Snowball vs Avalanche
When tackling multiple debts, such as credit cards, personal loans, or overdrafts, choosing a structured method can significantly impact your journey to financial freedom. Two of the most popular strategies are the Debt Snowball and the Debt Avalanche. While both aim for the same result—becoming debt-free—they take different approaches to how you prioritise your payments.
The Debt Snowball
The Debt Snowball method focuses on psychological momentum. With this strategy, you list your debts from smallest balance to largest balance, regardless of interest rates. You pay the minimum on everything except the smallest debt, to which you direct any extra funds. Once that smallest debt is cleared, you "roll" that payment into the next smallest balance.
The primary advantage of the Snowball method is the "quick win." Clearing a small balance early provides a powerful sense of accomplishment, which can provide the motivation needed to stay on track for the long term. For many, the behavioural boost of seeing a debt disappear completely outweighs the mathematical cost.
The Debt Avalanche
The Debt Avalanche method is built on mathematical efficiency. Instead of looking at balances, you prioritise your debts based on their interest rates. You list your debts from the highest interest rate to the lowest, directing extra payments toward the debt that is costing you the most in interest every month.
By targeting high-interest debt first, you minimise the total amount of interest paid over the life of your debts. Mathematically, the Avalanche method is usually the fastest and cheapest way to clear debt. However, if your highest-interest debt is also your largest balance, it may take a long time to see that first "win," which can be challenging for some.
Which Strategy Should You Choose?
The "best" strategy is the one you can stick to until the end. If you are motivated by numbers and want to pay as little interest as possible, the Avalanche method may be for you. If you find yourself losing steam and need frequent milestones to keep going, the Snowball method's psychological benefits are significant.
