Formula & methodology

Formula used

Ordering (the snowball)

debts are repaid smallest balance first, regardless of interest rate

The snowball method targets the smallest balance first so a debt is cleared early. That is a behavioural strategy, not a mathematical optimum — ordering by highest interest rate instead (the "avalanche" method) costs less in total interest.

Interest accrual

interest = balance × (rate ÷ 12), applied to every debt each month

Every outstanding debt accrues interest each month before repayments are applied.

Payment pool

pool = Σ minimum repayments + extra repayment

The pool is applied to the target debt first; whatever is left flows to the next. As each debt clears, its minimum stays in the pool — this is what makes the snowball accelerate.

Variable definitions

Symbol	Meaning	Unit
balance	Debt balance. amount owing on each debt	AUD
rate	Interest rate. annual rate on each debt	% p.a.
min	Minimum repayment. the minimum required on each debt each month	AUD
extra	Extra repayment. additional amount you can put towards debt each month	AUD

Step-by-step calculation

1. List up to four debts
Balance, interest rate and minimum repayment for each.
2. Add whatever extra you can pay
This is the amount that drives the snowball.
3. Read the payoff time and total interest
If the payment pool cannot cover the interest accruing, the calculator reports that the plan never clears rather than showing a 50-year figure as though it were a plan.

Limitations

The snowball order is deliberate, not optimal. If your goal is to minimise interest paid, repay the highest-rate debt first instead.
Minimum repayments are held constant. On credit cards the required minimum falls as the balance falls, which slows real-world repayment compared with this projection.
Interest rates are held constant and no new borrowing is modelled.
This tool does not assess hardship options. If debt is unmanageable, the National Debt Helpline (1800 007 007) provides free, independent financial counselling in Australia.

How to Use This Calculator

List all your debts

Enter each debt's name, balance, interest rate, and minimum monthly payment. Include credit cards, personal loans, car loans, and any other debts.

Set your extra repayment

Decide how much extra you can put toward your debts each month – even $50–$100 makes a big difference.

View your snowball plan

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 Order
Your 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 Time
The number of months until you're completely debt‑free. This is your 'financial freedom date' – track your progress monthly.
Total Interest Paid
The combined interest across all debts over the payoff period. This number shows you why extra repayments matter so much.
Interest Saved
The 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.
