Fixed or Variable Mortgage: Which Should I Choose?
There is no single right answer for everyone. A fixed mortgage provides more certainty, while a variable mortgage gives you more exposure to changes in interest rates. The right choice depends on your cash flow, risk tolerance, plans during the term and the actual mortgage products available.

The better mortgage is the one whose payment risk, penalties and flexibility fit what you are likely to need during the term. That can matter more than a small difference in the starting interest rate.
Fixed Gives You Certainty
With a fixed-rate mortgage, the interest rate is set for the term, giving you predictable borrowing costs and greater payment certainty.
Variable Rates Can Change
A variable mortgage rate moves with the lender's prime rate, so your borrowing cost can rise or fall during the term.
Cash-Flow Tolerance Matters
If your monthly budget is tight, knowing exactly what your mortgage will cost may be more important than taking additional rate risk.
Your Risk Tolerance Matters
If changing rates will cause you constant concern, the certainty of a fixed mortgage may have real value even if another option starts slightly lower.
Penalties Matter
The cost of breaking a mortgage can differ significantly between products and can matter if you sell, refinance or change lenders during the term.
Flexibility Matters
If there is a realistic chance your plans will change, the mortgage's prepayment and portability terms deserve as much attention as the rate.
The Real Difference Is How Much Interest-Rate Risk You Want to Carry.
A fixed mortgage transfers more of the short-term rate risk away from you in exchange for certainty during the term. A variable mortgage leaves you exposed to changes in the lender's prime rate.
Neither structure is automatically better. The decision should reflect how comfortably you could handle changes in borrowing costs and how much certainty you value.
Your contractual interest rate remains fixed for the mortgage term.
Your mortgage rate can move when the lender's prime rate changes.
Borrowers who value predictable mortgage costs may prefer the certainty of a fixed structure.
Borrowers choosing variable need to be comfortable with the possibility that their borrowing cost may increase during the term.
What Happens If You Need to Break the Mortgage?
Many homeowners choose a mortgage assuming they will keep it until maturity. Life does not always cooperate. Selling, moving, refinancing or accessing equity can all require the mortgage to be changed before the term ends.
Fixed-Mortgage Penalties
Depending on the lender and mortgage terms, breaking a fixed mortgage can result in a substantial prepayment charge.
Variable-Mortgage Penalties
Variable mortgages commonly use a different prepayment-penalty structure, which should be reviewed before choosing the product.
Planning to Move
If you may sell or buy another property during the term, portability and early-payout provisions can materially affect the true cost of the mortgage.
Planning to Refinance
If you expect to access equity or restructure debt, a restrictive mortgage can become expensive even if its original rate looked attractive.
Term Length Is a Separate Decision
Choosing fixed or variable is not the same decision as choosing how long the mortgage term should be. Both need to fit your plans.
Do Not Try to Perfectly Predict Rates
No one knows with certainty where interest rates will be several years from now. Choose a structure you can live with if the forecast is wrong.
Choose the Mortgage Structure That Fits Your Life — Not a Rate Prediction.
Fixed provides greater certainty. Variable exposes you to more rate movement. The right choice depends on your cash flow, tolerance for changing rates, potential plans to sell or refinance, and the penalties and flexibility built into the actual mortgage being offered.
