Frequently Asked Questions
Should I pay off debt or invest?
The decision between paying off debt or investing depends on the interest rate of your debt versus your expected after-tax investment return. A credit card at 19% p.a. costs more than most investment returns can reliably guarantee, so paying it off first is effectively a risk-free 19% return. A mortgage at 6% is more nuanced: after tax deductions, the effective cost might be around 4.5%, and a diversified portfolio might average 7% pre-tax, making investing alongside mortgage repayment reasonable for some people.
What is the debt avalanche method?
The debt avalanche method targets your highest-interest debt first while making minimum payments on all other debts. Once the highest-interest debt is fully paid off, you roll that entire payment into the next highest-interest debt, creating an accelerating payoff snowball. This mathematically minimises the total interest you pay over time and is generally the fastest way to become debt-free when interest rates vary across your debts.
What is the debt snowball method?
The debt snowball method targets your smallest balance first while making minimum payments on all other debts. The psychological win of eliminating a debt relatively quickly provides motivation to stay committed to your payoff plan. While total interest paid with the snowball method is higher than the avalanche approach, behavioural consistency often leads to faster actual debt elimination, particularly for people who have struggled with debt in the past and need early wins to maintain momentum.

Is it worth consolidating my debt?
Debt consolidation can help by simplifying multiple payments into one and potentially lowering your weighted average interest rate. A balance transfer to a 0% p.a. credit card (common in Australia with 12-24 month promotional periods) can save significant interest if you can pay off the balance before the revert rate applies. However, consolidation only works if you address the underlying spending habits that created the debt, otherwise you risk accumulating new debt on top of the consolidated loan.
What is a hardship arrangement?
If you cannot meet your debt repayments, contact your lender as soon as possible. Australian banks and credit providers have formal hardship provisions under the National Credit Code and may offer a temporary reduction in payments, interest rate reduction, or payment pause for an agreed period. A hardship arrangement is recorded on your credit file and may affect your credit rating, but it is far better than defaulting. Financial counsellors (free through Services Australia) can help negotiate on your behalf.
How does debt affect my credit score?
Several factors related to debt impact your credit score in Australia: high debt levels relative to your available credit limits (called credit utilisation), missed or late payments, defaulting on any debt, and having too many credit applications in a short period (each enquiry is recorded). Your credit file in Australia can be accessed through Equifax, Experian, or Illion. Maintaining credit utilisation below 30% and making all payments on time are the most effective ways to protect and improve your credit score.
