Avalanche vs Snowball: Which is Better?

The honest answer: it depends on how you're wired.

Mathematically optimal

Debt Avalanche

Highest interest rate first

Pay minimums on all debts, then throw every extra dollar at the debt with the highest interest rate. Once it's gone, roll that payment to the next-highest rate.

Saves the most total interest. Best for people who are motivated by numbers and can stay disciplined even when progress feels slow.

Psychologically powerful

Debt Snowball

Smallest balance first

Pay minimums on all debts, then throw every extra dollar at the smallest balance. Once it's cleared, roll that payment to the next smallest.

Gets you wins faster. The psychological momentum of eliminating accounts keeps many people on track when avalanche feels abstract.

Avalanche saves more money. Snowball wins on psychology.

The best method is the one you'll stick to. Start with whichever keeps you motivated.

5 Ways to Pay Off Debt Faster in Australia

1

Add $50–100 extra per fortnight

Even small amounts compress your timeline significantly. $100/fortnight extra on a $10,000 personal loan can cut 18+ months.

2

Balance transfer credit cards

0% intro offers (12–24 months) let you pay down principal without accruing new interest. Transfer fees are usually 1–3% — worth it if the rate is high.

3

Pause super salary sacrifice

If your debt rate exceeds 7%, temporarily redirecting salary sacrifice to debt repayment is often the mathematically better move.

4

Sell unused assets

Unused gym equipment, electronics, furniture. Even $500–2,000 applied as a lump sum payment saves months of interest.

5

Automate extra payments

Set up a direct debit for your minimum plus a fixed extra amount the day after payday. Remove the temptation to spend it.
