How the Debt Snowball Method Works
The debt snowball method, popularized by Dave Ramsey, uses psychological momentum to help you pay off debt faster.
- List all debts from smallest balance to largest
- Make minimum payments on every debt
- Throw all extra money at the smallest balance
- When that debt is paid off, roll its entire payment into the next smallest
- Repeat until all debts are paid off
As each debt is eliminated, the amount you can put toward the next debt grows like a snowball rolling downhill. The quick wins from paying off small debts keep you motivated throughout the journey.
Example: With debts of $500, $2,000, and $8,000 — you attack the $500 first. Once it is gone, that payment plus extra goes to the $2,000 debt, and so on.
Tips & Considerations
- Double-check your name before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both total interest paid and payoff date — they work together to give you the full picture.
- Bookmark this page for quick access next time you need to manage your finances.
- If you're unsure about your extra monthly payment, start with a conservative estimate and adjust from there.
Frequently Asked Questions
What is the debt snowball method?
The debt snowball method pays off debts from smallest balance to largest, regardless of interest rate. You make minimum payments on all debts and put any extra money toward the smallest balance. When that debt is paid off, you roll its entire payment into the next smallest debt, creating a snowball effect that grows as each debt is eliminated.
How does debt snowball compare to debt avalanche?
The snowball method targets smallest balances first for quick psychological wins. The avalanche method targets highest interest rates first and saves more money overall. The snowball method typically costs slightly more in interest but has higher success rates because the quick wins keep people motivated to stay on track.
How much extra should I pay toward debt?
Any extra amount helps significantly. Even an extra $50 to $100 per month can cut years off your payoff timeline. The key is consistency. Look for ways to free up money by cutting subscriptions, selling items, or picking up extra work. Every extra dollar goes directly to paying down principal on your target debt.
Should I use the debt snowball if I have high-interest debt?
If your highest-interest debt also has the largest balance, the avalanche method will save you significantly more money. However, if you struggle with motivation or have tried other methods without success, the snowball method's quick wins can keep you on track. The best debt payoff method is the one you actually stick with.
Does the debt snowball method work?
Research from Harvard Business Review confirms that the debt snowball method has higher completion rates than mathematically optimal approaches. The quick wins from paying off small debts create positive reinforcement that keeps people motivated through the entire debt payoff journey.
Should I include my mortgage in the debt snowball?
Most financial experts recommend excluding your mortgage from the debt snowball. Focus on consumer debt first — credit cards, personal loans, car loans, and student loans. Once all consumer debt is paid off, you can decide whether to aggressively pay down your mortgage or invest the extra money instead.
