Avalanche vs. Snowball: Two Ways To Pay Down Debt

When you owe money on several accounts, the order you attack them in changes both the total interest you pay and how likely you are to finish. Two methods dominate the conversation, and they optimize for different things.

Both start the same way

Make the minimum payment on every debt, always. Missing a minimum triggers fees and damages your credit, which makes everything harder. Then take whatever extra money you have and direct all of it at one target debt. The methods differ only in which debt you target.

The avalanche method

Target the debt with the highest interest rate first, regardless of balance. When it is cleared, roll that entire payment into the next-highest rate.

This is mathematically optimal. It always produces the lowest total interest and the shortest payoff time. Its weakness is psychological: if your highest-rate debt is also your largest, you may go a long time without visibly finishing anything.

The snowball method

Target the smallest balance first, regardless of interest rate. Clear it, then roll that payment into the next smallest.

This costs more in interest, sometimes noticeably. In exchange you close accounts quickly, and each closed account frees a payment and provides evidence that the plan is working. Research on debt repayment has found that people following the snowball are often more likely to stay with it.

Choosing between them

• If your rates vary widely — a 24% card next to a 5% loan — avalanche saves enough to be worth the patience
• If you have several small balances and have abandoned repayment plans before, snowball buys momentum
• A hybrid works: clear one or two tiny balances for the win, then switch to avalanche

The best method is the one you will still be running in eight months. A plan that is 5% less efficient and actually gets finished beats an optimal plan you quit.

One thing to check first

Before choosing, confirm whether any of your debts carry deferred interest or a promotional rate that expires. Those deadlines can override both methods and should be handled first.
