Roll high-rate debts into your mortgage.

Fact-checked by Surrayya Afzal, Principal Broker, FSRA #M14001433·Last reviewed October 2026
The short answer

Moving high-interest debt into your mortgage can lower your monthly payment; lifetime interest may increase. The debt is then secured by your home and spread over a longer time.

Lower payment, longer runway — model the lifetime cost

Consolidating works because mortgage money is cheap relative to credit cards and unsecured lines. Swapping 19.99% revolving debt for a sub-5% mortgage rate can slash the interest you pay each year and free up real monthly cashflow — the before/after bars above show exactly how much.

The trade-off no one mentions

The catch is amortization. A balance you might have cleared in two or three years now rides on a 25-year mortgage. Even at a far lower rate, stretching it that long can mean more total interest on that slice over its life. That’s why the donut above models lifetime cost, not just the monthly drop — the smart play is often to consolidate for the cashflow relief, then apply prepayment privileges to clear the consolidated portion fast.

Two guardrails we put on every file: keep the new financing under 80% of your home’s value, and close or reduce the unsecured limits you just paid off so the debt doesn’t rebuild. If you don’t have the equity to refinance, a HELOC or a full refinance comparison is the next step.

How to use this calculator
  1. Enter your debtsAdd each balance, interest rate, and monthly payment — credit cards, lines of credit, auto loans, whatever carries a rate above your mortgage. Takes about 60 seconds.
  2. Set your consolidation rateEnter the refinance rate you've been quoted (or use the live default). The calculator prices the rolled-in debt at that rate over your chosen amortization so you see the exact trade-off.
  3. Review the full picture — then call usCompare your combined payment today versus one consolidated mortgage payment, plus lifetime interest costs. Once the math makes sense, we shop 100+ lenders to find the actual rate.
How this is calculated
Consolidating extends your debt over 25 years, so the lifetime interest may be higher even when monthly payments drop. We model the all-in cost before recommending.
FAQ

Common questions

Don’t see yours? Ask Maya.

How much can debt consolidation actually save me?
Significant. Example: $30K of credit card debt at 21% costs $6,300/yr in interest. Rolling it into a mortgage at an assumed 4.59% (illustrative, not a quote) costs $1,377/yr — annual savings of $4,900. Plus the principal is now amortizing instead of revolving. Whether you save over the full life depends on how quickly you repay the consolidated amount. Confirm the rate against a true refinance.
What's the catch with debt consolidation refinancing?
Behaviour. Consolidation frees up the cards and lines you just paid off, and if they fill up again you end up with the bigger mortgage and new unsecured debt, with your home securing more of it (FCAC). That is why we recommend closing or lowering the unsecured limits as part of every consolidation file.
Will my mortgage payment go up after consolidation?
Usually yes — the mortgage balance is larger, so the payment is higher. BUT the TOTAL of mortgage + cards + lines + car payments is typically much lower than before. The bars compare the debt portion only. Your full new mortgage payment depends on the existing mortgage balance and refinance rate.
Doesn't stretching debt over 25 years cost more in the long run?
It can. A $5,000 credit-card balance you'd clear in 18 months becomes a 25-year obligation inside your mortgage, so even at a far lower rate the lifetime interest on that slice may exceed paying it off fast. That's why we model lifetime cost — shown in the donut above — not just the monthly drop, and often recommend keeping a faster payoff on the consolidated portion.
Can I consolidate CRA tax debt into a mortgage?
Yes — most A-lenders refinance with CRA debt cleared at closing (no lien yet). Some B-lenders will refinance with CRA arrears paid from the proceeds, typically at lower maximum LTVs than A-lenders; policies vary by lender. See our CRA debt page for the full playbook.
How much equity do I need to consolidate into my mortgage?
With a prime (A-lender) refinance you can borrow up to 80% of your home's value (OSFI). Your existing mortgage balance plus the debts you roll in must stay under that 80% ceiling, and a HELOC has to fit under the same combined limit. Alternative and private lender limits and fees vary; borrowing above 80% is not assured.
What's the difference between consolidating via refi vs HELOC?
For a fixed balance you plan to repay over years, a refinance may cost less once break penalties and fees are counted. A HELOC allows flexible draws and repayment. We model both on every file.
How much can debt consolidation save me each month?
It depends on your balances and rates, but the saving can be significant. A $30,000 credit card balance at 21% costs $6,300 per year in interest alone. Rolling it into a mortgage at today's rates costs a fraction of that. Use the calculator above to see the exact monthly saving on your own numbers — it adjusts in real time.
Does consolidating my debt into a mortgage increase my mortgage payment?
Your mortgage payment goes up because the balance is larger, but your total monthly outflow — mortgage plus all the separate card and loan payments — is typically much lower. The calculator shows both figures side by side so you can see the net impact before making any decision.
What is the maximum I can consolidate through a mortgage refinance?
On a prime A-lender refinance, your new mortgage cannot exceed 80% of your home's appraised value. Subtract what you currently owe from that limit — the remainder is the maximum you can roll in. Going above 80% requires a B-lender or private second mortgage at higher rates. We model the LTV on every file.
Do I need equity in my home to consolidate debt?
Yes — you're borrowing against your home's value. The standard threshold is 20% equity remaining after the refinance (i.e., you can borrow up to 80% LTV). If you don't yet have enough equity, a HELOC or a second mortgage may cover part of the debt. We compare all paths side by side on every file.
Is there a fee to consolidate through Mortgage Squad?
$0 on standard A-lender refinances. The lender pays our finder fee at closing, disclosed in writing on every file. B-lender and private files may carry a brokerage fee — always quoted upfront and never deducted without your written consent.
