Snowball vs Avalanche: 3 Real Examples
May 26, 2026 · 6 min read
Theory is fine, but numbers tell the real story. I ran three common debt scenarios through both methods. Here's what happened.
Example 1: Typical Credit Card Debt
Debts: $800 (18%), $2,500 (24%), $4,200 (29%)
Extra per month: $250
Snowball: 28 months, $2,980 interest
Avalanche: 26 months, $2,640 interest
Avalanche saves: $340, 2 months
Small difference. If snowball keeps you motivated, it's worth the $340.
Example 2: One High-Rate Card + Two Low-Rate Loans
Debts: $1,500 (8% car loan), $3,000 (10% personal loan), $6,000 (28% credit card)
Extra per month: $400
Snowball: 22 months, $1,820 interest
Avalanche: 17 months, $1,090 interest
Avalanche saves: $730, 5 months
Big gap. The 28% card is bleeding money while snowball focuses on the smaller 8% loan. Here, avalanche is clearly the right call — and you should still use avalanche even if you prefer snowball, because $730 is real money.
Example 3: Similar APRs, Very Different Balances
Debts: $600 (20%), $5,000 (21%), $12,000 (22%)
Extra per month: $500
Snowball: 34 months, $5,100 interest
Avalanche: 33 months, $4,950 interest
Avalanche saves: $150, 1 month
Almost identical. When APRs are close, the method barely matters. Pick whatever you'll stick with.
The Pattern
- If your highest-rate debt is also your largest balance: avalanche wins big.
- If your debts have similar APRs: the difference is negligible.
- If your smallest debt has a high APR: they converge — both methods attack it early.
