It depends on your numbers and your habits. Refinancing your home to pay off credit card debt can make sense when high-interest balances are creating cash-flow stress and you have sufficient equity. It's not always the right move for everyone.
Here's the honest breakdown of when this strategy works, when it doesn't, and what to actually look at before you sign anything.
Why Refinancing for Credit Card Debt Can Make Sense
Credit card interest rates in Canada are typically 19% to 29%. Mortgage rates are significantly lower. Rolling high-interest debt into your mortgage may reduce your monthly payments and total interest paid over time, especially if you commit to actually paying it down rather than treating the freed-up cash as new spending room.
The math works most clearly when:
- You're carrying $20,000 or more in credit card or high-interest debt
- You have at least 20% equity in your home
- Your current mortgage rate plus the refinance penalty is still competitive with today's rates
- Your spending patterns have stabilized (this matters more than the math)
The math problem is easy to solve. The behaviour problem is what trips most homeowners up.
The Real Cost of Refinancing for Debt Consolidation
Refinancing isn't free. Before you compare the interest savings, you need to know the actual costs:
- Legal fees: typically $900 to $1,500
- Appraisal: $400 to $700
- Title insurance: $150 to $400
- Discharge fees from your old lender: $250 to $400
- Mortgage penalty (if breaking mid-term): can be significant on a fixed-rate mortgage. The Interest Rate Differential calculation surprises a lot of homeowners.
Add it up. If your interest savings over the next 12 months don't exceed your total refinance costs, the math doesn't make sense. A good broker runs this calculation honestly before recommending anything, and you can run it yourself first using my refinance savings calculator.
Before refinancing, ask your current lender for the exact penalty in writing. Banks often quote a verbal estimate that's lower than the actual figure. The written calculation is the only number that matters.
The Trade-Off Most People Miss
Refinancing converts short-term debt into long-term debt. Your $30,000 in credit card balances might disappear from your statements, but it just got rolled into a 25-year amortization on your mortgage. Even at a lower rate, paying that $30,000 over 25 years means you'll pay interest on it for two decades.
The fix: don't extend your amortization. Keep the same end date as your existing mortgage. Your monthly payment will be higher than the minimum, but you actually pay off the debt instead of stretching it forever.

Book a Discovery CallWhen Refinancing for Debt Consolidation Doesn't Make Sense
Walk away if any of these apply:
- You're planning to sell your home within 2 years (the costs won't be recovered)
- The spending pattern that created the debt hasn't changed
- Your mortgage penalty is more than your annual interest savings
- You're already deep into your amortization and refinancing resets you to a fresh 25 or 30 years
- You have a viable plan to pay the cards off in 12 to 24 months without touching your mortgage
Common Questions
Is refinancing to pay off credit cards a good idea in Ontario?
It can be. Credit card rates of 19% to 29% are significantly higher than mortgage rates, so rolling that debt into your mortgage may reduce your monthly payments and total interest. The trade-off is that you turn short-term debt into long-term debt, so the strategy only works if you commit to paying it down rather than stretching it across a fresh 25-year amortization.
Will refinancing lower my monthly payments?
In most cases, yes. Spreading the balance over a longer amortization at a lower rate typically drops the monthly payment. The risk is paying interest for far longer if you don't actively pay it down faster than the minimum.
How much home equity do I need to refinance for debt consolidation?
In Ontario, lenders typically allow refinancing up to 80% of your home's value. The equity you have available after your current mortgage balance determines how much debt you can roll in.
Does refinancing to pay off credit cards hurt my credit score?
Long term, it can help. Paying off high-utilization credit cards often improves your credit profile within a few months. The refinance itself involves a credit check and a new loan registered against your home, which may cause a short-term dip, but the dip is usually small and recoverable.
Is it better to refinance or use a HELOC to pay off credit cards?
A refinance offers stability: a fixed payment and rate for a set term. A HELOC offers flexibility but comes with a variable rate and the temptation of balances creeping back up. The right choice depends on your discipline, your cash flow, and what you plan to do in the next 5 years.
What's the biggest risk of refinancing to pay off credit card debt?
Re-accumulating the debt. If the spending pattern that created the original debt isn't addressed, homeowners can end up with both a higher mortgage and new credit card balances. The math doesn't fix the behaviour.
