Should You Break Your Mortgage Now That Rates Are Dropping? Here’s What to Know

If you locked into a fixed mortgage rate in 2022 or 2023… well, let’s just say you’re probably not feeling thrilled these days. Fixed rates have been steadily sliding since last fall, with some five-year rates dipping as low as 3.79% by the end of November. And yes — that’s significantly lower than what many homeowners signed on for.

So the million-dollar question (or at least the several-hundred-thousand-dollar one) is this:
Is it worth breaking your mortgage to snag a lower rate?

The short answer? Maybe.
The longer answer? It depends entirely on the math… and the math can get spicy.

Breaking Your Mortgage: The Basics

Even if you’re in a fixed-rate mortgage, you can break your term early and refinance at a lower rate. But there’s a catch: it comes with penalties — sometimes hefty ones.

Before you go dreaming about lower monthly payments, start with these two key questions:

1. Is your mortgage fixed or variable?
2. Is it open or closed?

If you happen to have an open mortgage, you can usually break it without a penalty (lucky you). But most Canadians are in closed mortgage terms — and that’s where the big penalty conversation begins.

According to Victor Tran, mortgage expert at Rates.ca, those penalties vary based on your mortgage type, how much time is left in your term, and the difference between your current rate and the new one you want. For fixed mortgages, the lender typically charges the higher of:

• Three months’ interest, or
• The interest rate differential (IRD) — a notoriously finicky calculation.

And no, the IRD is not friendly. As Dan Eisner of True North Mortgage puts it, “these IRD penalties can be pretty brutal.”

A Real-Life Example

Let’s say you signed a five-year fixed mortgage last fall at around 6%. Totally possible at the time. If you’ve got $500,000 left on that mortgage, the penalty — based on TD’s calculator — could be close to $30,000.

Most people don’t have 30 grand stuffed in the sofa cushions, so they refinance and roll the penalty into the new mortgage. That means requalifying, possible appraisals, legal fees… all those glamorous extras.

So is it worth it? Tran says the key is comparing the cost of breaking with the amount you’d save by switching:

“If the outstanding balance of the new mortgage, at the current maturity date, is lower than the current mortgage maturity balance, by an amount greater than the penalty and fees, then yes, it is worthwhile.”

In other words: you want to hit your break-even point.

When It Is Worth It

A recent example from Eisner’s team paints a clearer picture. They helped a client break a five-year fixed mortgage at 5.99% and switch to a five-year variable at 4.45%.

Difference seems small, right?
But it saved the homeowner $359 per month — even after paying a $7,000 penalty out of pocket. The total net savings? $20,597.57.

And since they switched to a variable rate, that rate later dropped again to 3.45%, which sweetened the deal even more.

But Don’t Wait Too Long…

Some people want to wait for rates to fall further (totally understandable). But there’s a twist: as rates drop, IRD penalties rise. Or as Eisner says, it’s “a double-edged sword.”

Other Options: Blend & Extend, Blend & Increase

If the penalty feels like too much (it often is), you might still get relief from your current lender through:

• Blend and extend — you extend your term and blend your current rate with today’s lower rate.
• Blend and increase — you refinance to increase the mortgage amount, with a blended rate.

You won’t get the absolute lowest market rate, but you also won’t be handing your lender a five-figure penalty cheque. Bless.

Will This Hurt My Credit Score?

Breaking your mortgage doesn’t directly affect your credit. But if paying the penalty or fees causes financial strain or missed payments, that’s where your score can take a hit.

Timing Matters

Leah Zlatkin of LowestRates.ca compares mortgages to snowflakes — every single one is different. (And honestly, yes. Mortgage contracts are chaotic little crystals.) Some lenders even offer penalty-free windows near the start or end of a term.

Zlatkin notes:

“Some of them will start rolling those penalties or waiving those penalties as close to six months before renewal.”

Translation: It pays to read the fine print… or have someone read it for you.

So, Should You Break Your Mortgage?

If all this makes your head spin, you’re not alone. Zlatkin recommends sitting down with a mortgage professional who can run real numbers for your exact situation — not guesses, not vibes, not wishful thinking.

She compares a good mortgage broker to the Santa Claus in Miracle on 34th Street:

“Just like that Santa Claus, a good mortgage person is going to give you the best advice for your scenario because they know it’s going to lead to future referrals.”

In other words: the right expert will tell you where the best deal is — even if it’s not with them.
