Key Highlights
- Debt consolidation combines multiple debts into a single loan with one repayment meaning it can reduce your monthly outgoings significantly but it does not reduce the total amount you owe
- Homeowners have access to the most powerful consolidation option: rolling high-interest debts into a home loan at a much lower interest rate, potentially saving thousands per year in interest
- The biggest risk of mortgage-based consolidation is paying off short-term consumer debt over 25 to 30 years as the lower monthly payment can hide a much higher total interest cost over the full loan term
- A broker can structure the consolidation correctly such as splitting the rolled-in debt into a separate loan with a shorter term prevents the total interest trap while still capturing the lower rate
- Debt consolidation only works long-term if you address the spending behaviour that created the debt including consolidating and then rebuilding credit card balances leaves you in a worse position than before
Multiple Debts, Multiple Repayments, Multiple Interest Rates
A credit card at 20%. A car loan at 11%. A personal loan at 14%. A BNPL account you hardly use but cannot seem to pay off. For many Australians, managing debt means managing a different lender, a different due date, a different interest rate, and a different direct debit every month. The administrative burden alone is exhausting, and the combined interest cost is usually far higher than it needs to be.
Debt consolidation is the process of combining some or all of those debts into a single loan with one repayment, one interest rate, and one lender. Done correctly, it simplifies your financial life and reduces the total interest you pay. Done incorrectly, it can make things significantly worse.
For homeowners, debt consolidation can be even more powerful than a standard personal consolidation loan. Rolling high-interest consumer debt into a home loan reduces the interest rate on that debt dramatically. The risk is in the term and understanding how to manage that risk is the difference between consolidation that works and consolidation that costs you more in the long run.
This guide covers all three debt consolidation approaches available in Australia, the maths behind them, and the common mistakes to avoid. If you own a home and are carrying consumer debt, read the mortgage-based consolidation section carefully as it is the option most people do not know is available and the one most likely to produce a genuine financial improvement.
What Is Debt Consolidation?
Debt consolidation is taking two or more existing debts and combining them into a single new loan. The new loan pays off all the existing debts, and you are left with one balance, one interest rate, and one monthly repayment.
The consolidation does not reduce the amount you owe. If you have $43,000 in debts, consolidation means you have one $43,000 loan instead of several smaller ones. What it can change is the interest rate applied to that balance and the monthly repayment amount.
The financial benefit comes from the rate differential. Consumer debts such as credit cards, personal loans, car loans, BNPL carry interest rates ranging from 8% to 25% per annum. A consolidation loan at a lower rate reduces the interest cost on the same balance, freeing up cash flow each month and reducing the total interest paid over the repayment period.
Types of Debt Commonly Consolidated
Most consumer debts can be consolidated. The most common are:
- Credit cards: the highest-interest debt most Australians carry, typically 15% to 22% per annum on outstanding balances. Credit card debt is revolving, balances grow if minimum payments are made and spending continues, making it one of the most dangerous forms of debt to carry long-term
- Personal loans: fixed term loans used for holidays, home improvements, medical costs, or any personal purpose. Rates typically range from 7% to 20% per annum depending on the lender and the borrower’s credit profile
- Car loans: secured asset finance typically at 6% to 15% per annum. A car loan mid-term can often be consolidated into a home loan or personal loan at a lower rate, though the secured nature of the original loan means the car is no longer collateral once it is paid out
- Buy now pay later (BNPL): BNPL accounts like Afterpay, Zip Pay, and similar services do not charge interest but do charge late fees and have minimum fortnightly repayments that affect serviceability. Lenders count each active BNPL account as a credit commitment in the home loan assessment. Closing BNPL accounts before applying for any form of consolidation or home finance can improve your assessed borrowing capacity
- Store credit: retail credit accounts and store cards carry rates comparable to or above standard credit cards and are often the last debts people think to include in a consolidation

The Three Debt Consolidation Options
| Option | Typical Rate | Best For | Key Risk |
| Personal debt consolidation loan | 8% to 20% p.a. | Renters or low equity owners | Higher rate than mortgage |
| Debt rolled into home loan | 5.6% to 5.9% p.a. | Homeowners with sufficient equity | Paying short-term debt over 30 years |
| Refinance to consolidate | 5.6% to 5.9% p.a. | Those also seeking a better rate | Break costs if currently fixed |
Option 1: Personal debt consolidation loan
A personal debt consolidation loan is an unsecured or secured personal loan used specifically to pay out existing debts. You borrow a single amount, use it to clear the outstanding balances on your other debts, and repay the new consolidated loan over an agreed term, typically one to seven years.
