Escaping High-Interest Debt
Avalanche vs snowball — two proven ways to clear debt, and which finishes faster.
If you’re juggling multiple debts, two proven methods structure your payoff: the avalanche and the snowball. Both say “pay minimums on everything, then throw all spare money at one target debt” — they differ only in which debt you attack first.
- Avalanche — attack the highest-interest debt first (then the next highest, etc.). Mathematically optimal: pays the least total interest, finishes fastest.
- Snowball — attack the smallest balance first (regardless of rate), for a quick win, then roll to the next. Behaviourally motivating.
The real lesson is the tension between math and psychology — and knowing which one you need. The avalanche is mathematically superior: by killing the highest-rate debt first, you minimise total interest and finish soonest, saving the most money. But debt payoff is a behavioural marathon, and the snowball — clearing the smallest balance first for a fast, motivating win — keeps many people going when pure math wouldn’t. The honest guidance: use the avalanche if you’re disciplined and motivated by saving money; use the snowball if you need early wins to stay the course — because a method you stick to beats a “better” method you abandon (the same adherence-beats-optimality lesson from budgetingA plan for how you’ll spend and save your income.). Either way, the structure is identical and powerful: minimums everywhere + all surplus on one target + roll the freed-up payment to the next debt as each clears (the “snowball/avalanche” effect accelerates as you go). Pick the version that matches your temperament, and start — momentumBuying recent winners and avoiding recent losers., not perfection, gets you debt-free.
- Both methods — pay minimums on all, throw all surplus at ONE target, roll the freed payment to the next as each clears.
- Avalanche — highest rate first; least total interest, fastest, mathematically best (for the disciplined).
- Snowball — smallest balance first; quick motivating wins (for those who need momentumBuying recent winners and avoiding recent losers.).
- The rule — adherence beats optimality; pick the one you’ll stick to and start now.
ExampleYou owe a ₹40k card at 40%, a ₹1L personal loanAn unsecured loan at a high interest rate. at 14%, and a ₹20k BNPL at 24%. Avalanche: hit the 40% card first (saves the most interest). Snowball: clear the ₹20k BNPL first for a fast win, then roll on. Avalanche saves more money; snowball may keep you motivated. The best choice is whichever you’ll actually finish — both beat paying minimums forever.
Key takeawayTo escape multiple debts: pay minimums on all, throw surplus at ONE, and roll the freed payment to the next as each clears. Avalanche (highest rate first) is mathematically best — least interest, fastest; snowball (smallest balance first) gives motivating early wins. Pick the one you’ll stick to — adherence beats optimality.
FAQs
Avalanche or snowball — which should I choose?
If you’re motivated by saving the most money and can stay disciplined, choose *avalanche* (highest interest first) — it’s mathematically optimal. If you need visible early wins to keep going, choose *snowball* (smallest balance first). The difference in total cost is usually modest; the bigger risk is quitting, so pick whichever keeps you consistent. The best plan is the one you complete.
