Debt Avalanche vs. Debt Snowball Method

To clear your debt fast, you must make the minimum required payments on all your loans, and then channel 100% of your extra spare cash toward just one target debt. Once that debt is dead, you take all the money you were paying toward it and roll it into the next one.

But which debt should be your first target? There are two proven strategies.

Method 1: The Debt Avalanche (The Mathematical Approach)

The Avalanche method focuses purely on saving you the most money. It ignores the size of your loans and looks only at the interest rate.

• How it works: List your debts from the highest interest rate down to the lowest. Your highest-rate loan becomes your target, regardless of how big the balance is.
• The Pros: This is the mathematically "correct" way to pay off debt. Because you are attacking the debt that charges you the most interest, you will save the most money overall and usually become debt-free months faster.
• The Cons: It can be a long slog. If your highest-interest debt is a massive $15,000 credit card, it might take you a year or two just to cross that first debt off your list. You need strict discipline to stay motivated when progress feels slow.

Method 2: The Debt Snowball (The Psychological Approach)

The Snowball method ignores interest rates entirely. Instead, it focuses on the size of the loan to give you quick, psychological "wins".

• How it works: List your debts from the smallest dollar balance to the largest balance. Your smallest loan becomes your target.
• The Pros: You see immediate results. Wiping out a tiny $500 Afterpay debt or a $1,000 credit card might only take a month or two. That quick victory gives you a rush of dopamine and the motivation to tackle the next one. As you eliminate small debts, you free up cash flow, making your payments "snowball" in size.
• The Cons: Because you are ignoring interest rates, you will pay more to the bank over the long term.

Which One Should You Choose?

If you are a spreadsheet nerd who stays motivated by long-term financial optimization, choose the Avalanche.

If you are stressed, overwhelmed, and have a history of giving up on budgets because they feel too hard, choose the Snowball. The temporary cost of extra interest is worth it if the quick wins are what keep you on the wagon.
