The debt snowball and debt avalanche are the two dominant structured repayment strategies. Both keep minimum payments on all accounts while directing every extra dollar to one debt at a time. Once that debt is eliminated, its full payment amount rolls into the next target. The only difference is the order of attack.
Snowball ranks debts by smallest balance first for quick psychological wins. Avalanche targets highest interest rates first to minimize total interest paid. When it comes to pure savings, avalanche wins decisively in nearly every scenario.
Here is a realistic $33,000 debt example that reflects many households:
- Car Loan: $3,000 at 8% APR, minimum $100
- Credit Card B: $4,000 at 24% APR, minimum $120
- Credit Card C: $8,000 at 18% APR, minimum $200
- Student Loan: $18,000 at 7% APR, minimum $250
Total minimums: $670/month. Extra cash available: $800/month. Total monthly budget: $1,470. Interest compounds monthly.
Avalanche Results (Highest Rate First)
Order: 24% card → 18% card → 8% car → 7% student loan
- Months to debt-free: 32
- Total interest paid: $3,922
- Total paid: $36,922
Snowball Results (Smallest Balance First)
Order: $3k car → $4k card → $8k card → $18k student loan
- Months to debt-free: 33
- Total interest paid: $4,504
- Total paid: $37,504
Direct Comparison
| Metric | Avalanche | Snowball | Avalanche Wins By |
|-------------------------|---------------|---------------|-----------------------|
| Time to Zero | 32 months | 33 months | 1 month faster |
| Interest Paid | $3,922 | $4,504 | $582 saved |
| Total Money Spent | $36,922 | $37,504 | $582 saved |
Avalanche saves $582 and finishes one month earlier. While the dollar amount seems modest here, the gap grows dramatically with larger balances or higher rates. On $100,000+ debt portfolios, thousands of dollars separate the two strategies.
