Using a HELOC to Pay Off Debt in Canada 2025
The core trade-off: Using a HELOC to consolidate high-interest debt can save thousands in interest — but you're converting unsecured debt into debt secured by your home. If you can't repay, you risk your home. Discipline is essential.
Paying off high-interest credit card debt or a car loan with your HELOC seems like a no-brainer when you compare 19.99% credit card rates to a HELOC at 5.45%. The math works — but the strategy comes with real behavioural and financial risks that you need to understand before proceeding.
The Interest Savings Case
The interest rate difference between consumer debt and a HELOC is enormous:
| Debt Type | Typical Rate | Interest on $30,000/yr |
|---|
| Credit card | 19.99% | $5,997 |
| Personal loan | 9.99% | $2,997 |
| Auto loan | 7.99% | $2,397 |
| HELOC | 5.45% | $1,635 |
Moving $30,000 in credit card debt to a HELOC saves roughly $4,362 per year in interest. Over 3 years of paying it off, that's over $13,000 in savings.
How Debt Consolidation with a HELOC Works
- Determine how much HELOC room you have available (see our home equity calculator)
- Apply for a HELOC or draw from your existing one
- Use the HELOC funds to pay off credit cards, personal loans, or other high-interest debts
- Close or reduce limits on the paid-off credit cards (prevents re-accumulation)
- Set a structured repayment plan for the HELOC — treat it like a term loan, not a revolving balance
The Critical Risk: Trading Unsecured for Secured Debt
Credit card debt is unsecured. If you can't pay it, your credit suffers and you may face collections — but you don't lose your home. HELOC debt is secured by your property. Defaulting on a HELOC can result in the lender beginning power of sale or foreclosure proceedings.
This risk is manageable for people with stable incomes and disciplined spending habits — but it's a real consequence that must be weighed honestly.
The debt spiral trap: The most common failure mode is consolidating credit card debt to a HELOC, then running up the credit cards again. You now have both HELOC debt AND new credit card debt. This is why closing or significantly reducing the paid-off cards immediately is critical.
Building a HELOC Debt Payoff Plan
Don't treat the HELOC like a credit card with an unlimited minimum payment option. Set a concrete payoff timeline:
- Decide your payoff horizon: 2, 3, or 5 years
- Calculate the required monthly payment (principal + interest)
- Set up automatic payments for that amount
- Apply any windfalls (tax refunds, bonuses) directly to the HELOC balance
Payment Comparison: Minimum vs Structured HELOC Payoff
| Approach | Monthly Payment | Paid Off In | Total Interest |
|---|
| Interest only ($30K at 5.45%) | $136 | Never | Infinite |
| 3-year payoff | $908 | 36 months | $2,697 |
| 5-year payoff | $573 | 60 months | $4,380 |
Best practice: When you consolidate debt to a HELOC, immediately set up a recurring automatic payment that mirrors what you were paying on the original debt. If you were paying $900/month on credit cards, keep paying $900/month on your HELOC — you'll pay it off rapidly while maintaining your cash flow habits.
Who Benefits Most from HELOC Debt Consolidation
- Homeowners with 20%+ equity and sufficient HELOC room
- People with high-interest credit card or personal loan balances ($15,000+)
- Those with stable income who can commit to structured repayment
- Borrowers who are willing to close or freeze their credit cards after consolidating
When to Avoid HELOC Debt Consolidation
- If the root cause of the debt (overspending) hasn't been addressed
- If your income is unstable or you're at risk of job loss
- If the HELOC would consume most of your available home equity, leaving no buffer
- If you have a history of running up consolidated debts again

Frequently Asked Questions
Should I close my credit cards after using a HELOC to pay them off?
At minimum, reduce the credit limits significantly or put the cards away. Closing cards entirely can temporarily hurt your credit score by reducing available credit. The most important thing is preventing re-accumulation of balances.
Does consolidating debt with a HELOC hurt my credit?
Not directly — paying off revolving debt typically improves your credit utilization ratio, which helps your score. The HELOC application itself involves a hard inquiry.
What if I can't repay the HELOC?
Contact your lender immediately to discuss options — interest-only periods, payment deferral, or renegotiating terms. Don't wait until you've missed payments. Lenders prefer to work with borrowers proactively.
