Two strategies โ which is right for you?
โ๏ธ
Avalanche Method
Pay minimum on all debts. Attack the highest interest rate first. Mathematically optimal โ saves the most money. Best for disciplined people who don't need quick wins.
โ
Snowball Method
Pay minimum on all debts. Attack the smallest balance first. Not mathematically optimal but provides psychological wins. Better for people who need motivation.
Use the Debt Race calculator to compare both strategies with your actual debts
Avalanche or snowball โ which is actually better?
Mathematically, avalanche (highest rate first) always saves more money. But research shows snowball (smallest balance first) leads to higher debt-freedom rates because quick wins maintain motivation. If you're disciplined, use avalanche. If you've started and stopped debt payoff plans before, use snowball. The best method is the one you actually stick to.
Should I invest while paying off debt?
Depends on the interest rate. High-interest debt (credit cards at 18โ22%) โ pay off first, always. It's a guaranteed 20% return. Medium debt (personal loans 8โ12%) โ consider investing in super via salary sacrifice while paying minimum on debt, since super contributions are tax-advantaged. Low-rate debt (HECS, some mortgages below 6%) โ investing in index funds makes mathematical sense, though personal preference matters.
Does debt consolidation actually help?
Only if three things are true: the new rate is genuinely lower, you don't extend the term so long that total interest exceeds what you'd pay separately, and you cut up the cards so you can't accumulate more debt. Many people consolidate, feel relief, and then run the cards back up โ ending up with both the consolidation loan AND new card debt. The calculator shows the math, but the discipline comes from you.
