Debt Snowball vs Debt Avalanche: Which Is Best?

If you are looking for a way to pay off your balances, you might be considering two of the most popular strategies: the debt snowball and the debt avalanche. Both methods could help you eliminate what you owe, but they approach the process from different angles. One strategy focuses on small psychological victories to keep you motivated, while the other focuses on mathematical efficiency to minimize the amount of interest you pay. Understanding how these strategies function may help you make an informed decision that aligns with your personal habits and monthly budget.

Understanding the Debt Snowball Method

The debt snowball method prioritizes your balances by size, starting with the smallest amount and working your way up to the largest. Under this strategy, you make the minimum required payment on all of your debts except for the smallest one. You allocate any extra money from your monthly budget toward that smallest balance until it is completely paid off.

Once the smallest balance is eliminated, you take the entire amount you were paying toward it and apply it to the next-smallest balance. This process continues, creating a "snowball" effect where your payments grow larger with each balance you eliminate. The main advantage of this method is psychological. By seeing a balance hit zero quickly, you may feel a sense of accomplishment that keeps you motivated to stay on track.

In our specific scenario, the total debt is $17,500, and we have a monthly budget of $690 to distribute. The debts consist of a store card of $1,200 at 18.99%, a Visa of $6,800 at 27.49%, and a car loan of $9,500 at 7.9%.

When applying the debt snowball method to these balances:

• First, you target the store card because it has the smallest balance of $1,200.
• Second, you target the Visa with its balance of $6,800.
• Finally, you target the car loan, which is the largest balance at $9,500.

Using this approach, the store card is the first paid off. The total snowball time to become debt-free is 2 years and 8 months. Over this period, the total snowball interest you pay is $3,916. Because you focus on balance size rather than interest rates, you could end up paying more interest overall, but the quick initial win of clearing the store card may provide the momentum you need to keep going.

Understanding the Debt Avalanche Method

The debt avalanche method takes a different approach by focusing strictly on interest rates. Instead of looking at the size of your balances, you list your debts in order from the highest interest rate to the lowest interest rate. You make the minimum required payments on all of your debts, and you put any remaining funds from your monthly budget toward the debt with the highest interest rate.

Once that highest-interest debt is fully paid off, you roll its payment into the debt with the next-highest interest rate. This method is mathematically designed to minimize the amount of interest you pay over time, making it the cheaper method overall.

Let us look at how the debt avalanche method handles the same scenario of $17,500 in total debt with a monthly budget of $690. The debts are prioritized by interest rate:

• First, you target the Visa because it has the highest interest rate of 27.49% (on a $6,800 balance).
• Second, you target the store card because it has the next-highest interest rate of 18.99% (on a $1,200 balance).
• Finally, you target the car loan because it has the lowest interest rate of 7.9% (on a $9,500 balance).

With this strategy, the Visa is the first paid off. The total avalanche time required to clear all balances is 2 years and 7 months. The total avalanche interest paid under this method is $3,708. Because you prioritize the highest interest rate first, you save money over the life of your debt payoff journey.

Step-by-Step Math: Comparing Snowball and Avalanche

To understand why these methods produce different results, it is helpful to look at the step-by-step math of our scenario. We have a total debt of $17,500 and a monthly budget of $690. The three debts are:

• Store card: $1,200 at 18.99%
• Visa: $6,800 at 27.49%
• Car loan: $9,500 at 7.9%

The Snowball Calculation

With the snowball method, we arrange the debts by balance size:

• Store card ($1,200)
• Visa ($6,800)
• Car loan ($9,500)

You focus your extra monthly budget on the store card first. Because the balance is $1,200, the store card is the first paid off. After the store card is cleared, you direct the monthly budget of $690 (minus the other minimums) plus the store card's previous payment toward the Visa. Finally, you move on to the car loan.

• Total interest paid: $3,916
• Total time: 2 years and 8 months

The Avalanche Calculation

With the avalanche method, we arrange the debts by interest rate:

• Visa (27.49%)
• Store card (18.99%)
• Car loan (7.9%)

Here, you focus your extra monthly budget on the Visa first because 27.49% is the highest interest rate. This means the Visa is the first paid off. Even though the Visa balance of $6,800 is much larger than the store card balance of $1,200, targeting it first prevents the high interest rate from rapidly accumulating more debt. After the Visa is paid off, you target the store card, and then the car loan.

