The debt avalanche method is a strategy for paying off debts that prioritizes high-interest debts first. By focusing on the debt with the highest interest rate, you can reduce the total interest paid over time. This method helps you save money and pay off your debts more quickly. To use the debt avalanche method, list all your debts from highest to lowest interest rate. Make minimum payments on all debts except the one with the highest interest rate, to which you allocate any extra funds. Once the highest-interest debt is paid off, move to the next highest, continuing this process until all debts are cleared.
