’ interest, or the
• Interest rate differential (IRD).

If you have a fixed rate mortgage, you have to pay the greater of the two. If you have a variable rate mortgage, however, you will always pay just three months’ interest. Let’s look at how both fees are calculated.

### Method 1: Three Months’ Interest

Three months’ interest is exactly that: the amount of interest you would have paid during three months of your existing mortgage term. While some lenders use their Prime rate, BMO calculates three months’ interest using your current mortgage rate. Here’s an example we put through our mortgage penalty calculator.

To calculate three months’ interest, BMO would multiply your current mortgage rate (we used 2.25% here, which is the same as Prime – 0.75% if you had a variable rate mortgage) by the remaining balance of your mortgage (\$300,000 in this example) and again by 0.25 (represented as 3/12 for the three-month period out of the year).

In this example, because you had a variable rate mortgage, BMO would charge you the three months’ interest penalty which amounts to \$1,688. However, if you had a fixed rate mortgage, you would need to find out if three months’ interest was more or less expensive than the interest rate differential, because you have to pay whichever one is more…

### Method 2: Interest Rate Differential

The interest rate differential (IRD) is your lender’s way of finding out how much interest they’ll be losing by letting you break your mortgage early – and making you pay it. To calculate the IRD, your lender looks at your mortgage rate and how much time is left in your mortgage term, and the mortgage rate they could charge someone now for a new term that’s the length of the remainder of your term.

Instead of looking at your current mortgage rate, however, BMO finds the posted rate from the day you signed your mortgage and subtracts today’s posted rate for a new mortgage that would cover the remainder of your term. Are you confused yet? IRD calculations are one of the biggest reasons we knew we had to create a mortgage penalty calculator.

Using the same numbers from our previous example, let’s say the balance of your mortgage is \$300,000 and you have 23 months left in your term. BMO would first find out what the posted rate was for a 5-year fixed term on the day you signed your current mortgage (it was 5.49%). Then, BMO would determine which of their mortgage products someone would need to get today, in order to make up the remainder of your term; in this example, it would be a 2-year fixed rate mortgage.

To calculate the IRD, BMO would find the difference between the old posted rate for a 5-year fixed rate mortgage (5.49%) and today’s posted rate for a 2-year fixed rate mortgage (3.04%), and multiply it by the remaining balance of your mortgage to determine how much interest they’d be losing by letting you break your mortgage term early.

In this example, because you had a fixed rate mortgage, BMO would charge you the greater of three months’ interest or the interest rate differential (IRD). Since we know three months’ interest was only \$1,688, you would have to pay the IRD of \$14,088.

### Other BMO Penalty Fees

While our mortgage penalty calculator gives you a good estimate of what you’ll have to pay to break your mortgage term early, there may be other fees involved as well. One is a discharge fee, which we’ve included in our calculator. As outlined in the chart below, it varies from province-to-province. Because we used Alberta in our example, there was no discharge fee in our examples above. There may also be a registration fee, depending on which province you live in.

*Note: In Quebec, you pay all other fees through a notary, rather than through your lender. In fact, it’s important for all homebuyers to know that you may have to pay a notary or real estate lawyer to complete this entire transaction (so you should also budget for legal fees).

## The bottom line

Breaking your mortgage with BMO can be a daunting and sometimes expensive exercise. However, it can often be worth it to refinance your mortgage with a lower rate, or to access other mortgage features that you may need. No matter what you do, you’ll want as much information as possible up front. You’re on the right site to learn more about the mortgage refinance process, but don’t be scared to get in touch with a mortgage broker for advice – consultations are free, so you have nothing to lose.
