How the Debt Avalanche vs Snowball Calculator Works
This calculator compares two of the most popular debt repayment strategies: the debt avalanche method and the debt snowball method.
With the avalanche method, you put all extra payments toward the debt with the highest interest rate. Once it is paid off, you move to the next highest rate. This is the mathematically optimal strategy that minimizes total interest paid.
With the snowball method, popularized by Dave Ramsey, you pay off the smallest balance first. The quick wins build motivation and momentum, making it psychologically easier to stay on track.
Enter your debts above and see the exact dollar difference, time difference, and payoff order for each strategy. Most people save hundreds to thousands of dollars with the avalanche method, but the best plan is the one you actually follow.
Frequently Asked Questions
What is the debt avalanche method?▼
The debt avalanche method prioritizes paying off debts with the highest interest rate first while making minimum payments on all other debts. This approach minimizes total interest paid and is mathematically optimal for saving money. You direct every extra dollar toward the highest-rate debt until it is gone, then roll that payment into the next highest-rate debt.
What is the debt snowball method?▼
The debt snowball method, popularized by Dave Ramsey, prioritizes paying off the smallest balance first. Each time you pay off a debt, you roll that payment into the next smallest debt, creating momentum like a snowball rolling downhill. The quick wins provide psychological motivation to keep going.
Which is better: avalanche or snowball?▼
The avalanche method saves more money on interest and typically pays off debt faster. The snowball method provides quicker psychological wins which can help people stay motivated. Research shows that for many people, the behavioral benefit of the snowball method outweighs the mathematical advantage of the avalanche method. The best method is the one you stick with consistently.
How much money does avalanche save compared to snowball?▼
Savings depend on your specific debts. The wider the spread in interest rates and the more debt you have, the larger the savings. Typical scenarios show savings of a few hundred to several thousand dollars. Use the calculator above with your actual numbers to see your exact savings.
Can I combine both methods?▼
Yes, and many financial advisors recommend it. A common hybrid approach is to first use the snowball method to eliminate one or two small debts for quick wins, then switch to the avalanche method to minimize interest on the remaining larger debts. This gives you both the psychological momentum and the mathematical savings.
What if I can only pay minimums?▼
If you can only afford minimum payments, both methods produce the same result since there is no extra money to direct strategically. In this case, focus on finding ways to increase your income or reduce expenses so you can put even a small extra amount toward debt each month. Even an additional $50 per month can make a significant difference over time.