Personal consolidation loans are available to both renters and homeowners and do not require property equity to access. The rate you receive depends on your credit score, income, and the lender’s assessment of your risk profile. A borrower with strong credit and stable income can access rates from approximately 7% to 10% per annum on a secured personal loan. Those with impaired credit or recent defaults may see rates from 12% to 20%.
The advantages of a personal loan consolidation are simplicity, speed (most are approved within 24 to 48 hours), and the fact that the consolidation debt sits outside your home loan and is repaid over a defined short term. The disadvantage is that the rate is almost always higher than a home loan rate, so the interest saving versus consumer debts exists but is more modest than mortgage-based consolidation.
- Best for: renters, homeowners without sufficient equity, those consolidating smaller debt amounts, or those who want the debt separated from their home loan
- Rate range: approximately 7% to 20% p.a. depending on credit profile and lender
- Term: one to seven years
Option 2: Rolling debts into your home loan
For homeowners with available equity, the most financially powerful consolidation option is drawing on that equity to pay out consumer debts and rolling them into the home loan balance. The result is a single loan at the home loan interest rate — currently approximately 5.6% to 5.9% for standard variable products — replacing consumer debts carrying rates of 10% to 22%.
The mechanics are straightforward: you apply to your lender to increase your home loan balance by the amount of consumer debt you want to clear. The lender assesses whether your equity and income support the increase. If approved, the additional funds are released and you use them to pay out the other debts. Your total home loan balance is higher but your monthly obligation across all debts combined is typically much lower.
- Best for: homeowners with at least 20% equity after the consolidation amount is added, those with significant consumer debt at high rates, and those who will actively work to pay down the consolidated amount
- Rate: your home loan rate, typically 5.6% to 5.9% on standard variable products as at April 2026
- Key risk: adding consumer debt to a 25 to 30 year home loan. See the section on the term risk below
Option 3: Refinancing to consolidate
A refinance-to-consolidate approach moves your home loan to a new lender at the same time as drawing equity to clear consumer debts. The benefit is the ability to simultaneously access a better interest rate on the home loan and consolidate consumer debt in a single transaction.
This option is most relevant when your existing home loan rate is above market, your fixed rate period has expired and you are sitting on the standard variable rate, or you have not reviewed your home loan in two or more years and suspect you are paying more than you need to. A broker can calculate whether the refinancing cost — discharge fee from the existing lender, new loan establishment fee — is more than offset by the rate improvement and debt consolidation saving.
- Best for: those with an uncompetitive home loan rate who also want to consolidate consumer debt
- Key risk: break costs if currently on a fixed rate, and the same loan term risk as Option 2
- Note: if you recently fixed your home loan, check with your broker whether break costs apply before refinancing
A broker can model all three options at your actual loan balance and debt amounts before you make any decision. The right option depends on your equity position, your current home loan rate, your credit score, and how much consumer debt you are carrying. There is no universal answer.

Three ways to consolidate debt in Australia
Typical interest rate comparison
The Maths of Debt Consolidation: A Worked Example
The following example shows a homeowner carrying $43,000 in consumer debt across four accounts and the financial effect of rolling those debts into their home loan.
