This Canada mortgage refinance calculator helps you evaluate the financial impact of refinancing your mortgage. Calculate your new monthly payment based on an updated mortgage rate or see the effect of accessing home equity. You can also use our mortgage renewal calculator to compare refinancing with simply renewing at your current lender.
Refinance Mortgage Rates
Mortgage rates are a critical factor when refinancing in Canada. The rate you secure directly impacts your monthly payments and total interest costs. Explore current mortgage rates to see what is available before making a decision.
When refinancing, you are essentially taking out a new mortgage. This means you may be able to negotiate a rate that is significantly lower than your current rate, especially if market rates have dropped since you originally signed.
What Are the Reasons to Refinance?
There are several situations where refinancing your mortgage can make financial sense:
| Reason | How It Helps |
|---|---|
| Lower interest rate | Reduces monthly payments and total interest paid |
| Access home equity | Borrow up to 80% of your home’s value for renovations, debt consolidation, or investing |
| Consolidate debt | Replace high-interest credit cards or loans with a lower mortgage rate |
| Change mortgage terms | Switch from variable to fixed (or vice versa), or adjust amortization |
| Change lenders | Move to a lender offering better terms or service |
Since you are switching lenders when you refinance, the process is similar to applying for a new mortgage. Your lender will assess your ability to afford the mortgage, including your debt service ratios and the mortgage stress test, which requires qualifying at the higher of your contract rate plus 2% or 5.25%.
When Should You Refinance Your Mortgage?
Refinancing makes sense when the long-term savings outweigh the costs. Common triggers include:
Rate Reduction of 1% or More
The general rule of thumb is that refinancing becomes worthwhile when you can reduce your interest rate by at least 1 percentage point (100 basis points). At this level, the interest savings typically exceed the cost of breaking your current mortgage over a reasonable time frame.
Debt Consolidation
If you are carrying high-interest debt — such as credit cards at 19–22% or a personal loan at 10–15% — consolidating that debt into your mortgage at 4–5% can save thousands in interest. Use our debt payoff calculator to compare strategies.
Major Home Renovation
Accessing home equity through refinancing can fund major renovations that increase your property’s value. This can make more sense than a HELOC if you prefer the certainty of fixed payments.
Change in Financial Circumstances
If your income has increased significantly, you may want to refinance to a shorter amortization to pay off your mortgage faster. Conversely, if money is tight, extending the amortization can lower monthly payments.
Costs of Refinancing in Canada
Refinancing involves several costs that must be factored into your break-even analysis:
| Cost | Typical Range | Notes |
|---|---|---|
| Mortgage prepayment penalty | $1,000 – $20,000+ | Largest cost; varies by mortgage type |
| Legal fees | $500 – $1,500 | Lawyer or notary to register new mortgage |
| Appraisal fee | $300 – $500 | Lender may require a new appraisal |
| Discharge fee | $200 – $400 | Fee to remove old mortgage from title |
| Title insurance | $200 – $400 | May be required by new lender |
| Total estimated costs | $2,200 – $22,800+ |
Understanding Mortgage Prepayment Penalties
The prepayment penalty depends on your mortgage type:
| Mortgage Type | Penalty Calculation | Typical Cost |
|---|---|---|
| Variable rate | 3 months of interest | Usually $1,000 – $4,000 |
| Fixed rate | Greater of: 3 months interest OR Interest Rate Differential (IRD) | Can be $5,000 – $20,000+ |
The Interest Rate Differential (IRD) is the difference between your current mortgage rate and the rate your lender can currently charge for a mortgage with a term matching your remaining term. The IRD penalty can be substantial, especially if rates have dropped significantly. Use our mortgage penalty calculator to estimate your specific penalty.
Detailed Break-Even Analysis: Worked Example
Suppose you are 3 years into a 5-year fixed mortgage with the following details:
| Current Mortgage | Details |
|---|---|
| Remaining balance | $400,000 |
| Current rate | 5.50% |
| Monthly payment | $2,437 |
| Remaining term | 2 years |
You can refinance at 4.25% for a new 5-year term:
| Refinanced Mortgage | Details |
|---|---|
| New rate | 4.25% |
| New monthly payment | $2,144 |
| Monthly savings | $293 |
| Refinancing Costs | Amount |
|---|---|
| Prepayment penalty (IRD) | $8,500 |
| Legal fees | $1,000 |
| Appraisal | $400 |
| Discharge fee | $300 |
| Total costs | $10,200 |
Break-even point: $10,200 ÷ $293/month = 34.8 months (approximately 3 years)
Since the new mortgage term is 5 years (60 months), you would save money for approximately 25 months after reaching break-even, resulting in net savings of approximately $7,325 over the new 5-year term after accounting for all costs.
If your break-even period is longer than your planned stay in the home, refinancing may not be worthwhile.
Refinance to Lower Rate vs Refinance to Access Equity
| Feature | Rate Reduction Refinance | Equity Access Refinance |
|---|---|---|
| Goal | Lower monthly payments/interest | Access cash from home equity |
| Maximum LTV | 80% of home value | 80% of home value |
| Effect on mortgage | Lower payments, same or similar balance | Higher balance, potentially higher payments |
| Common uses | Savings on interest | Renovations, debt consolidation, investing |
| Risk | Low (if break-even is favorable) | Moderate (increasing debt secured by home) |
When accessing equity, you can borrow up to 80% of your home’s appraised value, minus your existing mortgage balance. For example, if your home is worth $700,000 and you owe $350,000, you could access up to $700,000 × 80% − $350,000 = $210,000 in equity. See our mortgage affordability calculator to evaluate how additional borrowing affects your budget.
The Refinance Process: Step by Step
- Calculate your break-even point — Use this calculator to compare costs vs savings
- Check your mortgage penalty — Contact your lender or use our mortgage penalty calculator
- Get pre-approved — Apply with new lenders and compare rates and terms
- Order an appraisal — The new lender will require an appraisal of your property
- Hire a lawyer or notary — They will handle the legal paperwork to discharge the old mortgage and register the new one
- Close the refinance — Sign the new mortgage documents, pay the penalty and fees, and your new mortgage begins
The entire process typically takes 2 to 6 weeks from application to closing.
Alternatives to Refinancing
Before refinancing, consider whether these alternatives might meet your needs at a lower cost:
| Alternative | Best For | Key Advantage |
|---|---|---|
| HELOC | Accessing equity for ongoing needs | No penalty to set up; pay interest only on what you use |
| Mortgage renewal | Getting a better rate at term end | No penalty; negotiate with current or new lender |
| Blend and extend | Mid-term rate adjustment | Blends old and new rate; avoids full penalty |
| Lump-sum prepayment | Paying down principal faster | Uses prepayment privileges without penalty |
