Debt Snowball Vs. Debt Avalanche: Which Payoff Method Works Best?

If you're juggling multiple debts, figuring out which one to pay off first can feel overwhelming. Should you tackle your smallest balance to build momentum, or focus on the debt costing you the most in interest?

The debt snowball and debt avalanche are two debt payoff methods for organizing your repayment strategy. Both involve making minimum payments on all your debts while directing extra money toward one account at a time. The difference is which debt gets your extra payments.

The debt snowball prioritizes quick wins, while the debt avalanche prioritizes savings in interest. The best method for you depends on your financial situation, what motivates you, and how consistently you can follow your plan.

What is the debt snowball method?

The debt snowball method focuses on paying off your smallest debt balance first, regardless of its interest rate.

Here's how it works:

1. List your debts from smallest to largest balance. Include each account's interest rate, required minimum, and due date so you can plan payments.
2. Make the minimum payment on every debt.
3. Put any extra money available for debt repayment toward the smallest balance.
4. Once that debt is paid off, roll the money you were paying toward it into the next-smallest debt.
5. Repeat until all your debts are paid off.

Example of the debt snowball method

Imagine you have the following debts, using hypothetical balances and interest rates:

With the snowball method, you'd prioritize your debts in this order:

1. Chase 2: $565
2. Discover: $741
3. Chase 1: $2,391
4. Citibank: $4,122
5. Bank of America: $10,212

You'd continue making minimum payments on every account while putting your extra repayment money toward Chase 2. After paying it off, you'd direct that payment toward Discover, then Chase 1, and so on.

For example, assume Chase 2's required minimum is $25 and you can afford $100 extra each month. You would pay $125 toward Chase 2 while covering the other minimums, then add that $125 to Discover's required payment once Chase 2 is paid off.

Pros and cons of the debt snowball method

Pros

• Quick wins: Paying off a smaller balance can give you a sense of accomplishment early in the process.
• Motivation: Seeing individual debts disappear can help you stay committed to your plan.
• Fewer payments to manage: As accounts are paid off, you'll have fewer monthly payments to keep track of.
• Added flexibility: Clearing away the smaller balance debts creates financial flexibility in the event that your income is disrupted or you're stuck with an unexpected expense.

Cons

• Potentially higher interest costs: You may pay more interest over time if you leave high-interest debts for later.
• Not always the cheapest option: A small balance with a low interest rate may take priority over a much more expensive debt.

The snowball method can be a good fit if you're feeling overwhelmed by multiple balances or believe that early progress will help you stay motivated.

What is the debt avalanche method?

The debt avalanche method prioritizes the debt with the highest interest rate, regardless of its balance.

Here's how it works:

1. List your debts from highest to lowest interest rate. Check your latest statements if you not sure about the interest rate on your accounts.
2. Make the minimum payment on every debt.
3. Put any extra repayment money toward the debt with the highest interest rate.
4. Once that debt is paid off, add its full payment to what you pay toward the debt with the next-highest interest rate.
5. Continue until all your debts are paid off.

Example of the debt avalanche method

Using the same five debts as above, you'd prioritize them in this order:

1. Discover: 27.66%
2. Chase 2: 23%
3. Citibank: 15.5%
4. Chase 1: 12%
5. Bank of America: 9.9%

You'd make minimum payments on all five accounts and direct your extra money toward Discover first. After paying it off, you'd move to Chase 2, then Citibank, and continue down the list.

Pros and cons of the debt avalanche method

Pros

• Potential interest savings: Paying down high-interest debt first generally reduces the amount of interest you pay over time when comparing the same debts and monthly payment budget.
• Cost efficiency: More of your money can go toward eliminating the most expensive debt first.
• A clear repayment strategy: Ranking debts by interest rate gives you a straightforward way to prioritize extra payments.

Cons

• Fewer early wins: If your highest-interest debt has a large balance, it may take a while to pay it off.
• Motivation can be harder to maintain: You might not see an account disappear for some time, even when you're making consistent progress.

The avalanche method is often a good fit if saving money on interest is your primary goal, and you can stay motivated while working toward longer-term milestones. Track your total balance and interest charges each month, even before an account reaches zero.

Debt snowball vs. debt avalanche: What's the difference?

To see the tradeoff, compare both methods using the same five debts and a $600 monthly payment budget (note: all numbers are an estimate).

In this example, snowball delivers an earlier first payoff, while avalanche saves about $87 in interest. Both methods require the same number of monthly payments.

Both methods work best when you keep your total monthly debt payment steady as balances fall and avoid adding new debt. The right choice is the one that helps you make consistent progress toward becoming debt-free.

How to choose the best debt payoff strategy for you

If you're unsure which approach to use, start by considering your financial priorities and what will help you stick with a plan.

Choose the snowball method if you need motivation

If you're juggling several balances and feel discouraged by how much you owe, eliminating a smaller debt can provide a tangible milestone. That progress may make it easier to maintain your repayment habits.

Choose the avalanche method if you want to save on interest

If you're comfortable with a longer wait before paying off an individual account, focusing on your highest-interest debt can help reduce your overall borrowing costs.

Consider combining the two

You don't have to follow either method rigidly. For example, you could pay off one or two small balances to build momentum, then switch to the avalanche method to prioritize high-interest debt. This approach gives you an early win while still focusing on interest savings over time.

Whichever method you choose, consistency matters more than finding a perfect formula. If an unexpected expense forces you to adjust your plan temporarily, revisit your budget and return to your repayment strategy when you're able.

How to combine your debt payoff strategy with a budget

Both methods depend on paying more than the minimum whenever possible. Before choosing how much extra to put toward debt, you need to understand what your budget can realistically support.

Start by reviewing your income and expenses. Treat minimum debt payments as required expenses, then look at what's left after covering necessities and other financial obligations. MMI's guide to the three major types of expenses can help you identify where your money goes and where you may have room to adjust.

Next, determine how much extra you can consistently afford to put toward debt each month. If debt repayment is a priority, consider whether you can temporarily reduce discretionary spending, such as dining out, entertainment, or nonessential purchases.

It's important to choose an amount you can sustain. Committing too much to debt repayment could leave you without enough cash to cover an unexpected expense, potentially forcing you to borrow again. Consider setting aside some emergency savings alongside debt payments so a surprise bill is less likely to derail your plan.

Could lowering your interest rates help you pay off debt faster?

Your repayment strategy matters, but so does the cost of your debt. When interest rates are high, a significant portion of your payments may go toward interest instead of reducing your principal balance.

Lowering your interest rates can help more of your money go toward paying down what you owe. This can make debt repayment more affordable and help you make progress faster.

One option to explore is a debt management plan (DMP) through a nonprofit credit counseling agency. With a DMP, a credit counselor works with your creditors to seek lower interest rates and more manageable repayment terms. You typically make one monthly payment to the agency, which distributes payments to your participating creditors. A DMP is not a loan, and you repay the debts included in the plan in full.

Lower interest rates can complement either the snowball or avalanche method. If you qualify for a DMP, a credit counselor can help you understand how it may affect your repayment plan and monthly budget.

MMI offers free financial counseling, available online and over the phone 24/7. Whether you need help building a budget, comparing repayment strategies, or exploring a debt management plan, a counselor can help you identify practical next steps.
