Is Debt Consolidation a Good Idea? Pros and Cons

Debt consolidation is a good idea when it lowers the interest rate you're paying across your debts and you don't take on new borrowing afterwards. Australians currently owe $21.6 billion in credit card debt that's accruing interest at an average of 18.59% p.a., while a personal loan for consolidation typically sits between 7% and 12%. But a lower rate alone doesn't tell the whole story, and in some situations consolidation can cost you more.

Why debt consolidation is on more people's radar in 2026

Australia's household debt-to-income ratio sits at around 190%, among the highest in the OECD. At the same time, the cost of servicing that debt has climbed. The RBA's April 2026 data shows 12.18 million credit card accounts in the country, with nearly half of all balances accruing interest. That's a lot of Australians paying close to 19% on revolving debt while personal loan rates sit roughly 8 percentage points lower. It's no surprise that debt consolidation is now the most common reason Australians take out a personal loan.

What debt consolidation actually does

Debt consolidation rolls multiple debts into a single loan with one repayment. Instead of juggling a credit card, a buy now pay later balance, and maybe a store finance plan, you take out one debt consolidation loan and use it to pay everything off.

The appeal is straightforward: one repayment date, one interest rate, and a fixed end date. But the real question isn't whether consolidation simplifies your finances. It's whether it saves you money.

When debt consolidation works in your favour

Your blended interest rate drops

If you're carrying $15,000 across two credit cards at 18% to 22% and you consolidate into a personal loan at 9.5%, you're paying roughly half the interest. On $15,000, that's the difference between around $2,800 and $1,425 in interest over the first year alone.

You get a fixed repayment schedule

Credit cards let you pay the minimum, which is how people stay in debt for decades. A consolidation loan has a fixed term, typically 2 to 7 years, with structured repayments that actually clear the balance. You know exactly when you'll be debt-free.

You stop paying multiple fees

Annual fees, late payment fees, account-keeping fees. If you're running three or four credit products, the fees stack up. One loan means one set of fees.

When debt consolidation works against you

You extend the term to lower the payment

This is the most common trap. Say you owe $25,000 on credit cards and you're paying $800 a month. You consolidate into a 7-year personal loan and your monthly repayment drops to $430. That feels like relief, but you've just added years of interest.

This matters because people consolidate for different reasons. Some want to reduce the total interest they pay. Others want to reduce the monthly repayment to free up cash flow. These two objectives pull in opposite directions. Extending the term lowers your monthly cost but increases total interest. Shortening the term does the reverse.

Before you consolidate, decide which objective matters more. Then check that the loan you're being offered actually delivers it.

You keep using the credit cards

Consolidation only works if you close or stop using the accounts you paid off. AFSA data shows 48.9% of new debtors hold buy now pay later liabilities, and the pattern is the same with credit cards. If you consolidate $20,000 of card debt into a loan and then rebuild the card balances, you end up with more debt than you started with.

The rate isn't actually lower

Not everyone qualifies for a competitive consolidation rate. If your credit history has defaults or missed payments, you may be offered 15% or higher on a personal loan. At that point, consolidation simplifies your repayments but doesn't save you interest. Check the comparison rate, not just the headline rate.

The numbers: what consolidation actually saves

The savings are significant at standard personal loan rates. But the table assumes you repay over the same 3-year term. Stretch the personal loan to 7 years and the total interest on $25,000 climbs from $4,025 to around $9,600, nearly wiping out the benefit.

Alternatives to consider first

Debt consolidation isn't the only option, and it's not always the best first step.

Hardship provisions

If you're struggling to make repayments, your existing lenders are required to consider hardship arrangements. This can include reduced payments, paused interest, or extended terms. It costs nothing to ask and doesn't require a new loan.

Balance transfer cards

Some credit cards offer 0% balance transfer periods of 12 to 24 months. If your total debt is under $10,000 and you can pay it off within the promotional period, this can work out cheaper than a consolidation loan. The risk is the revert rate, which can exceed 20%.

National Debt Helpline

The National Debt Helpline (1800 007 007) provides free financial counselling. If your debts feel unmanageable, a counsellor can help you assess whether consolidation, a debt agreement, or another path makes the most sense. In 2024-25, creditors in formal debt agreements received 47.75 cents per dollar owed, which shows how much can be resolved through structured negotiation.

How to tell if consolidation is right for you

Run through these five questions before you apply.

1. Is your combined interest rate higher than what a personal loan would cost? Check the comparison rate, not the advertised rate.
2. Can you commit to a repayment term that actually saves you money? Shorter is better. Match the term to the debt, not to what makes the monthly payment comfortable.
3. Will you close or freeze the accounts you're paying off? If not, consolidation is likely to make things worse.
4. Is your credit profile strong enough for a competitive rate? If you're being quoted above 15%, the savings shrink fast.
5. Have you spoken to your existing lenders about hardship? Start there. It's free and doesn't create a new credit enquiry.
