Debt Snowball vs Avalanche: Which Pays Off Debt Faster?

The debt snowball and the debt avalanche are two ways to pay off several debts. Both start the same way: pay the minimum on everything, then put every extra dollar toward one debt. The difference is which debt gets the extra money first.

• Debt snowball: pay off the smallest balance first, no matter the interest rate.
• Debt avalanche: pay off the highest interest rate first, no matter the balance.

The avalanche always costs less in interest. The snowball gives you quick wins that help many people keep going. The best method is the one you will stick with until the last debt is gone.

How the debt snowball works

1. List your debts from smallest balance to largest.
2. Pay the minimum on all of them.
3. Put every extra dollar on the smallest one.
4. When it is paid off, take its full payment, the minimum plus the extra, and add it to the next smallest.
5. Repeat. The payment keeps growing as it rolls down the list, like a snowball.

The method was made popular by radio host Dave Ramsey. Its strength is psychological: you see a debt disappear within weeks or months, which builds motivation.

How the debt avalanche works

1. List your debts from highest interest rate to lowest.
2. Pay the minimum on all of them.
3. Put every extra dollar on the one with the highest rate.
4. When it is gone, roll its payment into the next highest rate.
5. Repeat until you are debt-free.

This is the mathematically best order. Every dollar goes where it stops the most interest from piling up.

A real example

Say you have $650 a month to put toward these four debts:

• Store card: $900 at 9.9%, minimum $30
• Card A: $2,500 at 24.9%, minimum $75
• Card B: $6,000 at 21.9%, minimum $180
• Car loan: $9,000 at 7.9%, minimum $220

The minimums add up to $505, so you have $145 extra each month.

With the snowball, you pay the store card off in month 6, Card A in month 16, Card B in month 29, and the car loan in month 35. Total interest: about $4,100.

With the avalanche, Card A goes first and is gone in month 14, then Card B in month 28. The store card and the car loan follow, and you are done in month 35. Total interest: about $3,890.

The avalanche saves about $210 here. You finish in the same month either way, but the snowball gives you your first paid-off debt in month 6 instead of month 14.

The gap grows when your highest-rate debt is also a big one. If Card B were $15,000 at 29%, the avalanche would save much more.

Which method should you choose?

Choose the avalanche if

• You are motivated by numbers and saving the most money.
• Your highest-rate debt is not huge, so you will still see progress.
• The rates on your debts are very different, like 29% on one card and 6% on a student loan.

Choose the snowball if

• You have tried to pay off debt before and lost steam.
• You have several small balances you could clear quickly.
• Your debts have similar rates, so the extra interest cost is small.

Or mix them

Many people knock out one or two tiny balances first for the quick win, then switch to the avalanche for the rest. There is no rule against it.

Ways to speed up either method

• Find more money each month. Even $100 extra makes a real difference. A side income, a lower phone plan or canceling unused subscriptions all count.
• Lower your rates. Call your card issuers and ask. A 0% balance transfer card can pause interest for 12 to 21 months, though there is usually a fee of 3% to 5%.
• Consolidate. A personal loan at a lower rate than your cards can simplify payments, as long as you do not run the cards back up.
• Use windfalls. Tax refunds, bonuses and gifts can wipe out a whole debt at once.
• Stop adding new debt. Switch to debit or cash while you pay down balances.

When rates are high, every month of carried balance costs more. Our guide on handling debt when interest rates are high has more ideas.

Should you pay off debt or invest?

A simple rule: pay off anything above about 7% to 8% first, because few investments reliably beat that. Credit card debt at 20% or more is an emergency. The exception is your employer’s 401(k) match. Contribute enough to get the full match even while paying off debt, because that is an instant 50% or 100% return. See what it is worth in our 401(k) calculator.

Also keep a small emergency fund, even $1,000, before going all in on debt. Without it, the next car repair goes right back on a credit card. Park it in a high yield savings account.

Frequently asked questions

Does the debt snowball hurt my credit score?

No. Paying down balances lowers your credit utilization, which usually raises your score. Keep paid-off credit cards open, unless they have an annual fee, so your available credit stays high.

Should I include my mortgage?

Most people leave the mortgage out and focus on consumer debt first. Mortgage rates are usually lower, and the interest may be tax deductible.

What if two debts have the same rate?

Pay the smaller one first. You get the same interest savings plus a quicker win.

How long will it take me?

It depends on your total debt, rates and extra payment. List your debts, pick a method and track it monthly. Most people with a steady plan clear credit card debt in two to four years.
