When you owe money on several accounts, the order in which you pay them matters. Two popular strategies differ in what they optimize: interest cost or motivation.
The avalanche method
List debts from highest interest rate to lowest. Pay the minimum on all of them and put every extra dollar toward the highest-rate debt. When it is gone, roll that payment into the next. Mathematically this costs the least interest.
The snowball method
List debts from smallest balance to largest. Pay minimums everywhere and attack the smallest balance first. Quick wins build momentum. Research on debt payoff suggests that progress on small balances helps many people stay committed.
Choosing and sticking with a plan
If the interest difference between methods is small, pick snowball for motivation. If you have a very high-rate card and strong discipline, avalanche saves more. A hybrid also works: knock out one tiny balance for a quick win, then switch to avalanche. Automate payments so the plan survives busy months.
Try the numbers
Use our Debt Snowball vs Avalanche Calculator to see this in practice. With its default example (Debt 1 balance: $1,800; Debt 1 APR: 8%; Debt 1 minimum: $50.00), it shows interest saved with avalanche: $615. Adjust the inputs to match your situation.
Key takeaways
- Avalanche minimizes interest; snowball maximizes early wins.
- Pay minimums on everything and focus extra cash on one target.
- The best method is the one you will follow consistently.
