Fixed vs. Variable: What Matters Right Now?

“Should I go fixed or variable?”

It’s one of the most common mortgage questions—and one of the hardest to answer with a simple rule.

It can be tempting to look at today's rates, make a prediction about where interest rates are headed and choose whichever mortgage appears most likely to cost less.

But that misses an important part of the decision.

The right mortgage isn't necessarily the one that ultimately has the lowest rate. It's the one that fits your budget, your tolerance for uncertainty and what you expect to happen in your life during the mortgage term.

Fixed: The Value of Certainty

With a fixed-rate mortgage, your interest rate is set for the term of the mortgage.

For many homeowners, the biggest advantage is predictability. You know what rate you're paying and, with a typical fixed-payment mortgage, what your regular principal-and-interest payment will be.

That can be particularly valuable if your household budget doesn't have much room for fluctuation or if you simply prefer knowing exactly what to expect.

The trade-off is flexibility.

Depending on the lender and mortgage product, breaking a closed fixed-rate mortgage before the end of the term can result in a significant prepayment penalty. The calculation can involve the greater of three months' interest or an Interest Rate Differential (IRD), subject to the terms of the mortgage.

That matters because life doesn't always cooperate with a five-year plan.

You might sell your home, relocate, refinance, separate, combine households or want to access equity before your mortgage term is finished.

That's why the question shouldn't only be, “What's the fixed rate?”

It should also be, “What happens if my plans change?”

Variable: Flexibility With Uncertainty

Variable-rate mortgages generally move in relation to the lender's prime rate, which is influenced by changes in the Bank of Canada's policy rate.

That means your borrowing cost can rise or fall during the term.

Depending on the mortgage product, a change in rates may alter your payment or change how much of a fixed payment goes toward principal versus interest.

Understanding exactly how a particular variable mortgage works is important before choosing it.

The obvious trade-off is uncertainty.

If rates rise, you need to be financially—and psychologically—comfortable with the consequences.

But variable mortgages can offer another consideration: the cost of breaking the mortgage.

Many closed variable-rate mortgages use a penalty based on approximately three months' interest, although the exact calculation depends on the lender and mortgage contract. That can make variable mortgages attractive to borrowers who place a high value on flexibility.

Again, the rate is only part of the decision.

Penalties Deserve More Attention

Mortgage penalties aren't particularly exciting when you're choosing a mortgage.

They become considerably more interesting when you're writing a cheque to get out of one.

This is one reason comparing mortgages based solely on rate can be misleading.

Two lenders could offer similar fixed rates while having very different approaches to prepayment privileges, portability and penalty calculations.

A slightly lower rate isn't necessarily the better deal if the mortgage becomes expensive or restrictive when your circumstances change.

Before choosing a mortgage, it's worth asking:

How is the penalty calculated if I need to leave early?

That's especially important if there's a reasonable possibility you'll sell, refinance or make another major financial change during the term.

Your Risk Tolerance Matters

There is also a personal component to the fixed-versus-variable decision that can't be captured in a rate chart.

Imagine your variable mortgage becomes more expensive after rates rise.

Would you think:

“That's okay. I understood this could happen and my budget can handle it.”

Or would you spend the next six months checking interest-rate announcements and worrying about your payment?

That distinction matters.

Someone with substantial monthly cash flow and a high tolerance for rate fluctuations may be perfectly comfortable with variable.

Someone with a tighter budget—or who simply values certainty—may be happier paying for the predictability of a fixed rate.

Neither approach is inherently better.

Think About the Next Few Years

Before deciding between fixed and variable, consider what your life might realistically look like during the mortgage term.

Are you likely to stay in the property?

Could a job change or relocation happen?

Are you planning renovations?

Could you need to refinance?

Are you expecting your household income to change?

Might you purchase another property?

The answers can influence which mortgage structure makes sense just as much as today's interest rate.

You don't need to know exactly what the next several years will bring. Few people do.

But you should choose a mortgage that gives you an appropriate combination of cost, stability and flexibility for the possibilities you can reasonably anticipate.

Don't Build Your Mortgage Around a Rate Prediction

No one knows with certainty what interest rates will do throughout an entire mortgage term.

Trying to choose the “winner” between fixed and variable based solely on a forecast can turn an important financial decision into a bet on the market.

A better approach is to ask:

What happens if rates rise?

What happens if rates fall?

What happens if I need to break this mortgage?

And which of those scenarios am I most comfortable living with?

That's mortgage strategy.

Fixed or Variable? Start With You.

There isn't one mortgage structure that's right for everyone.

The goal is to understand the trade-offs and choose an option that fits your finances, your plans and your comfort level—not simply whichever rate looks most attractive today.
