Snowball vs Avalanche: Which Strategy Wins?

When paying off multiple debts, the order matters. The two most popular strategies are the debt snowball and debt avalanche methods, and they take completely different approaches.

The Snowball Method

With the snowball method, you list your debts from smallest to largest balance. You pay minimums on everything, then attack the smallest debt with any extra money you have. Once that's paid off, you roll its payment into the next smallest debt—creating momentum as your payments "snowball" toward bigger debts.

This method is psychologically powerful. Quick wins keep you motivated, and many people find success with it because the behavior change is easier to maintain.

The Avalanche Method

The avalanche method targets debts by interest rate, starting with the highest rate first. Mathematically, this saves the most money because you're eliminating expensive debt faster. However, it can feel slower at first if your highest-rate debt also has a large balance.

Which Should You Choose?

Choose snowball if motivation is your challenge. Choose avalanche if you want to minimize total interest paid. Some people use a hybrid: snowball for psychological momentum, then switch to avalanche once they're confident they'll stick with it.

FAQ

What's the main difference between snowball and avalanche?

Snowball pays off smallest debts first (psychological wins). Avalanche targets highest interest rates first (saves the most money). Both use the same extra payment amount; only the order changes.

Can I switch strategies midway?

Absolutely. Many people start with snowball for motivation, then switch to avalanche once they have momentum. The calculator shows you both paths so you can make an informed choice.

What if my income changes?

Recalculate with your new extra payment amount. Even small increases in extra payment can shorten your timeline significantly.

Does this account for balance transfer offers?

No. This calculator assumes you keep paying existing debts at their current rates. If you transfer balances, recalculate with the new rate.
