Thinking about refinancing your mortgage? You’re not alone. In 2026, hundreds of thousands of Canadians are looking at their mortgage statements and asking the same question — is it worth breaking my current deal to get a better rate?
And the honest answer is: it depends on your numbers. That’s exactly what this calculator is here for.
Plug in your current mortgage balance, your existing rate, how much time is left on your term, and the new rate you’re being offered. Our calculator will show you your break penalty (using the correct Canadian IRD formula), your new monthly payment, how much you save each month, and the exact number of months before you break even.
So instead of guessing, you’ll know — in about 60 seconds.
What Is Mortgage Refinancing in Canada?
Refinancing your mortgage means replacing your current mortgage with a brand new one. You’re basically starting fresh — with a new lender (or the same one), a new rate, and new terms.
But here’s the thing. You’re breaking a legal contract early. And that costs money — in the form of a prepayment penalty. The penalty can be small or it can be shockingly large, depending on your lender and how much time is left on your term.
There are three main reasons Canadians refinance:
1. To get a lower interest rate. If rates have dropped since you locked in, you could save hundreds of dollars a month by switching. Look, even a 1% rate drop on a $500,000 mortgage saves you roughly $250/month. That adds up fast.
2. To access your home equity. You can pull cash out of your home — up to 80% of its value — to pay for renovations, education, or other big expenses. Plus, the interest rate on that money is far lower than a personal loan or credit card.
3. To consolidate high-interest debt. Rolling a $30,000 credit card balance (at 19.99%) into your mortgage (at 4–5%) can cut your interest costs dramatically. It’s one of the most powerful things a homeowner can do to get ahead financially.
How to Use This Mortgage Refinance Calculator
Using this tool is simple. Here’s what each section means.
Current Mortgage Details
Start by entering what you’ve got right now.
- Home Value — Your best estimate of what your home is worth today. Not sure? Check a site like Zolo or Realtor.ca for nearby listings.
- Remaining Mortgage Balance — The amount you still owe, not the original amount you borrowed.
- Current Interest Rate — You’ll find this on your mortgage statement or renewal letter.
- Rate Type (Fixed or Variable) — This matters because it changes how your penalty is calculated. Fixed-rate penalties are usually much higher than variable-rate ones.
- Remaining Amortization — How many years are left in total on your mortgage.
- Months Left in Your Current Term — Your term is the contract period (e.g., 5 years). How many months are left before it naturally expires?
New Mortgage Terms
This is what you’re considering switching to.
- New Interest Rate — The rate you’ve been quoted by a new lender, or what you’re seeing advertised.
- New Amortization — You can keep it the same or extend it. Extending lowers your monthly payment but means more interest paid over time.
H3: Refinancing Costs
These are real fees you’ll pay out of pocket.
- Legal & Discharge Fees — A real estate lawyer needs to handle the transaction. Budget $800–$1,500.
- Appraisal Fee — Your new lender will want a professional appraisal of your home. Typically $300–$500.
So once you’ve filled everything in, hit Calculate Refinance and your results appear instantly.
Understanding Your Results
The Break Penalty
This is often the biggest shock for homeowners. And it’s important to understand how it’s calculated.
For variable-rate mortgages, the penalty is simple: three months’ interest on your remaining balance. Usually a few thousand dollars.
For fixed-rate mortgages, your lender charges whichever is greater:
- Three months’ interest, or
- The Interest Rate Differential (IRD)
The IRD is the difference between your locked-in rate and the rate your lender is currently offering for a similar term — multiplied by your balance and remaining months. If rates have dropped significantly since you locked in, your IRD penalty can reach tens of thousands of dollars. Big banks are known for particularly high IRD penalties because they use their posted rates (which are inflated) in the formula.
Your Monthly Savings
This is how much less you’d pay per month after refinancing. But — and this is critical — monthly savings alone don’t tell you if refinancing is worth it. You need to look at the break-even point too.
The Break-Even Point
Your break-even point is how many months of savings it takes to recover your total refinancing costs (penalty + legal fees + appraisal). If your break-even is 14 months and you have 36 months left on your term, refinancing makes great sense. If your break-even is 40 months but you only have 24 months left on your term, you’ll never recover the cost.
The 80% LTV Rule
In Canada, you can only refinance up to 80% of your home’s appraised value. So if your home is worth $700,000, the maximum mortgage after refinancing is $560,000. Go above that, and you’d need CMHC mortgage insurance — which adds a significant cost. Our calculator flags this automatically.
Should You Refinance or Just Wait for Renewal?
Look, this is the question most people get wrong.
If your mortgage term ends in the next 4–6 months, it almost always makes more financial sense to wait. At renewal, there’s no penalty. You simply negotiate new terms with your lender, or switch to a new one without paying a dime in break fees.
But if you’re in the middle of a 5-year term and rates have dropped by 1.5% or more, the math might favour breaking early — especially if you’re planning to stay in the home for several more years.
A good rule of thumb: if your break-even is under 24 months and you have more time than that left on your term, refinancing deserves a serious look.
And always get the actual penalty figure in writing from your lender before making any decision. The number can be very different from what this (or any) online calculator estimates, because each lender uses slightly different methods.
Refinancing to Consolidate Debt in Canada
This is one of the most practical reasons to refinance, and it’s often underused.
Say you’re carrying $40,000 in credit card debt at 20%. You’re paying around $666/month just in interest — and barely touching the principal. So you refinance your mortgage, roll that debt in at 4.5%, and your interest cost on that same $40,000 drops to about $150/month.
That’s over $500 saved per month, just on the interest.