Before consolidation
| Debt | Balance | Current Rate | Monthly Payment |
| Credit card 1 | $8,000 | 21% p.a. | $240 |
| Credit card 2 | $5,000 | 19% p.a. | $150 |
| Car loan | $18,000 | 11% p.a. | $420 |
| Personal loan | $12,000 | 14% p.a. | $280 |
| Total | $43,000 | Blended ~16% | $1,090 |
After rolling into home loan
| Consolidated into home loan top-up | $43,000 | 5.8% p.a. | $253 |
| Monthly saving | — | — | $837 |
| Annual saving | — | — | $10,044 |
The monthly saving of $837 and annual saving of $10,044 looks compelling and it is real in the short term. The critical number this table does not show is the total interest paid if the $43,000 sits in the home loan for the remaining 25 years of the mortgage. At 5.8%, that $43,000 accrues approximately $38,000 in interest over 25 years. Compared to paying off a personal loan in three years at 14%, the total interest position over the full home loan term can be worse despite the lower monthly payment.
This is the central risk of mortgage-based debt consolidation. A lower monthly payment is not the same as a lower total cost. The solution is not to avoid the consolidation — it is to treat the consolidated amount as a separate debt with a shorter repayment target. A broker can structure a separate loan split for the consolidated amount with a 5 to 7 year repayment term rather than letting it sit in the main home loan for 25 years.

Important: The lower monthly payment is real — but if the $43,000 sits in a 25-year home loan at 5.8%, the total interest paid is approximately $38,000 over the full term. Set up the consolidated amount as a separate split with a 5 to 7 year repayment target to capture the rate saving without the term trap.

When Debt Consolidation Makes Sense and When It Does Not
When consolidation makes sense
- You are making minimum payments on multiple high-interest debts and making no meaningful progress on the balances
- The combined monthly repayments on your debts are creating genuine cash flow stress
- You have sufficient equity in your home to consolidate without pushing your LVR above 80%
- You are committed to closing the credit accounts you are consolidating and not rebuilding balances
- You plan to aggressively repay the consolidated amount over a defined shorter period rather than letting it ride in the home loan
- You are planning to refinance your home loan anyway, making the transaction cost of consolidating at the same time minimal
When consolidation does not make sense
- Your existing debts are small and close to being paid off, consolidating into a longer-term loan adds interest cost rather than reducing it
- You do not have sufficient equity in your home or your income cannot support the increased home loan balance
- You have not addressed the spending behaviour that created the debt, consolidating and then rebuilding credit card balances is one of the most common and most expensive financial mistakes in Australia
- Your home loan is in a fixed rate period with significant break costs that exceed the consolidation saving
- You are close to retirement and adding debt to your home loan extends the term into retirement income
The Loan Term Risk: The Most Misunderstood Part of Mortgage Consolidation
It is worth spending more time on the loan term risk because it is genuinely counter-intuitive and it is the mechanism through which mortgage-based consolidation most commonly produces worse outcomes than expected.
Consumer debts such as credit cards, personal loans, car loans, etc are short-term debts. Most are structured to be repaid in one to seven years. The interest cost over that short term, even at a high rate, is bounded by the repayment period.
A home loan is a long-term debt. When you roll $43,000 of short-term consumer debt into a 25-year home loan, you are extending the repayment horizon of that $43,000 from the original 1 to 7 years out to 25 years. Even at a much lower rate, 25 years of interest on $43,000 can significantly exceed 3 years of interest on the same amount at a higher rate.
The solution is elegant but requires deliberate structuring:
- Ask your broker to set up the consolidated amount as a separate loan split with a fixed end date of 5 to 7 years, not as an addition to the main 25-year loan balance
- Make sure the monthly repayment on the consolidation split pays it off within the target term rather than making interest-only repayments
- Treat the consolidation split as a debt elimination target, every dollar extra applied to it shortens the term and reduces the total interest payable
This structuring approach, a separate, shorter-term split for the consolidated amount is exactly the kind of advice a broker provides that a bank branch rarely mentions. The bank’s default approach is to add the debt to the main loan term, which produces the highest long-term interest revenue for the bank. A broker’s incentive is to get the structure right for the borrower.
How Debt Consolidation Affects Your Credit Score
Debt consolidation generally has a neutral to positive effect on your credit score over the medium term, but there are short-term impacts to understand.
