Snowball vs Avalanche: Which Debt Payoff Strategy Wins?
Both the Snowball and Avalanche methods use the same core mechanic: you make minimum payments on all debts, then throw any extra money at one targeted debt. The difference is which debt you target first.
The Snowball Method
Made famous by Dave Ramsey, the Snowball method targets your smallest balance first. Once that debt is paid off, you roll the freed minimum into the next smallest. The psychological wins from clearing debts quickly keep many people motivated — research shows this behavioral advantage leads to higher completion rates.
The Avalanche Method
The Avalanche method targets your highest interest rate first — minimizing the total interest you pay. Mathematically, this is always the cheaper strategy. The savings vs. Snowball are typically $500–$3,000 depending on your debt mix and rates.
Which Should You Choose?
- Choose Snowball if you need quick wins to stay motivated, or if your balances are similar in size.
- Choose Avalanche if you're disciplined and want to minimize total cost.
- Either method beats paying minimums only — both result in debt freedom years sooner.