Plus, there’s a real psychological win. Seeing all your debt wrapped into one monthly mortgage payment makes it easier to manage and track.
The catch? You’re turning short-term debt into a long-term mortgage. If you roll $40,000 of credit card debt into a 25-year mortgage, you could end up paying more in total interest — even at the lower rate — if you don’t make extra payments. Use the Consolidate Debt tab in our calculator to model the exact savings for your situation.
Accessing Home Equity Through Refinancing
Your home’s equity is the difference between what your home is worth and what you owe on your mortgage. And as home values across Canada have grown, many homeowners are sitting on significant equity they can actually use.
Refinancing to access equity works like this: you take out a new mortgage for more than your current balance, and the extra cash gets paid out to you. You can use it for home renovations, to help a child with a down payment, to cover medical costs — really anything.
But remember — you can only access up to 80% of your home’s value. And you’re now borrowing more, so your monthly payment will be higher than before (even at a lower rate, depending on how much equity you pull out).
Use the Access Equity tab in our calculator to see exactly how much you can access, what your new payment would be, and whether your new mortgage stays within the 80% LTV limit.
Fixed vs. Variable — Which Is Better for a Refinance?
If you’re breaking a fixed-rate mortgage, expect a larger penalty. The IRD formula can result in penalties of $10,000 to $30,000 or more if you locked in at a high rate and rates have since dropped.
But if you’re breaking a variable-rate mortgage, you’ll pay just three months’ interest — typically $3,000 to $6,000 on most Canadian mortgages. That’s much easier to recover from.
So if you’re considering whether to take a fixed or variable rate on your new mortgage after refinancing, think about your timeline. A shorter fixed term (2 or 3 years) gives you lower penalty risk if you need to break again. A variable rate gives you the most flexibility of all.
What Does Refinancing Cost in Canada?
Here’s a plain breakdown of typical fees:
Prepayment Penalty — The big one. Anywhere from $2,000 to $30,000+ depending on your lender, rate type, and how much time is left on your term.
Legal & Discharge Fees — Budget $800 to $1,500 for a real estate lawyer to handle the paperwork and discharge your old mortgage.
Appraisal Fee — Your new lender usually needs a professional appraisal. Typically $300 to $500. Some lenders cover this cost as an incentive to switch — always ask.
Mortgage Discharge Fee — If you’re switching to a new lender, your old one may charge $200 to $400 to formally discharge the mortgage.
And the good news? Some lenders offer to cover legal and appraisal costs if you bring your mortgage to them. It won’t always be on the table, but it’s absolutely worth negotiating.
Mortgage Refinance Rules in Canada (2026)
A few things you need to know before refinancing in Canada:
The 80% LTV Cap. You cannot refinance for more than 80% of your home’s appraised value without CMHC insurance. This applies to every lender across Canada.
The OSFI Stress Test. If you switch to a new lender, you must re-qualify under the federal stress test. That means proving you can afford payments at the higher of 5.25% or your new contract rate plus 2%. So if your new rate is 4.5%, you’d need to qualify at 6.5%.
But — if you’re staying with your existing lender and just renegotiating your rate, you might avoid the stress test entirely. This is worth asking your lender about directly.
Semi-Annual Compounding. Under Canada’s Interest Act, mortgages must be compounded semi-annually (not monthly like in the U.S.). Our calculator uses the correct formula for this, so your numbers reflect actual Canadian mortgage math — not American calculations.
FAQ
How much can I refinance my mortgage for in Canada?
You can refinance up to 80% of your home’s current appraised value, minus your outstanding mortgage balance. For example, if your home is worth $800,000 and you owe $500,000, you could access up to $140,000 in equity ($640,000 maximum mortgage − $500,000 balance = $140,000 available).
Can I refinance my mortgage before the term ends?
Yes. You can break your mortgage at any time. But you’ll pay a prepayment penalty to do it. Whether that penalty is worth paying depends on your monthly savings and your break-even timeline — which is exactly what this calculator shows you.
What is an IRD penalty in Canada?
IRD stands for Interest Rate Differential. It’s the penalty fixed-rate mortgage holders pay when breaking their mortgage early. It’s calculated as the difference between your current rate and the rate your lender is currently offering for a similar remaining term — multiplied by your balance and the time left. Big banks often charge far more than smaller lenders and credit unions for IRD penalties.
Is refinancing the same as renewing my mortgage?
No. Renewal is when your current term naturally expires and you sign new terms — no penalty, minimal paperwork. Refinancing means breaking your existing term early, usually to get a better rate, access equity, or consolidate debt. Refinancing costs more upfront but can make sense if the savings are large enough.
How long does it take to refinance a mortgage in Canada?
The process typically takes 2 to 4 weeks from application to funding. You’ll need to provide proof of income, a property appraisal, and details about your current mortgage. In Quebec, it can take longer because mortgage transactions require a notary instead of a standard real estate lawyer.
Can I refinance if I’m self-employed?
Yes, but it’s harder. Self-employed borrowers need to provide more documentation — typically 2 years of Notice of Assessment (NOA) from the CRA, business financials, and sometimes a letter from an accountant. Some borrowers in this situation end up with alternative (B) lenders at higher rates. A mortgage broker who works with multiple lenders is your best bet here.
What’s the difference between refinancing and a HELOC?
A Home Equity Line of Credit (HELOC) lets you borrow against your equity without breaking your mortgage. You only pay interest on what you use. Refinancing gives you a lump sum but costs more upfront (penalties and fees). A HELOC is better for ongoing or unpredictable expenses. Refinancing is better for a large one-time need or to lower your rate.