Short-term credit score effects
- New credit application: applying for any consolidation loan generates a credit enquiry on your file, which can reduce your credit score slightly in the short term. Multiple applications within a short period are more damaging than a single well-researched application — a broker can assess which lender is most likely to approve you before lodging any application that creates an enquiry
- Closing accounts: closing credit card and personal loan accounts after paying them out through consolidation reduces your total available credit. This can temporarily lower your score even though your financial position has improved. Over time, reduced utilisation and consistent repayment of the consolidation loan improves the score more than account closure hurts it
Medium-term credit score effects
- Reduced utilisation: if you close the credit cards being consolidated and do not open new ones, your credit utilisation ratio — the proportion of your available credit you are using — falls. Lower utilisation is one of the strongest positive signals in a credit score calculation
- Consistent repayment: making regular on-time repayments on the consolidation loan builds positive payment history, which is the most heavily weighted factor in most credit scoring models
- Simplified obligations: managing one repayment reduces the risk of missed payments due to administrative complexity. A missed payment due to juggling multiple accounts is just as damaging to your score as a missed payment due to inability to pay
Common Mistakes With Debt Consolidation
Mistake 1: consolidating and then rebuilding the debt
This is the single most common and most damaging debt consolidation mistake. You consolidate $25,000 in credit card debt into your home loan, feel financial relief, and within 18 months the credit card balances are back to $20,000 while you are also carrying the extra $25,000 in your mortgage. You are now in a significantly worse position than before the consolidation.
The solution is to close (not just pay out) the credit card accounts being consolidated. If you need a credit card for legitimate purposes, keep one card with a limit appropriate for your actual usage and close the rest. Most people carry more credit card limit than they need, and having less available credit reduces the temptation and the risk.
Mistake 2: focusing only on the monthly payment
A lower monthly payment feels like financial progress. It is only genuine progress if it is also accompanied by a lower total interest cost over the full repayment period. Always ask: how much total interest will I pay on this consolidated loan over the full term? Compare that to the total interest you would pay on the existing debts if you continued repaying them at the current rate. The answer may surprise you.
Mistake 3: consolidating without addressing the cause
Debt consolidation is a financial restructuring tool, not a spending behaviour cure. If the consumer debts being consolidated were accumulated due to spending more than you earn, consolidation provides temporary relief but does not change the underlying dynamic. A conversation with a financial counsellor or the National Debt Helpline (1800 007 007) alongside the consolidation can address the behavioural component that consolidation alone cannot fix.
Mistake 4: not considering BNPL accounts
Many borrowers consolidate their formal debts but overlook active BNPL accounts. Every active BNPL account is counted as a credit commitment by lenders in a home loan or consolidation loan serviceability assessment, regardless of the balance. Closing inactive BNPL accounts before any loan application can materially improve your assessed borrowing capacity and reduce the interest you pay across your full debt portfolio.
Mistake 5: applying to multiple lenders without guidance
Each home loan or personal loan application generates a credit enquiry on your file. If you are shopping around by submitting multiple applications to different lenders, each one reduces your credit score slightly and lenders can see the other recent enquiries, which signals financial stress and reduces approval prospects. A broker makes a single enquiry on your behalf and pre-assesses your eligibility before any application is lodged.
How a Broker Helps With Debt Consolidation
Most people approaching debt consolidation go directly to their bank. There is nothing wrong with this, but it has limitations: you see only what that bank offers, the bank structures the consolidation in a way that suits their product suite, and no one explains the loan term trap or the account closure strategy.
A broker with access to a full lender panel brings a different perspective:
- We assess all three consolidation options — personal loan, home loan top-up, and refinance to consolidate — and identify which produces the best total cost outcome for your specific debts, equity position, and income
- We structure the consolidated debt correctly from the start — as a separate split with a shorter term rather than buried in the main home loan balance
- We protect your credit file by assessing likely approval before lodging any application that creates an enquiry
- We identify whether BNPL and store cards are affecting your assessed borrowing capacity and advise on which to close before application
- We compare refinancing costs against consolidation savings to confirm whether a full refinance-to-consolidate makes sense at your current loan balance and rate
- Our service costs you nothing as we are paid by the lender at settlement
Debt consolidation that reduces your monthly outgoings, eliminates high-interest consumer debts, and is structured with a clear shorter-term repayment target for the consolidated amount is one of the most effective financial improvements a homeowner can make.

