Debt Snowball / Avalanche Calculator

Compare the two most popular debt payoff strategies side by side. Enter your debts and extra payment budget to see how the snowball method (smallest balance first) and avalanche method (highest rate first) differ in payoff time and total interest.

The debt snowball and debt avalanche are two systematic approaches to paying off multiple debts. Both involve making minimum payments on all debts while directing extra money toward one priority debt at a time.

The debt snowball method, popularized by Dave Ramsey, targets the smallest balance first regardless of interest rate. When that debt is paid off, its payment amount rolls into the next smallest balance like a growing snowball. The psychological wins of eliminating debts quickly help maintain motivation.

The debt avalanche method targets the highest interest rate first, which is mathematically optimal and minimizes total interest paid. While it may take longer to pay off the first debt, this method typically saves more money overall. The difference between the two methods grows larger when there is a wide spread in interest rates across your debts.
