Two popular methods—Debt Snowball and Debt Avalanche—offer different approaches to debt elimination.
In this guide, we'll explore:

- Tools and calculators to track your progress
By the end, you'll know which method will work best for your debt situation and personality.
The Debt Reality Check
Before diving into repayment strategies, let's understand the scope of the problem:
Credit Card Debt Statistics:
- Average American household: $6,194 in credit card debt
- Total US credit card debt: $1.13 trillion
- Average interest rate: 16.43%
Student Loan Statistics:
- Total US student loan debt: $1.77 trillion
- Average borrower: $37,693 in debt
- Default rate: 10.8%
The Problem: Making minimum payments means you'll be in debt for decades and pay thousands in interest.
Debt Snowball Method: Psychology First
How It Works
- List all debts from smallest to largest balance
- Pay minimums on all debts
- Put extra money toward the smallest debt
- Repeat until all debts are paid
Example: Sarah's Debt Snowball
Debts:
- Credit Card A: $500 (15% interest)
- Personal Loan: $2,000 (12% interest)
- Credit Card B: $8,000 (18% interest)
- Student Loan: $25,000 (6% interest)
Monthly Payment: $1,200 Strategy: Pay $1,200 toward Credit Card A first
Psychology Behind Snowball
- Quick wins build momentum
- Visual progress keeps you motivated
- Simplified focus reduces overwhelm
- Behavioral science supports the approach
Research: Studies show people are more likely to stick with debt repayment when they see early progress.
Debt Avalanche Method: Math First
How It Works
- List all debts from highest to lowest interest rate
- Pay minimums on all debts
- Put extra money toward the highest-interest debt
- Repeat until all debts are paid
Example: Sarah's Debt Avalanche
Debts (by interest rate):
- Credit Card B: $8,000 (18% interest) ← Start here
- Credit Card A: $500 (15% interest)
- Personal Loan: $2,000 (12% interest)
- Student Loan: $25,000 (6% interest)
Monthly Payment: $1,200 Strategy: Pay $1,200 toward Credit Card B first
Mathematics Behind Avalanche
- Saves more money in interest
- Faster debt elimination overall
- Mathematically optimal approach
- Better long-term results
Calculation: Paying off 18% debt first saves $1,440 annually vs. paying off 6% debt first.