Frequently Asked Questions
Is it a good idea to consolidate debt into your mortgage?
It can be, if you have sufficient equity, the rate differential is significant, and you structure the consolidated amount as a separate shorter-term split rather than letting it sit in a 25-year home loan. The risk is the loan term trap: a lower monthly payment can hide a higher total interest cost over the full home loan term. A broker can model the total cost of consolidation versus continuing to repay consumer debts separately and recommend the right structure.
What debts can be consolidated?
Most consumer debts can be consolidated including credit cards, personal loans, car loans, store credit, and BNPL accounts. Tax debts and student loans (HECS-HELP) cannot be consolidated through standard consumer finance products. The most financially significant debts to consolidate are those carrying the highest interest rates — credit cards at 15% to 22% per annum produce the largest interest saving when rolled into a home loan or personal consolidation loan.
Does debt consolidation hurt your credit score?
Short-term: a new loan application creates a credit enquiry that can reduce your score slightly. Closing multiple accounts after consolidating may temporarily reduce available credit. Medium-term: the combination of reduced credit utilisation, simplified repayment obligations, and consistent on-time payments on the consolidation loan typically improves your credit score over 12 to 24 months.
Can I consolidate debt if I have bad credit?
It is more challenging but not impossible. Personal consolidation loans are available to borrowers with impaired credit through specialist lenders, typically at higher rates. Mortgage-based consolidation requires sufficient home equity and lender approval of the increased loan amount. A broker can identify which lenders are most likely to approve a consolidation application at your specific credit profile before any application is lodged.
How much can I save by consolidating debt?
The saving depends on the total amount of debt, the current interest rates on each account, and the rate on the consolidation loan. As a general guide, a homeowner consolidating $43,000 in consumer debt at an average rate of 16% per annum into a home loan at 5.8% could reduce their monthly debt repayments by over $800 per month. Total interest savings over the consolidation repayment period depend on the term used — a broker can model the exact figures for your situation.
What is the difference between debt consolidation and refinancing?
Refinancing means moving your home loan to a new lender, typically to access a better interest rate. Debt consolidation means combining multiple debts into one. A refinance-to-consolidate transaction does both simultaneously, you move lenders to access a better rate and draw equity at the same time to clear consumer debts. If you are already on a competitive rate and just want to consolidate consumer debt, a home loan top-up with your existing lender may be faster and cheaper than a full refinance.

5 common debt consolidation mistakes — and how to avoid them
Consolidating and then rebuilding the debt
The most common and costly mistake. You consolidate $25,000 in credit card debt, feel financial relief — and within 18 months the balances are back. Now you have the credit card debt and the consolidated amount in your home loan.
Fix: close the accounts being consolidated — don't just pay them out
Focusing only on the monthly payment
A lower monthly payment feels like progress but isn't if the total interest over the full term is higher. Always calculate total interest paid, not just the repayment.
Ask: what is the total interest over the full term?
Not addressing the spending behaviour
Consolidation restructures debt — it doesn't cure overspending. Without addressing the underlying behaviour, the debt comes back.
National Debt Helpline: 1800 007 007 (free financial counselling)
Forgetting BNPL accounts
Every active Afterpay, Zip, or Klarna account counts as a credit commitment in a home loan assessment — regardless of the balance. Close inactive accounts before applying.
Each active BNPL account reduces borrowing capacity
Applying to multiple lenders
Each application creates a credit enquiry that reduces your score. Multiple enquiries in a short period signal financial stress to lenders and can trigger declines.
A broker assesses eligibility before lodging any enquiry
The right sequence: close accounts being consolidated → set up consolidated debt as a separate shorter-term split → address spending habits → don't open new credit immediately after consolidating.
