Fixed vs. Variable Mortgage: Which Is Better in Canada?
Quick Answer
Fixed vs. Variable Mortgage: Which Is Better in Canada?
Fixed mortgages offer rate certainty and protection from increases, while variable mortgages historically cost less over the long term but carry payment fluctuation risk. Variable rates typically outperform fixed when the Bank of Canada is cutting rates; fixed is preferable when rates are rising or for budget certainty. Your choice depends on risk tolerance and rate outlook.
Detailed Explanation
Fixed vs. Variable Mortgages in Canada
Fixed-Rate Mortgages
With a fixed-rate mortgage, your interest rate stays the same for the entire term (typically 1 to 5 years). Your monthly payment remains constant regardless of market changes.
Pros:
- Payment certainty for budgeting
- Protection against rate increases
- No risk of payment shock
- Easier to qualify (lenders prefer predictable payments)
Cons:
- Typically higher initial rate than variable
- Breaking a fixed mortgage early can be expensive (IRD penalty)
- No benefit when rates drop
Variable-Rate Mortgages
With a variable-rate mortgage, your interest rate fluctuates with the lender's prime rate, which tracks the Bank of Canada's overnight rate.
Pros:
- Historically lower rates than fixed (typically 0.5 to 1.0% less)
- Potential savings when rates fall
- Lower penalty to break early (typically 3 months' interest)
- Rate can drop without refinancing
Cons:
- Payment uncertainty (rates can rise)
- Risk of payment shock during rate increases
- Psychological stress of fluctuating payments
Historical Performance
A Bank of Canada study found that variable-rate mortgages cost less than fixed-rate mortgages approximately 80 to 90% of the time over a 10-year period. However, this doesn't account for rate hike cycles where variable borrowers saw significant increases.
When to Choose Fixed
- You expect rates to rise
- You need budget certainty
- You plan to stay in the home long-term
- You're risk-averse
- Rates are historically low
When to Choose Variable
- You expect rates to fall or stay stable
- You can absorb payment increases
- You may sell or refinance soon
- The spread between fixed and variable is significant (>0.5%)
How It Is Calculated
How to Compare Fixed vs. Variable
Step 1: Get Rate Quotes
Obtain current rates from multiple lenders:
- 5-year fixed: e.g., 4.79%
- 5-year variable: e.g., 5.10% (prime - 0.35%)
Step 2: Calculate Monthly Payments
For a $500,000 mortgage, 25-year amortization:
Fixed at 4.79%:
- Monthly payment: ~$2,845
- Total interest over 5 years: ~$114,700
Variable at 5.10% (if rates stay flat):
- Monthly payment: ~$2,948
- Total interest over 5 years: ~$122,900
Step 3: Factor in Rate Scenarios
| Scenario | Fixed Total Cost | Variable Total Cost |
|---|---|---|
| Rates stay flat | $170,700 | $177,900 |
| Rates drop 1% | $170,700 | $164,200 |
| Rates rise 1% | $170,700 | $191,600 |
Step 4: Consider Penalties
- Fixed mortgage break penalty: Interest Rate Differential (IRD) — can be $10,000 to $30,000+
- Variable mortgage break penalty: 3 months' interest — typically $3,000 to $8,000
Example
Example: $500,000 Mortgage Comparison
Scenario: Borrower choosing between 5-year fixed (4.79%) and 5-year variable (prime - 0.35%, currently 5.10%).
| Factor | 5-Year Fixed | 5-Year Variable |
|---|---|---|
| Starting rate | 4.79% | 5.10% |
| Monthly payment | $2,845 | $2,948 |
| Rate after 2 years (rates drop 1%) | 4.79% | 4.10% |
| Monthly payment after drop | $2,845 | $2,565 |
| Total paid over 5 years | ~$170,700 | ~$167,200 (if rates drop) |
| Break penalty (if selling year 3) | ~$15,000 IRD | ~$7,200 (3 months interest) |
Decision factors:
- If the Bank of Canada is in a rate-cutting cycle, variable can save money
- If you may sell before 5 years, variable's lower penalty is advantageous
- If you need absolute payment certainty, choose fixed
- The break-even point: variable needs rates to drop by ~0.5% within 2 years to beat fixed
