Snowball vs Avalanche: Which Debt Payoff Method Should You Use?
If you carry multiple debts — credit cards, a car loan, student loans, personal loans — the order in which you attack them changes how much interest you pay and how long you stay in debt. There are two famous strategies, and almost every article picks a side. This calculator does something better: it runs both strategies on your actual debts and shows the real difference in dollars and months.
The Debt Snowball Method
List debts from smallest balance to largest. Pay minimums on everything, then throw every spare dollar at the smallest balance. When it's gone, roll its payment into the next smallest. Popularized by Dave Ramsey, the snowball wins on psychology: quick wins keep you motivated.
The Debt Avalanche Method
List debts from highest interest rate to lowest. Attack the most expensive debt first. Mathematically, the avalanche always pays the same or less total interest — it is the optimal strategy on paper.
The Honest Answer
For many real-world debt profiles, the difference between the two methods is smaller than people expect — sometimes under a few hundred dollars. When the gap is small, choose the snowball for motivation. When the gap is large (typically when you have a high-rate credit card with a big balance), the avalanche is clearly worth it. That is exactly what this tool tells you: the precise gap for your numbers, so you can decide with facts instead of opinions.
Tips to Accelerate Either Strategy
Call your card issuer and ask for a rate reduction — it works more often than people think. Consider a 0% balance transfer for high-rate cards if the fee is under the interest saved. And any windfall (tax refund, bonus) applied to your target debt shortens the timeline dramatically.
