Fixed vs Variable Mortgage Rate: Compare Your Options

Choosing between a fixed and variable mortgage rate involves weighing payment certainty against potential interest savings. Fixed rates lock in your payment for the term, shielding you from market increases but possibly costing more if rates fall. Variable rates fluctuate with the lender's prime rate, offering lower initial payments and savings if rates drop, but requiring budget flexibility for possible increases. Your choice depends on your risk tolerance, financial stability, and outlook on interest rate movements — we help you assess which aligns with your situation using current qualifying rules and stress test considerations.

How Fixed and Variable Rates Work in Practice

With a fixed rate mortgage, your interest rate and monthly payment remain unchanged for the entire term, typically ranging from six months to ten years. This predictability simplifies budgeting, especially for first-time buyers or those with fixed incomes. The rate is set based on bond yields at the time of signing, not the Bank of Canada's overnight rate directly.

Variable rate mortgages tie to the lender's prime rate, which moves with the Bank of Canada's policy interest rate. Your payment might stay constant while the interest portion changes (trigger rate concept), or your payment could adjust with prime. Most variable rates offer a discount or premium to prime, expressed as prime minus or plus a percentage.

Both types require passing the mortgage stress test, which uses the higher of the Bank of Canada's benchmark rate or your contract rate plus two percentage points. This ensures you could afford payments if rates rose significantly at renewal.

Comparison Table: Key Differences at a Glance

The table below outlines core distinctions to help you visualize trade-offs. Fixed rates provide term-long payment certainty, ideal when rates are low or expected to rise. Variable rates often start lower and can save money over time if rates decline or stay flat, but expose you to payment uncertainty if prime increases.

Consider renewal timing: fixed rates renew at prevailing market rates, while variable rates convert to the current prime-based product at term end. Penalties for breaking a fixed rate term are usually the greater of three months' interest or interest rate differential (IRD), which can be substantial. Variable rate penalties are typically just three months' interest, offering more flexibility if you anticipate moving or refinancing soon.

For self-employed applicants, both rate types require similar documentation — two years of averaged income with possible add-backs — but the choice impacts how qualifying income is stress-tested. Newcomers to Canada can access both fixed and variable options through newcomer programs at major lenders, subject to standard down payment and credit requirements.

Which Should You Choose? Decision Framework

Start by assessing your cash flow sensitivity. If a 1-2% increase in your mortgage payment would strain your budget, the stability of a fixed rate may be worth the potential opportunity cost. Conversely, if you have emergency savings, a stable income, and could absorb higher payments, a variable rate might offer savings over the long term.

Evaluate your timeline. If you plan to sell or refinance within three years, the lower penalty flexibility of a variable rate often outweighs rate risk. For longer holds — seven years or more — historical data shows variable rates have frequently outperformed fixed, though past performance doesn't guarantee future results, especially in volatile markets.

Consider your mortgage goals. Are you prioritizing rate minimization, payment predictability, or flexibility for extra payments? Variable rates often allow easier prepayment privileges without penalty, while some fixed rates restrict lump-sum payments.

Common Comparison Questions Answered

Many clients ask whether they can switch from variable to fixed during the term. Yes, most lenders allow locking into a fixed rate at any time, usually at the current fixed rate for your remaining term. This provides a safety net if rates start rising after you chose variable.

Another frequent question involves conversion fees. Switching from variable to fixed mid-term typically incurs no penalty, but you accept the fixed rate available on that conversion date — which could be higher than your original variable rate. Always confirm the terms with your lender before proceeding.

Lastly, borrowers wonder how often variable rates change. While the Bank of Canada meets eight times yearly, lenders may adjust prime immediately or with a lag. Your mortgage contract specifies how and when your rate responds to prime shifts — review this carefully to understand your exposure.

What is the trigger rate on a variable mortgage?

The trigger rate is the interest rate at which your monthly payment no longer covers the interest portion of your loan, causing your balance to rise despite regular payments. It depends on your payment amount, original loan size, and the lender's prime rate formula. If prime rises above this threshold, you must increase your payment, make a lump sum payment, or switch to a fixed rate to avoid negative amortization.

Can I get a variable rate mortgage as a first-time buyer?

Yes, first-time home buyers in BC qualify for both fixed and variable rate mortgages subject to standard lending criteria. You'll need to pass the stress test, meet down payment requirements (as low as 5% with CMHC insurance for homes under $1M), and demonstrate sufficient income and credit history. Many first-time buyers choose variable rates for initial savings, but we review your budget resilience to ensure suitability.

How does the stress test apply differently to fixed vs variable?

The stress test uses the same calculation for both rate types: you must qualify at the higher of the Bank of Canada's benchmark rate or your contract rate plus two percentage points. For variable mortgages, the "contract rate" is the current discounted prime rate. This means you qualify based on a hypothetical higher payment, ensuring affordability if rates increase significantly during your term.

Is it better to lock in a fixed rate when rates are low?

Locking in a fixed rate during low-rate periods can provide long-term payment certainty, especially if you believe rates will rise over your term. However, "low" is relative — rates today may not stay low, and variable rates could still save money if the downward trend continues or rates stagnate. We help you weigh term length, penalty flexibility, and your financial comfort with uncertainty to make an informed choice.
