Fixed vs Variable Mortgage in Canada 2026: Real Math

If you’ve spent any time on Reddit or talking to your bank lately, you’ve heard strong opinions on both sides of the fixed vs variable debate. The truth is there’s no universally correct answer — it depends on your income stability, risk tolerance, and how long you plan to stay in the home. Let’s run the actual numbers so you can make a decision that fits your situation rather than your mortgage broker’s commission structure.

Where Rates Actually Sit Right Now (2026)

The Bank of Canada has moved rates considerably over the past few years. After the aggressive hiking cycle and subsequent cuts, here’s roughly where you’ll find posted and discounted rates as of early 2026:

Mortgage Type	Typical Range (Big 6 Banks)	Broker/Monoline Range	Best Available (Insured)
5-Year Fixed	4.89% – 5.49%	4.39% – 4.74%	~4.29%
3-Year Fixed	4.69% – 5.19%	4.19% – 4.59%	~4.14%
Variable Rate (VRM)	Prime – 0.50% to Prime – 0.85%	Prime – 0.85% to Prime – 1.10%	~Prime – 1.00%
Adjustable Rate (ARM)	Prime – 0.50% to Prime – 0.80%	Prime – 0.80% to Prime – 1.05%	~Prime – 0.95%

Note: Prime Rate is currently 5.20% as of early 2026. Variable rates above translate to roughly 4.10%–4.70% depending on your discount. These numbers shift — always verify directly with lenders or a broker before making any decisions.

What’s the Actual Difference in Monthly Payments?

Let’s use a concrete example most Canadian buyers can relate to: a $600,000 home, 20% down ($120,000), leaving a $480,000 mortgage amortized over 25 years.

Scenario	Rate	Monthly Payment	Total Interest (5 Years)	Balance Remaining (5 Years)
5-Year Fixed (broker rate)	4.49%	$2,629	$99,860	$422,480
Variable (Prime – 1.00%)	4.20% today	$2,573	Depends on rate path	Depends on rate path
If variable stays flat 5 years	4.20%	$2,573	$93,240	$420,150
If variable rises 100 bps by Year 2	Blended ~4.80%	$2,573–$2,720	~$103,500	~$424,200

The monthly savings starting out on variable are real but modest — around $56/month compared to a competitive fixed rate. Over five years with rates staying put, that’s roughly $6,600 in savings. Not nothing, but not life-changing either. The math shifts dramatically if rates move 75–100 basis points in either direction.

Breaking Down the Two Types of Variable

One thing that burned a lot of borrowers in 2022–2023 was confusion about what kind of variable rate they had. There’s an important distinction:

• Variable Rate Mortgage (VRM): Your payment stays the same when prime moves, but the split between principal and interest changes. If rates rise enough, you can hit a “trigger rate” where your payment no longer covers interest at all. Several major banks have VRM products.
• Adjustable Rate Mortgage (ARM): Your payment actually changes with prime. No trigger rate surprise, but you feel every Bank of Canada announcement in your bank account.

If you choose variable, understanding which product you have matters. Most monoline lenders offer ARMs. Many big banks offer VRMs. Ask explicitly.

The Penalty Problem: Fixed Rates Have a Catch

Here’s where fixed rates can become genuinely painful. If you need to break your mortgage early — job loss, divorce, upsizing, downsizing, relocation — the penalty on a fixed rate can be brutal.

Situation	Fixed Rate Penalty	Variable Rate Penalty
Breaking 2 years into 5-year term	IRD: Often $15,000–$30,000+ on a $480K mortgage	3 months interest: ~$4,800–$6,000
Breaking 1 year into 5-year term	IRD: Can exceed $20,000 when rates have fallen	3 months interest: ~$5,000
At renewal (end of term)	No penalty	No penalty

The Interest Rate Differential (IRD) is calculated using the bank’s posted rates versus your contract rate, and each lender calculates it differently. Some bank IRD formulas are notoriously punishing. Monoline lenders and credit unions often use simpler, cheaper-to-break calculations. Always ask your lender to show you their penalty calculation method before signing.

If there’s a real chance you’ll move or refinance within your term, a variable rate’s predictable three-month interest penalty can save you a very significant amount of money.

