Debt Snowball vs Avalanche: Which Is Better? Real Numbers

You have a few debts. A credit card, maybe a car loan, maybe a personal loan. Every month you pay all of them a little, and every month the total barely moves. It feels like running on a treadmill.

The way off the treadmill is to stop spreading your money evenly and pick one debt to attack. Two famous plans tell you which one to pick: the debt snowball and the debt avalanche. They are almost the same plan with one small difference, and that difference changes both how much you pay and how it feels along the way.

The quick answer

• Snowball: pay off the smallest balance first. You get quick wins and keep going.
• Avalanche: pay off the highest interest rate first. You pay the least interest, and you finish a bit sooner.
• Avalanche wins on math. Snowball wins when you need motivation. In our example below, the gap was only about $330.
• The best plan is the one you will stick with until the last payment.

The ground rules (the same for both plans)

1. List every debt with its balance, interest rate (APR) and minimum payment.
2. Pay the minimum on all of them every month, no exceptions. A missed payment brings fees and damages your credit.
3. Find an extra amount to put on one target debt. Even $50 counts.
4. When the target is paid off, take its whole payment (minimum plus extra) and add it to the next target. The payment grows like a snowball rolling downhill.

How the debt snowball works

Sort your debts from the smallest balance to the largest. Ignore interest rates. Put all extra money on the smallest one. When it is gone, move to the next smallest.

The strength of this method is the feeling. Each time a debt disappears, you get a win. You have one less bill to track, and one less reason to feel stressed. The personal finance author Dave Ramsey made this plan famous under the name "debt snowball", for exactly that reason.

How the debt avalanche works

Sort your debts from the highest interest rate to the lowest. Ignore the balances. Put all extra money on the highest-rate debt. When it is gone, move to the next highest.

The strength here is math. The debt that grows fastest gets killed first, so less interest piles up. When you keep paying the same total every month, this is the plan that costs the least interest.

Side by side: a real example

Imagine you have these three debts and $200 a month extra on top of the minimums. That is a total of $700 a month.

Avalanche saves about $330 and one month. That is real money, but not huge. Notice something else: snowball gave the first "win" after 11 months, and avalanche took 17. That is a six-month wait with nothing to celebrate, and it is exactly why some people quit.

You can plug in your own debts in our debt payoff calculator, which runs both plans and shows the difference.

When the difference is big, and when it is tiny

The size of the gap depends on how your debts are shaped.

• Big gap: you have one large balance at a very high rate. Say a $9,000 credit card at 26% (minimum $270), plus a $900 store card at 12% (minimum $35) and a $1,500 medical bill at 0% (minimum $50), with $300 a month extra. Snowball costs about $2,800 in interest and takes 22 months. Avalanche costs about $2,260 and takes 21 months. That is more than $500, because in the snowball the big expensive card gets only its minimum payment for the first seven months.
• Tiny gap: your rates are all close to each other. With three cards at 19%, 20% and 21% (balances of $2,000, $3,000 and $4,000, and $200 a month extra), the two plans differ by less than $60 in interest. Pick the one that motivates you, and do not worry.

What does the research say?

Researchers have studied how people actually behave. A 2012 study in the Journal of Marketing Research by David Gal and Blake McShane looked at the multi-year records of almost 6,000 people in a debt settlement program. People who paid off several balances early were more likely to become debt-free in the end, regardless of the amount of debt or the interest costs. The small wins mattered.

A 2016 study in the Journal of Consumer Research by Keri Kettle and colleagues, which combined a field study with three experiments, found that putting repayments on fewer accounts raised people's motivation to get out of debt, and that the effect was strongest when the payments went to the smallest account. Motivation is not the same as saving money, so the choice is yours. In short: the snowball works because people stay with it, and the avalanche works because the math is better. Both beat doing nothing.

How to choose

• Choose avalanche if you are organized, you are driven by numbers, and you have one very high-rate debt.
• Choose snowball if you have given up on plans before, or you have many small bills that cause stress.
• Try a hybrid if you are not sure. Knock out one or two tiny debts first for the quick wins, then switch to avalanche for the rest.

How to pay off credit card debt faster

Whichever plan you choose, these moves help it go faster.

• Stop adding new debt. Put the cards away. New charges undo your progress.
• Build a small cushion. Even $500 to $1,000 in savings keeps a surprise car repair off the card. Our guide to building an emergency fund on any income shows how to do it when money is tight.
• Find the extra money. Review spending, sell things you do not use, and apply tax refunds or bonuses.
• Call your card company. Ask for a lower rate or a hardship plan. It costs nothing to ask.
• Consider a 0% balance transfer. If you can pay the balance off before the promotional period ends and the transfer fee is small, you save interest. If you cannot, the rate jumps back up.
• Consider a consolidation loan. One loan at a lower rate can replace several cards. It helps only if you stop using the cards.

Be careful with companies that promise to "erase" your debt for a fee. If you feel stuck, a nonprofit credit counselor can help with a debt management plan. The Federal Trade Commission explains how to spot debt relief scams in its consumer alert Looking for debt relief? Here's how to avoid a scam.

Where do mortgage and student loans fit?

Mortgages and federal student loans usually have lower rates and extra protections, so they go last in an avalanche. Get high-rate consumer debt under control first. After that, you can decide whether to send extra money to the mortgage (read how to pay off your mortgage early) or to your student loans.

Frequently asked questions

Does the debt snowball really work?

Yes, because it keeps people going. It costs a little more in interest than the avalanche, but a plan you finish beats a perfect plan you abandon.

Is the debt snowball or avalanche faster?

The avalanche is usually a little faster to become fully debt-free, and costs less in interest, or the same. The snowball is faster to clear the first debt.

Should I save money or pay off debt first?

Do both in order. Save a small starter fund (for example $500 to $1,000) so a surprise does not go on a card. Then attack high-rate debt. Build the bigger emergency fund after the expensive debt is gone.

Is a debt consolidation loan better than the snowball?

It can be, if the new rate is clearly lower than your current rates and you stop spending on the old cards. It does not replace a payoff plan. You can use a snowball or avalanche on the consolidated loan, plus any other debts.

Will paying off debt help my credit score?

Paying down credit card balances usually helps, because it lowers your credit utilization. Closing an old account right after paying it off can lower your score a little, so keep old cards open if they have no annual fee.

How do I pay off credit card debt fast with a low income?

Start by listing every debt, stop new charges, and add even a small extra amount to one target. Ask for a lower rate, apply every windfall to the target, and use a nonprofit credit counselor if the minimums feel impossible.

The bottom line

The avalanche wins on paper. The snowball wins on momentum. In many real lives the gap is a few hundred dollars, which is far smaller than the cost of waiting another year to start. Pick one this week, automate the payments, and mark your first payoff date on the calendar.
