Avalanche vs Snowball: How to Pay Off Debt Faster

You've got more than one debt and a bit of money left over after your minimums, and you're trying to work out which debt gets it. With avalanche you pay down the highest interest rate first. With snowball you pay off the smallest balance first. Avalanche costs you less and gets you to zero sooner. Snowball clears your first debt far earlier, and that's why plenty of people pick it knowing it costs more. If your rates all sit close together, it doesn't matter much which one you pick.

Key takeaways

• Avalanche puts your spare money on the highest interest rate. It never costs you more than snowball, and on most sets of debts it costs you less.
• Snowball puts it on your smallest balance. You clear a whole debt much sooner, and a lot of people keep going because of it.
• Everything else is identical. You pay every minimum, you put the extra on one debt, and when that debt's gone, everything you were paying on it moves to the next one.
• Neither one does anything for you until you've got money left after the minimums. Free up another $50 a month and it helps you whichever way you go.

What both methods share

Almost everything. You keep every debt current, you send every minimum on time, and you put whatever's left on one debt until you've cleared it. Then you take everything you were paying on that one, minimum and extra together, and move it onto the next debt. Your total payment never drops, so each debt goes down faster than the last one did. They differ on exactly one thing, and that's which debt you start with.

Before either name means anything to you, you need your own numbers written down. Go through each debt and pull three things off it.

1. The balance. What you still owe today, not what you originally borrowed.
2. The interest rate. The one printed on your current statement, not whatever you were quoted when you signed up.
3. The minimum payment. What you've got to send every month to keep the account in good standing.

Your credit cards, your lines of credit, the car loan, any buy-now-pay-later plan, anything you owe that carries a balance and a rate. You'll find all three numbers on your statement or in your banking app, and it takes about five minutes.

What if there's nothing left after the minimums?

Neither one helps you yet, because you need money left after every minimum is paid before either does anything. With nothing left over, you'd get an identical result from avalanche and snowball.

You've got two ways to make room. You can cut what's going out, even for a few months, and send whatever you free up to one debt.¹ Or you can talk to the people you owe and try to work out different terms, which is a normal part of managing debt.¹

If your expenses run past your income most months, you've got a bigger job than choosing between them, and that one comes first. Start with seeing where your money goes. Even $50 a month gives you something to work with.

How much does the order save you?

Your answer depends on how far apart your interest rates sit. On three illustrative debts where the smallest one isn't the most expensive one, starting with the highest rate saves you $1,288 and gets you finished two months sooner.

Say those three are yours, and you've got $350 to put toward them every two weeks. That's about $758 a month, because 26 paydays a year works out to a bit more than two a month. Your minimums come to $570, which leaves you about $188 to put on one debt.

Send it to the card, and you'll be debt-free in 32 months, having paid $4,490 in interest. Start with the line of credit instead, and you'll finish in 34 months, having paid $5,778. Same debts, same money going in, and $1,288 between them.

You get charged interest every month on what you still owe, at each debt's own rate. A dollar sitting on the 23.9% card costs you more than three times what the same dollar costs you on the 6.9% car loan. Bring the card down first and less of every payment you make disappears into interest.

Why do people pick the snowball anyway?

With avalanche you don't fully clear anything until month 28, and with snowball your line of credit is gone at month 11. That's 17 months longer to go without a single debt coming off your list, and plenty of people already know that about themselves.

With avalanche you spend more than two years putting everything spare on an $11,000 card. Your balance goes down every month of it, and you save real interest every month of it. You just don't get to cross anything off.

That shows up in how people run these plans. Hardly anyone keeps an all-or-nothing push going for long. The ones who reach the end tend to keep a small amount heading toward something they want, a holiday or a laptop, while the bulk of it goes on the debt. They stay with it because they can watch two things move instead of one.

Some people split the difference. They clear one small balance first, then switch to the highest rate for everything left, so they give up part of the interest saving and buy an early payoff with it. Either way you're signing up for 32 or 34 months, and most people find the stretch harder than the choice.

When the order barely matters

What the choice is worth to you depends on what you're carrying.

• Your rates sit close together. That $1,288 comes from a wide gap, 23.9% against 6.9%. If everything you owe is within a few points, your saving shrinks toward nothing and either way is fine.
• Your smallest debt is also your most expensive. Then you'd start on the same debt either way, and you've got no decision to make.
• You're in Quebec. Card minimums there are 5% of your balance, rather than a flat amount plus interest or roughly 3%.² Bigger minimums leave you less to send anywhere, so the choice is worth less to you.
• Your minimums are large for some other reason. Your credit agreement says how your card sets its minimum, and it's usually a flat amount near $10 plus interest and fees, or about 3% of what you owe.² The more of your payment the minimums take, the less the choice changes for you.
• You can find more money. Take a $2,000 card at 18% on its own. Pay only the $60 minimum and you're at it for three years and eleven months, paying $793 in interest. Add $100 a month and you're clear in one year and two months, for $231.²

You settle this with the real rate on each of your debts, and nobody's going to hand you those numbers from outside. They move with your lender and with what you signed. Check your most recent statement rather than what you remember being quoted.

What most people land on

Most people carrying one expensive card alongside a couple of cheaper loans land on avalanche, because they're paying nearly all of their interest on that one card. Most people carrying four or five smaller balances land on snowball, because clearing two of them inside a year makes the rest feel reachable. People who've walked away from a repayment plan before tend to choose whichever one shows them something soonest, even when they can see the price of it.

Write your own balances and rates down side by side and you'll usually see which of those you are within a minute.

Run your own numbers

Your debts aren't these three, and your gap could be a lot bigger or a lot smaller than $1,288. Run your own numbers with your own balances, rates and minimums. It'll play both orders out month by month, show you when each of your debts clears, and put a dollar figure on what the choice is worth to you, on whatever pay schedule you're on.

Common questions

Does paying off debt this way help or hurt my credit score?+

Neither one changes it. Both keep every minimum paid on every debt, every month. Missing a payment or letting an account sit past due hurts you, and that is true whichever way you go.

Should I keep saving while I'm paying off debt?+

Most people do better keeping a small buffer than sending every last dollar to the debt. With nothing set aside, one car repair goes straight back onto the card and undoes months of work. A common approach is to build about a month of essentials first, then turn to the debt.

Should I pay off my car loan or my credit card first?+

Go by rate if cost is what you care about. Pull both statements and compare the two numbers, and whichever is higher goes first under avalanche. Under snowball you compare the balances instead, and the car loan is often the bigger of the two.

Is a consolidation loan better than either method?+

Consolidation swaps several debts for one, ideally at a lower rate. It changes what you owe rather than the order you pay it in, so it answers a different question. It can help, and the cards it clears can fill back up again, which is how some people end up with the loan and new balances both.