Historical Context: What Has Actually Happened

Studies of Canadian mortgage data going back to the 1980s have generally shown that variable rate borrowers pay less over time — largely because variable rates track the overnight rate, which tends to average lower than the fixed premium borrowers pay for certainty. The most-cited research suggests variable rate borrowers have come out ahead roughly two-thirds of the time over rolling five-year periods.

But 2022 was a stark reminder that “most of the time” isn’t “all of the time.” Borrowers who took variable in 2021 at historic lows watched their rates climb from around 1.45% to over 6.70% within 18 months. Mortgage payments on adjustable products went up by hundreds of dollars per month. Some borrowers on VRM products hit trigger rates and had their amortization effectively extended.

The lesson isn’t that variable is bad — it’s that variable requires financial flexibility and a genuine ability to absorb higher payments without serious strain.

When to Pick Fixed

• Your budget is tight: If you’re at or near your stress test limit, payment certainty isn’t just comfort — it’s financial safety. A 150 bps rate increase on a variable ARM could add $350–$500/month on a $480K mortgage.
• You’re a first-time buyer: Owning a home brings enough surprises. Removing payment variability gives you time to get your footing and build an emergency fund.
• Your income is variable: Freelancers, commission-based workers, and business owners already manage income uncertainty. Adding payment uncertainty on top of that is a stressful combination.
• You’re confident you’ll stay for the full term: If you’re putting down roots and have no realistic reason to break early, you capture the certainty of fixed without worrying about the penalty trap.
• The rate gap is small: When fixed and variable rates are within 25–30 basis points of each other, the math barely favours variable and the certainty of fixed becomes the obvious trade-off.

When to Pick Variable

• You have a genuine cash buffer: If you have 3–6 months of expenses sitting in a HISA or TFSA and could absorb a $400–$500/month payment increase without real hardship, you’re actually positioned to take on rate risk.
• Your life situation might change: Expecting a job transfer, planning to upsize in 2–3 years, or in a relationship situation that’s in flux? The lower penalty on variable could save you thousands if you need to exit early.
• The rate gap is meaningful: When variable rates are 50–80+ basis points below fixed, that’s a real starting advantage. Rates would need to rise and stay elevated for variable to underperform.
• You understand what you’re signing: This sounds obvious, but many people took variable in 2021 without genuinely stress-testing what their payments would look like at 5%, 6%, or 7%. If you can clearly answer “what’s my payment if prime goes to 7%?” and the answer doesn’t terrify you, you’re a reasonable variable candidate.

The 3-Year Fixed: The Option People Overlook

With rates sitting in an interesting spot right now — somewhat elevated versus historic averages but with potential movement in either direction — a 3-year fixed has genuine appeal that gets underappreciated in the fixed vs variable conversation. You get payment certainty without locking in for five full years. If rates move materially lower, you’re back at the table in 36 months rather than 60. The rate premium over a 5-year fixed is often modest (sometimes as little as 10–20 bps), and the penalty to break is calculated over a shorter remaining term, so it’s less catastrophic.

It’s not always the right call, but it’s worth including in your comparison when you’re shopping.

Quick Decision Framework

Your Situation	Likely Better Fit
Tight budget, first home, salaried job	5-Year Fixed
Solid buffer, stable high income, flexible life plans	Variable (ARM)
May move or refinance within 3–4 years	Variable or 3-Year Fixed
Rate gap between fixed/variable is under 30 bps	Fixed (certainty wins when math is close)
Rate gap is 60+ bps in favour of variable	Variable worth serious consideration
Self-employed or commission income	Fixed (reduce variables you can control)

The Bottom Line

There is no correct answer that works for every Canadian borrower in 2026. The rate environment has normalized from the extremes of 2021 lows and 2023 highs, and the gap between fixed and variable is real but not enormous. Fixed gives you certainty and protection from a bad rate cycle. Variable gives you flexibility on penalties and a shot at lower total interest if rates cooperate.

What actually matters most: stress-test yourself honestly at prime + 2%, talk to a mortgage broker who isn’t pushing one product, and read the prepayment and penalty terms before you sign anything. The rate you negotiate matters, but so does the fine print that determines what it costs you to change your mind.
