How to Use This Calculator
Enter each debt's name, balance, interest rate, and minimum monthly payment. Include credit cards, personal loans, car loans, and any other debts.
Decide how much extra you can put toward your debts each month – even $50–$100 makes a big difference.
The calculator orders debts from smallest to largest balance. It shows your payoff timeline, total interest, and how much you save by using this method.
Understanding Your Results
- Snowball OrderYour debts are sorted from smallest balance to largest. You'll focus all extra payments on the smallest debt first – this gives you quick wins and keeps motivation high.
- Total Payoff TimeThe number of months until you're completely debt‑free. This is your 'financial freedom date' – track your progress monthly.
- Total Interest PaidThe combined interest across all debts over the payoff period. This number shows you why extra repayments matter so much.
- Interest SavedThe amount of interest you save by making extra repayments compared to paying only minimums – often thousands of dollars.
Key Tips
- ✓Start with the smallest debt first – the psychological boost of a 'win' keeps you going.
- ✓Increase your extra repayment whenever you get a pay rise, tax refund, or bonus – even a small increase accelerates progress.
- ✓Avoid taking on new debt while repaying – cut up or freeze credit cards if needed.
- ✓Consider debt consolidation if it lowers your average interest rate – but watch out for fees.
- ✓Automate your extra repayments so you never miss a payment – set up a direct debit.
- ✓Tell someone about your debt‑free goal – accountability helps you stay on track.
- ✓Track your progress visually – use the calculator's timeline to see each debt disappear.

Debt Snowball Method – The Complete Australian Guide (2026)
What Is the Debt Snowball Method?
The debt snowball is a debt repayment strategy where you list all your debts from smallest balance to largest, regardless of interest rate. You make minimum payments on all debts, then put every extra dollar toward the smallest debt until it's gone. Once cleared, you roll that payment amount into the next smallest debt – creating a 'snowball' effect. It was popularised by Dave Ramsey and works brilliantly for Australians because it focuses on behaviour, not just math.
Why the Snowball Method Works So Well
Most Australians struggle with debt because they lack motivation, not math skills. The snowball method gives you quick wins – paying off a small debt in a few months provides a psychological boost that keeps you going. Research shows that people who use the snowball method are more likely to stay on track and become debt‑free than those who use the avalanche method (which tackles highest interest first). In Australia, where credit card debt is common, this approach can be life‑changing.
Snowball vs. Avalanche – Which Should You Use?
The avalanche method saves you the most money in interest (by prioritising highest‑rate debts), but it can feel slow because high‑balance debts take longer to clear. The snowball method prioritises small balances, giving you a dopamine hit each time you cross a debt off your list. For most Australians, the snowball method is more effective because staying motivated is the key to success. Use our calculator to model both – choose the one that excites you.
Typical Australian Debt Interest Rates (2026)
As of 2026, Australian credit cards average 19‑22% p.a., personal loans 8‑15%, and car loans 6‑10%. Store cards and buy‑now‑pay‑later often exceed 20%. The snowball method works with any interest rates – but knowing your rates helps you understand the cost of waiting. Use this calculator to see exactly how much interest you'll pay with different strategies.
How to Find Extra Money for Debt Repayment
Review your budget – where can you cut back? Cancel unused subscriptions, reduce dining out, shop for cheaper insurance. Consider a side hustle or selling unused items. Apply any tax refund, bonus, or windfall to your smallest debt. Even $50 per month extra can shave months off your payoff time and save hundreds in interest.
Avoiding New Debt – The Trap to Avoid
While repaying, avoid taking on new debt – that includes new credit cards, 'interest‑free' purchases, or using buy‑now‑pay‑later schemes. If you must use credit, treat it like a debit card and pay it off in full each month. Our budgeting calculator can help you plan your spending to stay on track.
How to Use This Calculator to Build Your Debt‑Free Plan
Enter each debt you have – name, balance, rate, and minimum payment. Set your monthly extra repayment – be realistic but ambitious. The calculator will show you the order to pay them off and your total timeline. Review the results, then commit to the plan. Update the calculator monthly to track your progress – you'll be amazed at how quickly debts disappear.
