The avalanche method is a debt repayment strategy that focuses on paying off debts in order of their interest rates—from highest to lowest. You make the minimum payment on all your debts, but put any extra money toward the debt with the highest interest rate first. Once that balance is fully paid off, you roll the amount you were paying into the next highest-interest debt, and continue this process until all debts are cleared. This method helps you minimize the total interest you pay over time and can lead to becoming debt-free faster compared to other methods, such as the snowball approach.
