A debt consolidation loan is a personal loan used to pay out several existing debts, such as credit cards and payday loans, leaving one repayment.

Also known as: consolidation loan, debt consolidation

Key points

  • The lender usually pays your existing creditors directly, so credit card and store accounts are closed or left at zero.
  • The new loan can be unsecured, or secured against a home or car, which usually costs less but puts the asset at risk.
  • Compare the comparison rate, not the headline rate, because it folds in most of the fees a lender charges.
  • Stretching the term lowers the monthly payment but can lift total interest, so check the total cost, not just the repayment.

Frequently asked questions

Is a debt consolidation loan bad for my credit?

Consolidation itself is fairly neutral. It can lower your credit utilisation and make repayments easier to meet. The application does trigger a credit enquiry, and closing old accounts can change your credit history, but how you manage the new loan matters most.

Is interest on a consolidation loan tax deductible?

Interest on a personal consolidation loan is generally not deductible, because the borrowing is not producing assessable income. The treatment can differ where the funds are used for an income producing purpose. Check the ATO's guidance or speak with your accountant.

Can I consolidate debt with bad credit?

It is harder, and the options narrow. Some unsecured lenders will still look at it, and a secured loan may be available, though pricing is higher. Free advice from the National Debt Helpline is worth getting before you take on a new loan.

What is the difference between secured and unsecured consolidation?

A secured consolidation loan is backed by an asset such as a home or car, which usually brings the rate down but puts that asset at risk if you fall behind. An unsecured loan has no collateral, so it costs more but nothing is pledged.

Do I need to close my credit cards after consolidating?

Not always, though leaving the limits open is a risk if the balances creep back up. Reducing the credit available to you lowers your utilisation, which helps your credit file. Some lenders make closing the accounts a condition of the loan.
