Avalanche vs Snowball: Fastest Way to Pay Off Credit Cards

A month-by-month comparison of the debt avalanche and debt snowball on three real-world card balances, how much each saves over minimum payments, and how to choose.
If you have balances on several credit cards, the order you pay them off in changes how long it takes and how much interest you pay. The two best-known strategies are the debt avalanche and the debt snowball. Both beat paying only the minimums by a huge margin — but they win in different ways, and the right one depends on what keeps you going.
The two strategies
- Debt avalanche: pay the minimum on every card, then put every extra dollar toward the card with the highest interest rate. When it's gone, move to the next-highest rate.
- Debt snowball: pay the minimum on every card, then put every extra dollar toward the card with the smallest balance. When it's gone, roll its payment into the next-smallest.
A worked example
Take three cards totalling $6,300, with $500 a month available for debt payments. To keep the comparison clear, each card's minimum payment is held fixed:
| Card | Balance | APR | Minimum payment |
|---|---|---|---|
| Card A | $1,500 | 19.99% | $40 |
| Card B | $4,000 | 26.99% | $100 |
| Card C | $800 | 22.99% | $25 |
Here is how each approach plays out, month by month:
| Strategy | Debt-free in | Total interest | First card paid off |
|---|---|---|---|
| Minimum payments only ($165/month) | 104 months | $7,661 | — |
| Snowball ($500/month) | 15 months | $1,132 | Month 3 (Card C) |
| Avalanche ($500/month) | 15 months | $1,021 | Month 11 (Card B) |
The biggest win isn't the choice of strategy — it's paying more than the minimum. Raising the payment from $165 to $500 a month cuts the time from more than eight years to just over one, and saves over $6,500 in interest. Between the two strategies, the avalanche saves another $111 here because the largest balance also has the highest rate.
Which one should you choose?
- Choose the avalanche if you're motivated by the numbers. It always costs the same or less in interest, and the gap grows when your highest-rate card also has a big balance.
- Choose the snowball if quick wins keep you on track. Clearing a whole card in the third month is a powerful motivator, and a plan you stick with beats a better plan you abandon.
- Mix them if two cards have similar rates: clear the smaller of the two first for an early win, then switch to the avalanche.
Making either plan work
- Keep the total payment fixed. When a card is paid off, its payment moves to the next card instead of back into your spending.
- Stop adding new charges. New purchases on the cards you're paying down undo the progress.
- Ask for a lower rate. A call to your card issuer can sometimes cut the APR, which helps either strategy.
- Consider a 0% balance transfer carefully. It can save a lot if you clear the balance before the promotional rate ends, but transfer fees of around 3%–5% apply and the rate jumps afterwards.
