Debt Avalanche vs. Snowball: Which Payoff Method Is Better?

If you have balances on more than one credit card, the order in which you pay them off matters. The two most popular strategies are the debt avalanche and the debt snowball. Both work — the best one depends on whether you want to save the most money or stay the most motivated.

How both methods start

The first steps are the same for either method:

1. List every debt with its balance, interest rate (APR), and minimum payment.
2. Decide on a total amount you can put toward debt each month.
3. Pay the minimum on every account so nothing goes delinquent.
4. Send every extra dollar to one "target" debt.
5. When the target is paid off, roll its whole payment into the next target. Your payment grows each time, like a snowball rolling downhill.

The only difference is how you choose the target.

The avalanche method

With the avalanche, you target the debt with the highest interest rate first. Because the most expensive debt disappears first, you pay the least total interest and usually finish sooner. It is the mathematically optimal choice.

The downside: if your highest-rate card also has a large balance, it may be months before you see any debt fully paid off, which can feel discouraging.

The snowball method

With the snowball, you target the smallest balance first, regardless of rate. You pay a bit more interest than with the avalanche, but you get quick wins. Research on consumer behavior suggests those early successes help many people stick with their plan.

Example

Imagine two cards and a $400 monthly debt budget:

• Card A: $1,000 balance at 18% APR, $35 minimum
• Card B: $4,000 balance at 24% APR, $100 minimum

Snowball targets Card A. After paying Card B's $100 minimum, $300 a month goes to Card A, which is gone in about four months. Then the full $400 goes to Card B.

Avalanche targets Card B because its 24% rate is higher. Card A gets only its minimum until Card B is paid off. This saves interest overall, but your first paid-off card comes much later.

Which one should you choose?

• Choose avalanche if your interest rates differ a lot, you are motivated by numbers, or your balances are similar in size.
• Choose snowball if you have several small balances, you have struggled to stay on a plan before, or you want fewer bills to track quickly.

The difference in interest is often smaller than people expect. The biggest factor is consistency: picking a plan and paying more than the minimum every month.

Tips to speed things up

• Stop using the cards while you pay them down.
• Call your issuer and ask for a lower APR.
• Look at 0% balance transfer offers, and watch the transfer fee.
• Put windfalls like tax refunds or bonuses toward your target debt.
• Find extra room in your spending with a monthly budget.
