Should You Break Your Mortgage Early? Here's How I Would Look at It

Published 14 September 2026

One of the questions I'm hearing more often right now is: "Rates have changed. Should I break my mortgage and get into something better?"

It's a fair question, and sometimes the answer is absolutely yes. But after more than two decades of working with mortgages and financial planning, I can tell you that the interest rate is only one part of the decision. When I review this for a client, I'm really trying to answer a much more important question: does making a change today leave you in a better financial position overall?

First, find out what it would actually cost to leave

An open mortgage lets you break the contract without a prepayment penalty. With a closed mortgage there will normally be a penalty, commonly calculated as the greater of three months' interest or an interest rate differential, depending on the mortgage and the lender.

This is where homeowners get into trouble relying on something they saw online. Two people can owe the same amount and have completely different penalties, because their lenders, original rates, discounts and remaining terms are different. The differential is built from rates your own contract names, and it typically comes up where your contract rate is higher than the current rate.

In my office we have software that models the potential penalty, so we know whether it's even worth exploring. But before anyone makes a move, I want the lender's current payout and penalty figure in writing. That is the number we make the decision around.

But the penalty isn't really the question

Someone will tell me what their lender quoted and ask whether that's bad. My answer is: I don't know yet. What are we getting for it?

If a change covers its own costs and more, improves your cash flow, lets us restructure expensive debt, gives you access to equity, or puts you into a mortgage that better fits where your life is headed, paying a penalty can make perfect sense. On the other hand, you could have a relatively modest penalty and I may still tell you not to touch the mortgage.

There can also be discharge, administration, appraisal, reinvestment or setup costs, and in some situations cash back from the original mortgage has to be repaid.

And there's something else to watch: a lower payment isn't necessarily the same thing as saving money. If your payment falls because we've stretched the remaining balance over a longer amortization, your cash flow may improve while your total interest cost goes up. That's why I don't like looking at mortgage decisions in isolation.

Sometimes the best advice is to do nothing

There's a tendency to assume that if a mortgage can be changed, it should be changed. I don't agree.

Sometimes I'll run the numbers and say, "You're positioned very well. Leave this alone." Maybe you're close to renewal. Maybe the penalty wipes out most of the potential benefit. Maybe you're planning to sell, or your existing mortgage has features that are valuable to you.

There may also be alternatives to breaking the mortgage outright. If you're buying a new home, ask whether you can port it and take your existing rate and terms with you. Making full use of your prepayment privileges each year brings future penalties down, because they're calculated on a lower balance. And a blend-and-extend may avoid the penalty altogether, though administrative fees can still apply. All of it depends on your lender and your terms.

The goal isn't to manufacture a transaction. The goal is to make a good financial decision.

This is also why I believe mortgages should be reviewed every year

This is probably the biggest piece of advice I'd give homeowners. Don't take a five-year mortgage and put it in a drawer for five years.

Your mortgage is likely the largest financial commitment you'll ever have, and a lot can change during a term: rates, property values, your income, your debt, your family, your plans to move.

At least once a year, your mortgage should get a quick financial checkup. We should know where the balance stands, how much time is left in the term, what your prepayment privileges are, roughly what it would cost to leave, and, most importantly, whether the mortgage is still structured properly for what you're trying to accomplish.

Your annual statement carries a lot of this already, particularly with a federally regulated lender — your privileges, how a penalty is calculated, your balance and rate. But receiving a statement isn't the same thing as having somebody actually review the mortgage with you. That's the difference I think matters.

So, should you break your mortgage?

Maybe. But don't decide because you saw a lower rate advertised, or because someone on social media said now is the time. Have somebody run your numbers. Find out what your lender will actually charge. Look at what's left after all the costs, and how long you're likely to keep the mortgage. Then look at it as part of your overall financial picture.

This is a different question from moving to a new lender at renewal. Everything here is about ending a term early, with time still to run.

And don't be disappointed if the conclusion is "don't do anything." Sometimes that's the best mortgage advice I can give.

If you're in Burlington, Hamilton, Waterdown or Oakville, or throughout the Niagara region, and you're wondering whether your current mortgage is still positioned properly, I'm happy to review it with you. You don't need to be at renewal to have that conversation.

Related questions

Can I find out my penalty before I commit to anything?

Yes, and it works best in two steps. Before you decide anything, an estimate run against your mortgage details tells you roughly what scale you're dealing with. Then, when you're actually considering prepaying, a federally regulated lender gives you the real number: the penalty, how it was calculated, and how long that amount holds. Asking isn't a commitment to go ahead, and the lender's figure is the one you act on.

What is the interest rate differential?

It compares the interest left on your current term at your contract rate against the interest at a comparison rate. Your lender may use the posted rate at signing or your discounted rate, and either the current posted rate for a similar term or that rate less your original discount. Your contract says which pairing applies. It typically comes up where your contract rate is higher than the current rate and you signed less than five years ago.

Is the penalty the only cost of breaking a mortgage?

Not necessarily. Breaking a closed contract can also bring administration fees, appraisal fees, reinvestment fees, a discharge fee to remove the existing charge and register a new one, and repayment of any cash back you received on the original mortgage. An estimate of the penalty won't cover those, so ask your lender to list every fee that would apply to your file.

Is there a way to avoid the penalty altogether?

Sometimes. If you're buying a new home, ask whether you can port your mortgage and take your existing rate, terms and conditions with you. Using your prepayment privileges each year brings future penalties down, because they're worked out on a lower balance. A blend-and-extend may avoid the penalty too, though administrative fees can still apply. Whether any of these are open to you depends on your lender and your contract.
