Frequently Asked Questions

How much faster is the avalanche method?

The avalanche method typically saves 2-5% of your total debt in interest charges compared to the snowball method. For someone with $40,000 in debt, this could mean saving $800-$2,000 and becoming debt-free several months earlier.

Should I use avalanche or snowball?

Use avalanche if you're motivated by saving money and can stay disciplined without quick wins. Use snowball if you need psychological momentum and quick victories to stay motivated. The best method is the one you'll actually stick with.

What if I can't afford extra payments?

Even without extra payments, the avalanche method still works - just focus any freed-up money (after paying off a debt) on the highest-rate remaining debt. Also consider balance transfer cards, debt consolidation, or negotiating lower rates with creditors.

Should I pay off debt or save for emergencies first?

Most experts recommend building a small emergency fund ($1,000-$2,000) first, then aggressively paying off high-interest debt. This prevents you from going deeper into debt when unexpected expenses arise. Once debt is paid off, build a full 3-6 month emergency fund.