• Total interest paid: $3,708
• Total time: 2 years and 7 months

The Difference Between the Methods

When we compare the two results, we can see that the cheaper method is avalanche.

• The avalanche interest is $3,708, while the snowball interest is $3,916.
• The interest difference is $208.
• The avalanche time is 2 years and 7 months, which is 1 month faster than the snowball time of 2 years and 8 months. Given there are 12 months per year, saving a month of payments could help you transition to other financial goals sooner.

While the interest difference is $208, the choice still depends on your behavior. Some people may find that paying off the store card ($1,200) quickly under the snowball method gives them the emotional boost needed to stay committed. Others may prefer the avalanche method because it is mathematically optimized to keep more money in their pocket.

Credit Score Implications During Debt Payoff

Paying down your debt may also have a positive impact on your credit score, which is typically measured on a score range of 300 to 850. Your score is grouped into several score tiers: Poor 300-579, Fair 580-669, Good 670-739, Very good 740-799, and Exceptional 800-850.

When you pay off debt, you are directly influencing the factors that credit bureaus use to calculate your score. Understanding these factors can help you see how your payoff journey may improve your financial standing. Let us look at the Fico weights that determine your score:

• payment history 35%
• amounts owed 30%
• length of history 15%
• new credit 10%
• credit mix 10%

Payment History and Amounts Owed

Payment history is the largest component, making up 35% of your score. Making your minimum payments on time every single month is critical because late payments can stay on credit reports up to 7 years. Whether you choose the snowball or avalanche method, you must continue making minimum payments on all active accounts to protect this portion of your score.

The second largest factor is amounts owed, which accounts for 30% of your score. This factor is heavily influenced by your credit utilization ratio. A general utilization guideline is to keep your credit utilization under 30%, and keeping it under 10% is often better.

In our scenario, paying down the Visa ($6,800) and the store card ($1,200) reduces your overall credit utilization. Under the avalanche method, the Visa is the first paid off, which could rapidly lower your credit utilization because the Visa represents a significant portion of your $17,500 total debt. Under the snowball method, clearing the store card ($1,200) first also helps, but it may take longer to make a major dent in your overall utilization since the Visa balance remains outstanding for a longer period.

New Credit and Inquiries

As you focus on paying off your debts, you should generally avoid applying for new credit lines. Applying for new credit triggers hard inquiries, which can stay on reports for 2 years and usually matter most in the first 12 months. Keeping hard inquiries to a minimum may help protect your score as you transition through different score tiers, such as moving from Fair 580-669 to Good 670-739.

Practical Steps to Start Your Debt Payoff Journey

Regardless of which method you choose, taking action requires a structured approach. Here are the practical steps you can take today to get started:

Gather Your Debt Information

Create a complete list of everything you owe. You may need to gather the balance and the interest rate for each account. For example, in our scenario, we gathered the following details: a store card of $1,200 at 18.99%, a Visa of $6,800 at 27.49%, and a car loan of $9,500 at 7.9%.

Determine Your Monthly Budget

Look at your income and expenses to decide how much money you can realistically put toward your debt each month. In our scenario, the monthly budget is $690. Ensure this amount covers at least the minimum payments for all your debts combined.

Choose Your Strategy

Decide whether you want to use the snowball or avalanche method. If you prefer quick wins to stay motivated, choose the snowball method, where the store card is the first paid off. If you want the cheaper method that saves you an interest difference of $208, choose the avalanche method, where the Visa is the first paid off.

Automate Your Payments

Set up automatic minimum payments for all your debts to ensure you never miss a due date. Late payments can stay on credit reports up to 7 years, so automation could safeguard your payment history. Then, manually direct your extra monthly budget toward your target debt.

Monitor Your Progress

Track your balances as they decrease. Watching your total debt of $17,500 go down month by month can be highly rewarding. As you pay off each balance, your credit utilization could improve, helping you move upward through the credit score tiers.

Final Thoughts

Choosing between the debt snowball and debt avalanche is a personal decision. The avalanche method is the cheaper method, saving $208 and taking 2 years and 7 months to finish in our scenario. The snowball method takes 2 years and 8 months but offers the psychological benefit of paying off the store card first. Whichever path you choose, staying consistent with your monthly budget of $690 is the most important factor in becoming debt-free.
