Debt Consolidation Loans in Australia: How Lenders Actually Assess Them

The short answer

Key takeaway: A debt consolidation loan isn't a different category of loan in a lender's eyes — it's a personal loan with a specific purpose. The DTI and affordability checks are identical to any other application. What changes your outcome is whether the accounts you're consolidating actually close.

What a debt consolidation loan actually is

`Debt consolidation` — replacing several existing debts with one new loan — is a personal loan like any other, used to pay out multiple existing accounts (credit cards, car loans, other personal loans, sometimes BNPL) so you're left with a single repayment instead of several.

The appeal is obvious: one repayment date, often a lower combined interest rate than juggling multiple products, and less to track. But from a lender's side, a consolidation loan goes through exactly the same assessment as any other personal loan application — the same DTI check, the same affordability formula, the same credit score bands. There's no separate, easier pathway for "debt consolidation" as a category.

How lenders actually assess a consolidation application

The application is assessed on your position at the time you apply — which includes the debts you're planning to pay out, because they haven't been paid out yet. A lender doesn't pre-emptively treat your existing credit card as gone just because you've told them the new loan will close it.

Credit cards

Most lenders don't look at what you actually owe on a card — they assess a percentage of the total limit as a standing monthly obligation, regardless of whether you carry a balance or pay it off in full every month. LoanClarify's calculators use 3.5% of the total limit, so a $10,000 limit is treated as roughly $350 a month in obligations, even against a $0 statement balance. A credit card is a standing offer of credit you could draw on at any time, which is why the limit — not the balance — is what gets assessed. See Does Your Credit Card Limit Affect Your Personal Loan Application? for the full mechanics.

The debts you're consolidating

This is the part that catches people out, and where lender approach genuinely varies:

• Conservative approach — some lenders count your existing balances and repayments in full during assessment, treating the debts you're consolidating as still open, because at the point of assessment, they are. If your DTI is already close to 50% before consolidating, adding a new loan repayment on top of still-open existing accounts can push you over the line during the assessment itself — even though the plan is for those accounts to disappear shortly after.
• Post-consolidation approach — other lenders assess your position as it will be after settlement, crediting the fact that the debts you're consolidating will be paid out and closed as a condition of the new loan, and counting only the new consolidated repayment against you.

Which approach a specific lender takes generally isn't stated in their marketing — it's worth asking directly, or working with a broker who knows which lenders on their panel take the more favourable view for a consolidation scenario like yours.

What actually moves your numbers

• Closing the accounts you consolidate. A credit card limit stops counting in your DTI at 3.5% per month only once the card is closed — not once the balance hits zero. See Does Your Credit Card Limit Affect Your Personal Loan Application? for the full mechanics.
• Replacing several repayments with one. If the new loan's monthly repayment is genuinely lower than the combined repayments it replaces, your DTI numerator drops — which is the actual, measurable improvement lenders can see.
• Reducing your total number of open credit lines. Fewer open accounts, even at $0 balance, is a cleaner profile — but again, only once they're closed.

A worked example

This example follows the conservative approach — the one most worth planning around, since it's the harder case. Someone earning $80,000 gross annually ($6,667/month) is carrying:

• Two credit cards, $8,000 and $6,000 limits → assessed at 3.5% = $280 + $210 = $490/month
• A car loan repayment of $380/month
• A personal loan repayment of $310/month

``` Existing debt repayments = $490 + $380 + $310 = $1,180 DTI = ($1,180 ÷ $6,667) × 100 = 17.7% ```

They apply for a $14,000 consolidation loan to pay out the car loan and personal loan, with an estimated new repayment of $420/month, and plan to close both cards.

At the point of application — before anything is closed:

``` Total debt repayments = $490 (cards, still open) + $380 (car loan, still open) + $310 (personal loan, still open) + $420 (new loan) = $1,600 DTI = ($1,600 ÷ $6,667) × 100 = 24.0% ```

This still passes comfortably under 50%, so the application itself isn't at risk here. But notice the number didn't drop during assessment — it went up, because the old accounts hadn't closed yet. A lender taking the post-consolidation approach would skip straight to the after-settlement figure below instead. Under the conservative approach, though, the improvement only shows up after settlement, once the car loan and personal loan are paid out and gone:

``` Total debt repayments after settlement = $490 (cards still open, unless also closed) + $420 (new consolidation loan) = $910 DTI = ($910 ÷ $6,667) × 100 = 13.7% ```

If they also close both cards as part of the plan, the $490 disappears entirely and DTI drops further still. The consolidation genuinely improved their position — but only because the old accounts were actually closed, not just paid down.

What lenders actually look for

• Evidence the old accounts will close, not just reduce. Some lenders ask for confirmation that consolidated accounts are being closed as a condition of approval, precisely because a paid-but-open card doesn't reduce risk from their perspective.
• Whether the consolidation improves affordability or just extends the debt. A longer loan term can lower the monthly figure while increasing total interest paid — lenders (and you) should weigh that as a real trade-off, not a free win.
• Your DTI at the point of application, not your projected DTI after settlement. This is the detail that surprises people most — see the worked example above.

The T2 Borrowing Capacity Calculator shows your DTI at your current position. Run it once with your existing debts, then again with your planned consolidation loan in place of the accounts you'd close, to see the real before-and-after — not just the number a lender sees mid-application.
