What is Debt Snowball vs Debt Avalanche?
The debt snowball and debt avalanche are the two most popular debt repayment strategies. Snowball (smallest balance first) provides psychological momentum through quick wins. Avalanche (highest interest first) minimizes total interest paid. Both are far better than making only minimum payments. This calculator models both approaches side-by-side so you can see the exact time and interest difference for your specific debt situation.
Which is Better for You?
The right choice depends on your specific situation. Here are the most common decision scenarios:
You need psychological motivation to keep going
Quick wins from paying off small debts first provide dopamine hits that keep you motivated. Kellogg School research (2012) found this approach increases the likelihood of becoming debt-free.
You want to minimize total interest paid
Paying highest-interest debt first is mathematically optimal. On $25,000 in debt, the avalanche method typically saves $500-$2,000 in interest compared to snowball.
Your debts have similar interest rates
When rates are close (within 2-3%), the interest savings from avalanche are minimal. The motivational benefit of quick wins makes snowball the better practical choice.
You have one high-interest debt that's also the largest
When your biggest debt also has the highest rate, avalanche is clearly superior — you're attacking the most expensive debt first and saving the most interest.

Frequently Asked Questions
What is the debt snowball method?
List all debts smallest to largest by balance (ignore interest rates). Pay minimums on everything, then throw all extra money at the smallest debt. When it's paid off, roll that payment into the next smallest. The 'snowball' grows as each debt is eliminated.
What is the debt avalanche method?
List all debts highest to lowest by interest rate (ignore balances). Pay minimums on everything, then throw all extra money at the highest-rate debt first. This is mathematically optimal — it minimizes total interest paid over the life of the debt.
How much more interest does snowball cost?
It depends on your specific debts. Typically, snowball costs $500-$2,000 more in interest than avalanche on $20,000-$30,000 of debt. The difference decreases if rates are similar across debts. Many people find the motivational benefit worth the small extra cost.
Can I combine both methods?
Yes. Some people use a hybrid: start with snowball to get 1-2 quick wins and build momentum, then switch to avalanche for the remaining larger debts. The most important thing is having a consistent strategy and sticking to it.
