How Debt Payoff Strategies Work

What's the difference between snowball and avalanche?

The debt snowball method pays off your smallest balance first, giving you quick psychological wins that build momentum. The debt avalanche method targets the highest interest rate first, which minimizes total interest paid over the life of your debts. Both methods make minimum payments on all debts and direct extra payments to one priority debt at a time.

How much extra should I pay toward debt?

Even an extra $100-200 per month can dramatically reduce your payoff timeline and total interest. The key is consistency — any amount above minimums accelerates payoff because 100% of extra payments go toward principal. Review your budget for discretionary spending that could be redirected, and consider putting windfalls like tax refunds toward debt.

Which method saves more money?

The avalanche method always saves more in total interest because it prioritizes high-rate debt. However, the snowball method can be more effective in practice because the early wins keep people motivated. The difference between methods is often smaller than people expect — the most important factor is simply making consistent extra payments regardless of which strategy you choose.
