Debt Consolidation Mistakes Australians Make and How to Avoid Them

Updated 31 July 2026 · Loans and credit

A Debt Consolidation Calculator gives a fast answer, but the answer is only as good as what goes in. These are the mistakes we see most often with debt consolidation calculations in Australia, and how to avoid them.

1. Not planning for a balloon payment

A balloon lowers repayments now but leaves a large lump sum to pay or refinance later.

2. Focusing on the monthly repayment

A longer term lowers repayments but raises total interest. Look at the total cost.

3. Paying only the minimum

Minimum repayments on credit cards can take decades and cost more than the original balance.

4. Ignoring fees

Establishment, monthly and early repayment fees can outweigh a lower interest rate.

5. Overlooking the detail that matters most here

Consolidating into a longer term can lower repayments but raise total interest. Keep the term the same or shorter.

How the total saving changes with average current rate

A common mistake is getting one input slightly wrong. Here is what happens to the total saving when “Average current rate (%)” is off by up to 20% in either direction, with everything else held steady.

Average current rate (%)	Total saving
14	$794.71
16	$1,499.88
18	$2,216.54
20	$2,944.60
22	$3,683.94

At 14 the result is $794.71; at 22 it is $3,683.94. If a small change in this input moves the answer a lot, it is worth double-checking that figure before you rely on the result.

A quick sense check

Both options are repaid over the same term. Fees are added to the new loan. With typical inputs the calculator returns total saving of $2,216.54. If your own result looks wildly different, check that each figure is in the right unit and period (weekly, monthly or yearly) before drawing conclusions.
