Debt Snowball (lowest balance first)
List debts from smallest balance to largest. Pay minimums on everything, then throw every extra dollar at the smallest balance. When it’s gone, roll that payment into the next smallest.
- Strength: Quick wins. Paying off a $400 store card in a month or two feels real.
- Psychology: Momentum and visible progress keep people going when motivation dips.
- Trade-off: You may pay more interest if high-APR debts sit longer.
Debt Avalanche (highest APR first)
Same minimums-plus-extra structure, but order by interest rate (highest first). You attack the most expensive debt first.
- Strength: Mathematically optimal. Lowest total interest over the life of the plan.
- Psychology: Progress can feel slow if the highest-rate debt is also the largest.
- Best when: You’re disciplined and the rate gap between debts is large.
Which one wins on paper?
Avalanche almost always costs less interest. The difference is often a few hundred to a few thousand dollars depending on balances and rates. Snowball can finish a small debt months earlier, which some people value more than the interest savings.
There is no universal “best.” The method you stick with beats the optimal method you abandon after three months.
Hybrid approaches
Many people knock out one or two tiny balances with snowball for the win, then switch to avalanche. Others use avalanche but keep a small “victory fund” for the lowest balance. Our calculator lets you compare both pure strategies side-by-side with the same debts and extra payment so you can see the exact dollar and month difference.
How to decide in 60 seconds
- If high-APR debts are also large and you care most about total cost → Avalanche.
- If you have several small balances and struggle with consistency → Snowball.
- If you’re unsure → run both in the calculator. The winner banner shows interest and months saved.
