Debt Avalanche vs Debt Snowball: Which Repayment Strategy is Better?

Debt can feel overwhelming, especially if you're juggling multiple credit cards, loans, or lines of credit. The good news is that having a plan can make a big difference.

Two of the most popular debt repayment strategies are the debt avalanche and debt snowball methods. Both can help you pay off debt, but they take different approaches. One focuses on saving money on interest, while the other is designed to build motivation through quick wins.

So, which strategy is better?

The answer depends on your financial situation and what will keep you motivated to stick with your repayment plan. Here's how each method works, along with the pros and cons, so you can decide which approach is right for you.

What is the debt avalanche method?

The debt avalanche method focuses on paying off the debt with the highest interest rate first.

You'll continue making the minimum payment on all your debts, but you'll put any extra money toward the balance with the highest interest rate. Once that debt is paid off, you'll roll that payment into the debt with the next highest interest rate.

Example of the debt avalanche method

Let's say you have the following debts:

Using the debt avalanche method, you would pay off your debts in this order:

1. Credit card A (24.99%)

2. Personal loan (11.99%)

3. Car loan (6.99%)

4. Student loan (4.50%)

The balance doesn't matter. The interest rate determines the order.

Pros and cons of the debt avalanche method

Pros

• You pay less interest over time.

• You may become debt-free sooner.

• It's the mathematically most efficient repayment strategy.

• It can save hundreds or even thousands of dollars if you have high-interest debt.

Cons

• It can take longer to pay off your first debt if your highest-interest balance is large.

• Progress may feel slower, making it harder for some people to stay motivated.

What is the debt snowball method?

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

As with the avalanche method, you'll continue making minimum payments on all your debts while putting any extra money toward your smallest balance. Once that's paid off, you'll move to the next smallest balance.

Example of the debt snowball method

Using the same debts:

Your repayment order would be:

1. Credit card A ($4,000)

2. Personal loan ($8,000)

3. Student loan ($10,000)

4. Car loan ($12,000)

If the balances were arranged differently, the repayment order would change, even if another debt had a much higher interest rate.

Pros and cons of the debt snowball method

Pros

• You'll often pay off your first debt sooner.

• Quick wins can help you stay motivated.

• Seeing accounts disappear can make the process feel more manageable.

• Many people find it easier to stick with over the long term.

Cons

• You'll usually pay more interest overall.

• It can take longer to become debt-free.

• It's not always the cheapest repayment strategy.

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

Here's a side-by-side comparison:

Which debt repayment strategy saves more money?

In most cases, the debt avalanche method saves you more money.

That's because high-interest debt, particularly credit card debt, can become expensive if it isn't paid off quickly. By tackling your highest interest rates first, you reduce the total amount of interest you'll pay.

For example, if you have:

• A credit card charging 24.99%

• A line of credit charging 9%

• A car loan charging 6%

Paying down the credit card first will usually reduce your borrowing costs the most.

Which repayment method is more effective?

There isn't a one-size-fits-all answer.

Research into personal finance habits suggests that behaviour matters just as much as the math. If paying off one small debt gives you the confidence to keep going, the snowball method may help you stay consistent. A repayment strategy only works if you stick with it.

On the other hand, if you're motivated by saving money and seeing your interest charges shrink, the avalanche method may be a better fit.

The best strategy is the one you'll continue using until you're debt-free.

Should you pay off credit card debt first?

Often, yes.

Credit cards typically have some of the highest interest rates in Canada. If your credit card also happens to have your highest interest rate, both the avalanche and snowball methods may point you toward paying it off first.

If your credit card balance is relatively small, you'll enjoy both a quick win and meaningful interest savings.

Tips for paying off debt faster

Whichever repayment strategy you choose, these habits can help you make faster progress:

Pay more than the minimum payment

Minimum payments keep your account in good standing, but they also mean you'll pay more in interest over time. Paying even a little extra each month can shorten your repayment timeline.

Put unexpected money toward debt

Tax refunds, bonuses, cash gifts, or work incentives can make a noticeable dent in your balances.

Avoid taking on new debt

If possible, avoid adding new balances while you're paying off existing ones. This helps your repayments move you forward instead of simply replacing old debt with new debt.

Review your budget

Look for subscriptions or recurring expenses you no longer use. Redirecting those savings toward debt can accelerate your progress.

Consider debt consolidation

If you're carrying multiple high-interest debts, consolidating them into a lower-interest loan may reduce your borrowing costs and simplify your payments. It's important to compare your options carefully before consolidating.

What if you're struggling to make payments?

If you're finding it difficult to keep up with your debt payments, don't ignore the problem.

Contact your lender as soon as possible. They may be able to offer temporary payment relief or discuss alternative repayment options.

If your debt feels unmanageable, you can also speak with a non-profit credit counselling organization or a Licensed Insolvency Trustee to understand the solutions available to you.

The bottom line

Both the debt avalanche and debt snowball methods can help you get out of debt.

If your priority is saving as much money as possible, the debt avalanche method is usually the better choice because it reduces the amount of interest you pay.

If your priority is building momentum and staying motivated, the debt snowball method may help you stick with your repayment plan.

Whichever strategy you choose, consistency matters more than perfection. Making your payments on time and steadily reducing your balances can move you closer to becoming debt-free.
