Does consolidating debt hurt my credit score in Australia?

Applying for a personal loan creates a hard enquiry on your credit file, which typically causes a small, temporary dip — around 5 to 10 points. However, successfully managing a single consolidated loan and closing multiple accounts can improve your credit score over the medium term by simplifying your credit profile and reducing utilisation. The short-term impact is minor for most borrowers; the long-term effect of clearing debt is generally positive.

Can I include BNPL in a debt consolidation loan?

Yes. BNPL balances — Afterpay, Zip, Humm, and similar — can be included in a personal loan consolidation. They're typically interest-free, but they carry scheduled repayment obligations that affect your cash flow and debt-to-income ratio. Including them in a consolidation removes those obligations and simplifies your repayment structure. Note that some BNPL providers charge late fees that aren't reflected in a 0% rate — clearing them via consolidation removes that risk entirely.

What if I have bad credit — can I still consolidate?

Yes, though the rate you're offered will be higher, which makes the consolidation maths harder to justify. Lenders specialising in bad credit personal loans do operate in Australia, but compare the comparison rate carefully. If the consolidation rate is higher than your existing debt rates, consolidation will cost you more — the calculator will flag this directly. A rate check from LoanGorilla gives you a real number to work with before committing.

Is it worth consolidating small amounts of debt?

For totals under $2,000, establishment fees often offset the interest savings. A $300 fee on a $1,500 consolidation is 20% of the loan upfront — you'd need significant interest savings over several years to recover that cost. Below $2,000, a direct payoff strategy targeting the highest-rate debt first is almost always better. The calculator shows a note when your total balance falls below this threshold.

What fees should I expect on a consolidation loan in Australia?

Common fees include: establishment or application fee ($0–$600 depending on the lender), monthly account-keeping fee ($0–$15), and early repayment fee on some fixed-rate products. Some online lenders advertise zero-fee personal loans — always check the comparison rate, which includes most fees and gives a truer cost per annum than the advertised interest rate alone. The fee field in this calculator lets you model upfront costs accurately.

Can I consolidate a car loan?

Yes. Car loans can be included in a debt consolidation personal loan. If the car loan is secured — meaning the car is collateral — you may need to discharge that security as part of the refinance. Personal consolidation loans are typically unsecured, so the rate on the consolidated loan may differ from your existing secured car loan rate. Enter the expected consolidation rate into the calculator to check whether it still works in your favour after accounting for this.

Will I actually save money by consolidating?

It depends on three variables: the consolidation rate (lower than your average existing rate is good), the loan term (similar to or shorter than your current weighted payoff period is good), and the fees (low relative to total balance is good). When all three work in your favour, consolidation saves money on both a monthly and total-cost basis. When any one of them is unfavourable, the outcome shifts. The calculator models all three simultaneously — the results tell you directly.

What happens to my old accounts after I consolidate?

The consolidation loan pays out your existing debts — some lenders do this directly, others deposit funds to your account for you to pay manually. The old accounts still exist unless you actively close them. Close them. Leaving a credit card or store card open with a zero balance is available credit that can be spent again. Open accounts also count against your borrowing capacity for future applications. Close them promptly once cleared.

Can I add more debt to my consolidation loan later?

Generally no. A fixed personal loan has a set amount at origination. If you want to consolidate additional debt down the track, you'd need to refinance or take out a separate loan. This is another reason why closing old accounts matters — it removes both the temptation and the means to accumulate new debt alongside the consolidation loan.

What's the minimum amount worth consolidating?

As a practical guide: under $2,000, direct payoff is usually better. Between $2,000 and $5,000, consolidation may make sense if you have multiple high-rate accounts (20%+) and can access a meaningfully lower consolidation rate. Above $5,000 with two or more high-rate debts, consolidation is worth modelling seriously — which is exactly what this calculator is built for. Run the numbers for your actual situation; the answer is in the total interest comparison, not a rule of thumb.

One Rate. One Repayment. Do the Maths First.

Juggling credit cards, a personal loan, a store card, and a BNPL balance is expensive and exhausting. This calculator shows exactly what happens when you roll your debts into a single personal loan at one rate, one repayment, one due date — before you apply.

Who this calculator is for

Anyone carrying two or more debts — credit cards, store cards, personal loans, BNPL, or car loans — who wants to simplify repayments and find out if consolidation is worth it.
Borrowers whose current minimum repayments are barely covering interest and who want to see the true payoff timeline.
People who've been quoted a consolidation rate and want to stress-test it against their current debt stack before committing.

What it calculates

Current total monthly repayment across all debts vs a single consolidated repayment.
Total interest under the current arrangement vs total interest on the consolidated loan.
Monthly saving (or extra cost) if you consolidate.
Time to payoff under both scenarios — are you actually getting out of debt faster?

