Snowball clears your first debt in 7 mo; avalanche in 7 mo.
First year: snowball 1 cleared · avalanche 1 cleared.
Snowball interest: $1,155
Avalanche interest: $1,155
Difference: $0 (small).
Every time a debt is paid off, its old minimum rolls into the next target. That snowball effect is what makes both methods speed up over time.

- You make every payment on time and don't add new debt.
- Interest accrues monthly at the APR you entered; rates assumed constant.
- Late fees, annual fees, and promo-rate changes are not modeled.
- When a debt is paid off, its minimum rolls into the next target.
This is an estimate for education only — not financial, legal, or tax advice. Your actual payments, interest, fees, and payoff dates depend on your issuer's terms, new charges, and any late or returned payments.
Calculations use simplified assumptions (for example, fixed APRs and no new spending). Real-world results may differ.
Use these numbers as guidance — not as a promise of approval, a specific score change, or a guaranteed payoff date. Always confirm the details with your card agreement or a qualified professional before acting.
This is a planning tool, not a lender statement. If you keep adding new charges, payoff will take longer.
This does not guarantee emotional follow-through — it shows the tradeoffs so you can choose more clearly.
How this calculator works
Enter each balance, APR, and minimum payment. The more accurate your numbers, the more useful the comparison.
Whatever you can pay above the minimums each month gets aimed at one debt at a time — and rolls forward as debts get cleared.
See both payoff orders, both debt-free dates, both total interest costs, and one plain-English recommendation.
Avalanche usually saves more interest because it targets the most expensive debt first. Snowball can still work well because finishing a debt early gives you momentum to keep going — and the best method is often the one you can follow consistently.
