Debt avalanche vs snowball comes down to cost against quick wins. The avalanche sends your extra money to the debt with the highest interest rate, and it usually costs less. The snowball sends it to the smallest balance, so your first debt disappears sooner. On the example debts in our payoff planner, with $441 a month, the avalanche finished in 33 months with $3,754.85 of interest. The snowball took 34 months and $4,182.17.

Choosing an order is one piece of a bigger plan for how to get out of credit card debt.

How the avalanche and snowball methods work

Both start the same way. List every debt with its balance, its APR (the yearly interest rate) and its minimum payment. Pay every minimum, every month. Whatever else you can put toward debt is your extra payment, and it goes to one debt at a time. The two methods differ only in which debt gets it.

Debt avalanche: highest rate first

The extra goes to the debt with the highest APR, then the next-highest. The Consumer Financial Protection Bureau (CFPB) calls this the highest interest rate method and says to pay that debt off as quickly as possible "because it's costing you the most" (CFPB: How to reduce your debt).

Debt snowball: smallest balance first

The extra goes to the smallest balance, whatever its rate. In the CFPB's words, "You keep on making the minimum payments on all of your debts, and you put any extra funds you have toward paying off the smallest debt."

The rollover

When a debt is paid off, keep its payment working. The CFPB's reducing debt worksheet says to allocate "the entire payment (monthly payment + extra payment)" you were making to the next debt on the list (CFPB: Your Money, Your Goals reducing debt worksheet). That's why either plan speeds up over time.

Why the avalanche usually costs less

Interest is charged on what you still owe. A dollar that comes off a 29% balance stops growing at 29%. The same dollar sent to a 0% bill saves no interest. The CFPB worksheet lists the avalanche's advantage as "In the long-run, this method can save you money," and the snowball's drawback as "You may pay more in total because you are not necessarily eliminating your most costly debt first."

When the difference is small

The order matters only when the two methods pick different targets. Here are the same example debts under a few scenarios, run with the planner's math:

When the smallest balance also carries the highest rate, as with Card B once the hospital bill is gone, both methods pick the same debt and match to the cent. With minimums only, the example also came out even: the hospital bill closes on its own $60 minimum, and both orders then send that freed $60 to Card B. Rates that sit close together shrink the gap too, since each dollar saves about the same interest wherever it goes.

The size of the extra payment mattered far more than the order. Going from $100 to $300 extra cut 13 months and $1,657.15 of interest under the avalanche, nearly four times the gap between the methods.

When the snowball can still be the better choice

The avalanche wins on paper, but you have to live with the plan for years. If your highest-rate debt is also large, the avalanche can run a long time before any account reaches zero. The CFPB worksheet names that downside: "You may not feel like you are making progress very quickly, especially if this debt is large." For the snowball it says: "You may see progress quickly, especially if you have many small debts. For some people, this creates momentum and motivation."

That counts most when you have several small balances you could clear within months, or when you've started a payoff plan before and stopped. Run your debts both ways. If the snowball costs a little more and you'll stick with it, that's a fair price. If the gap runs into the thousands, give the avalanche a harder look.

Worked example: the planner's sample debts

These are the debts the payoff planner loads when you click "Try an example."

The minimums add up to $341, so $100 extra makes a $441 monthly budget. Each month the planner adds interest (the APR divided by 12), pays every minimum, sends the rest to the target debt, and rolls each paid-off minimum into the next target. It holds minimums fixed and assumes no new charges or fees, so treat the results as estimates.

The avalanche order is Card B, then Card A, then the hospital bill. The snowball order is the hospital bill, then Card B, then Card A.

The snowball clears the hospital bill nine months before the avalanche closes anything. That early win costs $427.32 more interest and one extra month, because Card B's 29.24% balance keeps growing while the extra money goes to a bill that charges no interest.

One card, several rates: how issuers apply extra payments

A single credit card can carry more than one APR, such as a purchase rate and a higher cash advance rate. A federal rule decides how your payment splits across them.

Under Regulation Z, 12 CFR 1026.53, when you pay more than the minimum on a credit card account, the issuer "must allocate the excess amount first to the balance with the highest annual percentage rate" and any remaining portion to the other balances in descending order of rate (CFPB: Regulation Z § 1026.53). The CFPB's official interpretation gives an example: with a $500 cash advance balance at 20% and a $1,500 purchase balance at 15%, a payment of $800 above the minimum puts $500 on the cash advance and the remaining $300 on purchases.

The rule covers only the amount above the minimum. It doesn't address how the issuer applies the minimum payment itself. Deferred interest promotions get an exception: in the two billing cycles right before the promotion ends, the excess goes first to the deferred interest balance. So inside each card, your extra payment already follows avalanche order. Your decision is which card gets it.

Both methods fail if you keep charging

Neither order can outrun new spending. The planner assumes your balances only go down. Send $100 extra to Card B and put $100 of new purchases on it the same month, and that card's balance hasn't moved. Before you start, take the cards out of your wallet and remove them from saved payment settings. If you later join a debt management plan, the FTC notes you might have to agree not to apply for or use any more credit until the plan is finished (FTC: How to get out of debt).

When neither method works

If the planner shows your debts never reaching zero, your total balance isn't shrinking at the budget you have, and no order can change that. That's the point to talk to a nonprofit credit counselor.

The CFPB says credit counseling organizations are usually nonprofits whose counselors are certified and trained in consumer credit, money and debt management, and budgeting, and that working with one can be a way to get free or low-cost advice (CFPB: What is credit counseling?). A counselor may review your budget and help you decide which debts to pay first (CFPB: Planning to become debt-free?).

Under a debt management plan, you make one payment to the counseling organization each month or pay period, and it pays your creditors. The same CFPB handout says counselors usually don't try to reduce what you owe, but they may lower your payments by spreading them over a longer period or get your creditors to lower your interest rate. The FTC adds that a successful plan can take 48 months or more to complete.

Debt settlement pros and cons covers the costs and risks of settling instead.

Bottom line

If your numbers show a real interest gap, the avalanche saves money. If the gap is small, or early wins are what will keep you paying, the snowball is a fair choice. Either way, pay every minimum, keep new charges off the cards, and check that your total balance falls each month. If it doesn't, call a nonprofit credit counselor.

Common questions

Which is better, the debt avalanche or the debt snowball?

The avalanche usually costs less interest because your extra money goes to the highest-rate debt first. The snowball closes small balances sooner. On our example debts the avalanche saved $427.32 and one month, so compare both on your own numbers and pick the one you will stick with.

Does the debt snowball cost more than the avalanche?

It can. The CFPB notes you may pay more in total with the snowball because you are not necessarily paying off your most costly debt first. If your smallest balance also has the highest rate, the two methods are the same plan and cost the same.

How does a credit card company apply a payment above the minimum?

Under Regulation Z (12 CFR 1026.53), when one card has balances at different rates, the issuer must apply the amount above the minimum to the highest-rate balance first, then to the others in order of rate. There is an exception in the last two billing cycles before a deferred interest promotion ends.

What if neither method pays off my debt?

If your total balance does not go down at the budget you have, the order will not fix it. A nonprofit credit counselor can review your budget and may set up a debt management plan, which the FTC says can take 48 months or more to complete.
