How the Snowball and Avalanche Methods Work

Both methods have you make minimum payments on all debts, then direct any extra money toward one targeted debt. The Snowball method targets the smallest balance for quick wins. The Avalanche method targets the highest interest rate to minimize total interest paid.

How to Pay Off Debt Faster

The most impactful strategy is to increase your extra payment amount. Even $50–$100 more per month can shave months or years off your payoff timeline. Consider cutting discretionary spending, selling unused items, or picking up a side income. Check your Financial Health Score to see how debt reduction fits into your broader financial picture.

Frequently Asked Questions

The snowball method prioritizes paying off your smallest balance first while making minimum payments on all other debts. Once the smallest debt is eliminated, you roll that payment into the next smallest. This method provides quick psychological wins that keep you motivated.

The avalanche method prioritizes paying off debts with the highest interest rate first. This minimizes total interest paid over time, saving you the most money mathematically. However, it may take longer to see your first debt eliminated.

Mathematically, avalanche saves more money. But research shows many people are more successful with snowball because the quick wins keep them motivated. If the interest difference is small (under $500), go with snowball. If it's significant, avalanche is worth the discipline.

It depends on your interest rate and payments. At 20% APR with $300/month payments, it takes about 44 months and costs $3,100 in interest. Increasing to $500/month cuts it to 23 months and $1,400 in interest. Use the calculator above with your exact numbers.

Even an extra $50–$100/month can dramatically shorten your payoff timeline. The key is consistency. Our calculator shows exactly how extra payments impact your debt-free date and total interest. Start with whatever you can afford and increase as possible.

Yes. Paying off debt reduces your credit utilization ratio, which is 30% of your FICO score. Paying off revolving debt (credit cards) has the biggest impact. Installment loans (car, student) have a smaller effect but still help your overall credit profile.
