Debt consolidation is one of those financial moves that gets recommended constantly — and for good reason when applied correctly. But it's also one of the most misunderstood. Done wrong, it can cost you significantly more than doing nothing. Here's a clear-eyed look at when it works and when it doesn't.
What Is Debt Consolidation?
Debt consolidation means taking multiple debts — credit cards, personal loans, buy-now-pay-later balances, store cards — and combining them into a single loan with one monthly repayment.
The appeal is obvious: one repayment instead of five, a potentially lower interest rate, and a clear end date. The reality is more nuanced.
When Debt Consolidation Works
Lower Interest Rate
The fundamental requirement for consolidation to save you money is this: the new loan's interest rate must be lower than the weighted average rate across your existing debts.
Australian credit card rates typically sit between 18% and 22% per year. A personal loan through a competitive broker might land between 7% and 14% depending on your credit profile. If you're consolidating $15,000 of credit card debt at 20% into a personal loan at 10%, the maths works strongly in your favour.
Manageable Repayment Term
Consolidation only saves interest if the new loan term isn't dramatically longer than what remains on your existing debts. Spreading $15,000 over seven years instead of three will reduce your monthly payment — but increase total interest paid significantly.
Behavioural Discipline
Consolidation works best when paired with a commitment to not re-accumulate debt on the cards you've just paid off. Many people consolidate, then slowly rebuild balances on their cleared cards, ending up with both the consolidation loan and fresh card debt. If that's a risk for you, consider cancelling or reducing the limits on cleared cards.
When Debt Consolidation Doesn't Make Sense
Already on a Low Rate
If your existing debts are already at relatively low rates — a 0% balance transfer promotion, a low-rate personal loan — consolidating into a new loan at a market rate will cost you more, not less.
Extended Term Increases Total Cost
Even a lower rate can cost more if the term is extended far enough. Always model the total interest cost of the new loan against the total remaining interest on your current debts, not just the monthly repayment.
Fees Eat the Savings
Some consolidation loans carry establishment fees of $300–$600. Some existing loans charge break or early repayment fees. Make sure you account for all fees on both sides before deciding consolidation is worthwhile.
Secured vs Unsecured Risk
Converting unsecured debt (credit cards) into a secured personal loan (against an asset) may lower the rate, but it changes the risk profile. Defaulting on a secured loan can cost you the asset. Think carefully before putting property on the line to consolidate credit card debt.
How to Calculate Whether It Saves Money
The calculation is straightforward:
- Total remaining interest on current debts: for each debt, calculate remaining months × monthly interest charge and sum them.
- Total interest on consolidation loan: use a loan repayment calculator with the proposed rate, amount, and term.
- Subtract step 2 from step 1: if the result is positive, consolidation saves you that amount.
Use ClariFi's debt consolidation calculator — it handles this calculation automatically. Enter your existing debts, input a proposed consolidation rate, and see total interest saved and the reduction in monthly repayments side by side.
Credit Card Rates vs Personal Loan Rates in Australia
The rate differential between credit cards and personal loans is the engine that drives consolidation savings:
- Credit cards: 18%–22% p.a. (some rewards cards sit higher)
- Store/retail cards: often 22%–30% p.a.
- Personal loans via broker: 7%–16% p.a. for borrowers with good credit; 14%–25% for lower credit scores
- Buy-now-pay-later: technically 0% but late fees can be steep
If your credit score is strong, you're likely to access a personal loan rate well below what you're paying on cards — making consolidation compelling. If your credit score is poor, the gap may narrow or disappear.