Why it matters

Consolidation only works if the numbers favour it. The most common mistake is focusing on the lower monthly repayment without checking what the extended term is costing in total interest. The term extension trap is how consolidation backfires — this calculator shows both the monthly and the total picture, side by side.

How this Debt Consolidation Calculator works

This calculator takes each debt you enter and projects its full payoff timeline individually — based on the outstanding balance, annual interest rate, and current monthly repayment. For each debt, it works out how many months it will take to reach a zero balance and how much interest you'll pay along the way. If your repayment is close to or below the monthly interest charge, the calculator flags it immediately: a repayment that doesn't cover interest means the debt never clears.

Once all individual debts are modelled, the calculator totals the balances (plus any establishment fee) to form the consolidated loan amount. It then applies your chosen interest rate and term using the standard principal-and-interest formula used by Australian lenders:

PMT = P × [r(1+r)ⁿ] / [(1+r)ⁿ − 1]

where P is the loan amount, r is the monthly rate (annual rate ÷ 12), and n is the total number of monthly repayments. This produces the fixed monthly repayment you'd make on the consolidated loan.

The comparison is direct: total interest on your current debts (at their individual rates, assuming you continue with the repayments you've entered) vs total interest on the consolidated loan (at the new rate, over the new term). The calculator shows the difference — a saving if consolidation is cheaper, or an extra cost if it isn't.

One limitation worth stating plainly: the current-debt projections assume you keep making the same monthly repayments without increasing them. If your credit card minimum repayment is barely covering interest, the total interest figure will look alarming — because it is. That's the real cost of minimum payments.

How to interpret your results

Monthly saving — useful for cash flow, not the whole story. A lower monthly repayment frees up budget now, but if you've achieved it by extending the term from 3 years to 7 years, you may pay significantly more interest over time.
Total interest saving — this is the number that matters. If consolidation saves money on a total-cost basis, you're genuinely better off. If it costs more in total, you're trading short-term relief for long-term expense.
The term extension trap — understand it before you sign. Extending a 2-year debt to a 5-year loan at a lower rate often produces a higher total interest cost. The calculator flags this directly with a warning when total interest on the consolidated loan exceeds total interest on your current debts.
Time to payoff — are you actually getting out of debt faster? Compare the weighted average payoff period of your current debts against the new loan term. If your cards would have cleared in 3 years but you're taking a 5-year consolidation loan, you've extended your debt timeline.
Worked example. Three debts: CC $8,000 @ 20% ($250/mth), PL $5,000 @ 14% ($180/mth), store $2,000 @ 22% ($100/mth). Current total interest ≈ $3,840 over ~4 years. Consolidate $15,000 at 10% over 3 years: monthly ≈ $484, total interest ≈ $2,415 — $46/month and $1,425 total saving. Change to 5 years at 16%: monthly drops to ≈$365 (looks better) but total interest rises to ≈$4,900 — $1,060 worse. The calculator flags that scenario in red.

How to get the most from debt consolidation

Close every account you consolidate. Consolidating a credit card but keeping it open is not consolidation — it's a loan with a reload option. Close the accounts. Cut the cards.
Choose the shortest term you can genuinely afford. Every additional year costs interest, even at a lower rate. Run 3 years vs 5 years and compare total interest — the monthly difference is often smaller than expected.
Your consolidation rate is the most important variable. A 2% difference can flip the outcome from saving money to costing more. Compare rates from multiple lenders before applying.
Include all your debts, not just the obvious ones. BNPL balances, store cards, and small personal loans all have a cost — even if BNPL appears interest-free, it carries scheduled obligations that affect cash flow and DTI.
Watch the fees. A $600 establishment fee on a $10,000 loan is 6% of the loan amount upfront. Always check the comparison rate (not just the advertised rate) — see the Comparison Rate Calculator.
Don't consolidate if the spending habit is still active. Consolidation clears the slate; it doesn't change the behaviour. Address the spending first — or alongside — the loan.

The win is not "a lower monthly repayment on a stretched timeline"; the win is "out of debt sooner and for less total interest, with the old accounts permanently closed."

Calculator assumptions

This calculator uses standard principal-and-interest amortisation — the same method Australian lenders use to calculate fixed repayments. It's accurate for fixed-rate loans with consistent monthly repayments. Results depend entirely on the inputs you provide: if your current interest rate or outstanding balance is approximate, the projections will be approximate. The current-debt projections assume you maintain the same monthly repayment for the full payoff period without increasing it. The consolidated loan projection assumes every repayment is made on time for the full term, with no additional repayments. The calculator does not account for ongoing monthly fees on current debts, potential rate changes on variable-rate products, or individual lender credit assessment outcomes.
