Thinking About Switching from a Variable to a Fixed Mortgage? Read This First

If you have a variable rate mortgage and recent economic headlines are making you consider locking into a fixed rate, it’s important to understand what that decision actually means—both now and down the road.

In most cases, switching from a variable to a fixed rate will:

• Increase the interest rate you pay for the rest of your term
• Reduce flexibility
• Potentially expose you to much higher penalties if you need to break the mortgage early

While each lender handles the conversion slightly differently, the overall trade-offs are fairly consistent.

Fixed vs. Variable: Understanding the Interest Rate Difference

Fixed-rate mortgages almost always come with higher interest rates than variable-rate mortgages. That’s one of the main reasons borrowers choose variable in the first place—to benefit from a lower rate.

Fixed rates feel “safe” because the payment doesn’t change, while variable rates feel “uncertain” because they move with prime. However, variable rates are not unpredictable in the way many people fear.

The Bank of Canada has eight scheduled rate announcements per year, and rate changes typically move in increments of 0.25%. This structure prevents sudden, extreme changes. Your variable rate cannot double overnight.

Mortgage Penalties: Where the Real Difference Shows Up

Penalties are often the most misunderstood part of this decision.

While every lender calculates penalties differently, the general rule of thumb is:

• Variable-rate mortgage:
  Roughly three months’ interest, or about 0.5% of the mortgage balance
• Fixed-rate mortgage:
  Can be significantly higher due to the interest rate differential (IRD)—sometimes 3–4% or more of the mortgage balance

Example

On a $500,000 mortgage:

• Variable-rate penalty: approximately $2,500
• Fixed-rate penalty: could be $15,000–$20,000 or more, depending on the lender

This difference alone is why many borrowers choose variable—even if they eventually plan to convert.

Why Flexibility Matters More Than People Expect

Statistics show that nearly 60% of Canadians break their mortgage before the end of the term, with the average break happening around 38 months.

Even with the best intentions, life changes. Common reasons people break their mortgage include:

• Job relocation
• Buying a new home
• Accessing equity
• Debt consolidation
• Starting or funding a business
• Marriage or combining households
• Divorce or separation
• Illness or caregiving needs
• Job loss or job change
• Removing someone from title
• Paying off the mortgage early

Locking into a fixed rate means giving up some of that flexibility—and accepting the possibility of much higher costs if plans change.

The Real Trade-Off

Switching from variable to fixed is essentially a decision to:

• Pay more interest now
• In exchange for payment certainty
• While accepting higher risk if you need to make changes later

For some borrowers, that trade-off makes sense. For others, it doesn’t. There’s no universal answer—only what aligns best with your financial situation, risk tolerance, and future plans.

Final Thoughts

Before locking in, it’s worth slowing down and looking beyond today’s headlines. Rates matter—but so do flexibility, penalties, and the likelihood that your plans may change.
